The effectiveness of visual and gustatory conditioned stimuli in human classical aversive conditioning with electric shock

Thirty-six undergraduate volunteers, divided into three equal groups, were given electric shock while sipping a colored, unflavored solution (Group I): a flavored, colorless solution (Group 2); or a colored, flavored solution (Group 3), in order to determine whether human Ss respond differentially to visual and gustatory cues when the UCS is aversive electric shock. Using a standard classical discrimination procedure, the CS + was blue water for Group 1, citric acid solution for Group 2, and blue citric acid solution for Group 3. For all groups the CS- was plain water, which was never paired with electric shock. The dependent variables were derived from Staats' A-R-D theory: attitudinal change (A) and a performance measure of sip-size taken during conditioning trials (D) both confirmed the hypothesis that taste can be an effective CS when the UCS is shock, in contrast to results typically obtained with rats where visual but not taste cues are effective with a shock UCS.     

Cognitive and motivational determinants of children's humor responses

Cognitive and motivational influences on children's humor responses were examined. Forty-eight Caucasian children from three economically heterogeneous schools were tested. Equal numbers of middle SES and lower SES boys and girls from kindergarten and third grade were shown 12 aggression and dependency cartoons of different difficulty levels. Three responses to each cartoon were recorded: mirth, funniness rating, and comprehension score. Results support aspects of both psychodynamic and cognitive theories of humor response. All children preferred aggressive themes to dependency themes, and third graders especially showed attenuated response to dependency cartoons. Funniness ratings decreased as difficulty levels increased. IQ, as assessed by the Peabody Picture Vocabulary Test-R, was positively related to humor. Mirth responses and funniness ratings increased as comprehension increased.     

Is it just reading?: Comments on the papers by Mann,Morrison, and Wolford and Fowler

Comments on the stimulating papers by V. A. Mann (Reading skill and language skill. Developmental Review, 1984, 4, 1–15), F. Morrison (Reading disability: A problem in rule learning and word decoding. Developmental Review, 1984, 4, 36–47), and G. Wolford and C. A. Fowler (Differential use of partial information by good and poor readers. Developmental Review, 1984, 4, 16–35) come under four headings. First, their differences with respect to the organizing themes are identified. Second, the central difficulty, for theories of reading disability, posed by the high correlation between reading and IQ, and ways of dealing with this difficulty, are discussed. In the third and fourth sections, comments on the individual papers and a summary of the main lessons to be learned from this collection are presented.     

A developmental study of semantic elaboration and interpretation in recognition memory

Two experiments examined semantic elaboration and interpretation in recognition memory of 4-year-olds and college students. Subjects were presented pictures of color-specific and non-color-specific items, and then tested for their recognition of the chroma of the items. In Experiment 1, one-half of the presentation items were black and white and one-half colored, and testing always involved one black and white and one colored choice. In Experiment 2, all of the presentation items were colored, and testing always involved two colored choices. In both studies, the pattern of results of the two age groups was similar. Experiments 1 and 2 indicated that recognition judgments were based on representations that were elaborated with preexperimentally acquired semantic color information, and Experiment 2 also indicated that recognition judgments were based on representations that contained interpretive information about the appropriateness of the colors of the items. The results were considered to support and extend the view that when young children and adults share a common knowledge base, they are likely to engage in similar and extensive semantic processing.     

Variables affecting preference for signaled shock in a symmetrical changeover design

In a signaled-shock situation, the signal's presence serves a warning function (prediction of shock) whereas the signal's absence serves a safety function (prediction of nonshock periods). The relative contribution to preference for signaled shock made by these two potential sources of reinforcement was assessed using a symmetrical changeover procedure in which rats were permitted to control the amount of time spent in one of two mutually exclusive conditions, the signaled and unsignaled states. The stimulus conditions that prevailed in the signaled state differed for several groups of animals. For some groups, the safety function of signals was degraded while the warning function was left intact. For other groups, the warning function was degraded and the safety function was not. The availability of the unaltered feature was then manipulated in both sets of groups to determine its effect on preference for the signaled state. Changeover behavior was strongly related to the availability of the signal's safety function and weakly related to its warning function, indicating that the two variables contribute differentially to preference for signaled shock. Other sources of behavioral control, having little to do with the safety or the warning function of signals, were also demonstrated, suggesting the need for careful control procedures when using changeover behavior as a measure of preference.     

The fit between Strong-Campbell Interest Inventory General Occupational Themes and Holland's hexagonal model

Using a multidimensional scaling procedure, the present study examined the fit of Holland's RIASEC hexagon model to the internal relationships among the Strong-Campbell Interest Inventory (SCII) General Occupational Theme scales. SCII intercorrelation matrices for both sexes as reported in the SCII Manual were submitted, separately for each sex, to TORSCA 9 nonmetric scaling analysis. The Wakefield and Doughtie procedure was used to compare obtained TORSCA coordinates with expectations from Holland's hexagonal model. As a comparison, identical analyses were performed on Vocational Preference Inventory (VPI) scale intercorrelation matrices, these data having originally served as the basis for advancing the utility of the hexagon model. For females, the SCII-hexagon fit was not good, with a near reversal of the Social and Enterprising scales. For males, the SCII-hexagon fit was good. For either SCII or VPI scales, the female data met expectations from Holland's model less often than the male data. A replication study on SCII data for 305 female clients of a vocational assessment clinic confirmed the previously observed sex differences. Sex differences in the structure of vocational preferences are discussed.     

The impact of education and selected traits on sex-role related goals and attitudes

Questionnaires that assessed educational goals, career goals, preferred and expected career commitment, sex-role attitudes, age, college class, height, and weight were completed by 884 male and female undergraduates representing two racial groups and two age groups. Age, size, and college class were unrelated to women's goals and attitudes, whereas men chose more traditional careers as their education progressed. Technical college students tended to be more traditional than university students. Implications for related research are discussed.
