The desire to lose one's identity

The desire to merge identities with an intimate partner was found to be negatively related to psychoticism but related to other social desires, such as the desire for physical closeness and identifying with the achievements of others.     

ACOUSTIC ANALYSIS OF ORAL PRODUCTIONS OF INFANTS LATER DIAGNOSED WITH AUTISM AND THEIR MOTHER

Research on early signs of autism in social interactions often focuses on infants’ motor behaviors; few studies have focused on speech characteristics. This study examines infant‐directed speech of mothers of infants later diagnosed with autism (LDA; n = 12) or of typically developing infants (TD; n = 11) as well as infants’ productions (13 LDA, 13 TD). Since LDA infants appear to behave differently in the first months of life, it can affect the functioning of dyadic interactions, especially the first vocal productions, sensitive to expressiveness and emotions sharing. We assumed that in the first 6 months of life, prosodic characteristics (mean duration, mean pitch, and intonative contour types) will be different in dyads with autism. We extracted infants’ and mothers’ vocal productions from family home movies and analyzed the mean duration and pitch as well as the pitch contours in interactive episodes. Results show that mothers of LDA infants use relatively shorter productions as compared to mothers talking to TD infants. LDA infants’ productions are not different in duration or pitch, but they use less complex modulated productions (i.e., those with more than two melodic modulations) than do TD. Further studies should focus on developmental profiles in the first year, analyzing prosody monthly.     

The Conceptualisation and Measurement of Pacing Styles

Pacing style reflects how individuals distribute their effort over time in working toward deadlines. As a new construct introduced in 2002, the notion of pacing style has intuitive appeal, but has been under‐researched, in part, due to a measurement need. Therefore, the purpose of this research was to improve the conceptualisation of pacing style and to develop and validate a new scale‐based measure. The result was the nine‐item Pacing Action Categories of Effort Distribution (PACED), consisting of deadline (complete work in a short time period just before the due date), steady (spread task activities evenly over time), and U‐shaped (invest most of the effort at the start and finish of a task, with a break in between) action styles. Across eight independent samples of students, faculty, and organisational employees, we examined the dimensionality, internal consistency, stability (temporal and situational), and validity (construct, convergent, discriminant, predictive) of PACED. Results support the use of PACED as a reliable and valid measure, and we discuss several research avenues that would benefit from incorporating the concept of pacing style.     

Adolescents and Microcomputers: Sex Differences,Proxemics, Task and Stimulus Variables

Questionnaires concerning attitudes toward use of microcomputers at home, in school, and at video arcades were administered to 879 high school students. Direct observations of adolescent proxemics and sex differences, and of various parameters of video games in 18 video arcades were made. A thorough and representative content analysis of sex bias of microcomputer software advertising brochures was carried out. Results supported previous findings of overrepresentation of masculine culture in the adolescent world of microcomputers, particularly regarding video games. Various types of computer-related activity were not related to socioeconomic class of the parents or to academic grades except for use of home microcomputers, which was mildly positively related to socioeconomic class (r = .124, p < .001). Nearly half the activity in the arcades was strictly solitary. None of the arcade video games allowed for cooperative play. Most allowed only for sequential competition (86%) or simultaneous competition (7%); as many as 7% did not provide a display of the scores for a second player.     

Pupil diameter measurement errors as a function of gaze direction in corneal reflection eyetrackers

Pupil dilation is a useful, noninvasive technique for measuring the change in cognitive load. Since it is implicit and nonverbal, it is particularly useful with preverbal or nonverbal participants. In cognitive psychology, pupil dilation is most often measured by corneal reflection eye-tracking devices. The present study investigates the effect of gaze position on pupil size estimation by three common eye-tracking systems. The task consisted of a simple object pursuit situation, as a sphere rotated around the display screen. Systematic errors of pupil size estimation were found with all three systems. Implications for task-elicited pupillometry, especially for gaze-contingent studies such as object tracking or reading, are discussed.     

