Interaction of knowledge-driven and data-driven processing in category learning

The present paper argues that category learning is both a data-driven and a knowledge-driven process. This is described in a generic model that distinguishes between categorical knowledge, conceptual knowledge, and implicit cognitive theories. The model assumes that each of these knowledge aspects may affect the process of category learning by affecting the way similarities between objects are perceived. This central assumption of the model is tested in two experiments. The first experiment shows that the presence or absence of prior categorical and conceptual knowledge affects the psychological stimulus space by changing the saliency of the stimulus dimensions. The second experiment uses these weights to predict the distribution of errors over the stimuli and the number of trials to criterion in category learning by other participants under the same knowledge conditions. We conclude that prior categorical and conceptual knowledge affect category learning by mediation of similarity perception, and discuss the implications of these results.     

Beyond Viral: Interpersonal Communication in the Internet Age

Contemporary scholarship on mindfulness casts it as a form of purely nonevaluative engagement with experience. Yet, traditionally mindfulness was not intended to operate in a vacuum of dispassionate observation, but was seen as facilitative of eudaimonic mental states. In spite of this historical context, modern psychological research has neglected to ask the question of how the practice of mindfulness affects downstream emotion regulatory processes to impact the sense of meaning in life. To fill this lacuna, here we describe the mindfulness-to-meaning theory, from which we derive a novel process model of mindful positive emotion regulation informed by affective science, in which mindfulness is proposed to introduce flexibility in the generation of cognitive appraisals by enhancing interoceptive attention, thereby expanding the scope of cognition to facilitate reappraisal of adversity and savoring of positive experience. This process is proposed to culminate in a deepened capacity for meaning-making and greater engagement with life.     

Occupational stress,psychological burnout and anxiety

Abstract

For many decades, the stress process was described primarily in terms of negative emotions. However, robust evidence that positive emotions co-occurred with negative emotions during intensely stressful situations suggested the need to consider the possible roles of positive emotions in the stress process. About 10 years ago, these possibilities were incorporated into a revision of stress and coping theory (Folkman, 1997). This article summarizes the research reported during the intervening 10 years that pertains to the revised model. Evidence has accumulated regarding the co-occurrence of positive and negative emotions during stressful periods; the restorative function of positive emotions with respect to physiological, psychological, and social coping resources; and the kinds of coping processes that generate positive emotions including benefit finding and reminding, adaptive goal processes, reordering priorities, and infusing ordinary events with positive meaning. Overall, the evidence supports the propositions set forth in the revised model. Contrary to earlier tendencies to dismiss positive emotions, the evidence indicates they have important functions in the stress process and are related to coping processes that are distinct from those that regulate distress. Including positive emotions in future studies will help address an imbalance between research and clinical practice due to decades of nearly exclusive concern with the negative emotions.     

The role of meaning in gastric cancer patients: relationships among meaning structures,coping, and psychological well-being

ABSTRACT

Background and Objectives: Research demonstrates that the experience of cancer invariably violates patients’ meaning structures, prompting them to use coping strategies to alleviate stress and enhance well-being. The current study aimed to examine the mediating effects of coping strategies in the relationship between global and situational meaning and psychological well-being in gastric cancer patients.

Design and Method: One hundred eighty-seven patients (96 women and 91 men) with gastric cancer completed questionnaires measuring meaning in life, changes of beliefs and goals, coping, and psychological well-being. Participants were between 27 and 82 years of age. They were diagnosed with gastric cancer from 1 to 3.2 years ago. Using Structural Equation Modeling, both the direct and indirect associations between meaning structures, coping, and psychological well-being were examined.

Results: Meaning in life exerted significant indirect effects on psychological well-being through three coping strategies: problem-, emotion-, and meaning-focused. The relationship between changes of beliefs and goals and psychological well-being was also mediated by coping.

Conclusions: Findings suggest that coping strategies are mediators in the relationship between global and situational meaning and psychological well-being. They also provide empirical evidence that in severe cancer-related stress conditions both meaning structures and coping strategies influence patients’ psychological well-being.     

Patterns of situational appraisal in experiences of worry and anxiety

Abstract

Three studies investigating differences in people's appraisals of worry and anxiety situations are presented. First, data from a study by Reisenzein & Spielhofer (1994) were reanalyzed. Second, two further studies were conducted to replicate the findings of the reanalysis and to explore whether any additional appraisal dimensions were relevant for a differentiation of worry and anxiety situations. In sum, results showed that appraisals associated with situations in which worry and anxiety were experienced differed on eight appraisal dimensions. Compared to experiences of anxiety, experiences of worry were more often associated with positive self-evaluation, positive social-relationship evaluation, feelings of closeness, and sentiments of importance, and less often associated with feelings of inferiority. Moreover, in worry experiences, focus was often not on the self, but on other persons. Finally, with respect to temporal dimensions, worry situations were less often associated with notions of suddenness and momentariness than anxiety situations. Implications of these findings are discussed with respect to models of emotional appraisal and research on worry and generalized anxiety disorder.     

