A controlled comparative investigation of psychological treatments for chronic sleep-onset insomnia

A sample of physician-referred chronic insomniacs was randomly allocated to either progressive relaxation, stimulus control, paradoxical intention, placebo or no treatment conditions. Treatment process and outcome were investigated in terms of mean and standard deviation (night to night variability) measures of sleep pattern and sleep quality. Only active treatments were associated with significant improvement, but the nature of treatment gains varied. In particular, stimulus control improved sleep pattern, whereas relaxation affected perception of sleep quality. All improvements were maintained at 17 month follow-up. Results are discussed with reference to previous research and guidelines are given for clinical practice.     

Testing between the TRACE model and the fuzzy logical model of speech perception

The TRACE model of speech perception (McClelland & Elman, 1986) is contrasted with a fuzzy logical model of perception (FLMP) (Oden & Massaro, 1978). The central question is how the models account for the influence of multiple sources of information on perceptual judgment. Although the two models can make somewhat similar predictions, the assumptions underlying the models are fundamentally different. The TRACE model is built around the concept of interactive activation, whereas the FLMP is structured in terms of the integration of independent sources of information. The models are tested against test results of an experiment involving the independent manipulation of bottom-up and top-down sources of information. Using a signal detection framework, sensitivity and bias measures of performance can be computed. The TRACE model predicts that top-down influences from the word level influence sensitivity at the phoneme level, whereas the FLMP does not. The empirical results of a study involving the influence of phonological context and segmental information on the perceptual recognition of a speech segment are best described without any assumed changes in sensitivity. To date, not only is a mechanism of interactive activation not necessary to describe speech perception, it is shown to be wrong when instantiated in the TRACE model.     

Can we imagine how objects look from other viewpoints?

Many psychologists who study cognition believe that perception achieves object-centered representations that make it possible to extract representations of how the object would appear from differing viewpoints. Others believe we can achieve representations of how an object would appear by a process of visualization or mental rotation. We report experiments in which the subject tries to imagine how three-dimensional novel wire objects would appear from positions other than the one they are in. Subjects are unable to perform this task unless they make use of strategies that circumvent the process of visualization. It is suggested that the linear increase in time required to succeed in mental rotation tasks as a function of the angular discrepancy between the figures compared is the result of increasing difficulty rather than of the time required for rotation.     

Patterns of movement in the first 6 months of life: new directions

The field of infant perceptual development has relied heavily on the preferential-looking and habituation paradigms. Despite the obvious advantages of employing standardized methodologies, there is a need to study how perceptual variables give rise to and guide action beginning in the neonatal period. It is argued here that, in the first 5 months of life, it is important to distinguish reflexive patterns of movement from voluntary and cortically controlled patterns. Some criteria are defined. This paper describes three experiments which utilized movement counters to record developmental changes in the frequency and synchrony of limb movements in infants under 5 months. The results show that there is a general increase in frequency of limb movements from 1 to 5 months, but with a plateau or even a decrease in activity from the middle of the third month to the end of the fourth month. It was also demonstrated that synchrony scores (co-activation) for pairs of limbs showed significant increases from 1 month to 5 months. Finally, in all three experiments the presentation of an attractive toy resulted in suppression of activity. The results of the three experiments are interpreted to measure a gradual increase in cortically controlled movement patterns.     

Defining a family heritage and a new relationship identity: two central tasks in the making of a marriage

The roles of origin family environmental characteristics and couple consensus-building process within the development of marital relationships were examined prospectively in 16 premarital couples. Three important findings emerged. First, significant correlations were found between dimensions of origin family environment and the reported level of satisfaction within the couple's current relationship. Second, measures of the couple's ability to reach consensus concerning important interpersonal relationships appeared to be important mediators of the association between origin family environment and current relationship satisfaction. Third, important gender differences emerged that replicate and extend prior findings that portray women in the role of "relationship specialist" within their marriages. As a group, these findings were best explained by a developmental model of early marriage that envisions the young couple as facing two entwined tasks: to define both their family heritage and their new relationship identity. Overall, the importance of examining family-of-origin characteristics and consensus-building process as critical determinants of the fate of intimate relationships received strong support. The gender differences found in the literature reviewed, as well as the results of this study, have largely been overlooked by the theory and practice of family therapy. Efforts on both the research and theory construction fronts are needed to increase our understanding of the mechanisms whereby prior family experience is brought forward into current intimate relationships.     

