Some antecedents of work-nonwork conflict

This study examined the relationships of three aspects of work schedules—shiftwork, length of workday, and work during weekends and holidays—with the perceived interrole conflict between work and nonwork. Personal background variables and characteristics of the work role itself were hypothesized to be directly related to the level of conflict and, in addition, to moderate the work schedules-conflict relationships. Subjects were 286 hotel employees. As expected all three aspects of work schedules were related to the level of felt work-nonwork conflict. Personal background variables were not related in any way to the level of conflict. Job satisfaction and organizational role conflict were found to be directly related to the level of interrole conflict and, in addition, to moderate the work schedules-conflict relationships. Together, job-related variables and the interactions among them accounted for over 50% of the variance in work-nonwork conflict.     

A disposition-behavior congruity model of perceived freedom

Three experiments were conducted to test a disposition-behavior congruity model of perceived freedom. The model was applied to attributions of freedom to actors who possess one of several dispositions and who can choose a behavior that is congruent or incongruent with this disposition. The model posits that attributions of freedom to an actor can be predicted from the conditional probabilities that the actor would choose each behavior available to him if he possessed the disposition congruent with it. This hypothesis was supported. However, contrary to expectations, the contribution to judgment of each conditional probability was not a function of the probability that the actor actually possessed the behavior-congruent disposition.     

Piaget's theory of space perception in infancy.

Piaget's theory of space perception in infancy is presented in the format of a hypothetico-deductive system. Eleven hypotheses are defined, regarding the perception of the agent of visual change; shape and size constancy; depth; and the perception of higher-order relationships among spatial elements. The proof Piaget offers for each hypothesis is presented in the following steps: behavioral evidence, interpretation in terms of inner states; inferences and generalizations. Presuppositions underlying the arguments are explicated. Critical notes are inserted whenever appropriate. Some general conclusions are briefly discussed.     

Testing models for the structure of vocational interests

Several studies aimed at testing the validity of Holland's hexagonal and Roe's circular models of interests showed results on which the null hypothesis of random arrangement can be rejected, and the investigators concluded that the tested models were supported. None of these studies, however, tested each model in its entirety. The present study is based on the assumption that the rejection of the null hypothesis of chance is not rigorous enough. Reanalysis of 13 data sets of published studies, using a more rigorous method, reveals that although the random null hypothesis can in fact be rejected in 11 data sets, the hexagonal-circular model was supported by only 2 data sets and was rejected by 11 data sets. The hierarchical model for the structure of vocational interests (I. Gati, Journal of Vocational Behavior, 1979, 15, 90–106) was submitted to an identical test and was supported by 6 out of 10 data sets, including 4 data sets that rejected the hexagonal-circular model. The predictions of each of the models which tend to be discontinued by empirical data were identified. The implications of the findings for the structure of interests and occupational choice are discussed.     

A hierarchical model for the structure of vocational interests

In this study a hierarchical model for the structure of vocational interests is proposed. Theoretical and methodological considerations, reanalysis of the C. E. Lunneborg and P. E. Lunneborg (Journal of Vocational Behavior, 1975, 7, 313–326) data, and an alternative interpretation of existing findings suggest that this model accounts for the interrelations among the vocational interest fields better than the hexagonal-circular models, or the four-factorial structure proposed by Lunneborg and Lunneborg (1975). The implications of this hierarchical model for vocational theory and some applications in vocational guidance are discussed.     

Self-assessment and task performance

The present study tested the idea that the amount of effort expended in task performance is a function of the amount of uncertainty in one's ability level the resulting outcomes are expected to reduce. Two determinants of expected uncertainty reduction were manipulated: prior uncertainty about one's ability level and the diagnosticity of the task. Subjects first performed an initial task and then received fictitious feedback to manipulate their prior uncertainty. To induce low uncertainty, the feedback implied that the subjects are highly likely to have either low, intermediate, or a high level of ability. To induce high uncertainty, the feedback implied that the various ability levels were equally probable. Subjects then performed a task whose perceived diagnosticity regarding the ability under consideration was varied. As expected, subjects who were highly uncertain about their ability level performed better than subjects who were relatively certain they possessed either low, intermediate, or a high level of ability. Performance also improved with task diagnosticity, and the effect of task diagnosticity on performance was more pronounced when prior uncertainty was high than when it was low. Past research on the relationship between prior feedback and subsequent performance was discussed in light of the present results and a self-assessment model of achievement behavior.     

