The differences in apparent prevalence of childhood hyperactivity between England and North America are more than 20-fold. This paper seeks to illuminate the reasons for the difference by applying a standard measure [Conners Teacher Rating Scale] to 437 English schoolchildren, aged 6 to 9 years, and comparing them with published surveys from the United States and Australasia. The rating scale had moderate interrater reliability and stability over time; it distinguished between children referred for psychiatric treatment and normal schoolchildren. Component analysis yielded a factor of hyperactivity-inattentiveness, distinct from conduct disorder. The mean hyperactivity scores of English children were higher than in most U.S. surveys but lower than in New Zealand. The national differences in rates of diagnosed hyperactivity are likely to reflect diagnostic inconsistency rather than true differences in children's behavior. 相似文献

Research investigating social values in interdependency situations has generally demonstrated age differences across the 5- to 10-year-old age range. However, the precise nature of these differences is unclear. Further, the differences in the social values of adults and children has not been addressed. The present study examined the social values of undergraduates and children using a measurement technique designed to allow an accurate inference of social values. Ninety-one 6- to 10-year-old children and 100 undergraduates rated the desirability of a set of outcomes which systematically varied with regard to the benefits to themselves and another person. Theoretically specified characteristics of the outcomes were then used to generate a regression equation predicting the desirability ratings separately for each individual. These regression equations were then clustered into groups of individuals who used decision rules characteristic of the major social values. The results indicate that the 8- to 10-year-old children, compared to the 6- to 7-year olds, more often expressed a social value involving equality and tended to less often express a social value involving superiority. Comparison of the social values expressed by the children and adults indicated that the adults more often expressed group-enhancement and individualism social values and less often expressed a social value involving superiority. 相似文献

ABSTRACT Because of the existence of severely defective humans it is commonly held that whatever consideration is due to all humans is also due to many other animals, and that therefore speciesism, or the readiness to prefer the interest of humans to those of other animals, is unjustified. After criticism of this reasoning a 'naturalised' speciesism, acknowledging, for example, the affinities between species, is articulated and defended. A key to this defence is the separation of the task of specifying morally significant differences between humans and other animals from the task of justifying the extension of consideration to defective humans. The conclusion is that more traditional vices than speciesism are chiefly to blame for the shabby treatment of animals by humans. 相似文献

This study examined the impact of nonsexist curricula and teacher's sex on children's sex role learning. Thirty-two boys and 32 girls, aged three to five, were equally divided among four programs: nonsexist curriculum, female director; nonsexist curriculum, male director; control curriculum, female director; and control curriculum, male director. Sex role discrimination and preference were measured at the beginning and end of a six-month period. Exposure to the nonsexist curriculum produced significantly greater reductions in sex stereotyping on all measures than exposure to the control curriculum. Moreover, children in the male-directed nonsexist program displayed greater decreases in stereotypic knowledge and preference for sex-typed children's activities than those in the female-directed nonsexist program, while children in the male-directed control program showed more stereotypic increases on these measures than their counterparts in the female-directed control program. Finally, children under the direction of an opposite-sex teacher exhibited less stereotypic changes in preference for adult activities than children under the direction of a same-sex teacher. Implications for early childhood programs are discussed.This research was partially supported by an Oregon State University Foundation grant from the Shell Foundation and a grant from the Milne Computer Center. 相似文献

Summary This article considers the study reported by Rossmann (1983) in which a failure to replicate the findings of Parkin, Lewinsohn and Folkard (1982) is reported. It is argued that Rossmann's findings could be attributed to methodological differences and, as such, do not constitute a replication failure. Guidelines for further replication attempts are offered. 相似文献

Representation of linear orders 总被引:1,自引:0,他引:1
D A Taylor J O Kim P Sudevan 《Journal of experimental psychology. Learning, memory, and cognition》1984,10(1):61-71
Two binary classification tasks were used to explore the associative structure of linear orders. In Experiment 1, college students classified English letters as targets or nontargets, the targets being consecutive letters of the alphabet. The time to reject nontargets was a decreasing function of the distance from the target set, suggesting response interference mediated by automatic associations from the target to the nontarget letters. The way in which this interference effect depended on the placement of the boundaries between the target and nontarget sets revealed the relative strengths of individual interletter associations. In Experiment 2, students were assigned novel linear orders composed of letterlike symbols and asked to classify pairs of symbols as being adjacent or nonadjacent in the assigned sequence. Reaction time was found to be a joint function of the distance between any pair of symbols and the relative positions of those symbols within the sequence. The effects of both distance and position decreased systematically over 6 days of practice with a particular order, beginning at a level typical of unfamiliar orders and converging on a level characteristic of familiar orders such as letters and digits. These results provide an empirical unification of two previously disparate sets of findings in the literature on linear orders, those concerning familiar and unfamiliar orders, and the systematic transition between the two patterns of results suggests the gradual integration of a new associative structure. 相似文献

