NEW335H1 Lecture Notes - Lecture 7: Verbal Fluency Test, Neuroplasticity, Job Performance
Document Summary
Stm: temporary storage ->lost, rehearsal -> store in ltm, 7+/- items, impairment related with many pathologies, relate with job performance. Dlpfc (dorsolateral prefrontal cortex): meditation induced neuroplasticity, verbal fluency, digit symbol modality task. Changing attitude about job is more important: meditation improved how they feel about the job and that lead improvement in performance. Stress and wm -> too much stress -> impair wm. Certain amount of stress is positively effective to performance. Too little or too much stress leads to poor performance. Stress: -> sns -> ep, ne, -> pns -> cortisol. Gcs modulates neuron"s communication: modest levels of gc is optimal for synaptic strengthening, higher stress ->higher gcs -> poorer learning. Long-term potentiation is an increase in synaptic strengthening. Ospan test: problem (math questions) -> solution -> letter, impaired memory: people cannot remember letter by distracted by math problems, meditation -> improved performance by less distracted. Ospan graph: (-) negative numbers indicate: suffering by impaired wm from stress.
