This study examines the reliability and validity of proactive (cold-blooded, instrumental), reactive (hot-blooded, affective), and acquisitive (securing goods of others) crime-related attributional domains associated with specific offence-based categories. Using samples from minimum security (n = 116), medium security (n = 102) and parole (n = 116), construct validity of the Proactive, Reactive, and Acquisitive scales was assessed with response latencies, criterion validity with past offending, and predictive validity with future offending. Response latencies for endorsed items discriminated better between the Proactive and Reactive scales than between the Reactive and Acquisitive scales. The Proactive, Reactive, and Acquisitive scales had stronger relationships with their corresponding offense category that with non-corresponding scale and offence-based category. The Acquisitive scale uniquely predicted acquisitive offences. The results support a basic distinction between the Proactive, Reactive, and Acquisitive scales. Implications of the results include using skill-based intervention methods for elevated Proactive scores, affective-based interventions for elevated Reactive scores, and rational choice techniques for elevated Acquisitive scores.

Conventional scientific writing depends upon a highly proscribed complement of models and formulae with clearly defined methodological constraints. The earliest use of affordance I have seen in the music literature comes from Clarke's contemporary, the sociologist Tia DeNora, in her book I Music in Everyday Life i . Responding to an analysis of the opera I Carmen i by musicologist Susan McClary, DeNora seeks an empirical solution to the question of whether the music's gendered connotations are "immanent" or "arbitrary" (DeNora [3], 24). For all the problems with his theory, Moles at least has a similar account of the iterative shaping of musical objects and subjects, and is keen to place an authentic phenomenology of musical experience above purely acoustic representations (Moles [9], 68).

The technical object is said to carry a pure information. This idea is as bold as it is perplexing, seeing that it does not refer straightforwardly to a technical concept, such as negentropy, nor to any semantic sense related to communication. This purity of information can indeed be understood in light of something human, whose trace we find in the technical object, but Simondon once more confounds expectations. Untying the idea of human nature from anthropological, social or even psychological terms, he refers instead to what, in each of us, remains tributary to the metaphysical notion of the unlimited and indefinite (ἄπειρον; ápeiron). We are thus in the presence of an aporia, a puzzlement. To grasp the idea of pure information and to understand it in light of in the human 'ápeiron' requires that we think through the apparently paradoxical notion of an imprint of infinity on the technical object. To help us in this endeavour is Simondon's conception of a power of initiative that marks both human collectivity and the technical object with an axiomatic audacity. [ABSTRACT FROM AUTHOR]

Does reasoning to a certain conclusion necessarily involve a normative belief in support of that conclusion? In many recent discussions of the nature of reasoning, such a normative belief condition is rejected. One main objection is that it requires too much conceptual sophistication and thereby excludes certain reasoners, such as small children. I argue that this objection is mistaken. Its advocates overestimate what is necessary for grasping the normative concepts required by the condition, while seriously underestimating the importance of such concepts for our most fundamental agential capacities. Underlying the objection is the observation that normative thoughts do not necessarily cross our minds during reasoning. I show that proponents of the normative belief condition can accommodate this observation by taking the required normative belief to guide the reasoning process and offer a novel account of what such guidance consists in.

Grasping and object manipulation is a key element of intelligent behavior. Many innovative cyberphysical systems involve some kind of object grasp and manipulation, to the extent that grasping has been recognized as a critical technology for the next generation industrial systems. In this survey, we aim to draw a broad landscape of applications and current research trends and topics relating to grasping techniques and tools. Applications range from biomedical and surgical to industrial warehouse pick and place tasks, covering a wide range of spatial scales, from micro to macro scales. The resources involved and research lines under development include the latest computational intelligence tools as well as the research on new materials and devices for sensing and actuation.

