Repeatedly Thinking about a Non-event: Source Misattributions among Preschoolers

In this paper we review the factors alleged to be responsible for the creation of inaccurate reports among preschool-aged children, focusing on so-called "source misattribution errors." We present the first round of results from an ongoing program of research that suggests that source misattributions could be a powerful mechanism underlying children′s false beliefs about having experienced fictitious events. Preliminary findings from this program of research indicate that all children of all ages are equally susceptible to making source misattributions. Data from a follow-up wave of data indicate that very young children may be disproportionately vulnerable to these kinds of errors when the procedure is changed slightly to create mental images more easily. This vulnerability leads younger preschoolers, on occasion, to claim that they actually experienced events that they only thought about. These preliminary findings are discussed in the context of the ongoing debate over the veracity and durability of delayed reports of early memories, repressed memories, dissociative states, and the validity risks posed by therapeutic techniques that entail repeated visually guided imagery inductions.     

Trait Influences on Stress Appraisal and Coping: An Evaluation of Alternative Frameworks

According to contemporary trait models, personality variables influence the relation of certain social-cognitive processes to coping and adjustment. Specifically, neuroticism may effect a greater perception of threat in a given stressor and thus effect a greater propensity for emotion-focused coping efforts. Similarly, higher levels of conscientiousness may be related to a greater use of problem-focused coping. We tested these presumed effects of personality traits on the association between stress appraisals and coping among 141 undergraduates. Resulting models indicated that certain personality characteristics are related to appraisal and coping activities, but these relations do not fully explain the association between stress appraisal and coping.     

Automated 3-D tracking of video-captured movement using the example of an aquatic mollusk

We describe a computer program that tracks the three-dimensional coordinates of a snail (moving within a tank) from images captured by a single video camera. The tank and a mirror placed at 45° to one side are viewed to provide direct and reflected images of a pond snail,Lymnaea stagnalis, moving around the tank. The output of the camera is captured with an IBM-compatible PC using a frame-grabbing VideoBlaster board. The main features of our Windows program is the frame-by-frame analysis of the captured video, enhancement of contrast, location of dark “snails,” discrimination by size, trigonometric determination of thex, y, z coordinates, and the final export of data in a spreadsheet-ready format. After the user has outlined the position of the tank on the screen and set the discrimination thresholds, no further user activity is required. This makes the analysis of slowly moving mollusks much less operator intensive and less tedious. The method is applicable to other faster moving organisms (e.g., fish) because the analysis is performed on captured video sequences.     

Asymmetries in the spatial localization of transformed targets

This study was designed to examine the contribution of the right cerebral hemisphere in the spatial localization of visual targets for manual aiming. Visual targets were briefly presented to the right and left fields and subjects were required to point either to the target location, or a "mirror" image of the target location with their right or left index finger. Whereas reaction times were faster for left-hand pointing than for right-hand pointing, there was no differential effect of the mirror image transformation. This suggests that left-hand reaction time advantages are more related to right hemisphere involvement in the spatial parameterization of the movement than spatial localization of the target.     

Divorce in the kibbutz: Affective responses to separation

This article is part of a comprehensive research project in which the central characteristics of the process of divorce in the kibbutz were examined. It appears that the framework of the kibbutz, free as it is from socio-economic pressures and boundary factors not directly connected with the marital relationship as such, provides an excellent and perhaps unique opportunity to investigate the pure emotional effects of the marital breakup.     

Rationale and directions for an increased emphasis on the therapeutic relationship in family therapy

This paper argues the need for an increased emphasis on the therapeutic relationship in family therapy. The ways in which the field of family therapy has eschewed the importance of the therapeutic relationship are discussed. Therapeutic alliance research from the field of individual psychotherapy and research on the importance of relationship factors to family therapy are reviewed. Suggestions for family therapy theory, practice, and research are presented.An earlier version of this article was presented at the 1992 Western Canadian Conference on Family Practice.     

A gender-informed model of couple and family therapy: Relationship enhancement therapy

The key elements of gender-informed couple therapy are discussed with an emphasis on the significance of empathy and dialogue and the structuring of a context in which both can occur. Relationship Enhancement therapy, a psycho-educational and client-centered approach developed by Guerney (1977) is described and illustrated as one method of operationalizing a constructivist-systemic approach to couple therapy in which a conversation toward profound changes in gender relationships can take place.     

Myths of brief family therapy task intervention

The steps of brief treatment promoted by Watzlawick, Weakland and Fisch (1974) and Haley (1976, 1987) elude the novice family practitioner, especially in deriving end-of-the session task interventions from earlier assessment. The gap between the suggested procedure and the beginning clinician's results is just starting to surface in brief therapy research. This paper compares the above authors' interactional and problem-solving approaches, contextualizing their theories in light of training issues emerging from preliminary research. The ensuing myths of brief family therapy task intervention typically espoused by the neophyte are thus demystified, making what experience teaches more accessible.
