Two brief intervention studies tested whether teaching students to mentally contrast a desired future with its present reality resulted in better academic performance than teaching students to only think about the desired future. German elementary school children (N = 49; Study 1) and US middle school children (N = 63; Study 2) from low-income neighborhoods who were taught mental contrasting achieved comparatively higher scores in learning foreign language vocabulary words after 2 weeks or 4 days, respectively. Results have implications for research on the self-regulation of commitment to solve assigned tasks in classroom settings, and for increasing academic performance in school children in low-income areas.  相似文献

This study investigated the most effective way to present an instructional video that contains words in the students' second language. Korean‐speaking university students received a 16‐min video lesson on Antarctica that included English narration (video + narration group), English text subtitles (video + text group), or English narration with simultaneous text subtitles (video + narration + text group). On a comprehension test, the video + text group scored higher than each of the other two groups, in contrast to the modality effect; and the video + narration + text group outscored the video + narration group, in contrast to the redundancy effect. Each of the lessons that included text was rated as less difficult than the lesson with narration only. The narration + text group reported lower effort than each of the other groups. Results highlight boundary conditions for two principles of multimedia instructional design that apply for college students who are learning in a second language. Theoretical implications are discussed.  相似文献

The present study examined punishment of responding with histamine injection, and its potential to generate avoidance of punishment. Sprague–Dawley rats were trained under concurrent schedules in which responses on one lever (the punishment lever) produced food under a variable‐interval schedule, and under some conditions intermittent injections of histamine, which suppressed behavior. Responses on a second (avoidance) lever prevented histamine injections scheduled on the punishment lever. After stabilization of punished responding, a variable‐interval 15‐s schedule of cancellation of histamine (avoidance) was added for responding on the second/avoidance lever, without subsequent acquisition of responding on that lever. Progressive decreases in the length of the punishment variable‐interval schedule increased suppression on the punishment lever without increases in response rates on the avoidance lever. Exchanging contingencies on the levers ensured that response rates on the avoidance lever were sufficiently high to decrease the histamine injection frequency; nonetheless response rates on the avoidance lever decreased over subsequent sessions. Under no condition was responding maintained on the avoidance lever despite continued punishing effectiveness of histamine throughout. The present results suggest that avoidance conditioning is not a necessary condition for effective punishment, and confirm the importance of empirical rather than presumed categorization of behavioral effects of stimulus events.  相似文献

This study investigated the extent to which the link between perceived social support and affect reflected support recipients' trait perceived support as well as three distinct social processes: the objective supportiveness of providers, the unique relationships among recipients and providers that were stable over occasions, as well as the unique relationships that varied across occasions. Ten recipients interacted with each of the same four providers on five separate occasions, for a total of 200 interactions. Recipients and independent observers rated recipient affect and provider support. Greater perceived support was related to greater positive affect for recipients' trait perceived support, as well as for relationships that were stable over occasions and relationships that varied across occasions. No social support effects were found for negative affect. Perceived similarity was a consistent predictor of recipients' support perceptions. Implications for social support models and interventions were discussed.  相似文献

This paper presents the advantages of a comprehensive Operationalized Psychodynamic Diagnostic in childhood and adolescence (OPD-CA) for subsequent treatment planning. Information about the conflict and structural axes as a function of age, gender, diagnosis and proposed form of treatment (outpatient/inpatient) was analyzed in a group of 116 patients. Independent from the diagnosis, a similar ranking in the importance of conflicts was found. Self-esteem conflicts were more prominent for inpatient children and adolescents and identity conflicts were more prevalent in children and adolescents who were at the start of outpatient therapy. Patients with an indication for inpatient treatment had a significantly lower level in all structural dimensions. This study analyzes the reasons for these findings.  相似文献

Endovascular therapy of acute ischemic stroke represents a supplementary or (in cases of contraindications to systemic lysis) alternative therapy option to intravenous thrombolysis for patients with severe clinical deficits and proximal vascular obstruction. Currently, (in cases with no contraindications to systemic lysis) the combination with mechanical thrombectomy in the form of so-called stent retrievers has proven to be effective and safe. Until superiority over intravenous thrombolysis alone has been proven in certain patient groups, patients who have received endovascular therapy should be carefully documented in register-based studies.  相似文献

On 21 November 2014, the 50th anniversary of the solemn promulgation of Lumen Gentium and Unitatis Redintegratio was celebrated. Between ‘aggiornamento’ and ‘ressourcement’ the Catholic Church had been striving to understand itself and its Tradition more precisely, in order to be newly relevant, lastingly true and authoritative in the future ? an indispensible task, if the gospel were to be proclaimed to the contemporary world, but not an easy one. It is little wonder that this completion of the Council's endeavours was preceded by its so-called ‘black week’. Questions remain as to the outcome of it all, and the articles assembled in this issue assess the reception of these two conciliar texts after 50 years. Where do the achievements lie? Where are the shortcomings? Where do questions need to be asked today that reach beyond the horizon of Vatican II?  相似文献

In this digital era, traditional recruitment efforts have increasingly been supplemented with or replaced by recruiting applicants on the Web. Concurrently, organizations are increasingly adapting to younger individuals from the Millennial generation as they enter the workforce. We combine these salient issues to examine Web-based recruitment of the Millennial generation by assessing predictors of organizational attraction. Using a sample of Millennials (N = 493), we found that perceptions of both work–life balance and website usability incrementally predicted attraction, when controlling for perceptions of other organization characteristics. In addition, person–organization fit mediated these relationships. These findings speak to the importance of examining how aspects of Web-based recruitment influence Millennial applicants.  相似文献

There has been a proliferation of new measures of individual differences in emotional processing, but too little research that evaluates the distinctiveness and utility of such measures. We critically evaluated the Level of Emotional Awareness Scale (LEAS), which is a measure of people's awareness of emotions in both the self and others. Across two studies, university students (N=124 and 107 for study 1 and 2, respectively) completed the LEAS, as well as a battery of personality measures and ability tests, and a mood-induction task. The LEAS was statistically distinct from a wide variety of personality measures, emotional intelligence tests, and self-report ability measures. In addition, both studies demonstrated that people high in emotional awareness were less likely than others to show mood congruent biases in their judgments (e.g. when bad moods lead to negative judgments and good moods to good judgments). The LEAS appears to be both distinctive and useful in understanding mood-relevant processes.  相似文献
