Why we need cognitive explanations of autism

In the 70 years since autism was described and named there have been huge changes in the conceptualization of this enigmatic condition. This review takes a personal perspective on the history of autism research. The origins of the first cognitive theories of autism, theory of mind and weak central coherence, are discussed and updated to inform future developments. Selected experimental findings are interpreted in the historical context of changes that have been brought about by advances in methodology. A three-level framework graphically illustrates a causal chain between brain, mind, and behaviour to facilitate the identification of phenotypes in neurodevelopmental disorders. Cognition is placed at the centre of the diagram to reveal that it can link together brain and behaviour, when there are complex multiple mappings between the different levels.     

The impact of using forced decision-making strategies on post-decisional confidence

The impact of motivational and cognitive factors on post-decisional confidence (PDC) level was tested in two experiments. In the first experiment, subjects were first identified as having an intuitive preference toward using either a compensatory or a noncompensatory decision strategy and later on were forced to use either a compatible or a non-compatible strategy. PDC level decreased after using a noncompensatory strategy, and the decrease was higher when it was a noncompatible strategy. In a second experiment, subjects received feedback about their preferred strategy but were not later forced to use any specific strategy. Most subjects continued to utilize their preferred strategy and PDC level was not changed. Overall, intuitive PDC was not found to be sensitive to differences between compensatory and noncompensatory strategies. The result suggested that PDC is a function of an internal cost-benefit analysis which includes both cognitive and motivational factors.     

Self-esteem threat combined with exposure to thin media images leads to body image compensatory self-enhancement

This study examined the effect of a self-esteem threat combined with exposure to thin images on body image (BI) satisfaction and investment. Female participants (N = 94) received a self-esteem threat consisting of false failure feedback or received false success feedback on an intellectual task allegedly highly predictive of academic and professional success. They then viewed media images featuring thin models or products. After viewing thin models, women who had received failure feedback declared themselves more satisfied about their appearance and less invested in it than did women who had received success feedback. These results suggest that exposure to the thin ideal may inspire women experiencing self-esteem threats to use appearance as an alternative source of worth, thus maintaining their global esteem through BI compensatory self-enhancement. Potential long-term implications of this strategy, such as a paradoxical increase in BI investment and the development of eating pathology, are discussed.     

The Motivating Role of Perceived Right Violation and Efficacy Beliefs in Identification with the Italian Water Movement

Because individuals' fundamental right to water is often taken for granted, little is known about why individuals participate in water activism. We examine how individuals identify with and intend to participate in the Italian Water Movement to defend the “public management” of water supply. Building on the collective‐action literature, we test an explanatory model in which the perceived violation of the right to water and group and participative‐efficacy beliefs increase movement identification, which predicts subsequent activism. Study 1 (N = 153 activists) largely confirmed our hypotheses: right violation and participative efficacy uniquely influenced movement identification, which in turn predicted activism. Study 2 corroborated these findings by employing a broader sample of 132 Italian citizens, with right violation, participative and group‐efficacy beliefs predicting movement identification, which in turn predicted activism. We discuss the theoretical and practical implications of these findings.     

A kinematic comparison of successful and unsuccessful tennis serves across the elite development pathway

While velocity generation is an obvious prerequisite to proficient tennis serve performance, it is also the only stroke where players are obliged to negotiate a unique target constraint. Therefore, the dearth of research attending to the accuracy component of the serve is surprising. This study compared the body, racquet and ball kinematics characterising successful serves and service faults, missed into the net, in two groups of elite junior female players and one professional female tennis player. Three-dimensional body, racquet and ball kinematics were recorded using a 22-camera VICON motion analysis system. There were no differences in body kinematics between successful serves and service faults, suggesting that service faults cannot be attributed to a single source of biomechanical error. However, service faults missing into the net are characterized by projection angles significantly further below the horizontal, implying that consistency in this end-point parameter is critical to successful performance. Regulation of this parameter appears dependent on compensatory adjustments in the distal elbow and wrist joints immediately prior to impact and also perceptual feedback. Accordingly, coordination of the distal degrees of freedom and a refined perception-action coupling appear more important to success than any isolated mechanical component of the service action.     

