Continuity of father-rated temperament in Finnish children (n = 115) aged from 6 months (the IBQ) to 5.5 years (the CBQ) was explored within the theoretical framework developed by Rothbart. Father-rated activity level, smiling and laughter and distress to limitations showed significant differential homotypic and heterotypic continuity, while soothability, duration of orienting and fear showed significant differential heterotypic continuity. On the level of latent superconstructs, father-rated positive and negative infant affectivity accounted for 5.1, 22.7 and 10.0% of the variance in childhood extraversion, effortful control and negative affectivity, respectively. Inter-parental comparisons (n = 109 family units) revealed that father-rated continuity was similar to mother-rated continuity. These findings give empirical credence to Rothbart's theory and to father-rated temperamental continuity from infancy onwards. 相似文献

The earliest electrophysiological correlate of visual awareness? 总被引:2,自引:0,他引:2

To examine the neural correlates and timing of human visual awareness, we recorded event-related potentials (ERPs) in two experiments while the observers were detecting a grey dot that was presented near subjective threshold. ERPs were averaged for conscious detections of the stimulus (hits) and nondetections (misses) separately. Our results revealed that hits, as compared to misses, showed a negativity around 180-350 ms at occipital and posterior temporal sites. It was followed by a positive wave after 400-500 ms, peaking at parietal sites. These correlates were not affected by a manipulation of attention. The early negativity, called 'visual awareness negativity' (VAN), may be a general, primary electrophysiological correlate of visual awareness. The present data show that it can be observed in response to appearance of a stimulus in visual awareness and that it generalizes across different manipulations of stimulus visibility. 相似文献

Traditional models of face perception (e.g. Bruce and Young 1986) stress independent routes for processing identity and emotional expression. We investigated the interplay between familiarity and emotional expression by systematically varying both factors. In contrast to earlier studies which used binary forced-choice decisions, participants had to judge the familiarity of the presented face and the emotional hedonic valence and emotional arousal of its expressed emotion (angry, happy or neutral), using rating scales. The results demonstrated symmetric, strong interactions between familiarity and expressed emotion. Thus, this study supports more recent models of face perception (Haxby et al. 2000) that were mostly based on brain imaging data. These data together with our behavioural results emphasize the interaction of emotional expression and personal identity and support approaches that propose a relative segregation of these processes, rather than completely independent coding (Calder and Young 2005). 相似文献

Children in two age groups (7 vs. 12 yrs, N= 174) individually interacted with a stranger and were later interviewed about this event. Right before the interview, each child encountered the stranger once again and he engaged in a conversation where he either suggested that a (central or peripheral) detail originally present in the event had actually not been there or that an originally non-present (central or peripheral) detail had in fact been there. It was hypothesized that the two types of misinformation would result in omission and commission errors respectively. The results showed that the social influence resulted in an asymmetric effect (i.e., more commission than omission errors). Importantly, we also found that the children made more errors with respect to the peripheral detail (a suitcase), compared to the central detail (a passenger). Younger children did not make more errors (neither omission nor commission errors) than older children. 相似文献

The processing speed account suggests that general slowing of mental processing speed results in an overall decline, especially age-related decline, in other cognitive domains. Support for the speed account comes mainly from cross-sectional studies with participants that vary in age (age-heterogeneous samples). This study investigated how well variations in processing speed predict change of episodic recall in a longitudinal framework and examined with the Narrow Age Cohort (NAC) design. Data were obtained from Betula, a population-based longitudinal study. Both 5-year (n= 490; Time 3 - Time 4) and 10-year follow-up results (n= 608; Time 1 - Time 3) were used. In both samples, which were subjected to prospective dementia screening, we found considerably weaker associations in longitudinal data compared to cross-sectional, and also weaker associations in age-homogeneous than in age-heterogeneous samples. The results provide little support for the speed account. 相似文献

Cognitive and linguistic skills in Swedish children with cochlear implants - measures of accuracy and latency as indicators of development 总被引:1,自引:1,他引:0

