Strategic and tactical limits of comparison studies

A comparison study is an experiment whose primary purpose is to compare directly (regardless of experimental design) at least two different procedures for changing behavior or two or more components of such a procedure. This paper argues that, in spite of their popularity, such studies typically lead to inappropriate inferences with poor generality based on improper evidence gathered in support of the wrong question, thus wasting the limited experimental resources. The discussion considers problems concerning the functions of comparison studies, the nature of the comparisons that are attempted, the generality of their findings, and the limited role that they can play in technological research.     

Reliability of parental reports using the Katz Adjustment Scales: before and after hospital admission for schizophrenia

We examined the interrater and test-retest reliability of the KATZ Adjustment Scale (Relative rated or R form) longitudinally in a sample of schizophrenic patients, assessing their function before hospital admission, as well as at 1 and 9 mo. after discharge. Changes in mean scores over those assessments suggested sensitivity to change while mothers and fathers both completed the measure with moderate consistency over time. Interrater reliability was moderate at best and quite poor at initial testing, when the subjects were most disturbed clinically, suggesting that the scales may be acceptable when the individual is stable but that ratings may be unreliable when there is an exacerbation in clinical state.     

Is dependence on phonological information in children's reading a product of instructional approach?

Eight-year-old British children were found to be less accurate at rejecting pseudohomophones than ordinary nonwords in a lexical decision task, but 8-year-old New Zealand children did not show this effect. A subsequent homophone decision task showed that this difference was not due to the New Zealand children being unable to distinguish pseudohomophones from other nonwords. The New Zealand children, however, were less accurate than the British children in pronouncing the pseudohomophones they had identified. It was argued that the British children tended to sound out the items before making a choice in the lexical decision task, which gave salience to phonological rather than visual information, resulting in increased errors to the pseudohomophones. It was concluded that where the British children showed this dependency on use of phonological information it was a product of the teaching approach they had experienced.     

Levels of selection and capacity limits

Subjects performed a visual target-detection task in eight experiments. We examined the effects of word relevancy (word in relevant or irrelevant location) and display load (1-4 words) on physical, semantic, and controlled processing of nontargets. Interwoven with the detection task was a test-word identification task that was used to measure priming potency of nontargets. Physical and semantic levels of processing were measured in terms of identity and semantic priming, respectively. Nontarget primes were repeated as test words in identity priming. Nontarget primes were semantic associates of test words in semantic priming. Controlled processing of nontargets was measured in terms of recognition memory on a subsequent test. All measures increased with word relevancy and decreased with display load. The priming effects remained intact even when word presentation was speeded up and controlled processing was sharply curtailed. The data indicate that all levels of processing are selective and capacity limited.     

Why do males and females differ? Children's beliefs about sex differences

The present paper focuses on children's beliefs about sex differences and how these are related to age and gender. Seven, ten, and fifteen year olds (N=427) were asked to give explanations for their beliefs about sex differences. In strong agreement with previous research and the cognitive-developmental theoretical framework, marked age differences were found: younger children were more likely than older children to emphasize biological and physical factors. Significant gender differences were also found, especially for 15 year olds. Girls were much more likely to attribute sex differences to social factors, and boys to biological factors. These gender differences were interpreted as being indicative of different life experiences of males and females, with females being more likely to have experienced conflicts between their own values about sex-role behavior and those of society. Findings were also interpreted as being consistent with the recent emphasis on gender schema. Nevertheless, it was argued that theories of gender schema need to take more account of content—of the beliefs that people hold about sex roles—and, in particular, that more attention be given to exploring gender differences in beliefs.     

Expanding the Horizontal Call: A Typology of Social Influence on the Call to Ministry

This research examines the social actors and interactions that facilitate seminary students' sense of calling. Drawing from 36 in-depth interviews with first year Masters of Divinity students, we introduce six ideal typical social others who play a formative role in the early stages of a call to ministry: instigators, exemplars, interpreters, affirmers, challengers, and codiscerners. Together, these findings demonstrate that the call to ministry, while deeply personal, emerges through social interactions that facilitate and make plausible a person's sense of calling and that sustain it over time. Extending Richard Pitt's conceptualization of the “horizontal call,” this paper argues that social others help evoke and solidify—not merely legitimate—a personal sense of call. This research also highlights differences in the social structuring of call by gender. Despite considerable gains in the ordination of women, we find that many still face obstacles to experiencing and embracing a call to ministry.
