When personal control is threatened, people often turn to their own group and show negativity towards others. In three studies, we tested an alternative prediction that the salient lack of personal control (vs. control) experienced in the context of unemployment can lead to connectedness and more positive perception of similar others (e.g., members of groups affected by unemployment or the economic crisis). In two European countries, we found experimental (Study 1: Poland) and correlational (Study 2: Spain) evidence that a lowered sense of control of unemployed people was related to more favorable intergroup evaluations. Furthermore, when lack of control related to unemployment threat was experimentally induced, participants perceived a Greek outgroup more positively, and this effect was mediated by identification with and similarity to this group (Study 3). We discuss the role of the shared experience of collective uncontrollability in promoting positive intergroup relations.  相似文献

Expressing anger can engender desired change, but it can also backfire. In the present research we examined how power shapes the expression of anger. In Study 1, we found that powerless individuals were less inclined to express their anger directly but more inclined to express it indirectly by sharing it with others. Powerless participants’ reluctance to express anger directly was mediated by negative social appraisals. In Study 2, we replicated the effect of power on direct anger expression in a situation in which participants had actual power (or not). Anger was evoked in the laboratory using an ecologically valid procedure, and participants were given an opportunity to express anger. Study 3 showed that powerless participants expected direct anger expression to arouse more anger than fear in the target, whereas the opposite was true for indirect anger expression. Powerful participants always expected to elicit more fear than anger in the target.  相似文献

We described a 56-years-old man with a diagnosis of "non-fluent primary progressive aphasia" (NfPPA). An accurate neuropsychological, neurological and neuroimaging evaluation was performed in order to assess clinical and behavioural features of the patient. From a neuropsychological point of view, the patient showed a typical cognitive profile of subjects affected by NfPPA: a prominent language deficit, associated with impairments in several cognitive domains after three years from the onset of the symptomatology. The most intriguing feature is that SPECT revealed hypoperfusion in the right frontal cortex, albeit the patient is right-handed. This unexpected finding shows that NfPPA may arise not only from cortical abnormalities in the language-dominant left hemisphere, but also from right hemisphere involvement in a right hander (crossed aphasia).  相似文献

This study is a validation of the Spanish version of the Social Phobia and Anxiety Inventory using a nonclinical sample (198 participants) and a clinical sample (72 participants with social phobia). The factor structure and concurrent validity with Fear of Negative Evaluation and Social Avoidance and Distress scales were analyzed. The Social Phobia and Anxiety Inventory demonstrated good concurrent validity, showing statistically significant relationships with Fear of Negative Evaluation and Social Avoidance and Distress. Results confirmed the rationale for the division of the SPAI into two subscales. Results also demonstrated the utility of the Social Phobia and Anxiety Inventory for differentiating between a nonclinical sample and participants with a social phobia, and its adequate reliability.  相似文献

The present study examines the efficacy of a program designed to enhance college students'learning processes and study strategies. The program was organised around a number of letters written by a freshman, Gervásio (Rosário, Nú?ez, & González-Pienda, 2006), telling about his new experiences, troubles, and successes in the university. This intervention program is intended to promote a series of strategies (cognitive, meta-cognitive, and supportive) which allow students to manage their learning processes in a more proficient, successful, and autonomous way. The collected data suggest that students who had the opportunity to follow the program significantly improved their declarative knowledge about learning strategies, reduced their use of surface approaches to study, and extended the newly acquired skills to new and different tasks and assignments.  相似文献

