Recent research suggests that examining humor styles may contribute to our understanding of clinical problems, such as risk and resiliency. The goal of the current study was to examine whether humor styles moderate the association between social anxiety and depressive symptoms in an unselected sample. Three-hundred and six participants (66% female) at a large Southern US university completed self-report measures of humor styles and symptoms of social anxiety and depression. Regression analyses suggested that affiliative and self-defeating humor styles individually moderated the relationship between social anxiety and depressive symptoms. Clinical implications regarding the monitoring of humor use as a means of understanding the maintenance of depressive symptoms among socially anxious individuals are discussed.  相似文献

Abstract

Couples who are given property by their parents as a wedding gift or as a gift a little later in the marriage appear to start off their marriages with a bonus that any couple would certainly envy. Often, however, the “given” property has strings attached and the “lucky” couple finds themselves in emotional mortgage to one of their parents. Emotional mortgage is seen as a debt of loyalty and obligation owed to one of the spouse's parents which places the couple in a position of servitude in regard to those parents. The expectation of eventual ownership of property appears to be the mechanism which binds the couple to the parents in the face of countless intrusions and usurpations by the parents.  相似文献

An evolutionary approach to attractiveness judgments emphasises that many human trait preferences exist in order to assist adaptive mate choice. Here we test an adaptive development hypothesis, whereby voice pitch preferences indicating potential mate quality might arise or strengthen significantly during adolescence (when mate choice becomes adaptive). We used a longitudinal study of 250 adolescents to investigate changes in preference for voice pitch, a proposed marker of mate quality. We found significantly stronger preferences for lower-pitched opposite-sex voices in the older age group compared with the younger age group (using different sets of age-matched stimuli), and marginally increased preferences for lower-pitched opposite-sex voices comparing within-participant preferences for the same set of stimuli over the course of 1 year. We also found stability in individual differences in preferences across adolescence: controlling for age, the raters who had stronger preferences than their peers for lower-pitched voices when first tested, retained stronger preferences for lower-pitched voices relative to their peers about 1 year later. Adolescence provides a useful arena for evaluating adaptive hypotheses and testing the cues that might give rise to adaptive behaviour.  相似文献

Developmental transitions are imbued with ubiquitous uncertainties that undermine goal striving in many otherwise committed individuals. Our seven-month study examined whether cognitive selective secondary control strategies (motivation-focused thinking) facilitate the enactment of achievement goals among young adults experiencing the landmark school to university transition. Sequential regression analyses demonstrated that (a) achievement goals predicted selective secondary control, (b) selective secondary control predicted behavioral selective primary control striving, and (c) selective primary control predicted final course grades. Findings support Heckhausen et al.'s (2010 Heckhausen , J. , Wrosch , C. , &; Schulz , R. ( 2010 ). A motivational theory of life-span development . Psychological Review , 117 , 3260 .[Crossref], [PubMed], [Web of Science ®] [Google Scholar]) proposition that selective secondary control bolsters selective primary control striving and enables goal attainment during difficult transitions.  相似文献

In drawing on my own research and collaborative work with Karl Pribram, I show that love (affective attachment) and power (social control) play a central role in psychosocial evolution. When these relations are coupled in a self-regulating system of cooperative interactions, brain growth is stimulated, mind and agency develop, and stable forms of collective social organization are generated. Focusing on the endogenous dynamics of social collectives, the article is organized in four parts. (A "social collective" is defined as a durable arrangement of relations among two or more individuals that is distinguished by shared membership and collaboration in relation to a common function or goal.) Part I summarizes evidence from developmental neuropsychology and social science to show that stable psychosocial organization, across the human life span, is associated with social interaction organized along two dimensions. One dimension involves love, positive affective attachment, and the second involves power, social regulation of the aroused affective energy. Part II draws on Piaget's theory of cooperation and Bradley and Pribrams' theory of communication to describe how mind and agency are generated, and how stable organization is produced, respectively, from the relations involved in the arousal and regulation of affective energy. Combining elements of the two theories, Part III presents a sketch of a holographic model of collective organization in which goal-directed behavior is generated by a feed-forward process involving imaging and information processing of interaction along the two dimensions. Part IV shows how the model accounts for the emergence of human agency within the context of a more general evolutionary theory, such as Laszlo's. The article concludes with a discussion of my approach for building a "fully human theory of evolution."  相似文献

Bistable, autonomously growing and self‐maintaining dynamical systems possess a new mathematical and applicational aspect: they can switch toward (physical) existence. Larger dynamical systems containing such flip‐flops as subsystems are frequent. The mathematical prototype is a special type of Z2‐networks, termed a competence automaton. A chemical implementation is the ‘magic soup.’ It constitutes a general model for life‐type evolution processes including economic evolution.  相似文献

Visual working memory (WM) for face identities is enhanced when faces express negative versus positive emotion. To determine the stage at which emotion exerts its influence on memory for person information, we isolated expression (angry/happy) to the encoding phase (Experiment 1; neutral test faces) or retrieval phase (Experiment 2; neutral study faces). WM was only enhanced by anger when expression was present at encoding, suggesting that retrieval mechanisms are not influenced by emotional expression. To examine whether emotional information is discarded on completion of encoding or sustained in WM, in Experiment 3 an emotional word categorisation task was inserted into the maintenance interval. Emotional congruence between word and face supported memory for angry but not for happy faces, suggesting that negative emotional information is preferentially sustained during WM maintenance. Our findings demonstrate that negative expressions exert sustained and beneficial effects on WM for faces that extend beyond encoding.  相似文献

The current studies investigated age-related biases in recall of emotion in older and younger adults. In two prospective–retrospective, Internet-based diary studies, older (aged 65 years and older) and younger participants (aged 18 to 37) reported on their affect at the end of every day. Participants then recalled their affect during the diary rating periods. In both studies, recall bias was assessed by comparing retrospective reports to the prospective diary ratings. Older adults tended to overestimate positive affect more than younger adults, who themselves tended to overestimate negative affect more than older adults, relative to diary ratings. Age-related patterns of recall bias are discussed in light of recent literature on the interface between cognition and emotion in ageing, particularly on increased positivity and reduced negativity effects in emotional processing and recall.  相似文献

Numeracy is the understanding of the meaning and interpretation of natural phenomena and is an important skill for full participation in society. Everyday there are numerous situations that require individuals to interpret quantitative information for personal decision making and understanding of significant public issues. However, the gap between individuals’ numeracy needs and their understanding of numeracy has widened. Thus, organizations and scholars have attempted to explain the value and nature of numeracy. This article discusses how and why numeracy is important for full participation in society.  相似文献

Many studies have documented systematic shifts in women’s mate preferences and sexual motivations across the ovulatory cycle. Harris (2012) presents a nonreplication of one particular finding in this literature—namely, that women’s preference for masculinity in men’s faces shifts across the cycle. Harris critiques the empirical and theoretical literature on cycle shifts and concludes that the cycle shift hypothesis should be abandoned. Here, we situate Harris’s findings within the broader empirical literature and respond to several of the points in her critique. We conclude that the evidence for cycle shifts in women‘s mate preferences and sexual motivations is much stronger than Harris portrays and that she mischaracterizes the theoretical basis of this work.  相似文献
