IB Psychology HL Internal Assessment Example

The student's investigation aim is focused and clearly tied to a real-world issue, so the reader immediately understands why the study matters.

The student's theory is mostly accurate and relevant to the investigation, and they use prior research to support the expected relationship.

The student's hypothesis is testable because both variables are operationalized in a way that can be measured directly.

The theoretical link to the procedure could be explained more precisely, especially how the effort heuristic should operate in this specific task.

The wording of the hypothesis could be tighter and more directly aligned with the analysis.

A little more clarity in the prediction would make the introduction easier to follow and more persuasive.

The student clearly identifies the experimental design and explains why it was chosen, including its value for reducing demand characteristics and supporting a cause-and-effect conclusion.

The student describes the sample well and justifies the participant choice in relation to practical access and language comprehension.

The student explains several material choices thoughtfully, especially the use of obscure abstract paintings and standardized instructions.

Some control features are not explained clearly enough, so the reader cannot always see exactly how the procedure kept conditions consistent.

Using ten paintings but analysing only one creates a control issue and raises concerns about order and artwork effects.

A few justifications are a little overstated or imprecise, such as the claim that the design prevents expectancy bias.
