The student incorporates relevant and appropriate source material throughout the essay, effectively addressing the research question regarding theory of mind (ToM) impairments and social functioning in schizophrenia. They utilize a range of accredited scientific sources, including key studies and meta-analyses, which enhances the credibility of their analysis. However, the student does not consistently explain technical or subject-specific terms, particularly regarding schizophrenia, which limits the reader's understanding of the topic. Despite this, the essay includes a thorough evaluation of empirical studies, maintaining an academic tone and analytical style throughout. Overall, the student's integration of sources is commendable, though clarity in the explanation of technical terms could be improved.