Yesterday,today and tomorrow

1260 American subjects were timed as they responded to one of the three questions (‘What day of the week is today?’ (Tod question), ‘What day of the week was yesterday?’ (Y question), and ‘What day of the week will tomorrow be?’ (Tom question)) at one of three times of the day (early morning, mid-day and the late evening). Response times as a function of the day on which the question was posed defined an inverted U-curve for all questions in all three conditions. The Tod question always triggered the fastest responses. In the morning, responses to the Y question were faster than responses to the Tom questions, whereas in the evening the converse was the case. At mid-day responses to the Y question were faster than responses to the Tom question at the beginning of the week and slower than those at its end. The patterns of introspection associated with the responses also defined reversed U-functions. The results are interpreted in the framework of a multi-channel spreading activation model.     

Congruence and consistency derived from the circular and the hierarchical models as predictors of Occupational Choice Satisfaction

Peiser and Meir (Journal of Vocational Behavior, 1978, 12, 270–278) tested the predictability of Occupational Choice Satisfaction (OCS) using Holland's constructs of congruence and consistency as applied to Roe's classification of occupations and the circular structure of vocational interests. In the present study congruence and consistency are applied to the same data, but the constructs are defined according to the hierarchical model for the structure of interests (I. Gati,Journal of Vocational Behavior, 1979, 15, 90–106). The hierarchical and the circular models are found to be of similar efficiency in predicting OCS by congruence and by consistency. Each model, however, has its unique and distinctive predictions, and thus they seem to complement each other rather than to compete.     

Information-gathering strategies in hypothesis-testing

Three experiments were conducted to investigate the informational factors affecting the kinds of questions people ask for testing a hypothesis about another's personality. In Experiment 1, subjects formulated by themselves questions to test either the hypothesis that the interviewee is polite or the hypothesis that he is impolite. The boundary of the hypothesis was set either at an extreme or at an intermediate point on the trait dimension. Experiment 2 also varied the location of the boundary, but the hypotheses concerned extroversion-introversion and subjects chose questions from a predetermined list of questions that asked either about extroverted features or introverted features and that were either low or high in diagnostic value. Both studies found that subjects preferred to ask about features that are consistent with the hypothesis only when the boundary was extreme. In contrast, diagnostic features were preferred in all conditions. Experiment 3 showed that subjects' judgment of the diagnosticity of the various kinds of questions for discriminating at different boundaries paralleled subjects' preferences among these questions. These results were interpreted as providing support for the diagnostic strategy in social information gathering.     

Processing the information contained in another's behavior

This study investigates attributions based on behavior congruent with situational demands (in-role) and those based on behavior incongruent with situational demands (out-of-role). By analyzing these processes in terms of a Bayesian inference model, it was possible to determine (a) the diagnostic values observers intially assign to behaviors, (b) the actual informational impact of these behaviors, and (c) the degree of optimality in processing information contained therein. The main results can be summarized as follows: (1) The diagnostic value and actual informational impact of out-of-role behaviors were much higher than those of inrole behaviors. (2) Information about out-of-role behaviors was less optimally processed than information about in-role behaviors. (3) Observers assigned smaller diagnostic values to behaviors which were described in great detail than to behaviors which were described in summary statements. (4) Observers' attitudes influenced their initial beliefs about the actors but not the processing of new information about the actor. (5) The Bayesian inference model predicted observers' inferences reasonably well.     

A developmental study of the role of word order in comprehending Hebrew

Monolingual Hebrew-speaking subjects, 3, 4, 5, 6, 7, and 11 years old, as well as adults, were asked to interpret utterances consisting of two nouns and a verb. Some utterances included only word order cues while others included direct object marker and subject-verb gender agreement cues. Even though Hebrew word order is relatively free, when subjects used word order as an interpretive cue they generally assigned sentence relations according to the dominant SVO order of modern Hebrew. This trend was less strong for the interpretations of NNV utterances than of NVN and VNN utterances. There was no evidence of a developmental sequence for word order strategies. In addition, there was no evidence that word order, for any age group, was necessarily a dominant cue for assigning sentence relations when other linguistic information was available.     

Lateralization effects in lexical decision tasks

Subjects were timed as they judged whether items presented to them were English words or not. Comparisons were made between responses to nouns and to verbs, on the one hand, and between concrete and abstract nouns, on the other hand. No asymmetries were found.     

Effectiveness of social reinforcement as a function of contingent and noncontingent satiation

The social satiation effect is the inverse relation between the availability of a social stimulus and its subsequent efficacy in a reinforcing role. According to a suggested cognitive-interactive theory, the satiation effect is mediated by children's attributions of contingency between their own behavior and the experimenter's actions in the satiation treatments. Perceived contingencies depend, at least to an extent, on actual contingencies, and it was therefore predicted that a satiation effect would be observed only for groups presented in the satiation treatment with noncontingent social stimuli but not for groups presented with contingent stimuli. Middle-class 5- and 7-year-old children were subjected to a 10-min waiting period in which the stimulus word “Yafeh” (“good” in English) was presented 2 or 20 times, contingently or noncontingently. They were then given a 75-trial binary discrimination test: correct responses were reinforced with “Yafeh”. The hypothesis was confirmed in the analysis of variance. However, the predicted difference between the slopes of the contingency and noncontingency conditions was found clearly only in the older sample, while the younger children were more influenced by the number of social stimuli presented in the treatment (satiation) and less influenced by the method of stimulus presentation.     

