Emotional intelligence and personal growth initiative effects on subjective happiness among university students

This study examined emotional intelligence and personal growth initiative influences on the level of subjective happiness among university students in Ghana. Two hundred and sixty undergraduate students were participants (female = 69.8%; mean age = 21.72 years, SD = 3.61 years). They responded to measures of emotional intelligence, personal growth initiative, and subjective happiness. After controlling for their demographic characteristics, and following hierarchical regression analysis, results indicate emotional intelligence and intentional behaviour domain of personal growth to predict students’ level of subjective happiness. These findings suggest that students’ ability to manage and utilise their emotions, as well as their personal growth initiative contribute significantly to their level of happiness.     

TreeBUGS: An R package for hierarchical multinomial-processing-tree modeling

Multinomial processing tree (MPT) models are a class of measurement models that account for categorical data by assuming a finite number of underlying cognitive processes. Traditionally, data are aggregated across participants and analyzed under the assumption of independently and identically distributed observations. Hierarchical Bayesian extensions of MPT models explicitly account for participant heterogeneity by assuming that the individual parameters follow a continuous hierarchical distribution. We provide an accessible introduction to hierarchical MPT modeling and present the user-friendly and comprehensive R package TreeBUGS, which implements the two most important hierarchical MPT approaches for participant heterogeneity—the beta-MPT approach (Smith & Batchelder, Journal of Mathematical Psychology 54:167-183, 2010) and the latent-trait MPT approach (Klauer, Psychometrika 75:70-98, 2010). TreeBUGS reads standard MPT model files and obtains Markov-chain Monte Carlo samples that approximate the posterior distribution. The functionality and output are tailored to the specific needs of MPT modelers and provide tests for the homogeneity of items and participants, individual and group parameter estimates, fit statistics, and within- and between-subjects comparisons, as well as goodness-of-fit and summary plots. We also propose and implement novel statistical extensions to include continuous and discrete predictors (as either fixed or random effects) in the latent-trait MPT model.     

Automated respiratory sinus arrhythmia measurement: Demonstration using executive function assessment

Respiratory sinus arrhythmia (RSA) is a quantitative metric that reflects autonomic nervous system regulation and provides a physiological marker of attentional engagement that supports cognitive and affective regulatory processes. RSA can be added to executive function (EF) assessments with minimal participant burden because of the commercial availability of lightweight, wearable electrocardiogram (ECG) sensors. However, the inclusion of RSA data in large data collection efforts has been hindered by the time-intensive processing of RSA. In this study we evaluated the performance of an automated RSA-scoring method in the context of an EF study in preschool-aged children. The absolute differences in RSA across both scoring methods were small (mean RSA differences = –0.02–0.10), with little to no evidence of bias for the automated relative to the hand-scoring approach. Moreover, the relative rank-ordering of RSA across both scoring methods was strong (rs = .96–.99). Reliable changes in RSA from baseline to the EF task were highly similar across both scoring methods (96%–100% absolute agreement; Kappa = .83–1.0). On the basis of these findings, the automated RSA algorithm appears to be a suitable substitute for hand-scoring in the context of EF assessment.     

“There's No Place to Hide”: Exploring the Stressors Encountered by Elite Cricket Captains

This study aimed to enhance understanding of stressors that elite sporting captains face in their role. The autobiographies of 12 international cricket captains were sampled. Stressors relating to the captaincy role were identified, and following thematic analysis, 7 general dimensions of stressors were recognized: multiple roles, team stressors, interactions with players, selection, interactions with other personnel, the media, and extreme situations. It appears that stressors are heightened due to a combination of playing and leadership responsibilities that captains experience. Findings are considered, including how they might be used to inform practitioners and coaches who work with captains.     

