We addressed the question of whether felony case dispositions are associated with eyewitness identification evidence. Toward this end, 725 felony cases (rape, robbery, and assault) were randomly sampled from the archives of a District Attorney’s Office in a large south-western city in the United States. Positive eyewitness identification evidence was more likely in cases issued compared to those rejected for prosecution although other case factors were associated with issuing outcomes to a larger extent. Additionally, eyewitness identification evidence was stronger in prosecuted compared to rejected cases in which eyewitness testimony was the sole evidence against the defendant. Neither the presence of multiple identifications nor non-identifications of the suspect varied across issuing outcomes. The findings are discussed in relation to additional research that is needed at the police and prosecution stages to advance public policy development with respect to the evaluation of eyewitness identification evidence.

Rape shield laws, which limit the introduction of sexual history evidence in rape trials, challenge the view that women with extensive sexual histories more frequently fabricate charges of rape than other women. The present study examined the relationship between women's actual sexual history and their reporting rape in hypothetical scenarios. Female participants (college students and a community sample, which included women working as prostitutes and topless dancers, and women living in a drug and alcohol rehabilitation center) imagined themselves in dating scenarios that described either a legally definable act of rape or consensual sexual intercourse. Additionally, within the rape scenarios, level of consensual intimate contact (i.e., foreplay) preceding rape was examined to determine its influence on rape reporting. Women were less likely to say that they would take legal action in response to the rape scenarios if they had extensive sexual histories, or if they had consented to an extensive amount of intimate contact before the rape. In response to the consensual sexual intercourse scenarios, women with more extensive sexual histories were not more likely to say that they would report rape, even when the scenario provided them with a motive for seeking revenge against their dating partner.

Originally published in 1980, this title came about after many late night discussions between the authors during a 3-week workshop on Mathematical Approaches to Person Perception in 1974. In subsequent meetings a mutual interest emerged in the development of cognitive information processing metaphors for human thought and their application to problems of social perception, memory and judgment. Within the context of modern research on social cognition, the most distinctive aspects of the authors’ work was its empirical focus on how people cognitively represent people in memory, and its theoretical emphasis on models of cognitive organization and process. They concluded that an adequate theory of social memory was the necessary foundation for solutions to many questions concerning social perception and judgment that had dominated the 1974 workshop. This volume summarizes work conducted between 1974 and 1979 on social memory by these authors. In addition to six chapters summarizing individual research programs, the volume includes a general introduction and a concluding theoretical integration.

OBJECTIVE To compare postprandial blood glucose levels with gastric emptying (GE) time after intake of a solid and a nutrient liquid meal in patients with unstable, type I diabetes. RESEARCH DESIGN AND METHODS The subjects studied were 15 patients with long-standing type I diabetes who during the last year repeatedly reported unexplained episodes of instability in their blood glucose regulation, including postprandial hypoglycemia. All patients were on a meal-administered, fast-acting insulin regimen. As control group, 19 healthy subjects were studied. GE was measured at two separate occasions, using a gamma camera after intake of either a solid or a nutrient liquid, isotope-labeled meal. Measurement of GE was done directly after meal completion and at 30-min intervals for 2 h. Insulin was taken 30 min before intake of the meal. Blood glucose was measured 30 min before the meal, after meal completion and at 30, 60, 90, and 120 min after start of the meal. All patients were evaluated for evidence of autonomic neuropathy and were asked for signs of gastrointestinal motor dysfunction. RESULTS Seven (44%) of the patients had significantly delayed emptying of the solid meal (three men, four women) (P < 0.01), of whom one woman also had delayed emptying of the liquid meal compared with the healthy control subjects. Changes in blood glucose concentration were correlated to GE time with, in the group with delayed GE, a significant fall after the solid meal compared with the liquid meal (P < 0.05). The lag phase was prolonged in the women compared with the men, reaching significance in the patient group (P < 0.01). The women, patients as well as control subjects, had throughout the study a prolonged emptying time compared with the men after both the solid and the liquid meal. No correlation between GE and blood glucose concentration could be found. CONCLUSIONS Delayed GE of a solid meal is commonly found in patients with type I diabetes and may be one cause of unstable blood glucose regulation. Women, patients as well as control subjects, seem to have a more prolonged GE than men. Awareness of gastric function in patients with type I diabetes is essential, especially in patients treated with meal-administered, fast-acting insulin.

