  1. Psychology 127: Lecture 1

  2. Housework On-line error w/ section times. ** Cogsci had wrong time listed on Friday but it has been fixed. Class Adds: Via Waitlist (details at end of class). Must be opening in section. Openings mainly in Friday 10 and Friday 2 sections. Prereqs and overlap with other courses Recommend one of Psych 110, 120, Cogsci 1, 100 Relationship to MCB 61: Mind, Brain, and Behavior Too much overlap with Psych 117: Human Dysfunction Exam conflict w/ 120 and 126 is minimal!

  3. Housework Lecture notes: http://socrates.berkeley.edu/~ivrylab/psych127_2008 Before class posted w/ filename+preview After class re-posted in final form. Sections: NO Sections this week. For next week: Prepare Reader #1 Posted on website. Attendance is required!

  4. Housework Syllabus Posted on website Show on screen

  5. Housework CognAC RA's needed! See Ivry lab website for description and application. http://ist-socrates.berkeley.edu/~ivrylab/ (or just google me and first link is it)

  6. Cognitive Neuroscience: The Biology of the Mind • Integration of (at least) four disciplines: • Neurology: Function and pathology of the nervous system • Neuroscience: Mechanisms of the nervous system • Includes • neuroanatomy • neurophysiology • neurochemistry • Cognitive psychology: How the mind processes information • Computer science/Artificial intelligence: • How can computers perform tasks • Can we simulate mental behavior from neural-like models.

  7. Behavioral Neurology • Emphasis on linking brain parts to different tasks • e.g., language and the left hemisphere • coordination and the basal ganglia

  8. Diagram Making (Early Behavioral Neurology)

  9. Behavioral Neurology • Emphasis on linking brain parts to different tasks • Important for clinical evaluation and treatment • Predicting recovery from language problems after a stroke. • Prescribing medication for elderly person who shows onset of coordination problems.

  10. Behavioral Neurology Task-based analysis is limited for explaining normal mental activity. What do we learn about language from knowledge that left hemisphere is more important than right hemisphere for speech comprehension and production? Or, given knowledge about pathology in Parkinson’s disease, how the basal ganglia contribute to motor control?

  11. Cognitive Psychology • Provide detailed analysis of how information is processed when we perform a complex task

  24. Cognitive Psychology • Provide detailed analysis of how information is processed when we perform a complex task • Does reading involve a conversion of visual information to phonological (auditory-based) representations? • Or are skilled readers able to directly process the entire word?

  25. Cognitive Psychology • Provide detailed analysis of how information is processed when we perform a complex task • Does reading involve a conversion of visual information to phonological (auditory-based) representations? • Or are skilled readers able to directly process the entire word? • Cognitive models can be proposed without considering biological issues

  26. A Cognitive Model of Reading

  27. Cognitive neuroscience Interdisciplinary effort to relate mental processes to brain structures. Interaction is bidirectional Specify functions of different brain structures: Example: What can we learn about brain function by using language tasks? What neural areas are important for converting visual words into phonological (sound) representations.

  28. Cognitive neuroscience Interdisciplinary effort to relate mental processes to brain structures. Interaction is bidirectional Specify functions of different brain structures. Develop models of cognition. Example: What can we learn about language by studying how communication skills change following brain damage or by observing physiological activity in the brains of healthy people when performing language tasks?

  29. Models lead to predictions: Suppose we know where the letter to sound translation process is located (from a brain imaging study). If a person has a stroke that destroys that area, what kind of reading problems might we expect?

  30. Models lead to predictions: Damage to letter-sound conversion should not affect ability to read both regular and irregular words. But there should be a big problem with nonsense word-like letter strings. CAN CAN’T cave cive have hove ghost gote pulley lutpig

  31. Emergence and development of cognitive neuroscience is method driven. New technologies to image the nervous system polysynaptic tracers: cellular fMRI, DTI : systems New technologies to manipulate the nervous system Genetic knock-outs TMS First set of lectures will review these methods.
