Background: There is little consensus at policy or treatment level as to what defines ‘recovery’ in the alcohol addiction field. Aim: From interviewing a cohort of eight severely alcohol‐dependent people who fulfilled all categories of DSM‐IV and ICD 10 diagnostic criteria and had achieved long‐term recovery (LTR) of between 8 and 48 years, and who are long‐term AA members, a definition of recovery that is inclusive, and achievable, was sought from their lived experiences. Methodology: Interpretative Phenomenological Analysis was used. Findings: This research uncovers the processes involved in long‐term recovery, and identifies them as: sober; maintaining sobriety; and recovery. It suggests a move away from the acute model of cure by brief, time‐limited therapy, towards a model of sustained, on‐going and life‐long recovery management, combined with pro‐social aid resources. Individuals need to observe, and hear, the success narratives of others, and the therapeutic conditions of empathy, unconditional positive regard and congruence need to be strongly experienced by the individual.

In studies of change blindness, observers often have the phenomenological impression that the blindness is overcome all at once, so that change detection, localization and identification apparently occur together. Three experiments are described that explore dissociations between these processes using a discrete trial procedure in which 2 visual frames are presented sequentially with no intervening inter-frame-interval. The results reveal that change detection and localization are essentially perfect under these conditions regardless of the number of elements in the display, which is consistent with the idea that change detection and localization are mediated by pre-attentive parallel processes. In contrast, identification accuracy for an item before it changes is generally poor, and is heavily dependent on the number of items displayed. Identification accuracy after a change is substantially better, but depends on the new item's duration. This suggests that the change captures attention, which substantially enhances the likelihood of correctly identifying the new item. However, the results also reveal a limited capacity to identify unattended items. Specifically, we provide evidence that strongly suggests that, at least under these conditions, observers were able to identify two items without focused attention. Our results further suggest that spatial pre-cues that attract attention to an item before the change occurs simply ensure that the cued item is one of the two whose identity is encoded.

Flexible, context-dependent linkages between stimulus and response are fundamental to adaptive behavior. In the present article, we evaluate the limits of this flexibility by exploring the asymptotic efficiency of people's ability to switch between two different sensorimotor mappings. Two stimulus-response (S-R) mappings were learned, either both on the same hand ( unimanual condition) or one mapping per hand ( intermanual condition). The S-R mappings presented bivalent stimuli and employed the same response keys. A novel training regimen successfully reduced task-switch costs to approximately 20 msec, suggesting that residual switch costs cannot be eliminated. These costs cannot be entirely attributed to the cognitive control process of task-set reconfiguration, because they are observed over cued switch intervals of several seconds. Two additional issues in motor learning were addressed: the single or dual loci of manual motor control and the coordinate system of task representation. First, the results favored the notion of independent controllers for each hand instead of a single dominant controller, since intermanual performance was superior to unimanual performance. Second, a transfer task tested internal (egocentric) and external (allocentric) coordinate systems. Transfer was more effective using the external coordinate system, suggesting that the S-R mappings reflected the association between the bivalent stimuli and external goals (i.e., the individual keys) rather than the concrete pattern of muscle contractions (i.e., the finger pressing the key). Finally, retention tests revealed that these learned S-R associations were remarkably durable, since no decrements in fluent task-switching performance were observed after 10 months without practice.

Observers (N = 3, all males, M age = 30.7 yr.) were presented pairs of visual targets and instructed to fixate one as quickly as possible. The resulting saccades were of two types; bistable saccades accurately acquired one of the targets whereas averaging saccades landed at intermediate locations. The hypothesis was that averaging saccades result from a pooling of afferent activity prior to selection of saccadic direction and amplitude (i.e., coactive parallel processing) and that bistable saccades would show evidence of response competition between incompatible motor programs within a parallel architecture. Analysis of the distributions of saccadic reaction times showed that in all cases saccadic responses to double targets were too slow to be consistent with either the channel summation or any form of race model. Results indicate that inhibitory interactions operate during the selection of a target for a saccadic eye movement. [ABSTRACT FROM AUTHOR]