Social anxiety and the experience of positive emotion and anger in everyday life: an ecological momentary assessment approach

Abstract

A few recent studies have found evidence showing that social anxiety is associated with diminished positive affect and elevated anger. However, prior work has relied on trait self-report measures of global positive mood or anger. In this preliminary study, we examined how trait social anxiety relates to moment-to-moment positive and angry emotional states as people navigate through their natural environment in a given day. Of additional interest was whether any associations were limited to social situations or were evident more broadly in non-social situations as well. For 14 days, 38 non-clinical community adults carried electronic diaries to assess their experience of positive emotions, anger, and their current social context and activity. Participants were randomly prompted up to four times per day, leading to 1702 observations. Results showed that social anxiety was associated with less time spent feeling happy and relaxed and more time spent feeling angry throughout the day. In general, people felt happier when they were with other people compared to being alone. Interestingly, people with relatively higher levels of social anxiety reported fewer and less intense positive emotions and greater anger episodes across social and non-social situations.     

The other side of rumination: reflective pondering as a strategy for regulating emotions in social situations

Recent studies have questioned the idea of rumination as a unitary dysfunctional process and identified an adaptive subcomponent: reflective pondering. We tested whether reflective pondering could represent an adaptive strategy of regulating emotions, and contrasted it with reappraisal and acceptance, strategies linked to major psychotherapeutic approaches. Participants (103 students) received training in one of these and were exposed to a negative mood induction consisting of social scenarios, both in the presence and in the absence of the specific emotion regulation instruction. Acceptance was more useful than reflective pondering in impacting negative emotions and anxiety. Reappraisal was more efficient than pondering for anxiety. However, moderation analysis showed that social anxiety (SA) levels influenced the comparative efficiency of reappraisal and acceptance as contrasted to reflective pondering for negative emotions and anxiety. Participants low in SA made equal use of all strategies, while for those high in SA reappraisal and acceptance were more efficient than pondering. Our results provide preliminary evidence that reflective pondering can, in some circumstances, be an adaptive regulation strategy.     

A multi-modal investigation of the roles of distress tolerance and emotional reactivity in obsessive-compulsive symptoms

Emerging evidence implicates important roles of poor distress tolerance and heightened emotional reactivity in obsessive-compulsive disorder. To date, investigations have relied mostly on self-report measures, and we sought to extend the literature by examining the relationship between OC symptoms and distress tolerance, as well as emotional reactivity, using three laboratory assessments. Nonclinical participants (N=167) viewed emotional films associated with four different negative emotions and also completed mirror tracing and handgrip persistence tasks. Greater obsessions scores were predictive of poorer emotional tolerance for a sad film and shorter persistence on the mirror tracing task. Among men only, obsessions were negatively correlated with persistence on the handgrip task. Associations between increased emotional reactivity and washing symptoms also emerged. These findings provide further evidence for the role of poor distress tolerance in obsessions and suggest heightened emotional reactivity may play a role in compulsive washing.     

A Preliminary Examination of Thought Suppression,Emotion Regulation,and Coping in a Trauma-Exposed Sample

Attempts to modulate negative emotional and cognitive symptoms of posttraumatic stress disorder (PTSD) may be related to psychopathology. Trauma-exposed undergraduates, 31 reporting severe PTSD symptoms (PTSD group) and 34 without PTSD symptoms (non-PTSD group), completed measures of PTSD, depression, anxiety, thought control, emotion regulation, and coping. The PTSD group had greater psychopathology and overall modulation strategy use than the non-PTSD group. Thought suppression, emotion suppression, and avoidant coping strategies were positively related to psychopathology, whereas emotion reappraisal and approach coping strategies were either not related or weakly negatively related. Hierarchical multiple regressions with psychopathologic variables as criteria and modulation strategies as predictors indicated significant models in all cases. Generally, thought suppression was the only significant independent predictor of psychopathology.     

Internalized Homophobia and Intimate Partner Violence in Young Adult Women’s Same-Sex Relationships

This study examined the relationship between intimate partner violence (IPV), internalized homophobia, and psychological maladjustment in a convenience sample of young adult women. Rates of psychological and physical abuse in women’s same-sex relationships were shown to be commensurate to previously reported rates of violence in the IPV literature; rates of sexual coercion were also ascertained. A relationship was found between Moral and Religious Attitudes Toward Lesbianism (MRATL), a dimension of internalized homophobia, and the perpetration of sexual coercion. As expected, internalized homophobia was connected to psychological maladjustment. In addition, both the perpetration of psychological aggression and physical violence were associated with emotional instability. The study findings are discussed within the current body of literature on IPV.
