Mind-reading in strategic interaction: The impact of perceived similarity on projection and stereotyping

In social dilemmas, negotiations, and other forms of strategic interaction, mind-reading—intuiting another party’s preferences and intentions—has an important impact on an actor’s own behavior. In this paper, we present a model of how perceivers shift between social projection (using one’s own mental states to intuit a counterpart’s mental states) and stereotyping (using general assumptions about a group to intuit a counterpart’s mental states). Study 1 extends prior work on perceptual dilemmas in arms races, examining Americans’ perceptions of Chinese attitudes toward military escalation. Study 2 adapts a prisoner’s dilemma, pairing participants with outgroup targets. Study 3 employs an ultimatum game, asking male and female participants to make judgments about opposite sex partners. Study 4 manipulates perceived similarity as well as counterpart stereotype in a principal–agent context. Across the studies, we find evidence for our central prediction: higher levels of perceived similarity are associated with increased projection and reduced stereotyping.     

Histamine reverses a memory deficit induced in rats by early postnatal maternal deprivation

Early partial maternal deprivation causes long-lasting neurochemical, behavioral and brain structural effects. In rats, it causes a deficit in memory consolidation visible in adult life. Some of these deficits can be reversed by donepezil and galantamine, which suggests that they may result from an impairment of brain cholinergic transmission. One such deficit, representative of all others, is an impairment of memory consolidation, clearly observable in a one-trial inhibitory avoidance task. Recent data suggest a role of brain histaminergic systems in the regulation of behavior, particularly inhibitory avoidance learning. Here we investigate whether histamine itself, its analog SKF-91844, or various receptor-selective histamine agonists and antagonists given into the CA1 region of the hippocampus immediately post-training can affect retention of one-trial inhibitory avoidance in rats submitted to early postnatal maternal deprivation. We found that histamine, SKF-91844 and the H2 receptor agonist, dimaprit enhance consolidation on their own and reverse the consolidation deficit induced by maternal deprivation. The enhancing effect of histamine was blocked by the H2 receptor antagonist, ranitidine, but not by the H1 receptor antagonist pyrilamine or by the H3 antagonist thioperamide given into CA1 at doses known to have other behavioral actions, without altering locomotor and exploratory activity or the anxiety state of the animals. The present results suggest that the memory deficit induced by early postnatal maternal deprivation in rats may in part be due to an impairment of histamine mediated mechanisms in the CA1 region of the rat hippocampus.     

Can a modified lineup procedure improve the usefulness of confidence?

In a face recognition, mini-lineup experiment we examined two aspects of the use of confidence about lineups. We modified the lineup procedure attempting to eliminate the difference in confidence–accuracy relationship between positive (old or identification) and negative (new or not present) decisions. In the modified procedure, participants: (1) selected the lineup member that best matched their memory of the target; (2) rated their confidence that the best match was indeed the target; and (3) indicated (yes/no) whether the best match was the target. Although the modified procedure produced higher accuracy than a standard simultaneous procedure, there was no evidence that it affected the confidence–accuracy relationship. Additionally, the modified procedure also allowed us to compare the extent to which confidence ratings versus binary recognition decisions better discriminated studied from unstudied faces. The results revealed a clear advantage for confidence, but indicated that binary responses were also a unique predictor.     

Metachromatic Leukodystrophy and Nonverbal Learning Disability: Neuropsychological and Neuroradiological Findings in Heterozygous Carriers

Metachromatic leukodystrophy (MLD) is an autosomal recessive neurodegenerative disorder due to deficiency of the enzyme arylsulfatase A that leads to progressive, diffuse demyelination. The syndrome of nonverbal learning disability has been attributed to white matter abnormality and has been reported in children with this disorder and in some healthy family member carriers of gene. We examined the neuropsychologic profiles and MRIs of eight members of the family of a 7-year-old girl with this disease, all of whom were heterozygous carriers of the mutation and five of whom were also carriers of the MLD pseudodeficiency gene. All had low normal levels of arylsulfatase A, and seven of the eight had average or better profiles across all assessed neuropsychological domains. The patient's younger sister had a profile with features of the syndrome of nonverbal learning disability despite a normal MRI, whereas two members with minor white matter findings did not. This family does not provide evidence for the syndrome of nonverbal learning disability in heterozygous carriers of the gene for MLD, even when associated with the MLD pseudodeficiency gene.     