This article grasps the essence of how a science content can be foregrounded by elaborating around concepts as floating and sinking, in relation to boats. The data consist of a videotaped authentic session with one preschool teacher and four children. The model of pedagogical reason and action [Shulman, L. S. 1987. “Knowing and Teaching: Foundations of the New Reform.” Harvard Educational Review 57 (1): 1-23. doi:10.17763/haer.57.1.j463w79r5645541] constitutes the analytical lens. The results show that the content is framed within a series of creative activities where children’s suggestions of how to act are crucial. The scientific content is approached according to the children’s verbalisations of their understandings. Furthermore, dialectical relationships become the main tool when making the content visible.

Using the construct of projective identification and integrating it with the body of literature on intergenerational transmission of unsymbolized parental trauma, I describe the case of an adult daughter that illustrates intergenerational transmission of unsymbolized parental trauma. It is suggested that the daughter has unconsciously identified with the disavowed feelings of anxiety projected into her by her mother. The daughter’s projective identification of her mother’s unresolved past traumas prevent her from leaving the parental home for the first time, despite being 35 years old. In turn, it is thought that the mother’s unconscious grasping onto her daughter is an attempt to avoid the confrontation of her own unprocessed fears implanted into her by her own mother, thus linking three generations of disavowal. As a way of extending the exiting theory, it is proposed that when there are long-term and inexplicable experiences of anxiety that coalesces around the intergenerational transmission of parental trauma, the term ‘intergenerational transmission of traumatic anxiety’ can be used to describe it.

Introduction: Previous studies have demonstrated that students with attention-deficit/hyperactivity disorder (ADHD) struggle particularly with grasping the implicit, inferential level of narratives that is crucial for story comprehension. However, these studies used offline tasks (i.e., after story presentation), used indirect measurements (e.g., identifying main ideas), and/or yielded inconclusive results using think-aloud techniques. Moreover, most studies were conducted with preschool or elementary school children with ADHD, using listening or televised story comprehension. In this study, we were interested in examining the spontaneous, immediate activation and/or suppression of forward-predictive inferences, backward-explanatory inferences, and inference-evoking textual information, as they occur online during reading comprehension by adolescents with ADHD.Method: Participants with and without ADHD read short narrative texts, each of which included a predictive sentence, a bridging sentence that referred back to the predictive sentence via actualization of the predicted event, and two intervening sentences positioned between the predictive and bridging sentences that introduced a temporary transition from the main (predictive) episode. Activation and suppression of inferential and/or textual information were assessed using naming times of word probes that were implied by the preceding text, explicitly mentioned in it, or neither when following control texts. In some cases, a true–false inferential or textual question followed the probe.Results: Naming facilitations were observed for the control but not for the ADHD group, in responding to inference probes that followed the predictive and bridging sentences, and to text probes that followed the predictive sentences. Participants with ADHD were accurate, albeit slower, than controls in answering the true–false questions.Conclusions: Adolescents with ADHD have difficulties in generating predictive and explanatory inferences and in retaining relevant textual information in working memory while reading, although they can answer questions after reading when texts are relatively short. These findings are discussed with regard to development of comprehension strategies for individuals with ADHD. [ABSTRACT FROM PUBLISHER]

This paper describes the classification of various human actions from brain activity. In particular, we focus on grasping movements and estimate grasping patterns from electroencephalogram (EEG) data. EEG data is converted to grasping features by using a common spatial pattern filter (CSP filter), and the features are subsequently classified into grasping categories by using thek-nearest neighbor method. We tested the pipeline of feature extraction and classification on the EEG dataset. The EEG data were acquired while participants grasped an object according to the Cutkosky’s grasping taxonomy, in which grasping movements are categorized into nine power-type grasping patterns and seven precision-type grasping patterns. The best classification rate for 9-class power-type grasping patterns was 48% and for 7-class precision-type grasping patterns was 40%. [ABSTRACT FROM AUTHOR]

