Question

1. Historically, a significant controversy in the field of biopsychology was the question of how our behavior is a result of nature (biology, genetics, inheritance) or a result of nurture (the environment we grow up in). Today, this is an obsolete position and it is believed by most that there is an interaction among genetics/biology and environment (or experience). The more accurate position is that behavior is due to an interaction between genetics/biology and experience.

2.Discuss this statement, citing relevant experimental evidence, in the context of at least one psychological behavior or disorder. For example, you could discuss visual perception, birdsong communication, learning, intelligence, aggression, obesity, mental disorders (anxiety, attention deficit hyperactivity disorder, depression, etc.), or another topic of interest to you.

3.Describe two types of biological/brain evidence (neurodevelopmental, genetic, neurotransmitter, imaging) for schizophrenia OR two types of biological/brain evidence for depression.
