Typically developing children have been shown to imitate the specific means used by an adult to achieve an object‐directed outcome, even if a more efficient method is available. It has been argued that this behaviour can be attributed to social and communicative motivations. The purpose of this study was to investigate whether children with autism spectrum disorders (ASD), relative to children with Down syndrome (DS), show a reduced tendency to copy the exact means used by an adult to produce a novel outcome. To achieve this a sample of 34 children (22 with ASD and 12 with DS) were given a test of object‐directed imitation. Contrary to expectation, children in both groups imitated the specific method of the model to the same high extent. This finding is in line with suggestions that object‐directed imitation is relatively spared in children with autism but is surprising given arguments linking such imitation to socially based motivations. Nevertheless, children's ability to successfully copy the model was associated with their communicative ability, providing some support for the link between imitation and communication.  相似文献

Information-processing theories posit that persons who have experienced trauma may have disturbed emotional processing and therefore exhibit an excess of negative responses to otherwise neutral cues. The role of this mechanism in traumatized children has yet to be fully investigated. This study examined the relationship of varied clinical characteristics and theoretically relevant moderating variables to increased trauma related responding on a non-idiographic sentence completion task. One hundred and eighty-nine children (ages 6–17) residing at a residential home between 1996 and 2011 who had experienced physical, emotional and/or sexual abuse were administered a sentence completion task and the Trauma Symptom Checklist for Children (TSCC) shortly after their admission. Three independent raters determined whether sentence completion responses were trauma related (TRR), non-trauma related, or ambiguous. Trauma related responses were then reviewed for either avoidant/denial style responding or loss related responding. The TSCC posttraumatic stress subscale (PTS) was the only subscale that was uniquely related to TRR. A significant interaction between abuse type and PTS was found with sexual abuse moderating the effect of PTS on TRR. Additionally, age at assessment was positively correlated with both TRR and loss related responding. Time since removal from home was negatively correlated with TRR. Gender differences were found for TRR and loss related responding. These findings highlight the empirical relevance of the sentence completion task in clinical research. Results are discussed in terms of their implications for research, assessment, and intervention.  相似文献

The accuracy of judgmental forecasts of temperature and precipitation was analyzed. In contrast to the findings of many studies of expert judgment and forecasting, forecasts were highly accurate and forecaster agreement was high. Human forecasters performed better than an operational forecasting model and about the same as a linear regression model. Differences between temperature and precipitation forecasts could be predicted from differences between the tasks. In general, differences between tasks were much greater than differences between forecasters. Task predictability was an excellent indicator of forecast accuracy. The characteristics of the environment for forecasting temperature and precipitation that contribute to accuracy include high-quality information and the availability of "guidance" based on a computer model. It is concluded that an understanding of the properties of the task is essential for understanding the accuracy of expert judgment.  相似文献

The encoding of temporal order information improves with practice (Zacks, Hasher, Alba, Sanft, & Rose, 1984), but this improvement may be a result of task performance factors and may have little or nothing to do with encoding phenomena. In the present study, a forced-choice recency discrimination procedure was used to obviate the use of retrieval/performance strategies on the temporal order test. No improvement in temporal order judgments was observed.  相似文献

Unitary‐resource models posit a collective attentional resource responsible for sustaining information processing across all modalities. In contrast, multiple‐resource models presume a system of modality‐independent resources. The two models predict similar within‐modal performance, but seemingly contradictory cross‐modal performance. Discordant outcomes in past research are here hypothesized to result from inconsistent levels of cognitive load imposed within experimental tasks. Participants monitored two simultaneously presented alphabetic letter arrays consisting of the serial presentation of a target and multiple distractors. The dual‐task design required the identification of targets in within‐modal and cross‐modal trials. Cognitive load was manipulated by altering the presentation rate of the letters. While cross‐modal performance was generally superior and cognitive load was associated with decreasing performance, the cross‐modal advantage prominent at low levels of cognitive load was absent under high cognitive load. Therefore, neither resource model can alone account for dual‐task processing, suggesting the role of a hierarchical resource model. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

Complex problem solving is often an integration of perceptual processing and deliberate planning. But what balances these two processes, and how do novices differ from experts? We investigate the interplay between these two in the game of SET. This article investigates how people combine bottom‐up visual processes and top‐down planning to succeed in this game. Using combinatorial and mixed‐effect regression analysis of eye‐movement protocols and a cognitive model of a human player, we show that SET players deploy both bottom‐up and top‐down processes in parallel to accomplish the same task. The combination of competition and cooperation of both types of processes is a major factor of success in the game. Finally, we explore strategies players use during the game. Our findings suggest that within‐trial strategy shifts can occur without the need of explicit meta‐cognitive control, but rather implicitly as a result of evolving memory activations.  相似文献

