THE ACTION PERSPECTIVE - Coggle Diagram
THE ACTION PERSPECTIVE
VISUAL WORKING MEMORY AND ACTION
Introduction
vWM planned flexible behaviours
Not only for vision
Bidirectional link with (planned) action
Functional links
vWM serves perspective actions
Previous study differentiate what and how to search
Studies about direct action control doesn't consider visual detailed informations
Retention as one specific function
New visual-motor working memory task
Demonstrated parallel action planning
Actions invoke vWM
Imposing need for vWM
Requiring visual information
Actions activate visual brain areas
Eye movements but not only
Mutual involontary influences
vWM influence actions
Task irrilevant stimuli attract our eye movements
Eye movements triggered by selecting in vWM
Actions influence vWM
vWM task when target - action congruent location
Also manual pointing
Feature-dimension prioritization
Shaping in a non-adaptive way in the task
NAVIGATING THE AFFORDANCE LANDSCAPE
Human Cognition from the Perspective of Feedback Control
Overcoming sense-think-act
Brain as feedback control system
Not informing about world
Yes acting in the world to mantain some parameters controlled
Hierarchical Affordance Competition
Brain decides between a set of actions
Continuous process
Action as region in a continuous landscape of actions
Internal action as navigating in this
Decision-Making within a Hierarchy of Control Loops
Parallel elaboration in the higher/lower-levels
Distribuited elaboration
Continue (re)creation of affordances
Action Control within a Hierarchy of Control Loops
Higher-level choose goal to pursue
Lower-level choose in autonomy the action to reach the goal
Discussion about bottom-up and top-down processes
Brain Mechanisms Supporting Hierarchical Affordance Competition
Reflection of "decision and action space" in brain physiology
Parallel lower-level and cortico-cerebellar loop
Not classic vision of lower/higher levels
Not classic distinction of cognitive/movement areas
Behaviour towards specific goals
always control
Higher-level and reuse neural resources
Thinking as prediction and imagination
