Abstract Recognizing goal-directed actions is a computationally challenging task, requiring not only the visual analysis of body movements, but also how these movements causally impact, and thereby induce change in, those objects targeted by an action. We tested hypothesis that effects they relies on distinct neural representations in superior anterior inferior parietal lobe (SPL aIPL). In four fMRI sessions, participants observed videos (e.g. breaking stick, squashing plastic bottle) along with corresponding point-light-display stick figures, pantomimes, abstract animations agent-object interactions dividing or compressing circle). Cross-decoding between revealed aIPL encodes action effect structures independent motion object identity. By contrast, cross-decoding point-light-displays SPL disproportionally tuned to visible objects. Lateral occipitotemporal cortex (LOTC) was sensitive both movements. Moreover, pantomimes suggests right LOTC represent even response implied interactions. These results demonstrate are physical features, such as parts move space relative each other interact position shape/configuration).

This Element examines the influence of expectation and attention on conscious perception. It explores debate whether is necessary for perception by presenting empirical evidence from studies inattentional blindness, change attentional blink. While strongly suggests that perception, other research has shown can shape sometimes leading to illusory experiences where predicted stimuli are perceived despite their absence. phenomenon, termed 'expectation awareness', may not be all experiences. These findings explored within predictive processing framework, brain characterized as a prediction engine, continuously updating its internal models minimize errors. Integrating psychology, neuroscience, cognitive science, this provides model how construct perceptual reality. also discusses clinical theoretical implications future research.

Action Understanding DOI

Published: April 10, 2024

The human ability to effortlessly understand the actions of other people has been focus research in cognitive neuroscience for decades. What have we learned about this ability, and what open questions remain? In Element authors address these by considering kinds information an observer may gain when viewing action. A 'what, how, why' framing organises evidence theories representations that support classifying action; how way action is performed supports observational learning inferences people; actor's intentions are inferred from her actions. Further shows brain systems understanding, inspired 'mirror neurons' related concepts. Understanding vision a multi-faceted process serves many behavioural goals, served diverse mechanisms systems.

Abstract Being able to quickly recognize other people’s actions lies at the heart of our ability efficiently interact with environment. Action recognition has been suggested rely on analysis and integration information from different perceptual subsystems, e.g., for processing objects scenes. However, stimulus presentation times that are required extract about actions, objects, scenes knowledge have not yet directly compared. To address this gap in literature, we compared thresholds First, 30 participants were presented grayscale images depicting variable (33–500 ms) provided written descriptions each image. Next, ten naïve raters evaluated these respect presence accuracy related scenes, sensory information. Comparing across times, found recognizing shorter (from 60 ms onwards) than (68 (84 ms). More specific approximately 100 ms. Moreover, modulated by action category, lowest locomotion highest food-related actions. Together, data suggest evidence is gathered parallel when same scene but accumulates faster reflect static body posture