Three experiments are presented to examine the role of discrimination abilities in the relationship between confidence and performance across items that vary in difficulty. The studies also test the confidence-frequency effect, predicted in the theory of probabilistic mental models (Gigerenzer, Hoffrage, & Kleinbolting, 1991), by investigating the relationship between performance estimates provided as confidence judgments and as estimates of the frequency of correct responding. The categorical judgment task involved predicting whether a handwriting sample, generated using naturalistic sampling, had been written by a female or male. The results suggest that, when outcome variability is taken into account, discrimination ability differs drastically between easy, medium, and hard items. Discriminability is greatest for easy items and decreases until it disappears for hard items. There was also evidence of a confidence-frequency effect, with mean confidence judgments showing a slight tendency toward overconfidence and frequency estimates showing a slight tendency to underestimate performance.  相似文献

An experiment was conducted with American college students to determine whether differences in cultural perspectives might act as an impediment to empathic responding. Participants read about targets who experienced distress in a social context and who assumed a perspective that was consistent or inconsistent with norms typical of U.S. culture. When evaluating targets with a dissimilar as opposed to similar cultural perspective, participants exhibited a lack of perspective taking, perceiving those responses as inappropriate, atypical, and dissimilar to their own likely response in that situation. They also tended to attribute dissimilar targets' distress to dispositional as opposed to situational forces, essentially assigning them more blame. Further, emotional empathy, including feelings of compassion and sympathy were lessened with respect to targets whose responses reflected unfamiliar cultural norms. Path analyses indicated that inadequate appreciation of the different cultural perspective could account for much of the reduction in empathic concern. Results suggest that lack of perspective taking with regard to divergent cultural norms may compromise cross‐cultural exchanges of tolerance and compassion.  相似文献

The decision whether to explore new alternatives or to choose from familiar ones is implicit in many of our daily activities. How is this decision made? When will deviation from optimal exploration be observed? The current paper examines exploration decisions in the context of a multi‐alternative “decisions from experience” task. In each trial, participants could choose a familiar option (the status quo) or a new alternative (risky exploration). The observed exploration rates were more sensitive to the frequent outcome from choosing new alternatives than to the average outcome. That is, the implicit decision whether to explore a new alternative reflects underweighting of rare events: Over‐exploration was documented in “Rare Disasters” environments, and insufficient exploration was evident in “Rare Treasures” environments. In addition, the results reveal a decrease in exploration of new alternatives over time even when it is always optimal and some exploration even when it is never reinforcing. These results can be captured with models that share a distinction between “data collection” and “outcome‐driven” decision modes. Under the data collection mode, the decision maker collects information about the environment, to be used in future choices. Under the outcome‐driven mode, the decision maker relies on small samples of previous experiences with familiar versus unfamiliar alternatives, before the selection of a specific alternative. The predictive value of a two‐parameter “explorative sampler” quantification of these assumptions is demonstrated. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

In the first year of life, the ability to search for hidden objects is an indicator of object permanence and, when multiple locations are involved, executive function (i.e. inhibition, cognitive flexibility and working memory). The current study was designed to examine attentional predictors of search in 5‐month‐old infants (as measured by the looking A‐not‐B task), and whether levels of maternal education moderated the effect of the predictors. Specifically, in a separate task, the infants were shown a unique puppet, and we measured the percentage of time attending to the puppet, as well as the length of the longest look (i.e., peak fixation) directed towards the puppet. Across the entire sample (N = 390), the percentage of time attending to the puppet was positively related to performance on the visual A‐not‐B task. However, for infants whose mothers had not completed college, having a shorter peak looking time (after controlling for percentage of time) was also a predictor of visual A‐not‐B performance. The role of attention, peak fixation and maternal education in visual search is discussed. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

The present study investigated processes of social judgment from the perspective of a minority group. Black participants evaluated either Black or White law‐school applicants who possessed either strong or weak credentials. Consistent with predictions of the shifting‐standards model (Biernat, Manis, & Nelson, 1991), a significant pattern of out‐group polarization emerged when judgments were made on subjective, but not objective response scales. Importantly, results revealed that out‐group polarization on subjective response scales was moderated by participants' stereotypes. In line with shifting‐standards predictions, only participants who viewed Blacks relatively favorably, compared to Whites, on the dimension of school performance showed a significant pattern of out‐group polarization. The shifting‐standards model is discussed in relation to other judgment models.  相似文献

