Areas of concern and sources of advice for Israeli adolescents.

This study explored the concerns of Israeli adolescents, who grow up in a socially, politically, and economically highly stressed environment. Ninth- and eleventh-grade students (N = 1,645) completed a questionnaire in which they indicated three important problems they had recently experienced. Content analysis identified six major categories of concerns (listed in descending order of occurrence): studies and career, social "I," personal "I," existential issues, army or national service, and health and drugs. Younger adolescents were found to be more concerned with problems involving studies and career and with issues pertaining to the social "I"; older adolescents were more concerned with existential issues and army or national service. Boys were more concerned with existential issues, army or national service, studies and career, and the social "I." Girls were more concerned with issues pertaining to the personal "I." Three major sources of advice were identified: friends, parents, and brothers/sisters.     

Dividing attention within and between hemispheres: testing a multiple resources approach to limited-capacity information processing

Two experiments tested the limiting case of a multiple resources approach to resource allocation in information processing. In this framework, the left and right hemispheres are assumed to have separate, limited-capacity pools of undifferentiated resources that are not mutually accessible, so that tasks can overlap in their demand for these resources either completely, partially, or not at all. We tested all three degrees of overlap in demand for left hemisphere supplies, using dual-task methodology in which subjects were induced to pay different amounts of attention to each task. Experiment 1 compared complete and partial overlap by combining a verbal memory load with a task in which subjects named nonsense syllables briefly presented to either the left or right visual field (LVF and RVF, respectively). Experiment 2 compared complete versus no overlap by using the same verbal memory load combined with a laterally presented same-different judgment task that did not require a spoken response. Decrements from single-task performance were always more severe when the visual field task stimulus was presented to the RVF. Further, subjects in Experiment 1 were able to trade performance between tasks on both LVF and RVF trials because there was always at least some overlap in left hemisphere demand. In Experiment 2, performance trade-offs were observed on RVF (complete overlap) trials, but not on LVF trials, where no overlap in demand existed. These results contradict a single-capacity model, but they support the idea that the hemispheres' resource supplies are independent and have implications for both cerebral specialization and divided attention issues.     

Predicting persistence,stability, and achievement in college by major choice consistency: A test of Holland's consistency hypothesis

This study examined the relationships between students' level of consistency in choosing a major in college and their persistence, stability, and achievement in a 5-year follow-up. In contrast to the findings of most previous studies, it was found that consistent students tend to persist in college, not to change majors, and that they have higher achievement than inconsistent students. It was suggested that the current findings, which support Holland's theory, were different from the results of previous studies because of the use of behavioral definition for consistency level (actual student major choices) rather than responses to various inventories. The significance of these findings were discussed.     

Cognitive styles in the development of medical careers

Recent research has shown that academic choice and achievement may be partly a function of the student's standing on the field-dependence-independence cognitive-style dimension. The results of two longitudinal studies suggest that information about field dependence-independence may be of value for student guidance in the medical setting. The first, a study of college undergraduates who early expressed an interest in medicine, showed that these cognitive styles play a discernible role in determining who will eventually enter medical school. The second, a study of medical students, showed that field-dependent and field-independent students subsequently tend to choose different medical specialties. These results are consistent with cognitive-style theory, which proposes that field-independent people will choose vocations that require cognitive restructuring skills, whereas field-dependent people will choose vocations that require greater social-interpersonal involvement.     

The interactive effects of facial expressions of emotion and verbal messages on perceptions of affective meaning

The influence of facial expressions of emotion on perceptions of affective sentence meaning was investigated by pairing happy, angry, suprised, and sad faces of “teachers” with sentences of varying affective tone. Ninety-five students judged the overall meaning communicated by these paired stimuli. The design allowed exploration of unique facial-verbal combination effects, overall cue integration effects, and sex differences. Clear effects of cue combinations emerged. Perceived sincerity was found to be a function of the consistency of evaluative (positivity) but not dominance cues. Perceived positivity was an interactive function of both evaluative cues and dominance cues. Perceived dominance was affected by the interaction of evaluative cues. The subtleties of cue combination were clarified through open-ended dependent measures. Also, as expected, females were found to be more sensitive than males to verbal-nonverbal cue conflict in perceptions of sincerity. However, no other sex differences were found. The findings were discussed with regard to the need for a firm empirical base upon which to integrate verbal and nonverbal research traditions in the communication of affective meaning.     

An unlabeled bracketing solution to the problem of conjoined phrases in Montague's PTQ

Conclusions Although Montague claims that the system of The proper treatment of quantification in ordinary English includes some conjunction and disjunction, the rules for other grammatical constructions do not take conjunction or disjunction into account, and in general fail either syntactically or semantically when one of their arguments is so formed. Using an unlabeled bracketing of syntactic structure and recursive definitions, we have been able to rewrite the rules so that correct results are obtained.These results should provide a firmer basis for extension of PTQ.This research was supported in part by NSF Grants GS-31309 and BNS 76-23840. Our observations were made with the aid of several computer programs for PTQ: a sentence generator for the bracketed syntax, a parser, and a translator. I should like to thank Philip Tedeschi, David Warren, and David Lewis for helpful discussions. Warren is also acknowledged as co-author of the section on the semantic role of conjunction.     

A view of the background of Freudian theory.

A major concern of nineteenth century scientists was to delineate the objective units or entities with which science deals. While some philosophers of science abandoned the search as futile and tried to redefine science, investigators in the biological sciences and the sciences of man attempted to discover new entities upon which to base their disciplines. A new understanding of hypnotism gave Freud the opportunity to isolate objective entities within the mind and to found a psychology on that basis.