Kveraga et al. (2002, Exp Brain Res 146(3):307-14) reported that saccade latencies are immune to the effects of stimulus-response uncertainty and constitute one of the few response systems that violate Hick’s law. Similar effects have been reported for keypresses triggered by vibrations of the fingertips, but robust uncertainty effects were subsequently revealed using weak, low-frequency vibrations (Ten Hoopen et al. 1982, Acta Psychol 50:143-157). We wondered whether immunity of saccadic responses would demonstrate a similar intensity-dependency and therefore re-examined the effects of response entropy on saccade latencies using near-threshold visual stimuli. Saccadic latencies remained independent of stimulus-response uncertainty, indicating that saccadic motor programming is unaffected by the duration of the target detection process.

Studies of tourism motivation and behaviour have not accounted significantly for the aspirations and experiences of ethnic minority groups living in metropolitan societies. This conceptual paper presents a case study of the UK black Caribbean community and seeks to indicate ways in which members of this community perceive places, spaces and destinations in Europe. Attention is directed to how black people's perceptions and experiences are influenced and structured by the social conditions of racialism and racism. The discussion considers how the incursive nature of the white gaze, and popular representations and stereotypes of black societies and cultures, contribute to black people's disengagement from 'tourism experiences'. Racialised experiences and encounters call into question an individual's right to adopt a tourist identity. As the discussion partly focuses on ways in which black visitors perceive 'white others', the work strongly implies that there is a fundamental need to remove the 'white gaze' as the only or dominant way to observe and make sense of the world. Given that this paper contributes to an understanding of how race relations are reproduced within tourism environments, it concludes with suggestions as to how future studies of ethnic minority tourism and travel might be conducted.

There is a commonly held view that gay men, in particular, are frequent and intensive holiday-makers. This is explained by reference to distinctive characteristics relating to income and leisure time and to distinctive values and attitudes. Gay men' s travel patterns are believed to be unique and such as to offer good prospects to those, such as tour operators and hoteliers, willing to target this market. The evidence for these beliefs is examined in this article. Many of the assertions are based on limited-coverage survey samples; recent US evidence suggests that the very positive views of the economic status and distinct purchasing patterns of gays are exaggerated. It is, nonetheless, apparent that there is a market segment that it is `economic' to target but which is unlikely to be representative of gay men. It is apparent that existing surveys are incomplete and are an inappropriate basis for targeting the gay consumer. The article also includes a discussion of marketing approaches to which, it is claimed, gay men are responsive. Whilst the targeting of the gay tourism market does have the effect of validating gay lifestyles, the article includes discussion of other more negative issues that may flow from the perpetuation of the `myth' of the affluent, care-free gay consumer. These include issues such as the generation of a false sense of liberation and distraction from the pursuit of more fundamental aspects of equality. Lifestyle marketing in the context of the gay tourism market has wider and significant implications than those that are usually of direct concern to the marketer; they reach to the core of the nature of homosexuality and its acceptance in society.

This article introduces an understudied source in the history of astronomy, the Astrostereon or the Discourse of the Falling of the Planet (1603). Written by the English astrologer Edward Gresham, this text presents, among other things, the earliest known set of predicted planetary occultations (for 1603–1604) and the use of these phenomena to defend the Copernican cosmology. We analyse those predictions and then briefly survey all known pre-telescopic observations of reported planetary occulations and the motivations for such observations. These data suggest that for early observers, the greater the difference in apparent brightness between the two occulting bodies, the greater the angular separation could be for an occultation nonetheless to be reported. An appendix seeks to explain this finding by considering several factors known from modern experimental analyses of human visual performance. [ABSTRACT FROM AUTHOR]

