Processing of compound visual stimuli by children with autism and Asperger syndrome

A typical modes of visual processing are common in individuals with autism. In particular, and unlike typically developing children, children with autism tend to process the parts of a complex object as a priority, rather than attending to the object as a whole. This bias for local processing is likely to be due to difficulties in assembling subparts into a coherent whole, as proposed by Frith ( 10 1989) using the term “weak central coherence” or WCC. This study was aimed to better characterize the processing of complex visual stimuli by children with autism. Thirteen children with autistic spectrum disorders were individually paired with children of two control groups, one matched on verbal mental age (VMA) and one matched on chronological age (CA). Participants from the three groups were tested in two tasks. The first task involved hierarchical global/local stimuli, inspired by Navon ( 30 1977). The second task employed compound face‐like or geometrical stimuli. This task emphasized the processing of configural properties of the stimuli (i.e., spatial relationships). Children from the three groups showed a perceptual bias favouring the global dimension of the stimuli in the first task. By contrast, children with autism were deficient compared to normal children for the processing of the configural dimensions of the stimuli in the second task. These results suggest that visual cognition of children with autism is characterized by a dissociation between global and configural processing, with global processing being preserved and configural processing being altered in these children, therefore delineating the extents and limits of the WCC theory (Frith, 10 1989).     

Agent Reliabilism,Subjective Justification,and Epistemic Credit

In this paper I examine John Greco's agent reliabilism, in particular, his requirement of subjective justification. I argue that his requirement is too weak as it stands to disqualify as knowledge claims some true beliefs arrived at by reliable processes and that it is vulnerable to the “value problem” objection. I develop a more robust account of subjective justification that both avoids the objection that agents require beliefs about their dispositions in order to be subjectively justified and explains why knowledge is more valuable than true belief.     

An Experimental Analysis of the Effects of Reading Interventions in a Small Group Reading Instruction Context

The current study examined the effects of several combinations of instructional and motivational interventions on oral reading fluency in the context of small group reading instruction. A treatment package consisting of acquisition, fluency, and motivational components was examined and then dismantled. Results were evaluated individually for each participant using a multiple-probe design in order to identify the most effective, yet efficient reading intervention package for each member of the group. The results indicated that, although all potential combinations of the package were effective, the experimental analysis was able to identify an effective yet more efficient package that produced substantial increases in performance across all students. Results are discussed in terms of effective instructional components in small group instruction and how to adapt methods for the experimental analysis of behavior to make decisions about the effectiveness of small group instruction in reading.This study is based on a dissertation submitted by the first author in partial fulfillment of requirements for the doctoral degree.     

Legal realisms: on law and politics

The focus of this work is the issue of whether, and to what extent, the nature of the law is affected by politics, has been taken up by the American and Scandinavian legal realists. By the very fact of their being products of␣the socio-political conditions of the most recent century, the American and Scandinavian legal realisms are the movements that have most explicitly and systematically brought to the surface one particular characteristic phenomenon of contemporary Western legal systems: the existence of two basic forces simultaneously attracting and repelling, affecting the law in its relations with the political world.I would like to deeply thank Brian Bix, Laura Carlson, Roger Cotterrell and Jori Munukka for their many helpful comments on earlier drafts of this article. Any errors remaining are my own.     

On Cognition,Need, and Action: How Working Memory and Need for Cognition Influence Leisure Activities

The present study examined the relationships among college students' need for cognition (NFC), their working memory capacity, and their preferred leisure activities. Results indicated that scoring higher on the NFC scale was related to participants engaging in cognitively higher load leisure activities (e.g., writing) than lower load leisure activities (e.g., watching TV). We did not find a relationship between participants' cognitive ability (as measured by an attentional capacity task) and their choice of leisure activities. In sum, personal dispositions contributed to the choice and complexity of people's leisure activities, whereas cognitive ability did not. These findings provide a theoretical framework for further exploring the relationships between disposition, cognition, and action. Copyright © 2014 John Wiley & Sons, Ltd.     

The contribution of familiarity to within- and between-domain associative recognition memory: Use of a modified remember/know procedure

The purpose of the present study was to determine the extent to which familiarity can support associative recognition memory as a function of whether the associations are within- or between-domain. Standard recognition and familiarity only performance were compared in different participants, using a new adaptation of the remember/know procedure. The results indicated that within-domain (face–face) associative recognition was mainly supported by familiarity. In contrast, familiarity provided relatively poor support to between-domain (face–name) associative recognition for which optimal performance required a major recollection contribution. These findings suggest that familiarity can support associative recognition memory, particularly for within-domain associations, and contrast with the widely held view that associative recognition depends largely on recollection.     

GENDER, JEALOUSY, AND REASON

Abstract— Research has suggested that men are especially bothered by evidence of their partner's sexual infidelity, whereas women are troubled more by evidence of emotional infidelity. One evolutionary account (Buss, Larsen, Westen, & Semmelroth, 1992) argues that this is an innate difference, arising from men's need for paternity certainty and women's need for male investment in their offspring. We suggest that the difference may instead be based on reasonable differences between the sexes in how they interpret evidence of infidelity. A man, thinking that women have sex only when in love, has reason to believe that if his mate has sex with another man, she is in love with that other. A woman, thinking that men can have sex without love, should still be bothered by sexual infidelity, but less so because it does not imply that her mate has fallen in love as well. A survey of 137 subjects confirmed that men and women do differ in the predicted direction in how much they think each form of infidelity implies the other, proposing innate emotional differences may, therefore, be gratuitous.
