Individual differences in impulsive choice and timing in rats

Individual differences in impulsive choice behavior have been linked to a variety of behavioral problems including substance abuse, smoking, gambling, and poor financial decision-making. Given the potential importance of individual differences in impulsive choice as a predictor of behavioral problems, the present study sought to measure the extent of individual differences in a normal sample of hooded Lister rats. Three experiments utilized variations of a delay discounting task to measure the degree of variation in impulsive choice behavior across individual rats. The individual differences accounted for 22-55% of the variance in choice behavior across the three experiments. In Experiments 2 and 3, the individual differences were still apparent when behavior was measured across multiple choice points. Large individual differences in the rate of responding, and modest individual differences in timing of responding were also observed during occasional peak trials. The individual differences in timing and rate, however, did not correlate consistently with individual differences in choice behavior. This suggests that a variety of factors may affect choice behavior, response rate, and response timing.     

How anxious and avoidant attachment affect romantic relationship quality differently: A meta‐analytic review

Adult attachment has been studied as an important predictor of romantic relationship quality in many empirical studies. This meta‐analysis quantitatively summarized the associations between the two insecure adult attachment dimensions, anxiety and avoidance, and cognitive, emotional, and behavioral indicators of romantic relationship quality based on 73 previous studies with 118 independent samples of 21 602 individuals. More importantly, we examined the different effects of anxiety and avoidance on relationship quality. We also tested the potential moderating effects of gender on the strength of these associations. Meta‐analytic results confirmed that both anxiety and avoidance were detrimental to the cognitive, emotional, and behavioral aspects of relationship quality. Compared with anxiety, avoidance was more negatively associated with general satisfaction, connectedness, and general support in relationships. In contrast, anxiety was more positively associated with general conflict in relationships. The moderating effect of gender was weak. However, supplementary analyses found that the type of couple interaction measures (self‐report versus observation) significantly moderated the relations between insecure attachments and the behavioral indicators of relationship quality. Our results integrate and extend previous findings about the dynamics of adult attachment and romantic relationship quality. Copyright © 2012 John Wiley & Sons, Ltd.     

Does the Candidate Matter? Comparing the Voting Choice of Early and Late Deciders

Candidate personality traits have long been recognized as influential in the determination of voting choice. However, little is understood of how the perception of candidates' traits influences different categories of voters. Based on a large‐scale electoral‐panel survey (ITANES, ITAlian National Election Studies), the present study investigated whether the voting choice of early and late deciders differentially relied on candidate traits. Results showed that after considering the influence of ideology and economy assessment, candidate traits still influenced the voting choice of early deciders and, even more, of late deciders. However, while early deciders took into account both incumbent and challenger traits, late deciders mainly relied on incumbent traits. Political sophistication moderated this effect, with high‐sophisticated early deciders relying even more on the challenger, and low‐sophisticated late deciders relying even more on the incumbent. The distinction between incumbent and challenger is discussed as a key variable in explaining the role of candidate traits in the choice of voters differing as to voting decision time and political sophistication.     

Men’s personality and women’s perception of their dance quality

Recent research shows that women judge men who show variability in their body movements as good dancers. Here we report data on women’s perception of dance quality in 48 men, aged 18-42 years, and relate them to men’s self-reported personality traits. Male participants completed a standardised personality inventory (the NEO-FFI) and then danced to a basic rhythm while their body movements were tracked with optical 3D motion-capture technology. Dance movements were applied to a featureless virtual humanoid character and judged on their dance quality by 53 women, aged 17-57 years, who viewed 15 s of the rendered video clips of each male dancer. Conscientiousness and social agreeableness was correlated positively and significantly with women’s perception of men’s dance quality. Extraversion showed a positive correlation and neuroticism and openness were associated negatively with women’s perception of men’s dance quality, though these correlations failed to reach significance. We suggest that male dance movements may convey aspects of their personality, though possible consequences in terms of female mate preferences and selection remain to be explored.     

