IB Psychology HL Internal Assessment Example

You clearly stated a focused investigation aim and showed why it mattered both theoretically and in a real-world context.

You described the dual-processing model accurately enough to support the investigation and linked it to the expected effect of font disfluency.

You identified, stated, and operationalized both variables well, making the hypothesis testable.

The theory link would be stronger if you avoided implying that reflective thinking only occurs when intuitive thinking fails.

The rationale for the study could be even sharper by making the exact connection between the model and the font manipulation more explicit.

You clearly described the independent-samples design and explained why it was suitable for avoiding practice effects.

You identified the sampling approach and participant characteristics in enough detail to show how the study was carried out.

You explained several key controls and materials in a way that shows awareness of validity threats.

There is an internal inconsistency in the stated timing of the task, which weakens confidence in the procedure.

Some choices of materials and controls would benefit from clearer justification, especially how they suited the CRT and the sample.

The explanation of allocation to conditions would be stronger if it were stated more directly in the main procedure.
