Who benefits from emotional expression? An examination of personality differences among gynaecological cancer patients participating in a randomized controlled emotional disclosure intervention trial

The present study examined the role of neuroticism and extraversion in the effects of written emotional disclosure in patients diagnosed with gynaecological cancer. It was hypothesized that high levels of neuroticism would be associated with an increase in distress after emotional disclosure as mediated by heightened negative affect and avoidance post-disclosure. Conversely, we expected high extraversion to be associated with decreased distress as mediated by heightened positive moods and a decrease in avoidance. Eighty-eight participants were randomly assigned to participate in an expressive writing task versus a control writing task. Distress and avoidance were assessed at baseline and 6 months post-writing. Negative and positive mood were assessed immediately following writing. Multiple regression confirmed that neuroticism but not extraversion moderates the effects of emotional disclosure on distress, however no significant mediating relationships were found.     

Neurobiological and memory models of risky decision making in adolescents versus young adults

Predictions of fuzzy-trace theory and neurobiological approaches are examined regarding risk taking in a classic decision-making task--the framing task--as well as in the context of real-life risk taking. We report the 1st study of framing effects in adolescents versus adults, varying risk and reward, and relate choices to individual differences, sexual behavior, and behavioral intentions. As predicted by fuzzy-trace theory, adolescents modulated risk taking according to risk and reward. Adults showed standard framing, reflecting greater emphasis on gist-based (qualitative) reasoning, but adolescents displayed reverse framing when potential gains for risk taking were high, reflecting greater emphasis on verbatim-based (quantitative) reasoning. Reverse framing signals a different way of thinking compared with standard framing (reverse framing also differs from simply choosing the risky option). Measures of verbatim- and gist-based reasoning about risk, sensation seeking, behavioral activation, and inhibition were used to extract dimensions of risk proneness: Sensation seeking increased and then decreased, whereas inhibition increased from early adolescence to young adulthood, predicted by neurobiological theories. Two additional dimensions, verbatim- and gist-based reasoning about risk, loaded separately and predicted unique variance in risk taking. Importantly, framing responses predicted real-life risk taking. Reasoning was the most consistent predictor of real-life risk taking: (a) Intentions to have sex, sexual behavior, and number of partners decreased when gist-based reasoning was triggered by retrieval cues in questions about perceived risk, whereas (b) intentions to have sex and number of partners increased when verbatim-based reasoning was triggered by different retrieval cues in questions about perceived risk.     

Predictors of Suicide‐Related Hospitalization among U.S. Veterans Receiving Treatment for Comorbid Depression and Substance Dependence

This study examined whether widely accepted suicide risk factors are useful in predicting suicide-related hospitalization, beyond history of a suicide attempt, in high-risk treatment-seeking veterans with depression and substance dependence. Negative mood regulation expectancies were the only significant predictor of hospitalization during 6-months of outpatient treatment. History of a suicide attempt was the only significant predictor of hospitalization during the one-year follow-up period. Results suggest that within high-risk populations, standard suicide risk factors may not identify individuals who will engage in suicidal behaviors resulting in hospitalization. Assessing negative mood regulation expectations may assist in identifying those most at risk.     

A meta-analytic investigation of virtuality and information sharing in teams

We uncover new insights on the role of virtuality on team information sharing. A new two-dimensional conceptualization of information sharing (Mesmer-Magnus & DeChurch, 2009) enabled us to reconcile past inconsistencies in the virtual team literature. Recasting the findings of 94 studies (total number of groups = 5596; total N approximately = 19,702) into this framework reveals three key insights. First, virtuality improves the sharing of unique information, but hinders the openness of information sharing. Second, unique information sharing is more important to the performance of face-to-face teams than is open information sharing, whereas open information sharing is more important to the performance of virtual teams than is unique information sharing. Third, the effects of virtuality on information sharing are more curvilinear than linear – such that low levels of virtuality improve information sharing, but high levels hider it. Implications for research and practice are discussed.     

The importance of contextual variables when judging fairness: An examination of counterfactual thoughts and fairness theory

This research empirically examines the underlying mechanisms of fairness theory (  and ), namely counterfactual thought processes. Study 1 used a policy-capturing design to examine the relative importance of contextual variables in predicting counterfactual thoughts and fairness perceptions. Study 2 utilized a between-subjects design and asked participants to generate their own counterfactuals in response to an unfortunate event. Results of both studies showed that fairness perceptions are influenced by contextual variables (i.e., outcome severity, target knowledge and expertise, sin of commission vs. omission) and counterfactual thinking. Counterfactual thoughts partially mediated the effects of contextual variables and fairness perceptions in Study 1. Exploratory analyses from Study 3 revealed that the measurement of counterfactual thoughts (frequency vs. strength) may capture different underlying constructs. Implications are discussed.     

