The effects of unstable clients in adolescent treatment: contagion versus continuity

This study examined the effects of integrating an unstable group of seriously disturbed adolescents into an existing day treatment program. Behavioral data were collected for an established group of subjects who were in treatment one year prior to and one year after the arrival of a new group of severely disturbed adolescents. It was found that the disruptive behavior displayed by the new admission subjects was not imitated by the subjects of the established group. Rather, there was a significant decrease in aggression and in the overall number of psychiatric events for the established group. The treatment milieu was seen to be resistant to the effects of the new admissions largely due to the structured form of treatment.     

Intraseptal administration of muscimol produces dose-dependent memory impairments in the rat

The present study examined the effects of intraseptal administration of the GABAergic agonist muscimol on performance of a radial-arm maze (RAM) task. Male Long-Evans rats were trained to perform a RAM task in which a 1-h delay was imposed between the sample and the test session. In this task rats have access to four out of eight maze arms during a predelay session. Following a 1-h delay, rats are returned to the maze and allowed to freely choose among all eight arms. Arms not blocked during the predelay session are baited, and entry into an arm chosen during the predelay session or a repeated entry into a postdelay chosen arm constitutes an error. Following acquisition, animals were implanted with a single cannula aimed at the medial septum. A within-subjects design was utilized to examine the effects of intraseptal administration of muscimol (0.0, 0.75, 1.5 or 3.0 nmol) on performance in this task. All drugs or artificial cerebrospinal fluid were administered immediately following the predelay session. Muscimol, a GABA-A agonist, produced a dose-dependent impairment in maze performance as evidenced by fewer correct choices in the first four postdelay choices and an increase in the number of errors. Intraseptal administration of muscimol did not significantly alter latency per choice on the RAM task nor did it affect locomotor activity levels. Muscimol-induced impairments were also observed when a 4-h delay was imposed between the fourth and the fifth maze selection, suggesting that the behavioral deficit represents an inability to store or retain spatial working memories rather than a general performance deficit. These data indicated that pharmacological manipulation of GABA-A receptors within the medial septum modifies working memory processes. The potential interaction of GABAergic and cholinergic mechanisms in the modulation of working memory processes is discussed.     

Developmental Career Assessment and Counseling: The C-DAC Model

The C-DAC model seeks to implement current development theory and to use innovative assessment measures together with improved counseling methods to improve vocational and life career counseling. At this stage, the project pays more attention to assessment, partly because if one is to counsel with career maturity in mind, one must understand the developmental status of the counselee. In career counseling, facts as well as feelings are important. Therefore, in this article the authors deal with the assessment of career development in detail, treating interests (measured by the Strong) and expressed preferences as basic status data to be viewed in the light of career maturity, the salience of life roles, and the values sought in life as moderator variables. The instruments are described and their use shown in a sample profile for assessment and checking by the reader in another readily available published source.     

Magnetic stimulation studies of visual cognition

The panoply of non-invasive techniques for brain imaging is responsible for much of the current excitement in cognitive neuroscience; sensory, perceptual and cognitive behaviour can now be correlated with cerebral blood flow as assessed by functional imaging, the electrical fields generated by populations of neurons or changes in magnetic fields created by electrical activity. Correlations between localized brain activity and behaviour, however, do not of themselves establish that any brain area is necessary for a particular task; necessity is the domain of the lesion technique. Transcranial magnetic stimulation (TMS) is a technique that can be used non-invasively to produce reversible functional disruption and has already been used to investigate visual detection, discrimination, attention and plasticity. The power of TMS as a `lesion' technique lies in the opportunity to combine reversible disruption with high degrees of spatial and temporal resolution. In this review we trace some of the major developments in the use of TMS as a technique for the investigation of visual cognition.     

Holland's theory and non-college-degreed working black and white women

The main concern of this study was to investigate differences between black and white American women employed in traditional female occupations who took the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). The VPI and the SDS were administered to 110 black and white non-college-degreed workers in three occupations (laboratory technicians, sales clerks, and clerk-typists) corresponding to three of Holland's environmental categories (Investigative, Enterprising, and Conventional). In general, the findings for the three VPI and SDS scales and for these six occupational groups are mixed. On the SDS scales, findings indicate that black and white women in the same occupation seem to be far more similar than different. On the scales of the VPI, however, white and black women in the same occupation seem to be more different than similar.     

Consistent occupational preferences and personality

This study explored the differences on personality variables between upperclass students who made congruent and incongruent occupational choices. The personality variables were operationally defined by the California Psychological Inventory and the Omnibus Personality Inventory. Congruent and incongruent current occupational choice groups were defined operationally using the Self Directed Search. The analysis of variance revealed the main effect of groups to be significant for nine personality variables. The test for the main effect of sex was found to be significant for seven personality variables. The test for interaction was found to be significant for three personality variables. Findings suggest that students in the congruent male group tend to report better maintenance of personal and vocational stability and greater satisfaction than students in the incongruent male and female groups.

Clothing: Communication, Compliance, and Choice

This study looks at some effects of five different styles of women's clothing: Formal Skirt, Formal Pants, Casual Skirt, Casual Pants, and Jeans. There were no significant differences in compliance to a request to fill out a questionnaire made by experimenters dressed in the five clothing styles, although experimenter age and sex effects were found. Ratings of photographs of the five dress styles indicate that a model was viewed by both male and female subjects as most happy, successful, feminine, interesting, attractive, intelligent, and wanted as a friend when wearing a Formal Skirt outfit and as least so when wearing Jeans. She was also seen as more active when wearing pants as compared with a skirt. Subjects' reasons for choosing what clothing to wear did not indicate that how one will appear to others is the major factor in clothing selection. It appears that clothing does communicate something about the wearer but may influence behavior toward her primarily in the absence of other information about her status.
