Slow Motor Responses to Visual Stimuli of Low Salience in Autism

ABSTRACT

The authors studied 2 tasks that placed differing demands on detecting relevant visual information and generating appropriate gaze shifts in adults and children with and without autism. In Experiment 1, participants fixated a cross and needed to make large gaze shifts, but researchers provided explicit instructions about shifting. Children with autism were indistinguishable from comparison groups in this top-down task. In Experiment 2 (bottom-up), a fixation cross remained or was removed prior to the presentation of a peripheral target of low visual salience. In this gap–effect experiment, children with autism showed lengthened reaction times overall but no specific deficit in overlap trials. The results show evidence of a general deficit in manual responses to visual stimuli of low salience and no evidence of a deficit in top-down attention shifting. Older children with autism appeared able to generate appropriate motor responses, but stimulus-driven visual attention seemed impaired.     

The Joint Multivariate Modeling of Multiple Mixed Response Sources: Relating Student Performances with Feedback Behavior

The present study concerns a Dutch computer-based assessment, which includes an assessment process about information literacy and a feedback process for students. The assessment is concerned with the measurement of skills in information literacy and the feedback process with item-based support to improve student learning. To analyze students’ feedback behavior (i.e. feedback use and attention time), test performance, and speed of working, a multivariate hierarchical latent variable model is proposed. The model can handle multivariate mixed responses from multiple sources related to different processes and comprehends multiple measurement components for responses and response times. A flexible within-subject latent variable structure is defined to explore multiple individual latent characteristics related to students’ test performance and feedback behavior. Main results of the computer-based assessment showed that feedback-information pages were less visited by well-performing students when they relate to easy items. Students’ attention paid to feedback was positively related to working speed but not to the propensity to use feedback.     

First things first: infants make good use of the sympathetic rhythm of imitation,without reason or language

Research on communication with infants, including newborns, has demonstrated that imitations in great variety play many different parts, and with emotions of interest and pleasure. Matching another's actions may seek attention and provoke reply, accept or reject advances, express admiration or mockery. It seems best to regard imitating as one way that persons express and receive sympathetic awareness, one manifestation of the intuitive readiness to move rhythmically with others in games of sociability. Infants exhibit growing awareness of how to cooperate with others in gaining knowledge and skills. The intersubjective intuitions that are active early in life and that build trust and companionship must be significant for therapists who work with young patients for whom communication is difficult. Imitating and accepting imitations can build reciprocal confidence.     

Matters Olympic and Paralympic

Over the past several years, I have been arguing that nature sports such as surfing, backcountry skiing, and mountaineering are best described as sports in which athletes interact dynamically with natural features rather than compete with other humans. This article is part of a larger attempt to trace the implications of that view. Specifically, I consider the relationship between nature sports and competition. To this purpose, I address three separate, but related topics: First, I reply to Leslie Howe’s article, ‘On Competing Against Oneself, Or, I Need to Get a Different Voice in My Head’, in which she argues that there is a version of self-competition that is central to nature sports. Second, I argue that adapting nature sports to fit into formal competitive frameworks is problematic because, when we do so, the focus shifts from athletes interacting with natural features to athletes using natural features to outdo other athletes. And third, I argue that nature sports may seem competitive because the interaction between humans and natural features produces a type of intensity that is very similar to the intensity produced in competition. I argue further that because nature sports can produce this intensity in an environment that is not based on competition, they present an important alternative to traditional sports.     

