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.     

Consistency of the labial temperature change measure of human female eroticism

Six adult, human female volunteers participated in a study to determine the consistency of their pattern of sexual arousal to two erotic films over two experimental sessions. Sexual arousal was assessed objectively by means of continuous measurement of temperature changes of the labia minora and subjectively by periodic self-ratings. Each subject developed increases in labial temperature to both film presentations that ranged from about 0.10°C to 1.36°C above basal levels. The amount of temperature change in a subject's labia minora during the first film presentation was significantly correlated with that during the second film, and there was a reasonable degree of consistency across the two sessions with regard to the rate at which the subject's labial temperature subsided towards basal levels after the cessation of erotic stimulation. Labial temperature changes and subjective ratings were also significantly correlated during each of the two film presentations.     

An empirical test of the covariation analysis in causal attribution

The present investigation was designed to reveal the cognitive inference processes associated with both detection and utilization of covariation information in causal attribution. Male undergraduates were (a) informed that a test was easy or difficult and shown a videotape in which (b) the test-taker's performance was high or low, and (c) covariation between the test-taker's effort expenditure and trial-by-trial outcome was present or absent. High performance was attributed to the test-taker's effort and ability, whereas low performance was attributed to the difficulty of the test. However, recognition of the covariance relationship decreased the attribution of high performance to ability and of low performance to test difficulty and increased the attribution of low performance to effort. Effort attribution in the high performance condition was independent of covariation information. The results are discussed in terms of the relationship between covariation information and typical beliefs about the causes of achievement outcomes.     

A case study approach to delivering and evaluating services by a school psychologist

Two interrelated problems in delivering school psychological services by one school psychologist acted as a motivating force behind this study: the problem of how to plan and render services to a school system where the ratio of students to school psychologists is high, and the problem of how to determine the degree of effectiveness of these services. This study describes an approach which consisted of three distinct services rendered by a school psychologist. Evaluative measurements of the services were made in two areas: the effect of the services on the ongoing operations of the system, and the evaluation of the services by school personnel exposed to the services directly or indirectly. The relative merits and the limitations of such an approach are discussed.     

Extraversion and the orienting reaction habituation rate to visual stimuli

Eysenck's (1967) proposal that introversion is characterized by increased levels of activity in the cortico-reticular loop was treated in a series of experiments which compared high, middle, and low extraversion groups on the basis of OR habituation rate to visual stimulation. Generally, introverts were observed to have longer OR habituation rates to chromatic and word stimulation than extraverts as evidenced by cardiac, electrodermal, and vasomotor indices of habituation rate, a result which endorses Eysenck's hypothesis. Results are also discussed from the standpoint of individual differences in autonomic response.     

The usefulness of distinguishing between a defensive and a nondefensive external locus of control

The study's purpose was to determine whether a distinction can be made between individuals adopting an external locus of control as a defense and those adopting the orientation because it reflects their life experience. It was hypothesized that the two groups differ in the amount of personal responsibility they accept for task outcomes. Internals and externals were identified and then further designated as high or low in action taking. Among externals, a high action-taking score implied defensiveness. Subjects randomly received either success or failure feedback on a presumed task of interpersonal sensitivity. Defensive externals varied their causal attributions as a function of outcome, whereas nondefensive externals did not (p < .05). The distinction between defensive and nondefensive external control was thus supported.     

Recognition memory of retrieved sequences of words

The subject was asked to retrieve words belonging to a given category, natural or artificially created. After n words were retrieved, a recognition task was given either immediately after or after a delay (4 hours, 7, 14, or 28 days). Several probe words were presented and the subject had to decide whether each had been retrieved or not. The length of retrieval sequence, n, was systematically varied. Results of three experiments showed that, in general, mean decision time was almost independent of n. Namely, recognition regarding self-generated lists of words seems to be due to a different information processing than recognition regarding lists of words presented by the experimenter to memorize. Implications of the findings for retrieval from long term memory were discussed.
