Social Facilitation and Inhibition During Maximum Versus Typical Performance Situations

The distinction between maximum performance (“what people can do”) and typical performance (“what people will do”) has received considerable theoretical yet relatively little empirical attention. Findings from social facilitation and inhibition suggest that the relationship between performers' typical and maximum performance may not always be as straightforward as had originally been assumed. Ninety-four psychology students underwent a manipulation of their self-efficacy before doing an explaining task both under typical and maximum performance conditions. Results revealed a social inhibition effect in the maximum performance condition for participants of the low self-efficacy conditions. Implications and directions for future research are discussed.     

To transfer or not to transfer? Investigating the combined effects of trainee characteristics, team leader support, and team climate

Eighty pilots participated in a study of variables influencing the transfer process. Posttraining performance was assessed in a flight simulation under 1 of 2 conditions. Those in the maximum performance condition were made aware of the skill to be assessed and the fact that their teammates were confederates, whereas those in the typical performance condition were not. The results indicated that (a) simulator ratings correlated with a measure of transfer to the cockpit for those in the typical condition only; (b) team leader support, manipulated in a pretask brief, moderated the disparity between maximum and typical performance; (c) team climate mediated the impact of support on performance in the typical condition; (d) those with a stronger predisposition toward the trained skill viewed their climate as more supportive; and (e) perceptions of team climate were better predictors of performance for those with a more external locus of control.     

A Multiple-Task Measurement Framework for Assessing Maximum-Typical Performance

This study presents a novel measurement framework for assessing and predicting maximum and typical performance. The proposed measurement approach addresses the need for organizations to assess maximum and typical performance changes over time in complex job settings requiring coordination of multiple tasks with changing priorities. We present results of an experiment in which participants engaged in a complex task with multiple task elements and instructions to either maximize a different task element in each of four performance blocks (variable-priority condition) or treat all task elements with equal priority (stable-priority condition). We estimated growth curves corresponding to each task element and calculated the area under each growth curve as a summary performance index. Growth curves corresponding to the maximized, high-priority task element in the variable-priority condition reflected maximum performance, whereas those corresponding to the deemphasized, lower priority elements reflected typical performance. We compared the shape of the maximum and typical growth curves in the variable-priority condition to their corresponding performance trajectories in the stable-priority condition. In addition, we tested the moderating influence of individual differences in action-state orientation on the obtained maximum and typical performance estimates. Results indicated support for the proposed measurement framework in terms of its usefulness for inducing sustained levels of maximum performance and for identifying and correcting sources of the maximum-typical performance discrepancy.     

Transformational leadership: relations to the five-factor model and team performance in typical and maximum contexts

This study examined the 5-factor model of personality, transformational leadership, and team performance under conditions similar to typical and maximum performance contexts. Data were collected from 39 combat teams from an Asian military sample (N = 276). Results found that neuroticism and agreeableness were negatively related to transformational leadership ratings. Team performance ratings correlated at only.18 across the typical and maximum contexts. Furthermore, transformational leadership related more strongly to team performance in the maximum rather than the typical context. Finally, transformational leadership fully mediated the relationship between leader personality and team performance in the maximum context but only partially mediated the relationship between leader personality and team performance in the typical context. The Discussion section focuses on how these findings, although interesting, need to be replicated with different designs, contexts, and measures.     

Latent constructs of proximal and distal motivation predicting performance under maximum test conditions

The concept of a maximum-typical performance dimension has received theoretical and empirical support in research on the construct of job performance. The critical distinction between maximum and typical performance resides in the postulate that under maximum test conditions motivational factors will be constant and maximal. The present study challenges the notion of the maximum performance paradigm by testing the effects of proximal (self-efficacy) and distal (need for achievement) motivation on performance under maximum test conditions. The authors used a walk-through performance test to evaluate the performance of 90 employees. The structural model demonstrates significant pathways between latent measures of motivation and performance ratings. The findings confirm the explanatory power of the motivation construct under maximum test conditions.     