It is widely accepted in psychology and cognitive science that there are two “systems” in the mind: one system (System 1) is characterized as quick, intuitive, perceptive, and perhaps more primitive, while the other (System 2) is described as slower, more deliberative, and responsible for our higher‐order cognition. I use the term “reflectivism” to capture the view that conscious reflection—in the “System 2” sense—is a necessary feature of good moral judgment and decision‐making. This is not to suggest that System 2 must operate alone in forming our moral decisions, but that it plays a normatively ineliminable role. In this paper, I discuss arguments that have been offered in defense of reflectivism. These arguments fit into two broad categories; let us think of them as two sides of a coin. On the first side are arguments about the efficaciousness of conscious reasoning—for example, without conscious deliberation we will make bad moral judgments and decisions. On the other side of the coin are arguments about the centrality of conscious deliberation to normative actions—for example, without conscious deliberation we are no more agential than animals or automatons. Despite their attractiveness, I argue that these arguments do not successfully establish that reflection is a necessary component of good moral judgment and decision‐making. If I am right, the idea that good moral judgment and decision‐making can result from entirely automatic and subconscious processes gains traction. My goal in this paper is to show that reflectivism fails to include the full range of cases of moral decision‐making and that a theory of automaticity may do a better job. I briefly discuss at the end of the paper how an account of successful automatic moral judgment and decision‐making might begin to take shape.  相似文献

This study investigates the effect of off‐task breaks, where individuals engage in a collective off‐task activity, on group creativity. Using an experimental method comprising 36 groups of 5 individuals, the relationships between different types of off‐task group break and performance in creative tasks post‐break are explored. When compared to the no‐break case, it is seen that off‐task breaks, in which all individuals participate in the group activity, lead to more original ideas being generated post‐break. On the other hand, individual incubation breaks and self‐organizing group breaks, lead to lower levels of post‐break idea originality when compared with the no‐break case. This research thus highlights the positive benefits of off‐task breaks involving full member participation, on the creative process in groups.  相似文献

This study examined participants' perceptions of the cues they believed to be important when making intelligence judgments in zero‐acquaintance contexts. In total, 467 British participants rated 29 items for how important they were when making judgments of intelligence and completed scales measuring their personality, self‐assessed intelligence, and demographics. A factor analysis showed that the 29 intelligence cues could be reduced to 4 factors: Physical Cues, Nonphysical Cues, Adornments, and Knowledge. There were no gender differences in ratings of these factors, and Knowledge was rated as the most important factor, followed by Nonphysical Cues, Adornments, and Physical Cues. These factors were weakly associated with participants' personality scores and self‐assessed intelligence. Results are discussed in relation to the literature on intelligence judgments.  相似文献

This study provides new evidence concerning task specificity in creativity—examining through a cross‐cultural perspective the extent to which performance in graphic versus verbal creativity tasks (domain specificity) and in divergent versus convergent creativity tasks (process specificity) are correlated. The relations between different creativity tasks in monocultural and multicultural samples of Chinese and French children were compared. Electronic versions of the Wallach and Kogan Creativity Test (WKCT , W allach & K ogan, 1965; L au & C heung, 2010) and the Evaluation of Potential Creativity (EP oC; L ubart, B esançon, & B arbot, 2011; B arbot, B esançon, & L ubart, 2011) were used. Both measures showed satisfactory psychometric properties and cross‐cultural structural validity. The results showed that culture has an impact on the structure of creative ability: It appeared that correlation patterns were different across Chinese and French groups and across monocultural and multicultural groups. Such results show that it is crucial to take task specificity into account when investigating the effect of culture on creativity. Indeed, our study implies that cultural differences that are found using one specific creativity task might not be automatically generalizable to all sorts of creativity tasks. Limitations are discussed and perspectives for future research on culture and task specificity in creativity are proposed.  相似文献

Evaluation judgments were affected by information order and not by subsequent unconscious versus conscious deliberation. In three experiments, we examined the influence of early positive information on final evaluations of four objects. Based on a task analysis, we predicted primacy effects in judgments in a sequential data acquisition task. Thinking periods following presentation were used to manipulate conscious or unconscious processing. In all three studies, we found no effects of thinking manipulations but instead found reliable order effects. We developed and tested an online judgment model on the basis of the belief updating model of Hogarth and Einhorn. The model accounted for large proportion of the individual level variability, and model comparison tests supported the presence of a primacy effect. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
