“…Nonfocal tasks have been shown to require more cognitive resources than focal tasks (e.g., Brewer, Knight, Marsh, & Unsworth, 2010;McDaniel & Einstein, 2000). Accordingly, a relationship between working memory and PM performance has been shown for nonfocal tasks only (e.g., Brewer et al, 2010;Rose, Rendell, McDaniel, Aberle, & Kliegel, 2010). Thus, the results obtained by Altgassen et al (2009) suggest that depression-related PM impairments are more likely when the task requires relatively high amounts of cognitive resources as is the case with nonfocal tasks and multiple targets.…”