BACKGROUNDIn recent years, coaching has received special attention as a method to improve healthy lifestyle behaviours. The fact that coaching has found its way into healthcare and may provide new ways of engaging the patients and making them accountable for their health, justifies the need for an overview of the evidence regarding coaching interventions used in patient care, the effect of the interventions, and the quality of the studies published. However, in order to provide a clear definition of the coaching interventions selected for this review, we have found it necessary to distinguish between health coaching and life coaching. In this review, we will only focus on the latter method and on that basis assess the health related outcomes of life coaching.METHODSIntervention studies using quantitative or qualitative methods to evaluate the outcome of the life coach interventions were identified through systematic literature searches in PubMed, Embase, Psycinfo, and CINAHL. The quality of the methodology was independently assessed by three of the authors using a criteria list.RESULTSA total of 4359 citations were identified in the electronic search and five studies were included; two of them were randomized controlled trials and met all quality criteria. The two studies investigating objective health outcomes (HbA1c) showed mixed but promising results, especially concerning the patient group that usually does not benefit from intensified interventions.CONCLUSIONBecause of the very limited number of solid studies, this review can only present tendencies for patient outcomes and a preliminary description of an effective life coaching intervention.The coaching method used in these studies aims to improve self-efficacy and self-empowerment. This may explain why the studies including disadvantaged patients showed the most convincing results. The findings also indicate that some patients benefit from being met with an alternative approach and a different type of communication than they are used to from health care personnel.In order to get a closer look at what is in the ‘black box’, we suggest that the description and categorisation of the coaching methods are described more comprehensively, and that research into this area is supplemented by a more qualitative approach.

Previous psycho-legal research has claimed that the process of selecting death-qualified jurors for capital cases creates conviction-prone juries. The studies on which these claims are based have employed simulation methodologies to examine the relationship between subjects' death-penalty attitudes and verdict decisions, as well as the effect of the death-qualifying voir dire itself. Despite admitted weaknesses of simulations in general, this method was employed in the present research so that conceptual comparisons to past findings could be drawn. Two experiments were designed to examine the issue of death-qualification and biased juries in a context of other potentially highly influential factors, namely, the strength of evidence and the degree of heinousness. Our results failed to find any of the relationships between death-penalty attitudes and verdict decisions that would be predicted from past research. Instead, the subjects' decisions were influenced, virtually exclusively, by the strength...

This study was performed to explore whether lactate, pyruvate, glucose, and glycerol levels sampled via microdialysis catheters in the transplanted liver could be used to detect ischemia and/or rejection. The metabolites were measured at the bedside every 1 to 2 hours after the operation for a median of 10 days. Twelve grafts with biopsy-proven rejection and 9 grafts with ischemia were compared to a reference group of 39 grafts with uneventful courses. The median lactate level was significantly higher in both the ischemia group [5.8 mM (interquartile range = 4.0-11.1 mM)] and the rejection group [2.1 mM (interquartile range = 1.9-2.4 mM)] versus the reference group [1.5 mM (interquartile range = 1.1-1.9 mM), P0.001 for both]. The median pyruvate level was significantly increased only in the rejection group [185 μM (interquartile range = 155-206 μM)] versus the reference group [124 μM (interquartile range = 102-150 μM), P0.001], whereas the median lactate/pyruvate ratio and the median glycerol level were increased only in the ischemia group [66.1 (interquartile range = 23.9-156.7) and 138 μM (interquartile range = 26-260 μM)] versus the reference group [11.8 (interquartile range = 10.6-13.6), P0.001, and 9 μM (interquartile range = 9-24 μM), P = 0.002]. Ischemia was detected with 100% sensitivity and greater than 90% specificity when a positive test was repeated after 1 hour. In 3 cases of hepatic artery thrombosis, ischemia was detected despite normal blood lactate levels. Consecutive pathological measurements for 6 hours were used to diagnose rejection with greater than 80% sensitivity and specificity at a median of 4 days before the activity of alanine aminotransferase, the concentration of bilirubin in serum, or both increased. In conclusion, bedside measurements of intrahepatic lactate and pyruvate levels were used to detect ischemia and rejection earlier than current standard methods could. Discrimination from an uneventful patient course was achieved. Consequently, intrahepatic graft monitoring with microdialysis may lead to the earlier initiation of graft-saving treatment.

