ABSTRACT: Cognitive impairment is a
symptom of schizophrenia and strongly associated with impaired social function.
In recent years, cognitive interventions (cognitive remediation therapies) have
been implemented and their results have also been reported. Intervention
studies have been conducted using a variety of methods that differ in terms of
terminology, approach, and targeted cognitive domains. In this study, we
examined trends in recent cognitive remediation research conducted subsequent
to the meta-analyses of McGurk et
al. (2007) and Wykes et al. (2011). We identified studies
conducted between 2009 and 2013 to examine computer-assisted cognitive
remediation and collated and analyzed the literature describing their major
results and trends. Our results indicated improved cognitive performance
subsequent to cognitive remediation therapy using computer programs. We found
promising outcomes, particularly in reasoning and problem solving, verbal
learning and memory, verbal working memory, and attention and vigilance, which
replicated the findings of Wykes et
al. (2011).
