Attentional strategies and the visual control of discrete movements

The relationship between the availability of visual information and attention demands during the production of a discrete motor act was examined. Subjects were required to move a linear slide a distance of 15 cm in both 150 and 600 msec conditions under three light manipulations, viz., light always on; light always terminated as movement began; or, subject was unsure as to whether light would stay on or terminate. A simple key press by the index finger of the opposite hand to a tone was used as a secondary task and a measure of attention demands. The light manipulation influenced attention demands on the rapid 150 msec movement such that more attention was demanded when the subject knew the light would terminate. No such attentional strategy differences were found with the slow 600 msec movement. These findings suggest that task constraints in the form of kinematic criteria, together with the perceived availability of visual information, contribute to determining attentional strategy in movement production.     

The end phase of analysis: indicators, functions, and tasks of termination

This paper considers the end phase of analysis. Beginning with a brief review of the literature on termination, specifically the indicators for initiating the termination process, we identify the structural attainments necessary for the patient to successfully complete the analysis and to maintain smooth post-analytic functioning. We stress in this regard the significance of self-analytic functions and the relative immutability of the transference neurosis. These points are illustrated with clinical examples. Our paper concludes with a discussion of the tasks and contributions of the analyst during the termination process. We make special reference to countertransference vulnerability resulting from the analyst's own termination experiences.     

Reciprocal Effects Between Locus of Control and Job Attributes

The purpose of this study was to examine the reciprocal relationships between locus of control and job attributes of a representative sample of 1383 employees in a large Australian city. It was predicted that employees with an internal locus of control would attain jobs higher on skill-utilization, influence and income than those attained by employees with an external locus of control. It was also predicted that jobs involving high skill-utlization, influence and income would induce greater internal control beliefs than those low on skill-utilization, influence and income. Locus of control was measured using Rotter's scale (Rotter, 1966). Reciprocal causation was assessed using two-stage least squares analysis. For the total sample, it was found that locus of control and job attributes were reciprocally determined. However, locus of control was not related to influence when skill-utilization and income were controlled. When the sample was split on the basis of gender and marital status, the predicted relationships between locus of control, skill-utilization and income were found for married men only. For married women, locus of control was neither a determinant of job attributes nor an outcome of job experience. These sub-group differences were interpreted in terms of differences in job tenure, work values and occupational opportunity.     

Transfer of matching-to-figure samples in the pigeon

Three pigeons were trained on a modified six-key matching-to-sample procedure. The third peck on the figure-sample key (which presented a bird, hand, face, beetle, rabbit, fish, flower, or red hue, as the sample) lighted only one comparison key. Every three additional pecks on the sample lighted another comparison key, up to a maximum of five keys. Pecks on keys of matching figures produced grain. Pecks on nonmatching keys (mismatches) turned off all lights on the comparison keys and repeated the trial. Three figures were used during acquisition. The birds learned to peck each sample until the matching comparison stimulus appeared on one of three comparison stimulus keys, and then to peck that key. Later, five novel stimuli, employed as both sample and comparison stimuli, and two additional matching keys were added. Each bird showed matching transfer to the novel samples. The data suggest that the birds may have learned the concept of figure matching rather than a series of two-component chains or discrete five-key discriminations.     

Coping behavior in depression: report on a new scale

The Coping Strategies Scales (COSTS) were developed to provide a means of measuring how depressed persons cope with depression and to identify the behavior which they find to be most or least helpful. Items were rated by eight psychologists, psychiatrists and social workers. Those items achieving 75% level of agreement on scale assignments were included. The COSTS was then administered to 100 depressed outpatients and inpatients currently in psychotherapy. A replication study of 64 patients was also completed. Nine of the 10 scales had acceptable internal reliability, ranging from 0.70 to 0.86. An initial factor analysis of the 10 scale scores showed there to be three primary factors. Internal reliability coefficients for these three factorially-derived scales ranged from 0.86 to 0.91.