Memory functioning as related to developmental changes in bases of organization

Two series of object drawings classifiable according to either color or conceptual category were used: one to assess dimensional salience and the other to assess free recall, clustering, and cued recall. Parallel shifts in dimensional salience and the dominance of these dimensions as organizing principles in memory were investigated in nursery school and second- and fifth-grade children. Nursery school children manifested color salience, whereas the two older groups manifested conceptual salience. Above chance clustering according to the salient dimension in each age group and some increase in the size of organization units as a function of age were found. Within age groups, neither amount nor dimension or clustering were related to amount of recall. In each group, more words were accessed by salient than by nonsalient cues. Effectiveness of nonsalient cues depended on the order of presentation for young children, whereas for older chilren they were ineffective regardless of order. Implications of these findings for encoding and retrieval processes in children were discussed.     

Developmental differences in memory for temporally neutral and temporally tagged information

Forty children (ages 7 and 11 years) listened to stories and then answered questions about temporally neutral and temporally tagged information appearing in them (e.g., “Linda is smart” vs “Linda ate an apple”). Number of presentations and free recall of the stories were manipulated to study age-related changes in the effects of additional processing on memory for the two kinds of information. Older children exhibited overall better memory, but with additional processing that difference was larger for temporally neutral than for temporally tagged information. The observed interactions among age, additional processing, and kind of information demonstrated the importance of the distinction between temporally neutral and temporally tagged information for developmental studies of memory for prose.     

Do open space environments encourage children to seek immediate gratification?

This study evaluated the effects of 14 months' exposure to open space environments on preference for delayed reward. Three hundred eighty-nine pupils in open space and conventional classes in grades 4 and 5 were individually administered one of four tests for delay of gratification. These tests consisted of a choice between an immediate, smaller reward and a delayed, larger reward. Each of the four independent studies found that approximately the same percent of pupils from each educational environment selected the delayed alternative.     

The use of natural consequences and a make-up period to eliminate school phobic behavior: A case study

The school-phobic behavior of a seven-year-old male was modified through implementing a program characterized by maximum parental involvement, restructing of natural consequences, and the use of a make-up period. Full-time school attendance was achieved on the sixteenth day of the program. The advantages of using school personnel as monitors and not as disciplinarians of the school-phobic child's behavior are discussed.     

Follow-up in classroom behavior modification: Survey and discussion

A survey of several behavior modification journals showed that only 28% of the studies conducted in educational settings reported any follow-up data. Of those studies including follow-up data, 86% reported that therapeutic gains were completely or partially maintained. Follow-up was more often reported and was longer when the subject was an individual or small group than when an entire class served as the subject. More follow-up data were based on direct observation than on anecdotal verbal reports, but the follow-up period was longer when verbal reports were obtained than when direct observation was used. A greater percentage of studies published prior to 1971 than of those published since 1971 included follow-up data. Problems in the methodology and design of follow-up research are discussed.     

Subjective probabilities and moral judgments

The two experiments reported here examined the relationship between subjective probability estimates and moral judgments (credit and blame assignment, trait attributions, and behavior evaluations). Subjects read about situations that varied in outcome valence (moral or immoral); in addition, the nature of situational demands (Experiment 1) or behavior frequency (Experiment 2) was varied. In the first experiment, subjective probabilities were related to judgments of immoral behaviors (but not moral behaviors), whereas the situational demands only had an impact on judgments of moral behaviors. Experiment 2 included a wider range of behavioral situations, and the probability estimates and moral judgments were assessed independently. In contrast to the first experiment, subjective probabilities were related to trait and behavior ratings of both moral and immoral acts. Consistent with the first experiment, however, subjective probabilities predicted blame but not credit. Across both studies, the prior expectancies were more strongly related to evaluations of immoral acts than moral acts. Implications for understanding the determinants of judgments of moral and immoral acts are discussed.     

Encoding processes in recognition and recall

The present experiments demonstrate that picture-word stimuli are differentially encoded in anticipation of a recognition test than in anticipation of a free-recall test. Subjects perform better on the retention test of which they have been informed, and different information from the stimuli is used to pass each test. These findings cannot be attributed to stimulus selection nor to pure pictorial encoding in anticipation of recognition and pure verbal encoding in anticipation of recall. Recognition is enhanced by encoding which integrates the details within each item while recall is enhanced by encoding which interrelates the items of a list.
