Despite the importance of face recognition in everyday life and frequent complaints about its failure, there is no comprehensive test battery for this ability. As a first step in constructing such a battery, we present 18 tasks aimed at measuring face perception, face learning, face recognition, and the recognition of facially expressed emotions. A sample of 153 healthy young adults completed all tasks. In general, reaction time measures showed high estimates of internal consistency; tasks focused on performance accuracy yielded reliabilities that were somewhat lower, yet high enough to support their use in a battery of face cognition measures. Some of the tasks allowed computation of established experimental effects in a within-subjects design, such as the part-whole effect. Most of these experimental effects were confirmed in our large sample, and valuable effect size estimates were obtained. However, in many cases these difference measures showed poor estimates of internal consistency. 相似文献
We apply the theoretical construct of bounded rationality to an investment game, allowing participants to invest their monetary endowment in riskless bonds and risky assets. In our experiment, we elicit aspiration levels from participants: one captures a subsistence threshold, the other a success threshold. Participants can be classified according to these aspirations and the corresponding investment behavior. We differentiate between potential and actual satisficing. By presupposing specific cardinal utility functions, we also relate the bounded rationality approach to the traditional rational choice model. 相似文献
On the basis of current emotion theories and functional and neurophysiological ties between the processing of conflicts and
errors on the one hand and errors and emotions on the other hand we predicted that conflicts between prepotent Go responses
and occasional NoGo trials in the Go/NoGo task would induce emotions. Skin conductance responses (SCRs), corrugator muscle
activity, and startle blink responses were measured in three experiments requiring speeded Go responses intermixed with NoGo
trials of different relative probability and in a choice reaction experiment serving as a control. NoGo trials affected several
of these emotion-sensitive indicators as SCRs and startle blinks were reduced whereas corrugator activity was prolonged as
compared to Go trials. From the pattern of findings we suggest that NoGo conflicts are not aversive. Instead, they appear
to be appraised as obstructive for the response goal and as less action relevant than Go trials. 相似文献
In four experiments on the identification of familiar faces we reassessed a robust performance pattern—namely, the temporal advantage for retrieving biographical facts as compared to recalling proper names, which has been interpreted as reflecting a serial ordering of the access to semantic and name information. Evidence for recent parallel accounts had been provided by Scanlan and Johnston (1997) who reported an advantage for name retrieval in children. Here we replicated the findings of Scanlan and Johnston but also showed that the naming advantage disappears, and performance is very similar to that of adults when stimuli and tasks are used that are familiar to children. Conversely, we also demonstrated an advantage for name retrieval in adults when highly unfamiliar semantic facts were associated with the faces. Together these findings suggest that there is no fundamental difference in the cognitive architectures of children and adults. The experiments indicate that the relative speed of naming and semantic fact retrieval depends on the expertise with the semantic facts to be retrieved. Implications for models of face identification and naming are discussed. 相似文献
