Young children's reasoning about the order of past events 总被引:2,自引:0,他引:2
Four studies are reported that employed an object location task to assess temporal-causal reasoning. In Experiments 1-3, successfully locating the object required a retrospective consideration of the order in which two events had occurred. In Experiment 1, 5- but not 4-year-olds were successful; 4-year-olds also failed to perform at above-chance levels in modified versions of the task in Experiments 2 and 3. However, in Experiment 4, 3-year-olds were successful when they were able to see the object being placed first in one location and then in the other, rather than having to consider retrospectively the sequence in which two events had happened. The results suggest that reasoning about the causal significance of the temporal order of events may not be fully developed before 5 years. 相似文献

Cooperative problem solving has gained a lot of attention over the past two decades, but the range of species studied is still small. This limits the possibility of understanding the evolution of the socio-cognitive underpinnings of cooperation. Lutrinae show significant variations in socio-ecology, but their cognitive abilities are not well studied. In the first experimental study of otter social cognition, we presented two species—giant otters and Asian small-clawed otters—with a cooperative problem-solving task. The loose string task requires two individuals to simultaneously pull on either end of a rope in order to access food. This task has been used with a larger number of species (for the most part primates and birds) and thus allows for wider cross-species comparison. We found no differences in performance between species. Both giant otters and Asian small-clawed otters were able to solve the task successfully when the coordination requirements were minimal. However, when the temporal coordination demands were increased, performance decreased either due to a lack of understanding of the role of a partner or due to difficulty inhibiting action. In conclusion, two species of otters show some ability to cooperate, quite similar to most other species presented with the same task. However, to draw further conclusions and more nuanced comparisons between the two otter species, further studies with varied methodologies will be necessary. 相似文献

The emotional Stroop task is a widely used method for investigating attentional bias towards stimuli due to mood or affect. In general, standardized stimuli are used, which might not be appropriate when investigating individual contextual frameworks. It was investigated whether words chosen to be related to individuals' personal life events would produce more pronounced Stroop interference (as an indicator of attentional bias) than stimuli without any personal relevance. Twenty-six nonclinical subjects, 20 female and 6 male, participated in the study. Mean age was 36.1 yr. (SD = 18.1). All were recruited by means of local advertising. Stimulus material consisted of four word types: personal words related to negative life events with and without current personal relevance, and negative and neutral words without any personal relevance. Words were presented in three blocks. Analysis of variance showed main effects for word type and blocks, with slower reactions in the personally relevant conditions than in the negative, or neutral conditions, and in response to the first blocks as opposed to the last. These findings indicate that regardless of the word valence, personally relevant stimuli evoke more pronounced Stroop interference than do stimuli without personal relevance. 相似文献

Two visual-world eyetracking experiments were conducted to investigate whether, how, and when syntactic and semantic constraints are integrated and used to predict properties of subsequent input. Experiment 1 contrasted auditory German constructions such as, The hare-nominative eats ... (the cabbage-acc) versus The hare-accusative eats ... (the fox-nom), presented with a picture containing a hare, fox, cabbage, and distractor. We found that the probabilities of the eye movements to the cabbage and fox before the onset of NP2 were modulated by the case-marking of NP1, indicating that the case-marking (syntactic) information and verbs' semantic constraints are integrated rapidly enough to predict the most plausible NP2 in the scene. Using English versions of the same stimuli in active/passive voice (Experiment 2), we replicated the same effect, but at a slightly earlier position in the sentence. We discuss the discrepancies in the two Germanic languages in terms of the ease of integrating information across, or within, constituents. 相似文献

Contemporary theoretical accounts of perceptual learning typically assume that observers are either unbiased or stably biased
across the course of learning. However, standard methods for estimating thresholds, as they are typically used, do not allow
this assumption to be tested. We present an approach that allows for this test specific to perceptual learning for contrast
detection. We show that reliable decreases in detection thresholds and increases in hit rates are not uniformly accompanied
by reliable increases in sensitivity (d′), but are regularly accompanied by reliable liberal shifts in response criteria (c). In addition, we estimate the extent to which sensitivity could have increased in the absence of these liberal shifts. The
results pose a challenge to the assumption that perceptual learning has limited or no impact on response criteria. 相似文献

The goal of the research reported in this article was to examine whether social categorization, commonly thought to be a function of accessibility and intra‐category fit, is also sensitive to changes in inter‐category fit. Intra‐category fit refers to the match between a target person's features and stored categorical knowledge, inter‐category fit to the extent to which category memberships and targets' features covary across perceived group members. In Experiments 1, 2, and 3, members of social categories of low, medium, and high accessibility, respectively, were shown in a group discussion. Inter‐category fit was manipulated in three steps. Category salience in memory increased as an additive function of accessibility and inter‐category fit. Experiment 4 replicated the effects of inter‐category fit while intra‐category fit and the information presented for individual discussants were held constant. The present studies are the first to demonstrate an effect of inter‐category fit on a relatively direct measure of spontaneous social categorization. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

This contribution discusses some problems of Pragma-Dialectics and explains them by its consensualistic view of the function
of argumentation and by its philosophical underpinnings. It is suggested that these problems can be overcome by relying on
a better epistemology and on an epistemological theory of argumentation. On the one hand Pragma-Dialectics takes unqualified
consensus as the aim of argumentation, which is problematic, (Sect. 2) on the other it includes strong epistemological and rationalistic elements (Sect. 3). The problematic philosophical underpinnings of Pragma-Dialectics, specifically Critical Rationalism as well as Logical
Constructivism and Dialogic Logic of the Erlangen School, are among the sources of this incoherence (Sect. 4). A detailed critique of the Pragma-Dialectical discussion rules shows the negative consequences of this foundation and indicates
how they could be avoided (Sects. 5, 6). 相似文献

The present paper investigated whether academic psychologists show a tendency to rate the quality and appropriateness of scientific
studies more favorably when results and conclusions are consistent with their own prior beliefs (i.e., confirmation bias).
In an online experiment, 711 psychologists completed a questionnaire (e.g., about their belief in astrology) and evaluated
research that was presented in form of a short abstract in which 40 different behaviors (e.g., alcohol consumption, willingness
to share money) have been tried to be predicted. The research to be evaluated varied on three dimensions which were all manipulated
between subjects: (1) the predictors of the 40 behaviors (either Big Five or astrological factors), (2) the methodological
quality of the study (low, medium, high), and (3) the results and subsequent conclusion of the study (confirmation or disconfirmation
of the hypotheses). Factor-analyzed scores of participants’ ratings on 8 scales, resulting in 2 factors termed quality and
appropriateness, served as dependent measures. The main result of the study is a two-way interaction: Psychologists tended
to evaluate results qualitatively higher when they conformed to their own prior expectations, as in this case, when astrological
hypotheses were disconfirmed. 相似文献