How context shapes category inferences and attribute preference for new ambiguous products

Extant research suggests that when marketers introduce products with functions that span multiple categories, consumers tend to generate beliefs in line with only a single category. This has been regarded as a major marketing challenge because it leads consumers to ignore key attributes from the product's supplementary category. Contrary to this prediction, the authors find that because consumers tend to classify new hybrid products by contrasting them against the competitive context, attributes from the supplementary category become more salient and thus contribute greater utility in choice. The authors pit the strength of this effect against several of the most dominant and favored category cues. The results confirm that classification inferences and attribute preference for new hybrid products are highly contextual, and as such, single category inferences need not translate directly into attribute preference.     

Context effects in multi-alternative decision making: empirical data and a Bayesian model

For decisions between many alternatives, the benchmark result is Hick's Law: that response time increases log-linearly with the number of choice alternatives. Even when Hick's Law is observed for response times, divergent results have been observed for error rates-sometimes error rates increase with the number of choice alternatives, and sometimes they are constant. We provide evidence from two experiments that error rates are mostly independent of the number of choice alternatives, unless context effects induce participants to trade speed for accuracy across conditions. Error rate data have previously been used to discriminate between competing theoretical accounts of Hick's Law, and our results question the validity of those conclusions. We show that a previously dismissed optimal observer model might provide a parsimonious account of both response time and error rate data. The model suggests that people approximate Bayesian inference in multi-alternative choice, except for some perceptual limitations.     

Asymmetric option effects on ease of choice criticism and defense

Individuals often criticize others’ choices and seek to defend their own. In theory, the ease of criticizing a particular choice should correspond to the ease of defending it. However, we demonstrate that differences in the types of arguments put forth in choice criticism and defense result in a systematic discrepancy in the ease with which these tasks are performed. Specifically, criticism arguments tend to be based on norms or conventions, and defense arguments on idiosyncratic tastes or circumstances; accordingly, whether the chosen option is perceived as un/conventional has a significantly greater effect on the ease of choice criticism than on the ease of choice defense. Furthermore, assessing the ease of choice defense increases the choice share of unconventional options, whereas judging the ease of choice criticism has only a small impact on choice. We discuss the implications of our findings with respect to research on reason-based choice in socially-intensive environments.     

Individual differences in women's perceptions of other women's dominance

Recent research on men's dominance perception suggests that the extent to which men perceive masculine men to be more dominant than relatively feminine men is negatively correlated with measures of their own dominance. In the current studies, we investigated the relationship between indices of women's own dominance and their perceptions of other women's facial dominance. Women's own height and scores on a dominance questionnaire were negatively correlated with the extent to which they perceived masculine women to be more dominant than relatively feminine women. In follow‐up studies, we observed similar individual differences when (i) women separately judged other women's social and physical dominance, suggesting that individual differences in women's dominance perceptions generalize across two different types of dominance judgment and (ii) we assessed the perceivers' dominance indirectly by using a questionnaire that measures the extent to which women view interactions with other women in competitive terms. These findings present new evidence that the extent to which people perceive masculine individuals to be more dominant than relatively feminine individuals is negatively correlated with measures of their own dominance and suggest that competition and conflict among women may have shaped individual differences in women's dominance perception.

Instance‐based Learning: A General Model of Repeated Binary Choice

A common practice in cognitive modeling is to develop new models specific to each particular task. We question this approach and draw on an existing theory, instance‐based learning theory (IBLT), to explain learning behavior in three different choice tasks. The same instance‐based learning model generalizes accurately to choices in a repeated binary choice task, in a probability learning task, and in a repeated binary choice task within a changing environment. We assert that, although the three tasks are different, the source of learning is equivalent and therefore, the cognitive process elicited should be captured by one single model. This evidence supports previous findings that instance‐based learning is a robust learning process that is triggered in a wide range of tasks from the simple repeated choice tasks to the most dynamic decision making tasks.
