Interhemispheric integration of compound nouns: effects of stimulus arrangement and mode of presentation

Normal subjects had to name German compound nouns which were presented tachistoscopically. The compound nouns were displayed either unilaterally to the left or right visual field or bilaterally with one element to each visual field. In the bilateral condition a distinction was made as to whether familiar or unfamiliar arrangement of the elements was used. Representation in print was compared with pictorial representation of the compound nouns. A right visual-field superiority was observed with printed representation, but no laterality effects with pictorial representation. Bilateral processing was superior to unilateral processing. Within the bilateral conditions, the familiar arrangement of the elements yielded a significantly better performance than unfamiliar arrangement. This difference can be explained by reading habits and/or by different styles of interhemispheric integration.     

The varieties of fear

Conclusion I shall conclude with a methodological moral. I have tried to show that there are several fundamentally different kinds of fear. One is a pure propositional attitude, one is partially a bodily state, and one is a relation between a person and a nonpropositional object. Other emotions come in similar varieties, such as hope and happiness, but with significant differences. The state of happiness, for example, does not entail any particular bodily state or feeling. So one lesson is this: it is hard to generalize about the emotions. Further detailed, analytical studies of particular emotions are needed before a general theory of the emotions can be fruitfully attempted.     

SELF-ASSESSED TRAINING NEEDS: THE EFFECTS OF ATTITUDES TOWARD TRAINING, MANAGERIAL LEVEL, AND FUNCTION

Self-assessment research has concentrated on validity and psychometric issues in selection and appraisal contexts. Little is known about factors that affect self-assessment of training needs. The present study examines the influence of managerial position (level, function) and managerial attitudes toward training utility on self-reported training needs. A training-needs survey consisting of items related to basic managerial, interpersonal, administrative, and quality control skills was completed by 506 lower and middle level managers across four functional areas. Correlational and regression analyses indicated that managerial level and function had some effect on reported administrative training needs, while function and attitudes towards training utility had some impact on self-reported training needs for quality control. Level, function, and attitude were not related to reported basic managerial and interpersonal training needs. The implications and limitations of the results are discussed, and future research directions are presented.     

Specific temporal-lobe signs and enhanced delayed cross-modal matching performance

Structural damage to the amygdala severely retards delayed cross-modal (tactile-to-sight) matching in primates. Conversely, we hypothesized that people who display signs suggestive of specific temporal lobe lability should show enhanced delayed cross-modal matching performance. The hypothesis was supported. In a single experiment involving 25 subjects, significant negative correlations obtained between the numbers of errors on the cross-modal matching task and numbers of affirmative responses within clusters of items that contained themes of meaningfulness, religious beliefs or ictal, complex partial epileptic (limbic) states. On the other hand, the numbers of errors were not significantly correlated with either clusters of control items or items that are presumed to reflect the function of other temporal-lobe structures. Both matching and questionnaire data were collected under double-blind conditions.     

Stress as a state of anticipatory vigilance

The pituitary-adrenocortical system is activated in stressful situations, and the adrenocortical hormones have been implicated by Selye in the diseases of stress. Evidence indicates that the adrenocortical hormones peak during the period of anticipation of stressful events, not during actual confrontation with them. The circadian cortisol rhythm shows peaks before waking, not during active periods of the day, and cortisol does not appear to be required during physical activity. The role of these hormones appears to be to suppress ongoing physiological activity in order to increase vigilance and to get the organism ready to take action before the impact of dangers.

Galef’s Transfer-of-Information Effect Occurs in a Free-Foraging Situation

Galef and his colleagues have repeatedly shown that one rat may transfer information regarding the type of food it has consumed to other conspecifics. Such experiments typically have been conducted in wire-mesh cages or a wooden maze. The present experiments sought to extend this paradigm to the open-field foraging situation having six food patches to choose from. Following interaction with a demonstrator that had consumed either a cocoa or a cinnamon diet, single observers (Experiment 1) were tested in the foraging situation. Food-consumption scores indicated that observers consumed significantly more of their specific demonstrator’s diet than a second diet that was available also. Experiment 2 involved the simultaneous testing of two observers in the foraging laboratory. In Experiment 3 two observers were once again tested, but each had been provided a different food-type message prior to foraging. Positive results, mirroring those of Experiment 1, were obtained in both Experiments 2 and 3. The results of these three experiments underscore the robustness of this phenomenon and its generalizability to other testing conditions.

     

Linking person and context in the daily stress process

In this study we combined daily diary data with interview data to investigate individual differences in the impact of stressful daily events on mood. Using a sample of 96 women in an urban community, we examined perceived neighborhood quality and major life events as possibly potentiating the effects of stressful daily events, and we viewed social supports as potentially buffering this daily process. Results confirmed that the presence of chronic ecologic stress (neighborhood perceptions) exacerbated the immediate effects of stressful daily events on mood and also increased the likelihood of enduring effects of daily stressors on next day's mood. Contrary to expectations, previous exposure to major life events decreased the impact of stressful daily events. The availability of social supports, although not buffering the impact of stressful daily events on mood, did mitigate the enduring effects of these events on next day's mood. This study also presents a method for analyzing daily time-series data, while correcting for potential problems of autocorrelated error terms. As such, this study represents a significant advance over previous analytic approaches to time-series data in the study of the stress process.
