 * Interactionist Approach || An approach which does not rely solely on either nature (biological) or nurture (enviornment), but adopts a more holistic picture of human behavior
 * Reductionist || An approach which is often adopted by biological researchers to the study of human behavior as it is a micro-level for research, which breaks down complex human behavior into its smallest parts. (ex. focusing on the role of a gene, a neurotransmitter, or a protein) ||

__Summary of the Biological Level of Analysis__
- Physiological origin of many behaviors - **Bidirectional Relationship** - Biology can affect cognition and cognition can affect biology

- Physiological factors (brain processes, neurotransmitters, hormones, and genes) can affect behavior Physiology responds to environmental stimuli (ex. stressful experience, an attractive person walking by, or extreme brain damage caused by an accident.) - One of the major controversies = **Nature Versus Nurture Debate** - Modern psychologists (//goal of IB psychology//) = **Interactionist Approach**

- Biological researchers: **Reductionist** approach = Micro approach - sometimes criticized : overly simplistic in explaining behavior - //Important// to have detailed knowledge of the compontents of human behavior = //understand// how several factors may interact to cause certain behaviors __No easy answer to complex questions.__

= __ The Principles About Human Behavior __ =

1) Behavior can be innate because it is genetically based
(evolution)

2) Animal research can provide insight into human behavior
(significant amount of research is undertaken using animals)

3) Biological correlated of behavior
(link between a specific biological factor and a specific behavior) Remember: Gene The Tumorous Rat Ate Her Parents
