Latent inhibition and learned helplessness in children: Similarities and differences

Four experiments used a common set of procedures to investigate the occurrence and the generalization of learned helplessness (LH) and latent inhibition (LI) in 10- to 11-year-old children. In Experiment 1, preexposure to response-outcome independence impaired performance (i.e., LH) on two subsequent tests: The first was similar to the preexposure situation, the second was not. Moreover, LH occurred whether preexposure involved positive or negative feedback. On the other hand, noncontingent stimulus preexposure did not impair subsequent performance, i.e., LI was not obtained in the first experiment. Experiment 2 replicated the LH findings of Experiment 1: LH occurred following preexposure to response-independent feedback, regardless of whether that feedback was positive or negative, and LH generalized to a situation that was different from the preexposure situation. In addition, the stimulus preexposure procedures of Experiment 2 were embedded in a “masking” task and, under these conditions, LI was obtained. Nevertheless, LI did not generalize to a testing situation that was different from the preexposure situation. Experiment 3 demonstrated that noncontingent stimulus preexposure impairs performance relative to a nonpreexposed control group, that the effect is dependent upon masking, that masking alone produces no performance decrement, and that LI is, indeed, stimulus specific. In Experiment 4, preexposure to response-outcome independence impaired subsequent performance on similar and dissimilar tests whether feedback was consistently positive, consistently negative, or randomly positive and negative over trials. In addition, stimulus preexposure produced LI only under conditions of masking and even then, LI was not evident in novel test situations. The results are discussed in terms of common and different mechanisms underlying the LI and LH phenomena.     

Legacies,archives, afterlife: re-envisioning the Li-La-Lo theatre (Tel Aviv, 1944–1948)

This article suggests re-reading documents that remain from Li-La-Lo theatrical events, which include playbills, programmes, photos, archive files, and television shows. Through this historiographic way of working, that is, the re-reading of what remains from past performances but differently, this article will demonstrate what Tel Aviv offered to the artists, what the theatre as a cultural institution offered to the residents of the city and, in the broader circle, how Li-La-Lo was an intersection of performance traditions. Historical circumstances brought the Li-La-Lo artists to Tel Aviv, and the leaders and residents of the city, who cultivated normalcy, enabled them to continue to do what they knew best: perform. Thus, performance artists strengthened Tel Aviv’s status as a cultural centre, a symbol, and embodiment of cultural heterogeneity.     

Student self-selection for specializations in engineering

The general hypothesis that students self-selecting themselves for different occupational fields differ in relevant values and interests was tested for specializations within engineering. Industrial engineers were found to be different in work values and in their image of their subfield from students of other engineering specializations. The study concludes that in terms of type of student selecting engineering, the profession cannot be treated as an undifferentiated entity. It is suggested that in future research engineering students may be regarded as relatively homogenous with respect to work values only if their area of specialization is duly considered.     

Commitment to work in immigrants: Its functions and peculiarities

It was assumed that in order to cope with the crisis of immigration, immigrants would have low expectations regarding their vocational future while maintaining a high commitment to work. The meaningfulness and the centrality of work (as components of the commitment to work), work values, and work attitudes were tested in samples of 74 immigrants, of 66 old-time white-collar employees, and of 35 ongoing executives, by means of the semantic differential technique and by a projective personality test. An adaption of Eysenck's neuroticism test was also administered. Immigrants evaluated career and work-related objects in a less positive manner in comparison with the other samples, but scored higher in work centrality and job involvement, and held more positive attitudes toward authority figures in the place of work. No significant differences in neuroticism were found.     

Developmental changes in death anxiety in childhood

A sample of 49 children divided into three age groups (3–4 years, 7–8 years, and 10–11 years) responded to a pictorial derivation of Spielberger's State Anxiety Inventory for Children (STAIC). Three pictures were used as stimuli, in addition to words, for the measure of death anxiety. The intensity measure was the response to six Hebrew mood adjectives as the child chose one of seven schematic face drawings ranging from positive to negative expressions. Reliabilities were comporable to the longer versions of the Hebrew STAIC with older children. Findings indicated significant differences in anxiety scores between the age groups, with older subjects showing higher levels of anxiety. The advantage of a single measure of death anxiety appropriate for a wide age range is discussed, as well as the implication for a developmental pattern of death anxiety.     

The role of memory and integration in early time concepts

The nature of 5- to 8-year-old childrens ' time concepts was examined by analyzing two possible explanations for the greater difficulty children demonstrate in comparing durations that differ in beginning times as compared to those that differ in ending times. The explanations were (a) poor recall of beginnings as compared to endings due to their lower salience, (b) difficulty in integrating information from both points and reliance on endings only due to their greater salience. The subjects were 630 boys and girls from kindergarten to second grade. The children were presented with a series of two lights in different orders and combinations and were asked to compare order of beginnings and endings, and duration of the two lights. Results contradicted the memory explanation. In addition, repetitious questioning about order of one point (beginning or ending) appeared to have shifted children's attention from that point to the complementary point. Possible sources of children's failure to integrate beginning and end points when comparing durations were discussed.     

A response set analysis of developmental differences in children's moral judgments

The study tested the hypotheses that 1) children may not adopt a moral response set when faced with moral dilemmas and 2) their knowledge of what constitutes a moral constellation of behaviors may differ from that of adults and may lead to developmental differences. To test these hypotheses, the study examined children's responses to a multiple choice moral dilemmas questionnaire under neutral instructions, instructions to answer as a good child or as a bad child. Subjects in fourth and seventh grade were asked whether a story hero would transgress and were required to justify their answers. In addition, questions regarding affective reactions to transgressions, confessions, and due punishment were asked. Fourth grade children answering in the good child instructions condition tended to give significantly different responses than under neutral instructions, while seventh grade subjects did not tend to differentiate between these two instruction conditions. While adult theories of morality would predict a differentiation between good and bad child instructions, on some of the measures no differences were found between good and bad child instructions. The implications of these results for cognitive-developmental theory were discussed and a general framework for interpreting the data was offered.     

Reference groups and professional self-image: The case of architects

The two objectives of this study are: (1) to investigate empirically the relationships between reference groups and the individual's self-image, as part of understanding the process of self-image development; and (2) to increase our understanding of architects' professional identity dilemma of whether to identify themselves as artists or as engineers. The study demonstrated that reference groups which were not membership groups, and even not dominant references, were significantly associated with self-image. Focusing on architectural students, it showed that although reference to artists was not dominant for most of the subjects (i.e., they did not select artists as one of the two most important groups of evaluators of one's professional work), a significant difference was found between the self-image of students who referred to artists and those who did not. The image of the former was closer to that of the artist, while the latter was closer to that of the engineer.     

Field dependence/independence and mental capacity: A developmental approach

In this study we tested a central theoretical assumption of J. Pascual-Leone's (1970, Acta Psychologica, 32, 301–345) model of cognitive development, that same-age field-dependent and field-independent children have the same developmental mental capacity. The study was conducted on a very heterogeneous population, regarding both social class and age, to allow for a large variance of performance scores. The theoretical assumption was strongly supported.
