Measuring Procedural Knowledge More Simply with a Single-Response Situational Judgment Test

Purpose  This paper describes the development of a situational judgment test (SJT) based on single-response options developed directly from critical incidents and reports a study that tested the SJT’s concurrent validity against ratings of job performance. Design/Methodology/Approach  Situational judgment test items were developed from critical incidents provided by administrators of volunteer agencies. Volunteers who worked at another agency completed the SJT and a self-report personality test. Supervisors rated their job performance on three dimensions. Findings  Situational judgment test scores representing procedural knowledge about work effort were significantly correlated with ratings of work effort performance (r = .28). Conscientiousness was correlated with work effort knowledge (r = .26), but not with work effort performance (r = −.02). Implications  These results provide some preliminary evidence that a single-response SJT format based upon critical incidents can produce valid measures of procedural knowledge and might be a useful alternative to the traditional multiple-response format. Originality/Value  This paper presents a novel way to construct SJTs using single-response options that are less laborious to develop than the multiple-response options in traditional SJT formats. Results of the validity study suggest that this new single-response format can predict job performance and encourage further research on the viability of this approach.     

The Multidimensional Media Influence Scale: Confirmatory factor structure and relationship with body dissatisfaction among African American and Anglo American children

The Multidimensional Media Influence Scale (MMIS; Cusumano & Thompson, 2001). Media influence and body image in 8–11-year-old boys and girls: A preliminary report on the multidimensional media influence scale. International Journal of Eating Disorders, 29, 37–44) is a child-appropriate, 3-factor scale designed to assess perceived media influence on body image. It has been used in studies exploring the relationship between the entire scale as well as its subscales (awareness, internalization, and pressure) and variables related to body image. However, the 3-factor structure of the scale has never been confirmed via confirmatory factor analysis (CFA), nor has the scale been evaluated with a racially diverse sample of children. This paper reports the results of CFAs establishing the multidimensionality of the scale and the unidimensionality of its subscales among a sample of 661 girls and boys aged 7–12 years, primarily African American and Anglo American. The pressure factor of the MMIS predicted the idealization of a thinner current (child) and future (adult) body both cross-sectionally and one year later for girls and for Anglo American children.     

The representative animal

The anthropocentric approach to the study of animal behavior uses representative nonhuman animals to understand human behavior. This approach raises problems concerning the comparison of the behavior of two different species. The datum of behavior analysis is the behavior of humans and representative animal phenotypes. The behavioral phenotype is the product of the ontogeny and phylogeny of each species, and this requires that contributions of genotype as well as behavioral history to experimental performance be considered. Behavior analysis tends to favor the ontogenetic over the phylogenetic component, yet both components are responsible for the performance of each individual animal. This paper raises questions about the role of genotype variables in the use of representative animals to understand human behavior. Examples indicating the role of genotype in human behavior are also discussed. The final section of the paper deals with considerations of genotype in the design of animal experiments.     

A visual approach to statistical power analysis on the microcomputer

Computer programs for statistical power analysis typically require the user to provide a series of values and respond by reporting the corresponding power. These programs provide essentially the same functions as a published text, albeit in a more convenient form. In this paper, we describe a program that instead uses innovative graphic techniques to provide insight into the interaction among the factors that determine power. For example, fort tests, the means and standard deviations of the two distributions, sample sizes, and alpha are displayed as bar graphs. As the researcher modifies these values, the corresponding values of beta (also displayed as a bar graph) and power are updated and displayed immediately. By displaying all of the factors that are instrumental in determining power, the program ensures that each will be addressed By allowing the user to determine the impact that any modifications will have on power, the program encourages an appropriate balance between alpha and beta while working within the constraints imposed by a limited sample size. The program also allows the user to generate tables and graphs to document the impact of the various factors on power. In addition, the program enables the user to run on-screen Monte Carlo simulations to demonstrate the importance of adequate statistical power, and as such, it can serve as a unique educational tool.     

Verbal accounts and attributions of social motives

The effects of verbal accounts offered by a threatener on targets' subsequent attributions of the threatener's social motives was studied. Following a standardized interaction in a Prisoner's Dilemma game the subjects' opponent offered one of three accounts for using threats: cooperative intent, establishment of transrelational equity, or ignorance. In a fourth condition the confederate offered no account for his actions. Attributions were assessed by having subjects rate each of four responses representative of the social motives of cooperation, competition, apathy, and deceit in five different situations. It was found that the type of account had specific attributional effects. A cooperative account led to a correspondent inference of a cooperative disposition, a transrelational equity account was apparently perceived as illegitimate and led to an attribution of a deceitful motive, and an excuse of ignorance was linked with apathy.
