Temporal factors in visual perception as related to aging

Older Ss, in the age range 30–55 years, were compared on certain temporal characteristics of visual perception. Experiment I confirmed a previous finding that older adults required an appreciably longer exposure duration to identify forms, even when equated with younger adults on standard measures of visual acuity. Experiment 2 found that older adults have a longer critical duration over which time-intensity reciprocity holds for form identification. The results were discussed in terms of such concepts of psychological time as the psychological moment.     

Recognition deficits resulting from focussed attention in aphasia

Summary Two nonverbal short-term memory tasks, a Picture Recognition and a Paired Association Task, were performed by matched groups of aphasics and brain-damaged controls (N=52 each). For both tasks the alternatives on the answer forms differed systematically on three dimensions, one of which had been highlighted experimentally for each item before the target picture was indicated. In both tasks aphasics made more errors than braindamaged controls only with respect to those features that had been stressed beforehand; they were less able than controls to take advantage of focussed attention. The number of these errors was correlated with performance in the Token Test, a picture naming and a word comprehension task.There were no differences between the groups in response to variations in the semantic saliency of the discriminating features or in the semantic and phonetic relationship between words denoting the reference stimuli. The lack of interactions might have been due to a strong ceiling effect in both tasks.     

The contexts of adolescents' chronic life stressors

Proposed and tested a model of the determinants of adolescents' chronic life stressors, consisting of sociodemographic, personal, and contextual stress and coping factors, using baseline and 1-year follow-up data from 259 adolescents who varied in their psychological and physical health. Concurrent regression analyses at Time 1 and at Time 2, and longitudinal regressions that controlled for the levels of chronic stressors 1 year earlier, showed that sociodemographic, personal, and contextual factors each made a significant contribution to predicting adolescents' ongoing stressors with their mother, father, siblings friends and classmates and teachers at school. Personal factors of an emotional temperament and low perceived self-worth, and contextual factors of more negative life events and fewer social resources, were related to more chronic stressors. Suggestions for further development of the model are discussed. This research was supported by the William T.

Sex and marital status in relation to the treatment and outcome of alcoholic patients

This article focuses on gender and marital status differences in the treatment process, posttreatment experiences, and outcome of 332 alcoholic patients and explores the utility of several sex-role models in explaining the observed findings. Among men patients, being married is related to better treatment outcome, but the marital status difference is negligible among women patients. Participation in group therapy is related to better outcome for men relative to women; exposure to educational materials on alcoholism is associated with better outcome of women relative to men. Men and women patients also differ in the way in which their perceptions of the treatment environment are related to outcome. After discharge, unmarried women and married men are most likely to receive aftercare outpatient treatment, which is also related to better outcome among men patients. The findings underscore the importance of gender and marital status factors and of patient-program congruence effects in the treatment outcome of alcoholic patients.This research was supported in part by NIAAA Grant AAO2863 and by Vetrans Administration Medical Research Funds. The authors wish to thank Ruth Lederman for her valuable assistance with data analyses, and John Finney and Deborah Shields for helpful comments on earlier drafts.     

Analytical competence and language impairment in aphasia

Matched groups of Broca's and Wernicke's aphasics, brain-damaged patients without aphasia and chronic schizophrenics were tested in a nonverbal matching task where the subject had to indicate which of two pictures was more closely linked to a clue picture. Eight additional verbal and nonverbal reference tasks were administered. Both aphasic groups performed worse than brain-damaged controls when the identification of individual attributes or actions shared by clue and referent was required, but were unimpaired when the two had a set of referential-situational associations in common. Factor analyses resulted for both groups in two factors, one of which represents general Language Impairment. For the Broca's aphasics this factor was closely related to general organic deficit as measured by the Trail Making Test; for the Wernicke's aphasics it was associated with tasks which might be considered illustrative of analytical competence in isolating and comparing individual features of objects or concepts.     

Student physical symptoms and the social climate of college living groups

Student physical symptoms were related to the social climates of university living groups. A Physical Symptom Risk Scale, a new subscale of the University Residence Environment Scale, which relates consistently to physical symptom complaints for male, female, and coed living groups, was developed. Living groups characterized by high student physical symptoms were perceived by students as low in involvement and support, high in competition, and low in student influence. The results indicate that certain types of social environments may be "high risk" settings in that they support and possibly facilitate complaints of physical symptoms. These settings may be amenable to early "environmental diagnosis," preventive counseling, and change-oriented social systems intervention.     

INTEGRATING EVOLUTION: A CONTRIBUTION TO THE CHRISTIAN DOCTRINE OF CREATION

Abstract. Science has demonstrated that the universe creates itself through its own history. This history is the result of a probabilistic process, not a deterministic execution of a plan. Science has also documented that human beings are a result of this universal, probabilistic process of general evolution. At first sight, these results seem to contradict Christian teaching. According to the Bible, history is essentially the history of salvation. Human beings therefore are not an "accident of nature" but special creations to be saved. With deeper theological probing, it becomes clearer, however, that creation must create itself. The Christian God is the loving God who enters into a loving relationship with human beings if they desire to reciprocate. If creation could not create itself, human beings could not be free. Without freedom to ignore or reject God's love, the central act of the Christian God, the drama of salvation, would become a parody played by marionettes in the hands of a supernatural manipulator. Christians should welcome the fundamental insight brought forth by science that the universe, including human beings, created itself through its own history. This article will try to show that this scientific insistence is required and confirmed by the intrinsic character of the orthodox, Judeo-Christian concept of God. That nature has to create itself, including human beings, secures human freedom and with it, the responsibility for human actions. From this perspective one might better understand the Bible in the light of God's revelation through the book of nature.     

Unerwünschte und schädliche Wirkungen von Psychotherapie

Unwanted effects or even damage due to psychotherapy are largely neglected issues within psychotherapy research as compared to other fields. On the other hand, it is reasonable to assume that unwanted effects of a treatment which intends to influence patients into a positive direction are very likely. The rate of negative effects of psychotherapy (the deterioration effect according to Bergin) is consistently estimated to be 10% of all cases and shows this same rate in a variety of studies. This review highlights side effects of psychotherapy both on the part of the patients and of the therapists. It reports unwanted effects related to different psychotherapeutic methods, i.e. psychoanalysis, cognitive behaviour therapy, client-centered psychotherapy and – beyond these basic orientations – group psychotherapy. The paper also reports on negative effects of psychotherapy on an untreated partner. Finally, some proposals are given on how negative effects of psychotherapy could be diminished. The authors especially highlight the possibilities of changing the therapist, the treatment technique, or the theoretical treatment approach as a way to reduce negative effects.
