In this study, the authors investigated the relation between early social contingency experiences and infants' competencies to detect nonsocial contingencies. In this study of 87 three-month-old infants, the authors operationalized early social contingencies as prompt, contingent maternal responses and coded microanalytically on the basis of video-recorded mother-infant interactions. The authors assessed competence to detect nonsocial contingencies by 2 methods: (a) the mobile conjugate reinforcement paradigm, which focuses on detecting contingencies between the infants' actions (kicking) and nonsocial consequences (mobile moving) and (b) the visual expectation paradigm, which focuses on detecting contingencies between 1 event (a smiley face projected on a screen) that was followed by a 2nd event (a complex picture projected on the other side of the screen). The results showed that early social contingencies are related to the competency to detect nonsocial action-consequence contingencies in the mobile conjugate reinforcement paradigm. 相似文献

Young children are assumed to be inefficient inhibitors in a number of cognitive tasks. In two experiments, we examined whether such deficits extend to children's episodic recall. We used two inhibition paradigms: retrieval-induced forgetting, the detrimental effect of retrieval practice with a subset of learned items on recall of the unpracticed items, and part-list cuing, the detrimental effect of the presentation of a subset of learned items on recall of the remaining items. In both experiments, the inhibitory effects were compared across three age groups: first or second graders, fourth graders, and young adults. The two children groups showed the same amounts of retrieval-induced forgetting and part-list cuing as the adult group, pointing to intact retrieval inhibition in young children's episodic recall. These results parallel very recent results on older adults' episodic recall, suggesting that both retrieval-induced forgetting and part-list cuing develop early in life and remain intact for the greater part of the lifespan. 相似文献

In a dual-task paradigm, a visual-encoding task with a deferred verbal report of a moving target was combined with a speeded task, in which participants prepared a precued leftward or rightward key-press response that was withheld until an auditory go signal. We manipulated the interval between the response cue and the target for the visual-encoding task, the interval between this target and the go signal, and spatial cross-task compatibility between the direction of the target movement in the visual task and the speeded manual response. The results of two experiments suggest that visual encoding interferes with response preparation and with the initiation of the prepared manual response at a short target-go interval. Also, responses were faster in compatible than in incompatible trials, indicating a cross-task compatibility effect. Experiment 2 reversed this compatibility effect by instruction, suggesting that the compatibility effect is based on response-response overlap. In both experiments, response preparation impaired accuracy in the visual task. Taken together, these results suggest that response processes and visual encoding share common codes and processes. 相似文献

This article proposes to analyse some aspects of the appropriation of New School thinking in Brazil, particularly Deweyan pragmatism, in the 1950s and 1960s. The analysis is based on the assumption that the developmentalist ideology that punctuated the debate on the economic, political and social restructuring of the country in these two decades constituted fertile ground for the return and expansion of pragmatist thinking amongst Brazilian educators, articulating itself, sometimes in contradictory ways, with this ideology. The focus of the analysis will be on the writings of the group of educators which circulated around the figure of Anísio Teixeira, at the time director of the National Institute for Pedagogic Studies (INEP), an organ linked to the Ministry of Education and Culture (MEC), which set itself the task of producing research that would support public policy in the field of education, as well as constituting itself as a center for teacher education and the stimulus and development of innovative experiences in the public school system. The appropriation of Deweyan pragmatism, in this context, had a triple perspective: pragmatism as scientific method, implying a specific conception of science, particularly the social sciences, with emphasis on the application of scientific knowledge in the solution of practical problems; as a way of democratic life; and as a synonym for experimentalism, in the sphere of schooling. 相似文献

There is overwhelming evidence that during speech planning semantically related words become lexically activated and compete for selection with the to-be-produced target word. The vast majority of this evidence stems from studies using the picture-word task, in which a distractor word (e.g., bird) drawn from the same semantic category as the target (e.g., fish) was shown to inhibit the picture-naming response more strongly than did an unrelated distractor word. By contrast, corresponding evidence from distractor words (e.g., carp) bearing a hierarchical relation to the target (e.g., fish) is sparse and inconclusive. In the present study, we investigated effects of subordinate-level distractors during basic-level naming and effects of basic-level distractors during subordinate-level naming. Hierarchically related distractors were found to inhibit the naming response in both situations. This pattern of results did not depend on whether the pictures were preferably named at the basic level or at the subordinate level. The results suggest that hierarchically related name alternatives compete for selection. 相似文献

Inhibition of abandoned tasks in task switching can be inferred when a worse performance is found withn− 2 task repetitions (ABA sequences) than with nonrepetitions (CBA sequences). Recent evidence has shown that this inhibition
effect decreases with long intertrial intervals (i.e., response-cue intervals, RCIs). Two alternatives have been proposed
to account for this decrease. One alternative attributes the observed decrease to the decay of inhibition itself. The other
alternative proposes that decay of the activation of competing tasks reduces the interference and leads to less inhibition.
To decide between these alternatives, we manipulated RCI trialwise. The results favor the decay-of-activation account as an
explanation for the decreased inhibition effect. This links the amount of inhibition to the activation level of the competing
tasks, whereas evidence for the decay of inhibition remains weak. 相似文献

A study of distance estimations between German cities investigated the organization of mental maps and their specific deviations
from reality. Potential factors for the deviation of mental maps from reality are physical barriers, emotional involvement,
and semantic unity. Distance estimations between cities situated in different former parts of Germany (East or West) were
systematically overestimated compared to distances of cities located in the same parts of Germany. This trend was strengthened
when participants had a negative attitude toward the reunification of Germany. The impact of these results is far reaching,
because overestimated distances between both German parts indicate that there still exists a mental gap between East and West—even
in young people—15 years after the German reunification. 相似文献

Familiarized names are falsely judgedfamous more often than nonfamiliarized names. Banaji and Greenwald (1995) demonstrated a gender bias in thisfalse fame effect, with the effect being larger for male than for female names. This effect was interpreted as reflecting the operation of
a gender stereotype. However, the famous male names were, in fact, better known than the famous female names. Thus, the presence
of more famous male names during study may have contributed to the observed male-famous association. If so, there should be
no gender bias if the studied famous male and female names are equally famous, and a reversed gender bias should emerge if
the famous female names are more famous than the male names. In two experiments, these predictions were corroborated. A “classical”
gender bias was found only when the famous males were more famous than the famous females. These findings are consistent with
the hypothesis that the gender bias in fame judgments, rather than showing implicit gender stereotyping in the sense of a
transsituational judgment bias, reflects the fact that, in test, participants select a proportion of fame judgments to male
and female names so that it matches the relative degree of fame of male and female names encountered during study. 相似文献
