Information Integration Theory,Juror Bias,and Sentence Recommendations Captured Over Time in a Capital Trial

Initial juror verdicts have been shown to predict final verdicts, leading researchers to conclude that jurors seek confirmatory information during trial (confirmation bias) or distort information to fit pre‐existing biases (pre‐decisional distortion). However, Information Integration Theory suggests that individuals are not distorting/ignoring this information, and instead, information influences judgments in the direction of the message. The current study sought to test these competing theories in a juror setting. Mock jurors were presented with the sentencing phase of a capital trial and were asked to give sentence recommendations at eight different time points. Additionally, they were grouped by their pretrial bias as being pro‐defense, neutral, or pro‐prosecution. Results showed support for Information Integration Theory; although jurors' pretrial bias predicted final sentence, sentence recommendations were affected in the direction of the testimony presented throughout the trial (e.g., pro‐defense testimony lowered death penalty decisions across all groups). Implications and future directions are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Anxiety Symptoms in African American Children: Relations with Ethnic Pride,Anxiety Sensitivity,and Parenting

This cross-sectional study examined the relations among children’s ethnic pride, perceived parenting behavior (i.e., parental control, parental acceptance), anxiety sensitivity, and child anxiety symptoms (i.e., physical symptoms, social anxiety symptoms, separation anxiety symptoms, and harm avoidance symptoms) in 266 African American school children (M = 9.98 years old; 55% girls). Structural equation modeling results indicated that high ethnic pride was associated with high parental acceptance. High perceived parental acceptance, in turn, was related to children reporting low levels of social anxiety symptoms and high levels of harm avoidance. In addition, high parental control was related to high anxiety sensitivity. Anxiety sensitivity partially mediated the relation between parental control and separation anxiety symptoms, such that parental control was both directly and indirectly related to separation anxiety symptoms. Parental control was indirectly related to physical symptoms, social anxiety symptoms, and harm avoidance symptoms through its direct link to anxiety sensitivity. The study’s results increment knowledge about factors influencing specific dimensions of anxiety in African American children.     

The neural basis of illusory gustatory sensations: two rare cases of lexical-gustatory synaesthesia

Lexical-gustatory synaesthesia is a rare phenomenon in which the individual experiences flavour sensations when they read, hear, or imagine words. In this study, we provide insight into the neural basis of this form of synaesthesia using functional neuroimaging. Words known to evoke pleasant, neutral, and unpleasant synaesthetic tastes and synaesthetically tasteless words were presented to two lexical-gustatory synaesthetes, during fMRI scanning. Ten non-synaesthetic participants were also scanned on the same list of words. The synaesthetic brain displayed a different pattern of activity to words when compared to the non-synaesthetes, with insula activation related to viewing words that elicited tastes that have an associated emotional valence (i.e., pleasant or unpleasant tastes). The subjective intensity of the synaesthesia was correlated with activity in the medial parietal lobes (precuneus/retrosplenial cortex), which are implicated in polymodal imagery and self-directed thought. This region has also previously been activated in studies of lexical-colour synaesthesia, suggesting its role may not be limited to the type of synaesthesia explored here.     

Openness to Experience and Intellect Differentially Predict Creative Achievement in the Arts and Sciences

The Big Five personality dimension Openness/Intellect is the trait most closely associated with creativity and creative achievement. Little is known, however, regarding the discriminant validity of its two aspects—Openness to Experience (reflecting cognitive engagement with perception, fantasy, aesthetics, and emotions) and Intellect (reflecting cognitive engagement with abstract and semantic information, primarily through reasoning)—in relation to creativity. In four demographically diverse samples totaling 1,035 participants, we investigated the independent predictive validity of Openness and Intellect by assessing the relations among cognitive ability, divergent thinking, personality, and creative achievement across the arts and sciences. We confirmed the hypothesis that whereas Openness predicts creative achievement in the arts, Intellect predicts creative achievement in the sciences. Inclusion of performance measures of general cognitive ability and divergent thinking indicated that the relation of Intellect to scientific creativity may be due at least in part to these abilities. Lastly, we found that Extraversion additionally predicted creative achievement in the arts, independently of Openness. Results are discussed in the context of dual‐process theory.     

