摘要：The case series approach to cognitive neuropsychology allows for theories that make quantitative predictionsabout functional associations to be tested (Schwartz & Dell, 2010). But even if these associations are observed, theremay be individuals who significantly deviate from the predictions of the association. These outliers may reveal thelimitations of the theory being tested and provide an opportunity to develop a better one. I discuss a recent caseseries that used a single outlying individual to address the causes of letter perseveration in spelling (Fischer-Baum &Rapp, 2012) to illustrate this point.
