On Alan Turing's anticipation of connectionism   总被引:2,自引:0,他引:2  
It is not widely realised that Turing was probably the first person to consider building computing machines out of simple, neuron-like elements connected together into networks in a largely random manner. Turing called his networks unorganised machines. By the application of what he described as appropriate interference, mimicking education an unorganised machine can be trained to perform any task that a Turing machine can carry out, provided the number of neurons is sufficient. Turing proposed simulating both the behaviour of the network and the training process by means of a computer program. We outline Turing's connectionist project of 1948.In Memory of Robin Gandy  相似文献

You'll Never Believe This: Irony and Hyperbole in Expressing Surprise   总被引:2,自引:0,他引:2  
Three experiments compared how people comprehend irony and hyperbole as expressing surprise. Experiment 1 demonstrated that, when irony and hyperbole are used together, they express more surprise than if either is used alone. There was no difference between the degree of surprise expressed by hyperbole and irony, although both expressed more surprise than literal commentary. Experiment 2 revealed that, when a speaker has exaggerated about some unexpected event, as much surprise is expressed by very slight, realistically possible hyperbole as by outlandish, impossible hyperbole. In a third experiment the range of possible levels of hyperbole tested in Experiment 2 was shown to cause differences in how easy it was to determine that a speaker was surprised at some turn of events. The results are discussed in terms of theories of irony and hyperbole comprehension.  相似文献

This study investigated the relationship between acquisition of psychoeducational principles and symptomatic improvement in depressed in-patients. One hundred and twenty-three inpatients hospitalized on a Cognitive Therapy Unit were administered the Test of Cognitive Behavioral Principles (TCBP) and the Beck Depression Inventory at admission and discharge. It was predicted that the TCBP scores would be higher at discharge than at pre-testing at admission. Further, it was hypothesized that the higher TCBP scores at post-test would be significantly correlated with lower Beck Depression Inventory scores at post-test. The results revealed that inpatients' TCBP scores improved over the course of treatment supporting the first hypothesis. However, the data did not support the second hypothesis as there was not a significant relationship between the TCBP scores and the BDI scores at discharge. The results are discussed in terms of clinical, theoretical, and methodological implications.  相似文献

Although I became a parapsychologist in part to help me understand the near-death experience (NDE) I had in 1952 as an undergraduate, it was not until 1990 that I began to integrate my NDE into my life. Doing so alerted me to the role the larger cultural context plays in regard to NDEs and other exceptional human experiences (EHEs). I propose not only that we need to draw on cultural resources to amplify the meaning of our exceptional human experiences, but that EHEs themselves carry the seeds of cultural change.  相似文献

The current research advances a social dilemma analysis of commuting, examining the roles of preexisting personality differences in social value orientation (i.e., prosocial vs. proself orientation) and trust (i.e., a general belief in the honesty and cooperative intentions of others) in determining preferences for collectively desirable commuting options: preferences for commuting by public transportation (Study 1) and carpooling (Study 2). Consistent with predictions, both studies revealed that, relative to p of prosocials, preferences of proselfs were more strongly associated with beliefs about the relative efficiency of cars (i.e., an outcome affecting personal well-being). Also, greater preferences for collectively desirable actions were observed among prosocials with high trust—relative to prosocials with low trust and proselfs with high or low trust—providing support for the claim that 2 conditions (i.e., prosocial goals and trust in others) must be met to obtain collectively desirable commuting preferences.  相似文献

A review indicates that (a) comparatively little is known about the common phenomenon of lifelong mild bad feelings, and (b) psychotherapy has generally overlooked an effective focus on this enigmatic feeling state. As an invitation for clinicians to provide more attention to this feeling state, a proposal is suggested toward one way of freeing a patient of lifelong mild bad feelings in the course of a session.  相似文献

To what extent do differences in biologicalsexand psychological gender identity influence affectivereactions to different genres of film? In order toaddress this question, this investigation examined the impact of sex and gender roleself-perceptions on viewers' responses to neutral,melodramatic, and violent film segments. Working with apredominantly Caucasian population (93% Caucasian) at asoutheastern university, the results emphasize theimportance of sex and gender role self-perceptions onviewers' affective responses to media entertainment. Theimplications of these findings are discussed.

EXPANDING THE MOTHER-CHILD PARADIGM   总被引:1,自引:0,他引:1  
Reliance on the mother–child dyad as the primary context for under–standing child development has caused fathers to be underrepresented in published research on child development and developmental psychopathology. In order to investigate whether this pattern was also evident in the work of future psychologists, we reviewed Dissertation Abstracts from 1986 through 1994. Results showed that fathers were the focus of significantly fewer dissertation studies (10.5%) than were mothers (59.5%) or both parents (30.0%). We argue that essentializing the mother–child bond is a political philosophy about the roles of men and women that places the discipline of psychology at risk for inadvertently becoming an apologist for the neoconservative political right. Specific suggestions for revising graduate training are presented. The social policy implications for continuing this trend into the next generation of psychologists are discussed.  相似文献

To investigate how gender, ethnicity, age and education influence aggressiveness, we surveyed 115 male and female college students (56% male; 50% Anglo and 26% Hispanic) and 79 persons (72% male; 92% Anglo) working on a military base. Participants were administered the Buss-Perry Aggression Questionnaire and asked about their own aggressive behaviors. In both samples, men scored significantly higher than women on the Physical Aggression scale of the Aggression Questionnaire but not on the other scales. In the military sample, men indicated that they expected to behave more aggressively than women. Positive correlations among different aspects of aggressiveness were found for both men and women. Increasing age and education were associated with lower aggressiveness in both genders, suggesting that aggressiveness may be susceptible to modification over the course of one's life.We would like to thank Angela Bennett, Gail Bliss, Kayleigh Carabajal, Julie Depree, Carmen Gonzales, Deborah Good, Scott Griffin, Gladys Herrera, George Selix, Ruth Tangman, and Jon Woodland for their assistance with the development, distribution, and coding of the questionnaire.  相似文献

A number of well-described, controlled studies assessing cancer support group intervention support their effectiveness. All of these experimental groups have been close-ended and typically involve six to eight weekly sessions. Because many cancer patients are unable or unwilling to participate in closed, extended-session groups, there is particular need for analysis of the effectiveness of short-term, open-ended groups. Additionally, objective measures are needed to delineate the factors contributing to a successful outcome in cancer support groups. We used the Short Form of the Group Climate Questionnaire (GCQ-S) to characterize 23 sessions in an open-ended, short-term, Veterans Hospital based cancer support group. The cancer group scored significantly lower on the Avoiding and Conflict dimensions (p<.001) compared to a normative psychotherapy group sample. There was no difference on the Engaged dimension. This pilot study suggests that a cancer support group in this setting can create an environment where members are cohesive and take responsibility for their own change process, while keeping interpersonal conflict to a minimum. Based on these preliminary findings, we encourage controlled clinical trials examining the efficacy of open-ended cancer support groups.At the time of this study, Dr. Daroff was a resident in Psychiatry, University of California, San Francisco.  相似文献
