A note on partitioned determinants

A formula for the determinant of a partitioned matrix, possibly with singular submatrices, is derived and applied to some psychometric and numerical problems.     

Generalized eigenvalue problems with positive semi-definite matrices

In a recent paper in this journal McDonald, Torii, and Nishisato show that generalized eigenvalue problems in which both matrices are singular can sometimes be solved by reducing them to similar problems of smaller order. In this paper a more extensive analysis of such problems is used to sharpen and clarify the results of McDonald, Torii, and Nishisato. Possible extensions are also indicated. The relevant mathematical literature is reviewed briefly.     

Psychophysiological effects of noxious imagery: Prevalence and prediction

Research suggests that people who generate psychophysiological arousal in emotive imagery therapies are likely to show the largest therapeutic gains. This study investigated the frequency of occurrence and methods of predicting this imagery skill. The effects of five fearful imagery themes on 95 undergraduate volunteers were evaluated in individual sessions by psychophysiological (SRL, EKG and EMG), self-report (anxiety and clarity ratings) and behavioral (motoric expression) measures. Additionally, four questionnaires (Betts, Gordon, APQ and STAI) were administered in a group session. EKG arousal occurred in 66% of our subjects, SRL arousal in 38% and EMG arousal in 16%. Only 9% of our subjects experienced arousal in all three psychophysiological responses and 24% experienced arousal in neither. Motoric expression (overt behavioral emoting) best predicted psychophysiological arousal, self-report ratings were a distant second, and the questionnaires were worthless in this regard. Imagery-induced psychophysiological arousal appears to be a fairly common phenomena, though it eludes convenient prediction. Some training strategies were discussed, (response proposition instructions, biofeedback and motoric coaching), which could be employed with persons deficient in psychophysiological imagery skills prior to their commencing an emotive imagery therapy.     

Self-image formation in adopted children: The environment within

Adoption of a child is an event in which a number of crises have converged. Both the biologic and adoptive families have contributed their failures and crises, and the subsequent interpretations of these by the adopted child can lead to polarized themes of goodness and badness. The absence of the biologic parents and of a coherent history reinforces the tendency to splitting. This paper explores these operations and raises questions about prevailing adoption practices.Paper presented at Spence-Chapin Symposium on Identity Problems of Children in Non-Nuclear Families, April 11, 1981.     

Choice,consciousness and ideological language

Because psychotherapists are not moral teachers, they ought not to advise their clients about evaluative questions. This means that their advice must be limited to a concern with the client's view of reality. It happens that in our times, there are prefabricated views of reality on offer from a variety of ideologies-Marxism and feminism being currently the most influential. Ideologists not only offer prefabricated realities-called consciousness- but also present a set of arguments to show that because choice is unreal, consciousness is all that matters. Adopting the ideological concept of consciousness thus becomes a backdoor variant of the ultimate sin against scientific method: namely smuggling unsubstantiated, indeed undiscussed, values into therapy.     

The role of imagery in the representation of linear orderings

Two experiments were carried out to investigate whether visual imagery was used in representing transitive linear ordering relationships. Subjects were presented with passages describing either a linear ordering or a set inclusion relationship, while being subjected to either visual or verbal interference. Performance was tested by asking subjects to judge the truth or falsity of statements concerning both the information presented in the passages and inferences that could be drawn from this information. In neither experiment was there any evidence for the linear ordering material being selectively disrupted by the visual interference task, as would have been predicted by the imagery theory. Thus it is concluded that linear orderings are probably not represented as visual images.     

The Primary Mental Health Project (PMHP): Evaluation of current program effectiveness

This study evaluated the effectiveness of the Primary Mental Project (PMHP), a program for early detection and prevention of school adjustment problems. Pre- and postprogram assessments were done with 215 primary-grade children seen in PMHP, usig teacher ratings of problem behaviors and competencies, and child-aide ratings of problems. School mental health professionals judged educational and behavioral changes in project children during the year. Significant across-the board improvements were found on all criterion measures. Modest intercorrelations among criterion change estimates suggested that the observed changes were due to program, rather than halo, effects. PMHP children also improved significantly more than matched, retrospective controls.     

The role of dissimulation and social desirability in the measurement of moral reasoning

A series of studies investigating the psychometric and conceptual properties of the Survey of Ethical Attitudes (SEA), a paper-and-pencil measure of moral reasoning, is reported. The results of these studies indicate that the scale is clearly susceptible to the influence of response dissimulation in the form of both role-playing and impression management, and is also confounded with sources of stylistic variance in the form of social desirability. Previous proposals concerning the relationships among moral development, moral reasoning, and personality structure are reviewed in light of these findings, and an alternative conceptualization of the measure in terms of political and social attitudes is offered.     

The effects of alcohol and extreme provocation on the use of a highly noxious electric shock

Intoxicated and nonintoxicated subjects were given the opportunity to administer a potentially injurious level of shock to an opponent who behaved in either a provocative or an extremely provocative manner. The provocative opponent attempted to administer high-intensity shocks to the subject. The extremely provocative opponent attempted to administer high-intensity shocks and the potentially injurious level of shock. The intoxicated subjects in the extreme provocation condition evidenced the greatest increase in the use of the potentially injurious shock. It was concluded that aggression is a function of the interaction of alcohol consumption and level of provocation.
