Research on the correlates of maternal employment has yielded inconsistent results. In this study, 79 male and 120 female undergraduates with mothers who had been employed from the students' infancy through their adolescence scored higher on the Beck Depression Inventory-II than those whose mothers had not been employed. This relationship between children's depressive symptoms and mothers' employment history was not evident among young adults whose mothers' employment was perceived to be financially unnecessary.  相似文献

Two studies examined the connection between motivation for weight loss and autobiographical memory by comparing characteristics of autobiographical memories between dieters and non-dieters. Study 1 involved 29 normal/overweight dieters and 48 non-dieters, and Study 2 involved 18 obese dieters and 18 normal weight non-dieters. Memories recalled in response to dieting-related cue words were rated as more central to the person's identity and life story and contained more body- or weight-related elements for the dieters than the non-dieters. No differences between dieters and non-dieters were found on memories recalled in response to neutral cue words. The findings are discussed in relation to the notions of the working self (Conway & Pleydell-Pearce, 2000) and current concerns (Klinger, 1978).  相似文献

Theorists have long suggested that joint caregiver–child reminiscence is functional, in that it is useful, adaptive, and can be utilised to achieve a variety of goals in everyday life. In the present study we investigated caregiver reports of the functions of joint reminiscence across early childhood. Participants were 203 parents or other guardians of 2–6-year-old children. Caregivers completed the Caregiver–child Reminiscence Scale (CRS) designed to tap functions of joint reminiscence. Our results indicated that caregivers reported frequently talking about past experiences with their children. Exploratory factor analysis revealed seven functions of joint reminiscence: Emotion Regulation, Directive, Positive Emotionality, Individual Self in Relation to Others, Conversation, Cognitive Skills, and Peer Relationships. Although some of these functions map directly onto adult-like functions outlined in the theoretical literature, others are unique to the context of joint reminiscence and reflect developmental goals of the early childhood period.  相似文献

Studies in embodied cognition show that physical sensations, such as touch and movement, influence cognitive processes. Two studies were conducted to test whether squeezing a soft versus a hard ball facilitates different types of creativity. Squeezing a malleable ball would increase divergent creativity by catalyzing multiple or alternative ideas, whereas squeezing a hard ball would increase convergent creativity by facilitating only a single correct response. In Study 1, participants squeezed either a hard ball or a soft ball while completing the Torrance Test of Creative Thinking (TTCT), a divergent creativity test. The same procedures were used in Study 2 except that the TTCT was replaced with the Remote Associates Test, a convergent creativity test. Participants who squeezed a soft ball generated more original and diverse ideas (Study 1), whereas participants who squeezed a hard ball were better at coming up with a single correct answer (Study 2).  相似文献

This study examined the relationships between proactive personality and employee creativity and the moderating roles of job creativity requirement and supervisor support for creativity in activating proactive personality associated with employee creativity. To provide a rigorous test of the hypotheses, we conducted a field study from a sample of 157 employee–supervisor pairs in South Korea. The results revealed that a proactive personality was positively associated with employee creativity. In addition, job creativity requirement and supervisor support for creativity jointly influenced the relationship between proactive personality and employee creativity. Specifically, proactive employees exhibited the highest employee creativity when job creativity requirement and supervisor support for creativity were both high.  相似文献

The influence of vehicular control on motion sickness has implications for theories of motion sickness etiology. We asked whether motion sickness susceptibility might also be related to the control of non-vehicular locomotion. Participants were exposed to a console video game that featured ambulatory locomotion of a virtual avatar. In a yoked control design, individuals either played the game (players) or watched another participant's recorded game play (viewers). Viewers were more likely than players to report motion sickness. During exposure to the video game players moved more than viewers, and the movement of players was more predictable or self-similar than the movement of viewers. Coupling of movement within player-viewer pairs was greater for pairs in which the viewer later reported motion sickness than for pairs in which both participants stated that they were not motion sick. The results reveal that motion sickness incidence can be influenced by the control of stimulus motion, in general, and is not limited to control of vehicular motion. We discuss implications of these findings for theories of motion sickness etiology.  相似文献

