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

Past research has consistently found that people are likely to do worse on high‐level cognitive tasks after exerting self‐control on previous actions. However, little has been unraveled about to what extent ego depletion affects subsequent prospective memory. Drawing upon the self‐control strength model and the relationship between self‐control resources and executive control, this study proposes that the initial actions of self‐control may undermine subsequent event‐based prospective memory (EBPM). Ego depletion was manipulated through watching a video requiring visual attention (Experiment 1) or completing an incongruent Stroop task (Experiment 2). Participants were then tested on EBPM embedded in an ongoing task. As predicted, the results showed that after ruling out possible intervening variables (e.g. mood, focal and nonfocal cues, and characteristics of ongoing task and ego depletion task), participants in the high‐depletion condition performed significantly worse on EBPM than those in the low‐depletion condition. The results suggested that the effect of ego depletion on EBPM was mainly due to an impaired prospective component rather than to a retrospective component.  相似文献

The purpose of this study was to examine links between parenting dimensions (authoritative parenting, psychological control, and parental authority) and adolescent wellbeing (self‐esteem, autonomy, and peer attachments) as mediated by parent–teen attachment, among Chinese families. The sample included 298 Chinese adolescents, ages 15–18 years (M age = 16.36, SD = .68; 60% female). The mediation model was examined using path analyses (one model with parental authority as overprotection, and one with it as perceived behavioral control). To improve model fit a direct path was added from authoritative parenting to autonomy. Authoritative parenting was positively predictive of attachment, while psychological control and overprotection (but not behavioral control) were negative predictors. In turn, adolescent–parent attachment was positively related to the three outcomes. Lastly, the model paths did not differ by adolescent gender. These findings suggest that parenting behaviors may play a crucial role in adolescent social behaviors and wellbeing via adolescent–parent attachment.  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

Most impulse purchasing research investigates individual‐level factors. This paper, however, examines the influence of shopping companion gender on impulse purchasing. The results of the three studies show that shoppers were more likely to exhibit impulse purchase behavior when shopping with an opposite gender companion. In addition, shoppers who were in the low‐cohesive condition and who shopped with an opposite gender companion were more likely to exhibit impulse purchase behavior than those who shopped with the same gender companion, and those who were susceptible to interpersonal influence were also more likely to exhibit impulse purchase behavior when shopping with an opposite gender companion. For shoppers who were not as susceptible to interpersonal influence, the influence of their companion's gender appeared to diminish on impulsive purchasing.  相似文献

Immigrants' sense of self can be derived both from being members of their ethnic in‐group and their country of residence. We examined how the ways in which immigrant adolescents integrate these self‐views in relation to academic success in German schools. Students describe themselves at school and when with family. Using a standardized literacy performance test, analyses revealed that immigrants whose school‐related self‐view did not include Germany were less successful: Students who described their self as including both aspects of their ethnic group and Germany, and students who saw themselves predominantly as German, outperformed students with purely ethnic school‐related selves. As expected, though, an ethnic family‐related self‐view did not have a negative impact on scholastic achievements.  相似文献

In this study, we examined possible connections between perceived emotional intelligence (PEI) and effectiveness during the negotiation process in a sample of 123 workers from different organizations. Participants completed a set of questionnaires, including an exploration of the predictive and incremental validity of PEI measured by Trait‐Meta‐Mood Scale. Moreover, personality traits were carefully controlled to test the percentage of variance that PEI accounted for in efficiency during negotiation. Multiple regression analyses revealed that emotional repair accounts for part of the variance in the balance of power and in procedural flexibility that cannot be explained by personality traits alone. Thus, our results show that emotional repair accounts for negotiation effectiveness in a way that is independent of personality traits.  相似文献

In today's competitive workplace, individuals who are best prepared will have the greatest chance of obtaining and retaining jobs. Students can better prepare by developing the maximum possible knowledge and skills during their college educations. Research has shown that attitudes and perceptual variables have significant effects on development activity in organizations. We extend that research by using structural equations modeling to examine influences on attitudes toward one's college education. We posited that Big Five personality factors influence personal growth, readiness to change, and the perceived instrumentality of a university education and that these factors influence attitudes toward education. Results supported the posited model. A better understanding of antecedents of attitudes can enhance educational intervention effectiveness.  相似文献

Abstract

This paper will examine the current crisis in psychoanalysis in terms of the profession's decline, the apparent lack of patients, the ongoing debate over what constitutes psychoanalysis versus other therapies, and the lack of clinical focus in those debates. The concept of analytic contact will be introduced, and clinical material is used to showcase this concept as a bridge from the circular political debates to a more meaningful examination of what is psychoanalytic. In addition, case material will explore how patients tend to fight off the establishment of analytic contact in favor of safer, less threatening modes of relating. The author suggests that most patients fight off analytic contact and try to shift the treatment into something less analytic. It is up to the analyst to detect this, interpret it, and notice any countertransference collusion that may occur. Although the state of psychoanalysis as a profession is less than stellar in the eyes of the public, and the profession is apt to sabotage itself with endless debates about what constitutes true analytic work, the end is not necessary near. This paper proposes analytic contact to be the more useful focus of research and productive area of clinical exploration. If the decline of our field is to turn around, it will be on the clinical battlefront, not in terms of the theorizing among disagreeing groups of territorial analysts afraid of losing their political high-ground. The concept of analytic contact assumes that a deep exploration of intrapsychic phenomena, conflicts, and defenses, all within the realm of the transference, is the best clinical method of helping the mentally troubled individual. This genuine chance of change is best administered by a trained psychoanalyst. This simple idea is something the profession has contaminated with its often pointless arguments over frequency, analyzability, couch, and so forth. The clinical material will show that what happens in the room between analyst and patient is what best defines the true psychoanalytic treatment.  相似文献

This cross‐sectional study investigated the significant differences in students’ self‐efficacy and their involvement in learning science. Nine hundred and twenty‐two elementary school fifth graders, 499 junior high school eighth graders, and 1455 senior or vocational high school eleventh graders completed the students’ questionnaire. Analyses of variance (ANOVAs) and independent t‐tests compared the significant similarities and differences across school levels and genders. The initial findings were as follows: A sharp decline in boys’ and girls’ self‐efficacy scores from elementary to secondary school levels; boys have significantly higher self‐efficacy scores than girls at vocational and senior high school levels; students with more involvement in science learning presented significantly higher self‐efficacy scores than those with less involvement. The significant discrepancies in terms of gender and age in students’ self‐efficacy and involvement in learning science need to be addressed. Implications and limitations are provided.  相似文献
