Logical searches of young children in hiding and finding tasks

Thirty-two 3 and 32 4-year-olds were tested on two tasks which required them to infer the location of a concealed object. In the hiding tusk the child watched while an object was hidden and then attempted to find it; in the finding tusk the child watched while one object was found and then attempted to find a duplicate of it in the same place. Each sequence of events that the child watched ruled out two of the four locations in a linear array as possible hiding places for the object, but did not specify which of the remaining two contained it. The children did use the information conveyed by the sequences of events to decide where to search. Older children generally did better than younger children both in their first choices and in their second choices when the first, although correct, did not locate the object. However, neither age group made the correct choice of a second location consistently. This suggested that the children encountered mnemonic or logical difficulties, or both, because of the fact that two locations were equally compatible with a given sequence of events.     

Learned helplessness and the detection of contingency: A direct test

Two studies tested a basic hypothesis of the learned helplessness model: That performance deficits associated with exposure to uncontrollable outcomes are directly mediated by an individual's perception of response-outcome independence. In the first experiment 48 subjects were exposed to noise bursts. For one experimental group, the termination of the noise was response-contingent. For five other groups, noise-burst termination was independent of subjects' responses. These five groups varied in the number of trials on which they received positive feedback: As predicted, subjects overestimated the amount of control they had over noise termination as a positive linear function of the amount of noncontingent positive feedback they received. Although subjects exposed to either noncontingent positive or negative feedback showed subsequent performance deficits on an anagrams task, the expected relation between perceived control and subsequent performance failed to emerge. These findings were replicated in a second experiment. In addition, subjects' locus, stability, and globality attributions failed to predict subsequent performance. These results call into question the central premises of helplessness theory: That perceived uncontrollability and causal attributions mediate learned helplessness.     

Outcome in short-term group psychotherapy

This study examines the effectiveness of planned dynamic short-term group psychotherapy in a health maintenance organization setting. The groups, conducted by experienced short-term psychodynamically trained therapists, focused on common life-stage issues. A pretest/posttest design was employed; group participants completed a battery of self-report measures before, after, and 4–6 months after treatment. Group participants made statistically (and clinically) significant positive changes on the majority of change measures. They saw themselves as improved on target problems, became far less symptomatic, and reported considerable growth in interpersonal functioning.     

Development and Evaluation of a Decision Aid About Prenatal Testing for Women of Advanced Maternal Age

Objective: To develop and evaluate a decision aid designed to prepare patients of advanced maternal age for counseling about prenatal diagnostic testing. Setting: A regional genetics center. Design: A before/after study. Interventions: Participants used an audioguided workbook to learn about options and outcomes and to clarify personal risks, values, questions, and predispositions. Subjects: 21 women of advanced maternal age and 17 spouses. Main outcome measures: Knowledge of prenatal testing alternatives, decisional conflict, level of anxiety, and acceptability of the decision aid. Results: After using the decision aid, participants had significantly reduced decisional conflict (uncertainty) and a significant increase in knowledge. There was no effect on state or trait anxiety. More than three-quarters of participants were satisfied with the length, clarity, balance, and acceptability of the decision aid. Conclusions: The decision aid shows promise as a useful aid for preparing couples for counseling.     

Effects of researcher follow-up of distressed subjects: tradeoff between validity and ethical responsibility

Researchers studying depression often encounter research participants in serious preexisting distress. Examining investigators' ethical responsibilities to these subjects, Stanton and New (1988) found that depression researchers reported actions that ranged from doing nothing to contacting both the distressed subject and a significant other. By experimentally manipulating consent form information regarding potential treatment referral, we examined whether subjects (n=357) adjusted their responses on depression measures as a function of the level of follow-up they expected to receive. Results reveal that subjects who potentially could receive the most intrusive intervention (i.e., experimenter contact with the subject and a significant other) were less likely to report depressive symptoms than were subjects who anticipated less intrusive follow-up. Willingness to report depressive symptoms in particular conditions varied in part as a function of subject sex. Thus, ethical safeguards used in studies with subjects in preexisting distress may have consequences for the validity of self-report depression measures.     

