Theories on Practice with TBI patients

Question 1

Theories for Memory

Answer 1

Concept of Modularity - faculties are seperated into different neural areas of the brain.

Neo-Lashley Hypothesis - patterns, coordinated action of wide areas

Distributed Model Theory - neural imaging, hot spots in brain

Modern Theories

          a. encoding
          b. consolidation
          c. storage
          d. retrieval

Question 2

Theories on Attention - Theories of Selection

Answer 2

1) Dichotic Listening Tasks led to Early Filter Theory - listen to info w/ 2 different sounds in both ears. we decide what’s important. People could decide what info to respond to in non-intended ear.
2) Filter Attenuation Model - maybe early filtering but not completely shutting off one channel.
3) Late Filter/Late Selection Model - incoming stimuli are fully analyzed and processed. Filtering happens before we want something else to draw our attention

Question 3

Theories of Attention - Theories of Capacity Limitation

Answer 3

Resource Allocation Theory - lots of resources but hard to remember where (pledge of allegiance and sort cards) we do simultaneous things but pick what’s most challenging and prioritizing.

Multiple Resource Capacities - specialized resources with visual and auditory processing.

Central Bottleneck Model - our response selection can only be for 1 task at a time. Back and forth switching between 2 tasks.

Question 4

Posner and Peterson’s Subsystems of Attention

Answer 4

Alerting - state of readiness to process amd respond to incoming sensory information

Orienting - functions to enhance processing of stimuli in a particular location. Giving more structure to a task. (visual orienting)

Executive Control Network - target selection and detection, alerting to task, have to make a decision.

Question 5

Mateer and Sohlberg’s Clinical Model

Answer 5

1) Selective Attention - avoid distraction
2) Alternating Attention - shifting, moving from 1 task to another ( concussion)
3) Divided Attention - engage in multiple tasks simultaneously, (concussion)
4) Focused Attention - basic low level activity to respond to a stimuli.
5) Sustained Attention - hold info in mind that’s necessary to perform a task. vigilance to remain focused.
