Perception and Motor Actions

Imaginal Module

---

• All requests to the imaginal module through the imaginal buffer are requests to create a new chunck.
• The Amount of time it takes to create a chunk = 0.2 sec

      (p encode-letter
         ...
         ?imaginal>          ; //query imaginal to verify if it is available
           state free
       ==>
         ...
         +imaginal>             ;// send request to imaginal to create a new chunk
           isa array
           letter =letter
  

  Vision Module

  ---

• can parse text, lines, button features from the displays created.
• tow buffer :
• visual-location

    (p find-location
      ...
    ==>
      +visual-location>  
        :attended nil  ;// request for a location which the model has not attended
      :attended t    ;// request for a location which has been attended previously
        :attended new    ;// the model has not attended to the location and the object has also recently appeared in the visual scene
      ...
    )
  

• visual

    (p attend-letter
      =goal>
        ...
      =visual-location>   ;// if there is a chunk in the visual-location buffer
      ?visual>            ;// query visual buffer if it is available for a new request
        state free
    ==>
     +visual>     ;// move attention to the location specified in visual-location
        cmd         move-attention
        screen-pos  =visual-location
      =goal>
        ...
  

• for visual-location buffer of vision module, there is no time involved in handling the request (in such case, no need to query), reflects the assumption that there is a perceptual system operating in parallel within the vision module.
• the state of vision module for the visual-location buffer is always free.
