RETEST EFFECTS ON IDENTICAL AND PARALLEL FORMS IN CERTIFICATION AND LICENSURE TESTING

Examinees who take credentialing tests and other types of high-stakes assessments are usually provided an opportunity to repeat the test if they are unsuccessful on initial attempts. To prevent examinees from obtaining unfair score increases by memorizing the content of specific test items, testing agencies usually assign an alternate form to repeat examinees. Given that the use of multiple forms presents both practical and psychometric challenges, it is important to determine if unwarranted score gains occur. Most research indicates that repeat examinees realize score gains when taking the same form twice; however, the research is far from conclusive, particularly within the context of credentialing. For the present investigations, two samples of repeat examinees were randomly assigned to receive either the same test form or a different, but parallel, form on the second occasion. Study 1 found score gains of about 0.79 SD units for 71 examinees who repeated a certification examination in computed tomography. Study 2 found gains of 0.48 SD units for 765 examinees who repeated a radiography certification examination. In both studies score gains for examinees receiving the parallel test were nearly indistinguishable from score gains for those who received the same test. Factors are identified that may influence the generalizability of these findings to other assessment contexts.     

AVERY DULLES,TEACHING AUTHORITY IN THE CHURCH,AND THE ‘DIALECTICALLY TENSE’ MIDDLE: AN AMERICAN STRATEGIC THEOLOGY

Father Dulles is now largely thought by friend and foe alike to be one of the most forceful voices for a renewed orthodoxy in the Church. Liberals see him as having turned his back on his younger radicalism; like many an older man, they suggest, he has grown more conservative with age. His experiences with certain forms of liberal Catholicism, while not changing his ideas about the Church, seemed to have alerted him to their potential for disaster. 1     

THE EFFECT OF TELEVISION AND RADIO ON CHILDREN'S CREATIVITY

The literature on creativity posits that creative abilities are stable and relatively impervious to short-term interventions. Several studies have, however, reported differential effects of media on children's imaginative play and thinking. The results of these studies are difficult to interpret owing to their reliance on nonstandardized measures of creativity. The present study examines the relative effects of television versus radio on children's creativity. Third and sixth graders were presented a story on television or radio and were then given an adapted version of the “Just Suppose” test of divergent thinking developed by Torrance (1974). Responses were scored in terms of ideational fluency, flexibility, and originality. The results indicated that the two media did not have a differential effect on children's creativity.     

ANALYZING UTTERANCES AS THE OBSERVATIONAL UNIT

If utterances are the observational unit of analysis and there are no sequential patterns to the interaction, two alternative statistical models may be applied. A hierarchical design in which utterances are nested within subjects and subjects are nested within treatment condition is considered. One method of analysis pools utterances within treatment condition; the other method collapses across utterances to obtain subject means. Inappropriate application of the pooling model instead of the subject means model can lead to Type I errors, decreased generalizability, and inflated variance estimates that attenuate univariate and multivariate correlations. The effect of utterance reliability on the apparent unidimensionality and parallelism of multiple indicators is also discussed.     

The Impact of Negative Campaign Ads

We compared negative and positive ads in the context of a fictitious election. Participants read a strong or weak message supporting one candidate (positive ad) or derogating the opposition candidate (negative ad). The strong positive message had a greater impact on attitudes toward the candidates than the weak positive message, but message strength had no significant effect for negative messages, suggesting that positive messages are centrally processed, and negative messages serve mainly as peripheral cues. Accordingly, a strong positive message was more effective than a weak positive message, but a weak positive message was less effective than a weak negative message. We conclude that negative political ads are advisable only when candidates cannot provide strong arguments to support their candidacy.     

Exploring the Effects of the Naturalistic Fallacy: Evidence That Genetic Explanations Increase the Acceptability of Killing and Male Promiscuity

The naturalistic fallacy is the erroneous belief that what is natural is morally acceptable. Two studies assessed whether people commit the naturalistic fallacy by testing whether genetic explanations for killing and male promiscuity, as compared to experiential explanations (i.e., learning/“nurture” explanations) increase acceptance of these behaviors. In Study 1, participants who read a genetic explanation for why people kill bugs viewed bug killing as more morally acceptable than participants who read an experiential explanation, although they did not reliably kill more bugs. In Study 2, men who read a genetic explanation for why men are more promiscuous than women reported decreased interest in long‐term romantic commitment compared with men who read experiential explanations and women who read either explanation.