This study examined how 5- and 9-year-old children (N = 40) produce pantomimes of object use on verbal request. The task required participants to enact an action with an imagined object. Results showed that with age, children (a) proceeded from body part as object to imaginary object and (b) incorporated into their pantomimes more distinctive features of the object and its use. While the first result replicated previous findings with more items and a more sophisticated coding procedure, the latter result revealed new insights. Children’s selection of distinctive features in pantomime was related to their performance on a semantic odd-one-out task that requires the abstraction of specific features without situational support. The discussion focuses on the cognitive requirements of the task and the potential of pantomime being a reflection of children’s representational development. We suggest an explanation of the findings within the more general developmental model of Karmiloff-Smith. [ABSTRACT FROM AUTHOR]

Background: Evidence-based studies regarding deficits in handwriting performance relative to hand reaching and grasping after a stroke are lacking. Objective: To evaluate the extent of damage to handwriting skills compared to arm reach and grasp task among post-stroke patients. Methods: Eighteen patients and 19 healthy subjects were recruited to this case-control study. Patients were evaluated 15.2 days (±6.5) after the stroke using a Computerized Penmanship Evaluation Tool, surface Electromyography and Fugl-Meyer assessment. This study compared motor deficits in hand reaching and grasping and in handwriting between stroke patients and healthy subjects. Damage to handwriting performance relative to hand reaching and grasping skills was also evaluated. Results: Significant differences were found between groups in handwriting performance (p < 0.05). The performance of the trapezius, biceps, and triceps muscles can predict 63.5% of the variance in the ability to write a short sentence (p < 0.023). Pen pressure can predict 74.9% of the hand motor performance from Fugl-Meyer assessment (p < 0.05). Handwriting was more damaged than was the pattern of activation of the proximal muscles of the shoulder and arm (p < 0.05). FM scores were highly, negatively correlated with the in-air writing time across tasks (r = −0.819,p < 0.004). Conclusions: This study confirms the clinical observation that dexterity skills are more damaged than are arm forward reach after a stroke. However, these differences in motor performance were not significant in mildly disabled patients, demonstrating the feasibility of handwriting rehabilitation in these patients. Therefore, we modestly recommend focusing on handwriting rehabilitation of the hemiparetic upper extremity in mildly impaired patients after a stroke. [ABSTRACT FROM AUTHOR]

ABSTRACT Critiques of contemporary political-economic formations, while grounded in an array of theoretical traditions, have often centered on strategies for relocating power (as embodied in accumulated wealth, control of labor and corporate entities, or the state) in institutions that are nominally more egalitarian or democratic. Such alternative institutions are intended to better represent those who have been historically harmed by the use of power. This article argues for an analytical distinction between such strategies of capturing power on behalf of those without it, and strategies for reducing power differentials directly or annihilating the capacity to accumulate power. We adopt the analytical term subversion to describe these latter efforts to reduce the intensity of, and undermine the capacity to reproduce or deepen, power relationships. Rather than focusing on redistribution or inversion of asymmetrical power relations to benefit the disempowered, subversive strategies work toward decreasing the possibility of accumulating power or, in the extreme case, completely evacuating existing unequal power relations. Thinking about political engagement in terms of limiting the possibility of asymmetrical power relationships (regardless of who holds that power) helps to illuminate a distinction between reactive politics against injustice and proactive politics that pursue alternative, increasingly just conceptual norms. We draw on threads in critical, political, and urban geographies to articulate a particularly geographic concept of 'fleeing-in-place' as subversive resistance to hegemony, the undermining of the possibility of asymmetrical socio-spatial power relations within existing contemporary political economies. We propose strategies for research that better highlight the differences between resistance and subversion. [ABSTRACT FROM AUTHOR]

