Statistical extraction affects visually guided action

The visual system summarizes average properties of ensembles of similar objects. We demonstrated an adaptation aftereffect of one such property, mean size, suggesting it is encoded along a single visual dimension (Corbett, et al., 2012), in a similar manner as basic stimulus properties like orientation and direction of motion. To further explore the fundamental nature of ensemble encoding, here we mapped the evolution of mean size adaptation over the course of visually guided grasping. Participants adapted to two sets of dots with different mean sizes. After adaptation, two test dots replaced the adapting sets. Participants first reached to one of these dots, and then judged whether it was larger or smaller than the opposite dot. Grip apertures were inversely dependent on the average dot size of the preceding adapting patch during the early phase of movements, and this aftereffect dissipated as reaches neared the target. Interestingly, perceptual judgements still showed a marked aftereffect, even though they were made after grasping was completed more-or-less veridically. This effect of mean size adaptation on early visually guided kinematics provides novel evidence that mean size is encoded fundamentally in both perception and action domains, and suggests that ensemble statistics not only influence our perceptions of individual objects but can also affect our physical interactions with the external environment.     

Double foot‐in‐the‐door,social representations,and environment: application for energy savings

This study aims to determine the most effective procedure to bring individuals to adopt pro‐environmental behaviors, specifically to make energy savings for several weeks. A link was established between two fields of research traditionally separated in social psychology literature: free will compliance and social representations theories. An experiment was carried out to test the effectiveness of several simple and double foot‐in‐the‐door procedures, activating central or peripheral cognitions of the social representation of energy savings. Basically, the results indicate that the most effective procedure is the double foot‐in‐the‐door, which activates central cognitions. Twice as many participants accepted the target request and three times as many actually performed the expected behavior with this procedure.     

Gender Now

This paper offers a synthesizing position statement on gender now. Gender has been socially transformed; cultural orders and symbolic meanings have evolved. Gender theory has changed considerably. Kinship as it informs gender has been reconsidered. The binary masculine–feminine complementary relationship between gender and sexuality has been deconstructed. Gender development has been recast in a frame that is both more attuned to social transformations and more fine-tuned to the relational excess that is early human life. Gendered embodiment and fantastic experience is being thought in accord with our recognition of the anxious force of normative regulation. The intricate latticework of gender coherence, bodily coherence, and psychic equilibrium is now open to question. Clinical technique, as one listens to gender now, must also be reframed.     

Deregulated semantic cognition contributes to object‐use deficits in Alzheimer's disease: A comparison with semantic aphasia and semantic dementia

Executive control is impaired from the early stages of Alzheimer's Disease (AD) and this produces deregulated semantic cognition (Corbett, Jefferies, Burns, & Lambon Ralph, 2012 ; Perry, Watson, & Hodges, 2000 ). While control deficits should affect semantic retrieval across all modalities, previous studies have typically focused on verbal semantic tasks. Even when non‐verbal semantic tasks have been used, these have typically employed simple picture‐matching tasks, which may be influenced by abnormalities in covert naming. Therefore, in the present study, we examined 10 patients with AD on a battery of object‐use tasks, in order to advance our understanding of the origins of non‐verbal semantic deficits in this population. The AD patients’ deficits were contrasted with previously published performance on the same tasks within two additional groups of patients, displaying either semantic degradation (semantic dementia) or deregulation of semantic retrieval (semantic aphasia; Corbett, Jefferies, Ehsan, & Lambon Ralph, 2009 ). While overall accuracy was comparable to the scores in both other groups, the AD patients’ object‐use impairment most closely resembled that observed in SA; they exhibited poorer performance on comprehension tasks that placed strong demands on executive control. A similar pattern was observed in the expressive domain: the AD and SA groups were relatively good at straightforward object use compared to executively demanding, mechanical puzzles. Error types also differed: while all patients omitted essential actions, the SA and AD groups’ demonstrations also featured unrelated intrusions. An association between AD patients’ object use and their scores on standard executive measures suggested that control deficits contributed to their non‐verbal semantic deficits. Moreover, in a task specifically designed to manipulate executive demand, patients with AD (and SA) exhibited difficulty in thinking flexibly about the non‐canonical uses of everyday objects, especially when distracted by semantically related objects. This study provides converging evidence for the notion that a failure of regulatory control contributes to multimodal semantic impairment in AD and uniquely demonstrates this pattern for the highly non‐verbal domain of object use.     

Therapeutic Assessment of a Violent Criminal Offender: Managing the Cultural Narrative of Evil

Therapeutic Assessment (TA) emphasizes the importance of the clinical relationship and the core values of collaboration, respect, humility, compassion, and curiosity, which guide all aspects of the endeavor (Finn, 2007 Finn, S. E. (2007). In our clients' shoes: Theory and techniques of Therapeutic Assessment. Mahwah, NJ: Erlbaum. [Google Scholar]). Those values are not easy to apply with violent offenders. However, this article explains how TA can significantly contribute to the treatment of those clients by helping the therapist avoid common cultural narratives about evil. We see that these culturally based myths permit us to explain violent behaviors, but also prevent us from treating them because they lead us to a circular countertransference–transference process. Through a clinical case, I show how the TA process can help us to work empathically with violent people while addressing the dangerousness effectively.     

Emotional enhancement of immediate memory: Positive pictorial stimuli are better recognized than neutral or negative pictorial stimuli

We examined emotional memory enhancement (EEM) for negative and positive pictures while manipulating encoding and retrieval conditions. Two groups of 40 participants took part in this study. Both groups performed immediate implicit (categorization task) and explicit (recognition task) retrieval, but for one group the tasks were preceded by incidental encoding and for the other group by intentional encoding. As indicated by the sensitivity index (d'), after incidental encoding positive stimuli were easier to recognize than negative and neutral stimuli. Participants' response criterion was more liberal for negative stimuli than for both positive and neutral ones, independent of encoding condition. In the implicit retrieval task, participants were slower in categorizing positive than negative and neutral stimuli. However, the priming effect was larger for emotional than for neutral stimuli. These results are discussed in the context of the idea that the effect of emotion on immediate memory enhancement may depend on the intentionality to encode and retrieve information.     

Verbal ability, social stress, and anxiety in children with autistic disorder

The aims of this study were to evaluate the physiological stress and anxiety responses in children with autism following completion of a standardized, social-evaluative stressor (Trier Social Stress Test-Child version), document the relationship between verbal ability, stress, and anxiety, and determine the association between stress and anxiety in children with autism and typical development. Results demonstrated the Trier Social Stress Test-Child version to be a benign stressor for children with autism. Lower verbal ability in children with autism did not predict salivary cortisol or anxiety responses. There was a lack of association between stress and anxiety for both groups, highlighting the importance of considering these terms as separate constructs. Clinical implications and the limited utility of the Trier Social Stress Test-Child version in evaluating psychosocial stress in autism are discussed.