The purpose of the present study was to examine working memory (WM) capacity, lexical access and phonological skills in 19 children with cochlear implants (CI) (5;7-13;4 years of age) attending grades 0-2, 4, 5 and 6 and to compare their performance with 56 children with normal hearing. Their performance was also studied in relation to demographic factors. The findings indicate that children with CI had visuospatial WM capacities equivalent to the comparison group. They had lower performance levels on most of the other cognitive tests. Significant differences between the groups were not found in all grades and a number of children with CI performed within 1 SD of the mean of their respective grade-matched comparison group on most of the cognitive measures. The differences between the groups were particularly prominent in tasks of phonological WM. The results are discussed with respect to the effects of cochlear implants on cognitive development. 相似文献

Much recent psycho- and neuro-linguistic work has aimed to elucidate the mechanisms by which sentence meanings are composed by investigating the processing of semantic mismatch. One controversial case for theories of semantic composition is expressions such as the clown jumped for ten minutes, in which the aspectual properties of a punctual verb clash with those of a durative modifier. Such sentences have been proposed to involve a coercion operation which shifts the punctual meaning of the verb to an iterative one. However, processing studies addressing this hypothesis have yielded mixed results. In this study, we tested four hypotheses of how aspectual mismatch is resolved with self-paced reading and magnetoencephalography. Using a set of verbs normed for punctuality, we identified an immediate behavioral cost of mismatch. The neural correlates of this processing were found to match effects in midline prefrontal regions previously implicated in the resolution of complement coercion. We also identified earlier effects in right-lateral frontal and temporal sites. We suggest that of the representational hypotheses currently in the literature, these data are most consistent with an account where aspectual mismatch initially involves the composition of an anomalous meaning that is later repaired via coercion. 相似文献

Deliberate self-harm was studied in 14-year-old adolescents from four schools in southern Sweden with a test-retest design, using a nine-item version of the Deliberate Self-Harm Inventory. At Time 1, 40.2% of the adolescents indicated deliberate self-harm on at least one occasion compared with 36.5% at Time 2. Test-retest data showed high stability over periods of up to 2 months in duration. Cross-validation of the results from Time 1 to Time 2 showed robust correlations between deliberate self-harm and general psychopathology, a relative absence of positive feelings toward parents, and a ruminative style of emotional regulation. Further, rumination/negative thinking and a relative absence of positive feelings toward parents were predictors of self-harm independently of general psychopathology. In addition, deliberate self-harm correlated with symptoms of eating disorder and negative body esteem in girls. 相似文献

Visual system has been proposed to be divided into two, the ventral and dorsal, processing streams. The ventral pathway is
thought to be involved in object identification whereas the dorsal pathway processes information regarding the spatial locations
of objects and the spatial relationships among objects. Several studies on working memory (WM) processing have further suggested
that there is a dissociable domain-dependent functional organization within the prefrontal cortex for processing of spatial
and nonspatial visual information. Also the auditory system is proposed to be organized into two domain-specific processing
streams, similar to that seen in the visual system. Recent studies on auditory WM have further suggested that maintenance
of nonspatial and spatial auditory information activates a distributed neural network including temporal, parietal, and frontal
regions but the magnitude of activation within these activated areas shows a different functional topography depending on
the type of information being maintained. The dorsal prefrontal cortex, specifically an area of the superior frontal sulcus
(SFS), has been shown to exhibit greater activity for spatial than for nonspatial auditory tasks. Conversely, ventral frontal
regions have been shown to be more recruited by nonspatial than by spatial auditory tasks. It has also been shown that the
magnitude of this dissociation is dependent on the cognitive operations required during WM processing. Moreover, there is
evidence that within the nonspatial domain in the ventral prefrontal cortex, there is an across-modality dissociation during
maintenance of visual and auditory information. Taken together, human neuroimaging results on both visual and auditory sensory
systems support the idea that the prefrontal cortex is organized according to the type of information being maintained in
WM. 相似文献

By referring to Niklas Luhmann’s theory of self-referential systems, Aldo Mascareño (2008, submitted for publication) gives an account of system-environment interrelatedness, explaining how social and individual constitute each other through the process of communication and co-creation of meanings. Two possible extensions to his account are discussed. Firstly, auto-communication within the system that happens without any external reference needs to be taken into account while describing the existence and constant re-creation of psychic systems. Secondly, in order for the system and environment or two systems to communicate, an imagined and temporary intersubjectivity between the two needs to be assumed. 相似文献
