Attentional biases in geometric form perception

This paper reports the operation of robust attentional bias to the top and right during perception of small, single geometric forms. Same/different judgements of successively presented standard and comparison forms are faster when local differences are located at top and right rather than in other regions of the forms. The bias persists when form size is reduced to approximately one degree of visual angle, and it is unaffected by saccadic eye movements and by instructions to attend to other reliably differentiating regions of the forms. Results lend support in various degrees to two of the possible explanations of the bias: (1) a static, skewed distribution of attentional resources around eye fixation; and (2) biased, covert scanning that commences invariably at the top and right of stim ulus forms. Origins of the bias in terms of possible left-hemispheric capacity for constructing representations of visual stimuli from parts, as well as in terms of reading experience and prevailing optic flow during locomotion through space are considered. Recent investigations of conditions under which the bias can be maintained or reduced are mentioned.     

Beyond cognitive ability: Improving the prediction of performance

New measures of practical intelligence and personality traits were assessed for their ability to improve the prediction of performance beyond cognitive ability. Measures of practical intelligence from the newly developed Constructive Thinking Inventory and traits measuring emotional stability and expedience were used as independent variables in regression analyses predicting academic performance, training performance and leadership ratings of 86 student leaders. The constructive thinking scales added significantly to the prediction of academic performance, beyond measures of cognitive ability. Constructive thinking also accounted for unique variance predicting training performance and leadership ratings. Personality traits were unrelated to performance or leadership.     

Marital adjustment among rural couples: The role of expressiveness

This study examined the relationship between marital adjustment and husbands' and wives' instrumentalness and expressiveness. Eighty-five rural couples completed the Spanier Dyadic Adjustment Scale and the Personal Attributes Questionnaire. Multiple regression analyses indicated that husbands' expressiveness was the sole predictor of both husbands' and wives' marital adjustment. Results are compared to previous research findings with urban couples. Implications of the findings for gender-related patterns of socialization are also discussed.     

Resetting the pitch-analysis system: 1. Effects of rise times of tones in noise backgrounds or of harmonics in a complex tone

The question of whether sudden increases in the amplitude of pure-tone components would perceptually isolate them from a more complex spectrum was investigated in two experiments. In Experiment 1, a 3.5-sec noise was played as a masker. During the noise, two pure-tone components of different frequencies appeared in succession. Subjects were asked to judge whether the pitch sequence went up or down. The rise time of these components had only a small and inconsistent effect on discrimination. In Experiment 2, the 3.5-sec background signal was a complex tone. The amplitudes of two of its components were incremented in succession. Again, subjects judged whether the pitch pattern went up or down. This time there was a sizable, monotonic effect of the rise time of the increments, with more rapid increments leading to better discrimination. The difference between the two results is interpreted in terms of the auditory system’s response to changing and unchanging signals and the role of its “sudden-change” responses in attracting perceptual processing to certain spectral regions.     

An evaluation of parents as behavior change agents in the Preschool Life Skills program

Parental involvement in intervention can support intervention efficacy, improve generalization, and increase accessibility. The Preschool Life Skills (PLS) program is designed to teach 13 preschool life skills and prevent problem behavior. The current study explores the utility of the PLS program as delivered by parents. In Experiment 1, 6 parents were taught to use the PLS program at home with their typically developing children (3 years 3 months to 4 years 11 months). This application of the PLS program led to an increase in preschool life skills and a decrease in problem behavior and supported some generalization of the target preschool life skills from the home to preschool settings. In Experiment 2, 7 parents were taught to use the PLS program with their children with autism spectrum disorder (ASD; 3 years 11 months to 6 years 9 months). Results overall supported the parent implementation of the program and highlighted modifications required to support positive outcomes for children with ASD.     

