An integration of shifts toward risk and caution in gambling situations

Findings have been reported and replicated indicating group-induced caution at the racetrack and group-induced risk in blackjack gambling. The present research examined the effects of two consistent differences between the blackjack and racetrack situations: (a) the amount of money available to groups versus individuals; and (b) the number of bets made in the postbaseline session. It was found that group-induced caution can occur in the blackjack setting if groups have larger stakes than individuals, as was the case in the racetrack studies, and that this effect disappears over trials, due to group versus individual differences established in the previous blackjack studies. Since current explanations of choice shifts cannot account for the observed trial effects, it was suggested that traditional choice-dilemma material, on which these explanations are largely based, be examined for such effects. Implications of the possible outcomes of such an examination for current group polarization theory were discussed.     

How to reverse the vicious cycle of low self-esteem: The importance of attentional focus

Recent research suggests that the cognitive processes of low self-esteem people (low SEs) perpetuate low self-esteem and its undesirable emotional and behavioral correlates. For instance, it has been suggested that low SEs are more “self-conscious” than high self-esteem people (high SEs) and that self-consciousness can impair task performance. It was reasoned that if low SEs were led to focus their attention away from themselves and onto the task, performance would improve relative to high SEs. In a 2 × 3 between-subjects factorial design, subjects high and low in chronic self-esteem performed a concept formation task under three conditions: (1) in the presence of an audience, where self-focused attention is presumably high; (2) in a control group, in which attention was not manipulated; and (3) with instructions to concentrate on the task diligently. A significant interaction effect was obtained, indicating that low SEs performed worse than high SEs in the audience condition (p < .025), no differently in the control, and better than high SEs (p < .01) when instructed to concentrate on the task. Although the latter results are unusual in the context of self-esteem research, they are strikingly parallel to recent findings in the study of test anxiety.     

Anxiety and sex role in body landmark functions

Two hypotheses were evaluated. One proposed that the more prominent a body landmark the less anxiety will be evoked by a theme linked to that landmark. The relation was determined between landmark prominence and anxiety evoked by a taped message appropriate to the landmark-linked theme. Two female samples were studied. The findings supported the hypothesis. A second hypothesis proposed that enhancing awareness of body landmarks under threat conditions is positively related to degree of masculinity and negatively related to degree of femininity. Changes in landmark awareness during appropriate taped messages were studied in two male and two female samples. Masculinity-femininity was also measured. The findings were particularly supportive of the hypothesis relating masculinity to mobilization of landmarks.     

Categorical and schematic organization and the development of retrieval strategies

This study investigated the effects of schematic and categorical organization on young children's recall. Preschool and kindergarten children recalled either a taxonomic list or a story in one of two presentation conditions: an alternate condition, in which the material was presented, children recalled it and the procedure was repeated, or a successive condition in which the material was presented twice and children recalled it twice. Although preschool children's story recall was well organized, their list recall was poorly organized, and organization did not increase over recall trials in either presentation condition. In contrast, kindergarten children's recall of both the story and the list was well organized, and their recall was better organized on the second recall trial than on the first in both presentation conditions. These results are discussed in terms of the development of retrieval strategies during the preschool years/     

Sequencing strategies in children 18–24 months: Limitations imposed by task complexity

Researchers have generally reported that very young children lack the orderly, sequential approach to tasks that characterizes skilled action. This study questions that assumption by investigating to what extent deficits in sequencing are a function of task complexity (type and number of elements), and to what extent sequencing ability is tied to competent task performance. Three tasks—the Lock Box, Pegboards, and Object Grouping—were each presented in two forms, varying only in number of elements. Participants were 38 children between 18 and 24 months of age. The Denver Developmental Screening Test was also administered to all children. When number of task elements increased, there was a dramatic decrease in orderliness of approach. Type of task served to exaggerate or minimize these effects. However, irrespective of task complexity, children used a consistent pattern of organization, generally two or three sequential movements. This strategy, though serving well for tasks of limited dimensions, was inadequate for tasks with more than four or five elements. Sequencing skills, as well as other aspects of performance, were significantly correlated with Denver scores. Results suggest that exceeding the limits of young children's organizing abilities may obscure actual capacities. The role of task complexity in the performance of young children is discussed as it relates to developmental processes, clinical assessment, and teaching.     

