The relationship of hemispheric preference,as measured by conjugate lateral eye movements,to accuracy of emotional facial expression

This study investigated the relationship between hemispheric preference and communication accuracy of facial affect. Hemispheric preference was determined by rating conjugate lateral eye movements. Forty right-handed females were classified: 10 right-movers (left hemisphere preference), 15 left-movers (right hemisphere preference), and 15 bidirectionals (no hemispheric preference). Subjects were shown emotionally loaded slides portraying happiness, fear, and disgust and their videotaped facial expressions were independently rated for accuracy. It was predicted that negative emotions involved right hemisphere activity and negative affect involved left hemisphere activity. As expected, it was found that left-movers were significantly better than right-movers at nonverbally communicating disgust and fear; hemispheric preference was unrelated to expression of happiness. The accuracy scores of the bidirectionals generally fell in between those of the left-movers and those of the right-movers. The results were discussed in reference to the differential lateralization of positive and negative emotions.This study was conducted as a senior research project by the first author under the supervision of the second author.     

DISTANGLE: A FORTRAN program to analyze and simulate spacing behavior of animals

A FORTRAN IV program, DISTANGLE, was written to aid in analysis of orientation and spacing parameters among groups of animals within enclosures. The 700-statement program requires, as minimum input, individual animal identification, each animal’s X and Y coordinates on a grid basis, and each animal’s angle of orientation on a 360-deg basis. The program was designed to give versatility to the user. Input may be raw data from cards or simulated (random) observations generated by the program. The program calculates distances among group members and determines angle relationships among selected individuals. Frequency of nearest neighbor relationships, frequency of positioning of animals at locations within the enclosure, and movement distances are determined. DISTANGLE will determine the angles any two animals of a group would have to turn to be facing each other, regardless of their locations and/or orientations within the enclosure. The program permits analyses of spatial relationships among a maximum of 50 animals, either actual or simulated, per observation. Shape of enclosure can be either a square, a circle, or a triangle.     

Loose but normal: a semantic association study

An abnormal facilitation of the spreading activation within semantic networks is thought to under-lie schizophrenics' remote associations and referential ideas. In normal subjects, elevated magical ideation (MI) has also been associated with a style of thinking similar to that of schizotypal subjects. We thus wondered whether normal subjects with a higher MI score would judge "loose associations" as being more closely related than do subjects with a lower MI score. In two experiments, we investigated whether judgments of the semantic distance between stimulus words varied as a function of MI. In the first experiment, random word pairs of two word classes, animals and fruits, were presented. Subjects had to judge the semantic distance between word pairs. In the second experiment, sets of three words were presented, consisting of a pair of indirectly related, or unrelated nouns plus a third noun. Subjects had to judge the semantic distance of the third noun to the word pair The results of both experiments showed that higher MI subjects considered unrelated words as more closely associated than did lower MI subjects. We conjecture that for normal subjects high on MI "loose associations" may not be loose after all. We also note that the tendency to link uncommon, nonobvious, percepts may not only be the basis of paranormal and paranoid ideas of reference, but also a prerequisite of creative thinking.     

Family Empowerment as a Mediator between Family-Centered Systems of Care and Changes in Child Functioning: Identifying an Important Mechanism of Change

We investigated the associations among perceived fidelity to family-centered systems of care, family empowerment, and improvements in children's problem behaviors. Participants included 79 families, interviewed at two time points across a one-year period. Paired samples t-tests indicated that problem behaviors decreased significantly across a one-year period. Hierarchical multiple regressions indicated that both fidelity to family-centered systems of care and family empowerment independently predicted positive change in children's problem behavior over a one-year period. However, when family empowerment is entered first in the regression, the relationship between fidelity to family-centered systems of care and change in children's problem behavior drops out, indicating that family empowerment mediates the relationship between family-centered care and positive changes in problem behaviors. Consistent with other literature on help-giving practices, family empowerment appears to be an important mechanism of change within the system of care philosophy of service delivery. Implications for practice and staff training are discussed.     

Memory for emotionally arousing stimuli: a comparison of younger and older adults

The authors compared emotional memory in younger (aged 18-32 years) and older (aged 59-84 years) adults. Previous researchers who investigated the emotionmemory relationship in younger adults consistently showed that emotional arousal enhances memory for central detail. The present authors' goal was to determine whether a similar effect could be found with older adults. Younger and older adults viewed a series of 12 slides, accompanied by a taped narrative, that showed emotionally arousing or neutral scenes in the middle phase (Slides 5-8). Participants then completed recognition tests that were scored for central detail, peripheral detail, and gist. The results indicated that, although younger adults showed higher performance than older adults did, both groups showed increased memory for central detail. In contrast, the authors found no such enhancement for peripheral detail or gist in either group. These results indicated that the arousal manipulation produced a similar effect on memory in younger and older adults. Furthermore, these results were consistent with the notion of poststimulus elaboration, which is the continued processing of central detail after the termination of an arousing event.     

Consciousness,Trauma, and Health: A Cognitive Systems Response to Payne,Walsh, and Oman

Religion and cognitive science contribute complementary understandings of the human person, and an integrated perspective can bridge clinical, spiritual, and philosophical resources to facilitate healing and growth. Drawing upon cognitive science and systems theory, I respond to Richard Payne, Mary Walsh, and Doug Oman’s comments on my Mind, Brain, and the Elusive Soul (Graves 2008; Oman 2011; Payne 2011; Walsh 2011).
