A Theory of Individual Differences in Task and Contextual Performance

This article describes a theory of job performance that assumes that job performance is behavioral, episodic, evaluative, and multidimensional. It defines job performance as the aggregated value to the organization of the discrete behavioral episodes that an individual performs over a standard interval of time. It uses the distinction between task and contextual performance to begin to identify and define underlying dimen- sions of the behavioral episodes that make up the performance domain. The theory predicts that individual differences in personality and cognitive ability variables, in combination with learning experiences, lead to variability in knowledge, skills, and work habits that mediate effects of personality and cognitive ability on job perform- ance. An especially important aspect of this theory is that it predicts that the kinds of knowledge, skills, work habits, and traits that are associated with task performance are different from the kinds that are associated with contextual performance.     

An alternative perspective on von Winterfeldt et al.'s (1997) test of consequence monotonicity

D. von Winterfeldt, N.-K. Chung, R. D. Luce, and Y. Cho (1997) provided several tests for consequence monotonicity of choice or judgment, using certainty equivalents of gambles. The authors reaxiomatized consequence monotonicity in a probabilistic framework and reanalyzed von Winterfeldt et al.'s main experiment via a bootstrap method. Their application offers new insights into consequence monotonicity as well as into von Winterfeldt et al.'s 3 experimental paradigms: judged certainty equivalents (JCE), QUICKINDIFF, and parameter estimation by sequential testing (PEST). For QUICKINDIFF, the authors found no indication of violations of "random consequence monotonicity." This sharply contrasts the findings of von Winterfeldt et al., who concluded that axiom violations were the most pronounced under that procedure. The authors found potential evidence for violations in JCE and certainty equivalents derived from PEST.     

Hemisphericsymmetries in the identification of band-pass filtered letters Reply to Christman et al. (1997)

Christman, Kitterle, and Niebauer (1997) have examined the hypothesis that the two cerebral hemispheres are specialized for processing different ranges of spatial frequency. Their two experiments partially replicated an experiment of Peterzell, Harvey, and Hardyck (1989), who used Sergent's (1982) letter identification paradigm with spatial-frequency band-pass filtered letters as stimuli. We acknowledge the unusual strengths of Christman et al.'s experiments, but argue that the results support the original conclusion of Peterzell et al.: The results are not attributable to hemispheric asymmetries in spatial frequency processing.     

A critique of Lilienfeld et al.'s (2000) "The scientific status of projective techniques"

Lilienfeld, Wood, and Garb (2000) published a largely negative critique of the validity and reliability of projective methods, concentrating on the Comprehensive System for the Rorschach (Exner, 1993), 3 systems for coding the Thematic Apperception Test (TAT; Murray, 1943) cards, and human figure drawings. This article is an effort to document and correct what I perceive as errors of omission and commission in the Lilienfeld et al. article. When projective measures are viewed in the light of these corrections, the evidence for the validity and clinical usefulness of the Rorschach and TAT methods is more robust than Lilienfeld et al. represented.     

Lessons From Markey et al. (2015) and Bushman et al. (2015): Sensationalism and Integrity in Media Research

This article presents a response to the comment by B. J. Bushman, D. Romer, and P. E. Jamieson (2015). This reply addresses 2 issues raised by the commenters. First, they claim they and others have not made sensationalistic statements linking violent media to horrific acts of real‐world violence. In response, we supply numerous examples of sensationalistic statements made by them and others. Second, they claim they did not expect violence in films to be related to violent behavior among adults, but only among youths. However, by examining homicide arrests and homicide gun mortality rates among youths, we found that as films have become increasingly violent over time, both homicide arrests and gun‐related homicides have tended to decrease among this age group.     

Oddities in Kirkpatrick, et al.'s study of children of lesbian mothers

Kirkpatrick, et al.'s 1976 study of what happened to 20 lesbians' children has received considerable attention, apparently later being matched with 20 heterosexuals' children. In 2004, Kirkpatrick generally acknowledged Schumm's caution that her findings are less impressive than are needed, yet, Kirkpatrick stated her "early findings have been reinforced" and that "no evidence of differences in the children grouped by the mother's sexual orientation" have been documented by subsequent research. Close examination of the data of these studies indicates that children from 13 lesbian mothers were compared with children from 13 divorced heterosexuals. Further, there are contradictions between the published reports regarding the nature of samples and various findings. Analysis of Kirkpatrick, et al.'s study suggests that children do less well when raised by homosexual parents.     

