(11) Jan 20, Decision making (hs)

Topics addressed in the lecture:

  • Features influencing decision making
  • Different types of choose tasks
  • ROC analysis as a measure of decoding capability
  • Dependence of choice by target frequency, expected value, and stimulus timing
  • Biased competition model of decision making
  • Influencing decisions with neural stimulation
  • Examples from neuro-economics

Examples for question you should be able to answer:

  • What is the difference between a perceptual discrimination task and a free-choice task?
  • What do psychometric and neurometric performance curves describe? Which one is related to ROC analysis?
  • Describe the neural activity in parietal cortex during a free-choice task (matching behavior or variation of SOA)? What does the neural activity represent?
  • What is the difference between risk-neutral and risk-aversive behavior?

Important concepts:

  • perceptual discrimination and a free-choice behavior
  • psychometric and neurometric performance
  • choice bias by target frequency, reward, and timing
  • biased competiton model for decision making
