Mild Affective Shifts and Creativity: Effects on Idea Generation,Evaluation, and Implementation Planning

This study investigated the impact of mild shifts in affective tone (i.e., pleasant vs. unpleasant) and arousal (i.e., high vs. low) on three creative processes. Undergraduates read short stories designed to induce affective shifts and then were asked to generate solutions to a complex business problem. Shifts in affective tone and arousal interacted to influence idea generation and implementation planning, but not idea evaluation. The strongest creative performance was exhibited by participants who experienced a stable and pleasantly toned, low-arousal (i.e., relaxed) state and by those who shifted to an unpleasantly toned, high-arousal (i.e., angry) state. In contrast, those who shifted to an unpleasantly toned, low-arousal (i.e., sad) state or a pleasantly toned, high-arousal (i.e., happy) state tended to exhibit poorer creative performance. These results demonstrate the need to revisit the popular conception that organizations should promote intense levels of pleasant affect to enhance employee creativity.     

Individuation and explanation: a problem for dispositionalism

Children's expectations and episodic reports over 12 weeks: Influences on memory for a specially designed pediatric examination

This investigation extended work on the linkage between knowledge and remembering by exploring the relation between generic and episodic memory representations. Thirty 6-year-old children experienced a mock physical examination with some expected components omitted and other unexpected actions included. Immediately and again after 12 weeks, the children reported the event, answered questions about what usually happens in an examination, and rated their confidence in aspects of their reports. They remembered more typical than atypical present components, that is, those included in the examination, and, over time, falsely reported more typical than atypical actions. The children produced intrusions of expected-but-omitted medical features at the delay but with lower confidence ratings than they provided for correctly recalled items. Performance on a source monitoring task was associated with aspects of the children's confidence ratings for intrusions. The findings provide evidence that the relation between episodic and generic representations is dynamic and suggest that the capacity to differentiate between them contributes to the development of accurate eyewitness memory.     

Has Oppy Done Away with the Aristotelian Proof?

In this essay, we engage with Graham Oppy’s work on Thomas Aquinas’s First Way. We argue that Oppy’s objections shouldn’t be seen as successful. In order to establish this thesis, we first analyze Oppy’s exegesis of Aquinas’s First Way, as well as the counter-arguments he puts forth (including the charge that Aquinas’s argument is invalid or, if deemed valid, forces one to adopt determinism). Next, we address Oppy’s handling of the contemporary scholarship covering the First Way. Specifically, we lay out Edward Feser’s most recent formulation of the argument and analyze Oppy’s main objection to it.     

Logistic growth curve analysis in associative learning data

We propose an alternative statistical method, logistic growth curve analysis, for the analysis of associative learning data with two or more comparison groups. Logistic growth curve analysis is more sensitive and easier to interpret than previously published methods such as χ² or ANOVA, which require the data to be collapsed into individual total scores or proportion of responses over time. Additionally, this type of analysis better fits the typical graphical representation of associative learning data. An analysis is presented where associative learning data from honeybees are analyzed using the three techniques, and the accessibility and power of the logistic growth curve analysis is highlighted.

The Cognitive Demands of Gait Retraining in Runners: An EEG Study

Abstract

High impact forces during running have been associated with tibial stress injuries. Previous research has demonstrated increasing step rate will decrease impact forces during running. However, no research has determined the cognitive demand of gait retraining. The primary purpose was to determine the cognitive demand and effectiveness of field-based gait retraining. We hypothesized that in-field gait retraining would alter running mechanics without increasing cognitive workload as measured by EEG following learning. Runners with a history of tibial injury completed a gait retraining protocol which included a baseline run, retraining phase, practice phase, and re-assessment following retraining protocol. Results demonstrated an increase in the theta, beta, and gamma power within prefrontal cortex during new learning and corresponding return to baseline following skill acquisition and changes across alpha, beta, gamma, mu, and theta in the motor cortex (p < .05). In the midline superior parietal cortex, spectral power was greater for theta activity during new learning with a corresponding alpha suppression. Overall, the results demonstrated the use of EEG as an effective tool to measure cognitive demand for implicit motor learning and the effectiveness of in-field gait retraining.
