The interaction of personality and job scope in predicting turnover

The interaction of employee personality characteristics and job scope in the prediction of turnover was studied. One hundred and nine individuals employed as machine operators (low-scope job) and scientific and technical personnel (high-scope job) within a large manufacturing organization were the sample. No direct relationships were found between personality characteristics and turnover for the combined sample of employees on high- and low-scope jobs. When correlational analyses were carried out within job scope samples it was evident that personality and job scope interacted in predicting turnover. For employees on high-scope jobs, turnover was negatively related to the need for achievement and positively related to the need for affiliation. Turnover was negatively related to the need for affiliation among employees on low-scope jobs. The implications of these findings for future research on turnover were discussed.     

Relationships between Growth need Strength and selected individual differences measures employed in job design research

The present study examines the degree to which the Growth Need Strength scales (Job Choice and Would Like formats) of the Job Diagnostic Survey (Hackman & Oldham, Journal of Applied Psychology, 1975, 60, 159–170) correlate with (a) other measures of needs and values employed in research as moderators of the job scope-job satisfaction relationship and (b) a measure of social desirability. Results showed (a) only moderate correlations between the Growth Need Strength scales and the other measures of needs and values and (b) a relatively high degree of correlation between social desirability and the Would Like measure of Growth Need Strength. Implications of these findings for job design research are considered.     

Attraction to a dissimilar stranger as a function of level of effectance arousal

An experiment was carried out to demonstrate that the relationship between attitudes of a stranger and attraction to that stranger can be mediated by effectance arousal and the consequent information search to reduce the arousal. The argument posited was that individuals under high effectance arousal produced by a confusing and ambiguous film would be attracted to dissimilar others as a source of information and uncertainty reduction. Results indicated that high levels of arousal produced greater attraction to a dissimilar stranger than to a similar stranger. This finding was reversed when an explanation was provided along with the confusing film, lending support to the uncertainty reduction position.     

A developmental assessment of children's verbal strategies for social action resolution

The objectives of this study were (1) to devise a method to assess children's developing verbal strategies for action resolution as expressed in reflection on a naturalistic, real-life social experience and (2) to examine these strategies in relation to differences in age and reflective social understanding level. In the design of this study the two independent variables were grade (second and third versus fourth and fifth) and level of reflective social understanding (level 1 versus level 2 on a social understanding interview schedule). Four small activity groups (six subjects per group), homogeneous with respect to grade and reflective social understanding level, were composed from 24 girls with middle class backgrounds. Each of the four groups met for twelve consecutive school weaks, once a week, for 90 minutes in adult supervised after-school cooperative group activities (e.g., putting on a puppet show).A Social Action Resolution Strategies interview was administered to each subject individually at the end of the twelve-week program in order to assess the child's preferred verbally expressed choice of action for resolving common conflits which arose in the activity group experience. Interviews were coded according to four levels of social action resolution strategies (0–3). Results indicated that the developmental sequence of social perspective-taking levels can be considered to underlie the range of strategies used by children to settle social conflicts as well as social understanding levels. A clear relation among level of social action resolution strategies, level of reflective social understanding, and grade was found.     

The flexible boundaried group: format, techniques, and patients' perceptions

The model of a flexible boundaried group was developed to manage the problem of irregular group attendance of chronic mentally ill patients. The central element in the model enables patients to determine, within limits, the frequency with which they will attend sessions. Review of attendance records and patient interviews from one flexible group suggest that members adhere to their contractual agreement and are accepting of irregular attenders. This finding has been supported by experiences in three additional groups composed of chronically ill individuals. These groups, comprised of regular, core attenders and peripheral members, become cohesive and form a viable therapeutic treatment structure.     

Temporal constraints on visual learning: a computational model

Given a constant stream of perceptual stimuli, how can the underlying invariances associated with a given input be learned? One approach consists of using generic truths about the spatiotemporal structure of the physical world as constraints on the types of quantities learned. The learning methodology employed here embodies one such truth: that perceptually salient properties (such as stereo disparity) tend to vary smoothly over time. Unfortunately, the units of an artificial neural network tend to encode superficial image properties, such as individual grey-level pixel values, which vary rapidly over time. However, if the states of units are constrained to vary slowly, then the network is forced to learn a smoothly varying function of the training data. We implemented this temporal-smoothness constraint in a backpropagation network which learned stereo disparity from random-dot stereograms. Temporal smoothness was formalized with the use of regularization theory by modifying the standard cost function minimised during training of a network. Temporal smoothness was found to be similar to other techniques for improving generalisation, such as early stopping and weight decay. However, in contrast to these, the theoretical underpinnings of temporal smoothing are intimately related to fundamental characteristics of the physical world. Results are discussed in terms of regularization theory and the physically realistic assumptions upon which temporal smoothing is based.
