Developmental Characteristics of Disparate Bimanual Movement Skills in Typically Developing Children

Mastery of many tasks in daily life requires role differentiated bimanual hand use with high spatiotemporal cooperation and minimal interference. The authors investigated developmental changes in the performance of a disparate bimanual movement task requiring sequenced movements. Age groups were attributed to changes in CNS structures critical for bimanual control such as the corpus callosum (CC) and the prefrontal cortex; young children (5–6 years old), older children (7–9 years old), and adolescents (10–16 years old). Results show qualitative changes in spatiotemporal sequencing between the young and older children which typically marks a phase of distinct reduction of growth and myelination of the CC. Results show qualitative changes in spatiotemporal sequencing between the young and older children, which coincides with distinct changes in the growth rate and myelination of the CC. The results further support the hypothesis that CC maturation plays an important role in the development of bimanual skills.     

Mapping language to the world: the role of iconicity in the sign language input

Most research on the mechanisms underlying referential mapping has assumed that learning occurs in ostensive contexts, where label and referent co‐occur, and that form and meaning are linked by arbitrary convention alone. In the present study, we focus on iconicity in language, that is, resemblance relationships between form and meaning, and on non‐ostensive contexts, where label and referent do not co‐occur. We approach the question of language learning from the perspective of the language input. Specifically, we look at child‐directed language (CDL) in British Sign Language (BSL), a language rich in iconicity due to the affordances of the visual modality. We ask whether child‐directed signing exploits iconicity in the language by highlighting the similarity mapping between form and referent. We find that CDL modifications occur more often with iconic signs than with non‐iconic signs. Crucially, for iconic signs, modifications are more frequent in non‐ostensive contexts than in ostensive contexts. Furthermore, we find that pointing dominates in ostensive contexts, and suggest that caregivers adjust the semiotic resources recruited in CDL to context. These findings offer first evidence for a role of iconicity in the language input and suggest that iconicity may be involved in referential mapping and language learning, particularly in non‐ostensive contexts.     

Apparent motion enhances visual rhythm discrimination in infancy

Many studies have demonstrated that infants exhibit robust auditory rhythm discrimination, but research on infants' perception of visual rhythm is limited. In particular, the role of motion in infants' perception of visual rhythm remains unknown, despite the prevalence of motion cues in naturally occurring visual rhythms. In the present study, we examined the role of motion in 7-month-old infants' discrimination of visual rhythms by comparing experimental conditions with apparent motion in the stimuli versus stationary rhythmic stimuli. Infants succeeded at discriminating visual rhythms only when the visual rhythm occurred with an apparent motion component. These results support the view that motion plays a role in infants' perception of visual temporal information, consistent with the manner in which natural rhythms appear in the visual world.     

Dimension-specific attention directs learning and listening on auditory training tasks

The relative contributions of bottom-up versus top-down sensory inputs to auditory learning are not well established. In our experiment, listeners were instructed to perform either a frequency discrimination (FD) task ("FD-train group") or an intensity discrimination (ID) task ("ID-train group") during training on a set of physically identical tones that were impossible to discriminate consistently above chance, allowing us to vary top-down attention whilst keeping bottom-up inputs fixed. A third, control group did not receive any training. Only the FD-train group improved on a FD probe following training, whereas all groups improved on ID following training. However, only the ID-train group also showed changes in performance accuracy as a function of interval with training on the ID task. These findings suggest that top-down, dimension-specific attention can direct auditory learning, even when this learning is not reflected in conventional performance measures of threshold change.     

The wisdom of the crowd playing The Price Is Right

In The Price Is Right game show, players compete to win a prize, by placing bids on its price. We ask whether it is possible to achieve a "wisdom of the crowd" effect, by combining the bids to produce an aggregate price estimate that is superior to the estimates of individual players. Using data from the game show, we show that a wisdom of the crowd effect is possible, especially by using models of the decision-making processes involved in bidding. The key insight is that, because of the competitive nature of the game, what people bid is not necessarily the same as what they know. This means better estimates are formed by aggregating latent knowledge than by aggregating observed bids. We use our results to highlight the usefulness of models of cognition and decision-making in studying the wisdom of the crowd, which are often approached only from non-psychological statistical perspectives.     

Career support for migrants: Transformation or adaptation?

The complex interfaces created by migration not only challenge core beliefs about the purpose of career guidance and counseling but also about the precise nature and level of the support required for migrants. However, the issue has had little academic attention. While traditional theories informing the practice of career guidance and counseling implicitly reflect a commitment to social equality, they were developed in relatively homogenous Western capitalist contexts that were strongly individualized, masculine, secular, action and future focused. As career guidance and counseling services in more individualized countries seek to meet the needs of a growing number of clients from more collectivist cultures, the universal relevance of such models is increasingly open to challenge. This article explores three core challenges posed by migration for the theory and practice of career guidance and counseling. The first relates to the very purpose of these types of services for migrants; the second, to the way in which migration requires a realignment of the relationship of theory with practice; and the third relates to the need to redefine service delivery models for this client group. The extent to which notions of “quality” in services are culturally dependent will also be considered, together with the potential for general service improvements being stimulated by the provision of high quality services for migrants.     

Aggressive reactions to abusive supervision: the role of interactional justice and narcissism

In this study, we explore personality and situational conditions in which negative leadership - specifically, abusive supervision - is associated with aggressive behavior in subordinates. That is, we examine the role that interactional justice and narcissism play in an employee's decision to respond aggressively to an abusive supervisor. We demonstrate that interactional justice mediates the relationship between perceptions of abusive supervision and subsequent employee aggression. In addition, we demonstrate that narcissism interacts with interactional justice perceptions to predict workplace aggression. We find that individuals with high levels of narcissism are the employees who are most likely to respond aggressively when they interpret their leader's behavior as abusive.
