“…This is in contrast with research examining the effects of other anxiety induction methods where working memory capacity is limited by anxiety (Schoofs et al, 2008). Specifically, working memory capacity, not performance accuracy (however see Oei et al, 2006), is impaired by threatening pictures (Lindström and Bohlin, 2012), the cold pressor test (Schoofs et al, 2008; Duncko et al, 2009), and incidental changes in state anxiety (Walker and Spence, 1964; Firetto and Davey, 1971; Lapointe et al, 2013). In contrast to research using threat of shock, these findings are in line with processing efficiency theory (Eysenck and Calvo, 1992), which argues that anxious worry (1) reduces working memory processing capacity and (2) increases effort necessary to perform the task, thus increasing reaction time [although Duncko et al (2009) found decreased reaction time under stress].…”