Changes in behavior and behavioral intentions among middle-age women: results from an osteoporosis prevention program

The purpose of this study was to evaluate changes in behaviors and behavioral intentions that occurred among 342 middle-age women (M age 49.5 yr.) after participating in an Osteoporosis Prevention Program. The valid and reliable Osteoporosis Preventing Behaviors Survey (developed by Doheny and Sedlak) and a survey developed for this work were measures. Significant changes in behaviors were reported, especially increases in weight-bearing physical activity, dairy product intake, and decreases in consumption of caffeine-containing beverages. Many subjects reported intentions to increase physical activity and calcium intake. An Osteoporosis Prevention Program may help promote osteoporosis prevention behaviors, but intents must be followed up to check actual change.     

Psychometric properties of the life events checklist

The Life Events Checklist (LEC), a measure of exposure to potentially traumatic events, was developed at the National Center for Posttraumatic Stress Disorder (PTSD) concurrently with the Clinician Administered PTSD Scale (CAPS) to facilitate the diagnosis of PTSD. Although the CAPS is recognized as the gold standard in PTSD symptom assessment, the psychometric soundness of the LEC has never been formally evaluated. The studies reported here describe the performance of the LEC in two samples: college undergraduates and combat veterans. The LEC exhibited adequate temporal stability, good convergence with an established measure of trauma history -- the Traumatic Life Events Questionnaire (TLEQ) -- and was comparable to the TLEQ in associations with variables known to be correlated with traumatic exposure in a sample of undergraduates. In a clinical sample of combat veterans, the LEC was significantly correlated, in the predicted directions, with measures of psychological distress and was strongly associated with PTSD symptoms.     

Simulating murder: the aversion to harmful action

Diverse lines of evidence point to a basic human aversion to physically harming others. First, we demonstrate that unwillingness to endorse harm in a moral dilemma is predicted by individual differences in aversive reactivity, as indexed by peripheral vasoconstriction. Next, we tested the specific factors that elicit the aversive response to harm. Participants performed actions such as discharging a fake gun into the face of the experimenter, fully informed that the actions were pretend and harmless. These simulated harmful actions increased peripheral vasoconstriction significantly more than did witnessing pretend harmful actions or to performing metabolically matched nonharmful actions. This suggests that the aversion to harmful actions extends beyond empathic concern for victim harm. Together, these studies demonstrate a link between the body and moral decision-making processes.     

The education of attention as explanation of variability of practice effects: learning the final approach phase in a flight simulator

The present study reports two experiments in which a total of 20 participants without prior flight experience practiced the final approach phase in a fixed-base simulator. All participants received self-controlled concurrent feedback during 180 practice trials. Experiment 1 shows that participants learn more quickly under variable practice conditions than under constant practice conditions. This finding is attributed to the education of attention to the more useful informational variables: Variability of practice reduces the usefulness of initially used informational variables, which leads to a quicker change in variable use, and hence to a larger improvement in performance. In the practice phase of Experiment 2 variability was selectively applied to some experimental factors but not to others. Participants tended to converge toward the variables that were useful in the specific conditions that they encountered during practice. This indicates that an explanation for variability of practice effects in terms of the education of attention is a useful alternative to traditional explanations based on the notion of the generalized motor program and to explanations based on the notions of noise and local minima.     

Reference group data for the Reitan-Indiana Neuropsychological Test Battery for Young Children

This study presents a data set for a reference group on the Reitan-Indiana Neuropsychological Test Battery for Young Children. The data set is based on a sample of 224 children, ages 5 to 8 years, referred to a special services cooperative for academic or behavioral concerns during the years 1980 through 1993. Data are presented in terms of sample size, means, standard deviations, diagnostic classifications, and population characteristics. Previously published data sets are reviewed in comparison to this newly acquired data set. Potential advantages of this data set include the larger sample, contemporary data collection, and a sample drawn from a United States school-referred population.
