Intentional and Non-Intentional Assessments of Emotion Experiences: Comparisons of Old and New Measures

In two studies, we compared intentional and non-intentional measures of emotional well-being in terms of reliability and validity. In the first study, we expanded on the findings of ?im?ek (2011 ?im?ek, Ö. F. (2011). An Intentional Model of Emotional Well-Being: The Development and Initial Validation of a Measure of Subjective Well-Being. Journal of Happiness Studies, 12, 421–442. [Google Scholar]) by showing that an intentional measure of emotional well-being, namely the Emotional Well-Being Scale, accounted for unique variance in both negative and positive mental health indicators above and beyond the variance accounted for by Larsen and Diener's Scales (1992), which measures all dimensions of affect circumplex. The correlated traits-correlated uniqueness model results showed that the original-intentional version of the Emotional Well-Being Scale explained more variance in the measurement model than the non-intentional version. The second study showed that the results were similar for the intentional vs. non-intentional versions of the Positive and Negative Affect Schedules (Watson, Clark &; Tellegen, 1988 Watson, D., Clark, L. A., &; Tellegen, A. (1988). Development and validation of brief measures of positive and negative affect: The PANAS scales. Journal of Personality and Social Psychology, 54, 1063–1070. [Google Scholar]). The intentional version of the Positive and Negative Affect Schedules accounted for more variance in the criteria than the non-intentional version.     

Professional and non-professional drivers’ stress reactions and risky driving

The aim of the present study was to investigate stress reactions, speeding, number of penalties and accident involvement among different driver groups (taxi drivers, minibus drivers, heavy vehicle drivers, and non-professional drivers). A total number of 234 male drivers participated in the study. The participants were asked to complete the Driver Stress Inventory (DSI) together with a demographic information form. Five dimensions of the DSI were measured; aggression, dislike of driving, hazard monitoring, fatigue proneness, and thrill-seeking. After controlling the effects of age and annual mileage, the results of the ANCOVAs revealed differences between different driver groups in terms of both risky driving behaviours and stress reactions in traffic. Regression analyses indicated that aggression, dislike of driving, and hazard monitoring dimensions of the DSI were related to accident involvement after controlling for the effects of age, annual mileage and driver group. Dislike of driving and thrill-seeking dimensions of the DSI were related to speeding on in-city roads.     

Higher-order Traits and Happiness in the Workplace: The Importance of Occupational Project Scale for the Evaluation of Characteristic Adaptations

This study attempts to explain the relationship between job satisfaction and the Big Two, Stability and Plasticity, which are the higher-order traits of Big Five. Occupational Project, a narrative construct, was considered a mediator variable in this relationship. Occupational Project consists of affective and cognitive evaluations of an individual's work life as a project in terms of the completed (past), the ongoing (present) and the prospective (future) parts. The survey method was applied to a sample of 253 participants. The results supported the proposed model, in which Occupational Project mediated the relationship between the Big Two and both job satisfaction and affect in workplace. Discussion is focused on applying Occupational Project as a practical tool for management. Consideration of an employee's Occupational Project could provide management with a means to question, understand, intervene with and redefine the narrative quality of his/her occupational project that influences job satisfaction.     

The Mediating Role of General Self-Efficacy in the Relationship Between the Big Five Personality Traits and Perceived Stress: A Weekly Assessment Study

A cross-sectional study design may not be a reliable procedure for indicating the effects of stable individual structures on transient conditions in stress situations. In order to address this gap, we aimed to explore the role of the direct and indirect effects of the big five personality traits with the mediating effect of self-efficacy on perceived stress using a weekly diary method. The sample comprised 79 full-time workers who filled in a questionnaire that included the Big Five Inventory and General Self-Efficacy Scale at the initial administration and the Perceived Stress Scale over 12 weeks. Data were analysed using hierarchical linear modelling to examine the relationship between the big five personality traits and weekly perceived stress and the mediating role of general self-efficacy in this relationship. The results indicated that neuroticism and extraversion were significantly associated with general self-efficacy and perceived stress. The results further indicated that general self-efficacy fully mediated the relationship between extraversion and perceived stress. General self-efficacy partially mediated the relationship between neuroticism and perceived stress. Our findings highlight the importance of personality and self-efficacy for predicting perceived stress. Implications for future research and practice are discussed.     

