Document Summary
Input: info we receive from environment through our senses. Output: motor behaviour or action response to sensory input. Expanded conceptual model: input stimulus identification (perception) response selection (decision) response programming (action) output. Stimulus identification: what info is available and most relevant. Involves detection and processing of sensory info: result is representation of stimulus. Response selection: what options are available: selection of motor responses given task goals and nature of environment, transition b/w sensory input and motor output. Response/mvt programming: planning and generating chosen response: preparing motor system (brain stem and spinal cord) to generate desired response. Critical assumption that stages are non-overlapping (one stage complete before next) Reaction time (rt): diff in time b/w stimulus presentation and initiation of motor response (time of info processing) Movement time (mt): time elapsed from end of rt to completion of mvt. Response time: time elapsed b/w stimulus presentation and end of mvt (rt+mt) Measuring rts in lab: respond to any one of them.
