Humor as a negatively accelerated function of the degree of incongruity

The method of limits with weights was employed to determine whether a positive or inverted-U relation described the function between the degree of incongruity and indicators of humor. The degree of incongruity was defined as the difference between the mean of six previous Comparisons and a seventh heavier Comparison ranging from 250 to 7040 grams. Facial expressions and humor and surprise ratings to the seventh Comparison increased in a negatively accelerated fashion with the degree of incongruity. Downward trends in humor indicators with increased incongruity did not occur, and thus the inverted-U relation was not supported. Studies finding an inverted-U relation were interpreted as being the result of the incongruous stimulus coming from another dimension rather than from within the same dimension as the internal standard.     

Humor appreciation as a function of sexual,aggressive, and sexist content

The purpose of the present investigation was to examine the relationship between the rated sex, aggression, and sexism values of cartoons with their rated funniness values. Multiple regression analyses indicated that for women, only sexism values correlated with cartoon funniness, albeit negatively. For men, however, only sex values correlated (positively) with cartoon funniness. The results were interpreted by Zillmann's social predisposition theory. Women, more likely having been victims of sex discrimination, identified with the cartoon victim and thus found sexist cartoons less funny. Men, because of their social history, made no such identification and were more aware of the sexual aspects of the cartoons. This influenced their funniness ratings of the cartoons, which replicated previous research.     

Changing food preference as a function of mood

The authors investigated the effect of mood on food selection. Participants (N = 98) indicated the likelihood of general eating and the likelihood of eating specific foods after reading and projecting themselves onto the events and emotions described in a sad and a happy vignette. Both men and women believed they were more likely to consume food following a happy versus a sad event, and men believed they were significantly more likely to eat than did women. However, the type of food men and women believed they would consume interacted with the type of event experienced. Vegetarian snack foods were more likely to be consumed following a happy versus a sad event, with men more likely to eat snack foods. Men did not significantly change in likelihood of consuming sweet foods as their mood changed. However, women believed they were more likely to consume sweet foods following a sad event. The authors discuss the results in terms of a self-medication hypothesis and the effect of carbohydrates on central serotonin and endogenous opioids. Overall, results demonstrated that mood influences belief in the likelihood of food selection.     

Autoshaping as a function of prior food presentations

Young chickens were given 1, 10, 100, or 1000 presentations of grain in a hopper. Subsequently, the key was illuminated before each presentation of grain to study autoshaping of the key-peck response. The number of keylight-grain pairings before a bird first pecked the lighted key was found to be a U-shaped function of the number of prior food-only presentations, with pecks occurring significantly sooner after 100 food-only trials than after any of the other values. Two of five chicks at the 100-trial value pecked on the first illumination of the key. Experiment II showed further that when a series of food-only trials (no keylight) preceded keylight-only trials (no food) 30% of the chicks pecked the illuminated key. Experiment III extended the generality of first-trial pecking to pigeons. After preliminary training with food-only, two of five pigeons pecked on the first illumination of a key. The results suggest a close relationship between autoshaping and pseudo-conditioning.     

Response to cigarette deprivation as a function of oral fantasy.

The role of oral fantasy in reactions of heavy smokers to smoking deprivation was studied. Experimental subjects were first evaluated with the Holtzman Inkblot Test to measure amount of oral fantasy. They also evaluated themselves on a number of Semantic Differential continua. Smoking deprivation followed. Retest Holtzman blots and Semantic Differential rating scales were then administered. Subjects also indicated number of somatic symptoms and body image distortions produced by deprivation. Control subjects followed the same paradigm except they smoked throughout the procedure. It was found that the greater the orality of experimental subjects the greater the number of somatic symptoms and body distortions they experienced following deprivation; and the more they viewed self as having shifted in a less favorable and less potent direction. Such relationships were absent in the control group.
