We modified the standard procedure for administering finger pressure pain in order to assess the extent to which subjects biased their reports of pain reduction when exposed to compliance-inducing instructions. Experiment 1 used only highly hypnotizable subjects and found that compliance-induced reductions in reported pain were about half as large as the reported reductions produced by hypnotic analgesia suggestions. Experiment 2 used low as well as high hypnotizables and administered hypnotic or nonhypnotic analgesia instructions and compliance instructions to the same subjects on separate pain trials. Reported pain reductions produced by hypnotic and nonhypnotic analgesia suggestions and those produced by compliance instructions were substantially and significantly correlated. Furthermore, hypnotizability correlated with compliance-induced reported pain reductions as highly as it correlated with the reported reductions produced by hypnotic analgesia suggestions. Among high hypnotizables (but not low hypnotizables) compliant responding was predicted by social desirability. The findings of both studies indicate that compliance strongly influences the reports of hypnotic and nonhypnotic analgesia proffered by high hypnotizables. The role of compliance in the pain reductions reported by low hypnotizables is less clear-cut. 相似文献

Conclusion The legacy of the Swampscott conference 25 years ago is palpable. The scientific accomplishments have been substantial. The four agendas I have presented for the future development of the field depend upon psychologists as individuals and psychologists as participants in our departments, colleges, universities, professional societies, and peer review panels to reduce the constraints that limit the definition and study of psychological phenomena in community settings (Schneider, 1990). As these constraints are addressed, new social norms can be established to expand and diversify the research process. There are some explicit positive side effects that can occur. A new working social structure can be created for how universities and communities can be resources for each other.The four topics I have presented are agendas for keeping at the task of generating active and expanding scientific traditions. These topics when addressed in the context of collaboration with other disciplines and citizens can develop an empirical base of shared wisdom about how to carry out community psychology research. In these ways the benefits of community psychology research can become more empowering for the public and more and more systemic for the scholar.These comments were presented as an Invited Address at the 2nd annual meeting of the American Psychological Society, June 8, 1990, Dallas, Texas.The following persons took time to read and comment on earlier drafts of these comments. I have benefited very much from their appraisals. Eileen Altman, Daniel Cervone, Seeley Chandler-Kelly, Nancy Dassoff, Penny Foster-Fishman, Steve Goldston, Peter Graves, Kenneth Heller, Robert E.

This study presents initial standardization data on the Sutter- Eyberg Student Behavior Inventory (SESBI), a teacher- completed measure of disruptive classroom behaviors. SESBIs were completed on 1116 children in kindergarten through fifth grade in a rural eastern Washington school district. Various analyses (Cronbach's alpha, corrected item- total correlations, average interitem correlations, principal components analyses) indicated that the SESBI provides a homogeneous measure of disruptive behaviors. Support was also found for three factors within the scale (e.g., overt aggression, oppositional behavior, and attentional difficulties). While the child's age did not have a significant effect on the SESBI, the child's gender did have a significant effect on scale scores as well as on most of the items, with males being rated more problematic than females. The SESBI was also able to discriminate between children in treatment for behavioral problems or learning disabilities and children not in treatment.The authors would like to acknowledge the support of the teachers in the Pullman School District, whose kind help and assistance made the study possible. Special thanks are also extended to Todd Sosna, Christine Ladish, and Lee Sternberger for their helpful comments on earlier versions of the paper. Preparation of this study was supported in part by funds provided to G. Leonard Burns by Washington State University. 相似文献

Ascertained if being a member of a statistical minority influences children's adjustment in school, as measured by the AML, a teacher-administered adjustment rating scale. Teachers from a southwest school district evaluated elementary students on aggressive, acting-out behaviors, moody-internalized behaviors, and learning difficulties. Analyses conducted on 376 students revealed significant effects of statistical minority status on certain dimensions of adjustment ratings for both Hispanic and Anglo students. Hispanic students in the statistical minority received poorer ratings on the moodiness dimension of the AML than nonminority Hispanic students. Anglo students in the statistical minority received poorer ratings on the aggression dimension of the AML than nonminority Anglo students. These results were interpreted in terms of cultural differences in coping with statistical minority status. Traits commonly exhibited within a culture may intensify and be perceived as maladaptive when stress resulting from being a minority occurs. Implications of the finding that statistical minority status within the school environment influences adjustment are discussed. 相似文献

