Concurrent task performance enhances low-level visuomotor learning

Visuomotor association learning involves learning to make a motor response to an arbitrary visual stimulus. This learning is essential for visual search and discrimination performance and is reliant upon a well-defined neural circuit in the brain that includes the prefrontal cortex and the hippocampal formation. In the present study, we investigated the possible role of attentional processes during such learning using dual-task interference. A motor, verbal, or perceptual concurrent task was performed during the learning/training block of a simple visual discrimination task. Contrary to expectation, the dual-task groups showed improved learning and learning-dependent performance compared with untrained control and non-dual-task trained groups. A second experiment revealed that this effect did not appear to be due to increased arousal level; the inclusion of alerting tones during learning did not result in facilitation. These findings suggest that the engagement of attention, but not arousal, during the acquisition of a visuomotor association can facilitate this learning and its expression.     

The Role of Beliefs in Mother-Adolescent Conflict: An Application of the Theory of Planned Behavior

This mixed method study applies components of the theory of planned behavior (Ajzen and Fishbein 1980) to mother-adolescent conflict. We examine if three kinds of beliefs—behavioral, control, and normative—predict patterns of family conflict. Forty mother-adolescent dyads completed an open-ended interview, self-report measures of conflict, and an observational measure of family interaction. Hierarchical multiple regressions revealed that mothers’ and adolescents’ beliefs about the costs and benefits of conflict significantly predicted how they interacted and perceived conflict within dyads. Sex differences and differences between mothers and adolescents were identified. This work contributes to our understanding of the role of both general and specific beliefs in family conflict.     

Familial patterns and the origins of individual differences in synaesthesia

The term synaesthesia has been applied to a range of different sensory-perceptual and cognitive experiences, yet how these experiences are related to each other is not well understood. Not only are there disparate types of synaesthesia, but even within types there are vast individual differences in the way that stimuli induce synaesthesia and in the subjective synaesthetic experience. An investigation of the inheritance patterns of different types of synaesthesia is likely to elucidate whether a single underlying mechanism can explain all types. This study is the first to systematically survey all types of synaesthesia within a familial framework. We recruited 53 synaesthetes and 42% of these probands reported a first-degree relative with synaesthesia. We then directly contacted as many first-degree relatives as possible and collected complete data on synaesthetic status for all family members for 17 families. We found that different types of synaesthesia can occur within the same family and that the qualitative nature of the experience can differ between family members. Our findings strongly indicate that various types of synaesthesia are fundamentally related at the genetic level, but that the explicit associations and the individual differences between synaesthetes are influenced by other factors. Synaesthesia thus provides a good model to explore the interplay of all these factors in the development of cognitive traits in general.     

Political Violence and Psychological Well-Being: The Role of Social Identity

A significant body of research points to the central role of identity in creating and maintaining conflict. However, less research has focused on the protective role of social identity in such situations. Using a survey sample of 3,000 participants, 2,000 of whom were resident in a conflict-affected region (Northern Ireland) and 1,000 in a region more distally affected (the Border counties of the Republic of Ireland) the potential moderating and mediating impact of national identification on the relationship between direct and indirect experience of political violence and psychological well-being is examined. Findings indicate that national identification mediates the impact of direct political violence on well-being in Northern Ireland. This relationship is strongest where preferred nationality is relevant to the social division underlying the conflict. Those more distally affected, resident in the Republic of Ireland, did not evidence this pattern of relationships. Discussion of results focuses on the potential positive and negative implications of these findings for personal and societal well-being, respectively.     

Career transitions and their causes: A country‐comparative perspective

This empirical paper investigates how individuals conceptualize causes of career transitions, focusing on the three European countries of Austria, Serbia, and Spain in comparison to the USA and China. Collectively, these countries represent four separate cultural regions according to Schwartz. Semi‐structured interviews were conducted with members of three occupational groups: business people, nurses, and blue‐collar workers. Analysis of the data generates greater insight about the existence of both region‐specific patterns as well as potentially universalistic tendencies regarding perceived causes of career transitions. Perceptions of internal (to the person) drivers of career transitions as activating forces are evident in all five countries. The overall results support contemporary notions of occupational careers that are highly individualized, a characterization strongly emphasized in the current career literature. In the European culture clusters, causes of career transitions are attributed internally and externally. China, representing the Confucian cultural region, stresses external causes for career transitions. By contrast, in the USA only internal attributions of causes are reported.     

Employability during unemployment: Adaptability, career identity and human and social capital

Recently, Fugate et al. [Fugate, M., Kinicki, A. J., & Ashforth, B. E. (2004). Employability: A psycho-social construct, its dimensions, and applications. Journal of Vocational Behavior, 65(1), 14] defined employability as a psycho-social construct comprised of three dimensions: (i) adaptability; (ii) career identity; and (iii) human and social capital. The aim of the current paper was to empirically test Fugate et al.’s model in a sample of 416 unemployed Australians (n = 126 for longitudinal sample). Specifically, this research explored employability in relation to three aspects of unemployment: (1) self-esteem during unemployment; (2) job search during unemployment; and (3) re-employment (at a 6-month follow-up). Overall, the results of this longitudinal study provide broad support for the psycho-social construct of employability and demonstrate its applicability to the unemployment context.     

Avatar-based therapy within prison settings: pilot evaluation

The paper presents an introduction of a newly developed, avatar-based virtual reality therapy, as an addition to the therapeutic programme, within a therapeutic community prison in the UK. The participants had six group sessions facilitated by a counsellor. The aim of the project was to investigate whether this approach would improve mental health outcomes for the prisoners, interpersonal relationships within the prison and facilitate the achievement of personal goals for the prisoners. The sample size (n?=?4) was insufficient to make firm conclusions about the mental health outcomes. However, the qualitative analysis showed a strong engagement with the programme in addressing personal issues, the development of insight and empathy, and improvements in relationships within the participants and with the counsellor. Further research with a larger sample is needed to establish efficacy of this type of therapy with the prison population.     

Visual feature vs. conjunction searches as a robust manipulation of perceptual load

It has previously been suggested that Lavie’s Perceptual Load Theory can be assessed using feature vs. conjunction search tasks. In this study we manipulated load using a novel paradigm which retains the key features of both classic Load Theory and Feature Integration Theory paradigms. This new paradigm has the advantage of an inbuilt manipulation check which is necessary for future research to translate Load Theory to applied contexts. Across five experiments, we demonstrate the robust nature of this paradigm, which functions with extended display times, large, complex stimuli and when conditions are intermixed on a trial-by-trial basis. We also rule out dilution as a possible cause of these results. The results of all five experiments provide evidence that the feature vs. conjunction search dichotomy is an effective means of imposing low and high perceptual load while controlling for working memory load.     

The Elephant in the Road: Auditory Perceptual Load Affects Driver Perception and Awareness

Summary Perceptual load theory research has shown that the level of perceptual load in a task affects processing of additional information. Less certain are the cross‐modal effects of perceptual load—does load in one modality affect processing in another? The current study assessed the effect of auditory perceptual load on visual attention in a driving simulator task. While driving, participants listened to traffic updates on the radio, which imposed either low or high perceptual load. Awareness for an unexpected animal as well as less novel objects (such as billboards and other vehicles) was markedly reduced under high load. Driver behaviour was also significantly affected, with impaired lateral control, longer reaction times to hazards and more collisions under high load. This study has important implications for load theory and also more general implications for road safety, as it suggests that auditory load may be an important, often overlooked factor in driver attention.Copyright © 2017 John Wiley & Sons, Ltd.