Modeling change in memory performance and memory perceptions: findings from the ACTIVE study

Within the context of the ACTIVE study, the current investigation explored the relationships between objective memory and two components of subjective memory (frequency of forgetting and use of external aids) over a five-year period. Relationships were assessed using parallel process latent growth curve models. Results indicated that changes in objective memory were associated with changes in perceived frequency of forgetting, but not with use of external aids (calendars, reminder notes) over time. Findings suggest that memory complaints may accurately reflect decline in objective memory performance, but that these memory changes are not necessarily related to compensatory behaviors.     

Deceived and distorted: game outcome retrospectively determines the reported time of action

Previous work suggested the association between intentionality and the reported time of action was exclusive, with intentionality as the primary facilitator to the mental time compression between the reported time of action and its effect (Haggard, Clark, & Kalogeras, 2002). In three experiments, we examined whether mental time compression could also be observed in an unintended action. Participants performed an externally cued key press task that elicited one of two possible tones. The reported time of action shifted closer to the tone when the tone was used to indicate the winner of a race (Exp.2) compared to when the tone was meaningless and did not indicate winning (Exp.1). This suggests that reported time of an unintended action could shift toward the effect in some contexts. Furthermore, the results from Exp.2 and Exp.3 (tones were substituted with verbal feedback) showed that a presumed winning action was judged to occur earlier whereas a presumed losing action was judged to be later. These findings therefore support the view that the reported time of action is reconstructed from known temporal information rather than determined by intentionality.     

Relationships among individualism--collectivism, gender, and ingroup/outgroup status, and responses to conflict: a study in China and the United States

Responses to conflict were studied in samples of college students from a highly collectivistic society (China, n = 207) and a highly individualistic society (United States n = 209). As predicted, the collectivistic society reported more conflict-reducing behaviors and less verbal or physical aggression. However, the effect of individualism/collectivism was moderated by both the ingroup/outgroup status of the target and gender of the participant. Chinese and US women did not differ on any measure. However, of the four groups, Chinese men reported the most conflict-reducing behaviors and the least physical aggression, whereas US men reported the fewest conflict-reducing behaviors and the greatest physical aggression. As predicted, conflict-reducing behaviors were more common in the ingroup condition and both verbal and physical aggression was more common in the outgroup condition. However, the latter were moderated by gender of the participant. US men reported greater physical aggression than any other group. Neither gender nor society had any effect on the level of indirect aggression. There were no gender or individualism/collectivism effects on indirect aggression. Observed gender effects were attributed to differences in how collectivistic and individualistic societies conceptualize masculinity. The effect sizes associated with the ingroup/outgroup condition were consistently and substantially larger than effect sizes associated with individualism/collectivism or gender.     

Taking a hands-on approach: apparent grasping ability scales the perception of object size

We examined whether the apparent size of an object is scaled to the morphology of the relevant body part with which one intends to act on it. To be specific, we tested if the visually perceived size of graspable objects is scaled to the extent of apparent grasping ability for the individual. Previous research has shown that right-handed individuals perceive their right hand as larger and capable of grasping larger objects than their left. In the first 2 experiments, we found that objects looked smaller when placed in or judged relative to their right hand compared to their left. In the third experiment, we directly manipulated apparent hand size by magnifying the participants' hands. Participants perceived objects to be smaller when their hand was magnified than when their hand was unmagnified. We interpret these results as demonstrating that perceivers use the extent of their hands' grasping abilities as "perceptual rulers" to scale the apparent size of graspable objects. Furthermore, hand size manipulations did not affect the perceived size of objects too big to be grasped, which suggests that hand size is only used as a scaling mechanism when the object affords the relevant action, in this case, grasping.     

Stereotype threat and female communication styles

A large body of research has documented the performance-debilitating effects of stereotype threat for individuals, but there is a paucity of research exploring interpersonal consequences of stereotype threat. Two experiments tested the hypothesis that stereotype threat would change the style in which women communicate. Results indicate that women who experience stereotype threat regarding leadership abilities react against the stereotype by adopting a more masculine communication style. Study 2 provides evidence that self-affirmation eliminates this effect of stereotype threat on women's communication styles. A third study demonstrates an ironic consequence of this effect of stereotype threat on women's communication--when women under stereotype threat adopt a more masculine communication style, they are rated as less warm and likeable, and evaluators indicate less willingness to comply with their requests. Theoretical and practical implications of these findings are discussed.
