IB Psychology/Levels of Analysis/Biological Level

Biological Level 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.
