Unconscious priming according to multiple S-R rules

The present study investigated if unconscious primes can be processed according to different stimulus-response (S-R) rules simultaneously. Participants performed two different S-R rules, such as judging a digit as smaller or larger than five and judging a letter as vowel or consonant. These S-R rules were administered in random order and announced by a previously presented cue. Each target stimulus was preceded by subliminal primes which afforded a different or an identical response according to either the currently irrelevant or currently relevant S-R rule. In three experiments, we consistently found priming effects according to currently irrelevant S-R rules, even when primes for the relevant and irrelevant S-R rules were presented simultaneously. Thus, unconscious stimuli have the power to activate responses according to currently required and currently not required S-R rules concurrently. The results are in line with response activation accounts of subliminal priming and suggest that at least two routes may gain access on response processes simultaneously.     

Combining predictors to achieve optimal trade-offs between selection quality and adverse impact

The authors propose a procedure to determine (a) predictor composites that result in a Pareto-optimal trade-off between the often competing goals in personnel selection of quality and adverse impact and (b) the relative importance of the quality and impact objectives that correspond to each of these trade-offs. They also investigated whether the obtained Pareto-optimal composites continue to perform well under variability of the selection parameters that characterize the intended selection decision. The results of this investigation indicate that this is indeed the case. The authors suggest that the procedure be used as one of a number of potential strategies for addressing the quality-adverse impact problem in settings where estimates of the selection parameters (e.g., validity estimates, predictor intercorrelations, subgroup mean differences on the predictors and criteria) are available from either a local validation study or meta-analytic research.     

A Practical Procedure to Estimate the Quality and the Adverse Impact of Single–Stage Selection Decisions

The quandary posed by the conflicting goals of valid selection and a diverse workforce is one of the most perplexing problems facing the practice of personnel selection today. To help address the issue, the article presents a comprehensive method and a related computer program to estimate the expected adverse impact and the expected quality of the majority, the minority and the total selected work force. Compared to previous related procedures, the present method is much more general as it can address situations with both multiple predictor and multiple criterion dimensions. In addition, the expected effects can be computed given the overall selection ratio and the estimates are derived analytically and, hence, are accurate. To assist the selection practitioner, the method is made available as a free download from the Internet.     

Pareto‐Optimal Predictor Composite Formation: A complementary approach to alleviating the selection quality/adverse impact dilemma

In our rejoinder to the comments of Kehoe (this issue) and Potosky, Bobko and Roth (this issue) we emphasize that our proposal on Pareto‐optimal predictor composite formation is a complementary and not a competitive alternative for reducing the tension between selection quality and adverse impact. Our work addresses the decisions to be made once one has decided to use a predictor composite. We also further clarify the basic features of Pareto‐optimal tradeoffs and Pareto‐optimal composites within the context of personnel selection. In particular, we indicate that Pareto‐optimal tradeoffs between validity and adverse impact emerge because these goals are different and not because of any dualism between them.     

Stimulus–response bindings contribute to item switch costs in working memory

In counter updating tasks, responses are typically faster when items repeat than when they change (item switch costs). The present study explored the contribution of stimulus–response bindings to these item switch costs. In two experiments, we orthogonally manipulated the repetition/switch of to-be-counted items and the repetition/switch of required manual responses. Item switch costs were considerably lower when item switches were accompanied by response switches than when accompanied by response repetitions. Experiment 2 showed that, although there was also a smaller contribution from stimulus–stimulus bindings (i.e., shape-location), the major part was due to stimulus-response bindings. These results show that in the widely used standard version of the counter updating task, a considerable portion of item switch costs is caused by the unbinding of stimulus–response bindings rather than by processes of switching items in working memory.     

Cutoff Scores that Optimize the Utility of a Fixed Quota of Successful Employees Selection Decision

The new utility model, proposed previously by the author, is used to establish test cutoff scores that optimize the utility of a ‘fixed quota of successful employees selection decision’. Within the model, the problem can be formulated as a constrained non-linear program, and, to obtain the solution, a sequential quadratic programming method is implemented. Next, the approach is illustrated by means of an example application which relates to the selection of a fixed quota of five successful employees for an entrance management position. Apart from detailing certain computational aspects of the procedure, the example allows also to clarify the issue of practical relevance. Finally, the limitations, as well as a generalization of the procedure to the simultaneous estimation of both optimal test and criterion cutoffs, are discussed.
