We investigated whether adult learners' knowledge of phonotactic restrictions on word forms from their first language impacts their ability to use statistical information to segment words in a novel language. Adults were exposed to a speech stream where English phonotactics and phoneme co-occurrence information conflicted. A control where these did not conflict was also run. Participants chose between words defined by novel statistics and words that are phonotactically possible in English, but had much lower phoneme contingencies. Control participants selected words defined by statistics while experimental participants did not. This result held up with increases in exposure and when segmentation was aided by telling participants a word prior to exposure. It was not the case that participants simply preferred English-sounding words, however, when the stimuli contained very short pauses, participants were able to learn the novel words despite the fact that they violated English phonotactics. Results suggest that prior linguistic knowledge can interfere with learners' abilities to segment words from running speech using purely statistical cues at initial exposure. 相似文献

A nonverbal false belief task was administered to children (mean age 5 years) and two great ape species: chimpanzees (Pan troglodytes) and bonobos (Pan paniscus). Because apes typically perform poorly in cooperative contexts, our task was competitive. Two versions were run: in both, a human competitor witnessed an experimenter hide a reward in one of two containers. When the competitor then left the room (version A) or turned around (version B), the experimenter switched the locations of the containers. The competitor returned and reached with effort, but unsuccessfully, towards the incorrect container. Children displayed an understanding of the competitor's false belief by correctly choosing the other container to find the reward. Apes did not. However, in version A (but not version B), apes looked more often at the unchosen container in false belief trials than in true belief control trials, possibly indicating some implicit or uncertain understanding that needs to be investigated further. 相似文献

This study investigates how flashbulb memories (FBMs) relative to the death of Pope John Paul II vary according to the persons' evaluation of the event's importance and consequences. In particular, FBMs were investigated in persons who were expected to attribute different degrees of importance/consequentiality to the event as a function of two factors: (1) religious involvement, (2) nationality (Polish, Italian, Swiss). The comparison was made with respect to the following hypothesized determinants of FBMs: surprise, emotional reaction, rehearsal, event memory and especially the attitudes towards the Pope and the appraisal of the importance and the consequences of his death. Structural equation modelling indicates that importance/consequentiality is a fundamental determinant of FBM and is influenced by antecedent personal and social characteristics reflected in the person's attitudes. Moreover, memory consistency seems to be both directly influenced by emotional intensity and indirectly through rehearsal, whereas surprise seems not a critical determinant of FBM.

The paper describes the development of the Portuguese version of the Students’ Life Satisfaction Scale and the examination
of its psychometric properties. A sample of 367 Portuguese students completed the Students’ Life Satisfaction Scale (SLSS;
Huebner in Sch Psychol Int 12:231–240, 1991a), Children’s Hope Scale (CHS; Synder in J Pediatr Psychol 22:399–421, 1997),
Global Self-Worth Sub-scale (Harter, S. (1985). Manual for the self-perception profile for children. Denver: University of Denver) and Mental Health Inventory-5 (MHI-5; Berwick et al. in Medical Care 29:169–176, 1991). The
first step includes translation, back-translation, inspection for lexical equivalence and content validity, and cognitive
debriefing. Then we considered reliability, factor structure, and criterion-related validity. The validation process of the
Portuguese SLSS version shows psychometric properties similar to the English language SLSS, suggesting that it measures the
same construct in the same way. Implications of these findings are discussed. 相似文献

A randomized between-group design was used to evaluate the efficacy of a video intervention to reduce post-traumatic stress disorder (PTSD) and other mental health problems, implemented prior to the forensic medical examination conducted within 72 h post-sexual assault. Participants were 140 female victims of sexual assault (68 video/72 nonvideo) aged 15 years or older. Assessments were targeted for 6 weeks (Time 1) and 6 months (Time 2) post-assault. At Time 1, the intervention was associated with lower scores on measures of PTSD and depression among women with a prior rape history relative to scores among women with a prior rape history in the standard care condition. At Time 2, depression scores were also lower among those with a prior rape history who were in the video relative to the standard care condition. Small effects indicating higher PTSD and Beck Anxiety Inventory (BAI) scores among women without a prior rape history in the video condition were observed at Time 1. Accelerated longitudinal growth curve analysis indicated a videoxprior rape history interaction for PTSD, yielding four patterns of symptom trajectory over time. Women with a prior rape history in the video condition generally maintained the lowest level of symptoms. 相似文献

The purpose of the present study was to test the hypothesis that environmental factors affect the magnitude of gender differences in spatial performance only when the tasks used are susceptible to the influence of such factors. Two hundred and ninety White middle-class undergraduate students (165 females, 125 males) completed the Vandenberg and Kuse Mental Rotations Test (MRT), a paper and pencil version of the Water Level Task (WLT), and toys and sports preference questionnaires. Results revealed that males outperformed females on both spatial tests. In addition, a main effect of toys preference showed that participants with a spatial toys preference outperformed those with a nonspatial preference on both the MRT and the WLT. This main effect was qualified by an interaction between this factor and gender. The interaction was found only on the WLT and showed that gender differences were only significant in participants with a nonspatial preference. An interaction of sports preference and gender was also observed. This interaction revealed that, in contrast to what was obtained with toys, gender differences on both spatial tests were significant only in participants with a spatial sports preference. Implications of these findings with regard to the development of gender differences in spatial abilities are discussed. 相似文献

The literature reports mixed results on the imagery abilities of the blind, at times showing a difference between sighted and blind individuals and at other times similarities. However, the possibility that the results are due to different strategies spontaneously used in performing the imagery tasks has never been systematically studied. A large group of 30 totally congenitally blind (TCB) individuals and a group of 30 sighted individuals matched for gender age and schooling were presented with a mental pathway task on a complex two-dimensional (5 × 5) matrix. After administering the task, participants were interviewed in order to establish the strategy they used. Results showed that both sighted and TCB may use a spatial mental imagery, a verbal or a mixed strategy in carrying out the task. Differences between the groups emerged only when last location and then entire pathway had to be remembered rather than just the last position, and were clearly affected by the type of strategy. Specifically, TCB performed more poorly than the sighted individuals when they used a spatial mental imagery strategy, whereas the two groups had a similar performance with a verbal strategy. 相似文献