Familiarity and recognition of faces in old age

Elderly persons exceed young adults in false recognitions of new faces. One account claims there are age-related deficits in memory for context of encounter with faces. Because of these deficits, elderly persons frequently recognize faces on the basis of perceived familiarity (i.e., resemblance to face representations in memory), which is high for some new faces. To test this context-recollection hypothesis, we had young adult and elderly subjects judge whether faces: (1) had been seen previously in a test (though no face was repeated), and (2) were subjectively familiar (though no face was famous). The elderly exceeded the young subjects in seen-before judgements (false recognitions), and only the elderly showed a positive correlation between false recognitions and subjective familiarity. In Experiment 2, this finding was extended from false recognitions to correct recognitions, supporting the view that elderly persons, compared to young adults, rely more on resemblance in recognizing faces.     

False recency and false fame of faces in young adulthood and old age

Studies of age differences in face recognition have shown age-related increases in false-alarm errors: elderly persons exceed young adults in judging new faces to be old. To distinguish among theoretical accounts of this finding, we compared young and elderly subjects in two recognition tasks: (1) that of judging whether faces were recent or nonrecent, and (2) that of judging whether faces were famous or nonfamous. The major independent variable was prior presentation of faces-including nonrecent and nonfamous foils-1 week before the test. False recent judgments in response to nonrecent faces and false famous judgments in response to nonfamous faces were higher among the elderly. Moreover, these age-related differences in false-alarm rates were larger for faces viewed 1 week previously than for entirely new faces. The findings suggest that, compared to young adults, older individuals rely relatively more on perceived familiarity, and relatively less on recollection of context, in making recognition decisions.     

Psychosis in German prisoners: Comparison of the clinical appearance of psychotic disorder of an imprisoned population with a not detained community group

Surveys confirm risk factors for the incarceration of patients with psychosis including homelessness and comorbidity. There is also agreement that severe psychosis can lead to violence. Data describing prisoners with psychosis in Germany are scarce. We aimed to compare patients with psychosis in a prison hospital and patients with psychosis in a community hospital. Demographic data were collected, as well as comorbidity in the form of substance dependence and a psychiatric assessment using the German version of the 18-item Brief Psychiatric Rating Scale (BPRS) and the Positive and Negative Syndrome Scale (PANSS). In the prison hospital group more patients were homeless (17 versus 2%) and non-German (36 versus 4%). There were also more patients with substance dependence or abuse in the prison hospital group. The total scores of BPRS and PANSS were lower in the prison hospital group (BPRS, 43.8 versus 51.2; PANSS, 71.5 versus 83.7). We assume that social disintegration for mentally disturbed offenders prior to incarceration hindered effective treatment. To avoid further social disintegration and possible further deterioration of mental health status of released offenders, which may lead to reoffending after imprisonment, discharge management after release from prison should be improved.     

Short Form of the Social Anxiety Scale for Adolescents among community and institutionalized Portuguese youths

Background/Objective: Social anxiety is a common issue arising in adolescence that can cause significant impairment and have detrimental consequences for development in the absence of treatment. In this study we examined the factor structure and the psychometric properties of a 12-item short form of the Portuguese-Language Social Anxiety Scale for Adolescents (SAS-A-SF). Method: A community adolescent sample (N = 835) and a young offender sample (N = 244) completed the SAS-A, the Basic Empathy Scale and the Reactive-Proactive Aggression Questionnaire. Confirmatory factor analysis, internal consistency, cross gender and cross sample invariance, convergent and discriminant validity of the SAS-A-SF were analyzed. Results: The confirmatory factor analysis revealed that the 3-factor second-order model obtained the best fit.The results provided evidence that the SAS-A-SF is a psychometrically sound instrument that shows measurement invariance across genders and across samples, good reliability and positive correlations with empathy. Conclusions: The Portuguese version of SAS-A-SF is a useful, time-efficient tool for both researchers and practitioners who need to assess social anxiety, a relevant construct in adolescent psychopathology.
