In four studies, 3-, 6-, and 9-month-old human infants were tested in a discrimination learning task in which visual fixation to a particular stimulus or lateral position was reinforced with an auditory stimulus. In Experiment 1, all age groups exhibited acquisition, extinction, and reinstatement of fixation to the reinforced target or position. Experiment 2 revealed that 3-month-olds retained the positional discrimination but not the stimulus discrimination after a 5-min delay between acquisition and extinction; older infants retained both types of discriminations. In Experiments 3 and 4 we investigated a possible developmental shift in the dominance of positional versus stimulus cues by training infants on displays in which stimulus and position were confounded and then by dissociating the cues on test trials. Results from both experiments indicated positional cue dominance for young infants and stimulus cue dominance for older infants. The findings are discussed in terms of differences in the attentional demands elicited by proprioceptive versus exteroceptive cues.  相似文献

Magazine-trained observer rats confronted a conspecific demonstrator pushing a joystick to the right or to the left for food reward before the observers were given access to the joystick from the position previously occupied by the demonstrator and rewarded for responses in both directions. For half of the observers (group 0), the joystick was in the same position when acted upon by demonstrators and observers; for the other half (group 180) the manipulandum was rotated 180 within its mounting between observation and test. As in previous experiments using this bidirectional control procedure, rats in group 0 showed demonstratorconsistent responding-that is, they pushed the joystick in the same direction, relative to the actor's body, as had their demonstrators. However, group 180 showed a reverse effect: reliable demonstrator-inconsistent responding. These results suggest that attractive odour or taste cues deposited by demonstrators on the side of the joystick contralateral to the direction of responding are sufficient to produce demonstrator-consistent responding in the bidirectional control procedure.  相似文献

ABSTRACT

O’Donohue has identified 37 criticisms of the American Psychological Association’s Ethical Principles of Psychologists and Code of Conduct (Ethics Code), although many of his criticisms go far beyond what is found written in the APA Ethics Code, to include the process of adjudicating ethics complaints by the American Psychological Association Ethics Committee, and the process by which the Ethics Code was developed. The authors claim that a major shortcoming of O’Donohue’s article is that he adopted an unrealistically expansive role for the Ethics Code that was not clearly linked to furthering the goals of the ethics code revision.  相似文献

Typical emotions share important features with paradigmatic intentional states and therefore might admit of distinctions made in theory of intentionality. One such distinction is between attitude and content, where we can specify the content of an intentional state separately from its attitude, and therefore, the same content can be taken up by different intentional attitudes. According to some philosophers, emotions do not admit of this distinction, although there has been no sustained argument for this claim. In this article, I argue that the way values figure in emotional experience qualifies the content of emotional experience such that the attitude‐content distinction cannot be applied.  相似文献