This investigation brings together a response-time system identification methodology (e.g., Townsend & Wenger Psychonomic Bulletin & Review 11, 391-418, ) and an accuracy methodology, intended to assess models of integration across stimulus dimensions (features, modalities, etc.) that were proposed by Shaw and colleagues (e.g., Mulligan & Shaw Perception & Psychophysics 28, 471-478, ). The goal was to theoretically examine these separate strategies and to apply them conjointly to the same set of participants. The empirical phases were carried out within an extension of an established experimental design called the double factorial paradigm (e.g., Townsend & Nozawa Journal of Mathematical Psychology 39, 321-359, ). That paradigm, based on response times, permits assessments of architecture (parallel vs. serial processing), stopping rule (exhaustive vs. minimum time), and workload capacity, all within the same blocks of trials. The paradigm introduced by Shaw and colleagues uses a statistic formally analogous to that of the double factorial paradigm, but based on accuracy rather than response times. We demonstrate that the accuracy measure cannot discriminate between parallel and serial processing. Nonetheless, the class of models supported by the accuracy data possesses a suitable interpretation within the same set of models supported by the response-time data. The supported model, consistent across individuals, is parallel and has limited capacity, with the participants employing the appropriate stopping rule for the experimental setting.

The article presents information on a study which investigated the effect of changing hypnotists during hypnosis on the depth of hypnosis as measured by performance of specific task items throughout two hypnotic sessions. Nine coeds were alternately hypnotized by a senior hypnotist and one of four junior hypnotists. Subjects completed a cheek list of hypnotic performance and filled out a questionnaire for which they were tested after hypnosis. No observable difference in depth or measured task responses was noted from one hypnotist to the other during hypnosis or between hypnotic sessions.

Abstract: Change blindness illustrates a remarkable limitation in visual processing by demonstrating that substantial changes in a visual scene can go undetected. Because these changes can ultimately be detected using top–down driven search processes, many theories assign a central role to spatial attention in overcoming change blindness. Surprisingly, it has been reported that change blindness can occur during blink-contingent changes even when observers fixate the changing location [O’Regan, J. K., Deubel, H., Clark, J. J., & Rensink, R. A. (2000). Picture changes during blinks: Looking without seeing and seeing without looking. Visual Cognition, 7, 191–212]. However, eye blinks produce a transient disruption of vision that is independent of any associated changes in the retinal image. We determined whether these ‘attentive blank stares’ could occur in the absence of blink-mediated visual suppression. Using a flicker change-blindness paradigm we confirm that despite direct attentive fixations, obvious scene changes often remain undetected. We conclude that change detection involves object or feature based attentional mechanisms, which can be ‘misdirected’ despite the allocation of spatial attention to the position of the change.

Studies of the relationship between stimulus-response uncertainty and reaction times indicate three qualitatively different functions: Hick's law, simple- choice step function, or flat curve (no effect at all). The extent of stimulus-response (S-R) compatibility appears to interact with the effects of uncertainty on response times. One possible hypothesis regarding these various S-R uncertainty functions is that uncertainty will have an effect whenever the stimuli and their associated responses are not within the same egocentric spatial coordinates. We tested this hypothesis in 5 undergraduate participants (2 men, M age 18.7 yr., range 18-20) by investigating the time-course of pointing to peripherally located visual targets under four different levels of uncertainty (1, 2, 4, or 8 possible locations). Surprisingly, the resulting response function does not match any of those previously reported. Visually guided pointing produced a quadratic reaction time function as S-R uncertainty increases in log2 steps from 1 to 8. [ABSTRACT FROM AUTHOR]

Reaction times generally follow the predictions of Hick's law as stimulus- response uncertainty increases, although notable exceptions include the oculomotor system. Saccadic and smooth pursuit eye movement reaction times are independent of stimulus-response uncertainty. Previous research showed that joystick pointing to targets, a motor analog of saccadic eye movements, is only modestly affected by in- creased stimulus-response uncertainty; however, a no-uncertainty condition (simple re- action time to 1 possible target) was not included. Here, we re-evaluate manual joy- stick pointing including a no-uncertainty condition. Analysis indicated simple joystick pointing reaction times were significantly faster than choice reaction times. Choice re- action times (2, 4, or 8 possible target locations) only slightly increased as the number of possible targets increased. These data suggest that, as with joystick tracking (a mo- tor analog of smooth pursuit eye movements), joystick pointing is more closely approximated by a simple/choice step function than the log function predicted by Hick's law.

