Sensitivity to differences between enjoyment and non‐enjoyment smiles in children with autism spectrum disorder

The sensitivity of male children (5–15 years) with and without autism spectrum disorder (ASD) to the affective state of others was tested using an emotion recognition task. Only children without ASD could reliably differentiate between enjoyment and non‐enjoyment smiles. Results are considered in terms of the social impairments of children with ASD.     

The Influence of Early Efficacy Beliefs on Teams' Reactions to Failing to Reach Performance Goals

Although a considerable amount of theoretical and empirical attention has been devoted to understanding individuals' responses to goal–performance discrepancies (GPDs), little attention has been devoted to examining how teams respond to GPDs. The present research sought to examine how teams responded to negative GPDs. We predicted that failing to reach higher goals would be perceived as less negative than failing to reach lower goals, and we examined the moderating influence of setting higher versus lower goals on how teams responded to performance that fell short of those goals. We also examined the role that efficacy beliefs that were formed early in those teams played in further explaining these effects. Results from 94 teams who all failed to reach self‐set goals revealed that teams that failed to reach higher goals downwardly revised their goals less than teams that failed to reach lower goals. Early efficacy beliefs further explained these effects. High efficacy beliefs lessened the negative effects of failing to reach lower goals on subsequent goals. High efficacy beliefs also lessened the negative effects of failing to reach higher goals while low efficacy beliefs strengthened the negative effects of failing to reach higher goals. The implications of these findings for theory, research, and practice are discussed.     

Children as Research Collaborators: Issues and Reflections from a Mobility Study in Sub-Saharan Africa

This paper reflects on issues raised by work with children in an ongoing child mobility study in three sub-Saharan African countries: Ghana, Malawi and South Africa. There are now 70 school pupils of varying ages involved in the project, but the paper is particularly concerned with the participation of those children 14 years and under. We examine the significant ethical issues associated with working with younger child researchers, and linked questions concerning the spaces open to them in African contexts where local cultural constructions of childhood and associated economic imperatives (which commonly drive family and household endeavour) help shape the attitudes of adults to children’s rights and responsibilities and inter-generational power relations.     

Temperamental attention and activity, classroom emotional support, and academic achievement in third grade

The purpose of this study is to examine the interplay of children's temperamental attention and activity (assessed when children were 4-and-a-half years old) and classroom emotional support as they relate to children's academic achievement in third grade. Particular focus is placed on the moderating role of classroom emotional support on the relationship between temperament (attention and activity level) and academic achievement. Regression analyses indicated that children's attention and activity level were associated with children's third grade reading and mathematics achievement, and classroom emotional support was associated with children's third grade reading and mathematics achievement. In addition, classroom emotional support moderated the relation between children's attention and reading and mathematics achievement, such that attention mattered most for reading and mathematics achievement for children in classrooms with lower emotional support. Findings point to the importance of understanding how children's temperament and classroom emotional support may work together to promote or inhibit children's academic achievement.     

Religion,Evolution, and Mental Health: Attachment Theory and ETAS Theory

This article reviews the historical origins of Attachment Theory and Evolutionary Threat Assessment Systems Theory (ETAS Theory), their evolutionary basis and their application in research on religion and mental health. Attachment Theory has been most commonly applied to religion and mental health in research on God as an attachment figure, which has shown that secure attachment to God is positively associated with psychological well-being. Its broader application to religion and mental health is comprehensively discussed by Kirkpatrick (2005). ETAS Theory explains why certain religious beliefs—including beliefs about God and life-after-death—should have an adverse association, an advantageous association, or no association at all with mental health. Moreover, it makes specific predictions to this effect, which have been confirmed, in part. The authors advocate the application of ETAS Theory in research on religion and mental health because it explains how religious and other beliefs related to the dangerousness of the world can directly affect psychiatric symptoms through their affects on specific brain structures.     

Ambiguity Advantage Revisited: Two Meanings are Better than One When Accessing Chinese Nouns

This paper revisits the effect of lexical ambiguity in word recognition, which has been controversial as previous research reported advantage, disadvantage, and null effects. We discuss factors that were not consistently treated in previous research (e.g., the level of lexical ambiguity investigated, parts of speech of the experimental stimuli, and the choice of non-words) and report on a lexical decision experiment with Chinese nouns in which ambiguous nouns with homonymic and/or metaphorical meanings were contrasted with unambiguous nouns. An ambiguity advantage effect was obtained—Chinese nouns with multiple meanings were recognized faster than those with only one meaning. The results suggested that both homonymic and metaphorical meanings are psychologically salient semantic levels actively represented in the mental lexicon. The results supported a probability-based model of random lexical access with multiple meanings represented by separate semantic nodes. We further discuss these results in terms of lexical semantic representation and how different experimental paradigms result in different ambiguity effects in lexical access.     

Executive dysfunction in a survival environment

Victims often respond to survival incidents with maladaptive behaviours that suggest impairment in executive function. To examine this hypothesis the authors tested sub‐components of executive function during an intensive military survival exercise. Compared to a control group the survival course participants showed significant impairment in the incongruent condition of the Stroop task; the mean repetition gap and adjacent letter pair components of the random letter generation task; and the planning and action components of the Tower of London task. No impairment was found in dual‐task performance nor in verbal fluency. The pattern of the data suggests that the maladaptive behaviour frequently observed in survival incidents may be explained by dysfunction in the supervisory system‐contention scheduler interface.

Congruency reversals in an accessory signal Simon task with auditory and visual stimuli

In visual two-choice reaction-time tasks, a Simon-like effect occurs when a peripheral accessory signal is presented shortly before or together with the response signal. However, the effect reverses when the peripheral signal appears shortly after the response signal. This pattern also occurs when the peripheral signal appears relative to a go (nogo) signal, with the relevant signal presented well in advance. The reversal has been explained as the inhibition of exogenous response-code activation as soon as an action plan has been developed. In three experiments we investigated whether the inhibition also occurred with auditory and crossmodal stimuli. A Simon effect appeared in all experiments, but the reversal only occurred when peripheral and relevant response signals were auditory, and not when the relevant and irrelevant signals were in a different modality. We suggest that planned actions are protected against exogenous interference by a modality-specific inhibitory process, determined by the relevancy of the modality of the peripheral accessory signal.
