UNDERSTANDING THE IMPACT OF TEST VALIDITY AND BIAS ON SELECTION ERRORS AND ADVERSE IMPACT IN HUMAN RESOURCE SELECTION

We propose an integrative framework for understanding the relationship among 4 closely related issues in human resource (HR) selection: test validity, test bias, selection errors, and adverse impact. One byproduct of our integrative approach is the concept of a previously undocumented source of selection errors we call bias‐based selection errors (i.e., errors that arise from using a biased test as if it were unbiased). Our integrative framework provides researchers and practitioners with a unique tool that generates numerical answers to questions such as the following: What are the anticipated consequences for bias‐based selection errors of various degrees of test validity and test bias? What are the anticipated consequences for adverse impact of various degrees of test validity and test bias? From a theory point of view, our framework provides a more complete picture of the selection process by integrating 4 key concepts that have not been examined simultaneously thus far. From a practical point of view, our framework provides test developers, employers, and policy makers a broader perspective and new insights regarding practical consequences associated with various selection systems that vary on their degree of validity and bias. We present a computer program available online to perform all needed calculations.     

Overweight and cognition

There is a growing concern among health authorities that an increasing number of people in the Western world become overweight and even obese. It is well known that obesity is related to several diseases (e.g., diabetes, stroke, and high blood pressure) and that such diseases related to obesity lead to early death. It has also been discussed whether overweight and obesity in themselves or in relation to such diseases lead to cognitive decline. On the basis of data from a large, population‐based, prospective study we examined three cognitive domains: episodic memory, semantic memory, and spatial ability. Two body measures were used to define normal weight and overweight, body‐mass index and waist/hip ratio. Although these two body measures reveal quite different prevalence data of overweight, the associations between overweight and cognition are similar. For episodic memory, overweight interacts with age, but when controlling for hypertension, stroke and diabetes, this interaction disappears. For semantic memory, normal weight participants outperform overweight participants even after controlling for these diseases. For spatial ability, the well‐established advantage for men holds for young‐old and old‐old normal‐weight participants. For overweight participants, this advantage holds for middle‐age participants only. We conclude that there is a weight‐cognition relationship even after controlling for obesity‐related diseases. The results are discussed in terms of possible biological mechanisms.     

INDIVIDUAL DIFFERENCES IN INTERVIEWER RATINGS: THE IMPACT OF STANDARDIZATION, CONSENSUS DISCUSSION, AND SAMPLING ERROR ON THE VALIDITY OF A STRUCTURED INTERVIEW

This research investigated empirical issues regarding the validity of individual interviewers'( N = 62) ratings collected after a structured interview. Each interviewer rated an average of 25 interviewees. One hypothesis examined but not supported was that systematic interviewer errors will attenuate interview validity when data are aggregated across interviewers. Also investigated was the validity of ratings averaged across interviewers compared to consensus ratings; consensus ratings were shown to have significantly but probably not practically higher validities. Third, a meta-analysis of individual interviewer validities revealed that all of the variance in validities could be attributed to sampling error. Results and implications are discussed.     

Analyzing Ethical Conflict in the Transracial Adoption Debate: Three Conflicts Involving Community

This essay explores ethical conflicts underlying the discourse of the policy debate about transracial adoption, focusing on the adoption of Black children by whites. Three underlying conflicts are analyzed, namely, the values of equality versus community, interracial community versus mukiculturalism, individuality versus racial-ethnic community. The essay concludes with observations on multicultural families.     

Downsizing: Case Study of a Career in Crisis

Downsizing is a major concern in American industry today. Although much has been written about the effects of downsizing on corporations, little has been said about its effect on individuals. This case presents downsizing from one individual's perspective and suggests strategies and procedures for reducing the negative effect of downsizing on employees. Strategies and procedures that firms can adopt to make downsizing programs effective include planning in advance, developing effective communications, centralizing decision making, and educating personnel specialists and managers.     

To drive or not to drive: Neuropsychological assessment for driver's license among stroke patients

Seventy-two stroke patients, 43 with right hemisphere (RHD) and 29 with left hemisphere damage (LHD), and 7 coronary infarct controls with no evidence of cerebral damage, were neuropsychologically tested as part of an assessment program for driver's license. Mean age in the group was 53 years. Stroke patients were tested on average 4 months post injury. The groups did not differ on major demographic variables except that RHD patients were more often hemiplegic than LHD patients. The test battery was factor analyzed into 4 valid principal components: (I) visual perception , (II) spatial attention , (III) visuospatial processing , and (IV) language/praxis. The presence of hemianopia (factor I) excludes driving. In addition, measures of neglect and reduced speed of mental processing from factor II, III and IV, were found to be the most discriminating variables when classifying patients for driving. Even though neglect was more frequently observed among RHD than LHD patients, the two hemisphere groups did not differ significantly in number of patients denied driving, 58% RHD compared to 41% LHD patients. The need for comprehensive neuropsychological assessment is underlined.     

Dissociative effects of elaboration on memory of enacted and non-enacted events: A case of a negative effect

One experiment compared the effect of elaboration on enacted and non-enacted events. The commands were either presented in a basic form (e.g., "wave your hands") or in an enriched form. The commands were enriched by adding statements to the commands of how to perform the actions (e.g., "wave your hands as a conductor"). Free- and cued-recall data showed elaboration to have a dissociative effect on enacted and non-enacted events. Memory for the non-enacted events benefited from enrichment, whereas simple enacted events were remembered to a higher extent than complex enacted events. Lack of benefit from elaboration on memory of enacted events is suggested to be due to enactment leading to a sufficient degree of item-specific processing, and a negative effect of elaboration is suggested to occur when the way of manipulating item complexity decreases the familiarity of the actions. Familiarity ratings of the items by two independent groups of subjects supported this interpretation.     

Psycho-Palliation and the Enlightened Counselor

The counseling process of psycho-palliation is presented as a type of spiritual journey that leads to enlightenment. First, the theory of psycho-palliation is defined. Then, a step-by-step outline is given on how a psycho-palliative attitude produces enlightenment for the counselor. Throughout the exposition, the theory of psycho-palliative counseling is expanded upon through the use of parables and spiritual references from the world's religions. Wosong had learned much and thought that he was ready to enter Heaven. So he went to the doors of Heaven and knocked. A voice said, “Who is there?” “It is Wosong, and I am ready to enter.” The voice replied, “I am sorry Wosong, but there is not room for me and thee.” Dejected, Wosong returned to his place, studied all the prophets and gave all he had to the poor. Once again he returned to the doors of Heaven and knocked. A voice said, “Who is there?” “It is Wosong.” The voice replied, “I am sorry Wosong, but there is not room for me and thee.” In complete confusion, Wosong returned to his place. For 7 years, he meditated on the voice of Heaven. Then, in complete humility, he knocked on the doors of Heaven. A voice said, “Who is there?” Wosong replied, “It is thyself.” So the voice said, “Enter. I always have room for myself.”
