324 12 2 special topics timing

  1. 1. Human Learning Topic 12 - 2: Special Issues: TimingCEDP324 Ryan Sain, Ph.D. 1 3/30/2012
  2. 2. What is timing? Effects of stimuli are determined by durations or distributions in time Identifying that time has passed – and responding in a different manner Habituation, sensitization, spontaneous recovery Classical conditioning Operant conditioningCEDP324 Ryan Sain, Ph.D. 2 3/30/2012
  3. 3. Studying timing Timing as a biological process Environmental clues must be ruled out  Clocks ticking  Sun risingCEDP324 Ryan Sain, Ph.D. 3 3/30/2012
  4. 4. Timing techniques Duration estimation  Discrimination task  Sd is the duration of an event  Match to sample procedure Peak procedure  Sd presented  After specified time passes a response will produce Sr  Responding follows a generalization gradientCEDP324 Ryan Sain, Ph.D. 4 3/30/2012
  5. 5. Time out! Using a peak procedure 20 second peak 10 second delay  20 second No delay Introduce a break in the Sd  10 seconds  Sd only presented for 20 seconds total 10 20 30 40 The peak shifts by that amount of breakCEDP324 Ryan Sain, Ph.D. 5 3/30/2012
  6. 6. Theories Cognitive – Scalar Expectancy Theory  Pacemaker  Switch  accumulator (sums)  Send that info to working memory  Then compare that to the stimulus and decide if you should respond Behavioral  Adjunctive behavior (waiting behaviors)  Finger tapping, etc  Those occur in a particular pattern  After the pattern is complete the interval should be overCEDP324 Ryan Sain, Ph.D. 6 3/30/2012
