ABSTRACT— Contemporary theories of learning typically assume that learning is driven by prediction errors—in other words, that we learn more when our predictions turn out to be incorrect than we do when our predictions are correct. Results from the recording of electrical brain activity suggest one mechanism by which this might happen; we seem to direct visual attention toward the likely causes of previous prediction errors. This can happen very rapidly—within less than 200 milliseconds of the error-causing object being presented. It is tempting to infer that if learning is driven by prediction errors, then little can be learned in the absence of feedback. Such a conclusion is unwarranted. In fact, the substantial learning that is sometimes the result of simple exposure to objects can also be explained by processes of directing attention toward the likely causes of previous prediction errors. 相似文献

Anxiety disorders are known to run in families [Turner, S. M., Beidel, D. C., & Costello, A. (1987). Psychopathology in the offspring of anxiety disorder patients. Journal of Consulting and Clinical Psychology, 55(2), 229–235] and environmental factors may largely account for the concordance between parental and child anxieties. Cognitive psychology models emphasise the importance of interpretive biases towards threat in the maintenance of anxiety and it is well established that anxious adults and children display similar interpretive biases and that these biases in anxious parents and their children are correlated. This raises the question of whether anxious cognitions/cognitive style may be transmitted from parent to child. We propose that this is more likely if anxious parents demonstrate interpretive biases not only about potential threats in their own environment but also about potential threats in their child's environment. Forty parents completed a recognition memory measure of interpretation bias adapted from Eysenck, Mogg, May, Richards, and Mathews (1991) [Bias in interpretation of ambiguous sentences related to threat in anxiety. Journal of Abnormal Psychology, 100(2), 144–150] to measure biases in response to potentially threat provoking situations involving themselves and their child. The interpretive biases demonstrated by parents were similar across situations involving themselves and their children. As expected, parental interpretive biases were further modified by anxiety with higher levels of parental anxiety associated with more negative interpretive biases about situations in their own and their child's environment, although this association was significantly stronger for potentially threat provoking situations in their own environment. These results are consistent with parent's interpretive biases extending beyond their own environment into their child's environment, although future research should continue to consider the mechanisms by which anxious parents may transmit fear cognitions to their children. 相似文献

The Dynamical Challenge 总被引:1,自引:0,他引:1
Recent studies such as Thelen and Smith (1994), Kelso, (1995), Van Gelder, (1995), Beer, (1995), and others have presented a forceful case for a dynamical systems approach to understanding cognition and adaptive behavior. These studies call into question some foundational assumptions concerning the nature of cognitive scientific explanation and (in particular) the role of notions such as internal representation and computation. These are exciting and important challenges. But they must be handled with care. It is all too easy, in this debate, to lose sight of the explanatorily important issues and to talk at cross-purposes, courtesy of the (surprisingly) various ways in which different theorists often conceive the key terms. The primary goal of the present paper is thus a modest one: to begin to clarify just what is at issue and to highlight some of the most central and pressing concerns. In so doing, we may hope to develop a constructive framework for future debate. In addition, I try to open up a space of intermediate options—ways in which dynamical and representational/computational understandings may sometimes afford complementary (rather than competing) perspectives on adaptive success. 相似文献

A variety of abnormal sensory/motor behaviors associated with electrical discharges recorded from the bilateral brainstem were induced in adult WKY rats by mechanical (electrode implants) and DC electrical current stimulations and by acute and chronic administration of cocaine. The electrode implant implicated one side or the other of the reticular system of the brainstem but subjects were not incapacitated by the stimulations. Cocaine (40 mg/kg) was injected subcutaneously for an acute experiment and subsequent 20 mg/kg doses twice daily for 3 days in a chronic study. Cocaine generated more abnormal behaviors in the brainstem perturbation group, especially the electrically perturbated subjects. The abnormal behaviors were yawning, retrocollis, hyperactivity, hypersensitivity, “beating drum” behavior, squealing, head bobbing, circling, sniffing, abnormal posturing, and facial twitching. Shifts in the power frequency spectra of the discharge patterns were noted between quiet and pacing behavioral states. Hypersensitivity to various auditory, tactile, and visual stimulation was present and shifts in the brainstem ambient power spectral frequency occurred in response to tactile stimulation. These findings suggest that the brainstem generates and propagates pathological discharges that can be elicited by mechanical and DC electrical perturbation. Cocaine was found to activate the discharge system and thus induce abnormal behaviors that are generated at the discharge site and at distant sites to which the discharge propagates. Cognitive functions may also be involved since dopaminergic and serotonergic cellular elements at the brainstem level are also implicated. 相似文献

The elegance of the techniques developed by the Milan group has tended to blind family therapists to the many problems inherent in their approach. A close reading of their work uncovers many ethical and political issues which need to be addressed. This paper is a preliminary attempt to develop a critique of the group's method which recapitulates some of the most alienating aspects of the traditional medical model. It will concentrate solely on a critical reading of Paradox and Counterparadox and will not seek to come to terms with the more recent evolution of the Milan school. 相似文献

Binocular forced-choice detection performance was measured in three stereoblind observers and four observers with normal stereopsis. Detection rates of normal observers were greater than expected from probability summation, while those of the stereoblind observers were near or at a level expected from probability. It is concluded that binocular summation is reduced or absent in stereoblind persons. 相似文献

The purpose of this article is to provide easily accessible readability information for 49 parent- and 35 child- and adolescent-report measures commonly used by clinicians and researchers. There is a great deal of variability in reading ability required across measures. The majority of parent-report measures (65%) required reading ability above the 8th grade level. The average child-/adolescent-report measure required reading ability above the 6th grade level. Given the potential contribution of readability to a measure's reliability, validity, and overall utility, examining and accounting for readability should be a more common practice in test construction and administration. 相似文献

Why do people dislike art that they find meaningless? According to terror management theory, maintaining a basic meaningful view of reality is a key prerequisite for managing concerns about mortality. Therefore, mortality salience should decrease liking for apparently meaningless art, particularly among those predisposed to unambiguous knowledge. Accordingly, mortality salience diminished affection for modern art in Study 1, and this effect was shown in Study 2 to be specific to individuals with a high personal need for structure (PNS). In Studies 3 and 4, mortality salient high-PNS participants disliked modern art unless it was imbued with meaning, either by means of a title or a personal frame of reference induction. Discussion focused on the roles of meaninglessness, PNS, and art in terror management. 相似文献