Dual-task processing in younger and older adults: similarities and differences revealed by fMRI

fMRI was used to explore age differences in the neural substrate of dual-task processing. Brain activations when there was a 100 ms SOA between tasks, and task overlap was high, were contrasted with activations when there was a 1000 ms SOA, and first task processing was largely complete before the second task began. Younger adults (M=21 yrs) showed activation in dorsolateral prefrontal cortex and in parietal areas as well as in ventral medial frontal cortex and sub-lobar areas. Activations in older adults (M=71 yrs) did not differ significantly from younger adults except for higher activations in occipital and polar prefrontal cortex. The results were well fit by a model with two networks managing dual-task interference, a medial prefrontal network that detects changes in the stimulus situation and maps them to associated changes in the valence of response mappings and a lateral frontal-parietal network that initiates and carries out the shift from one task to the other. The additional activations in older adults as a group and the correlations of individual differences in activation with performance were consistent with recruitment within each of these networks. Alternative explanations such as hemispheric asymmetry reduction and reactive rather than proactive processing in older adults were not supported.     

“I'm Not Prejudiced,but . . .”: Compensatory Egalitarianism in the 2008 Democratic Presidential Primary

The historic 2008 Democratic presidential primary race between Barack Obama and Hillary Clinton posed a difficult choice for egalitarian White voters, and many commentators speculated that the election outcome would reflect pitting the effects of racism against sexism ( Steinem, 2008 ). Because self‐reported prejudices may be untrustworthy, we used the Implicit Association Test (IAT) to assess White adults’ (1) condemnation of prejudices, and (2) attitudes toward the candidates in relation to voting decisions, as part of an online survey. Results supported the proposed compensatory egalitarianism process, such that Whites’ voting choice was consistent with their implicit candidate preference, but in an effort to remain egalitarian, participants compensated for this preference by automatically condemning prejudice toward the other candidate's group. Additional findings showed that this process was moderated by participants’ ethnicity and level of prejudice, as expected. Specifically, compensatory egalitarianism occurred primarily among Whites and individuals low in explicit prejudice. Implications for candidate support, aversive racism theory, and implicit compensation processes are discussed.

Fired Up by Morality: The Unique Physiological Response Tied to Moral Conviction in Politics

Studies provide mounting evidence that morally convicted attitudes elicit passionate and unyielding political responses. Questions remain, however, whether these effects occur because moral conviction is another strong, versus a distinctly moral dimension of attitude strength. Building on work in moral psychology and neuroscience, I argue that moral conviction stems from a distinctive mode of mental processing that is tied to automatic affective reactions. Testing this idea using a lab experiment designed to capture self‐reported moral conviction and physiological arousal, I find that conviction about political objects positively predicts arousal evoked by the objects, while attitude extremity and importance do not. These findings suggest that moral conviction items do tap into moral processing, helping to validate the conviction measure. They also illustrate the value of using physiological indicators to study politics, help explain why morally convicted attitudes trigger such fervent responses, and raise normative questions about political conflict and compromise.     

Moral Conviction and Political Engagement

The 2004 presidential election led to considerable discussion about whether moral values motivated people to vote, and if so, whether it led to a conservative electoral advantage. The results of two studies—one conducted in the context of the 2000 presidential election, the other in the context of the 2004 presidential election—indicated that stronger moral convictions associated with candidates themselves and attitudes on issues of the day uniquely predicted self-reported voting behavior and intentions to vote even when controlling for a host of alternative explanations (e.g., attitude strength, strength of party identification). In addition, we found strong support for the hypothesis that moral convictions equally motivated political engagement for those on the political right and left and little support for the notion that a combination of morality and politics is something more characteristic of the political right than it is of the political left.
