Avoidance behavior associated with depressive symptoms in patients with implantable cardioverter defibrillators

Objective: Many patients with implantable cardioverter defibrillators experience depressive symptoms. In addition, avoidance behavior is a common problem among patients with implantable cardioverter defibrillators. We examined the association between avoidance behaviors and depressive symptoms in patients with implantable cardioverter defibrillators. Method: We conducted a single-center, cross-sectional study with self-completed questionnaires between May 2010 and March 2011. We measured avoidance behaviors (avoidance of places, avoidance of objects, and avoidance of situations) and depressive symptoms (using the Beck Depression Inventory, Version II) in 119 participants. An avoidance behaviors instrument was developed for this study and we confirmed its internal consistency reliability. Results: Ninety-two (77.3%) patients were aged older than 50 years, and 86 (72.3%) were men. Fifty-one (42.9%) patients reported “avoidance of places”, 34 (28.6%) reported “avoidance of objects”, and 63 (52.9%) reported “avoidance of activity”. Avoidance behavior was associated with increased odds for the presence of depressive symptoms (OR 1.31; 95% CI 1.06–1.62). Conclusions: This was the first study to identify the relationship between avoidance behavior and depressive symptoms among patients with implantable cardioverter defibrillators; however, there are a few methodological limitations.     

Usage of semantic representations in recognition memory

Meanings of words facilitate false acceptance as well as correct rejection of lures in recognition memory tests, depending on the experimental context. This suggests that semantic representations are both directly and indirectly (i.e., mediated by perceptual representations) used in remembering. Studies using memory conjunction errors (MCEs) paradigms, in which the lures consist of component parts of studied words, have reported semantic facilitation of rejection of the lures. However, attending to components of the lures could potentially cause this. Therefore, we investigated whether semantic overlap of lures facilitates MCEs using Japanese Kanji words in which a whole-word image is more concerned in reading. Experiments demonstrated semantic facilitation of MCEs in a delayed recognition test (Experiment 1), and in immediate recognition tests in which participants were prevented from using phonological or orthographic representations (Experiment 2), and the salient effect on individuals with high semantic memory capacities (Experiment 3). Additionally, analysis of the receiver operating characteristic suggested that this effect is attributed to familiarity-based memory judgement and phantom recollection. These findings indicate that semantic representations can be directly used in remembering, even when perceptual representations of studied words are available.     

违规和违法行为责任归咎的身份效应——基于官员、富人与普通人间的比较分析

为探讨违规和违法事件中,旁观者对不同社会身份行为者的责任归咎是否具有一致性,研究要求被试对三组不同身份匹配条件下(官员/普通人、富人/普通人以及官员/富人)的违规和违法行为进行责任归咎,结果发现,无论是对违规行为,还是对违法行为,人们对具有官员身份的行为者的责任归咎最为严苛,对具有富人身份的行为者的责任归咎其次,而对既非官员也非富人的普通人的责任归咎则相对宽容,因而责任归咎中具有明显的身份效应。     

The Mediating Effects of Self-Esteem and Trait Anxiety Mediate on the Impact of Locus of Control on Subjective Well-Being

Sense of control plays an important role in the psychological well-being of an individual. This study aims to investigate the impact of locus of control on subjective well-being (SWB). Participants include 400 undergraduates (214 men and 186 women) from four universities in China. Data were collected using the Adult Nowicki-Strickland Internal-External Locus of Control Scale, Rosenberg Self-Esteem Scale, Trait Anxiety Scale, and SWB measures. Results suggested that locus of control, trait anxiety, and self-esteem were significantly correlated with SWB. Structural equation modeling results indicated that trait anxiety and self-esteem partially mediated the impact of locus of control on SWB. Moreover, bootstrap test revealed significant paths from locus of control to SWB through trait anxiety and self-esteem. Therefore, locus of control, trait anxiety, and self-esteem have significant impacts on SWB. Moreover, trait anxiety and self-esteem have a mediating effect on the impact of locus of control on subjective well-being.     

Music's Effect on Exercise Participants by Exercise Session

We identified exercise participants’ music preferences in three exercise sessions and clarified how preferred or randomly assigned music affects perceived psychological helpfulness of exercise. There were 292 fitness center members in Korea who were selected as participants. Participants’ preferred music was assessed using frequency analysis and participants were grouped by preferences. Similar percentages were observed for sedative (45.2%) and stimulative (54.8%) music during warm-up, whereas participants preferred stimulative (91.4%) and sedative (75.7%) music during workout and cooldown, respectively. During the warm-up session, sedative music was found to be more psychologically helpful for the sedative music preferred group (t = 4.86, p <.001), whereas stimulative music was found to be significantly more psychologically helpful than sedative music for the stimulative music–preferred group (t = –6.47, p <.001). During the workout sessions, the sedative music was found to be more helpful for the sedative music–preferred group, albeit with no statistical difference from stimulative music, whereas the stimulative music had similar effects to the warm-up session (t = ?18.37, p <.001). Finally, during the cool-down sessions, sedative music was found to be more psychologically helpful for the sedative music­–preferred group (t = 7.97, p <.001), whereas stimulative music was found to be more psychologically helpful to the stimulative music–preferred group (t = ?2.10, p <.05). The results of this study provide basic information for music usage in health management centers and other interested organizations to improve physical activity.     

Direct and Indirect Effects of Self-efficacy on Depression: The Mediating Role of Dispositional Optimism

In this study, we aimed to explore the impact of self-efficacy on depression – specifically, to test and verify the mediating role of dispositional optimism between the two variables. Five hundred and thirty-five undergraduates from two universities were recruited and given a Self-Efficacy Questionnaire, Revised Life Orientation Test, and Self-Rating Depression Scale. Results indicated that there are indeed significant relationships among self-efficacy, dispositional optimism, and each identified dimension of depression; structural equation modeling showed that the relationship between self-efficacy and depression is partially mediated by dispositional optimism. To this effect, we concluded that to develop and improve students’ self-efficacy will reduce their levels of depression, which may have implications in college counseling.     

Rumination and dysphoria: The buffering role of adaptive forms of humor

The current study examines the effects of rumination and humor on individuals’ dysphoria level. Measures of humor (affiliative and self-enhancing), rumination, and depressive symptoms were completed by 303 undergraduate students. Consistent with our hypothesis, both affiliative humor and rumination independently accounted for variance in dysphoria levels. In addition, self-enhancing humor and rumination were independently associated with dysphoria. Moreover, significant interactions between affiliative humor and rumination, and self-enhancing humor and rumination, on dysphoria also emerged. Results indicated that among individuals with high rumination, those with high affiliative and/or self-enhancing humor had significantly lower levels of dysphoria than individuals with low affiliative and/or self-enhancing humor. The combination of low affiliative and/or self-enhancing humor and high rumination led to substantially higher levels of dysphoria than any other combination. Implications for psychotherapy and research in this area are discussed.

心理学非人性化和人性化的矛盾与冲突

心理学自1879年独立以来,由于种种原因,其发展一直存在着非人性化与人性化的矛盾与冲突,而这种矛盾与冲突所带来的最严重的后果是导致心理学出现了分裂,心理学成为了一门学派纷争、理论对立、组织分裂的学科。该文着重分析了心理学的两大研究范式间和科学主义心理学本身中所存在的非人性化与人性化的矛盾与冲突,希望借此能对我国心理学的发展有所启示。
