Intact visual discrimination of complex and feature-ambiguous stimuli in the absence of perirhinal cortex

The perirhinal cortex is known to be important for memory, but there has recently been interest in the possibility that it might also be involved in visual perceptual functions. In four experiments, we assessed visual discrimination ability and visual discrimination learning in severely amnesic patients with large medial temporal lobe lesions that included complete lesions of perirhinal cortex. Experiment 1 tested complex visual object perception. Experiments 2a and 2b tested in two different ways the ability to discriminate between feature-ambiguous images, which was reported to be impaired in monkeys with perirhinal lesions. Experiment 3 involved images that were successfully discriminated in Experiment 2a and asked patients to learn across 20 trials which of the images had been designated as "correct." Patients performed as well as controls in Experiments 1, 2a, and 2b, but one of the patients had difficulty in Experiment 3 when the task required remembering from trial to trial which image was "correct." These findings indicate that perirhinal cortex is not needed for visual perception across a wide range of visual perceptual tasks.     

The practical ethics of linguistic integration: Three challenges

Public debates on linguistic integration as a socially desired outcome often share a prevailing sentiment that newcomers ought to “learn the language.” But the intensity of that sentiment is rarely accompanied by an equally robust understanding of what, precisely, it means in practice. This results in a notion of linguistic integration with an inbuilt tension between a seemingly pragmatic and commonsensical appearance, on the one hand, and a minimal action-guidance capacity, on the other hand. This paper explores this intriguing tension, and it identifies three moral and practical challenges that this challenge presents to the normative theorizing of the practical ethics of linguistic integration: (1) a predicament of arbitrary treatment; (2) the interpersonal structure of social and linguistic learning; and (3) the affective dimension of linguistic integration.     

Subjective value determines initial dominance in binocular rivalry

Does subjective reward value influence early visual perception? During binocular rivalry, one eye receives an image that is incompatible with the image the other eye receives. People consciously experience perceiving one image; the other image is suppressed from conscious awareness. We tested if subjective value functions as an endogenous influence (i.e., one internal to the perceiver) on dominance during rivalry. Images associated with rewards achieved initial perceptual dominance more often than images associated with cost (Study 1, Methods, Participants and procedures, Stimuli and presentation, Experimental counterbalancing conditions, Results, Study 2, Methods, Participants, Stimuli and presentation, Procedure, Results, Reports of letters v. numbers seen as initial percept, Reports of dot location, Study 3). Value facilitated perception of rewarding images but did not inhibit perception of costly images (Study 3). Additionally, when rewards benefited a disliked person, no bias in perceptual dominance was observed. Subjective value biased dominance despite accuracy incentives and was not explained by frequency of exposure, implicit learning, response bias, or task-specific accessibility. We discuss implications for the influence of motivated influences on perception, a phenomenon we call wishful seeing.     

Pathological organizations and psychic retreats in eating disorders

A set of characteristic symptoms allow for the relatively straightforward diagnosis of eating disorders. Simultaneously and paradoxically, underlying the eating disorders are a wide variety of personality organizations/disorders, stretching from the neurotic to the borderline and narcissistic, and even to conditions approaching psychosis. This paper will argue that the inherent commonalities can be ascribed to pathological organizations of a similar nature and quality, operational across the spectrum of eating disorders and functioning in a particular, sadomasochistic way. The typical forms that eating disorders take are based on the specific ways that food and the body are used, that is, symptom manifestation. These distinctive symptom manifestations appear to be related to Steiner's (1982, 1993) notion of a psychic retreat. Pathological organizations and psychic retreats are latent until called upon either sporadically or continuously. When activated, these defensive structures operate like a complex psychic skeleton around which the unique psychodynamics of each patient become rearranged and thereby transformed.     

A Case Study of Witness Consistency and Memory Recovery Across Multiple Investigative Interviews

Access to audio recordings of five interviews (Interviews 2–6), and to the interviewer's contemporaneous notes during an initial unrecorded interview, made it possible to assess consistency across repeated attempts by a 9‐year‐old to describe her older sister's abduction from their shared bedroom. Information provided in each of the interviews was systematically analysed to determine whether each unit of information was new, consistent (repeated) or contradictory in relation to earlier reported information and whether any informative detail provided in the witness' initial interview was subsequently omitted. In addition, the witness' accounts were compared with details provided by the victim upon her rescue. This case analysis is particularly informative in light of widespread professional concerns about the effects of repeated interviewing on the quality and accuracy of children's accounts of experienced events.

From Demonization to Identification: How Parents Who Lost Children in Terrorist Attacks Perceive the Attacker

The aim of this article is to examine how bereaved parents who lost children in terrorist attacks in Israel perceive the terrorist attack perpetrators. Forty bereaved parents were interviewed using a semistructured in-depth interview. The content analysis revealed a typology of reactions to the Arab attackers that included perceiving them as objects of anger, hate, and revenge; as demons; as negligible; and as people with whom they could identify. The way bereaved parents perceive the Arab attackers serves as a coping resource. Follow-up research to examine the efficacy of the different types of reactions towards attackers would contribute to gaining a deeper understanding of the coping process that bereaved parents experience.     

Effects of product type and contextual cues on eliciting naive theories of popularity and exclusivity

This research shows in a series of studies that exposing consumers to functional products evokes the naive theory of popularity, whereas exposing them to self-expressive products induces belief in the naive theory of exclusivity. The research further demonstrates that when the naive theory elicited by product type is matched by the appropriate contextual purchasing cues regarding the interest of others, it results in greater purchase intentions than when those cues are mismatched. The research specifies that the matching effect for functional products is mediated by consumers' perceptions of product quality, whereas mediation for self-expressive products occurs through consumers' self-perceptions regarding the extent to which the product conveys uniqueness. Finally, the research illustrates that an explicit signal of product quality (e.g., a favorable rating in Consumer Reports) attenuates the effect associated with the contextual cues regarding the interest of others.     

A crisis mental health intervention service: an innovative model for working intensively with young people on the edge of care

This paper describes the setting up and the first year of running of an innovative outreach service for adolescents on the edge of care that aimed at redressing family breakdown and preventing placements in the care system. It was a collaborative endeavour between social services and a child and adolescent mental health provision to facilitate the engagement of hard to reach young people and families that often presented high levels of risk. This article describes a distinctive model of applied psychoanalytic work with individuals, families and the networks of practitioners and agencies around the case. It focuses on the integration of two perspectives: the individual and the family on the one hand and the organisation on the other. Case examples illustrate how our psychoanalytic and developmental framework illuminated our understanding of frequently extreme acting out behaviour and parental difficulties in terms of underlying intergenerational trauma, which was often re-enacted. This framework also helped in understanding the difficulties that practitioners experienced and how these related to individual and family dynamics. The article describes the significance of containment in the treatment of adolescents and families in crisis as well as in supporting the professional network.
