Psychometric Evaluation of the Rage Outbursts and Anger Rating Scale in an Outpatient Psychiatric Sample

The primary objective of this study was to examine the psychometric properties of a measure of anger/rage attacks—the Rage Outburst and Anger Rating Scale (ROARS)—in a sample of youth (n = 81, ages 7–17 years, 72.8 % male) receiving treatment at an outpatient pediatric psychiatric clinic. A trained rater completed the ROARS and Clinical Global Impression-Rage (CGI-Rage). Children completed the Spence Children’s Anxiety Scale for Children and Center for Epidemiological Studies Depression Scale. Parents completed the Spence Children’s Anxiety Scale for Parents. Internal consistency (α = .89), inter-rater reliability (κ = .94) and 1-week test–retest reliability (r = .72) were calculated for the ROARS. The ROARS was correlated with CGI-Rage (r = .68, ρ < .001), although not with parent- and child-rated anxiety symptoms or with child-rated depressive symptoms. Implications regarding clinical utility of the ROARS and directions for future research are discussed.     

Multiple cue use and integration in pigeons (<Emphasis Type="Italic">Columba livia</Emphasis>)

Encoding multiple cues can improve the accuracy and reliability of navigation and goal localization. Problems may arise, however, if one cue is displaced and provides information which conflicts with other cues. Here we investigated how pigeons cope with cue conflict by training them to locate a goal relative to two landmarks and then varying the amount of conflict between the landmarks. When the amount of conflict was small, pigeons tended to integrate both cues in their search patterns. When the amount of conflict was large, however, pigeons used information from both cues independently. This context-dependent strategy for resolving spatial cue conflict agrees with Bayes optimal calculations for using information from multiple sources.     

Anthropocentric Rhetorical Discourse in Popular Science Writing about Human Evolution

Discourse describing evolution in contemporary popular science writing often posits that humans evolved not from an ape, but from a merely ape-like or generalized primate. Contemporary fossil and genetic evidence, though, have revealed what can accurately be described as an extinct ape species as ancestral to the human lineage. The persistence of ambiguous terms in popular science writing may be interpreted as a form of anthropocentric rhetorical discourse. Nonetheless, while such discourse is often justified in terms of increasing the public understanding of science, it may also mitigate (whether consciously intended or not) religion-based resistance to evolutionary theory.     

Rational Thinking Promotes Suspect‐friendly Legal Decision Making

Judges, juries, and other legal decision makers are frequently obligated to find facts about an alleged crime. Does this fact finding benefit from purely rational decision making or from a more intuitive approach? In three studies, rationality was found to be related to more suspect‐lenient decision making. The data suggest that fact finding in criminal proceedings is served best with strictly rational analyses of the evidence, rather than with intuition, gut feeling, and other obscure decision processes.Copyright © 2015 John Wiley & Sons, Ltd.     

Similarity to the self influences cortical recruitment during impression formation

Prior work has shown that whether or not someone is similar to the self influences person memory—a type of self-reference effect for others. In this study, we were interested in understanding the neural regions supporting the generation of impressions and subsequent memory for targets who vary in similarity to the self. Participants underwent fMRI scanning while forming positive or negative impressions of face–behavior pairs. We tested participants’ memory for their generated impressions and then back-sorted the impression trials (encoding) into different levels of self-similarity (high, medium, low) using a self-similarity posttest that came after recognition. Extending prior behavioral work, our data confirmed our hypothesis that memory would be highest for self-similar others and lowest for self-dissimilar others. Dorsal anterior cingulate cortex (dACC) activity increased with self-similarity (high > medium > low) to targets, regardless of later memory for them. An analysis of regions supporting impression memory revealed a double dissociation within medial temporal lobe regions: for similar others, amygdala recruitment supported memory, whereas for dissimilar others, hippocampal activation supported memory. These results suggest that self-similarity influences evaluation and memory for targets but also affects the underlying neural resources engaged when thinking about others who vary in self-similarity.     

Criteria Based Content Analysis: The Less Scientific Road to Truth

Criteria Based Content Analysis (CBCA) is a forensic tool that aims atdistinguishing true from false statements made by crime victims. As such,CBCA and similar techniques are regularly employed by psychologicalexpert-witnesses in court. However, it could be argued that the diagnosticaccuracy of CBCA is moderate, and too low for application in the forensiccontext. The current article discusses problems that arise if conclusionsabout credibility of testimonies based on CBCA are presented in court. Afundamental, yet so far hardly addressed flaw is that CBCA suffers from aninherent truth bias. That is, the underlying notion that credibility isexamined by means of searching for signs supporting truthfulness isscientifically less valid than the approach in which credibility isestablished by focusing on alternative explanations and signs of deceit.     

Cognitive adaptation and its consequences: a test of cognitive continuum theory

Cognitive Continuum Theory (CCT) is an adaptive theory of human judgement and posits a continuum of cognitive modes anchored by intuition and analysis. The theory specifies surface and depth task characteristics that are likely to induce cognitive modes at different points along the cognitive continuum. The current study manipulated both the surface (information representation) and depth (task structure) characteristics of a multiple‐cue integration threat assessment task. The surface manipulation influenced cognitive mode in the predicted direction with an iconic information display inducing a more intuitive mode than a numeric information display. The depth manipulation influenced cognitive mode in a pattern not predicted by CCT. Results indicate this difference was due to a combination of task complexity and participant satisfacing. As predicted, analysis produced a more leptokurtic error distribution than intuition. Task achievement was a function of the extent to which participants demonstrated an analytic cognitive mode index, and not a function of correspondence, as predicted. This difference was likely due to the quantitative nature of the task manipulations. Copyright © 2000 John Wiley & Sons, Ltd.
