The present study was designed to investigate what variables discriminate individuals who actively work to promote disarmament from individuals who share the same attitudes but remain inactive. It is argued that if a person appraises nuclear war as an unlikely event, then it is not necessary to contemplate what can be done to prevent it. In contrast, if a threat is perceived, several possible coping strategies might be available, one of which is activism. However, activism is viable only if an individual believes that collectively the public can make a difference. Results of two surveys, one conducted with 142 peace activists across Canada and another with a random sample of 33 adults from the cities of Kitchener and Waterloo, Ontario, who are not active in the peace movement, confirm that perceptions of threat and belief in collective control are powerful discriminating variables. The implications of these findings for educating and mobilizing the public in the pursuit of disarmament are discussed.  相似文献

The aim of this investigation was to gauge the comparative research performance of university departments of psychology in Britain. The performance indicator was the number of publications per departmental staff member in the journals of the British Psychological Society (BPS) during the seven-year period 1983–1989. The contents of these journals were thoroughly searched, and articles written by members of university psychology departments in Britain were counted. The number of publications of each psychology department was divided by the size of the department in the corresponding year and the resulting annual figures were summed to determine the number of publications in BPS journals per departmental staff member over the seven-year period. These research performance figures correlated significantly with an earlier measure of departmental research performance based on publications in the seven European psychological journals with the highest citations per published article and with recent performance indicators based on other criteria  相似文献

Delayed matching-to-sample was studied in the pigeon using a procedure which precisely controlled the presentation time of the sample stimulus. Experiments 1 and 2 revealed that (a) accuracy of matching increased as a negatively accelerated function of presentation time, (b) accuracy declined when an interstimulus interval was introduced between successive presentations of the sample stimulus, and (c) the rate at which accurate matching was restored after an interstimulus interval was greatest when the initial presentation of the sample was short and the interval was long. It was concluded that a theory of STM based on the growth and decay of trace strength could account adequately for all of these findings. Experiment 3 studied trace interaction by presenting two sample stimuli first in succession and then simultaneously for choice. Predictions from trace competition theory about the specific lengths of presentation of these stimuli at which choice of the second stimulus should be 50% or deviate systematically below 50% were not supported. It appears that a recency mechanism in addition to competition is necessary to explain trace interaction effects.  相似文献

Two differential eyelid conditioning studies employed grammatically correct and incorrect adjective-noun phrases as conditioned stimuli. For different groups of subjects, the nouns were either high or low in imagery. The hypothesis that congruency between grammatical correctness and reinforcement consequences (i.e., the aversive stimulus contingent upon presence of incorrect rather than correct grammar) would facilitate conditioned discrimination was not supported, but the hypothesis that high noun imagery would facilitate differential response to syntax received strong support. Cognitive awareness of the syntactic discriminandum was also related to effective differential responding, as well as being implicated as a mediating mechanism in the imagery effects. Finally, performance was also significantly related to conditioned-response topography, with better conditioned discrimination by voluntary-form (V) than by conditioned-form (C) responders, and also evidence of more effective utilization of contingency awareness by Vs than by Cs.  相似文献

This experiment investigated speed of processing the grammaticality of phrases consisting of the adjective “one” or “two” followed by a singular or plural noun. The subject’s task was to press one of two keys, depending upon whether the phrase was grammatically correct or incorrect. There were eight types of phrases, formed by the factorial combinations of singular or plural adjectives, singular or plural nouns, and high or low noun imageD’. These served as within-subjects variables. Between-subjects variables were the factorial combinations of sex of subject, duration of stimulus phrase (.2 or 2.5 sec), and hand assigned to the correct-grammar key. A fourth between-subjects variable was whether or not the subject reported using an artificial phrase-scanning strategy to determine grammaticality. Correct grammar, singular noun form, high noun imagery, and reported use of the strategy all produced highly significant reductions in reaction times. Only 1% of the interactions were significant. A multistage serial processing model that could be based upon Sternberg’s additive factor paradigm or even Donders’ subtraction method was found to be highly successful in describing the results.  相似文献

