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
Angelika Lingnau, Paul E. Downing

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.

Humans are good at picking up statistical regularities in the environment. Probability cueing paradigms have demonstrated that location of a target can be predicted based on spatial regularities. This is assumed to rely flexible priority maps influenced by visual context. We investigated whether stimulus features such as color distributions differing mean and variance cue In experiment 1, participants searched for an oddly colored diamond 6 × set. On each trial, distractors were drawn from one two centered different averages. Each distribution was associated with probabilities, where had 80% chance appear left (the rich location), while would right other distribution. Participants significantly faster locating when it appeared both distributions, demonstrating learning relationship between average probability. experiments 2 3, observers performed similar search task, but variances same color. There no evidence became location, suggesting contingencies probabilities not learned. These results demonstrate how flexible, contexts leading maps, they also reveal important limits learning.