Realization of the cloud computing infrastructure requires access to data anywhere, anytime at any device at a sufficient perceived quality of service. Many Western European countries, such as Denmark, have a high percentage of individuals (inhabitants and companies) that has access to broadband internet via cable, satellite and mobile. This gives a unique position in roll-out and deploying intelligent cloud based services that can be applied for a number of purposes, but where lack of sufficient capacity/quality and IT readiness will be barriers in realization of the "Global Information Multimedia Communication Village (GIMCV)". Broadband is here defined as more than 2 Mbps. In this paper, the combination of e-commerce, cloud computing and broadband infrastructure has our focus, and its unique possibilities for the overall IT society. However, it is also about a significant number of Small and Medium sized Enterprises (SMEs) that today applies manual billing systems or Excel like systems in combination with severe lacks of sufficient IT skills. This means that the most commonly used systems are the ones requiring the most of our time. Therefore, the move for the SME towards e-commerce and electronic processes has a significant economical potential for the SMEs. E-commerce and other internet based services will simplify their business, and hence allow the SMEs to focus on their core business which was their raison d'etre. In addition to this can be added other fundamental IT systems that will help their business, but that is outside the scope of this paper. Furthermore, this paper focuses on infrastructural barriers and cloud computing; not only focusing on bandwidth, but also the entire issue of service offering. Services offered via cloud computing solutions will minimize the SMEs investment in own hardware (HW), software (SW) and maintenance. The focus is also the upgrade to a superior infrastructure that provides the platform for efficient cloud computing, for e-commerce, and beyond.

Almost everyone would agree that the course of forgetting is some curvilinear function of time. The purpose of the research described herein was to identify the nature of that function. Three experiments are reported, two involving human subjects and one involving pigeons. The human experiments investigated this issue using recall of words and recognition of faces, whereas the pigeon experiment employed the standard delayed matching-to-sample task. In all cases, the course of forgetting was best described by a simple power function of time relative to five other reasonable alternatives (linear, exponential, exponential-power, hyperbolic, and logarithmic). Furthermore, a reanalysis of Ebbinghaus's (1885) classic savings function showed that it, too, declines as a power function of time. These findings suggest that the form of forgetting is a relatively robust property of memory performance and that its mathematical description, perhaps only coincidentally, matches that of the psychophysical function.

Two experiments investigated whether remembering is affected by the similarity of the study face relative to the alternatives in a lineup. In simultaneous and sequential lineups, choice rates and false alarms were larger in low compared to high similarity lineups, indicating criterion placement was affected by lineup similarity structure (Experiment 1). In Experiment 2, foil choices and similarity ranking data for target present lineups were compared to responses made when the target was removed from the lineup (only the 5 foils were presented). The results indicated that although foils were selected more often in target-removed lineups in the simultaneous compared to the sequential condition, responses shifted from the target to one of the foils at equal rates across lineup procedures.

The effect of varying the retention interval after an interaction with a stranger on the accuracy of memory for events and for personal identifying characteristics at 2 recall attempts was investigated. Although the number of correct event facts that were recalled decayed as expected, the percentage of recalled facts that were in error remained constant over time. In addition, a single recall attempt prevented further decay in the total amount correctly recalled. In contrast, although the perception of and memory for identifying characteristics varied with the attribute, retention interval had no effect on the accuracy of memory for the person, either at 1st recall or after a 2nd recall at 4 weeks. Confidence was highly predictive of the accuracy of personal descriptions. The relationship between the accuracy of witness descriptions and the probability of arresting an innocent suspect is discussed.