Background/objective: Some of the behavioral disorders associated with Parkinson’s disease (PD), such as the reduced magnitude of actions (hypometria) may be related to an impairment in cognitive disengagement. A reduced ability to disengage attention from previous sensory stimuli will alter perception with a reduced range of estimated stimulus magnitudes (contraction to the mean). To test this disengagement hypothesis, participants with PD were tested to learn whether they had abnormal sensory perception with overestimation of the relative magnitude of weaker tactile stimuli and underestimation of the relative magnitude of stronger tactile stimuli in relation to a reference stimulus.Design/method: The participants were 12 people with PD and 12 healthy adults. Test stimuli were applied to the palm using Semmes–Weinstein monofilaments (SWM) of 6 magnitudes, 3 greater and 3 less than a standard stimulus. In each trial, after being stimulated with the reference (standard) stimulus, a test monofilament was applied, and the participant was asked to provide a numerical estimate of the magnitude of the second stimulus relative to the standard.Results: Compared to the control group, participants with PD overestimated the magnitudes of the tactile stimuli below the standard stimulus and underestimated the magnitudes of stimuli above the standard stimulus.Conclusions: These results demonstrate that people with PD likely have a reduced ability to estimate the relative magnitudes of tactile sensory stimuli. Whereas deafferentation would alter perception in one direction, the impairment of these participants with PD may result from a disorder of disengagement, and disorders of disengagement are often due to frontal-executive dysfunction.

The article discusses the areas of peace work in which feminist theology has something specific to contribute in the conflict between Israel and Palestine. Topics covered include the violent conceptions of land ownership due to acquisitive theologies of land, the Israeli sovereignty over the region at the cost of Palestinian civil rights, and the alternative understanding of homeland.

Motor resonance refers to the fact that an observed action is online subliminally reenacted. The aim of the present paper was to verify if, on equal terms of kinematics, the to-be-grasped object's intrinsic properties are influencing the observers' motor behaviour. A detection time and a single pulse transcranial magnetic stimulation experiment were performed to verify the effects of a change of object's intrinsic properties artificially made on a video showing a grasping action. In particular, the object substituting the original one was not graspable by the showed movement. Results indicated an influence of object's intrinsic properties: Detection times were delayed and motor evoked potentials were reduced when the movement shown was not suitable to grasp the object. These results are interpreted as an evidence that during grasping action observation the motor system of the observer is influenced not only by the seen movements but also by the to-be-grasped object.

Previous authors have used either a grasping or a locking technique for flexor tendon repair in zone II. A combined (grasping and locking) 10-strand repair was used by the author in 22 adults ( n = 28 fingers) with lacerations of both flexor tendons in zone II. The combined repair is known to be strong (mean tensile strength of 164 N), and the technique was used in selected cases who were thought to be at higher risk of rupture either because of excessive digital oedema (in early tendon repairs) or because of tendon retraction (in late primary tendon repairs). The 10-strand repair was bulky and, hence, only the profundus tendon was repaired; and 'venting' of the pulley system was done proximal to the repair site as recommended by other authors. Supervised early active mobilisation was done immediately after the operation. At final follow-up, the outcome was calculated using the original Strickland-Glogovac grading system. There were no ruptures and the final outcome was considered excellent in 19 patients ( n = 25 fingers), good in two patients ( n = 2 fingers), and fair in the remaining patient ( n = 1 finger). It was concluded that the bulky 10-strand repair may be used for zone II finger flexor tendon lacerations as long as a profundus-(?) only repair and 'venting' of the pulley system are performed.

Priming effects were tested on the planning of the grasping of common objects under full vision during action performance. Healthy participants took part in four experiments which manipulated the nature of the prime (objects, circular block, rectangular bar) and priming context (blocked vs. mixed). Each experiment relied on four priming conditions: (1) congruent orientation, (2) incongruent orientation, (3) neutral prime, and (4) no prime. Priming was observed to have a facilitating effect on visually guided grasping when the object to be grasped was primed by a congruently oriented identical object. This effect was rather independent of the priming context (experimental set-up). Our data suggest an object's functional identity may contribute to the priming effect, as well as its intrinsic (e.g., shape, size) and extrinsic (orientation) visual characteristics. We showed that the planning of visually guided grasping is influenced by prior visual experience, and thus that grasping is not based exclusively on real-time processing of visual information.