The Moderating Influence of Personality and Culture on Social Loafing in Typical versus Maximum Performance Situations

The current paper combines research from personality, cultural, social, and work‐ and organizational psychology. More precisely, it addresses the motivating effects of situations that either foster or inhibit social loafing under typical vs maximum performance conditions. It further tests how these effects are moderated by the three individual difference variables of conscientiousness, agreeableness, and openness to experience, and the two cultural dimension variables of collectivism and power distance. Results reveal positive main effects for inherently motivating situations, maximum performance conditions, conscientiousness, agreeableness and collectivism, as well as a significant interaction between the degree to which the situation invites social loafing and the typical vs maximum performance condition. These findings thus confirm a possible overlap between the theories of social loafing and of typical vs maximum performance. Finally, power distance showed a number of surprising interactions that may, in part, account for cultural differences found in the social loafing literature. Implications for theory building, empirical research and practice are discussed.     

EXPLORING RELATIONS BETWEEN TYPICAL AND MAXIMUM PERFORMANCE RATINGS AND THE FIVE FACTOR MODEL OF PERSONALITY

The study tests the distinction between typical and maximum criteria with ratings of transformational leadership performance, and examines whether the criterion-related validities of the five factor model differ for the two types of criteria. Using an East Asian military sample ( n = 1,259) where multiple ratings of typical and maximum performance were obtained from different sources, we used structural equation modeling to test the typical/maximum performance distinction. Results found that typical and maximum performance are different latent constructs and that this distinction is present even after considering rating method factors (i.e., rater source, time). The importance of this distinction is shown by the fact that validities for the personality constructs were not equally predictive of both criteria: Openness was most predictive of maximum performance, Neuroticism was most predictive of typical performance, and Extroversion was predictive of both. By distinguishing typical from maximum performance constructs, relationships between personality and transformational leadership were found to be stronger than previous research suggested.     

Personality and Cognitive Ability as Predictors of Typical and Maximum Managerial Performance

Despite long-established distinctions between typical and maximum performance variables on both the predictor and criterion side, little previous research has directly addressed the extent to which these distinctions translate into differential predictor-criterion relationships. Using a sample of candidates for managerial positions, we examined relations of predictors conceptually linked to typical (i.e., broad, narrow, and compound personality traits) and maximum (i.e., broad and narrow cognitive abilities) performance with corresponding criterion measures (N = 84–873). Supervisory ratings of managerial performance served as the typical performance criterion, whereas maximum performance was assessed via an assessment center. Confirmatory factor analyses supported the distinction between typical and maximum performance. Results also confirmed our hypothesis that cognitive abilities are more strongly correlated with maximum performance than with typical performance and largely supported the expectation of the opposite pattern with personality traits as predictors.     

Meta-analytic interval estimation for bivariate correlations

The currently available meta-analytic methods for correlations have restrictive assumptions. The fixed-effects methods assume equal population correlations and exhibit poor performance under correlation heterogeneity. The random-effects methods do not assume correlation homogeneity but are based on an equally unrealistic assumption that the selected studies are a random sample from a well-defined superpopulation of study populations. The random-effects methods can accommodate correlation heterogeneity, but these methods do not perform properly in typical applications where the studies are nonrandomly selected. A new fixed-effects meta-analytic confidence interval for bivariate correlations is proposed that is easy to compute and performs well under correlation heterogeneity and nonrandomly selected studies.

Differential relationship of recent self-reported stress and acute anxiety with divided attention performance

There have been relatively few studies on the relationship between recent perceived environmental stress and cognitive performance, and the existing studies do not control for state anxiety during the cognitive testing. The current study addressed this need by examining recent self-reported environmental stress and divided attention performance, while controlling for state anxiety. Fifty-four university undergraduates who self-reported a wide range of perceived recent stress (10-item perceived stress scale) completed both single and dual (simultaneous auditory and visual stimuli) continuous performance tests. Partial correlation analysis showed a statistically significant positive correlation between perceived stress and the auditory omission errors from the dual condition, after controlling for state anxiety and auditory omission errors from the single condition (r = 0.41). This suggests that increased environmental stress relates to decreased divided attention performance in auditory vigilance. In contrast, an increase in state anxiety (controlling for perceived stress) was related to a decrease in auditory omission errors from the dual condition (r = - 0.37), which suggests that state anxiety may improve divided attention performance. Results suggest that further examination of the neurobiological consequences of environmental stress on divided attention and other executive functioning tasks is needed.     