This study explored the relationship between anorexic behavior and selected dimensions of body image. Anorexic behavior was assessed by two scales, the Eating Attitudes Test (EAT 26) (Garner, Olmstead, Bohr, & Garfinkel, 1982) and the Eating Disorders Inventory (EDI) (Garner, Olmstead, & Polivy, 1983). Predictor variables, selected dimensions of body image, physical attractiveness, self-esteem, and physical effectiveness, were measured by scales adapted by Lerner and Karabenick (1974) and Lerner, Orlos, and Knapp (1976). Multiple regression techniques were used to determine how much of the tendency toward anorexic behavior can be predicted by selected dimensions of body image. The major focus of the analysis was to explore the contributions of each of the dimensions of body image to predicting tendencies toward anorexic behavior in adolescents. The research sample consisted of 169 high school students, aged 15 to 18, who were enrolled in health, physical education, or psychology classes in the spring of 1983. Results indicated that the dimension of self-esteem was the major factor in the prediction of anorexic behaviors as measured by the Eating Disorders Inventory.  相似文献

In two experiments, independent groups of pigeons were trained on an identity matching task involving line orientations as sample and comparison stimuli. For some birds an overhead houselight was illuminated continuously throughout each training session. For other birds the houselight was never illuminated during training sessions. During subsequent testing, the lighting conditions during the delay were the same as in training on some trials, but on other trials they were opposite those of training during either the entire delay (Experiment 1) or during a portion of the delay (Experiment 2). In birds trained with the houselight off, turning the houselight on during the delay produced a large and enduring disruption in matching accuracy. On the other hand, in birds trained with the houselight on, turning the houselight off during the delay produced only a moderate and temporary disruption in matching accuracy. These findings are inconsistent with the prevailing view that retroactive interference in pigeons is a function of a change in illumination level relative to that which prevailed during training. In pigeons, as in monkeys, sustained retoactive interference effects obtain only when the level of illumination is increase during the delay interval.  相似文献

A prognosis for the dual career marriage with and without children is developed and evaluated. A brief history is given, current shifts in sex-role stereotypes within and out of marriage are delineated, advantages and satisfactions as well as disadvantages and problems of the dual career marriage are discussed. Some particular issues facing clergy couples are cited and therapeutic considerations are briefly touched upon. Pertinent research and literature in the field of Marriage, Family, and Child Counseling and Pastoral Counseling is reviewed throughout.  相似文献

A classic study by Becker and Geer proposed that medical students underwent cycles of value development during medical school. Initially, high levels of humanitarianism declined then re-emerged as students neared graduation. Declines in humanitarianism were accompanied by increased interest in extrinsic rewards. This paper examines value development in medical school for 200 men and women recent graduates. Questionnaire data collected at three times were used to develop scales of students' orientations toward humanitarianism and extrinsic rewards. We find partial verification for value-change patterns described by Becker and Geer, but gender variations are stronger than time variations. Women showed stronger humanitarianism and stronger interest in work conditions at all times than did men. Interest in extrinsic rewards increased for students of both genders but never surpassed humanitarianism in relative importance.The authors appreciate aid in data analysis from Daniel Duross and Tod Sloan and comments on earlier drafts on the paper by Camille Wortman and Roland K. Hawkes. The research was supported partially by a grant from the Spencer Foundation. An earlier version of the paper was presented at the American Sociological Association Meeting in Detroit.  相似文献

The paper concerns the relation between frequency estimates and recognition decisions. Theories postulating that these two measures reflect independent retrieval processes and theories that postulate that frequency estimation and recognition are mutually dependent processes are discussed. Empirical results apparently supporting both positions are also reviewed. Results of experiments in which instructions and test methods are varied factorially and results of conditional and correlational analyses establishing a dependency between frequency estimates and recognition decisions are taken as evidence supporting the dependent process view. However, the results do not permit discrimination within this class of theories.  相似文献