Convergence between attention variables and factors of psychometric intelligence in older adults

The purpose of the present study was to examine the hypothesis that individual differences on measures of attention would converge with select factors of psychometric intelligence, especially fluid intelligence and short-term acquisition and retrieval. A sample of 83 elderly adults $\text{(}\text{X}\text{= 71}\text{years}\text{)}$ was administered a battery of 17 psychometric ability tests. Tests were selected to mark four psychometric ability factors (Cattell and Horn's dimensions of fluid and crystallized intelligence, short-term acquisition and retrieval, and perceptual speed). Also, seven tasks representing four aspects of attention—decoding processes, selective attention, attention switching, and concentration—were administered. A confirmatory factor analysis was conducted to examine the relationships among the four psychometric ability factors and 11 variables obtained from the attention tasks. Results were only partially consistent with the hypothesized pattern of convergence. Two attention measures had significant loadings on a fluid-type intelligence factor, and one had a marginally significant loading on a short-term memory factor. In general, the greatest convergence occured between attention variables and the ability factor of Perceptual Speed. Results were discussed with respect to previous research on psychometric abilities and cognitive processes, the theory of fluid-crystallized intelligence, and their implications for understanding intellectual aging.     

The other way around: Effects of causal attributions on estimates of consensus,distinctiveness, and consistency

It was hypothesized that the attributed cause of a given person's behavior will affect inferences about its generalizability over persons (consensus), stimuli (distinctiveness), and circumstances (consistency). Moreover, these effects were expected to parallel the effects of consensus, distinctiveness, and consistency information on causal attributions. Experiment 1 provided support for these predictions but also showed that attribution affected consensus judgments less than it affected judgments of distinctiveness and consistency, particularly when consensus was not the first characteristic estimated. Using a different set of stimulus materials and a different manipulation of attribution, Experiments 2 and 3 provided further evidence for the effects of attribution on inferences of consensus information. Experiment 3 indicated that the false consensus effect—actors' tendency to assume that the majority of people share their behavior—may be due to actors' tendency to attribute their behavior to situational factors. Implications of the present studies for biased estimates of consensus and the use of consensus and attribution as mediating variables are discussed.     

Korsakoff amnesic syndrome: The result of simultaneous deficits in several independent processes?

Alcoholic Korsakoff patients were presented six verbal list learning tasks (two denotatively and three connotatively organized, and one high-imagery word list). Twelve recall trials and three recognition probes were obtained per list. Results indicate that for Korsakoff patients, (1) recall varied with list organization, (2) recognition memory although poor was further disrupted by proactive inhibition only on denotatively categorized lists, and (3) conceptual deficits disrupted ability to appreciate simple dichotomies in denotatively categorized lists. It is hypothesized that the joint presence of deficts in specific conceptual and semantic processes in necessary although perhaps not sufficient to produce a Korsakoff amnesia.     

The structure of coordination in first language acquisition of Mandarin Chinese: evidence for a universal

This study exemplifies a type of cross-linguistic research which is based on the theory that certain parameters of natural language variation are central to the human competence for language. Sensitivity to these parameters allows the child to develop various specific language structures which follow from setting the parameters. Results of this study provide evidence that children are universally sensitive to one such parameter, namely, Principal Branching Direction.Data are based on results of a standardized elicited imitation test of 68 Chinese children in Taiwan between 2;0 and 4;5 with mean age of 3;3. The test is on a set of coordinate sentences. The results show that children acquiring Mandarin Chinese (a left-branching language) systematically prefer VO sentences with a backward reduction pattern ([V + V]O) over those with a forward reduction pattern (V[O + O]).Children's responses to SV coordinate sentences differ systematically from their VO responses. They very frequently reduce redundant subjects in a forward direction (in SV sentences) and do not prefer backward reduction ([S + S])V) over forward reduction (S[V + V]) in these SV sentences.This paper suggests an explanation of this apparent paradox in terms of an interaction in early language acquisition between children's sensitivity to a predominant Chinese topic-comment structure (in SV) and their sensitivity to the abstract, specifically grammatical concept of “Principal Branching Direction”.
