Description
Individual differences in working memory capacity partly arise from variability in attention control, a process influenced by negative emotional content. Thus, individual differences in working memory capacity should be predictive of differences in the ability to regulate attention in emotional contexts.

Individual differences in working memory capacity partly arise from variability in attention control, a process influenced by negative emotional content. Thus, individual differences in working memory capacity should be predictive of differences in the ability to regulate attention in emotional contexts. To address this hypothesis, a complex-span working memory task (symmetry span) was modified so that negative arousing images or neutral images subtended the background during the encoding phase. Across three experiments, negative arousing images impaired working memory encoding relative to neutral images, resulting in impoverished symmetry span scores. Additionally, in Experiment 3, both negative and arousing images captured attention and led to increased hit rates in a subsequent recognition task. Contrary to the primary hypothesis, individual differences in working memory capacity derived from three complex span tasks failed to moderate the effect of negative arousing images on working memory encoding across two large scale studies. Implications for theories of working memory and attention control in emotional contexts will be discussed.

Intimate relationship functioning and mental well-being are inherently linked; thus, for those with mental illness, such as social anxiety, intimate relationship functioning may be impaired. Research on the intimate relationships of those with social anxiety has often focused on emotion regulation, as emotions play a crucial role in the development and maintenance of interpersonal relationships and are a clear area of deficit among those with social anxiety. The current thesis had three primary aims: 1a) to examine individual emotion expressivity and 1b) interpersonal emotion regulation processes among individuals with varying levels of social anxiety; 2) to examine individual and interpersonal emotion regulation within romantic relationships; and, 3) to examine how individual emotion expressivity and interpersonal emotion regulation influence relationship health and intimacy among those with varying levels of social anxiety. For Aim 1, differences in individual emotion expressivity and interpersonal emotion regulation were analyzed using regression analyses with social anxiety as a continuous predictor. Analyses were also conducted using a dichotomous grouping (i.e., non-socially anxious and socially anxious) and conducting a multivariate analysis of covariance (MANCOVA).

For Aim 2, the impact of individual and interpersonal emotion regulation processes on relationship health was examined using a series of regression analyses. Finally, Aim 3 was tested using structural equation modeling (SEM). Results suggest those with social anxiety show specific, but not general, deficits in individual emotion expressivity and interpersonal emotion regulation, and both individual and interpersonal emotion regulation had positive effects on relationship health. Regarding the primary analyses, interpersonal emotion regulation fully mediated the association between individual emotion expressivity and relationship health. Further, although the strength of these paths varied between groups, the valence and general pattern of these findings were similar for both those with social anxiety and those without. The study provided novel insights into the role of interpersonal emotion regulation in relationship health, and extended previous findings on emotion regulation and relationship health among those with social anxiety.

Emotion-related processes are a pivotal piece in establishing a holistic evaluation of interpersonal and intrapersonal outcomes due to stress. These processes are especially relevant for law enforcement officers (LEOs) who are required to regulate their emotions in the context of their personal lives and their job. The emotion suppression tendencies fostered by LEO culture may be exhibited in marital interactions, especially if LEOs perceive that their spouse does not understand their job (described here as spousal job misunderstanding [SJM]). The associations between LEOs believing their spouse misunderstands their job and their reported marital satisfaction and burnout levels may be explained through emotion suppression tendencies when with their spouse. This study examined whether the extent LEOs felt their spouse misunderstood their job was associated with marital satisfaction and burnout; whether those associations were mediated by the extent LEOs hid their feelings from their spouse; and, for burnout, whether effects were conditionally mediated at different levels of social support. Study analyses were conducted in separate groups according to gender, using survey data from 76 male and 26 female LEOs. In line with hypotheses, significant relationships between SJM and LEOs hiding their feelings were found. Mediation analyses revealed significant associations between SJM and marital satisfaction in both males and females, and this association was mediated by the extent LEOs hid their feelings from their spouse in male LEOs only. In a conditional mediation model, SJM was not associated with LEO burnout, but conditional indirect effects were found for male LEOs. Unexpectedly, indirect effects of LEOs hiding their feelings from their spouse were significant at mean and high levels of social support, but not at low levels. These results indicate the relevance of emotion regulation in the context of burnout, marital satisfaction, and social support, and how the opportunity for solving issues in policing and LEO-specific emotional difficulties may be found in novel interventions focused on these constructs.

Working memory capacity and fluid intelligence are important predictors of performance in educational settings. Thus, understanding the processes underlying the relation between working memory capacity and fluid intelligence is important. Three large scale individual differences experiments were conducted to determine the mechanisms underlying the relation between working memory capacity and fluid intelligence. Experiments 1 and 2 were designed to assess whether individual differences in strategic behavior contribute to the variance shared between working memory capacity and fluid intelligence. In Experiment 3, competing theories for describing the underlying processes (cognitive vs. strategy) were evaluated in a comprehensive examination of potential underlying mechanisms. These data help inform existing theories about the mechanisms underlying the relation between WMC and gF. However, these data also indicate that the current theoretical model of the shared variance between WMC and gF would need to be revised to account for the data in Experiment 3. Possible sources of misfit are considered in the discussion along with a consideration of the theoretical implications of observing those relations in the Experiment 3 data.
