Contextual Performance and the Job Satisfaction–Dissatisfaction Distinction: Examining Artifacts and Utility

The relationship between contextual performance and job satisfaction is reexamined by considering the distinction between scores on measures of satisfaction and measures of dissatisfaction. Data from four samples and two measures of job satisfaction suggest that scores on measures of both satisfaction and dissatisfaction provide significant incremental validity in predicting contextual performance, that the satisfaction–dissatisfaction distinction is valid at the facet level, and that the satisfaction–dissatisfaction distinction cannot be accounted for by the artifactual explanations previously proposed in the literature.     

The Blacky Pictures as Personality Measures for Undergraduate Areas of Specialization

Thematic Apperception Test (Murray, 1943) responses of 69 Asian American (hereafter, Asian) and 83 White students were coded for defenses according to the Defense Mechanism Manual (Cramer, 1991b) and studied for differential validity in predicting paper-and-pencil measures of relevant constructs. Three tests for differential validity were used: (a) differences between validity coefficients, (b) interactions between predictor and ethnicity in criterion prediction, and (c) differences between groups in mean prediction errors using a common regression equation. Modest differential validity was found. It was surprising that the DMM scales were slightly stronger predictors of their criteria among Asians than among Whites and when a common predictor was used, desirable criteria were overpredicted for Asians, whereas undesirable ones were overpredicted for Whites. The results were not affected by acculturation level or English vocabulary among the Asians.     

Neuronal correlates of decisions to speak and act: Spontaneous emergence and dynamic topographies in a computational model of frontal and temporal areas

The neural mechanisms underlying the spontaneous, stimulus-independent emergence of intentions and decisions to act are poorly understood. Using a neurobiologically realistic model of frontal and temporal areas of the brain, we simulated the learning of perception–action circuits for speech and hand-related actions and subsequently observed their spontaneous behaviour. Noise-driven accumulation of reverberant activity in these circuits leads to their spontaneous ignition and partial-to-full activation, which we interpret, respectively, as model correlates of action intention emergence and action decision-and-execution. Importantly, activity emerged first in higher-association prefrontal and temporal cortices, subsequently spreading to secondary and finally primary sensorimotor model-areas, hence reproducing the dynamics of cortical correlates of voluntary action revealed by readiness-potential and verb-generation experiments. This model for the first time explains the cortical origins and topography of endogenous action decisions, and the natural emergence of functional specialisation in the cortex, as mechanistic consequences of neurobiological principles, anatomical structure and sensorimotor experience.     

Shedding light on insight: Priming bright ideas

Previous research has characterized insight as the product of internal processes, and has thus investigated the cognitive and motivational processes that immediately precede it. In this research, however, we investigate whether insight can be catalyzed by a cultural artifact, an external object imbued with learned meaning. Specifically, we exposed participants to an illuminating lightbulb - an iconic image of insight - prior to or during insight problem-solving. Across four studies, exposing participants to an illuminating lightbulb primed concepts associated with achieving an insight, and enhanced insight problem-solving in three different domains (spatial, verbal, and mathematical), but did not enhance general (non-insight) problem-solving.

On Gratitude to Nature

In this article, I argue that it cannot be fitting to be grateful to nature. I start by arguing that gratitude to someone/something can be fitting even if they do not intentionally benefit one. I then argue that a recent view on which it can be fitting to be grateful to nature faces counterexamples. Finally, I argue that it cannot be fitting to be grateful to nature, because it is fitting to be grateful to someone/something only if they manifest the right kind of goodwill or care toward one. In particular, I argue that it is fitting to be grateful to someone/something only if they manifest a level of final care toward one beyond what can be legitimately expected or demanded of them. However, because nature does not manifest any level of goodwill or care, it cannot be fitting to be grateful to nature. I end by noting that it can still be fitting to be grateful that certain things are true about nature (e.g. that it provides many benefits to humans).     

Affective divergence: automatic responses to others' emotions depend on group membership

Extant research suggests that targets' emotion expressions automatically evoke similar affect in perceivers. The authors hypothesized that the automatic impact of emotion expressions depends on group membership. In Experiments 1 and 2, an affective priming paradigm was used to measure immediate and preconscious affective responses to same-race or other-race emotion expressions. In Experiment 3, spontaneous vocal affect was measured as participants described the emotions of an ingroup or outgroup sports team fan. In these experiments, immediate and spontaneous affective responses depended on whether the emotional target was ingroup or outgroup. Positive responses to fear expressions and negative responses to joy expressions were observed in outgroup perceivers, relative to ingroup perceivers. In Experiments 4 and 5, discrete emotional responses were examined. In a lexical decision task (Experiment 4), facial expressions of joy elicited fear in outgroup perceivers, relative to ingroup perceivers. In contrast, facial expressions of fear elicited less fear in outgroup than in ingroup perceivers. In Experiment 5, felt dominance mediated emotional responses to ingroup and outgroup vocal emotion. These data support a signal-value model in which emotion expressions signal environmental conditions.
