PSYC31H3 Lecture Notes - Lecture 8: Closed Head Injury, Whist, Short-Term Memory
Document Summary
Behavioral expression of diffuse brain injury (most deficit to least: hierarchy of deficits, sustained attention dysfunction, concentration (focus) dysfunction, memory dysfunction. Can consolidate and retrieve, but limited: impaired higher level and complex reasoning resulting in conceptual concretism and inflexibility. Executive functioning (i. e. problem solving, planning, etc. : general response slowing exacerbates all test scores. Compromised test scores due to slowed information processing and movement. Due to poor attention and slowed information processing, repetition helps consolidation, thus patients improve over trials (initially do poorly at the beginning of learning a list of words but improve) Making test part a: due to slowed information processing speed will perform accurately, but slowed on attentional tasks (e. g. trail. Tower of london, bads, wcst, phonemic fluency, ruff 2&7, and trail making test part b: left temporal lobe: Defective verbal performance: errors increase since harder to divide attention than sustain attention.
