Interhemispheric phase relations in children of early school age

The cross-correlation method was used to measure interhemisphere phase differences over four areas of the brain in 22 healthy children aged between 7 and 10 years. Apart from defining normal values, the authors describe age-dependent characteristics and changes that take place as a result of mental stress.     

Levels of selection and capacity limits

Subjects performed a visual target-detection task in eight experiments. We examined the effects of word relevancy (word in relevant or irrelevant location) and display load (1-4 words) on physical, semantic, and controlled processing of nontargets. Interwoven with the detection task was a test-word identification task that was used to measure priming potency of nontargets. Physical and semantic levels of processing were measured in terms of identity and semantic priming, respectively. Nontarget primes were repeated as test words in identity priming. Nontarget primes were semantic associates of test words in semantic priming. Controlled processing of nontargets was measured in terms of recognition memory on a subsequent test. All measures increased with word relevancy and decreased with display load. The priming effects remained intact even when word presentation was speeded up and controlled processing was sharply curtailed. The data indicate that all levels of processing are selective and capacity limited.     

Perceptual learning of a non-focal color discrimination between ages three and six

A match-to-sample task and a preference-ranking procedure were used to provide predifferentiation experiences on a color discrimination of 3-, 4-, 5-, and 6-year-old children. Chronological age was the best predictor of task success. Six-year-olds averaged twice as many correct matches as 3-year-olds. Gender and predifferentiation experience were not significant as main effects or in interactions affecting test performance. There was no difference between scores of untrained and trained children. The predifferentiation experiences had no effect. The data suggest that the years between 3 and 6 may be an important period in the development of the perceptual abilities needed to discriminate among subtle differences in one hue. Boys' and girls' abilities seem to develop at the same rate during this age span.     

SOCIAL INFLUENCES ON “SELF-STIMULATORY” BEHAVIOR: ANALYSIS AND TREATMENT APPLICATION

We tested the hypothesis that the “self-stimulatory” behaviors exhibited by some individuals may be socially mediated. Four developmentally disabled children who exhibited hand flapping and body rocking participated in a series of three experiments conducted to assess the influence of social variables on stereotyped behavior and to develop a treatment based on the assessment. Experiment 1 used an assessment procedure to determine the relative influences of social attention and task demands on stereotyped behavior. For all four children, hand flapping and body rocking increased when difficult academic tasks were introduced. Experiment 2 involved the use of a procedural time-out and demonstrated that removing task demands contingent on stereotyped behavior resulted in increased rates of hand flapping and body rocking. In Experiment 3, these results were used to develop a communication treatment that consisted of teaching the children to request assistance on the difficult tasks. This treatment resulted in significant reductions in self-stimulatory behavior. These results are consistent with the hypothesis that some forms of repetitive stereotyped behavior may come to serve social functions (e.g., escape from aversive situations). Teaching a functionally equivalent communicative alternative to escape-motivated stereotyped behavior can be an effective form of intervention for this problem.     

Psychological concepts useful in the building of political foundations between nations: Track II diplomacy

There are two phases in the process of negotiating for peace with antagonistic national groups. The leader (or leaders) of one such group will not negotiate with his opposite number until political foundations to support such negotiation are laid down, and obstacles to peace identified and dealt with; at least some measure of success is anticipated by both sides. Accordingly, the first phase requires the building of bridges between those representing opposing nations. The activities in this preliminary phase are sometimes called Track II diplomacy; they differ from those of official or Track I diplomacy. I suggest two kinds of concepts that may be useful in Track II diplomacy, and present them in the hope of initiating further discussion, and exploration of metapsychological underpinnings of each concept. As Mitscherlich (1971) suggested, the psychology of international politics may be better understood if psychoanalysts are willing to engage in interdisciplinary work with others engaged in such endeavors.     

Gender influencers on work values of black adolescents

Work values and key influencers of a sample of black male and female adolescents were examined. Results indicated that boys and girls valued both the intrinsic and extrinsic rewards of work; however, girls reported slighter stronger extrinsic values than did boys. In addition, the sexes reported differences in the importance of specific work values such as "making lots of money," and "doing important things." When naming a key influencer, respondents tended to cite a same-sex and race individual. Sex of one's key influencer was related to certain work values, with subjects reporting a male key influencer valuing "trying out one's own ideas" and "having a secure future" more than those reporting a female key influencer. The interaction of sex of subject and sex of key influencer was significant on one of the work value outcomes. Implications of these findings are considered.     

The Hispanic Treatment Program: Principles of effective psychotherapy

The Hispanic Treatment Program was an inpatient psychotherapy Unit at the Colorado State Hospital that operated from October 1979 to February 1982. Staffed exclusively with personnel of Hispanic heritage, the Program emphasized the use of linguistic and cultural elements, as well as the customs and beliefs characteristic of Hispanic culture. A specialized inpatient treatment unit for Hispanic patients with psychotic (especially, schizophrenia) disturbances, the Program offered a unique opportunity to these patients by providing a variety of psychotherapies conducted in a culturally-sensitive manner. Spanish and English were used in a manner conducive to enhancing the treatment process, with flexibility in use of language.This project was supported by Grant No. ROlMH29016-01A2, awarded by the National Institute of Mental Health, Center for Minority Group Mental Health.The authors acknowledge Gregorio Kort, M.D. and Wayne Smyer, M.A. and other staff for their contributions to the development and success of the Hispanic Treatment Program.Original version of paper was selected for the First Senior Award given by the Psychological Services Center's (NYSCP) Minority Mental Health Award Competition.     

A developmental study of timing behavior in 4 1/2- and 7-year-old children

The present study investigated effects of age and instructions on temporal regulations of behavior in children. In the first experiment 4 1/2-year-old and 7-year-old subjects were trained with a DRL (differential reinforcement of low rates) 5-s and a DRL 10-s schedule. Results demonstrate that age and timing performance are related. Seven-year-olds are more efficient than the 4 1/2-year-olds. A striking decline in the 4 1/2-year-old children's capacity to space responses was observed in the DRL 10-s schedule as compared to the DRL 5-s schedule. Analysis of individual performances suggests that the evolution of DRL performance between 4 and 7 years of age depends not only on the development of the capacity to delay responding but also on the acquisition of the ability to represent the reinforcement contingencies, that is, the temporal parameters of the task to oneself. In order to test this hypothesis a second experiment was conducted where instructions to wait between operant responses were given to a group of 4 1/2-year-old subjects at the beginning of a DRL 5-s and a DRL 10-s schedule. The results show that these instructions enhance DRL performance. By directing the 4 1/2-year-old subjects' attention to the temporal requirements of the task, instructions led to efficient performance and accurate timing of responses to the DRL schedule.     

PERFORMANCE APPRAISAL AND TERMINATIONS: A REVIEW OF COURT DECISIONS SINCE BRITO V. ZIA WITH IMPLICATIONS FOR PERSONNEL PRACTICES

Court cases since the classic Brito v. Zia (1973) decision dealing with terminations based on subjective performance appraisals are reviewed. Professional interpretations of Brito v. Zia are also examined and criticized in light of professional practice and subsequent court decisions. Major themes and issues are distilled from the review of cases, and implications and recommendations for personnel practices were discussed.
