This paper examined differences in the degree to which fifteen specific sources of job satisfaction were related to and predictive of the overall satisfaction of department chairmen in the six model environments proposed by Holland (1973). The fifteen specific sources of job satisfaction were regressed on overall satisfaction, separately for chairmen in each environment, through the use of incremental stepwise multiple regression procedures. The results indicated that the overall satisfaction of chairmen in these six environments was differentially related to unique weightings and combinations of the fifteen predictor variables. It was concluded that environments, composed of essentially similar groups of people in different organizations, serve as job satisfaction reinforcer systems in a manner similar to organizations as illustrated by Dawis.  相似文献

A concurrent verbal task was superimposed upon the performance of a practiced bimanual motor skill by right-handed Ss. Addition of the verbal task did not increase the total number of errors; however, a significant interaction between hands and conditions was observed. The right hand made significantly more errors under the verbal condition, while the left hand made non-significantly fewer errors under that condition. These findings were interpreted as supporting an attentional model rather than a model which proposes that addition of the verbal task causes control of the right hand to shift to the non-verbal right hemisphere.  相似文献

Discriminative stimulus control over masculine and feminine sex-typed play behaviors was investigated in five boys, aged 5–8 yr, with “childhood crossgender identification.” Reliable observational measures of play were obtained with two sets of toys: (a) “dress-up toys” (girls' apparel vs boys' apparel), and (b) “affect toys” (maternal-nurturance play vs masculine-aggression play). With an ABA reversal intrasubject design, certain stimulus conditions (e.g., presence of father, mother, male, or female stranger) were found to be discriminative for reliable changes in sex-typed play. Sex-typed play was found to vary as a function of the social stimulus situation and as a function of the type of play response required. All children played predominantly feminine while alone in the playroom. While no single environmental stimulus was consistently discriminative for masculine play across children, at least one stimulus condition was found for each subject under which he played predominantly masculine.  相似文献

This report describes an instrument that was designed to measure an individual's level of cognitive vocational maturity in six areas: Fields of Work, Job Selection, Work Conditions, Education Required, Attributes Requited, and Duties. Procedures used in developing the item analysis research form and the final form of the instrument are described. Sample items from each subtest are presented. Kuder-Richardson reliability estimates for each of the six area subtests are presented for grades 6–9. Both criterion-related and construct validity data are presented. Pupils whose vocational choices were in agreement with their field of interest and their ability level scored higher on all subtests than pupils whose choices agreed neither with their interests nor with their ability level. Mean scores on all area subtests increase across grades levels, thus providing support for the claim that vocational maturity behaviors are developmental ones.  相似文献

A comparison is made between the Vocational Development Inventory and the Readiness for Career Planning scale when both were administered to the same sample. An analysis of covariance, with intelligence controlled for, indicated that both instruments show an over-all progression in vocational maturity at different grade levels, as well as differences between socioeconomic groups. A correlational matrix found vocational maturity scores from the two instruments to be significantly related.  相似文献

The prediction that the ordinal property of natural number symbols (using these symbols to represent the terms in an ordered progression) is more easily learned than the cardinal property of natural number symbols (using these symbols to represent the manyness of collections) was examined in this experiment. Preschoolers who evidenced no proficiency with either the ordinal or cardinal properties of natural number symbols were trained to acquire these properties via simple feedback. Both properties proved to be trainable. The most important findings were that the ordinal property was much easier to train than the cardinal property, ordinal training effects were more durable across a 1-week interval than cardinal training effects, and ordinal training appeared to transfer better than cardinal training.  相似文献

Two experiments investigated the effects of shifting from either nonreinforcement or partial reinforcement (PRF) to continuous reinforcement conditions (CRF). In the first experiment, three groups of rats were given food reinforcement under CRF conditions in a runway followed by regular extinction trials (RE), extinction trials where Ss were delayed for 30 sec before entering the empty goal box (DE), or CRF trials where Ss were delayed for 30 sec before entering the baited goal box (DF). Then all Ss were run on the delayed reinforcement condition (DF). In the final delayed reinforcement condition, group DE ran significantly faster than group DF, reflecting positive contrast. In the second experiment, four groups of rats were trained in a runway to receive either 4% or 18% sucrose reinforcers under either PRF or CRF conditions. Then all Ss were transferred to a Skinner box and bar presses were continuously reinforced, with each S continuing to receive the same sucrose concentration as before. The former PRF Ss, regardless of the reinforcer, bar pressed at a significantly higher rate in the Skinner box than the former CRF Ss. The evidence seemed to favor the view that the effectiveness of a reinforcer is not an absolute, unchanging quantity but rather depends on the historical context in which the reinforcer occurs.  相似文献

A total of 540 first, fourth, and eighth graders, equally divided by sex, were run on a two-choice discrimination task under one of three reinforcement conditions: reward (R) for correct responses, punishment (P) for incorrect responses, or reward and punishment (RP) for correct and incorrect responses. Half the Ss were tested by a male E; half, by a female E. Across all developmental levels, learning was superior in the P group. Complex interactions involving sex of S and E underline the importance of organismic variables in discrimination learning and in specifying parameters of reinforcer effectiveness.  相似文献
