Locus of control,choice, and satisfaction with an assigned task

P. E. Spector's (1982, Psychological Bulletin, 91, 482–497) hypothesis that under conditions of freedom of choice persons characterized by an internal locus of control will experience greater satisfaction with an undesirable task than persons characterized by an external locus of control is considered in light of distinctions between perceived control and perceived choice. Perceived choice is proposed as an intervening variable implicit in Spector's argument. This reasoning was tested with 46 male and female college student participants in a 2 (Choice) × 2 (Locus of Control) factorial design experiment. An interaction of Choice × Locus of Control on task satisfaction was obtained such that internals tended to be more satisfied when given a choice while externals experienced greater satisfaction when not given a choice. The implications of this result for Spector' hypothesis and for the manner in which undesirable work is assigned are discussed.     

A demonstration of the costs and benefits of expertise in recognition memory

In their area of expertise experts know more potentially interfering facts than nonexperts do, yet their memory IS superior to that of nonexperts. This has been termed the “paradox of interference.” We proposed that the ability of experts to go beyond the information given allows them to infer the presence of items that might not otherwise be remembered. However, such inferences can also be detrimental to accurate recognition memory in that such inferences might become confused with actual targets. We examined the benefits and costs of expertise in two recognition memory experiments In which experts and nonexperts participated. Experts in Ex-penment 1 were knowledgeable about baseball; those in Experiment 2 were knowledgeable about Ohio geography. Distractors in both studies bore a synonymous, an inferential, or no special relation to the targets. In the last instance, experts had recognition memory superior to that of the nonexperts. When the distractors were related to the targets, however, the non-experts were superior. We proposed that experts' inferential behavior is a contributor to their generally superior memory, but that task demands can convert this asset into a liability.     

The psychological refractory period as a function of performance of a first response

Proponents of a “single channel” theory of the psychological refractory period have not specified whether the single channel occupies only the decision component of the response selection, only the motor or response component, or both. In this experiment, the delay in the RT to the second of two successively presented stimuli was examined as a function of whether or not an overt motor response was made to the first stimulus, keeping the decision component constant. It was found that in both conditions RT₂ was delayed, suggesting that the decision component was a part of the single channel. However, RT₂ was delayed by a significantly greater amount if a motor response was required, indicating that the motor component is part of the single channel as well. Implications of the results for an expectancy theory of the psychological refractory period are discussed.     

The effect of abnormal displacement of the retinal image during eye movements

The displacement of the images on the retina that results from a turning of the eye does not lead to an apparent motion of what is seen, It has been generally assumed that this is due to a compensating process which takes eye movement into account and serves to discount those image displacements that result from eye movements, It follows from this view that an abnormal image displacement, that is, an image displacement that is larger or smaller than the causing eye movement would warrant, should lead to an experienced displacement of the target. Abnormal image displacement was produced by placing the eye in the converging or diverging bundle of rays from a point source that form behind a strong positive lens; this arrangement yielded a disc-shaped image, the projection of the pupil onto the retina, which displaced abnormally during eye movements. By changing the position of the eye along the axis of the lens in relation to the crossing point of the bundle, the degree to which the displacement was abnormal could be varied, For various displacement rates ranging from 25% to 120 and 400% of normal, abnormal displacements produced by incidental eye movements remained unnoticed, Only where eye movements were intentional did some of our Ss report shifts of the perceived image. It is suggested that the organism copes with the image displacement resulting from the ever-present incidental eye movements not by compensation but by ignoring them.     

Neuropsychiatric and experiential correlates of violent juvenile delinquency

This article reviews evidence regarding contributions of neuropsychiatric and psychological vulnerabilities to violent delinquency, and the interaction between intrinsic vulnerabilities and experiential factors in the genesis of antisocial juvenile behavior. Consideration is given to biochemical and physiological factors, genetics, medical status, and neurological, psychiatric, and neuropsychological factors. Implications for treatment are discussed.     

Transitional phenomena as evidenced in prayer

In this paper, we demonstrate that the study of prayer facilitates understanding of the deeply personal object related nature of religious experience. Within prayer, individuals enter the transitional sphere and meet their God representation. Both conscious and unconscious aspects of prayer can be made available through the use of a projective test developed by the authors, known as STARR: Spiritual Themes and Religious Responses test. The data obtained suggest the usefulness of Winnicottian concepts of transitional phenomena, playing, communicating, and capacity to be alone as a contemporary psychoanalytic framework for interpreting religious experience.
