Individual differences in adult decision-making competence

The authors evaluated the reliability and validity of a set of 7 behavioral decision-making tasks, measuring different aspects of the decision-making process. The tasks were administered to individuals from diverse populations. Participants showed relatively consistent performance within and across the 7 tasks, which were then aggregated into an Adult Decision-Making Competence (A-DMC) index that showed good reliability. The validity of the 7 tasks and of overall A-DMC emerges in significant relationships with measures of socioeconomic status, cognitive ability, and decision-making styles. Participants who performed better on the A-DMC were less likely to report negative life events indicative of poor decision making, as measured by the Decision Outcomes Inventory. Significant predictive validity remains when controlling for demographic measures, measures of cognitive ability, and constructive decision-making styles. Thus, A-DMC appears to be a distinct construct relevant to adults' real-world decisions.     

Individual differences in athletes' perception of expressive body movements

ObjectivesUnderstanding others' actions depends on the observer's individual characteristics and sensorimotor experience. Motor performance domains, such as sports and the performing arts, provide optimal situations to investigate the determinants of action perception. We investigated athletes' perceptual identification of expression intensity in body movements.DesignA within-subjects design was used.MethodParticipants watched point-light displays (1000 ms long) depicting expressive and inexpressive dance movements. The task was to identify the dancer's intended expression intensity.ResultsThe results indicate that expressive body movements can be reliably identified, with judgement accuracy correlating with self-report empathy indices, intuitive/deliberate decision-making preferences, and indices of sports training. Only years of sports training could predict perceptual identification accuracy.ConclusionsWe discuss the findings in relation to motor and cognitive–emotional contributions to action simulation. The potential of cross-domain transfer of motor expertise for boosting perceptual judgements and a hierarchical role of factors eliciting action simulation are also outlined.     

Individual differences in need for cognition and decision-making competence among leaders

When making decisions, people sometimes deviate from normative standards. While such deviations may appear to be alarmingly common, examining individual differences may reveal a more nuanced picture. Specifically, the personality factor of need for cognition (i.e., the extent to which people engage in and enjoy effortful cognitive activities; Cacioppo & Petty, 1982) may moderate decision makers’ susceptibility to bias, as could personality factors associated with being a leader. As part of a large-scale assessment of high-level leaders, participants completed a battery of decision-making competence and personality scales. Leaders who scored higher on need for cognition performed better on two of four components of a decision-making competence measure: framing and honoring sunk costs. In addition, the leader sample performed better than published controls. Thus, both individual differences in need for cognition and leadership experience moderate susceptibility to decision biases. Implications for broader theories of individual differences and bias are discussed.     

Sex differences in expressive drawing

We examined sex differences in expressive drawings produced by 105 boys and 105 girls aged 9-15 years. The drawings were classified according to the type of expressive strategy used to depict emotion (literal, content, abstract, or any combination of these), and rated according to the complexity of that strategy. A creative/divergent thinking task (figural form) was used to assess the relationship between expressive drawing and figural creativity. As predicted, girls scored higher than boys on the expressive drawing task. Specifically, girls relied less often on literal strategies alone and were more likely to combine literal expression with metaphorical (content and abstract) expression than boys. There was a linear relationship between expressive drawing and divergent thinking scores. These results are consistent with the idea that boys and girls differ in the expressive component of emotion, and suggest that these sex differences extend to the expressive drawing domain. They also suggest that divergent thinking may be involved in the ability to draw expressively.     

Obese-normal differences in the self-monitoring of expressive behavior

Several recent studies have found that while the behavior of normal weight individuals is primarily determined by internal cues, the behavior of the obese is chiefly controlled by external or environmental cues. The present study sought to generalize this finding to the self-monitoring of expressive behavior. Specifically, it was predicted that obese persons would tend to be high in the self-monitoring of their expressive behavior while individuals of normal weight would tend to monitor their expressive behavior to a lesser extent. This hypothesis was strongly supported. The findings are discussed both in terms of further extending the Schachterian model and in terms of the obese as a deviant population.     

Language and hand: The dimension of referential competence1

Kinesic and verbal performance data were collected for two groups of women college seniors chosen to represent extremes in a type of verbal ability termed here referential competence. This ability is conceptualized in terms of degree of integration of symbolic and ikonic representation systems, i.e., the strength of the symbol-referent links in semantic memory. A criterion measure of referential competence was developed using deviation of color naming from word-reading times on the Stroop Color-Word test. Referential competence was shown to be statistically as well as conceptually unrelated to both the standard verbal intelligence and fluency measures, and to cognitive style. During a five-minute videotaped monologue about a personal experience, persons high in referential competence produced verbal material which was specific, vivid, and objective; in contrast to the subjective and general material of the low referential group; and also produced approximately three times as many object-focused hand movements, linked to rhythm and intonation patterns of speech but largely without decipherable content. The results suggest that motor schema have a continuing intrinsic role in mature speech production, related to structure rather than content of language.     

