IB Psychology/Levels of Analysis/Biological Level


Biological LevelEdit

The biological level is the observation of the physical aspects of the brain, such as physiology and chemicals. There are 3 overarching headings in the biological level, which together contain 14 learning outcomes, of which 8 are essays and 6 are 8 marks.

General Learning Outcomes
GLO1: Outline principles that define the biological level of analysis.
GLO2: Explain how principles that define the biological level of analysis may be demonstrated in research.
GLO3: Discuss how and why particular research methods are used at the biological level of analysis.
GLO4: Discuss ethical considerations related to research studies at the biological level of analysis.
Physiology and Behaviour
PB1: Explain localisation using a key study as an example.
PB2: Explain one study related to localisation of function in the brain.
PB3: Using one or more examples, explain effects of neurotransmission on human behaviour.
PB4: Using one or more examples, explain functions of two hormones in human behaviour.
PB5: Discuss two effects of the environment on physiological processes.
PB6: Examine one interaction between cognition and physiology in terms of behaviour. Evaluate two relevant studies.
PB7: Discuss the use of brain imaging technologies in investigating the relationship between biological factors and behaviour.
Genetics and Behaviour
GB1: With reference to relevant studies, to what extent does genetic inheritance influence behaviour?
GB2: Examine one evolutionary explanation of behaviour.
GB3: Discuss ethical considerations in research into genetic influences on behaviour.