Occupational choices of daughters of practicing rabbis

This paper examines the psychological impact that rabbis, as character types, have on their daughters. It describes how the father's impact psychologically predisposes these women to enter the helping professions in disporportionate numbers, and it shows how these job choices are often a means of coping with psychological issues connected to their upbringing.She is a candidate to become a psychoanalyst at the Chicago Center for Psychoanalytic Psychology.     

The final portrait of Christ

Artistic presentations of Jesus are as numerous and varied as the artists who created them. Whether on canvas or in music, Jesus has been portrayed as a redeemer, revolutionary, teacher, and clown. While some people are inspired by a particular presentation of Jesus, others are angered and incensed at what they perceive to be blasphemous. An example of the latter is Martin Scorsese's film, The Last Temptation of Christ. This article examines why people responded so negatively to this and other artistic presentations of Jesus. It suggests they have failed to recognize how the portrayal reflects a personal experience of the artist and is not meant to be a final portrait of Christ. And on a more unconscious level, these works of art evoke feelings within people which they fear to acknowledge and which they escape by condemning the work.     

Religious celibacy from the celibate's point of view

What do celibates consider the adaptive and maladaptive aspects of their celibate religious lifestyle? What role has celibacy played in understanding the differences between those who persevere and those who choose to resign from celibate religious life and/or ordained ministry? Using data from extensive interviews, this exploratory study begins to focus some of the perceived effects of celibacy upon personal development for both those who persevere in celibate religious life and those who resign.     

Interhemispheric transfer in schizophrenics, depressives, and normals with schizoid tendencies

Although several studies suggest that schizophrenics suffer from an impairment in the interhemispheric transfer (IHT) of information, methodological weaknesses in these studies preclude clear interpretation of their results. This study addresses these criticisms in order to provide a clearer test of the IHT theory. Schizophrenics, depressives, normal controls, and normals with schizoid tendencies were assessed on five measures of IHT (verbal and nonverbal dichotic listening, intermanual transfer, bimanual block design, finger sequence repetition) and two measures of unilateral hemispheric processing (lateral eye movements, auditory thresholds). Results consistently failed to support an IHT deficit interpretation of schizophrenia. Schizoid normals had a significantly greater right-ear advantage on verbal dichotic listening than both psychiatric groups, a result suggesting enhanced left-hemisphere activation in schizoid normals. It is concluded that the IHT theory requires stronger empirical substantiation than has been obtained to date to warrant further consideration as a central theory of schizophrenia.     

COGNITIVE EFFECTS OF LOGO AMONG BLACK AND WHITE ZIMBABWEAN GIRLS AND BOYS

The cognitive effects of LOGO were examined among 11–12-year-old black and white Zimbabwean girls and boys. Fifty-two experimental group children were exposed to a BBC LOGO programme with a screen turtle. Forty-one control group children received no exposure to computers at school. Pre-tests on four WISC-R subscales were held in January, 1987 and post-tests on the same four WISC-R subscales were held in November/December, 1987. The data were analyzed with multivariate analysis of covariance, using pre-test scores as the covariate. The results suggested that children in the experimental group did better on the WISC-R Arithmetic scale and that black girls exposed to LOGO showed particular gains in spatial reasoning, as measured by the WISC-R Block Design scale. It is concluded that LOGO appears to facilitate cognitive growth. Methodological limitations of the present study are discussed and suggestions for future research are presented.
