PSYCH 212 Lecture Notes - Lecture 3: Robert Plomin, Shy Child, Negative Feedback
Document Summary
A way of looking at the strength of heredity. Mz twins are highly concordant on most traits. Demonstrate that genes and environment often reinforce each other (robert plomin) Trying to get estimates that quantify how we affect our environment and how our environment affects us. 3 types: (1) passive correlations: we share genes with out biological parents with whom we also tend to share a physical environment. From viewpoint of baby usually applies to ~birth to around 5 years old~ Also pass on genes that are related to musicality/ reading (2) reactive/evocative correlations: different aspects of genetic predisposition can create a reactive environmental situation (good or bad) Usually starts to be seen in kids around preschool/kindergarten ~4-5 years old~ Shy child(g): encouraged to come out of their shell(e). Negative feedback because he went against his genetics less than what he started with.
