Avoidance conditioning with shock contingent upon the avoidance response

Rats learned either a lever-press response, a shuttle response or a one-way crossing response, which produced one immediate shock but was instrumental in avoiding five identical shocks scheduled to occur later. These responses were acquired both with and without support of an escape contingency. These results support shock-frequency reduction as a sufficient condition for the acquisition and maintenance of avoidance.

The effects of spontaneous and voluntary facial reactions on surprise and humor

Two investigations were conducted to determine the nature of the relationship between facial reactions and surprise and humor ratings as suggested by the facial feedback hypothesis. In the correlational investigation, individual subjects showed a positive correlation between their spontaneous facial reactions and funniness ratings over 36 cartoons (within subjects). Subjects who were facially more reactive to all the cartoons, however, did not rate them as funnier than did subjects who were less facially reactive (between subjects). In the experimental investigation, spontaneous facial reactions were evoked by a discrepant weight and also were inhibited or amplified on verbal demand. Surprise and funniness ratings varied with spontaneous facial reactions but were unaffected when those reactions were voluntarily inhibited or amplified. The results were interpreted as not supporting the facial feedback hypothesis and suggested that facial reactions may only correlate with emotional experience.These investigations were supported by Ball State University Research Grants.     

The sensitization of humor responses to cartoons

It was hypothesized that a humor response to a cartoon in a series depends upon arousal or increased salience, both of which may be produced by preceding cartoons. A humor response, however, should eventually decline owing to habituation. Three experiments were conducted in order to determine if responding to cartoons with the same theme depends upon the cartoon's serial position. Facial responses and ratings of funniness increased over the first few cartoons, reflecting the effect of arousal or salience. It appears that the initial cartoons make the person more sensitive to later cartoons. A downward trend in responding was more apparent for facial responses than for funniness ratings. The evidence for habituation was weak, however, and did not seem occur to the experimenter-defined cartoon theme. Cartoons even representing the same theme may be too variable to permit habituation. It was suggested that cartoon researchers be aware of the effect of a cartoon's serial position on humor responses.The investigators would like to thank Michael Davis, Michael Mullins, and Elizabeth Weaver for their assistance in data collection and analyses.     

Principal components analyses of behavior problems in Jamaican clinic-referred children: Teacher reports for ages 6–17

Factor analyses of child behavior problems have often yielded two broadband syndromes, Overcontrolled (e.g., worrying, fearfulness, withdrawal) and Undercontrolled (e.g., restlessness, fighting, disobedience). We explored whether these two broad-band syndromes might be identified for youngsters in Jamaica. We obtained teacher reports for 320 clinic-referred Jamaican youngsters on a 24-item problem checklist designed by Jamaican clinicians for the assessment of child behavior problems and subjected these to principal components analyses. Regardless of whether the sample was split according to age or sex, the analyses revealed factors similar to the Over- and Undercontrolled syndromes most often found in other cultures. The analyses also revealed school absence factors in each age and sex group; school avoidance was correlated with crying in children (aged 6–11) but with conduct problems in adolescents (aged 12–17). The findings suggest important similarities and possible differences between the factor structures of child behavior problems in Jamaica and the United States.This study was supported through grants from the University Research Council of the University of North Carolina at Chapel Hill and Sigma Xi, the Scientific Research Society, which we gratefully acknowledge.

Right hemisphere language ability: 1. Clinical evidence

Evidence from a variety of clinical sources concerning the nature of language processing ability within the right cerebral hemisphere (RH) is reviewed. It appears that the RH is severely deficient with respect to the expressive functions of speech and writing, but it may possess a significant ability to comprehend language. It has been suggested that the ability of the RH in this respect may be extensive, but the generality of conclusions drawn seems to be suspect. Evidence from patients with left hemisphere damage suggests that in some circumstances the RH may ‘take over’ the performance of language functions from its inoperative partner. Further work should help clarify the conditions under which this takes place. The theory that reading in deep dyslexia is mediated by the RH is also reviewed. The idea that the RH is able to encode print stimuli into semantic but not phonological representations, and the possibility that it is selectively able to process imageable nouns, are two aspects of this theory that are consistent with other sources of evidence concerning RH language ability. However, support for the theory is far from unanimous, and the contradictory evidence is noted.     

Hand position as a variable determining the accuracy of aiming movements

Two experiments investigated the effect of hand position on the accuracy of short- and long-duration aiming movements in the presence and absence of visual feedback. In Experiment 1 (N = 16) short aiming movements were executed rapidly, which would require them to be predominantly programmed, whereas in Experiment 2(N = 8) these movements were performed slowly enough so that visual feedback, which implies that they were predominantly programmed. However, the long-duration, short-length movements of Experiment 2 were disrupted when visual feedback was removed, which suggests that these movements were being guided by visual feedback. Having the heel of the responding hand in contact with the target platform during the response resulted in greater accuracy than no hand contact for the short-length movements of both experiments. Taken together, these results indicated that hand contact produced greater aiming accuracy than no hand contact for both programmed- and feedback-based movements.