Attributions for cancer and beliefs about control over cancer were examined for their association with adjustment to breast cancer. Although 95% of the respondents made attributions for their cancer, no particular attribution (e.g., stress, diet) was associated with better adjustment. Analyses of attributions of responsibility for the cancer to the self, environment, another person, or chance yielded only a negative relation between adjustment and blaming another person. In contrast, both the belief that one could now control one's cancer and the belief that others (e.g. the physician) could now control the cancer were significantly associated with good adjustment. Of the different types of control, cognitive control was most strongly associated with adjustment, behavior control was less strongly associated with adjustment, and information control and retrospective control were unassociated with adjustment. The theoretical and practical implications of these results are discussed. 相似文献

The influence of contextual stimuli on the conditioning and performance of responding to a discrete stimulus was examined in the US preexposure paradigm using both context shift manipulations and a measure of context conditioning. Four groups of rats received both repeated exposure to an electric shock US in one context (Context 1), and repeated nonshocked exposure to a second context (Context 2). Two additional groups of rats received exposure to these contexts, but never received shock presentations. Rats exposed to shock learned to escape from the stimuli of Context 1, but did not escape from the stimuli provided by Context 2. Rats not exposed to shock failed to escape from either context. All rats then received a single CER conditioning session in which four pairings of a 3-min noise CS and shock US were presented. Half the rats received those CS-US pairings in the excitatory Context 1, while the remaining rats received those pairings in the neutral Context 2. Finally, half the rats in each of the CER conditioning treatments received extinction test trials of the noise CS in Context 1, while the remaining rats received those test trials in Context 2. Thus, this design factorially manipulated the presence of excitatory or neutral contextual stimuli during both conditioning and testing of a discrete CS. In comparison with the two groups of rats never preexposed to shock alone, attenuation in acquisition of conditioned suppression observed during test trials occurred only when CER conditioning had been administered in the excitatory Context 1, and this effect was manifested when testing occurred in either the excitatory Context 1 or the neutral Context 2. These results support the model of R. A. Rescorla and A. R. Wagner (1972) (in A. H. Black & W. F. Prokasy (Eds.) Classical Conditioning II, pp. 64–99, New York: Appleton-Century-Crofts) which asserts that contextual stimuli and sicrete CSs compete for limited associative strength supportable by a given US. 相似文献

We examined articles with experiments published in the Journal of Applied Behavior Analysis and in Behavior Analysis in Practice from 2017 through 2021 to determine how frequently procedural fidelity was assessed. When procedural fidelity was assessed, we determined how often a measure of interobserver agreement for those fidelity data was provided. We also determined how often a measure of interobserver agreement for participants' behavior was provided. Across both journals and all years, 54.7% of relevant articles provided a measure of procedural fidelity. Of them, 17.7% provided a measure of interobserver agreement for procedural fidelity. In marked contrast, 96.4% provided interobserver agreement data for participants' behavior. It is unfortunate that applied behavior analysts frequently fail to provide procedural fidelity data and, when they do, often fail to provide interobserver agreement data for the fidelity data. Reviewers for, and editors of, behavior-analytic journals are encouraged to strongly consider the relative value of procedural fidelity and agreement on procedural fidelity measures when rendering recommendations on the suitability of a given submission. 相似文献

Affection deprivation is more aversive than excessive affection: A test of affection exchange theory
Affection exchange theory predicts that both excessive affection and affection deprivation are associated with poorer health, compared with receiving the level of affectionate communication that one desires. A similar yet-untested prediction is that affection deprivation is more aversive than excessive affection. This preregistered study tested both hypotheses on a battery of mental and physical health outcomes, including depression, loneliness, stress, physical pain, frequency of nightmares, and sleep quality, using a Census-matched sample of U.S. American adults (N = 827). As hypothesized, receiving the right amount of affection was associated with more health-supportive scores on all outcomes than either excessive or deficient affection. Similarly, excessive affection was associated with lower depression, loneliness, stress, and pain, and higher sleep quality, than affection deprivation. 相似文献
