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.     

Orthographic error monitoring in old age: lexical and sublexical availability during perception and production

Previous research suggests that older adults suffer declines in producing accurate spellings but retain the ability to accurately detect misspellings. The preservation of perception in the face of impaired production has been used to support a model of aging in which age impairs access to linguistic representations under specific circumstances, while representations themselves remain intact. The current research tests two predictions of this Transmission Deficit Hypothesis (TDH): first, that the differential effect of age on perception and production occurs when tasks are equated on response requirements and underlying representations, and second, that both word and spelling frequency interact to determine the effect of age on performance. Results of two error monitoring tasks supported the predictions of the TDH, demonstrating age-related production impairments that interacted with both word and spelling frequency, but no impairment of older adults' spelling perception, even for low frequency words or spellings.     

Planning in sentence production: Evidence for the phrase as a default planning scope

Controversy remains as to the scope of advanced planning in language production. Smith and Wheeldon (1999) found significantly longer onset latencies when subjects described moving-picture displays by producing sentences beginning with a complex noun phrase than for matched sentences beginning with a simple noun phrase. While these findings are consistent with a phrasal scope of planning, they might also be explained on the basis of: (1) greater retrieval fluency for the second content word in the simple initial noun phrase sentences and (2) visual grouping factors. In Experiments 1 and 2, retrieval fluency for the second content word was equated for the complex and simple initial noun phrase conditions. Experiments 3 and 4 addressed the visual grouping hypothesis by using stationary displays and by comparing onset latencies for the same display for sentence and list productions. Longer onset latencies for the sentences beginning with a complex noun phrase were obtained in all experiments, supporting the phrasal scope of planning hypothesis. The results indicate that in speech, as in other motor production domains, planning occurs beyond the minimal production unit.     

The dimensionality and antecedents of emotional labor strategies

This investigation had two purposes. The first was to determine whether the display of naturally felt emotions is distinct from surface acting and deep acting as a method of displaying organizationally desired emotions. The second purpose was to examine dispositional and situational antecedents of surface acting, deep acting, and the expression of naturally felt emotions. Results supported a three-dimensional structure separating deep acting, surface acting, and the expression of naturally felt emotions. In addition, the dispositional and situational variables exhibited theoretically consistent and distinct patterns of relationships with the three emotional labor strategies. Overall, the results of this study expand the nomological network of surface acting and deep acting and suggest that the expression of naturally felt emotions is a distinct strategy for displaying emotions at work and should be included in research on emotional labor.     

Clarifying Heterogeneity of Daytime and Nighttime Symptoms of Posttraumatic Stress in Combat Veterans With Insomnia

Daytime and nighttime symptoms of posttraumatic stress disorder (PTSD) are common among combat veterans and military service members. However, there is a great deal of heterogeneity in how symptoms are expressed. Clarifying the heterogeneity of daytime and nighttime PTSD symptoms through exploratory clustering may generate hypotheses regarding ways to optimally match evidence-based treatments to PTSD symptom profiles. We used mixture modeling to reveal clusters based on 6 daytime and nighttime symptoms of 154 combat veterans with insomnia and varying levels of PTSD symptoms. Three clusters with increasing symptom severity were identified (n1 = 50, n2 = 70, n3 = 34). These results suggest that, among veterans with insomnia, PTSD symptoms tend to exist on a continuum of severity, rather than as a categorical PTSD diagnosis. Hypotheses regarding possible targeted treatment strategies for veterans within each identified cluster, as well as ways to generalize these methods to other groups within the military, are discussed.     

Play Behavior and Playfulness in Adulthood

Although research has established play behavior and playfulness as important to the well‐being of children and animals, researchers have not typically considered the importance or implications of play in human adults. This is surprising given that play behavior is a topic of high relevance to social psychology. Definitional issues, a lack of a theoretical framework, and a dearth of standardized measures have posed obstacles in the advancement of this interesting research area, which is ripe for investigation. In this review, we summarize the extant literature, identify strengths and weaknesses of this literature, propose definitions to guide future work in this area, identify relevant theories that may be expanded to provide a framework for programmatic research on play in adulthood, and elucidate avenues for future research. Our aim is to encourage the development of this research area within social psychology.
