Figure 1.

Examples of PALM trials and feedback for incorrect and correct answers. An incorrect answer choice (A) is followed by feedback showing the incorrect choice highlighted in red and the correct choice highlighted in green (B) along with a verbal description of the criteria for the correct interpretation and arrows and parallel lines to draw attention to features and magnitudes of differences relevant to the interpretation of the tracing (and arrowheads indicating variable features). In the case of a correct answer (C), the response time is also indicated and only the correct answer is highlighted. See Results for a more detailed discussion of this figure. PALM = perceptual and adaptive learning module.
