Ruffman (2014) argues for a minimalist account of infants’ performance on theory of mind tasks. This commentary argues that because Ruffman’s minimalist account is post hoc, it neither generates testable predictions about how infants will respond in new situations, nor does it offer a coherent explanation for existing false-belief findings. An alternative, mentalist account is presented. This account integrates infancy findings with prior theory of mind literature and generates novel predictions about children’s false belief performance.  相似文献

Optimization versus response-strength accounts of behavior   总被引:6,自引:6,他引:0       下载免费PDF全文
Pigeons were run in both single-key and concurrent-key experiments in which, over most of the range of response rates, an increase in response rate gave rise to a continuous decrease in reinforcement rate. In spite of the fact that a low response rate would have produced a high reinforcement rate, all birds responded at relatively high rates, thus keeping reinforcement rates substantially below the maximum possible. In the concurrent-key experiment, in addition to responding at relatively high rates, the birds' ratios of responses approximately matched the corresponding ratios of obtained reinforcers. The results are inconsistent with most theories of optimal performance, which assume that organisms behave in ways that either maximize reinforcement value or minimize deviations from a free-behavior point. On the other hand, the results are consistent with the assumption that reinforcement strengthens the tendency to respond.  相似文献

Previous studies suggest that both reward anticipation and expected or experienced conflicts activate cognitive control. The present study investigated how these factors interact during conflict processing. In two experiments, participants performed a variant of the Stroop task, receiving performance-dependent monetary rewards in some blocks. In addition, we manipulated the level of conflict-triggered reactive and expectancy-driven proactive control: In Experiment 1, we compared the Stroop effect after previously congruent and incongruent trials to examine the conflict adaptation effect (reactive control). We found that the level of motivation did not interact with conflict adaptation. In Experiment 2, we varied the proportion of congruent and incongruent trials to manipulate conflict expectancy (proactive control). The data suggest the effects of motivation to be less pronounced under conditions of high conflict expectancy. We conclude that the interaction of motivation with cognitive determinants of control depends on whether these activate proactive or reactive control processes.  相似文献

The present study was designed to identify the motivational–cognitive profiles of students in Singapore secondary schools using cluster movement. Five distinct motivated strategies for learning (MSL) profiles based on a sample of 304 students were revealed: those with low levels of motivational beliefs and cognition but high anxiety (Poor MSL); high motivational beliefs and cognition but low anxiety (Good MSL); moderate high motivational beliefs, cognition and anxiety (Average MSL); high motivational beliefs, cognition and anxiety (High MSL); and low motivational beliefs, cognition and anxiety (Low MSL). Findings of this study also showed cluster movement across two time points, revealing the shifts in cluster membership in terms of motivational–cognitive profiles over time. Students in Good MSL demonstrated the most adaptive learning profile and achieved the highest grades than other clusters. Our findings contributed to practical underpinnings of educational research as well as provided meaningful insights to both researchers and practitioners.  相似文献

Two theories about the relationship between memory and decisions are examined. In an explanation-based model, the organization in memory of decision-relevant information determines decisions. In an availability model, the amount of information sampled from memory that supports competing decisions is crucial. In Experiment 1, subjects read evidence from a legal trial, made decisions, and provided free-recall data. Evidence presentation order was manipulated to produce differences in evidence coherence. When the prosecution evidence order was coherent, the subjects were more likely to choose guilty verdicts, and recall of prosecution evidence, relative to defense evidence, was greater. Thus, both evidence coherence and availability of information in memory could account for the basic findings. In Experiment 2, recall differences were eliminated as a function of evidence order. The results show that verdict effects favoring the more coherent prosecution evidence are obtained even when the relative amounts of prosecution and defense recall are equated across conditions.  相似文献

The purpose of this study was to test predictions of two recent theories of realism of confidence. Ecological approaches to realism of confidence in one's general knowledge (Gigerenzer et al. , 1991; Juslin, in press a ; Björkman, in press) predict good calibration or, in the case of poor cognitive adjustment, overconfidence, within the cognitive domain. The subjective distance theory of confidence in sensory discriminations (Björkman et al. , 1992) predicts a pervasive underconfidence bias for sensory discriminations. Empirical data are reported showing that: (a) Calibration for sensory judgments is considerably poorer than calibration for well adapted cognitive judgements, a difference that can be entirely traced to underconfidence in the sensory domain. (b) While an initial overconfidence bias in the cognitive domain is removed by outcome feedback, the bias observed in sensory discriminations is unaffected even by a prolonged feedback session. It is suggested that the nature of confidence in sensory discriminations is different from the nature of confidence in cognitive judgments.  相似文献

The relationship between perceived loss of control and passivity in social activities in a non-handicapped institutionalized elderly population was assessed. Perceived loss of control was assessed from three different types of expectancies: low action-outcome expectancies, high situation-outcome expectancies, and low efficacy expectancies. Passivity scores were reported by the staff. The effect of these three types of expectancies on passivity was analyzed in terms of motivation and volition, which were treated as mediating variables. Overall analysis of the structural equations, as well as partial hierarchical regression analyses, showed that efficacy expectancies were good predictors of passivity, but this was not the case for the action-outcome and situation-outcome expectancies. These results lend more support to a volitional rather than to a motivational interpretation of the effect of control on passivity. The implications of these results for intervention and for a differentiated conception of expectancies are discussed.  相似文献