Individual differences in the acquisition of non‐linguistic audio‐visual associations in 5 year olds

Audio‐visual associative learning – at least when linguistic stimuli are employed – is known to rely on core linguistic skills such as phonological awareness. Here we ask whether this would also be the case in a task that does not manipulate linguistic information. Another question of interest is whether executive skills, often found to support learning, may play a larger role in a non‐linguistic audio‐visual associative task compared to a linguistic one. We present a new task that measures learning when having to associate non‐linguistic auditory signals with novel visual shapes. Importantly, our novel task shares with linguistic processes such as reading acquisition the need to associate sounds with arbitrary shapes. Yet, rather than phonemes or syllables, it uses novel environmental sounds – therefore limiting direct reliance on linguistic abilities. Five‐year‐old French‐speaking children (N = 76, 39 girls) were assessed individually in our novel audio‐visual associative task, as well as in a number of other cognitive tasks evaluating linguistic abilities and executive functions. We found phonological awareness and language comprehension to be related to scores in the audio‐visual associative task, while no correlation with executive functions was observed. These results underscore a key relation between foundational language competencies and audio‐visual associative learning, even in the absence of linguistic input in the associative task.     

Individual differences in children's mathematical competence are related to the intentional but not automatic processing of Arabic numerals

In recent years, there has been an increasing focus on the role played by basic numerical magnitude processing in the typical and atypical development of mathematical skills. In this context, tasks measuring both the intentional and automatic processing of numerical magnitude have been employed to characterize how children’s representation and processing of numerical magnitude changes over developmental time. To date, however, there has been little effort to differentiate between different measures of ‘number sense’. The aim of the present study was to examine the relationship between automatic and intentional measures of magnitude processing as well as their relationships to individual differences in children’s mathematical achievement. A group of 119 children in 1st and 2nd grade were tested on the physical size congruity paradigm (automatic processing) as well as the number comparison paradigm to measure the ratio effect (intentional processing). The results reveal that measures of intentional and automatic processing are uncorrelated with one another, suggesting that these tasks tap into different levels of numerical magnitude processing in children. Furthermore, while children’s performance on the number comparison paradigm was found to correlate with their mathematical achievement scores, no such correlations could be obtained for any of the measures typically derived from the physical size congruity task. These findings therefore suggest that different tasks measuring ‘number sense’ tap into different levels of numerical magnitude representation that may be unrelated to one another and have differential predictive power for individual differences in mathematical achievement.     

Individual differences in Pollyannaism

The Pollyanna Principle states that people process pleasant information more accurately and efficiently than less pleasant information. This study examined whether different measures of Pollyanna tendencies are correlated with each other. Fourteen measures of Pollyannaism were derived for 133 students. The results showed that subjects who rated themselves as optimistic or happy also showed Pollyannaism on other measures of happiness, believed that the events in their lives were pleasant, gave themselves positive ratings on personality characteristics, recalled pleasant words more often than unpleasant words, supplied more free associations to pleasant stimuli than to unpleasant stimuli, listed pleasant items first, and judged that pleasant words were more frequent in the English language.     

Individual differences in the acceptance of stereotyping

Previous research has documented individual differences in a range of constructs relating to social stereotyping, prejudice, and intergroup attitudes. However, research has not sought specifically to measure a general acceptance of social stereotyping. In the present research, we explored attitudinal, cognitive, emotional, and personality correlates of a person’s self-reported willingness to rely on stereotypical information when interacting with people of different social and cultural groups. In six studies (N = 1080) we found that more acceptance of stereotyping was associated with more explicit and implicit stereotyping of particular groups, less liberal gender-role values, more authoritarian attitudes, preference for hierarchies, higher social dominance orientation, less universal outlook, less complexity in describing others’ emotions, less utilization of emotional information, and more utilization of social categories (gender and race) when rating the similarity of faces, less agreeable and more agentic personality, and more rigid and simplistic cognitive style (all independent of one’s gender). Female and African-American participants were less accepting of stereotyping than male and Caucasian participants. The general tendency to accept stereotyping in daily life is a measurable individual difference that may prove useful in social-personality research.
