Questionnaire of executive function for dancers: an ecological approach

There is a current debate about the ecological validity of executive function (EF) tests. Consistent with the verisimilitude approach, this research proposes the ballet executive scale (BES), a self-rating questionnaire that assimilates idiosyncratic executive behaviors of classical dance community. The BES was administrated to 149 adolescents, students of the Cuban Ballet School. Results present a Cronbach's alpha coefficient of .80 and a split-half Spearman-Brown coefficient r (SB) = .81. An exploratory factor analysis describes a bifactorial pattern of EF dimensions, with a self-regulation component, which explains more than 40% of variance, and a Developmental component, which accounts for more than 20% of variance. The questionnaire's total scores fit linear regression models with two external criteria of academic records, confirming concurrent validity. These findings support the hypothesis that the internalization of specific contextual cultural meanings has a mediating influence in the development of EF.     

Different patterns of dissociation in unilateral spatial neglect

The aim of this paper is to discuss the issue of dissociations found in unilateral spatial neglect according to the modality of space exploration and the nature of the task. For this purpose we present a reanalysis of the data from a recent paper of Gentilini et al. (1989) comparing visual and blindfolded exploration of a computer keyboard and discuss the performance of a left-brain-damaged patient with right visuospatial neglect and left-sided neglect dyslexia. We conclude that unilateral spatial neglect cannot be interpreted as a disruption of a single attentional mechanism, but rather it reflects impaired attentional mechanisms at several levels of cognitive processing.     

Visual encoding of patterns is subject to dual-task interference

Two stimuli were presented at varying stimulus onset asynchronies (SOAs), with each stimulus associated with a distinct task. The first stimulus was a tone at one of either two or three frequencies. In two conditions, the task associated with a tone was either a speeded two-alternative discrimination (2AD), or a speeded three-alternative discrimination (3AD) based on the pitch of the tone. In a third condition, subjects were told to ignore the tone. The second stimulus was a briefly exposed study matrix of red and black squares followed by a mask. After a fixed delay, the mask was replaced by a test matrix that was either the same or different from the study matrix. The task associated with the matrices was to indicate, with no speed pressure, whether the study matrix and the test matrix were the same or different. Results from each speeded AD condition showed that subject's accuracy in the matrix task decreased as the SOA between the tone and the study matrix decreased. This effect was larger for the 3AD tone task than with a 2AD tone task. In addition, within each speeded AD condition, longer RTs in the tone task were associated with lower accuracy in the matrix task. None of these effects was evident when the subjects were told to ignore the tone. These results suggest that encoding visual information can be subject to significant capacity limitations imposed by cross-modal multitasking.     

Teaching and Cultural Otherness

This work focuses on the relational dimension of the encounter between teacher and students meant as a structural element for teaching practice. By using theoretical group-analytical and anthropo-analytical coordinates, the authors psychodynamically problematize some relational conditions that may influence learning. This research concentrates on the circumstances that limit and allow the birth of a group arrangement capable to learn from experience, rather than on a perspective to teach-learn in a perfect agreement with planning. Intercultural education is pointed out and located as a horizon and ideal term to guide educational practice.     

Focusing attention on overlapping and non-overlapping figures with subjective contours

In a series of five experiments we investigated whether observers could focus attention on a restricted visual area that was demarcated by Kanizsa-like subjective contours, and whether this effect also occurred in the case of overlapping figures. The task was a simple reaction time to a luminance increment and the basic finding was that reaction time was faster when the imperative stimulus fell inside the focus of attention than when it fell outside. The first two experiments showed that the extent of the attentional focus could be adapted to a region that was demarcated by subjective contours, thus extending the results of previous studies that used regions demarcated by real contours. The last three experiments showed that, regardless of the type of margins, focusing was more efficient for the figure that was perceived as lying in front in a pair of overlapping figures.

Friendships of older men and women: exchange patterns and satisfaction

In this study we examined the relation between perceived equity of exchanges and friendship satisfaction for a sample of 110 older men and women. Respondents were interviewed concerning their relationship with their best friend and one other friend in their support network. Perceived equity was a significant predictor of friendship satisfaction only in the case of the other friend. In addition, results showed that men were involved in more equitable friendships than were women. Discussion focuses on the importance of equity consideration and gender differences in the friendships of older adults.     

New Voices for Expressive Pragmatism: Bridging the Divide between Pragmatism and Perfectionism

This article explores the theme of moral rationality by examining two distinct philosophical approaches, those of perfectionism and pragmatism broadly construed. It does this by comparing Cora Diamond's reading of J. M. Coetzee's novel The Lives of Animals with an imaginary reading of the same novel tuned to a moral sensibility closer to Deweyan pragmatism. By comparing a real account with an imaginary one, the article intends to press Diamond's perfectionist understanding of problematic moral experience into confrontation with a pragmatist account of the same phenomenon. This reading becomes the starting point for a broader confrontation between two larger philosophical conceptions: perfectionism and pragmatism. By this comparison, the article means to extend a dialogue begun more than a century ago, showing in particular that integrating both perspectives within a common moral epistemology provides new insights into our understanding of moral experience. The general claim is that their differences notwithstanding, perfectionism and pragmatism share a common moral sensibility, although they part ways on some decisive issues that the article makes explicit.     

Tracking fear in snake and spider fearful participants during visual search: A multi-response domain study

In visual search tasks snake or spider fearful participants showed shorter reaction times (RTs) to respond to their feared animal (e.g., snake) than to the nonfeared animal (i.e., spider) (Öhman, Flykt, & Esteves, 2001). Here, we used this paradigm with heart rate (HR), RTs, and event-related potential (ERP) measures, to investigate the nature of the responses to the feared animal, a nonfeared (but fear-relevant) animal, and fear-irrelevant target stimuli with snake fearful, spider fearful, and nonfearful participants. Fearful participants showed shorter RTs and evoked larger amplitudes on a late positive potential (LPP; 500–700 ms) for their feared compared to the nonfeared and the fear-irrelevant targets. No relevant significant differences were found on early ERP components and HR measures. These findings do not support an involvement of early information processing in the detection of the feared animal in fearful participants, they favour instead a more elaborated analysis of these complex stimuli to achieve the detection.