A componential analysis of pacemaker-counter timing systems 总被引:1,自引:0,他引:1
J G Fetterman P R Killeen 《Journal of experimental psychology. Human perception and performance》1990,16(4):766-780
Why does counting improve the accuracy of temporal judgments? Killeen and Weiss (1987) provided a formal answer to this question, and this article provides tests of their analysis. In Experiments 1 and 2, subjects responded on a telegraph key as they reproduced different intervals. Individual response rates remained constant for different target times, as predicted. The variance of reproductions was recovered from the weighted sum of the first and second moments of the component timing and counting processes. Variance in timing long intervals was mainly due to counting error, as predicted. In Experiments 3-5, unconstrained response rate was measured and subjects responded at (a) their unconstrained rate, (b) faster, or (c) slower. When subjects responded at the preferred rate, the accuracy of time judgment improved. Deviations in rates tended to increase the variability of temporal estimates. Implications for pacemaker-counter models of timing are discussed. 相似文献

The purpose of this comment is to point out some potential pitfalls in the study of similarity judgments, particularly with regard to comparison of similarity judgments between modalities. These are discussed in the context of the article by Ritov, Gati, and Tversky (1990). 相似文献

Discriminative properties of morphine that modulate associations between tastes and lithium chloride
G M Martin M Gans D van der Kooy 《Journal of experimental psychology. Animal behavior processes》1990,16(1):56-68
Wistar rats learned to withhold consumption of a target solution when morphine preceded presentation of the target solution and lithium chloride (LiCl) and to consume the same target solution when saline preceded the presentation of the solution. After this serial feature discrimination training, morphine did not block the formation of a Pavlovian association between saccharin and LiCl but did suppress consumption of familiar tap water. After Pavlovian conditioning, morphine blocked the formation of an association between saccharin and LiCl but did not suppress consumption of a familiar tap water solution. The roles of morphine and saline can be interchanged. It appears that the morphine discriminative stimulus is calling up a representation of neither the conditioned stimulus nor the unconditional stimulus alone, but rather a modified representation of some aspect of their association. 相似文献

A kinematic analysis of anticipatory coarticulation in the speech of anterior aphasic subjects using electromagnetic articulography 总被引:1,自引:1,他引:0
An investigation was made into the extent and time course of anticipatory coarticulation in the speech of two normal and two anterior aphasic, German-speaking subjects. Both labial and velar coarticulation gestures were investigated. Subjects produced sentences containing target words contrasting in postconsonantal vowel rounding (e.g., [geli:ge]/[gely:gel]) and in nasality (e.g., [ti:de]/[ti:ne]). Speech kinematics were monitored by means of electromagnetic articulography. The data revealed that for correct productions, aphasic speakers' coarticulatory patterns were more highly variable than those of control subjects. These differences, however, were found chiefly for spatial displacement characteristics, while the temporal aspects of articulator movement necessary for anticipatory coarticulation appeared largely intact. Articulator mistiming did not appear to explain a small corpus of stop/nasal substitution errors produced by one of the aphasic speakers. 相似文献

In category classification tasks, typicality effects are usually found: accuracy and reaction time depend upon distance from a prototype. In this study, subjects learned either verbal or nonverbal dot pattern categories, followed by a lateralized classification task. Comparable typicality effects were found in both reaction time and accuracy across visual fields for both verbal and nonverbal categories. Both hemispheres appeared to use a similarity-to-prototype matching strategy in classification. This indicates that merely having a verbal label does not differentiate classification in the two hemispheres. 相似文献

Sperling, Landy, Dosher, and Perkins (1989) proposed an objective 3D shape identification task with 2D artifactual cues removed and with full feedback (FB) to the subjects to measure KDE and to circumvent algorithmically equivalent KDE-alternative computations and artifactual non-KDE processing. (1) The 2D velocity flow-field was necessary and sufficient for true KDE. (2) Only the first-order (Fourier-based) perceptual motion system could solve our task because the second-order (rectifying) system could not simultaneously process more than two locations. (3) To ensure first-order motion processing, KDE tasks must require simultaneous processing at more than two locations. (4) Practice with FB is essential to measure ultimate capacity (aptitude) and, thereby, to enable comparisons with ideal observers. Experiments without FB measure ecological achievement--the ability of subjects to extrapolate their past experience to the current stimuli. 相似文献
