BIOC14H3 Lecture Notes - Lecture 9: Cognitive Deficit, Twin Study, Cognitive Test
Document Summary
Slide 3: what are some of the genetic influence on normal behaviour. Slide 5: one of the thing to look at is iq . Iq is a spe(cid:272)t(cid:396)u(cid:373) of the t(cid:396)aits: to test behaviour, we would use standardized rating scale (only real way to do this, standardized rating s(cid:272)ales a(cid:396)e f(cid:396)o(cid:373) e(cid:448)ide(cid:374)(cid:272)e .

If we go to the extreme end on the left side iq < (cid:1011)(cid:1004) is a(cid:271)out (cid:1006)% of populatio(cid:374) Slide 6: because of standard deviation of 15, the normal range is 85-115, anyone having iq of less than 85 is thought to have cognitive deficit.