Reliability of Pass and Fail Decisions on Tests Employing Cut Scores

The study evaluated the reliability of pass and fail classifications for several teacher certification tests. Since these tests are used in the context of a cut score to classify examinees as pass and fail, evaluating the accuracy and consistency of these classifications is important. The classification accuracy and consistency statistics were estimated using the RELCLASS software. Results indicated the following. (1) The 29 teacher certification tests that were examined had a relatively high classification accuracy (0.827 to 0.999) and consistency (0.760 to 0.999). (2) Both classification accuracy and consistency increased as the difference between the mean and cut score increased. (3) Classification accuracy and consistency was higher for multiple-choice (MC) as compared to tests consisting of only constructed-response (CR) items or a combination of CR and MC items.     

Measuring anxious responses to predictable and unpredictable threat in children and adolescents

Research has highlighted the need for new methods to assess emotions in children on multiple levels to gain better insight into the complex processes of emotional development. The startle reflex is a unique translational tool that has been used to study physiological processes during fear and anxiety in rodents and in human participants. However, it has been challenging to implement developmentally appropriate startle experiments in children. This article describes a procedure that uses predictable and unpredictable aversive events to distinguish between phasic fear and sustained anxiety in children and adolescents. We investigated anxious responses, as measured with the startle reflex, in youths (N = 36, mean age = 12.63 years, range = 7-17) across three conditions: no aversive events (N), predictable aversive events (P), and unpredictable aversive events (U). Short-duration cues were presented several times in each condition. Aversive events were signaled by the cues in the P condition but were presented randomly in the U condition. Participants showed fear-potentiated startle to the threat cue in the P condition. Startle responses were also elevated between cues in the U condition compared with the N condition, suggesting that unpredictable aversive events can evoke a sustained state of anxiety in youths. This latter effect was influenced by sex, being greater in girls than in boys. These findings indicate the feasibility of this experimental induction of the startle reflex in response to predictable and unpredictable events in children and adolescents, enabling future research on interindividual differences in fear and anxiety and their development in youths.     

Would I lie to you? “leakage” in deceptive facial expressions relates to psychopathy and emotional intelligence

This was the first investigation of individual differences in adopting deceptive universal emotional expressions. We hypothesized that psychopathic traits would lead to a heightened ability to suppress emotional expressions and exhibit less “leakage” of inconsistent emotions during deceptive displays. Further, we predicted that emotional intelligence (EI) would lead to a heightened ability to simulate emotional expressions. Participants (N = 100) viewed emotionally arousing (happy, sad, fearful, disgusting) images, responding to each with a genuine or deceptive expression. Each video frame (30/sec) was coded for emotion (in)consistent with the intended expression (365,550 frames coded for 2437 expressions). As predicted, psychopathic traits - specifically, high levels of interpersonal manipulation - were related to shorter durations of unintended emotional “leakage” during deceptive expressions. In contrast, the erratic lifestyle element of psychopathy predicted greater emotional inconsistency during deceptive displays. Individuals higher in EI - specifically, the ability to perceive and express emotion - feigned emotions more convincingly than others but were not more immune to emotional leakage.     

Teaching moral reasoning through gesture

Stem‐cell research. Euthanasia. Personhood. Marriage equality. School shootings. Gun control. Death penalty. Ethical dilemmas regularly spark fierce debate about the underlying moral fabric of societies. How do we prepare today's children to be fully informed and thoughtful citizens, capable of moral and ethical decisions? Current approaches to moral education are controversial, requiring adults to serve as either direct (‘top‐down’) or indirect (‘bottom‐up’) conduits of information about morality. A common thread weaving throughout these two educational initiatives is the ability to take multiple perspectives – increases in perspective taking ability have been found to precede advances in moral reasoning. We propose gesture as a behavior uniquely situated to augment perspective taking ability. Requiring gesture during spatial tasks has been shown to catalyze the production of more sophisticated problem‐solving strategies, allowing children to profit from instruction. Our data demonstrate that requiring gesture during moral reasoning tasks has similar effects, resulting in increased perspective taking ability subsequent to instruction.
