Sympathetic arousal, but not disturbed executive functioning, mediates the impairment of cognitive flexibility under stress

Cognition

Published in: Cognition, Volume 174, May 2018, 94-102 Abstract “Cognitive flexibility emerges from an interplay of multiple cognitive systems, of which lexical-semantic and executive are thought to be the most important. Yet this has not been addressed by previous studies demonstrating that such forms of flexible thought deteriorate under stress. Motivated by these shortcomings, the present study […]

A thought in the park: The influence of naturalness and low-level visual features on expressed thoughts

Cognition

Published in: Cognition, Volume 174, May 2018, 82-93 Abstract “Prior research has shown that the physical characteristics of one’s environment have wide ranging effects on affect and cognition. Other research has demonstrated that one’s thoughts have impacts on mood and behavior, and in this three-part research program we investigated how physical features of the environment can

Effects of metric hierarchy and rhyme predictability on word duration in The Cat in the Hat

Cognition

Published in: Cognition, Volume 174, May 2018, 71-81 Abstract “Word durations convey many types of linguistic information, including intrinsic lexical features like length and frequency and contextual features like syntactic and semantic structure. The current study was designed to investigate whether hierarchical metric structure and rhyme predictability account for durational variation over and above other features in productions

Dynamic competition account of men’s perceptions of women’s sexual interest

Cognition

Published in: Cognition, Volume 174, May 2018, 43-54 Abstract “This work applies a dynamic competition framework of decision making to the domain of sexual perception, which is linked theoretically and empirically to college men’s risk for exhibiting sexual coercion and aggression toward female acquaintances. Within a mouse-tracking paradigm, 152 undergraduate men viewed full-body photographs of women

Investing in commitment: Persistence in a joint action is enhanced by the perception of a partner’s effort

Cognition

Published in: Cognition, Volume 174, May 2018, 37-42 Abstract “Can the perception that one’s partner is investing effort generate a sense of commitment to a joint action? To test this, we developed a 2-player version of the classic snake game which became increasingly boring over the course of each round. This enabled us to operationalize commitment

Adding statistical regularity results in a global slowdown in visual search

Cognition

Published in: Cognition, Volume 174, May 2018, 19-27 Abstract “Current statistical learning theories predict that embedding implicit regularities within a task should further improve online performance, beyond general practice. We challenged this assumption by contrasting performance in a visual search task containing either a consistent-mapping (regularity) condition, a random-mapping condition, or both conditions, mixed. Surprisingly, performance in a

Contour interpolation: A case study in Modularity of Mind

Cognition

Published in: Cognition, Volume 174, May 2018, 1-18 Abstract “In his monograph Modularity of Mind (1983), philosopher Jerry Fodor argued that mental architecture can be partly decomposed into computational organs termed modules, which were characterized as having nine cooccurring features such as automaticity, domain specificity, and informational encapsulation. Do modules exist? Debates thus far have been

Switching between lift and use grasp actions

Cognition

Published in: Cognition, Volume 174, May 2018, 28-36 Abstract “Switching between competing grasp postures incurs costs on speeded performance. We examined switch costs between lift versus use actions under task conditions that required subjects to identify familiar objects. There were no asymmetrical interference effects, though reliable costs occurred when the same object required a different action