Who Did What to Whom? Children Track Story Referents First in Gesture

Children achieve increasingly complex language milestones initially in gesture or in gesture+speech combinations before they do so in speech, from first words to first sentences. In this study, we ask whether gesture continues to be part of the language-learning process as children begin to develop more complex language skills, namely narratives. A key aspect of narrative development is tracking story referents, specifying who did what to whom. Adults track referents primarily in speech by introducing a story character with a noun phrase and then following the same referent with a pronoun—a strategy that presents challenges for young children. We ask whether young children can track story referents initially in communications that combine gesture and speech by using character viewpoint in gesture to introduce new story characters, before they are able to do so exclusively in speech using nouns followed by pronouns. Our analysis of 4- to 6-year-old children showed that children introduced new characters in gesture+speech combinations with character viewpoint gestures at an earlier age than conveying the same referents exclusively in speech with the use of nominal phrases followed by pronouns. Results show that children rely on viewpoint in gesture to convey who did what to whom as they take their first steps into narratives.     

Measurement Invariance of Personal Well-Being Index (PWI-8) Across 26 Countries

This report examines the measurement invariance of the Personal Well-being Index with 8 items (PWI-8). University students (N = 5731) from 26 countries completed the measure either through paper and pencil or electronic mode. We examined uni-dimensional structure of PWI and performed a Multi-group CFA to assess the measurement invariance across the 26 countries, using conventional approach and the alignment procedure. The findings provide evidence of configural and partial metric invariance, as well as partial scalar invariance across samples. The findings suggest that PWI-8 can be used to examine correlates of life satisfaction across all included countries, however it is impossible to compare raw scores across countries.     

Cultural innovation and transmission of tool use in wild chimpanzees: evidence from field experiments

Chimpanzees (Pan troglodytes) are the most proficient and versatile users of tools in the wild. How such skills become integrated into the behavioural repertoire of wild chimpanzee communities is investigated here by drawing together evidence from three complementary approaches in a group of oil-palm nut- (Elaeis guineensis) cracking chimpanzees at Bossou, Guinea. First, extensive surveys of communities adjacent to Bossou have shown that population-specific details of tool use, such as the selection of species of nuts as targets for cracking, cannot be explained purely on the basis of ecological differences. Second, a 16-year longitudinal record tracing the development of nut-cracking in individual chimpanzees has highlighted the importance of a critical period for learning (3–5 years of age), while the similar learning contexts experienced by siblings have been found to result in near-perfect (13 out of 14 dyads) inter-sibling correspondence in laterality. Third, novel data from field experiments involving the introduction of unfamiliar species of nuts to the Bossou group illuminates key aspects of both cultural innovation and transmission. We show that responses of individuals toward the novel items differ markedly with age, with juveniles being the most likely to explore. Furthermore, subjects are highly specific in their selection of conspecifics as models for observation, attending to the nut-cracking activities of individuals in the same age group or older, but not younger than themselves. Together with the phenomenon of inter-community migration, these results demonstrate a mechanism for the emergence of culture in wild chimpanzees.     

Latent constructs model explaining the attachment-linked variation in autobiographical remembering

In the current study, we proposed a latent constructs model to characterise the qualitative aspects of autobiographical remembering and investigated the structural relations in the model that may vary across individuals. Primarily, we focused on the memories of romantic relationships and argued that attachment anxiety and avoidance would be reflected in the ways that individuals encode, rehearse, or remember autobiographical memories in close relationships. Participants reported two positive and two negative relationship-specific memories and rated the characteristics for each memory. As predicted, the basic memory model yielded appropriate fit, indicating that event characteristics (EC) predicted the frequency of rehearsal (RC) and phenomenology at retrieval (PC). When attachment variables were integrated, the model showed that rehearsal mediated the link between anxiety and PC, especially for negative memories. On the other hand, for avoidance EC was the key factor mediating the link between avoidance and RC, as well as PC. Findings were discussed with respect to autobiographical memory functions emphasising a systematically, integrated framework.
