The present study examined the relationship of prenatal cocaine exposure to infant information processing in the first year of life.In a prospective, longitudinal study of 177 cocaine-exposed and 175 non-exposed infants, the Fagan Test of Infant Intelligence (FTII) was used to measure attention, visual recognition memory and information processing speed at 6.5 and 12 months of age. Groups were compared over time using mixed linear model analyses.Prenatal cocaine exposure predicted poorer visual recognition memory at 12 months, with exposed infants obtaining lower mean scores and a higher percentage of scores in the risk range. Across exposure groups, information processing speed increased with age, demonstrating a developmental effect. Tobacco and marijuana exposures were related to faster looking times, which did not relate to visual recognition memory.Cognitive deficits and attentional problems noted in prior studies of cocaine-exposed children at later ages may be detectable in infancy. 相似文献

Using two visual priming experiments, the present study investigates whether presenting facilitative semantic (i.e. colour) and morphosyntactic (i.e. grammatical gender) information in a prime image prior to reading a target sentence facilitates naming of a sentence-final target image among L1 German and L1 English-L2 German speakers. In Experiment 1, L1 and L2 German speakers used both semantic and gender cues to predict the sentence-final target image. In Experiment 2, a new group of L2 German speakers used gender cues to predict, but this effect was stronger when gender information was provided via a gender-marked indefinite article and adjective in the prime, than when the prime contained only the gender-marked article. These results suggest that if L2 speakers are able to overcome unstable and often inaccurate L2 gender assignment, they can use gender cues in a native-like manner for prediction, but that multiple gender-marked cues may be necessary for such prediction to occur. 相似文献

Understanding a joke relies on semantic, mnemonic, inferential, and emotional contributions from multiple brain areas. Anatomically
constrained magnetoencephalography (aMEG) combining high-density whole-head MEG with anatomical magnetic resonance imaging
allowed us to estimate where the humor-specific brain activations occur and to understand their temporal sequence. Punch lines provided either funny,
not funny (semantically congruent), or nonsensical (incongruent) replies to joke questions. Healthy subjects rated them as
being funny or not funny. As expected, incongruous endings evoke the largest N400m in left-dominant temporo-prefrontal areas,
due to integration difficulty. In contrast, funny punch lines evoke the smallest N400m during this initial lexical–semantic
stage, consistent with their primed “surface congruity” with the setup question. In line with its sensitivity to ambiguity,
the anteromedial prefrontal cortex may contribute to the subsequent “second take” processing, which, for jokes, presumably
reflects detection of a clever “twist” contained in the funny punch lines. Joke-selective activity simultaneously emerges
in the right prefrontal cortex, which may lead an extended bilateral temporo-frontal network in establishing the distant unexpected
creative coherence between the punch line and the setup. This progression from an initially promising but misleading integration
from left frontotemporal associations, to medial prefrontal ambiguity evaluation and right prefrontal reprocessing, may reflect
the essential tension and resolution underlying humor. 相似文献

This study examined the relationship between cognitive ability, personality, and academic achievement in post-secondary students, using latent variable models. Testing both simple and complex relationships, we found that cognitive ability and personality predicted reading achievement independently, but that they interact when predicting math achievement - at least in the Conscientiousness and Openness to Experience domains. 相似文献

Previous studies reveal age by valence interactions in attention and memory, such that older adults focus relatively more on positive and relatively less on negative stimuli than younger adults. In the current study, eyeblink startle response was used to measure differences in emotional reactivity to images that were equally arousing to both age groups. Viewing positive and negative pictures from the International Affective Picture System had opposite effects on startle modulation for older and younger adults. Younger adults showed the typical startle blink pattern, with potentiated startle when viewing negative pictures compared to positive pictures. Older adults, on the other hand, showed the opposite pattern, with potentiated startle when viewing positive pictures compared to viewing negative and neutral pictures. Potential underlying mechanisms for this interaction are evaluated. This pattern suggests that, compared with younger adults, older adults are more likely to spontaneously suppress responses to negative stimuli and process positive stimuli more deeply. 相似文献

A large body of research has documented the performance-debilitating effects of stereotype threat for individuals, but there is a paucity of research exploring interpersonal consequences of stereotype threat. Two experiments tested the hypothesis that stereotype threat would change the style in which women communicate. Results indicate that women who experience stereotype threat regarding leadership abilities react against the stereotype by adopting a more masculine communication style. Study 2 provides evidence that self-affirmation eliminates this effect of stereotype threat on women's communication styles. A third study demonstrates an ironic consequence of this effect of stereotype threat on women's communication--when women under stereotype threat adopt a more masculine communication style, they are rated as less warm and likeable, and evaluators indicate less willingness to comply with their requests. Theoretical and practical implications of these findings are discussed. 相似文献

We examined the effects of baseline training sequence on the emergence of conditional discriminations in an intraverbal naming task. Thirty‐two college students were randomly assigned to two groups. The tact‐intraverbal (TI) group first learned to vocally tact eight visual stimuli using a unique verbal label for each stimulus, and then to intraverbally relate four pairs of verbal labels. The intraverbal‐tact (IT) group received the same training but in the opposite sequence. Both groups then received a match‐to‐sample test involving the visual stimuli alone. On average, the TI group had significantly shorter reaction times than the IT group throughout all four test blocks, even when controlling for intraverbal retention, which was lower in the IT group. Accuracy on the MTS test did not differ significantly between groups when controlling for intraverbal retention. However, MTS accuracy and intraverbal retention were strongly correlated in the IT group but uncorrelated in the TI group. We suggest the effect of training sequence reflects different sources of stimulus control available to subjects in different groups when confronted with the novel MTS trials. 相似文献

We assessed the factor structure of the DAPP-BQ (Livesley & Jackson, in press), as well as the relations between DAPP-BQ higher- and lower-order personality trait scores and DSM-IV (APA, 2000) personality disorder symptoms in a sample of approximately 300 nonclinical young adults. The four-factor structure of the DAPP-BQ was replicated, and DAPP-BQ higher-order and lower-order scores were related to personality disorder symptoms in predictable ways. Finally, regression analyses revealed that specific DAPP-BQ traits accounted for variance in individual personality disorder scores above and beyond comorbid personality disorder symptoms. 相似文献