This essay explores the “wealth of openness” Heidegger leaves open for the animals. This other open provides a possible outside beyond the dialectic of human-animal as figured by Agamben's anthropological machine. Producing ways of thinking this beyond serves as the frame by which essays in this collection are then introduced. [ABSTRACT FROM AUTHOR]

Influences on the perception of affordances (i.e., opportunities for actions) have been primarily studied by manipulating the functional morphology of the body. However, affordances are not just determined by the functional morphology of the perceiver, but also by the physiological state of the perceiver. States of anxiety have been shown to lead to marked changes in individuals’ physiological state and their behaviour. To assess the influence of emotional state on affordance perception, the perception of action capabilities in near space was examined after participants completed an anxiety-provoking task. Anxiety was induced immediately prior to tasks that assessed participants' perceived reaching ability in Experiment 1, grasping ability in Experiment 2, and the ability to pass their hands through apertures in Experiment 3. Results indicated that those participants who experienced changes in anxiety underestimated their reaching, grasping, and passing ability compared to non-anxious participants. In other words, anxious participants were more conservative in their estimations of their action capabilities. These results suggest that anxiety influences the perception for affordances in near space and are consistent with the notion that anxiety induces withdrawal behaviours. [ABSTRACT FROM PUBLISHER]

There is a need for a strong suture technique that allows early active mobilisation after repair of flexor tendons, but the best method has not yet been found. The aim of this study was to compare the modified Kessler suture biomechanically with a newer, two-strand suture. Eighteen porcine tendons were cut and repaired according to either the grasping modified Kessler suture or the combined side-locking loop technique (Yotsumoto) and interlocking horizontal mattress suture (Dona). The specimens were tested linearly to failure. The 2 mm gap force, yield force, ultimate force, stiffness, energy to yield, and energy to failure were all significantly higher ( p value = 0.005, 0.003, <0.001, 0.001, 0.004, and 0.001, respectively) in the Yotsumoto-Dona group (median values (IQR): 30.9 (28.1-39.5) N, 82.7 (64.9-114.1) N, 82.7 (76.6-114.1) N, 12.5 (10-14.5) N/mm, 0.45 (0.2-0.5) J, and 0.45 (0.35-0.5) J) than in the modified Kessler group (25.8 (12.2-28.1) N, 35 (24.6-54.4) N, 50.9 (34.4-55.1) N, 7 (5.8-91) N/mm, 0.09 (0.06-0.18) J, and 0.21 (0.18-0.28) J). All Yotsumoto-Dona specimens had a yield force exceeding 35 N, while in the Kessler group only four did. The early yielding rate was 6/9 and 2/9 in the modified Kessler and the Yotsumoto-Dona groups, respectively ( p = 0.15). Most of the core sutures failed by breakage, but three Yotsumoto knots loosened. All the simple running and six of the Dona epitendinous sutures failed predominantly by pulling-out, and by breakage at the intersections in three of the latter. The relatively easy two-strand Yotsumoto-Dona suture is likely to withstand the loads of active finger flexion, whereas the modified Kessler suture is probably not. [ABSTRACT FROM AUTHOR]

Humans must coordinate approach–avoidance behaviours with the social cues that elicit them, such as facial expressions and gaze direction. We hypothesised that when someone is observed looking in a particular direction with a happy expression, the observer would tend to approach that direction, but that when someone is observed looking in a particular direction with a fearful expression, the observer would tend to avoid that direction. Twenty-eight participants viewed stimulus faces with averted gazes and happy or fearful expressions on a computer screen. Participants were asked to grasp (approach) or withdraw from (avoid) a left- or right-hand button depending on the stimulus face's expression. The results were consistent with our hypotheses about avoidance responses, but not with respect to approach responses. Links between social cues and adaptive behaviour are discussed.

