The study examined correlations between incidental learning of foreign words and interhemispheric connectivity, operationalized
as consistency of hand preference, using pooled data of five experiments on adult foreign language learning (N=242). Inconsistent hand preference was found to be positively correlated with vocabulary learning even after effects of cognitive
variables (verbal working memory capacity and nonverbal IQ), identified previously as predictive of successful foreign-language
vocabulary learning, were partialled out. This observed relationship between handedness consistency and vocabulary learning
persisted when left-handed and right-handed individuals were analyzed separately, and there was no overall difference in performance
between left- and right-handers. The findings confirm an association between degree of handedness and verbal episodic memory. 相似文献

The objective of the present study was to examine the effects of aggression and conflict-managing skills on popularity and attitude to school in Russian adolescents. Three types of aggression (physical, verbal, and indirect), constructive conflict resolution, third-party intervention, withdrawal, and victimization were examined using the Peer-Estimated Conflict Behavior (PECOBE) inventory [Bjorkquist and Osterman, 1998]. Also, all respondents rated peer and self-popularity with same-sex classmates and personal attitude to school. The sample consisted of 212 Russian adolescents (101 boys, 111 girls) aged between 11 and 15 years. The findings attest to significant sex differences in aggression and conflict resolution patterns. Boys scored higher on physical and verbal aggression, and girls on indirect aggression. Girls were socially more skillful than boys in the use of peaceful means of conflict resolution (they scored higher on constructive conflict resolution and third-party intervention). The attributional discrepancy index (ADI) scores were negative for all three types of aggression in both sexes. Verbal aggression is apparently more condemned in boys than in girls. ADI scores were positive for constructive conflict resolution and third-party intervention in both genders, being higher in boys. In girls, verbal aggression was positively correlated with popularity. In both sexes, popularity showed a positive correlation with constructive conflict resolution and third-party intervention, and a negative correlation with withdrawal and victimization. Boys who liked school were popular with same-sex peers and scored higher on constructive conflict resolution. Girls who liked school were less aggressive according to peer rating. They also rated higher on conflict resolution and third-party intervention. Physical aggression was related to age. The results are discussed in a cross-cultural perspective. 相似文献

Four studies test both the alternative explanation advanced by Hoorens and Todorova (1988) for Nuttin's (1984, 1985, 1987) name letter effect (NLE), and two interpretations for an unexplained finding of the former authors. Flemish, Hungarian and Thai children show an increasing rather than a decreasing NLE over primary school grades (studies 1, 2 and 4). Thai university students and school children prefer own name letters in their ‘mother’ alphabet (Thai) but also in their second (Roman) alphabet (studies 3 and 4). All these results contradict the primacy of own name writing or mastery pleasure hypothesis. Independently of the time interval between the acquisition of both alphabets, a stronger NLE is found in the subjects ‘mother’ alphabet than in their second alphabet, contradicting a mitigated mastery pleasure explanation for the stronger NLE in one's ‘mother’ alphabet (Hoorens and Todorova, 1988). All the data are consistent with Nuttin's interpretation of the NLE in terms of the affective consequences of ‘mere ownership’. Finally, the striking generality of the NLE over languages, alphabets, and cultures is again demonstrated. 相似文献

This study examined which body part labels children could (i) produce when the experimenter touched different locations on her own body, asking each time ‘What's this?’ and (ii) comprehend by touching the correct locations on their own bodies in response to the experimenter asking ‘Where's the [body‐part label]?’. Seventeen children aged between 26 and 41 months, tested in a repeated measures procedure, were presented with 50 different body part stimuli in 200 test trials per child. Overall, the children produced fewer body part labels than they could comprehend. The accuracy of children's responses depended on (i) the location or extent of each body part (facial and broad body features were better known; joints and features in or attached to broad body parts the least well known); (ii) the amount of sensory (but not motor) representation each body part has in the human cortex; and (iii) whether a body part was commonly named by caregivers. These results present a precise mapping of the body parts that young children are able to name and locate on their own bodies in response to body part names; they suggest several possible determinants of lexical‐semantic body knowledge and add to the understanding of how it develops in childhood. 相似文献

