Preschoolers search for hidden objects

The issue of whether young children use spatio-temporal information (e.g., movement of objects through time and space) and/or contact-mechanical information (e.g., interaction between objects) to search for a hidden object was investigated. To determine whether one cue can have priority over the other, a dynamic event that put these cues into conflict was created, with only spatio-temporal information being valid. The 3-year-olds used in the study were found to use the valid spatio-temporal cue exclusively and seemed to ignore the contact-mechanical cue. Both search behavior and eye tracking during the event support the view of a sophisticated sensitivity to the validity of a cue in indicating a target’s hidden location.     

"What about me?" Perceptions of exclusion and whites' reactions to multiculturalism

A 5-study investigation of reactions of dominant group members (i.e., White Americans) to diversity (relative to racial minority reactions) provides evidence of implicit and explicit associations between multiculturalism and exclusion and of a relationship between perceived exclusion and reactions to diversity. In Study 1, Whites but not racial minorities were faster in an implicit association task at pairing multiculturalism with exclusion than with inclusion. This association diminished in Study 2 through a subtle framing of diversity efforts as targeted toward all groups, including European Americans. In Study 3, in a "Me/Not Me" task, Whites were less likely than minorities to pair multiculturalism concepts with the self and were slower in responding to multiculturalism concepts. Furthermore, associating multiculturalism with the self (Study 3) or feeling included in organizational diversity (Study 4) predicted Whites' endorsement of diversity and also accounted for the oft-cited group status difference in support for diversity initiatives. Study 5 showed that individual differences in need to belong moderated Whites' interest in working for organizations that espouse a multicultural versus a color-blind approach to diversity, with individuals higher in need to belong less attracted to organizations with a multicultural approach. Overall, results show that the purportedly "inclusive" ideology of multiculturalism is not perceived as such by Whites. This may, in part, account for their lower support for diversity efforts in education and work settings.     

Direct and distal effects of noncontingent juice on rumination exhibited by a child with autism

Previous research has demonstrated the efficacy of the noncontingent delivery of foods and liquids at suppressing rumination, the repeated regurgitation and rechewing of partially digested food. However, it is unclear how long this reduction is maintained after caregivers terminate this procedure. The current study examined the direct and distal effects of noncontingent juice on rumination by measuring the duration of rumination during juice delivery and immediately following the termination of juice delivery. Noncontingent juice suppressed rumination, but this suppression was not maintained after delivery termination.     

The role of system-justification motivation, group status and system threat in directing support for hate crimes legislation

We examine factors that explain variability in attitudes toward hate crimes legislation. We find that one's posture toward the current social system directs the conditions under which characteristics of hate crimes exert the most influence. System-justification motivation is negatively related to support for hate crimes legislation (Studies 1-3). This relation is partially mediated by perceptions of harm from hate crimes. Specifically, when hate crimes target low-status groups, system-justification motivation is negatively related to perceived harm and support for hate crimes legislation. Attitudes are unaffected when high-status groups are targeted. The status of the group targeted, perceptions of hate crimes as representative of the status quo, and temporarily enhanced feelings of system threat moderate this relation (Studies 2-4).     

A biopsychosocial formulation of pain communication

We present a detailed framework for understanding the numerous and complicated interactions among psychological and social determinants of pain through examination of the process of pain communication. The focus is on an improved understanding of immediate dyadic transactions during painful events in the context of broader social phenomena. Fine-grain consideration of social transactions during pain leads to an appreciation of sociobehavioral events affecting both suffering persons as well as caregivers. Our examination considers knowledge from a variety of perspectives, including clinical health psychology, social and developmental processes, evolutionary psychology, communication studies, and behavioral neuroscience.     

Information theory,evolutionary computation,and Dembski’s “complex specified information”

Intelligent design advocate William Dembski has introduced a measure of information called “complex specified information”, or CSI. He claims that CSI is a reliable marker of design by intelligent agents. He puts forth a “Law of Conservation of Information” which states that chance and natural laws are incapable of generating CSI. In particular, CSI cannot be generated by evolutionary computation. Dembski asserts that CSI is present in intelligent causes and in the flagellum of Escherichia coli, and concludes that neither have natural explanations. In this paper, we examine Dembski’s claims, point out significant errors in his reasoning, and conclude that there is no reason to accept his assertions.     

Age differences in the perception of hierarchical structure in events

Everyday activities break down into parts and subparts, and appreciating this hierarchical structure is an important component of understanding. In two experiments we found age differences in the ability to perceive hierarchical structure in continuous activity. In both experiments, younger and older adults segmented movies of everyday activities into large and small meaningful events. Older adults’ segmentation deviated more from group norms than did younger adults’ segmentation, and older adults’ segmentation was less hierarchically organized than that of younger adults. Older adults performed less well than younger adults on event memory tasks. In some cases, measures of event segmentation discriminated between those older adults with better and worse memory. These results suggest that the hierarchical encoding of ongoing activity declines with age, and that such encoding may be important for memory.     

Opposing amygdala and ventral striatum connectivity during emotion identification

Lesion and electrophysiological studies in animals provide evidence of opposing functions for subcortical nuclei such as the amygdala and ventral striatum, but the implications of these findings for emotion identification in humans remain poorly described. Here we report a high-resolution fMRI study in a sample of 39 healthy subjects who performed a well-characterized emotion identification task. As expected, the amygdala responded to THREAT (angry or fearful) faces more than NON-THREAT (sad or happy) faces. A functional connectivity analysis of the time series from an anatomically defined amygdala seed revealed a strong anticorrelation between the amygdala and the ventral striatum/ventral pallidum, consistent with an opposing role for these regions in during emotion identification. A second functional connectivity analysis (psychophysiological interaction) investigating relative connectivity on THREAT vs. NON-THREAT trials demonstrated that the amygdala had increased connectivity with the orbitofrontal cortex during THREAT trials, whereas the ventral striatum demonstrated increased connectivity with the posterior hippocampus on NON-THREAT trials. These results indicate that activity in the amygdala and ventral striatum may be inversely related, and that both regions may provide opposing affective bias signals during emotion identification.     

Research in Counseling: A 10‐Year Review to Inform Practice

This study reviewed 4,457 articles from 1998 to 2007 in American Counseling Association division‐affiliated journals to identify research articles published in counseling; 1,139 articles (25.6%) were quantitatively research based. The authors provide details related to quantitative research publications, including individual journal contribution to the research base, focus areas for research, and independent and dependent variables highlighted by researchers. One summary finding was that only 6% of counseling research articles explored effectiveness of counseling interventions.
