Climate and Creativity: Cold and Heat Trigger Invention and Innovation in Richer Populations

Nobel laureates, technological pioneers, and innovative entrepreneurs are unequally distributed across the globe. Their density increases in regions toward the North Pole, toward the South Pole, and very close to the Equator. This geographic anomaly led us to explore whether stressful demands of climatic cold and climatic heat (imposed necessities) interact with economic wealth resources (available opportunities) in modulating creative culture—defined here as including both inventive idea generation and innovative idea implementation. Controlling for societal intellectualization, industrialization, and urbanization, results indicated that higher thermal demands, primarily cold stress and secondarily heat stress, hinder creativity in poorer populations but promote creativity in richer populations. Complementing their direct wealth-dependent effects, colder and hotter temperatures also exert indirect wealth-dependent effects on creative culture through lower prevalence of human-to-human transmitted parasitic diseases. Across 155 countries, the resulting ecotheory of creativity accounts for 79% of the variation in creative culture. The findings open up valuable perspectives on the creativity-related consequences of thermal climate—and climate change—in poor and rich populations.     

An event-related visual occlusion method for examining anticipatory skill in natural interceptive tasks

This article describes a new automated method for the controlled occlusion of vision during natural tasks. The method permits the time course of the presence or absence of visual information to be linked to identifiable events within the task of interest. An example application is presented in which the method is used to examine the ability of cricket batsmen to pick up useful information from the prerelease movement patterns of the opposing bowler. Two key events, separated by a consistent within-action time lag, were identified in the cricket bowling action sequence—namely, the penultimate foot strike prior to ball release (Event 1), and the subsequent moment of ball release (Event 2). Force-plate registration of Event 1 was then used as a trigger to facilitate automated occlusion of vision using liquid crystal occlusion goggles at time points relative to Event 2. Validation demonstrated that, compared with existing approaches that are based on manual triggering, this method of occlusion permitted considerable gains in temporal precision and a reduction in the number of unusable trials. A more efficient and accurate protocol to examine anticipation is produced, while preserving the important natural coupling between perception and action.     

Creating Through Deviancy or Adjustment? The Link between Personality Profile Normativeness and Creativity

Does deviancy or adjustment predict creativity? To address this question, we tested the association between personality profile normativeness (similarity between one's personality profile and the average profile—a proxy for the deviancy–adjustment continuum) and creativity across four different samples (total N = 348 768). We used a wide range of creativity measures, including self‐reported, informant‐reported, behavioural, and occupational creativity, as well as several essential statistical controls (i.e., demographics, socio‐economic background, intelligence, and life satisfaction). Furthermore, we employed both cross‐sectional and longitudinal designs, including samples of college students and representative adult populations. We found that people who had more normative personality profiles were more creative. However, this association only held within modality (i.e. when both personality and creativity were either self‐reported or informant‐reported). We did not find robust associations between personality profile normativeness and laboratory‐based behavioural measures of creativity, occupational creativity, or creative achievements. We discuss alternative explanations for the observed adjustment–creativity link, specifically, implicit theories of creativity and person perception biases (halo effects). Notably, the findings did not support the idea that deviancy breeds creativity, suggesting that the famed ‘mad genius’ hypothesis might not hold among the general population. © 2019 European Association of Personality Psychology     

The Trouble with Truth-Makers

This paper argues that theories of truth which seek to specify the ontological ground of true statements by appealing to an ontology of truth-makers face a severe and possibly insurmountable obstacle in the form of logically complex statements. I argue that there is no apparent way to develop an account of logically complex truth within the confines of a modest and plausible ontology of truth-makers and to this end criticize independent attempts by Armstrong and Pendlebury to develop such an account.     

Refractory effects in picture naming as assessed in a semantic blocking paradigm.

In the cyclic semantic blocking paradigm participants repeatedly name sets of objects with semantically related names (homogeneous sets) or unrelated names (heterogeneous sets). The naming latencies are typically longer in related than in unrelated sets. In Experiment 1 we replicated this semantic blocking effect and demonstrated that the effect only arose after all objects of a set had been shown and named once. In Experiment 2, the objects of a set were presented simultaneously (instead of on successive trials). Evidence for semantic blocking was found in the naming latencies and in the gaze durations for the objects, which were longer in homogeneous than in heterogeneous sets. For the gaze-to-speech lag between the offset of gaze on an object and the onset of the articulation of its name, a repetition priming effect was obtained but no blocking effect. Experiment 3 showed that the blocking effect for speech onset latencies generalized to new, previously unnamed lexical items. We propose that the blocking effect is due to refractory behaviour in the semantic system.