Between the Horns: A Dilemma in the Interpretation of the Running of the Bulls – Part 1: The Confrontation

The essay, divided in two parts, examines the event of the running of the bulls (encierro in Spanish). The phenomenon of the encierro, a complex cultural activity of deep historical roots, demands to be understood: What drives people to risk injury or death at the horns of untamed bulls? How should we make sense of this, subjective and objectively? To answer these questions, I use a framework that relies on explanation and assessment of popular views on the way to arguing for a philosophical alternative. This arrangement is readily adaptable to many other sporting (and non-sporting) activities where risk and/or mass participation are key factors. Its unorthodox format – organised around an opening narrative of a paradigmatic, skilled and lucky run with the bulls, as well as hors texte (direct appeals to the reader) – brings the reader straight into the fray, philosophical and otherwise. Part I begins by presenting the history of the encierro. It also explains the dynamics of the event, often via images with pedagogical and critical side-commentaries. It proceeds to introduce and critically engage with prevalent explanations, most with ethnological tendencies, that conceive the running as tradition, rite, ritual and sport. This part ends with a dilemma whereby we either try to explain matters by resorting to particular and partial interpretations, or a ‘democratic’ conglomerate of superficial and confusing boundaries, or in the end we simply concede our inability to understand the phenomenon of the running of the bulls in toto. This philosophical impasse will be evaded in part 2 (Sport, Ethics and Philosophy 2, 1) via existentialist and phenomenological analysis.     

Behavioural and Emotional Development in Children of Divorce

This study reports on teacher perceptions of the impact of parental divorce on behaviour and emotional development in children of divorce. Participants were a purposive sampling of 80 primary school learners with parental divorce experience and a comparison group of 40 others from typical or intact families (n = 120: males = 64; females = 56; age range = 6 to 12 years). Teachers completed the Conners' Rating Scales—Revised (CRS—R: Conners, 1998; Casat et al., 1999) on each of the learners. The findings suggest that teachers perceive younger children from divorced parents were more likely to have emotional and behavioural challenges than those from intact families. By contrast, teachers perceived older children from intact were to have emotional and behavioural difficulties.

The effects of culture and self-construal on responses to threatening health information

Objective: The current studies examined if cultural and self-construal differences in self-enhancement extended to defensive responses to health threats.

Design: Responses to fictitious medical diagnoses were compared between Asian-Americans and European-North Americans in Experiment 1 and between Canadians primed with an interdependent versus an independent self-construal in Experiment 3. In Experiment 2, the responses of Chinese and Canadians who were either heavy or light soft drink consumers were assessed after reading an article linking soft drink consumption to insulin resistance.

Main outcome measure: The primary-dependent measure reflected participants’ defensiveness about threatening versus nonthreatening health information.

Results: In Experiment 1, all participants responded more defensively to an unfavourable than a favourable diagnosis; however, Asian-Americans responded less defensively than did European-North Americans. In Experiment 2, all high soft drink consumers were less convinced by the threatening information than were low soft drink consumers; however, among high consumers, Chinese changed their self-reported consumption levels less than did European-Canadians. In Experiment 3, interdependence-primed participants responded less defensively to an unfavourable diagnosis than did independence-primed participants.

Conclusion: Defensive reactions to threatening health information were found consistently; however, self-enhancement was more pronounced in individuals with Western cultural backgrounds or independent self-construals.     

Extreme‐Right Voting in Western Europe: The Role of Social‐Cultural and Antiegalitarian Attitudes

The joint impact of antiegalitarian attitudes and social‐cultural attitudes on citizens’ tendency to vote for extreme right‐wing political parties was investigated. In the first study, we explored these attitudes in representative samples of seven Western European countries. In a follow‐up study, we predicted respondents’ likelihood of voting for a Dutch right‐wing party on the basis of the measures of social‐dominance orientation (as an indicator of antiegalitarian attitudes) and right‐wing authoritarianism (as an indicator of social‐cultural attitudes). Our findings demonstrated that voting for extreme right‐wing parties was associated more consistently with antiegalitarian attitudes than with social‐cultural attitudes. Moreover, the effect of antiegalitarian attitudes was partly mediated by migration attitudes (Study 1) and ethnic prejudice (Study 2). We discuss the finding that antiegalitarian attitudes are more strongly related to extreme right‐wing voting than social‐cultural attitudes.
