Paradigms and crises in psychoanalysis

The use of T. S. Kuhn's Structure of Scientific Revolutions as a model for the history of psychoanalysis is addressed. It is shown that his categories have been regularly misapplied in the interest of establishing the scientific status of psychoanalysis, or of proposing a new theoretical structure. It is argued that Kuhn's model may nevertheless be useful for the history of psychoanalysis on condition that its categories are used precisely, and their correspondence to the data is tested rather than assumed.     

The psychological precipitants of transient postpartum depression: A review

Studies reporting incidence rates for the “postpartum blues” (defined as atransient depressive episode occurring in the first 10-14 days after childbirth) are surveyed, and the methodological issues involved in collecting these data are considered. When women provide self-report ratings of depression on each day in the first postpartum week, the incidence of the blues is about 66%. Psychological factors found to be associated with the blues include a history of psychiatric disturbance or depression during pregnancy, menstrual distress, and a trouble-free pregnancy. Other factors not shown to be related to the blues include maternal age, socioeconomic status, prenatal anxiety, method of feeding, and whether the pregnancy was wanted. There is no evidence concerning the effect of the blues on maternal attachment, and the relationship between the blues and postpartum depression is unclear. There is discussion of the significance of the blues as a measure of the effectiveness of antenatal preparation and adjustment to the crisis of childbirth.     

Child custody disputes: A review of legal and clinical resolution methods

This paper reviews existing practices from the mental health, marriage and family therapy, and legal professions which offer alternatives to traditional adversarial custody resolution methods. Based upon suggestions from legal and mental health professionals, the authors advocate allocating state resources for interprofessional family courts which would provide custody counseling, mediation, evaluation, and consultation as alternatives to adversarial methods.     

Inferring decay in short-term memory: The issue of capacity

Experiments examining the issue of decay in short-term memory have assumed a single undifferentiated source of processing capacity which cannot be devoted to rehearsal when consumed in the processing of a nonverbal interpolated task. Three experiments reported here call this logic into question, since variations in difficulty in the nonverbal interpolated task failed to affect recall. Slight forgetting produced by a nonverbal interpolated task, relative to a no interpolated task control, was attributed to qualitative differences from performing two tasks simultaneously rather than only one. Results from the third experiment indicated that retrieval after a period of nonverbal interpolated activity is from primary rather than secondary memory.     

Speed-accuracy tradeoff in double stimulation: II. Effects on the second response

In the double-stimulation paradigm subjects respond to two successive stimuli. Previous research (Knight & Kantowitz, 1974) showed that a subject's speed-accuracy tradeoff (SAT) strategy interacted with the interval between the two stimuli to determine response performance to the first stimulus. The present experiment examined the influence of SAT strategy on response performance to the second stimulus. Interest focused on effects of SAT strategy upon the psychological refractory period (PRP) effect. If a single mechanism underlies beth first-and second-response performance (e.g., the PRP effect) in double stimulation, effects of SAT upon the second response should be similar to effects upon the first response. Results showed that the PRP effect appeared only when second-response accuracy was stressed. Under speed emphasis double-stimulation second-response latency never exceeded a single-stimulation baseline. This was analogous to first-response latency effects found by Knight and Kantowitz (1974). Response grouping was strongly influenced by SAT strategy and two response-grouping mechanisms were distinguished. Implications of these and interresponse time data for models of double-stimulation performance are discussed.     

Speed-accuracy tradeoff in double stimulation: Effects on the first response

A single-stimulation and two double-stimulation response conditions were compared using explicit payoff matrices to vary speed-accuracy tradeoff. Under accuracy payoff, response latency (RT(1)) to the first stimulus increased as ISI dropped but accuracy remained high and relatively constant. Under speed payoff, RT(1) was only slightly affected by ISI but accuracy dropped as ISI decreased. Transmitted information rates consistently reflected detrimental effects of short ISI. In double stimulation, but not in single stimulation, error response latency exceeded correct response latency. Furthermore, error response latencies were found to be far more variable and more sensitive to changes in speed-accuracy condition than were correct response latencies. Finally, under both speed and accuracy conditions, response latency to the first of two successive stimuli was faster if a response was also required to the second stimulus. Implications of the data for possible models of double-stimulation speed-accuracy tradeoff are considered.     

An experiment control computer system time shared by several laboratories

An experiment control computer system, operational for more than 2 years, is discussed. The system is multiprogammed, using a vendor supplied real-time operating system. Individual experiments employ multitasking—fast response functions are implemented in core resident tasks while interactive and other slow response functions are implemented in tasks that operate under time sharing. The areas of psychological research currently supported are concept formation studies, EEG evoked response studies, monitoring the autonomic nervous system, perception studies, and family interaction studies.     

Social motives among Anglo American and Mexican American children: Experimental and projective measures

The measurement approaches to social motives, cooperation-competition games and projective tests, have revealed apparently similar findings: Anglo American children are more competitive and higher in n Achievement compared to Mexican American children, who are more cooperative and higher in n Affiliation. The present experiment tested the extent to which (1) competitiveness is related to n Achievement, (2) cooperativeness is related to n Affiliation, and (3) the cultural differences in cooperation-competition are related to those in n Affiliation and n Achievement. Results indicate that social motives inferred from a cooperation-competition game have a meaningful relation to those inferred from a projective test, but that the cultural differences in cooperation-competition are larger and are not explained by cultural differences in n Affiliation and n Achievement. Social motives inferred from each measurement methodology, while somewhat related, are distinct.
