The Role of Individual Differences and External Variables in a Test of the Sufficiency of Fishbein's Model to Explain Behavioral Intentions to Conserve Water

The sufficiency of fishbein's attitude model was tested with respect to behavioral intentions to conserve water. Regression analysis showed subjective norms (SN) to be the variable most highly correlated with intentions. It was also found that, contrary to the model, SN and evaluative attitudes (Aact) did not adequately mediate all the variation in intentions accounted for by the variables included in this analysis. Age was found to be an important external variable in explaining water conservation intentions, The equations of the models which predict SN and Aact were also analvzed. Analysis of regressions for dichotomized groups revealed strong individual differences in regression equations. Age, along with SN and Aact, was found to be an important variable in accounting for individual differences. The findings are discussed in relation to the sufficiency of Fishbein's model and the role of individual differences in Understanding water conservation intentions.     

Problem-solving performance of young boys and girls as a function of task appropriateness and sex identity

The problem-solving performance of young boys and girls was examined in three conditions in which good performance was indicated as being appropriate for boys, for girls, or for both boys and girls. The relations between task scores and five sex-role measures were also examined. As predicted, the boys performed significantly more poorly when the task was indicated as one that girls did better. The girls' performance was not affected by the conditions of the study. The girls' problem-solving scores did not differ significantly from the boys' scores. There was some relationship between the task scores and the sex-role measures for boys, but not for girls. Associations among the sex-role measures were not high.This research was supported by a DGES-FCAC research grant from the government of Quebec, Canada.     

Measures of interobserver agreement: Calculation formulas and distribution effects

Seventeen measures of association for observer reliability (interobserver agreement) are reviewed and computational formulas are given in a common notational system. An empirical comparison of 10 of these measures is made over a range of potential reliability check results. The effects on percentage and correlational measures of occurrence frequency, error frequency, and error distribution are examined. The question of which is the best measure of interobserver agreement is discussed in terms of critical issues to be considered     

Effect of communication discrepancy and ambiguity on placement and opinion shift

Analyzed social judgment theory of attitude change and studied placement of a communication and opinion shift in an experiment on visual perception. In a 3 × 3 design plus a control group, 110 undergraduate college students (50 men and 60 women) received a communication after estimating the number of dots on 14 slides. The communication varied at three levels of ambiguity and three levels of discrepancy. Ss gave estimates of the communication from memory (measuring assimilation) and gave a second set of their own estimates (measuring opinion shift). Assimilation varies directly with ambiguity (p < .00l) but is unrelated to discrepancy. Opinion shift varies significantly as a function of discrepancy (p < .00l) but is unrelated to ambiguity. Authors hypothesize assimilation and opinion change may be negatively correlated at small discrepancies but directly correlated at large discrepancies.     

Identification,localization, and “iconic memory”: An evaluation of the bar-probe task

The partial report tachistoscopic task has been used to define “iconic memory,” a labile image-like precategorical visual store. Six interrelated partial report studies are reported that challenge the construct. On each trial, subjects were shown an eight-letter pseudoword (representing one of four orders of approximation to English) and a bar probe indicating which letter to report. The probe was delayed systematically, and the experiments included both mask and no-mask conditions. All three variables-familiarity of the material, masking, and delay of the probe-affected accuracy of report. Delaying the probe, for example, reduced accuracy by increasing location errors. Delaying the mask increased accuracy by reducing both location and item errors, but it did not reduce the location errors until its effect on item errors had reached asymptote. Across the stimulus array, however, masking reduced accuracy at all delays by increasing location errors. Finally, the greater accuracy associated with higher orders of approximation to English was complemented by a decrease in item errors, but the familiarity factor had no effect on location errors. Taken together, even though the task has been used to define the idea, the results indicate that the bar-probe task cannot be explained in terms of a simple iconic memory concept. Instead of a simple image-like buffer, the explanation requires a feature buffer, an “intelligent” letter identification process, and a postidentification character buffer. Iconic memory is a construct that oversimplifies the information processing system used in the bar-probe task.     

Nutritional misinformation of children: A developmental and experimental analysis of the effects of televised food commercials

This study assessed the accuracy of judgments of 100 school age children as to the presence of real fruit content in 3 sets of cereals and beverages advertised on TV: real fruit, nonfruit, and artificially fruit flavored products. In the baseline session, accuracy was an increasing function of age, but children at each age were deceived about real fruit content of artificial fruit products. In session 2, the experimental group saw TV ads for 6 products embedded in a program (naturalistic viewing). They then judged fruit content for these six advertised products, plus a matched set of six for which ads were not shown. Controls saw toy ads on TV, and then judged the same 12 products. In session 3, subjects in each group saw the same ads they had seen in Session 2, without the program and with instruction to attend very carefully to messages in the ad (intensive viewing). They then judged all 12 products again. After naturalistic viewing, few significant differential changes from baseline were found. But after intensive viewing, accuracy of judgment of advertised artificial fruit products was lower than baseline among experimental group children. By contrast, accuracy was higher than baseline both for control children's judgements of “advertised” prod-     

Relationship among environmental and demographic variables and teacher-rated hyperactivity

This study assessed the role of environmental and demographic factors in the occurrence of teacher-rated hyperactivity. The subject group consisted of 79 hyperactive and 81 nonhyperactive children ranging from 5 to 12 years of age. Parents of the subjects were interviewed to obtain information regarding the environmental and demographic factors of sex, race, birth order, number of siblings, frequency of change of residence, income level, mother's age, father's age, educational level of mother, educational level of father, parents' marital status, and the method of child discipline used in the home. Comparison between the hyperactive and nonhyperactive groups suggested nonsignificant differences with the exception of sex (p<.001), in which the ratio of hyperactive males to hyperactive females was 51.The authors are grateful to Dr. Bruce Dunn for his critical suggestions.     

The Vocational Interests of Beautiful Women

This paper reports the analysis of Strong Vocational Interest Blank scores for about 100 fashion models. Their interest patterns reflect preferences for the dramatic over the routine, the unstructured situation over the structured. These girls favor verbal occupations, and show particular aversion toward working with numbers in precise, disciplined settings. They are pretty, they know it, and they prefer activities that permit them to take advantage of their attractiveness.
