Data transfer concepts and strategies in a psychological research environment

In this paper, we discuss the importance and problems of data transfer in psychological research environments. Discussion includes how simple text file transfer systems meet researchers’ needs. The systems’ shortcomings are also analyzed. Strategies for customizing systems, using pre-prepared software packages, point-to-point systems, and “networked” systems, are carefully analyzed.     

Lotus 1-2-3 simulation of frequency encoding on the basilar membrane

A spreadsheet simulation was designed to describe frequency encoding on the basilar membrane according to the place theory (Greenwood, 1961). For any given frequency, the simulation displayed the location of maximum amplitude on the basilar membrane and the relevant critical bandwidth. The authors found a very high correlation between data given by the simulation and data from empirical research. The high correlation indicates the validity of the place theory of frequency encoding and the usefulness of this simulation for future research purposes.     

Hinton diagrams: Viewing connection strengths in neural networks

A graphical analysis similar to that used by Hinton and Shallice (1991) was applied to the hair cells of a simulated auditory transducer. The graphical analysis made it apparent that there were hair cells that responded to a narrow range of frequencies, as would be predicted by the tonotopic organization of the real physiology. In short, this study demonstrates the efficacy of using graphic techniques to examine the nature of the autopoetic organization of the hidden layer of back-propagation networks.     

Word associations and the development of lexical memory

Endel Tulving's distinction between “episodic” and “semantic” memory defines changes with age in word association norms in a more informative and more comprehensive manner than the syntactic classifications normally used. The principal development as subjects mature is an episodic-semantic shift. Young children associate primarily to the stimulus's perceived contexts, older subjects to its abstract semantic content.     

Computer-managed inferential statistical analysis of EEG data

Much of the neuroelectrical/psychophysiologic research of the past has involved the use of “group-type” statistics. Often, this has resulted in large variances that make it difficult, if not impossible, to find significant differences. Using the INNOVATE technique of single-subject design, we are able to consistently demonstrate significant differences in EEG spectra related to experimental and clinical effects previously masked.     

Trust differences between supervisors and subordinates: Examining the role of race and gender

This study examined trust differences between supervisor and subordinate dyads that differ in race or gender as well as in dyads that were similar. The results of 301 (the sample consisted of 241 whites and 41 blacks, 216 were women and 86 were men) respondents indicated gender and race do affect trust. More specifically, the highest level of trust was found between female subordinates reporting to male supervisors. It was also found that whites reporting to whites perceived significantly less trust than blacks reporting to blacks, but significantly greater trust than whites reporting to blacks. The results also indicated that whites reporting to blacks and blacks reporting to whites perceive significantly less trust than blacks reporting to blacks. A discussion of these results is also included.     

Matrix manipulation and interpretation of data related to AIDS transmission

This research describes how a currently available spreadsheet program can be set up to analyze sociographic data. An algorithm developed by Jamrich (1960) is presented, along with both the mathematical and the spreadsheet equations. An example of the application of the algorithm and equations to AIDS transmission data is presented.     

Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence

This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness.     

"Pray for those who mistreat you": effects of prayer on anger and aggression

Although some religious teachings have been used to justify aggression, most religious teachings promote peace in human affairs. Three experiments tested the hypothesis that praying for others brings out the more peaceful side of religion by reducing anger and aggression after a provocation. In Experiment 1, praying for a stranger led provoked participants to report less anger than control participants who thought about a stranger. In Experiment 2, provoked participants who prayed for the person who angered them were less aggressive toward that person than were participants who thought about the person who angered them. In Experiment 3, provoked participants who prayed for a friend in need showed a less angry appraisal style than did people who thought about a friend in need. These results are consistent with recent evolutionary theories, which suggest that religious practices can promote cooperation among nonkin or in situations in which reciprocity is highly unlikely.
