IB Psychology SL Internal Assessment Example

You stated a clear, focused aim and explained why the investigation matters for eyewitness testimony.

You described the relevant theory of reconstructive memory and linked it directly to the manipulation in your study.

You correctly identified and operationalized both variables in a way that made the hypothesis testable.

Your hypothesis could be even sharper if the unit for the dependent variable was repeated with complete consistency.

Some of the theoretical wording could be slightly more cautious so it reads as interpretation rather than certainty.

You explained the experimental design clearly and gave a good rationale for using an independent-measures approach.

You identified the sampling method and participant characteristics, and you explained why this sample was practical for the investigation.

You described the controlled materials and procedure well, and often linked those controls to fairness and validity.

Your explanation of random allocation is not fully convincing, since being in different classes is not the same as individual random assignment.

A few control points need more careful justification, especially where you imply that balance alone controls participant differences.

Some procedural choices, such as the response window, could be explained more fully to strengthen the design rationale.