In the Mozambican socio-cultural context, men’s extramarital sexual relationships are generally deemed acceptable, and women are “recommended” to forgive their husbands’ sexual infidelity. Thus, the purpose of this study was to assess to what extent Mozambican women would forgive their husbands in case of an extramarital sexual relationship. The material consisted of 24 vignettes—each of which contained the story of a husband who was having an extramarital sexual relationship—a question, and an 11-point response scale. Overall, 225 women indicated their willingness to forgive their husbands in case of sexual infidelity, as a function of three factors: the emotional intensity involved in the extramarital sexual relationship, the regret expressed by the husband, and the commitment involved in the relationship/marriage between the husband and his wife. ANOVA results showed that the willingness to forgive depends on the nature of the extramarital relationship and the attitude of the “cheater”: (a) in the case where the extramarital relationship was of a purely sexual type, without involving deep emotions, and when the husband expressed profound regret, the willingness to forgive was high; (b) in the opposite situation, i.e., when the extramarital relationship involved a high level of emotions, and the husband expressed no regret, the forgiveness was low. Older participants had relatively high rates of forgiveness compared to younger ones. These findings corroborate earlier studies showing that, for females, emotional infidelity was much more distressful than purely sexual infidelity, and corroborate studies showing that Mozambicans tend to forgive offenders when they express regret. 相似文献

Excitation of the mesocorticolimbic pathway, originating from dopaminergic neurons in the ventral tegmental area (VTA), may be important for the development of exaggerated fear responding. Among the forebrain regions innervated by this pathway, the amygdala is an essential component of the neural circuitry of conditioned fear. The functional role of the dopaminergic pathway connecting the VTA to the basolateral amygdala (BLA) in fear and anxiety has received little attention. In vivo microdialysis was performed to measure dopamine levels in the BLA of Wistar rats that received the dopamine D(2) agonist quinpirole (1 μg/0.2 μl) into the VTA and were subjected to a fear conditioning test using a light as the conditioned stimulus (CS). The effects of intra-BLA injections of the D(1) antagonist SCH 23390 (1 and 2 μg/0.2 μl) and D(2) antagonist sulpiride (1 and 2 μg/0.2 μl) on fear-potentiated startle (FPS) to a light-CS were also assessed. Locomotor performance was evaluated by use of open-field and rotarod tests. Freezing and increased dopamine levels in the BLA in response to the CS were both inhibited by intra-VTA quinpirole. Whereas intra-BLA SCH 23390 did not affect FPS, intra-BLA sulpiride (2 μg) inhibited FPS. Sulpiride's ability to decrease FPS cannot be attributed to nonspecific effects because this drug did not affect motor performance. These findings indicate that the dopamine D(2) receptor pathway connecting the ventral tegmental area and the basolateral amygdala modulates fear and anxiety and may be a novel pharmacological target for the treatment of anxiety. 相似文献

A novel method to measure oxidative stress resulting from exhaustive exercise in rats is presented. In this new procedure we evaluated the erythrocyte antioxidant enzymes, catalase (CAT) and glutathione reductase (GR), the plasma oxidative attack markers, reactive carbonyl derivatives (RCD) and thiobarbituric reactive substances (TBARS). Muscular tissue damage was evaluated by monitoring plasma creatine kinase (CK) and plasma taurine (Tau) concentrations. Also, we monitored total sulphydryl groups (TSG) and uric acid (UA), and the level of the 70 kDa heat shock protein (HSP70) in leukocytes as a marker of oxidative stress. In the study we found a correspondence between erythrocyte CAT and GR activities and leukocyte HSP70 levels, principally 3 h after the acute exercise, and this suggested an integrated mechanism of antioxidant defense. The increase in levels of plasma Tau was coincident with the increasing plasma levels of CK and TBARS, principally after two hours of exercise. Thus tissue damage occurred before the expression of any anti-oxidant system markers and the monitoring of Tau, CK or TBARS may be important for the estimation of oxidative stress during exhaustive exercise. Furthermore, the integrated analyses could be of value in a clinical setting to quantify the extent of oxidative stress risk and reduce the need to perform muscle biopsies as a tool of clinical evaluation. 相似文献
