1. Introduction to the Biological Level of Analysis
IB Psychology SL

2. Principles the Define the Biological Level of Analysis
Reject the idea that the mind exists independently of the physical brain.
EVERY TIME YOU THINK… YOUR BRAIN IS DOING SOMETHING IMPORTANT!
Behavior is the result of a biodirectional process.
Biology and the Environment influence each other in a reciprocal relationship.

3. Principles the Define the Biological Level of Analysis
Animal models establish a base from which to consider human behavior.

4. Biological Level- Learning Outcomes
General Outcomes
Outline principles that define the biological level of analysis
Explain how principles that define the biological level of analysis may be demonstrated in research.
Discuss how and why particular research methods are used at the biological level of analysis.
Discuss ethical considerations related to research studies at the biological level of analysis.

5. Biological Level- Learning Outcomes
Physiology and Behavior
Explain on study related to localization of function in the brain.
Using one or more examples, explain effects of neurotransmission on human behavior.
Using one or more examples, explain functions of two hormones in human behavior.
Discuss the effects of environment on physiological processes.
Examine one interaction between cognition and physiology in terms of behavior. Evaluate two relevant studies.
Discuss the use of brain imaging technologies in investigating the relationship between biological factors and behavior.

6. Biological Level- Learning Outcomes
Genetics and Behavior
With reference to relevant research studies, to what extent does genetic inheritance influence behavior.
Examine one evolutionary explanation of behavior.
Discuss ethical considerations into genetic influences on behavior.

18. What does the Endocrine System Do?

19. Hormones Hormone Gland Action Testosterone / Estrogen Testes/ Ovaries
Controls puberty and sext production.
Anti-diuretic hormone (ADH)
Pituitary gland
Controls blood water level by triggering uptake of water in the kidneys.
Cortisol
Adrenal gland
“stress” hormone
Thyroxine
Controls metabolic rate.
Adrenaline
Prepares body for action (fight-or-flight)
Glucagon
Pancreas
Controls blood sugar levels by decreasing uptake of glucose.
Insulin
Controls blood sugar levels by increasing uptake of glucose.