The focus of the present research was to compare the memory-based processing and here-and-now accounts of situation model updating during reading. The authors conducted two experiments as a follow-up on work by R. A. Zwaan and C. J. Madden (2004), who disputed the conclusions of E. J. O'Brien, M. L. Rizzella, J. E. Albrecht, and J. G. Halleran (1998). The latter researchers found support for the memory-based processing view by showing that readers experienced reading difficulty on a sentence that was consistent with an updated model of the story's protagonist but was inconsistent with initially stated information about the protagonist. In contrast, Zwaan and Madden eliminated what they argued were confounds in the items used by O'Brien et al. and found support for the here-and-now view. In the present article, data from 2 experiments seem to eliminate weaknesses inherent in both previous authors' work. Although the present results are consistent with the here-and-now account, they do not completely discredit the memory-based processing view.  相似文献

Imaginal perspective switches are often considered to be difficult, because they call for additional cognitive transformations of object coordinates (transformation hypothesis). Recent research suggests that problems can also result from conflicts between incompatible sensorimotor and cognitive object location codes during response specification and selection (interference hypothesis). Three experiments tested contrasting predictions of both accounts. Volunteers had to point to unseen object locations after imagined self-rotations and self-translations. Results revealed larger pointing latencies and errors for rotations as compared to translations, and monotic latency and error increases for both tasks as a function of the disparity of object directions between real and imagined perspective. Provision of advance information about the to-be-imagined perspective left both effects unchanged. These results, together with those from a systematic error analysis, deliver clear support for an interference account of imaginal perspective switches in remembered surroundings.  相似文献

Holistic versus analytic process models: a reply   总被引:1,自引:0,他引:1  
Two classes of stimulus process models are considered in this reply to Dykes and Cooper. It is shown that analytic models which assume that stimuli are initially processed in terms of constituent dimensions do not account for large amounts of published data. It is also shown that the holistic-discriminability model that Dykes and Cooper reject is nonetheless consistent with their results and predicts all of the data for which their analytic model was constructed to account.  相似文献

In this paper we report on our attempts to fit the optimal data selection (ODS) model (Oaksford & Chater, 1994; Oaksford, Chater, & Larkin, 2000) to the selection task data reported in Feeney and Handley (2000) and Handley, Feeney, and Harper (2002). Although Oaksford (2002b) reports good fits to the data described in Feeney and Handley (2000), the model does not adequately capture the data described in Handley et al. (2002). Furthermore, across all six of the experiments modelled here, the ODS model does not predict participants' behaviour at the level of selection rates for individual cards. Finally, when people's probability estimates are used in the modelling exercise, the model adequately captures only 1 out of 18 conditions described in Handley et al. We discuss the implications of these results for models of the selection task and claim that they support deductive, rather than probabilistic, accounts of the task.  相似文献

Three experiments investigating the effects of cognitive and motivational factors on stereotype change are reported. Trait ratings in all three experiments showed there to be greater stereotype-change when stereotype-inconsistent information was dispersed across many group members than when it was concentrated in only a few. A sorting task (Experiment 1) indicated that, in the concentrated conditions the stereotype disconfirmers were more strongly isolated from the rest of the group than in the dispersed conditions. Free recall protocols (Experiment 2) showed greater memory for the target exemplars when subjects anticipated interaction with a group member than when no interaction was anticipated. The questions subject chose to ask target group exemplars were also influenced by anticlpated future interaction. Subjects chose more stereotype-inconsistent questions when interactian was anticipated than when no interaction was anticipated. Experment 3 showed the impact of stereotype-inconsistent information to be greater when expectancies for the stereotyped group are weaker A cued-recall task yielded evidence of spontaneous subtyping. All these studies support the subtyping model, even in the presence of cognitive and motivational factors that might be expected to impede stereotype change.  相似文献

Schunk (1983) found in his study with U.S. students that teachers' ability feedback (“You're good at this”) had a stronger motivational effect on students' learning than that focusing on effort (“You've been working hard”). The present experimental study examined such differential effects of attributional feedback on 386 elementary and high school Chinese students who were brought up in a culture where effort and endurance were strongly emphasized. Generally, the results with elementary students (Grade 4) replicated Schunk's findings. Mutual reinforcement effects also showed that effort and ability feedbacks combined led to the highest perceived effort expenditure.

Researchers of social networks commonly distinguish between “behavioral” and “cognitive” social structure. In a school context, for example, a teacher’s perceptions of student friendship ties, not necessarily actual friendship relations, may influence teacher behavior. Revisiting early work in the field of sociometry, this study assesses the level of agreement between teacher perceptions and student reports of within-classroom friendship ties. Using data from one middle school teacher and four classes of students, the study explores new ground by assessing agreement over time and across classroom social contexts, with the teacher-perceiver held constant. While the teacher’s perceptions and students’ reports were statistically similar, 11–29% of possible ties did not match. In particular, students reported significantly more reciprocated friendship ties than the teacher perceived. Interestingly, the observed level of agreement varied across classes and generally increased over time. This study further demonstrates that significant error can be introduced by conflating teacher perceptions and student reports. Findings reinforce the importance of treating behavioral and cognitive classroom friendship networks as distinct, and analyzing social structure data that are carefully aligned with the social process hypothesized.
