Participants studied AB word pairs and completed three recognition tests. In one recognition test each A word was presented with two distractors that did not appear on the study list. In another recognition test each B word was presented with two distractors that did not appear on the study list. In a third recognition test an AB target was presented with two distractors composed of words not on the study list. Six different groups of participants each performed the recognition tests in a different order, so that all possible orders were tested. Recognition of the A, B, and AB targets for a given study pair were independent of each other when single-word recognition preceded double-word recognition. There was almost complete independence in the reverse order. Even when recognition judgements were restricted to those for which the participants were most confident, there was independence of recognition among the three tests. A pair recognition test served as an additional study trial for the individual words; however, the reverse was not the case. All of these results were predicted by a single three-parameter mathematical model derived from the hypothesis that single-word and double-word targets had independent representations in memory. 相似文献
The phonological similarity effect (PSE) was studied in two tasks of serial recall, in one task of serial recognition and one item identification task. PSE occurred only in the former three tasks involving memory of order when study items were words and nonwords with an associative connectedness to long-term memory. Nonwords that, according to a reaction time assessment of associative value, were less well connected to long-term memory mechanisms, were not sensitive to phonological similarity. These results are discussed in relation to contemporary models of short-term memory that explain the PSE as a result of confusions of items that are similarly encoded in a phonological layer. This layer is identified as a higher-level phonological space that is accessed by words and nonwords of high associative value and not by nonwords of low associative value. 相似文献
Low family socioeconomic status (SES) is linked with adolescents’ symptoms of depression, but little is known about the mediating and moderating mechanisms underlying this association. Based on ecosystem theory and the organism-environment interaction model, we tested whether emotional resilience mediated the relationship between family SES and depressive symptoms, and whether parent–child relationship quality moderated the relationship. Adolescents (N?=?724) from one middle school in central China completed self-reported questionnaires regarding demographic variables, family SES, emotional resilience, parent–child relationship quality, and depressive symptoms. Regression-based mediation analysis indicated that emotional resilience mediated the association between family SES and depressive symptoms. Parent–child relationship quality moderated two components of this mediation process, namely the effects of low SES on both emotional resilience and depressive symptoms. In both cases, a high quality parent–child relationship ameliorated the adverse effects of low family SES. That is, adolescents with a higher quality relationship with their parent appeared to be less affected by low family SES. The study reveals how and when family SES may affect adolescents’ depressive symptoms, and highlights the protective effect of a high quality parent–child relationship in a low SES environment.
Smartphones are important communication and technological tools that have become an indispensable part of university students’ lives. Although empirical research has evaluated factors that influence Smartphone addiction, few studies have explored positive and potentially protective factors such as virtues that may increase the efficacy of future Smartphone addiction prevention programs. Thus, this study examined the relationship between three key virtues (i.e., relationship, vitality, and conscientiousness) and Smartphone addiction as well as evaluated the specific contributions of these virtues as applied to Smartphone use among Chinese university students. A total of 682 undergraduates (aged 18–24 years) from three universities completed the 96-item Chinese Virtues Questionnaire and Mobile Phone Addiction Index. Results showed that three virtues were significantly correlated with Smartphone addiction. Specifically, conscientiousness and relationship virtues negatively predicted Smartphone addiction and explained 82.61% of addiction-related variance. Vitality positively predicted Smartphone addiction and accounted for the remaining 17.39% variance. Thus, this study demonstrated that conscientiousness and relationship virtues were potential protective factors for Smartphone addiction, while vitality led to increased vulnerability. Gender-related differences were also discovered. Specifically, male students may be more sensitive to the conscientiousness virtue, while female students may show increased sensitivity to the relationship virtue. Consequently, future efforts to prevent Smartphone addiction could focus on how to enhance conscientiousness and relationship virtues and how to reduce the vitality virtue. 相似文献
