Recent studies of adults have found evidence for consolidation effects in the acquisition of novel words, but little is known about whether such effects are found developmentally. In two experiments, we familiarized children with novel nonwords (e.g., biscal) and tested their recognition and recall of these items. In Experiment 1, 7-year-olds were then retested on either the same day or the following day to examine changes in performance after a short delay compared with a longer delay that included sleep. Experiment 2 used two age groups (7- and 12-year-olds), with all participants being retested 24h later. The 12-year-olds accurately recognized the novel nonwords immediately after exposure, as did the 7-year-olds in Experiment 2 (but not in Experiment 1), suggesting generally good initial rates of learning. Experiment 1 revealed improved recognition of the novel nonwords after both short (3- to 4-h) and longer (24-h) delays. In contrast, recall was initially poor but showed improvements only when children were retested 24h later, not after a 3- to 4-h delay. Similar improvements were observed in both age groups despite better overall performance in 12-year-olds. We argue that children, like adults, exhibit offline consolidation effects on the formation of novel phonological representations. 相似文献

We examined whether the results of a response‐restriction analysis (RRA) could be predicted on the basis of response distribution in early sessions, when these sessions indicated interaction with multiple items. Four preschool‐aged children participated. For 3 of the 4 participants, the results from sessions conducted prior to restriction of the first item corresponded closely with results of the full RRA. 相似文献

This longitudinal study among ethnic migrants from Russia to Finland (N = 127) examined the relationships between anticipated and perceived discrimination, ethnic and national identities, and outgroup attitudes towards the national majority group. The study included one pre‐migration and two post‐migration assessments. First, associations between the variables studied were tested using a conventional autoregressive sample‐level modelling approach. Second, individual trajectories and the associations between the individual‐level changes in the variables included in the models were tested. Although there were no sample‐level effects over time, there were significant relationships between changes in discrimination and changes in identification and outgroup attitudes at the individual level. The results indicated that changes in perceived discrimination were not reflected in increased ethnic identification. However, participants who perceived higher levels of discrimination after migration than they anticipated before migration were, in the post‐migration stage, more likely to disidentify from and to increasingly show negative attitudes towards the national majority group. The study complements previous research by examining the identity and attitudinal reactions to perceived ethnic discrimination starting from the pre‐migration stage and highlights the value of incorporating both group and individual perspectives to the research on perceived discrimination.

A centre–surround attentional mechanism was proposed by Carr and Dagenbach (Journal of Experimental Psychology: Learning,
Memory, and Cognition 16: 341–350, 1990) to account for their observations of negative semantic priming from hard-to-perceive primes. Their mechanism cannot account
for the observation of negative semantic priming when primes are clearly visible. Three experiments (Ns = 30, 46, and 30) used a familiarity decision with names of famous people, preceded by a prime name with the same occupation
as the target or with a different occupation. Negative semantic priming was observed at a 150- or 200-ms SOA, with positive
priming at shorter (50-ms) and longer (1,000-ms) SOAs. In Experiment 3, we verified that the primes were easily recognisable in the priming task at an SOA that yielded negative semantic priming,
which cannot be predicted by the original centre–surround mechanism. A modified version is proposed that explains transiently
negative semantic priming by proposing that centre–surround inhibition is a normal, automatically invoked aspect of the semantic
processing of visually presented famous names. 相似文献

Whereas physiological studies indicate that illusory contours (ICs) are signaled in early visual areas at short latencies, behavioral studies are divided as to whether IC processing can proceed in a fast, automatic, bottom-up manner or whether it requires extensive top-down intracortical feedback or even awareness and cognition. Here, we employ a response priming paradigm to assess two measures of IC processing using identical stimuli: response priming by ICs, which can occur independently of visual awareness, and a measure of visual awareness of the ICs. In three experiments, participants responded to the orientation of illusory and real-contour targets preceded by illusory and real-contour primes at stimulus-onset asynchronies from 35 to 106 ms. Both illusory and real-contour targets were strongly primed by ICs, and this effect was independent of prime visibility. The effect was fully present in the fastest responses and cannot be explained by responses to stimulus features other than the ICs. Results indicate that ICs, regardless of whether they are consciously perceived, activate fast motor responses, indicating that they are processed without time-consuming intracortical feedback. We conclude that conflicting studies were based on qualitatively different measures of IC processing, some depending on visual awareness and others independent of it.

The author describes "higher" and "uniquely human" sociocognitive skills that he argues as being necessary for tool use. We propose that those skills could be based on simpler detection systems humans could share with other animal tool users. More specifically, we discuss the impact of object affordances on the understanding and the social learning of tool use. 相似文献

The present research intended first to confirm psychophysiological and cortical responses to valence- and arousal-manipulated stimuli and second to show how the BIS and BAS (Behavioural Inhibition and Activation System) personality characteristics correlated with these psychophysiological and cortical responses. Multiple measures were recorded, such as psychophysiological (skin conductance response, heart rate, and electromyography) and ERPs (event-related potentials) responses, during viewing IAPS figures, that varied in terms of pleasantness (appetitive vs. aversive) and arousing power (high vs. low intensity). Autonomic variables and two ERP positive deflections (P3 and LPP ERP effects) were found to be modulated by valence and arousal rating, with an increased response for high arousing and negative or positive stimuli in comparison with low arousing and neutral stimuli. Moreover, high BAS subjects were more responsive to positive than negative emotions, whereas high BIS subjects responded in greater measure to negative and arousing emotions. Findings were discussed in light of biphasic model of emotion comprehension. 相似文献

This study takes an interest in instructions and instructed actions in the context of manual skills. The analysis focuses
on a video recorded episode where a teacher demonstrates how to crochet chain stitches, requests a group of students to reproduce
her actions, and then repeatedly corrects the attempts of one of the students. The initial request, and the students’ responses
to it, could be seen as preliminary to the series of corrective sequences that come next: the request and the following attempts
make it possible for the teacher to launch instructional sequences specifically designed and addressed to the students who
need further guidance. In the interaction between the teacher and the novice student, the reasoned character of the instructed
actions is not explained so much as installed and tuned. The materiality of the project makes it possible for the two parties
to methodically and meticulously adjust their actions in accordance with each other, and towards the gradual realization of
the aimed-for results. In connection to this, a number of issues pertaining to the reproducibility and recognizability of
manual skills are raised: how instructions-in-interaction orient towards the progression of the skill rather than the interaction
itself; how attempts by and mistakes of the instructed party provide grounds for further instruction; and, consequently, how
instructions in the form of corrections build on the instructor’s continuous assessments of the instructed actions. 相似文献

The present study examined measurement invariance of trait anger with respect to age. In addition, age-related differences in latent variables (factor variances, factor covariances, and factor means) were investigated. A sample of 1216 participants, divided into six age groups, ranging from under 30 to over 70 years, was tested using the angry temperament and angry reaction scales from the State-Trait Anger Expression Inventory (STAXI; Spielberger, 1988). Results show that strong measurement invariance held across the six age groups. For both angry temperament and angry reaction, factor variances tended to decrease into middle age and then increase again into old age. Factor correlations decreased into old age, implying a differentiation of trait anger. Finally, regarding factor means, older adults showed less anger than younger adults, suggesting higher levels of self-regulation or less exposure to anger-provoking contexts in later life. 相似文献