On the importance of models in interpreting remember-know experiments: comments on Gardiner et al.'s (2002) meta-analysis

From a meta-analysis of recognition experiments using the remember-know-guess paradigm, Gardiner, Ramponi, and Richardson-Klavehn (2002) reported two findings that they viewed as evidence against the one-dimensional model for that paradigm: (1) Memory strength increased when know responses were added to remember responses, decreasing when guess responses were also included. (2) The accuracy of guess responses was correlated with the location of the old-new criterion in the one-dimensional model for the paradigm, implying that guesses were influenced by decision processes. We question both findings. The first result is contradicted by a signal-detection (SDT) analysis, which shows that both know and guess responses reduced estimated memory strength. The discrepancy results from the properties of A', the measure of accuracy used by Gardiner et al., which we argue is flawed. The second result follows directly from the one-dimensional model, in which accuracy and response criteria are fixed. The authors' reasons for rejecting the one-dimensional model are thus not persuasive, but it can nonetheless be rejected because ROC curves implied by the data are inconsistent with ROCs derived from ratings experiments. A two-dimensional SDT model (Rotello, Macmillan, & Reeder, 2004) accounts for both sets of data. The analysis illustrates the importance of models in interpreting remember--know data.

Individual Differences in Children (Book)

This study involved a comparison of the factor structure of the MCMI in: a general psychiatric sample, a substance misuse sample, and a drug misuse sample. Examination of the factor matrices for the three clinical samples provided evidence for a sturdy factor measuring a negativistic-avoidant personality style with associated anxiety, depression, and somatization. Evidence was also available in all three samples for factors measuring: a) a paranoid cognitive and interpersonal pattern, and b) an asocial-avoidant personal orientation.     

Relationships between Facets of Job Satisfaction and Task and Contextual Performance

This study examined the relationship between job satisfaction and task and contextual performance. Specifically, it assessed this relationship for overall as well as facets of job satisfaction. Four hundred and forty‐four employees in a manufacturing plant completed measures of job satisfaction and their supervisors completed measures of task and contextual job performance. Results indicate that the relationships between overall job satisfaction and task and contextual performance were the same. However, when the facets of job satisfaction were considered, different relationships emerged. There was a stronger relationship between satisfaction with supervision and contextual performance compared to task performance. In contrast, there was a stronger relationship between satisfaction with work and task performance compared to contextual performance. Results indicated the importance of considering different facets with the job satisfaction and job performance relationship, as well as the importance of matching predictors and criteria in terms of their levels of specificity. Cette étude examine la relation entre la satisfaction au travail, la tâche et la performance en contexte. Plus spécifiquement, cette relation a étéévaluée en envisageant la relation au travail de façon globale ou selon différentes facettes. La satisfaction au travail a été mesurée auprès de 444 salariés d’une usine de fabrication, la tâche et la performance en contexte ont étéévaluées par leurs supérieurs. Les résultats indiquent que les relations entre la satisfaction au travail envisagée de façon globale, la tâche et la performance en contexte sont les mêmes. Cependant, quand on distingue les facettes de la satisfaction au travail, des relations différentes émergent. Il y a une relation plus importante entre la satisfaction envers la supervision et la performance en contexte qu’entre la satisfaction envers la supervision et la performance. En revanche, il y a une relation plus forte entre la satisfaction du travail et la performance qu’entre la satisfaction du travail et la performance en contexte. Les résultats indiquent l’importance de trouver des indicateurs et des critères qui rendent compte de ces spécificités.     

An evaluation of a computational model of lexical access: comment on Dell et al. (1997)

The computational model of lexical access proposed by G. S. Dell, M. F. Schwartz, N. Martin, E. M. Saffran, and D. A. Gagnon (1997) is evaluated. They argued that fits of their model to naming data obtained from normal and brain-damaged patients support assumptions regarding interactivity in the lexicon, global damage in aphasia, and continuity between normal and aphasic naming behavior. Additional analysis reveals that the model fits the empirical data poorly and that the claims Dell et al. made on the basis of the model's performance would not follow even if the model were accurate. Although use of a novel automatic regression procedure improved the model's fit, it cannot account for 5 of Dell et al.'s 21 patients (24%), and its limitations were found to be inherent in its design. It is argued that claims such as those made by Dell et al. can only be addressed by considering evidence from multiple related tasks and by comparing multiple computational models.     

The study of inhibitory processes in aging with the Faust et al. paradigm (1997): methodological issues

Information provided by a word activates various potential meanings. Comprehension involves the suppression of inappropriate meanings of ambiguous words in order to finetune the intended meaning of sentences. If older adults become less efficient at inhibiting contextually irrelevant information, then multiple meanings of ambiguous words would be activated regardless of contextual bias. An alternative to multiple access was that older adults activate only the most dominant meaning of ambiguous words. According to this reservation, support for an inhibition deficit would require evidence that older adults activated the multiple meanings of ambiguous words. The effects of aging on both activation and inhibition of different meanings of ambiguous words were studied using Faust et al. (1997) paradigms. Results showed that both activation and inhibition response latency differed for the dominant and subordinate target and that the dominant meaning for one subject was not the same for another one. The implication of these results is that studies of inhibition should take dominance meaning of ambiguous word for each subject into account.     

