The semantic congruity effect: Some tests of the expectancy hypothesis

Subjects comparing items in memory along some dimension are usually quicker to specify the lesser (than the greater) of two low magnitude items and the greater (than the lesser) of two high magnitude ones. One account explains this congruity effect as due to subjects instructed to specify the higher as expecting high magnitude items to follow and the reverse being true for subjects specifying the lesser. Three experiments tested this expectancy hypothesis. In experiment 1, subjects were set to the actual size range of each pair before the pair was shown but the congruity effect still occurred. In experiments 2 and 3, subjects compared critical pairs from a narrow size range plus more from either the same or much broader ranges. Times to compare the critical pairs were the same regardless of the range of the other pairs that subjects were exposed to. These results are strong evidence against the expectancy hypothesis.     

Focus shift and individual differences in the Sternberg memory-search task

One consistent finding in research using the memory search task developed by Sternberg (1966) is that negative set size has no effect on search reaction time, even when the negative set contains fewer items than the positive set. Such inefficient behavior appears to result from an intense positive focus generated by standard memory search task instructions. The present research was designed to explore the conditions under which a subject will switch focus to a smaller negative set. Two experiments were carried out using standard Sternberg instructions. The first experiment examined the effects of making the contents of the negative set explicit. The result was a shift to negative focus when the negative set was much smaller than the positive set. In the second experiment the size of the positive set was increased systematically to induce a shift to negative focus. The second experiment also examined the relationship between focus shift and measures of intelligence (Raven Progressive Matrices) and information storage capacity (digit span). The results are evidence that negative set size can affect reaction time in the memory search task, and that individual differences in ability to shift focus are related to intelligence.     

Sex differences in the levels of generality of values/preferences related to work

The current literature on sex differences in values/preferences related to work appears polarized around two apparently contradictory sets of findings and conclusions. One set of studies fails to detect sex differences. The other set of studies indicates that males are more concerned about money, independence, security, and career goals, while females appear more concerned about people and environmental issues at work. Following W. D. Siegfried, I. MacFarlane, D. B. Graham, N. A. Moore, and P. L. Young (Journal of Vocational Behavior, 1981, 18, 30–42) it is suggested that level of analysis may be a crucial factor accounting for much of the prevailing confusion in the literature. This study investigated sex differences in values/preferences related to work at various levels of generality. A sample of 1081 senior high school students was administered the Work Aspect Preference Scale (WAPS). Complete-link cluster analyses were performed for males and females separately. Comparison of the two dendrograms reveals the substantial similarity of the preference patterns of males and females. However, the basic difference in the patterns focused on the Altruism and Physical Activity subscales. Females appeared more likely to associate helping others with personal achievement whereas males tended to see helping people in terms of controlling and organizing them. Females also linked physical activity with helping others and self-development whereas males tended to associate physical activity with extrinsic rewards of work. It is concluded that the use of cluster analysis techniques may provide the best procedure to effect an adequate reconciliation of the conflicting results to be found in the current literature.     

Assessment of social anxiety: a controlled comparison among social phobics,obsessive-compulsives,agoraphobics, sexual disorders and simple phobies

The construct validity of the Willoughby Personality Schedule (WPS) as an index of social anxiety was established in the present study. The WPS correctly identifies social phobics from controls in 88% of the cases.     

Distribution of visual attention over space

Subjects viewed 3 X 3 grids in which different subsets of the nine squares were designated as "figure," either by physical shading of those squares or by a verbal instruction to imagine those squares as shaded. The time taken by participants to respond "on" or "off" the figure was measured for single or multiple probe dots, which all appeared on or off the figural subset together, and which had already been shown to be equally detectable against shaded or unshaded squares and in all nine locations within the grid. In contrast to the set-size effect generally found in experiments on memory scanning, reaction time did not necessarily increase with the number of squares in the figural subset. Instead, the critical variable, which in previous research may often have adventitiously covaried with set size, was the spatial compactness of the subsets (as indexed by square-root-area over perimeter): Probes of less compact figures required more time to classify correctly. Subjects were evidently more successful in confining their attention to sets of mutually proximal items. Reasons are given for believing that this principle may also apply in the more abstract representational or semantic spaces that determine reaction times and errors in various other cognitive tasks.     

The effect of mood and incentives on helping: Are there some things money can't buy?

Happy, guilty, and neutral mood states were induced in participants who were then provided with an opportunity to donate blood for free, to donate in exchange for $5, or to choose between donating for free or for $5. As expected, there was a significantly higher incidence of helping when subjects felt happy and guilty as opposed to emotively neutral. Contrary to predictions, helping was unaffected by the type of incentive (donate for $5, donate for free, choose $5/free) subjects were offered in interaction with their mood state. However, the type of incentive did seem to influence the postdonation emotions of subjects: Guilty subjects who donated for money felt significantly less guilty following donation than prior to it and happy subjects felt more self-altruistic (kind and generous) following donation when they helped for free. The results are discussed in terms of Cialdini's negative state relief model (for negative moods) and the intrinsic qualities of helping (for positive moods).     

Social anxiety and receptivity to interpersonal evaluation

Reactions to interpersonal evaluation were investigated among subjects chronically low and high in social anxiety, or shyness. Both groups of subjects expressed more positive affect after receiving favorable than after receiving unfavorable evaluations, supporting a “self-esteem” prediction. However, support for a “self-consistency” viewpoint was also found. In particular, low social anxiety individuals expressed more negative affect (anger) following negative than following positive feedback, while high social anxiety individuals expressed more unpleasant affect (distress) following positive than following negative interpersonal feedback. Additionally, low social anxiety subjects were alone in derogating the accuracy of negative feedback; high social anxiety individuals were indiscriminate in rating the two types of feedback as equally accurate. The role of interpersonal evaluation in the maintenance of social anxiety was discussed briefly.     

Hierarchical factor solution of coding and planning processes: Any new insights?

Hierarchical factor solution was used in the present paper in order to examine if two coding processes, simultaneous and successive, would load on a general 2nd level factor. It was further used to test if the coding processes and a factor representing planful behavior will not share the same general factor, revealing their relative independence as expected from a theoretical model of cognitive functions. Results supported the grouping of the coding tasks within a general factor, as well as the emergence of two general factors, one each for coding and planning. Further correlational evidence supported the relative independence of these two kinds of cognitive processes. These findings were discussed in the context of a general factor of intelligence.