Wixted and Ebbesen (1991) showed that forgetting functions produced by a variety of procedures are often well described by the power function, at−b, where a and b are free parameters. However, all of their analyses were based on data arithmetically averaged over subjects. R. B. Anderson and Tweney (1997) argue that the power law of forgetting may be an artifact of arithmetically averaging individual subject forgetting functions that are truly exponential in form and that geometric averaging would avoid this potential problem. We agree that researchers should always be cognizant of the possibility of averaging artifacts, but we also show that our conclusions about the form of forgetting remain unchanged (and goodness-of-fit statistics are scarcely affected by) whether arithmetic or geometric averaging is used. In addition, an analysis of individual subject forgetting functions shows that they, too, are described much better by a power function than by an exponential.

When a decision making analysis is applied to key decisions within the criminal justice system, e.g., bail, sentencing, and plea bargaining, a wide range of evidence suggests that the decision makers believe they follow policies other than those that actually guide their decisions; that the policies that are followed are often simple ones, involving only a few decision factors; and that the decision outcomes are often assigned to defendants in a reasonable manner but that, even so, the outcomes are often ineffective. Because many proposals for the reform of the criminal justice system are based on the testimony of decision makers and "experts" whose knowledge of the system is often flawed, it is unlikely that reforms will have a beneficial impact on criminal behavior until much more is known about the day-to-day decisions of judges, prosecutors, and probation officers.

The processes people use to retrieve information about another person's behavior and personality were investigated. Subjects viewed different lengths of segments from videotaped sequences of actors' behaviors. The subjects' reaction times to questions about the actors' behaviors and about personality traits were both an increasing function of the duration of the segment about which the questions were asked. These data were taken as an indication that people do, in general, carefully examine the contents of their memories in order to respond to questions about another person. In particular, an exhaustive serial search model was supported. Additional data and analyses demonstrated that relatively abstract trait terms usually were answered on the basis of the exhaustive search, while relatively specific trait terms were not. A two-stage process model was proposed to explain the differences in the results for the two types of trait terms.

The growth of legal psychology in the past ten or so years has been reflected in a relatively large number of edited volumes and symposia at various conventions, in the far greater visibility of psychologists in various interdisciplinary forums (such as the meetings of the American Psychology-Law Society), in the increasing frequency with which psychologists appear as expert witnesses (whose testimony addresses an ever broader range of issues), and, finally, in the founding of this journal. The main purpose of the discipline, presumably, is to explore various aspects of the "interface" between psychology and the law, and, more specifically, to enhance the understanding of the operation of the legal system by using psychological research methods and by testing the validity of psychological assumptions contained in legal statutes or else made by legal practitioners on an ad hoc basis. It appears self-evident that legal psychology has a strong applied orientation. Many psychologists do research in it primarily because the results of their theoretical and empirical efforts can be applied in an obviously important social domain. Many lawyers take an interest in it because they have grudgingly begun to believe that psychologists can make a practical contribution to the judicial process. Furthermore, the research emphasis has been on the various practical aspects of criminal procedure, rather than, for example, on lofty speculations about the role of psychological principles in legal doctrines; namely, a close examination of the literature in legal psychology shows that a very large proportion of all research studies falls into the

The present research examined relationships between physical distance, frequency of face-to-face contacts, and the probability that individuals would be chosen as friends or enemies. Consistent with previous research, the probability of being chosen as a friend increased as the distance between people decreased. There was also a positive linear relationship between the frequency of contact and the strength of linking. In contrast, the probability of being chosen as a disliked individual was even more dependent upon physical distance (more disliked than liked individuals lived close to the subjects), but the strength of disliking was unrelated to the frequency of face-to-face contact. Friends also tended to live farther away from the subjects the longer the latter had lived in their residences, but the distance that disliked individuals lived from the subjects did not depend upon time. The overall pattern of results was consistent with an “environment-spoiling” hypothesis which proposed that many negative interpersonal relationships primarily occur because the actions of specific others spoil one's living environment, whereas most positive interpersonal relationships result from frequent face-to-face contacts.

