Between 1919 and 1956, psychologists at the University of Toronto built a research program in developmental psychology on a functionalist, holistic, and ecological basis. They conducted longitudinal studies on mental health in growing children in educational settings instead of in laboratories and formed strong alliances with the local educational system in order to do so. They initially defined mental health as adjustment and considered conditions within schools to be conducive to its attainment. After developing a psychological theory of personality development, they came to view educational conditions as discouraging the development of mental health. The alliance between the educational system and psychology consequently unraveled, and the program declined. 相似文献
Adaptation experiences of 1.5-generation Asian American college students (N = 10) were examined using the consensual qualitative research method. Results indicated 4 domains of adaptation experiences: preimmigration experiences, acculturation and enculturation experiences, intercultural relationships, and support systems. Participants reported that English proficiency played a significant role in their initial adjustment. Currently, most of the participants reported feeling identified with both the U.S. and Asian cultures. Some participants reported having experienced racism in the past. Many participants noted that they currently have no difficulty establishing friendships with culturally different persons. Participants reported currently feeling most close to friends of a similar background and that they usually seek support from friends, family, and religious organizations, but not from a psychologist or counselor. 相似文献
To investigate amnesia between identities in dissociative identity disorder (DID), the authors assessed explicit and implicit memory performance on a directed-forgetting task in 12 DID patients who switched from one state to an "amnesic" state between presentation and memory testing. DID patients were instructed either to remember or to forget neutral and emotional words. Besides an overall decrease in explicit memory, patients demonstrated selective forgetting of to-be-forgotten, but not of to-be-remembered words in the amnesic state. Patients did not exhibit any directed forgetting within the same state. Implicit memory was fully preserved across states. Independent of state, patients recalled more emotional than neutral information. These results may extend the conceptualization of memory processes in DID, suggesting an important role for retrieval inhibition. 相似文献
Patients with Parkinson's disease (PD) have repeatedly demonstrated reduced sequence-specific learning effects in serial reaction time tasks (SRTs). Previous research with PD patients has mainly employed the 'classical' SRT task, involving a spatially compatible assignment of stimuli and responses. From cognitive research, it is known that spatial compatibility triggers rapid, automatic responses in the direction of the stimulus. Automatic responding has shown to be disinhibited in PD patients and may therefore interfere with stimulus anticipation during the learning process. The aim of the present study was to test this hypothesis by investigating if reduced sequence-specific learning depends on spatial stimulus-response compatibility. PD patients and age-matched controls were examined either with an SRT variant involving central stimulus presentation, thereby preventing automatic linking of stimulus and response locations, or with a spatially compatible SRT task. Patients showed reduced sequence-specific learning effects only when the stimulus-response assignment was spatially compatible. This pattern of results confirms the hypothesis that sequence learning deficits in PD may result from a predominance of automatic response activation over learning-based stimulus anticipations during the learning phase. 相似文献
This appearance condition of fallacies refers to the phenomenon of weak arguments, or moves in argumentation, appearing to be okay when really they aren’t. Not all theorists agree that the appearance condition should be part of the conception of fallacies but this essay explores some of the consequences of including it. In particular, the differences between committing a fallacy, causing a fallacy and observing a fallacy are identified. The remainder of the paper is given over to discussing possible causes of mistakenly perceiving weak argumentation moves as okay. Among these are argument caused misperception, perspective caused misperception, discursive environment caused misperception and perceiver caused misperception. The discussion aims to be sufficiently general so that it can accommodate different models and standards of argumentation that make a place for fallacies.
When the probability of a single member of a set of mutually exclusive and exhaustive possibilities is judged, its alternatives are evaluated as a composite "residual" hypothesis. Support theory (Rottenstreich & Tversky, 1997; Tversky & Koehler, 1994) implies that the process of packing alternatives together in the residual reduces the perceived evidential support for the set of alternatives and consequently inflates the judged probability of the focal hypothesis. Previous work has investigated the global weights that determine the extent to which the overall evidential support for the alternatives is discounted by this packing operation (Koehler, Brenner, & Tversky, 1997). In the present investigation, we analyze this issue in greater detail, examining the local weights that measure the specific contribution of each component hypothesis included implicitly in the residual. We describe a procedure for estimating local weights and introduce a set of plausible properties that impose systematic ordinal relationships among local weights. Results from four experiments testing these properties are reported, and a local-weight model is developed that accounts for nearly all of the variance in the probability judgments in these empirical tests. Local weights appear to be sensitive both to the individual component with which they are associated and to the residual hypothesis in which the component resides. 相似文献
The present paper is primarily a response to Watanabe, Sakamoto, and Wakita's 1995 paper “Pigeons' Discrimination of Paintings by Monet and Picasso.” Our main criticism is that the key term concept, and in particular the way in which a class of stimuli is specified, remains equivocal. We argue that it is only useful to study categorization if the organism in question can be expected to have access to the information that is used in defining the classes, and that evidence for categorization requires selective responses that cannot be attributed to similarity in features that are not essential to the classification. 相似文献
A unidimensional latent trait model for continuous ratings is developed. This model is an extension of Andrich's rating formulation which assumes that the response process at latent thresholds is governed by the dichotomous Rasch model. Item characteristic functions and information functions are used to illustrate that the model takes ceiling and floor effects into account. Both the dichotomous Rasch model and a linear model with normally distributed error can be derived as limiting cases. The separability of the structural and incidental parameters is demonstrated and a procedure for estimating the parameters is outlined. 相似文献
