“…Stroop interference is believed to occur when automatic processing of threatening words reduces the speed of color naming (Watts, McKenna, Sharrock & Trezise, 1986). Stroop bias is frequently described as attentional bias (e.g., Williams et al, 1996) but other authors have argued that the task cannot distinguish between selective attention, inhibitive emotional responses, mental preoccupation, or cognitive avoidance for Stroop words (Bögels & Mansell, 2004), so is perhaps best thought of simply as a processing bias (Nightingale, Field & Kindt, 2010). The emotional Stroop task is argued to be a useful measure of psychopathology (e.g., Williams et al, 1996) and evidence suggests that, for example, adults with social anxiety show a Stroop processing bias for socially threatening stimuli (see Bögels & Mansell, 2004;Ledley & Heimberg, 2006, for reviews).…”
