Practise IB Psychology SL 2.2.4 by explaining research methods and evaluating how evidence supports conclusions about biological processes and behaviour in psychological studies.
Evaluate one model or theory of one cognitive process.
Refer to the paper 1 section B assessment criteria when awarding marks.
The command term "evaluate" requires candidates to make an appraisal by weighing up the strengths and limitations of one theory or model related to one cognitive process. Although a discussion of both strengths and limitations is required, it does not have to be evenly balanced to gain high marks. Candidates are not required to distinguish between a model and a theory.
Cognitive processes include, but are not limited to: memory, perception, language, or decision making.
A wide variety of models or theories may be presented which may include, but are not limited to:
- Working Memory Model (Baddeley and Hitch, 1974);
Levels of Processing (Craik and Lockhart, 1972);
The Multi-Store Model (Atkinson and Shiffrin, 1968, 1971)
- Chomsky's LAD theory (1957, 1968);
Skinner's Learning Theory (1957);
Bruner's Language Acquisition Support System (1983) related to language acquisition
- Flashbulb Memory Theory (Brown \& Kulik, 1977)
- Gregory's Constructivist Theory (1972, 1980);
Gibson's Theory of Direct Perception (1966,1979) related to perception
- Schema theory relevant to cognitive processes such as memory or decision making (Bartlett, 1932;
Loftus, 1974).
Evaluation of the selected model or theory may include, but is not limited to:
- degree of empirical support
- methodological considerations
- contrary findings or explanations
- involvement of other factors (for example, social or biological)
- application to real life.
If a candidate evaluates more than one model or theory, credit should be given only to the first model or theory. However, a candidate may address other theories or models and be awarded marks for this as long as these theories or models are clearly used to evaluate the main theory addressed in the response.
If a candidate addresses only strengths or only limitations, the response should be awarded up to a maximum of [ 5 marks] for criterion B, critical thinking, and up to a maximum of [2 marks] for criterion C, organization. Up to full marks may be awarded for criterion A, knowledge and comprehension.