The validity and appropriateness of methods, analyses, and conclusions in Rind et al. (1998): A rebuttal of victimological critique from Ondersma et al. (2001) and Dallam et al. (2001).

The authors respond to 2 victimological critiques of their 1998 meta-analysis on child sexual abuse (CSA). S. J. Dallam et al. (2001) claimed that B. Rind, P. Tromovitch, and R. Bauserman (1998) committed numerous methodological and statistical errors, and often miscoded and misinterpreted data. The authors show all these claims to be invalid. To the contrary, they demonstrate frequent bias in Dallam et al.'s criticisms. S. J. Ondersma et al. (2001) claimed that Rind et al.'s study is part of a backlash against psychotherapists, that its suggestions regarding CSA definitions were extrascientific, and that the moral standard is needed to understand CSA scientifically. The authors show their suggestions to have been scientific and argue that it is Ondersma et al.'s issue-framing and moral standard that are extrascientific. This reply supports the original methods, analyses, recommendations, and conclusions of Rind et al.     

Response to Pashler et al. (2016)

Pashler, Rohrer, Abramson, Wolfson, and Harris (2016/this issue) in their critique of Chatterjee, Rose, and Sinha (2013 Chatterjee, P., Rose, R., &; Sinha, J. (2013). Why money meanings matter in decisions to donate time and money. Marketing Letters, 24, 109–118. doi:10.1007/s11002-012-9215-0[Crossref], [Web of Science ®] , [Google Scholar]) data argue that (a) large effect sizes in Study 1 and Study 2 undermine the credibility of the data; (b) in a lexical task that is part of Study 3, a concentration of participants in (5,0) and (0,5) benefit/cost word data points and the similarity of 9 neutral word responses at these points are extremely unlikely; and (c) there are apparent errors in the execution of Study 3. In this response, I examine these issues in detail. A recent review of money prime literature (Vohs, 2015 Vohs, K. (2015). Money priming can change people’s thoughts, feelings, motivations, and behaviors: An update on 10 years of experiments. Journal of Experimental Psychology: General, 144(4), e86–e93. doi:10.1037/xge0000091[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) notes many effect sizes that are as big as or bigger than ours. Although 8 coding errors were discovered in Study 3 data and this particular study has been retracted from that article, as I show in this article, the arguments being put forth by the critics are untenable. For instance, my analysis shows that results hold even without the concentration of (5,0) and (0,5) participants, and I offer statistical simulations to counter critics’ arguments. Regarding the apparent errors in Study 3, I find that removing the target word stems SUPP and CE do not influence findings in any way. I also report findings from MacDonnell and White (2015 MacDonnell, R., &; White, K. (2015). How construals of money versus time impact consumer charitable giving. Journal of Consumer Research, 42, 551–563. doi:10.1093/jcr/ucv042[Crossref] , [Google Scholar]), who replicate the basic finding of Chatterjee et al. in a different context.     

Supernumerary phantoms: a comment on Grossi, et al.'s (2002) spare thoughts on spare limbs

A recently published case report of a supernumerary phantom limb in a man with left-sided hemiplegia did not take note that this phenomenon has been extensively documented in the neurological literature for well over 100 years. The present comment provides a brief introduction to the clinical and experimental approaches to supernumerary phantom limbs. It also emphasizes the theoretical importance of this condition for understanding the neurological mechanisms subserving the experience of having a body.     

An Evaluation of James et al.'s (1992) VG Estimation Procedure when Artifacts and True Validity are Correlated*

James, Demaree, Muliak, and Ladd (1992) outlined a procedure for estimating the mean (M) and variance (V) of true validities (ρ's). This procedure was designed to take into account the potential nonzero intercorrelations among the three artifacts (predictor reliability, criterion reliability, and range restriction) and ρ. The accuracy of this new validity generalization procedure was compared with the accuracy of the Model 2‐based (in which correlations are individually corrected for artifacts) procedure because this latter procedure does not require the assumption of uncorrelated artifacts. The current study included two different ρ distributions, three sample sizes, and six different levels of intercorrelations among the three artifacts and ρ. Both procedures yielded relatively accurate estimates of M and V even when the intercorrelations among the three artifacts and ρ were nonzero. The Model 2‐based estimates were slightly more accurate than the James et al. estimates, and the accuracy of the Model 2‐based estimates was much more stable across sample sizes and different levels of intercorrelatedness. Sample‐based artifact data were used in this investigation.