A field experiment was conducted to determine the effects of expression of verbal aggression on subsequent verbal aggression of angered and nonangered subjects. Subjects who were being laid off their jobs (angry subjects), and subjects who were leaving their jobs for “other reasons” (nonangry subjects), were induced to aggress verbally against the company, their supervisor, themselves, or to discuss neutral topics. In a factorial design, the subjects then filled out one of three “aggression” questionnaires: one concerned the company; another, their supervisors; and the third, themselves. The results indicated that when angered subjects directed verbal aggression at a specific target, their subsequent verbal aggression increased only when it was directed at the same target. However, self-criticism by angered subjects decreased subsequent self-derogation.

Four field experiments were carried out to examine the effects of a violation of personal space on the “victims” subsequent behavior. In Experiment I, it was found that male and female pedestrians crossed a street faster than controls if their personal space had been violated (while stationary before crossing) for 10 sec by an experimenter of the same sex. The remaining experiments examined how a violation of personal space would affect the nature of the subsequent victim-violator interaction, as inferred from the victims' and controls' differential helping of the violator. It was found that, in comparison to controls, a 10-sec stationary violation of pedestrians' personal space decreased the frequency with which they returned to the violator an object he “lost” only if the object was of low value to the violator (a pencil vs keys). However, victims of a combined stationary-and-moving (while walking across the street) violation helped the violator significantly less frequently than controls, irrespective of the value of the lost object. Implications of these results for an attributional analysis of personal space phenomena were discussed.

Two studies were conducted to determine how real felony court judges decide the amount of bail to set. In the first, the judges were presented with fictitious case histories containing the relevant information in a factorial design. In the second, multiple regression techniques were used to examine the impact of different kinds of information on decisions made by judges in actual bail hearings. In the simulated cases, the judges seemed to be influenced most by the degree to which the accused was tied to the area and whether or not he had a prior criminal record. However, the judges' actual bail decisions were not at all affected by these variables. Instead, their decisions were almost exclusively determined by the district attorneys' recommendations. Both the district attorneys' and the defense attorneys' actual recommendations were found to be primarily based upon the severity of the crime. These results were discussed in terms of the utility of simulation and observational research for drawing applied and theoretical conclusions.

Summary Distortions of Estimates of Numerousness and Waiting Time During the gasoline shortage in 1974, 53 male and 36 female San Diego drivers waiting to purchase gasoline were asked to estimate the number of cars ahead of them in the line and the length of time they expected to wait. Unlike situations previously studied, drivers were unaware of the available amount of the commodity. Regressions of both the estimated number ahead on the actual number and the estimated waiting time on the actual time were significant (p < .001). In contrast to previous findings, people close to the end of lines did not underestimate the number ahead. Drivers overestimated irrespective of their position. However, considerable underestimation of the time drivers expected to wait was found throughout the lines, with the amount of underestimation proportionate to the distance from the beginning of the line.

A field study examined the relationship between the drivers' distance from an intersection (0-100 yard (0-91.4 m)) when the light changed from green to yellow, and the probability that the drivers would proceed through the intersection. The function relating the two variables approximated a normal ogive, but there was additional evidence that drivers took both distance and speed into account in deciding whether to proceed or stop. Among the drivers who were at intermediate distances (40-60 yards (36.6-54.8 m)) when the light changed, the younger males were more likely to proceed and to violate the red light than were other drivers. The latter finding could be attributed to the younger males' faster driving and the related tendency to ignore the consequences of the decision conflict induced by the yellow light. /Author/

Three adult human subjects engaged in activities such as reading, sewing, artwork, and candlemaking while living alone in a laboratory apartment 24 hours per day for several weeks. After a baseline period in which the activities were fully available, access to a particular activity (contingent response) was made dependent on engaging in another less-preferred activity (instrumental response). The contingencies produced substantial increases in instrumental responding, and responding decreased toward baseline levels when the dependency was removed. Under the contingent conditions, time earned for the concurrent activity was always less than the baseline level. To determine the contribution of this reduction to the instrumental increase, access to the contingent activity was restricted in the absence of any dependency. The results indicated that increases among responses that filled the newly available time could be selective, e.g., artwork increased when reading was restricted but candlemaking did not. It was concluded that the reductions in the contingent response that accompany contingencies usually do not exclusively determine instrumental increases, but selective increases can contribute to the increase in time devoted to the instrumental response.

