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.     

The role of goal-directed behavior in intention attribution in children

In this study, we addressed the question of the nature of the information needed by 13-month-old infants to understand another agent's intentions. In two experiments, an experimenter was either unable or unwilling to give a toy to an infant. Importantly, an implement (a gutter in which the toy could roll down toward the infant) was used to make the experimenter's behavior as similar as possible in the two conditions. When the experimenter remained still in both conditions, infants did not behave differently according to the experimenter's intentions, suggesting that they did not infer them. By contrast, in a second experiment, where the experimenter performed an action directed toward the gutter in both conditions, the infants looked away from the experimental setting more often and longer in the unwilling condition than in the unable condition. They also looked more toward the experimenter in the unable condition than in the unwilling condition. Therefore, we conclude that an agent's intentional attitude can already be inferred by a 13-month-old provided that this intention is concretely shown through a goal-directed action.     

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.     

Peer interaction in child care centres at 15 and 23 months: stability and links with children's socio-emotional adjustment

In this longitudinal study, 70 children were observed during 90 min of free play in their child care centres at 15 and 23 months of age. The children (39 boys and 31 girls) attended 51 different care groups in 39 centres. The occurrence and stability of peer interactions in the second year of life and their relations to children's socio-emotional adjustment were examined. The frequency of children's negative initiatives towards peers showed significant inter-individual stability from 15 to 23 months and predicted child aggressive/disruptive behaviour at 23 months as rated by professional caregivers in child care. Involvement in positive interactions with peers, and particularly positive responses to peer behaviours at 15 months, predicted well-being in child care at 23 months as rated by professional caregivers. The frequency of negative initiatives towards peers significantly increased and the frequency of positive responses to peer behaviours significantly decreased from 15 to 23 months.     

Numbers and space: a computational model of the SNARC effect

The SNARC (spatial numerical associations of response codes) effect reflects the tendency to respond faster with the left hand to relatively small numbers and with the right hand to relatively large numbers (S. Dehaene, S. Bossini, & P. Giraux, 1993). Using computational modeling, the present article aims to provide a framework for conceptualizing the SNARC effect. In line with models of spatial stimulus-response congruency, the authors modeled the SNARC effect as the result of parallel activation of preexisting links between magnitude and spatial representation and short-term links created on the basis of task instructions. This basic dual-route model simulated all characteristics associated with the SNARC effect. In addition, 2 experiments tested and confirmed new predictions derived from the model.     

Shared spatial representations for numbers and space: the reversal of the SNARC and the Simon effects

In 4 experiments, the authors investigated the reversal of spatial congruency effects when participants concurrently practiced incompatible mapping rules (J. G. Marble & R. W. Proctor, 2000). The authors observed an effect of an explicit spatially incompatible mapping rule on the way numerical information was associated with spatial responses. The authors also observed an effect of an incompatible numerical mapping rule (if smaller than 5, press right; if larger than 5, press left) on the Simon effect. This effect was observed only when both tasks used the same effectors. The results point to a shared spatial representation for explicit spatial information (locations) and implicit spatial information (numbers).     

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.