This study examined the ability of children with hemiplegia to perform motor imagery of their unaffected hand. Children (8–12 years) formed three groups—R-HEMI: right-sided hemiplegia, n = 21; L-HEMI: left-sided hemiplegia, n = 19; and Comparisons, n = 21. We expected no group differences on a simple imagined grasping task, but the hemiplegia groups to perform atypically on an imagined pointing task. Results showed no group differences on the grasping task, while only the L-HEMI group performed atypically on the pointing task— the functional level of the children played a likely role in this finding. Children with hemiplegia can engage in motor imagery, although task complexity and functional level may have an impact. [ABSTRACT FROM AUTHOR]

The goal of this study was to evaluate the relationship between object-related handedness and handedness for communicative gestures. We observed 22 infants aged 14 months on a baby laterality test consisting of grasping objects in different conditions, on a pointing task with targets placed out of reach at different spatial positions from left to right, and on word understanding and word production. Results show that 77% of infants pointed to the left, middle, and right targets. The majority of infants were right-handed for pointing-except for the far left target-and, to a lesser extent, for grasping objects, but there was no significant relation between the two measures of handedness. The frequency of pointing tended to be related to the number of words understood, and infants right-handed for pointing understood and produced significantly more words than non-right-handed pointers. These results are interpreted as confirming the link between pointing and language development, and as showing that communicative gesture lateralisation is not a mere consequence of object-related handedness, at least during development. Whether lateralised communicative gesture reinforces a pre-existing tendency to use the right hand to interact with objects remains an open question. [ABSTRACT FROM AUTHOR]

Background: Compulsive buying is a chronic, repetitive purchasing that becomes a primary response to negative events and feelings, and may include symptoms equivalent to craving and withdrawal. Objectives: This article describes the addictive characteristics of compulsive buying, the psychiatric comorbidity, and the possibilities of treatment. Methods: Using PubMed and MedLine search engines, we performed a review of published literature over the period 1990–2010 using the keyword “compulsive buying”. Results: A key feature distinguishing compulsive buyers from normal consumers, collectors, and hoarders is that the former focuses on the buying process itself, rather than the items bought. In this instance, the purchased items are usually never used, but tend to be hidden or thrown away. A recent screening study found that up to 5% of adult Americans appear to be afflicted with this compulsion. Compulsive buying results in adverse consequences, including financial and legal problems, psychological distress (depression, guilt), and interpersonal conflict. The most commonly associated comorbidities are depression and eating disorders. Nothing is known about the neurobiology and genetics of compulsive buying and relatively little about its treatment. Cognitive behavioral therapy has some efficacy, but no medication has been effective in controlled trials. Conclusions: Compulsive buying can be described as a behavioral dependence. A great deal of future research is needed to improve our understanding of compulsive buying. [ABSTRACT FROM AUTHOR]

The authors studied the effects of surface friction at the digit-object interface on digit forces and moments when 12 participants statically held an object in a 5-digit grasp. The authors changed low-friction contact (LFC) with rayon and high-friction contact (HFC) with sandpaper independently for each digit in all 32 possible combinations. Normal forces of the thumb and virtual finger (VF), an imagined finger with a mechanical effect equal to that of the 4 fingers, increased with the thumb at LFC or with an increase in the number of fingers at LFC. When the thumb was at LFC, the thumb tangential force decreased. The VF tangential force decreased when the number of fingers at LFC increased. The interaction of the local responses to friction and the synergic responses necessary to maintain the equilibrium explain the coordination of individual digit forces. [ABSTRACT FROM AUTHOR]

Background : The Mirror System Hypothesis offers the mirror system for grasping (i.e., neural mechanisms active for both execution and observation of grasping) as a neural “missing link” between the brains of our non‐human ancestors of 20 million years ago and the modern human language‐ready brain, stressing the importance of manual gesture in the evolution of mechanisms supporting language. Aims : To assess the view that neural mechanisms for both praxis and language share an evolutionary relationship to the ancestral mirror system for grasping. Main Contribution : The praxis system receives a new analysis based on the attempt to link human praxis to computational models of execution and observation of grasping in the macaque as well as the analysis of parallels between language and praxis. Conclusions : The conceptual analysis presented here may prove insightful for clinicians seeking to relate and differentiate aphasia and apraxia. [ABSTRACT FROM AUTHOR]

