Naturalistic stimuli reveal a dominant role for agentic action in visual representation

James V. Haxby, M. Ida Gobbini, Samuel A. Nastase
2020 NeuroImage  
These domains include perception and understanding of agentic action, which plays a larger role in visual representation than was appreciated from experiments using static, controlled stimuli.  ...  The use of naturalistic stimuli enables functional brain imaging research to explore cognitive domains that are poorly sampled in highly-controlled experiments.  ...  Studies using naturalistic, dynamic movies reveal that agentic action plays a surprisingly dominant role in visual representation.  ...

What Does Dorsal Cortex Contribute to Perception?

Erez Freud, Marlene Behrmann, Jacqueline C. Snow
2020 Open Mind  
However, growing evidence suggests that the dorsal pathway also plays a functional role in object perception.  ...  As such, we consider whether naturalistic stimuli, such as real-world solid objects, might engage dorsal cortex more so than simplified or artificial stimuli such as images that do not afford action, and  ...  Finally, we propose a new perspective on dorsal cortex function that centers on the premise that the potential for action offered by visual stimuli in naturalistic visual environments might shape the computations  ...

A Naturalistic Approach to the Hard Problem of Consciousness

Wolf Singer

Where's the action? The pragmatic turn in cognitive science

Andreas K. Engel, Alexander Maye, Martin Kurthen, Peter König
2013 Trends in Cognitive Sciences  
From representation to action Since its formation as a discipline that aims for a naturalistic account of the mental, cognitive science has been dominated by a view of cognition as computation over mental  ...  than on investigating their dependence on external stimuli -a view that has been dominating classical neurophysiology for decades.  ...

Neuronal bases of structural coherence in contemporary dance observation

Asaf Bachrach, Corinne Jola, Christophe Pallier
2016 NeuroImage  
Hence, much attention has been given to the Action Observation Network (AON) whereas the role of other potentially relevant neuro-cognitive mechanisms such as mentalizing (theory of mind) or language (  ...  An ROI analysis based on a similar study using linguistic materials (Pallier et al. 2011 ) suggests that structural processing in language and dance might share certain neural mechanisms.  ...  We thank Amandine Bajou and Margot d"Orleans for the creation and execution of the dance phrases and Loic Nys for taping and editing the stimuli.  ...

Just one look: Direct gaze briefly disrupts visual working memory

J. Jessica Wang, Ian A. Apperly
2016 Psychonomic Bulletin & Review  
The present study provides the first evidence that direct gaze impairs visual working memory with a rapidly-developing yet short-lived effect even when there is no need to attend to agents' gaze.  ...  Experiment 1 revealed that, despite the irrelevance of the agents' eye gaze to the memory task at hand, participants were worse at detecting changes when the agents looked directly at them compared to  ...  any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.  ...
