A proximal change experiment testing two communication exercises with intimate partner violent men

This study tests the immediate impact of two interventions for intimate partner violent (IPV) men in affecting behavioral and emotional change during arguments with their partners. Couples with an abusive male partner (N = 100) discussed an area of conflict twice, interrupted by a brief intervention. Men were randomly assigned to receive (a) an editing-out-the-negative skills training, (b) an accepting influence skills training, or (c) a time-out. IPV men in both skills-training conditions showed greater decreases in aggressive feelings than IPV men in the time-out condition based on their self-report and observed affective behavior. Women also reported feeling less aggressive when their husbands were assigned to one of the skills-training conditions as compared to the control (time-out) condition. Results suggest that IPV men can learn to adopt new communication skills and that they do appear to have a positive impact on the emotional tone of their arguments. Clinically, communication skills training may be a useful addition to battering intervention programs, although these skills may need to be taught to both men and women involved in violent relationships.     

Toward A Typology Of Abusive Women: Differences Between Partner-Only And Generally Violent Women In The Use Of Violence

Based on previous typologies of domestically violent men ( Holtzworth-Munroe & Stuart, 1994 ), women who were referred to a treatment agency for abusive behavior  ( N = 52)  were categorized into two groups based on the breadth of their use of violence: Partner-Only (PO) and Generally Violent (GV). PO women were hypothesized to use reactive violence, for example, out of fear or in self-defense, whereas GV women were hypothesized to use instrumental violence, that is, in order to exert control. Self-defense was assessed in three different ways and convergent validity was demonstrated for these three new measures. GV women reported using instrumental violence more than PO women, in a variety of situations. GV women tended to report more traumatic symptoms than PO women, although they did not experience significantly more abuse. GV women were more likely to witness their mothers' physical aggression. Thus, we theorize that GV women have been socialized to believe that it is acceptable for women to use violence to resolve conflict. Trauma history and violent socialization should be addressed clinically.     

Sex differences in semantic language processing: a functional MRI study

Predictions based on two models of sex differences in cerebral organization of language were compared by examining fMRI patterns of 10 females and 9 males during a semantic processing task. Both groups displayed activation of left inferior frontal gyrus (IFG), left superior temporal gyrus (STG), and cingulate. Females, but not males, showed bilateral IFG and STG activation. Further analyses revealed females had less diffuse left activation and greater right posterior temporal and insula region activation than males. Results support both an interhemispheric and an intrahemispheric model of sex differences in language, suggesting that the models may not be mutually exclusive.     

Perception of dynamic information in static handwritten forms

Handwriting recognition presents a problem for most theories of letter perception. How do people accurately discriminate letters given the variability in handwritten forms? We propose that perceivers detect and capitalize on information relating to production inherent in the static trace of the handwritten letter. In an "implicit detection" task, subjects' ability to detect stroke direction in a series of handwritten characters was found to be influenced by the particular drawing method used to generate the stimuli. Similar results were obtained in an "explicit detection" task in which the subjects were asked to speculate on the drawing method used to generate the samples. Our findings suggest that perceivers are able to extract information relating to production from the static trace. We propose that they can then use this information in conjunction with their knowledge of a common production process, shared by both producers and perceivers, to aid character recognition.     

Effects of increased processing demands on age differences in working memory

Three studies investigated (a) the plausibility of the claim that increasing the processing demands in a memory task contributes to greater involvement of a central processor and (b) the effects of altering reliance on the central processor on the magnitude of age-related differences in working-memory tasks. In the first study, young adults performed versions of 2 tasks presumed to vary in the degree of reliance on the central processor. In the second and third studies, young and older adults performed versions of a computation-span task that were assumed to vary along a rough continuum of the amount of required processing. The results indicated that although a central processor appears to be involved when working-memory tasks require simultaneous storage and processing of information, age-related differences in working memory seem to be determined at least as much by differences in the capacity of storage as by differences in the efficiency of processing.     

A low-cost high-speed digital data acquisition and display system

A flexible and inexpensive data acquisition and display system based upon the KIM-1 microcomputer module is described. A simple signal-conditioning circuit and program are shown that will allow events to be counted at rates to 1,000/sec and stored in successive time bins. The program counts events from each of two event detectors and stores the count of each detector in an independent set of time bins. Up to 127 16-bit bins are available to each event detector and bin width can be varied from 1 msec to 1 min. A separate input can be used to time-lock data collection to a specific stimulus allowing poststimulus histograms or IRTs to be collected. The collected data can be sequentially displayed as a decimal number on a built-in LED display and stored for later analysis on an inexpensive audio cassette recorder.     

Models of consultation: Preferences of educational professionals at five stages of service

Three professional education groups (elementary school principals, special education teachers, and second-grade teachers from two school systems) were asked to rate their preference for four models of consultation as offered by school psychologists at each of five stages of the consultation process. Results indicate that there were no differences among the three professional education groups in their ratings of the models. However, there was a significant difference in the ratings given to each model, with the collaboration model receiving the highest rating. A model by stage interaction also was noted, a finding which suggests that consultation preference should not be considered a unidimensional concept. The implications of these results for the training and practice of school psychologists in the consultation role are discussed.     

A microprocessor control system and solid state interface for controlling electrophysiological studies of conditioning

This paper describes a microprocessor control system and solid state interface for controlling the apparatus in combined behavioral-electrophysiological studies of conditioning. The computer program, which is designed to control classical conditioning of the rabbit’s nictitating membrane response, provides the flexibility to control all conditioning parameters (e.g., interstimulus and intertrial intervals, trial type, and sequence of trial types) with only minor modifications. The system is free from artifacts that can distort electrophysiological recordings and can easily be modified to accommodate other behavioral paradigms in which electrophysiological responses are recorded.