This article makes two major points in regard to expert psychological testimony on eyewitness identification. First, the attention devoted by psychologists to eyewitness identification issues is far out of proportion to the incidence of trials involving eyewitness identifications of criminal defendants; furthermore, the often-expressed concern over wrongful convictions is probably misplaced. Second, the experimental methods used in studies of eyewitness performance are fundamentally unsuited for drawing conclusions about actual witnesses. Hence, there is not an adequate scientific foundation for expert psychological testimony on eyewitness identification. Archival research is perhaps the most promising approach to the study of the criminal justice system.

A series of four field studies were conducted to examine how motorists behaved at intersections. In each study, the proportion of drivers who pulled out in front of oncoming cars at varying temporal distances was recorded. In the first study, it was found that the proportion of turns in front of an approaching car was related to the log of the temporal distance between the subjects and the oncoming cars by a normal ogive. The remaining studies examined the effects that the presence of various types of audiences had on this risk-taking function. It was found that being forced to wait in a line of cars before being allowed to turn substantially increased the risks that drivers took, whereas the presence of other cars behind and/or beside the subject's car had no effect on the risk-taking function. A hypothesis explaining these effects in terms of the frustration of being forced to wait was supported while a social facilitation hypothesis was not. It was also discovered that males take more risks than females, a fact which could explain the higher accident rate for males.

The role of altcntional processes in voluntary delay of reward was explored by manipulating children's attention to the rewards for which they were waiting in a delay-of-gratification paradigm. Preschool children waited for a preferred but delayed reward while facing either the delayed reward, a less preferred but immediately available reward, both rewards, or no rewards. The dependent measure was the amount of time they waited for the preferred outcome before forfeiting it for the sake of the less desired but immediately available one. Results contradicted predictions from psychodynamic theory and from speculations concerning self-instructions during "time binding." Unexpectedly, but in accord with frustrative nonreward theory, voluntary waiting time was substantially increased when subjects could not attend to rewards during the waiting period. Implications are discussed for a theory of the development of delay of gratification.

The effects of choice, initial attitude salience, and counterattitudinal behavior salience upon attitudes were examined within a forced-compliance essay-writing paradigm. By examining the interactions between choice and each of the behavior and attitude salience variables, an attempt was made to test the relative utility of cognitive dissonance and self-perception theories. Consistent with both theories, when neither initial attitudes nor behavior were salient, subjects agreed with their essays more under Choice than under No Choice conditions. In partial accord with self-perception theory but contrary to dissonance theory predictions, when initial attitudes were made salient, Choice subjects agreed less with their essays and No Choice subjects agreed more with their essays than when initial attitudes were not made salient. Both theories predict that behavior salience should increase the basic choice effect; in fact, this variable had no effect on final attitudes. A self-estimate theory was proposed to account for the relationships observed among one's perceived choice, perceived extremity of one's essay, and one's final attitude.

✓ The mortality rate, risk of rebleeding, relevant subjective and objective symptoms, and daily functional capacity after a verified subarachnoid hemorrhage (SAH) of unknown etiology were evaluated in 44 patients treated during a 5-year period (1978 to 1983). A vascular basis for the SAH had been excluded by bilateral carotid and vertebral angiography and computerized tomography. The patients were interviewed at a follow-up examination from 3 to 64 months (median 36 months) after the bleed. The results revealed a 5% mortality rate and a 7% risk of rebleeding. Persisting headache and fatigue were found in 40% of patients, 29% had mild demential symptoms, and 5% had persisting and severe objective neurological symptoms. None had developed epilepsy. A normal daily functional capacity was enjoyed by 84%, while 14% had a moderate reduction in these functions, but were independent of help from other persons. One patient (2%) was not fully assessed.

