In three experiments, we studied the influence of foreign language knowledge on native language performance in an exclusively native language context. Trilinguals with Dutch as their native and dominant language (L1), English as their second language (L2), and French as their third language (L3) performed a word association task (Experiment 1) or a lexical decision task (Experiments 2 and 3) in L1. The L1 stimulus words were cognates with their translations in English, cognates with their translations in French, or were noncognates. In Experiments 1 and 2 with trilinguals who were highly proficient in English and relatively low in proficiency in French, we observed shorter word association and lexical decision times to the L1 words that were cognates with English than to the noncognates. In these relatively low-proficiency French speakers, response times (RTs) for the L1 words that were cognates with French did not differ from those for the noncognates. In Experiment 3, we tested Dutch-English- French trilinguals with a higher level of fluency in French (i.e., equally fluent in English and in French). We now observed faster responses on the L1 words that were cognates with French than on the noncognates. Lexical decision times to the cognates with English were also shorter than those to the noncognates. The results indicate that words presented in the dominant language, to naive participants, activate information in the nontarget, and weaker, language in parallel, implying that the multilinguals’ processing system is profoundly nonselective with respect to language. A minimal level of nontarget language fluency seems to be required, however, before any weaker language effects become noticeable in L1 processing.  相似文献

Recent research has shown that children remember more from television news than from print news, a finding that has been explained by the extra mnemonic support offered by redundant television pictures (the dual‐coding hypothesis). The present study was designed to examine three alternative explanations, which attribute children's superior recall of television news to (a) underutilization of the print medium, (b) a recall advantage of listening compared with reading, and imperfect reading ability. A sample of 192 fourth and sixth graders was presented with children's news stories, either in (a) their original television form, (b) a bare print version, a print version supplemented with photo material or in (d) an audio version. Results indicated that the television presentation was remembered better than any of the other three versions. The results of the study were consistent with the dual‐coding hypothesis, whereas no support was found for the alternative explanations tested in the study.  相似文献

Abstract— M. Del Giudice and J. Belsky (this issue) suggest that males and females tend to follow different reproductive strategies associated with different types of insecure attachments. It is clear that gender differences in reproductive strategies and in close relationships may exist. However, there is no support for gender differences in attachment behaviors and representations in the current evidence base. The authors propose to consider attachment and close relationships as horses of different colors and to examine their potentially gendered association as independently assessed constructs.  相似文献

The current study examines attachment‐style differences in responses to inductions of group respect and disrespect. Participants completed a scale assessing attachment anxiety and avoidance, performed group tasks, and received high, average, or low respect feedback from group members. Then we assessed commitment to this group, actual effort expenditure on behalf of the group, and money donation to the group. For participants scoring relatively high on attachment anxiety, high group respect heightened group commitment and effort expenditure on behalf of the group, whereas group disrespect led to lower group commitment but to more money donation to the group and higher effort expenditure. Participants who scored relatively low on attachment anxiety were not significantly affected by group respect or disrespect. The implications of attachment theory for group dynamics were discussed.

The predictive value of different infant attachment measures was examined in a community‐based sample of 111 healthy children (59 boys, 52 girls). Two procedures to assess infant attachment, the Attachment Q‐Set (applied on a relatively short observation period) and a shortened version of the Strange Situation Procedure (SSSP), were applied to the children at age 15 months and related to a comprehensive set of indicators of the children's socioemotional development at age 5 years. Three attachment measures were used as predictors: AQS security, SSSP security, and SSSP attachment disorganization. AQS security and SSSP security jointly predicted the security of the children's attachment representation at age 5. Apart from that, SSSP attachment disorganization was a better predictor of the children's later socioemotional development than were the other two early attachment measures. First, attachment disorganization was the only attachment measure to predict the children's later ego‐resiliency, school adjustment, and dissociation. Second, as for the socioemotional measures at age 5 that also were related to AQS or SSSP security (i.e., peer social competence and externalizing problems), the attachment security measures did not explain any extra variance beyond what was explained by attachment disorganization.  相似文献

Three experiments were conducted to examine the relative ability of the cerebral hemispheres to identify capital letters traced in the palms of the hands. In Experiment 1, letters were presented either right side up or upside down, and the subject's task was to name the letter aloud or point to an identical letter using the stimulated hand. Analysis of the accuracy data revealed that the left palm/right hemisphere (LP/RH) performed this task significantly better than did the right palm/left hemisphere (RP/LH), particularly when the stimuli were presented in the upside-down orientation. In Experiments 2 and 3, subjects performed the same letter identification task; however, on half the trials, they were required to maintain either a spatial or verbal concurrent memory load (i.e., a 24-point Vanderplas & Garvin form or six low-imagery nouns, respectively). In the no-load condition of Experiment 2 (spatial forms), the previously observed LP/RH advantage was replicated. However, in the load condition, this LP/RH superiority was no longer in evidence. In Experiment 3 (low-imagery nouns), the presence of a concurrent verbal task had minimal impact on the previously observed performance asymmetry as the LP/RH advantage was obtained in both the no-load and load conditions. The results of the three studies taken in composite suggest that (1) the operations utilized to identify letters traced in the palms of the hands are primarily spatial in nature and (2) that the observed performance asymmetry may be attributed to a right hemisphere superiority for the analysis and codification of information along a spatial dimension. These findings are discussed in terms of a \"process-oriented\" model of hemispheric asymmetry.  相似文献

A school‐based life skills and sexuality education HIV/AIDS program for adolescents was evaluated in Toluca, Mexico, through a quasi‐experimental pre–post design with 1,566 cases, divided over a control group and an experimental group. Based on a previously tested path model, 3 levels of variables were included as a guide for the contents of the program: personal variables (self‐knowledge, self‐efficacy regarding condom use, and decision making), intervening variables (subjective norms about, knowledge about HIV/AIDS, and attitudes toward condoms), and outcome variables (communication on sexuality and intentions to use condoms). Evaluation was conducted following these categories. Significant increases in all of these variables recognized as precursors of safer sex were found in the experimental group.  相似文献

The study examines delinquent behavior and psychopathy and assesses their relationship to victim injury in a population of 168 incarcerated juvenile delinquent males with lengthy histories of criminal and violent behavior. A series of multiple regressions found that 17% of the variance associated with level of victim injury was accounted for by a model that included the three-factor model of the Psychopathy Checklist: Youth Version [Forth, Kosson, and Hare, 2003], criminal versatility, and age of onset of criminal offending. Notably, anger and DSM-IV symptoms of conduct disorder were not related to level of victim injury. The results of this study support an escalation hypothesis where individuals with earlier onset to criminal behavior and greater criminal versatility escalate to more severe violence. The current results demonstrate the importance of integrating established theories of juvenile delinquency when explaining severe violence in youth.  相似文献