When bystanders become bothersome: The negative consequences of bystander conflict and the moderating role of resilience

Bystander conflict is a situation in which employees are hindered in their work by parties not involved in the primary process. Public service employees and emergency care workers, such as ambulance employees and firefighters, often encounter this kind of conflict with potentially far-reaching detrimental effects for public or patient safety. Unfortunately, until now, bystander conflict has hardly received scientific attention. In this paper, we will present the results of an experiment (Study 1) and a simulation study (Study 2). Taken together, the results indicate that bystander conflict is negatively related to the affective, behavioural, and cognitive outcomes of individuals. Higher levels of bystander conflict were associated with more negative and less positive feelings (Studies 1, 2), unfavourable bystander appraisals (Studies 1, 2), and lower levels of performance (Study 2). Additionally, Study 2 revealed that bystander conflict was negatively and indirectly related to positive affect and performance through cognitive capacity. We investigated the moderating role of resilience, in order to provide insight into potential factors alleviating these negative associations. In both studies, resilience alleviated the negative associations of bystander conflict. Overall, the results of the two studies provide a first step towards a theory on bystander conflict.     

Reaction times in the study of strategies in sentence-picture verification: A reconsideration

Investigations of cognitive strategies based on chronometric data may appear to contradict findings from verbal-report-based approaches. These inconsistencies may be due to misuse of RTs to infer subjects' behaviour. To test this hypothesis, 15 subjects were successively required to adopt 4 different strategies in a sentence-picture verification task. Trend analyses provide evidence that (1) highly dissimilar strategies can nevertheless yield similar mean RT curves as well as similar individual subjects' RT curves; (2) subjects using similar strategies can produce individual RT curves presenting vastly different features due partly to random variation and partly to idiosyncrasies. These findings suggest that RTs are an unreliable behavioural indicator for inferring individual or group strategies on certain experimental tasks and should be analysed in conjunction with other sources of information. An approach consisting of using RTs to test hypotheses based on subjects' verbal reports is described along with the appropriate controls. Results show that this approach provides an improved account for observed RTs.     

Meeting Deadlines in Work Groups: Implicit and Explicit Mechanisms

Nous nous sommes demandés, dans cette étude, si les groupes étaient mieux à même de respecter les délais quand leurs membres partageaient les mêmes cognitions temporelles, c'est-à-dire quand ils s'accordaient sur les dimensions temporelles de leur tâche. Dans une étude longitudinale portant sur 31 groupes, nous avons étudié l'effet des cognitions temporelles partagées sur le respect d'un délai et exploré deux antécédents des cognitions temporelles partagées: la cohérence des rythmes des membres du groupe et l'échange des rappels concernant le temps. Nos résultats montrent que ces deux facteurs ont un impact sur les cognitions temporelles partagées et cela à différentes étapes du travail collectif. De plus, il est apparu que les cognitions temporelles partagées pouvaient aussi bien faciliter que contrecarrer le respect des délais: cela dépend des rythmes des membres du groupe.
In this study, we examined whether groups were better able to meet deadlines when group members had shared temporal cognitions, that is, when they agreed on the temporal aspects of their task. In a longitudinal study involving 31 groups, we studied the effect of shared temporal cognitions on meeting a deadline and explored two antecedents of shared temporal cognitions: the similarity in group members' pacing styles and the exchange of temporal reminders. Our findings suggest that both antecedents are relevant to shared temporal cognitions, be it at different stages of group collaboration. Furthermore, we found that shared temporal cognitions may either facilitate or impede meeting a deadline, depending on the content of group members' pacing styles.     

Imagining Membership: The Conception of Europe in the Political Thought of T. G. Masaryk and Václav Havel

A decade after the fall of Communism in Europe, the Czech Republic'smembership in the European Union is still a matter of a relatively shortwaiting period of 4 years. Not so the imagination of this membership andthe creation of a political concept created to promote this goal: thespecific Central European policy initiated by Thomas G. Masaryk andrevitalized by Václav Havel. Despite the deep differences in thepolitical thought and philosophical orientations of both Presidents, notto mention the historic rupture of 41 years of Totalitarianism, theirperceptions of Europe as an Imagined Community are identical.
