Visual observation is a fundamental skill underlying all occupational performance assessments in occupational therapy. The purpose of this study was to determine whether eye movement patterns differ between occupational therapists and non-healthcare professionals during observation of static images portraying a client post-stroke (domain-specific content) or naturalistic scenes (domain-irrelevant content). Ten licensed occupational therapists (OT group) and 10 participants matched for age, gender, and education level (NonOT group) completed the study. Participants viewed two counterbalanced blocks of 10 images (scene and stroke) under the pretext of preparing for a memory test. The OT group differed in the viewing strategies during observation and in how they directed their eyes (higher frequency of fixations, shorter fixation durations, and increased saccade count) for domain-specific and domain-irrelevant images alike. Observation patterns used by occupational therapists are presumably related to top-down influences that are not necessarily related to domain-specific knowledge but perhaps to general experience with performing assessments using observational methods.
