Lateralisation of language and emotion in schizotypal personality: Evidence from dichotic listening

Striking disturbances have been reported in language and emotional prosody processing by patients diagnosed with schizophrenia. In view of this and of research suggesting that schizotypal personality traits can also be expressed sub-clinically, the present study aimed to discover whether similar disturbances would be reflected in cognitive laterality patterns when symptoms of schizotypy are present yet at a non-clinical level. A dichotic listening task was used to examine the sensitivity and speed with which 132 right-handed participants (85 females and 47 males, mean age = 32.44, SD = 12.29) detected both words and emotional prosody, all of whom also completed the Schizotypal Personality Questionnaire. Findings indicated that both high (n = 64) and low (n = 68) schizotypy groups demonstrated the typical right ear advantage for the detection of words and left ear advantage for the detection of emotional prosody. Individuals with higher schizotypal personality scores also demonstrated poorer sensitivity in detecting emotional prosody. These results reveal that within the healthy population, higher levels of schizotypy are not associated with the atypical lateralisation of language and emotion. Nevertheless, the existence of these symptoms does signal the presence of shared characteristics with the clinical sphere, namely poorer emotion recognition performance.     

Predicting counterproductive work behavior from the interaction of personality traits

Much attention has been given to enhancing the prediction of counterproductive work behavior (CWB), with a particular focus on the relationship between the five factor model of personality and CWB. Several scholars have advocated for a more complex view of this relationship, and rather than focusing simply on main effects, to examine the interaction of personality traits in predicting employee behavior. In consideration of the traits most strongly related to CWB, we examined the interaction between: (1) conscientiousness and emotional stability, (2) agreeableness and emotional stability, and (3) conscientiousness and agreeableness on CWB directed at individuals (CWB-I) and the organization (CWB-O). Results from a multi-national sample illustrate the interaction of traits increases the prediction of CWB over and above a single trait approach. The interactions suggest employees perform the least CWB when they are high on both traits (in the respective trait pairings), but low levels on either trait relate to increased CWB, and at levels comparable to individuals low on both traits. We conclude research on personality and CWB would benefit from an interactive approach as it allows for greater prediction of CWB-O and CWB-I, which is important in light of the organizational and interpersonal consequences of employee misbehavior.     

Planification de l’âge du départ à la retraite professionnelle : contribution de l’ouverture aux expériences

The present research examines mechanisms underlying planned retirement age by applying Beehr’Model (1986). The contribution of personality traits was investigated among 300 active employees. Multiple regression analyses, performed at both broad and facet-level, revealed that Openness to experiences and ideas positively contribute to planned retirement age beyond variables of Beehr’Model (i.e., personal, contextual and psychological variables). This study contributes to an in-depth understand of planning retirement mechanisms and insists on the major role of dispositional variables.     

Comparing elite male and female distance runner's experiences of disordered eating through narrative analysis

ObjectivesResearchers have called for additional forms of theorizing and qualitative methodologies to explore disordered eating in athletes. The current study used social constructionism and narrative analysis to compare and contrast the disordered eating experiences of one male and female athlete.DesignNarrative inquiry was combined with an in-depth case study approach to explore the narrative and gendered construction of disordered eating in one elite male (age 19) and female (age 34) distance runner. The personal and cultural narratives drawn upon to construct meanings around the body, food and running and how these framed experiences were of interest.MethodsA structural and performative narrative analysis was conducted on four in-depth interviews (i.e., both runners participated in two separate interviews).ResultsBoth runners drew upon a performance narrative to construct running experiences and self-identities as elite athletes. When elite athletic identity became threatened by moments of perceived failure (e.g., poor performance, injury), disordered eating thoughts and behaviors emerged for both runners. Gendered narratives around the body, food and running further differentiated specific meanings and the emotional impact of these experiences for each male and female athlete.ConclusionsThis study extends quantitative and qualitative explorations of disordered eating in distance runners by highlighting additional understandings of the complex social, cultural and gendered construction of these experiences.     

Written Exposure Therapy for Suicide in a Psychiatric Inpatient Unit: A Case Series

Patients with posttraumatic stress disorder (PTSD) are at an elevated risk of suicide. For patients hospitalized for suicide risk, psychosocial treatment and stabilization are routinely offered; however, the availability of evidence-based, manualized therapeutic interventions for PTSD is sparse. Typically, the short duration of hospitalization makes it difficult to accommodate evidence-based, trauma-focused treatments. This article presents the clinical course of four active-duty service members with PTSD who were hospitalized in a psychiatric inpatient unit for acute suicide risk and treated with Written Exposure Therapy for Suicide (WET-S). WET-S is a brief, five-session therapy based upon Written Exposure Therapy and augmented with Crisis Response Planning for Suicide Prevention. Both posttraumatic stress symptoms and suicidal ideation were reduced from pre- to posttreatment for three of the four patients treated. WET-S shows promise as a manualized therapeutic intervention that can be delivered on an inpatient psychiatric unit.     

Personality predicts innovation and social learning in children: Implications for cultural evolution

Innovation and social learning are the pillars of cultural evolution, allowing cultural behaviours to cumulatively advance over generations. Yet, little is known about individual differences in the use of social and asocial information. We examined whether personality influenced 7-11-year-old children's (N = 282) propensity to elect to observe others first or independently generate solutions to novel problems. Conscientiousness was associated with electing for no demonstrations, while agreeableness was associated with opting for demonstrations. For children receiving demonstrations, openness to experience consistently predicted deviation from observed methods. Children who opted for no demonstrations were also more likely than those opting for demonstrations to exhibit tool manufacture on an innovation challenge and displayed higher creativity, as measured by an alternate uses task. These results highlight how new cultural traditions emerge, establish and advance by identifying which individuals generate new cultural variants in populations and which are influential in the diffusion of these variants, and help reduce the apparent tension within the ‘ratchet’ of cumulative culture.     

自闭症谱系障碍个体的社会动机缺陷

自闭症谱系障碍(ASD)是一种源于儿童期的神经发育障碍, 社会交往障碍是其核心特征, 与社会动机缺陷密切相关。社会动机是引导个体社会行为的强大动力, 主要表现为社会定向、社会奖赏和社会维持。现有研究表明, ASD个体的社会动机发展存在缺陷, 他们对社会刺激的注意偏向减少, 不能主动寻求和体会社会互动带来的快乐, 且缺乏维持社会关系的行为策略等。然而, 相关研究结果受到个体特征、环境和实验设计等因素的影响。研究者未来应综合考虑这些影响因素, 加强对ASD个体社会动机理论的整合研究, 以便全面系统地了解ASD个体的社会动机缺陷。