Breast Cancer Genetics Knowledge and Testing Intentions among Nigerian Professional Women

Genetic testing services for breast cancer are well established in developed countries compared to African populations that bear a disproportionate burden of breast cancer (BC). The objective of this study is to examine the knowledge of professional Nigerian women about BC genetics and their intentions to utilize genetic testing services when it is made available in Nigeria. In this study, 165 lecturers and 189 bankers were recruited and studied using a validated self-administered questionnaire. The respondents’ mean age was 34.9 years (SD?=?10.9), 6.5% had family history of BC, and 84.7% had limited knowledge of breast cancer genetics. The proportion of women with genetic testing intentions for breast cancer was 87.3%. Health care access (OR?=?2.35, 95% CI, 1.07–5.13), religion (OR?=?3.51, 95% CI, 1.03–11.92), and perceived personal risk if a close relative had breast cancer (OR?=?2.31, 95% CI, 1.05–5.08) independently predicted testing intentions. The genetic testing intentions for BC were high despite limited knowledge about breast cancer genetics. Promotion of BC genetics education as well as efforts to make BC genetic testing services available in Nigeria at reduced cost remains essential.     

Reactionary Deconversion from Mormonism: Polarization of Ideological and Behavioral Religiosity Among Active and Former Mormons

In contrast to a growing body of literature examining the experiences and trends of those who leave their faith tradition—particularly among Christian denominations—relatively little is known about those who specifically disaffiliate from Mormonism, although some evidence suggests that former Mormons may be especially likely to embrace secularity or irreligion rather than other religious beliefs and practices. Pursuant to empirically investigating this reactionary dynamic, the current study compared the relative religiosity and secularity of an online sample of active Mormons (n?=?194) and former Mormons (n?=?109) using the Abbreviated Religiousness Measure (ARM), an updated questionnaire of multidimensional religiosity. Results supported the ARM’s improved psychometrics and its hypothesized three-factor structure with both subsamples. Additionally, multivariate and univariate results indicated that active and former Mormon participants from our sample, significantly polarized in their self-reported level of religious beliefs, rituals, and influence on daily behaviors, with active Mormon reporting high religiosity and former Mormons reporting low religiosity or high secularity. Although these results comport with reactionary deconversion dynamics found in other high cost religions, limits to generalizability are discussed. Reasons for and implications of this reactionary phenomenon are also posited.

Causal Networks or Causal Islands? The Representation of Mechanisms and the Transitivity of Causal Judgment

Knowledge of mechanisms is critical for causal reasoning. We contrasted two possible organizations of causal knowledge—an interconnected causal network, where events are causally connected without any boundaries delineating discrete mechanisms; or a set of disparate mechanisms—causal islands—such that events in different mechanisms are not thought to be related even when they belong to the same causal chain. To distinguish these possibilities, we tested whether people make transitive judgments about causal chains by inferring, given A causes B and B causes C, that A causes C. Specifically, causal chains schematized as one chunk or mechanism in semantic memory (e.g., exercising, becoming thirsty, drinking water) led to transitive causal judgments. On the other hand, chains schematized as multiple chunks (e.g., having sex, becoming pregnant, becoming nauseous) led to intransitive judgments despite strong intermediate links ((Experiments 1–3). Normative accounts of causal intransitivity could not explain these intransitive judgments (Experiments 4 and 5).     

The consequences of suggesting false childhood food events

We combined data across eight published experiments (N = 1369) to examine the formation and consequences of false autobiographical beliefs and memories. Our path models revealed that the formation of false autobiographical belief fully mediated the pathway between suggesting to people that they had experienced a positive or negative food-related event in the past and current preference for that food. Suggestion indirectly affected intention to eat the food via change in autobiographical belief. The development of belief with and without memory produced similar changes in food preferences and behavior intention, indicating that belief in the event drives changes in suggestion-related attitudes. Finally, positive suggestions (e.g., “you loved asparagus the first time you tried it”) yielded stronger effects than negative suggestions (e.g., “you got sick eating egg salad”). These findings show that false autobiographical suggestions lead to the development of autobiographical beliefs, which in turn, have consequences for one's attitudes and behaviors.