Heroic or hubristic? A componential approach to the relationship between perceived transformational leadership and leader–member exchanges

Using an interpersonal approach to self-perceptions, we broke down leaders’ self-perceptions of their transformational leadership behaviour into three components: a target effect (i.e., how leaders are perceived by followers), a perceiver effect (i.e., how leaders perceive followers), and a self-enhancement effect (i.e., idiosyncratic positivity bias in how leaders perceive themselves), and then examined the relationships between these components and the quality of exchanges between leaders and followers (LMX). In a survey study among 60 leaders with 286 followers, we found the target effect in leaders’ self-perceptions of their transformational leadership to be positively related to the quality of LMX, whereas the perceiver effect and self-enhancement effects were negatively associated with LMX. Follower extraversion intensified the positive role of the target effect and the negative role of the self-enhancement effect in the leader–follower exchanges.     

Cognitive Neurorehabilitation of HIV-associated Neurocognitive Disorders: A Qualitative Review and Call to Action

Despite significant advances in the virologic management of HIV infection over the last two decades, effective treatments for HIV-associated neurocognitive disorders (HAND) remain elusive. While pharmacological interventions have yielded some success in improving neurocognitive outcomes in HIV, there is a dearth of rigorous studies examining the efficacy of cognitive rehabilitation for remediating HIV-associated neurocognitive impairment. This qualitative review summarizes and critiques the emerging literature on cognitive and behavioral treatments for HAND, which provides many reasons for optimism, but also has major limitations that underscore the scope of the work that lies ahead. Considering the notable real-world consequences of HAND, the development, validation, and clinical deployment of cognitive neurorehabilitation interventions tailored to the needs of persons living with HIV infection is a priority for clinical neuroAIDS investigators. In describing potential future directions for this endeavor, particular attention was paid to the application of cognitive neuropsychological principles in developing theory-driven approaches to managing HAND, improving everyday functioning, and enhancing HIV health outcomes.     

Deep Incarnation and Kenosis: In,With, Under,and As: A Response to Ted Peters

In this response to Ted Peters, I relate the proposal of deep incarnation to Luther's theology of the real presence of the humanity of Christ in creation. Based on a typology of four distinctive models of kenosis, I furthermore argue that a kenotic view of incarnation and divine creativity does not necessarily imply a divine absence and withdrawal from creation, as presupposed by Professor Peters. Deep incarnation is consistent with a compatibilist view of kenosis, but not with ideas of divine abdication, or metamorphosis. Finally I situate the view of deep incarnation to Scandinavian creation theology and to research programs at the Centre for Naturalism and Christian Semantics, Copenhagen University.     

God,Information, and Complexity: From Descriptive to Explorative Metaphysics

Abstract

Information and complexity have become central concepts in our contemporary worldview. On this background, it is discussed in which sense concepts of information and complexity may apply to theology proper. While the inherited axiom of divine simplicity forbids complexity and plurality as features of divine nature, an argument is developed for the presence of information and complexity in divine life. Three forms of information are proposed as relevant for a contemporary concept of God: Information as difference (Information1), information as form and relational structure (Information2) and semantic information (Information3). It is argued that features of these forms of information must be internal to divine life, if God can properly be said to facilitate and value the complex world of creation, to allow embodied creates to participate in divine life, and to communicate with creatures. In this light, the notion of divine simplicity will have to be redefined as the divine self-identity throughout temporal flux.     

Moral Clarity in Narratives Elicits Greater Cooperation than Moral Ambiguity

In disciplines such as moral psychology and media theory, investigations of moral clarity versus ambiguity in narratives are increasingly important. Untested mechanisms have been proposed for how moral clarity and ambiguity might affect audiences. Based on literature regarding joint action and coordinated experiences, we reason that morally clear narratives elicit coordinated responses across audience members, which should increase within-group cooperation. By contrast, we reason that morally ambiguous narratives elicit divergent, uncoordinated responses across audience members, and this experience decreases cooperation. We conducted three independent studies (one using short text narratives, one using feature-length films, and one using morally and emotionally neutral stimuli). Results indicate that moral clarity is indeed associated with subsequently higher levels of group cooperation than moral ambiguity, and the effect cannot be attributed to changes in affect or moral priming.     

Collected Stories: Play in Four Acts

This article evolved from a group process where members of a psychoanalytic institute were faced with planning workshops for a professional weekend around the theme of “play.” The workshop that evolved consisted of four vignettes of play taking place in the therapeutic sessions of a child, an adolescent, an adult, and an elderly woman. The discussion of these vignettes that began at the conference and then was developed for this article focuses on tracing the development of play from childhood into adulthood (Mayes & Cohen, 1996; Russ, 2004) and on the relationship between play and the development of reflective functioning (Fonagy & Target, 1996). One area of particular interest that was focused upon was the use of play with adults who are described as “concrete,” people who function, at times, at a level of differentiation more typical of a young child. Play is described as being particularly helpful in facilitating a more differentiated and, thus, more reflective mode of psychic functioning for this group of individuals as well as for people at all levels of development.