If there is one conclusion about the United States criminal justice system with which most knowledgeable observers of the system would agree, it is that the sentencing of convicted felons is blatantly unfair. Not only does the average length of prison sentences given to offenders convicted of virtually identical crimes vary from one locale to another (see, e.g., Bottomley, 1973; Green, 1961; Hogarth, 1971; O’Donnell, Churgin, & Curtis, 1977), but different judges seem to give completely different sentences to the same offender. For example, in one instance (reported in O’Donnell et al., 1977), after reading the same file describing characteristics of an offender and the nature of his criminal activity (transporting stolen securities across state lines), one federal judge imposed a three-year prison term while another released the offender with only one year of probation.

Recent years have been important changes in research in behavioral decision theory in terms of a shift from a reliance on economic and statistical models to an emphasis on concepts drawn from cognitive psychology. This report constitutes the proceedings of a conference held June 22-24, 1978, for the purpose of exploring the reasons why the changes have come about and discussing the future directions to which they point. The report contains a preface, 14 original chapters, and a reprint, each authored by various people as indicated separately for each contribution, three broad themes are woven throughout the various discussions of how cognitive limitations and processes affect choice and decision behavior. Some chapters focus on fruitful ways to enlarge the range of decision paradigms studied, others provide examples of richer psychological theories for understanding decision behavior, and a few chapters explore mathematical models in a manner to reflect cognitive rather than economic considerations.

Three experiments investigated attentional and cognitive mechanisms in delay of gratification In each study preschool children could obtain a less preferred reward immediately or continue waiting indefinitely for a more preferred but delayed reward Experiment I compared the effects of external and cognitive distraction from the reward objects on the length of time which preschool children waited for the preferred delayed reward before forfeiting it for the sake of the less preferred immediate one. In accord with predictions from an extension of frustrative nonreward theory, children waited much longer for a preferred reward when they were distracted from the rewards than when they attended to them directly Experiment II demonstrated that only certain cognitive events (thinking "fun things") served as effective ideational distractors Thinking "sad thoughts" produced short delay times, as did thinking about the rewards themselves In Experiment III the delayed rewards were not physically available for direct attention during the delay period, and the children's attention to them cogmtively was manipulated by prior instructions While the children waited, cognitions about the rewards significantly reduced, rather than enhanced, the length of their delay of gratification Overall, attentional and cognitive mechanisms which enhanced the salience of the rewards shortened the length of voluntary delay, while distractions from the rewards, overtly or cogmtively, facilitated delay The results permit a remterpretatio n of basic mechanisms in voluntary delay of gratification and self-control

Shallow marine benthic communities around Antarctica show high levels of endemism, gigantism, slow growth, longevity and late maturity, as well as adaptive radiations that have generated considerable biodiversity in some taxa1. The deeper parts of the Southern Ocean exhibit some unique environmental features, including a very deep continental shelf2 and a weakly stratified water column, and are the source for much of the deep water in the world ocean. These features suggest that deep-sea faunas around the Antarctic may be related both to adjacent shelf communities and to those in other oceans. Unlike shallow-water Antarctic benthic communities, however, little is known about life in this vast deep-sea region2,3. Here, we report new data from recent sampling expeditions in the deep Weddell Sea and adjacent areas (748–6,348 m water depth) that reveal high levels of new biodiversity; for example, 674 isopods species, of which 585 were new to science. Bathymetric and biogeographic trends varied between taxa. In groups such as the isopods and polychaetes, slope assemblages included species that have invaded from the shelf. In other taxa, the shelf and slope assemblages were more distinct. Abyssal faunas tended to have stronger links to other oceans, particularly the Atlantic, but mainly in taxa with good dispersal capabilities, such as the Foraminifera. The isopods, ostracods and nematodes, which are poor dispersers, include many species currently known only from the Southern Ocean. Our findings challenge suggestions that deep-sea diversity is depressed in the Southern Ocean and provide a basis for exploring the evolutionary significance of the varied biogeographic patterns observed in this remote environment.