Observers often tend to misremember the visual stopping point of a movement in the direction of movement (representational momentum). We investigated whether this forward displacement also occurs in grasping. We asked participants to close virtual pliers after the pliers had been opening or closing. The participants' thumbs and index fingers were attached to robot arms which allowed us to provide haptic feedback about the location of the pliers' handles. In a visual task, participants judged the remembered final opening width of the pliers relative to a comparison stimulus. For grasping, we found forward displacement: participants opened their fingers wider if the pliers had been opening compared to when they had been closing. In contrast, we did not find clear forward displacement in the visual task. The effects in grasping and the visual task were not correlated between participants. These results seem to argue against the existence of one form of anticipation that serves both perception and grasping. [ABSTRACT FROM AUTHOR]

Adults are proficient at reaching to grasp objects of interest in a cluttered workspace. The issue of concern, obstacle avoidance, was studied in 3 groups of young children aged 11-12, 9-10, and 7-8 years (n = 6 in each) and in 6 adults aged 18-24 years. Adults slowed their movements and decreased their maximum grip aperture when an obstacle was positioned close to a target object (the effect declined as the distance between target and obstacle increased). The children showed the same pattern, but the magnitude of the effect was quite different. In contrast to the adults, the obstacle continued to have a large effect when it was some distance from the target (and provided no physical obstruction to movement). [ABSTRACT FROM AUTHOR]

For as long as man has been on this earth, envy and greed have performed a duet of destruction. Indeed, these terrifyingly complimentary emotions have been at the root of the worlds' great conflicts and can be seen featuring as a point of origin in what are euphemistically referred to as 'crimes of passion'. In biblical accounts, both were sighted amongst the seven deadly sins. An impressively awesome curriculum vitae indeed. In this paper I should like to explore the role of envy and greed in the formation of anorexia nervosa, where it would appear that the destructive nature of this powerful duo have been turned inwards against the body itself. Analytical theorists make much of the difficulties evoked by the Oedipal situation. These particular theories are explored at length and applied to anorexia nervosa. In attempting to understand how this painful stage of development impacts upon this client group, the difficulties posed and the coping strategies employed to alleviate them are both examined. A further avenue discussed is the particular challenge anorexia nervosa sufferers pose to those of us who would seek to engage them in therapy. Anorectic difficulties in engaging and accepting therapy are explored and understanding is sought as to how we might begin to make progress with this most intractable of illnesses. I would like to illustrate these issues by utilizing my experiences of working clinically with a client suffering from an enduring eating disorder. [ABSTRACT FROM AUTHOR]

We investigated participants' ability to use internal representations of the environment to guide prehensile movements, when visual feedback was not available. Reaching and grasping performed with concurrent visual feedback was compared to conditions in which participants actively formed spatial images and passively encoded images from visually presented information. Movement times, the proportion of time spent after peak velocity and peak apertures, were greater when concurrent visual feedback was unavailable. Movement times increased as a function of premovement occlusion length, with passively encoded images resulting in shorter movement durations than actively formed images. The findings indicated that participants adapted their movement trajectories to compensate for the degradation of stored spatial information, when concurrent visual feedback was not available.

An introduction is presented in which the editor discusses various reports within the issue on topics including the practices how objects pass into visibility, an analysis of the contact points between study of absence and ignorance and the importance of not overestimating what is being grasped.

The article presents a study of the validity of the prosimian Microcebus murinus model in studying the grasping disorders in Parkinson's disease. In the study, the grasping biomechanics invariants were pointed out and the existence of these invariants in humans and the model is demonstrated. The findings supply a quantitative tool for assessing the ability to spawn the motor disorder of Parkinson's disease in animals and to test the effect of new therapeutic molecules on grasping disorders.