The article offers assessment techniques for deaf-blind children. It briefly discusses quantitative instruments for use with the deaf-blind such as the Deaf-Blind Program and Ability Test, and the Peabody Intellectual Performance Scale (PIPS). It is pointed out that while the results of behavior checklists can offer a profile of developmental levels of various skills, they are usually not qualified. Meanwhile, standardized intelligence tests offer a way to quantify results, but current instruments cannot be applied to the deaf-blind. Therefore, what is needed is a quantifiable behavior checklist. Norms could then be established for the deaf-blind and normal populations.

Significance: Time-domain functional near-infrared spectroscopy (TD-fNIRS) has been considered as the gold standard of noninvasive optical brain imaging devices. However, due to the high cost, complexity, and large form factor, it has not been as widely adopted as continuous wave NIRS systems. Aim: Kernel Flow is a TD-fNIRS system that has been designed to break through these limitations by maintaining the performance of a research grade TD-fNIRS system while integrating all of the components into a small modular device. Approach: The Kernel Flow modules are built around miniaturized laser drivers, custom integrated circuits, and specialized detectors. The modules can be assembled into a system with dense channel coverage over the entire head. Results: We show performance similar to benchtop systems with our miniaturized device as characterized by standardized tissue and optical phantom protocols for TD-fNIRS and human neuroscience results. Conclusions: The miniaturized design of the Kernel Flow system allows for broader applications of TD-fNIRS. [ABSTRACT FROM AUTHOR]

We investigated whether personally familiar faces are preferentially processed in conditions of reduced attentional resources and in the absence of conscious awareness. In the first experiment, we used Rapid Serial Visual Presentation (RSVP) to test the susceptibility of familiar faces and faces of strangers to the attentional blink. In the second experiment, we used continuous flash interocular suppression to render stimuli invisible and measured face detection time for personally familiar faces as compared to faces of strangers. In both experiments we found an advantage for detection of personally familiar faces as compared to faces of strangers. Our data suggest that the identity of faces is processed with reduced attentional resources and even in the absence of awareness. Our results show that this facilitated processing of familiar faces cannot be attributed to detection of low-level visual features and that a learned unique configuration of facial features can influence preconscious perceptual processing.

Motion is a potent sub-modality of vision. Motion cues alone can be used to segment images into figure and ground and break camouflage. Specific patterns of motion support vivid percepts of form, guide locomotion by specifying directional heading and the passage of objects, and in case of an impending collision, the time to impact. Visual motion also drives smooth pursuit eye movements (SPEMs) that serve to stabilize the retinal image of objects in motion.In contrast, the auditory system does not appear to be particularly sensitive to motion. We review the ambiguous status of auditory motion processing from the psychophysical and electrophysiological perspectives. We then report the results of two experiments that use ocular tracking performance as an objective measure of the perception of auditory motion in humans. We examine ocular tracking of auditory motion, visual motion, combined auditory + visual motion and imagined motion in both the frontal plane and in depth. The results demonstrate that ocular tracking of auditory motion is no better than ocular tracking of imagined motion. These results are consistent with the suggestion that, unlike the visual system, the human auditory system is not endowed with low-level motion sensitive elements. We hypothesize however, that auditory information may gain access to a recently described high-level motion processing system that is heavily dependent on `top-down'' influences, including attention.

Simple reaction times (RTs) are typically faster than choice reaction times and increase with uncertainty according to Hick''s law. Here we show that smooth pursuit eye movement RTs show no effect of SR uncertainty while joystick tracking shows a step change between SRT and CRT, but no significant increases beyond two choices. The results suggest there is a benefit to pre-programming joystick tracking but not for smooth pursuit eye movements (SPEMs). [Copyright &y& Elsevier]