Reciprocation of generosity and knowledge of game termination in the decomposed Prisoner's Dilemma Game

Sahlins proposed a model of reciprocity for social interaction citing three forms drawn from observations of kinship systems. The model describes an altruistic form of reciprocity, a balanced or economic form and a negative form in which individuals try to outdo each other. This model was applied to a two-person variation of the Prisoner's Dilemma Game where Ss were presented with a confederate who responded over trials entirely generously, contingently generously or non-generously. Half of the Ss were informed that there would be ten trials while the other half were uninformed. Basically, Ss tended to match the generosity level of the confederate and were less generous when trial number was known. Evidence for Sahlins' model is provided by Ss reports of reasons for their choices in the game. Those in the generous condition gave reasons for reciprocating based on a general feeling of obligation, trust and desire to cooperate. Those in the contingently generous condition gave reasons for reciprocating based on economic exchange and a desire to maintain a balance of resources. Ss in the non-generous condition gave reasons based on a desire to take what profits one could before the other got them. In addition, Ss indicated a significant tendency to exploit the other on the final trial under the informed condition for the contingently generous but not for the generous condition.     

Person—Situation Predictors of Maximum and Typical Performance

We examined the main and interactive effects of general mental ability (GMA) and perceived organizational support (POS) on typical performance and maximum performance. Data from two field samples (96 programmers and 181 cash vault employees) empirically supported distinguishing between typical performance and maximum performance. GMA was related to maximum performance but not to typical performance, and POS was related to two out of three measures of typical performance. Interactive effects of GMA and POS were detected in both samples for maximum performance outcomes but not found for typical performance outcomes.

Accounting for Missing Correlation Coefficients in Fixed-Effects MASEM

Meta-analytic structural equation modeling (MASEM) is increasingly applied to advance theories by synthesizing existing findings. MASEM essentially consists of two stages. In Stage 1, a pooled correlation matrix is estimated based on the reported correlation coefficients in the individual studies. In Stage 2, a structural model (such as a path model) is fitted to explain the pooled correlations. Frequently, the individual studies do not provide all the correlation coefficients between the research variables. In this study, we modify the currently optimal MASEM-method to deal with missing correlation coefficients, and compare its performance with existing methods. This study is the first to evaluate the performance of fixed-effects MASEM methods under different levels of missing correlation coefficients. We found that the often used univariate methods performed very poorly, while the multivariate methods performed well overall.     

Global dot integration in typically developing children and in Williams Syndrome

Williams Syndrome (WS) is a neurodevelopmental disorder that results in deficits in visuospatial perception and cognition. The dorsal stream vulnerability hypothesis in WS predicts that visual motion processes are more susceptible to damage than visual form processes. We asked WS participants and typically developing children to detect the global structure Glass patterns, under “static” and “dynamic” conditions in order to evaluate this hypothesis. Sequentially presented Glass patterns are coined as dynamic because they induce illusory motion, which is modeled after the interaction between orientation (form) and direction (motion) mechanisms. If the dorsal stream vulnerability holds in WS participants, then they should process real and illusory motion atypically. However, results are consistent with the idea that form and motion integration mechanisms are functionally delayed or attenuated in WS. Form coherence thresholds for both static and dynamic Glass patterns in WS were similar to those of 4–5 year old children, younger than what is predicted by mental age. Dynamic presentation of Glass patterns improved thresholds to the same degree as typical participants. Motion coherence thresholds in WS were similar to those of mental age matches. These data pose constraints on the dorsal vulnerability hypothesis, and refine our understanding of the relationship between form and motion processing in development.     

Independent mechanisms for dividing attention between the motion and the color of dynamic random dot patterns

The present study investigated the division of attention between different visual attributes, which is a cognitive function implicated in the selection of information in a given condition. To examine the underlying mechanisms, we focused on motion and color as visual attributes. In Experiment 1, performance on single- and dual-judgment for motion and color of dynamic random dot patterns presented in a restricted visual field was examined under different priority conditions. Accuracy was the same for single- and dual-task conditions, and the attention operating characteristic (AOC) analysis indicated that motion and color perception do not share the same processing capacity. In addition, correlation analysis indicated that, on a trial-by-trial basis, performance on motion and color was considerably independent. In Experiment 2, a brief lateral cue preceded the dynamic random dot patterns. The cue affected only motion-judgment, even under dual-task conditions of motion and color. These results suggest that dividing attention between motion and color involves independent mechanisms.