In the present study we examined the impact of a comprehensive literacy instruction model called Collaborative Language and Literacy Instruction Project (CLLIP) on language and literacy achievement over the course of a year by Spanish‐speaking children in Chile. Participants included kindergartners (N = 312) from high and low socioeconomic backgrounds and first‐grade students (N = 305) from high SES families. The CLLIP model targeted phonological awareness, alphabetics and phonics, fluency, vocabulary, reading comprehension and writing, and included coaching and sustained follow‐up as key elements for teacher professional development. The results showed promise for the CLLIP model in the Chilean context. Kindergartners in CLLIP classrooms had faster growth rates in letter naming, word reading, vocabulary, and phonemic segmentation fluency than those in control classrooms, and had higher scores at the end of the year in phonemic segmentation fluency, letter naming, and word reading. In addition, kindergartners from high SES families had faster growth rates than kindergartners from low SES families in letter naming and word reading. Effect sizes ranged from small (d = .18 in word reading) to fairly large (d = .70 in letter‐naming fluency). First‐grade students in CLLIP classrooms had faster growth rates than students in control classrooms in vocabulary, nonword reading fluency, word reading, and reading comprehension. Effect sizes were small in vocabulary, nonword reading fluency, and reading comprehension (.23 ≤ d ≤ .28) and medium in word reading (d = .50). These results suggest that the present multicomponent literacy instructional model had a positive impact on Chilean children's literacy acquisition.  相似文献

Why do people consider cosmetic surgery? Based on the terror management theory, the present research identifies an existential motive: Through cosmetic surgery, people can symbolically defend against their death anxiety. A correlational study and an experiment showed that death terror, whether operationalized as individual differences in fear of death or experimentally manipulated mortality salience, was associated with stronger acceptance of cosmetic surgery. This association was absent among participants who did not consider physical appearance important, and weaker among those who were satisfied about their appearance. Also, this association was particularly strong among those with high explicit self‐esteem. This concurs with the recent theoretical development about the role of self‐esteem in symbolic defenses against death terror.  相似文献

This paper explores trust of mobile applications based on users' behaviors. It proposes a trust behavior construct through principal component analysis, reliability analysis, and confirmatory factor analysis based on the data collected from a questionnaire survey with more than 1,500 participants. It is indicated that a user's trust behavior is composed of three principal constructs: using behavior, reflection behavior, and correlation behavior. They are further delineated into 12 measurable sub‐constructs and relate to a number of external factors. The data analysis showed that the questionnaire has positive psychometric properties with respect to construct validity and reliability. We also discuss the practical significance and limitations of our work toward usable trust management.  相似文献

Generalised anxiety disorder (GAD) responds well to individually delivered metacognitive therapy (MCT). The current study investigated the effectiveness of MCT administered to groups of patients with GAD in a general outpatient treatment centre. Thirty-three consecutively referred adult patients with GAD were assessed before treatment (pretreatment), after the last treatment session (posttreatment), and six months after treatment had ended (follow-up). Analyses of treatment effects were conducted for all patients entering the study (i.e., intent-to-treat analysis, using the last-observation-carried-forward procedure), and repeated for the patients who completed treatment (completers analysis), using paired samples t-tests. Further, effect sizes (ESs) and indices of clinical significance were calculated, and compared with those reported in studies into the efficacy and effectiveness of individually delivered MCT for GAD. Among both the intent-to-treat and the completers sample, large pre- to posttreatment reductions in symptoms of worry, trait-anxiety, and general psychopathology. The magnitude of change and the degree of clinical significance were smaller than those reported in studies into the effectiveness of individually delivered MCT for GAD, whereas the attrition rate (27 %) was higher. It is tentatively concluded that MCT for GAD can be effectively delivered in a group format in a heterogenous clinical practice setting. Further evaluation is clearly indicated.  相似文献