There is a paucity of studies aimed at comparing how parents and children in different family structures cope with the challenges posed by the adolescence transition; in particular, there are few studies aimed at comparing adoptive and foster families. In order to partially fill this gap, the principal aims of the present study were to verify whether there are differences in parent–child communication among foster, intercountry adoptive, and biological families according to the adolescents' gender, and to compare the perceptions of parents and adolescents concerning parent–child communication. Data were elaborated on two levels: a generational level (adolescent's and his/her parents' perceptions among the three family groups) and a dyadic level (mother–child and father–child perceptions). The sample was composed of 276 Italian families with adolescents aged between 11 and 17 (81 foster, 98 international adoptive, and 97 biological families). Subjects (mothers, fathers, and children) filled out a questionnaire including the Parent–Adolescent Communication Scale (Barnes & Olson, 1985 ). Results highlighted that in foster families, parent–child communication showed more difficulties from both the adolescent's and the parents' point of view. Adoptive adolescents, however, reported a more positive communication with both their parents than did their peers living in biological and foster families. At a dyadic level, some differences emerged among the three groups. In biological families, a more pronounced distance emerged between parents and children. In adoptive families, father and adolescent shared more similar perceptions, whereas a significant discrepancy emerged between mother and child. A higher level of perceptual congruence between adolescents and parents was found in foster families. Gender differences were also seen: Mothers experienced a more open communication with their children than did fathers, and adolescents, and above all females, communicated better with their mothers than with their fathers in all three family groups.  相似文献

Mexico-U.S. migration creates situations that may cause psychological distress. The purpose of this research project was to study the impact of father's physical absence due to international migration (FPAIM) on adolescent offspring of rural immigrants from Zacatecas, Mexico. Stressors and compensators were studied from the adolescent's perspective and were analyzed using a stress-mediator-consequences theoretical framework. Qualitative (n = 24) and quantitative (n = 310) methodologies were used with a nonrandom sample of adolescents. Results show that the FPAIM is an ambivalent experience for adolescents that has positive and negative elements. Though migrants' children seem to be more vulnerable to psychosocial stress than are the offspring of nonmigrants, gender, not father's absence, appears to be the most important risk factor for psychological distress.  相似文献

The four experiments reported in this paper were designed to determine to what extent words are lexically represented in terms of their morphological structure. The experiments are carried out in Spanish, a language with rich morphological resources, using a priming paradigm and a lexical decision task. In particular, they examined the pattern of priming effects in regular inflected words with gender and in derived words, in comparison to those produced by orthographically and semantically related words, by manipulating form similarity and semantic transparency. The results showed, on the one hand, that regular inflected words produced reliable facilitatory effects which are not driven just by form relatedness (Experiments 1 and 2). On the other hand, they showed that both transparent and nontransparent derived forms produced facilitatory effects distinct from purely orthographic and semantic effects (Experiments 3 and 4.). In general, these findings suggest that morphological information is represented in the mental lexicon and may play a central role in the individuation and retrieval of lexical entries.  相似文献

A fMRI study of word retrieval in aphasia   总被引:9,自引:0,他引:9  
The neural mechanisms underlying recovery of cognitive functions are incompletely understood. Aim of this study was to assess, using functional magnetic resonance (fMRI), the pattern of brain activity during covert word retrieval to letter and semantic cues in five aphasic patients after stroke, in order to assess the modifications of brain function which may be related to recovery. Four out of five patients had undergone language recovery, according to standard testing, after at least 6 months of rehabilitation. The cerebral activation of each patient was evaluated and compared with the activation pattern of normal controls studied with the same fMRI paradigm. In the patients, the pattern of brain activation was influenced by the site and extent of the lesion, by the degree of recovery of language, as reflected by task performance outside the scanner, and by task requirements. In the case of word retrieval to letter cues, a good performance was directly related to the activation in Broca's area, or in the right-sided homologue. On the other hand, in the case of semantic fluency, the relationship between performance level and activation was less clear-cut, because of extensive recruitment of frontal areas in patients with defective performance. These findings suggest that the performance in letter fluency is dependent on the integrity of the left inferior frontal cortex, with the participation of the homologous right hemispheric region when the left inferior frontal cortex is entirely of partially damaged. Semantic fluency, which engages the distributed network of semantic memory, is also associated with more extensive patterns of cerebral activation, which however appear to reflect retrieval effort rather than retrieval success.  相似文献
