Isolating neural components of threat bias in pediatric anxiety

Abstract: Background Attention biases towards threat are often detected in individuals with anxiety disorders. Threat biases can be measured experimentally through dot-probe paradigms, in which individuals detect a probe following a stimulus pair including a threat. On these tasks, individuals with anxiety tend to detect probes that occur in a location previously occupied by a threat (i.e., congruent) faster than when opposite threats (i.e., incongruent). In pediatric anxiety disorders, dot-probe paradigms detect abnorm… Show more

“…To date, fMRI research using the dot-probe task yields generally consistent findings (Britton, 2012; Fani et al, 2012; Monk et al, 2006, 2008; Telzer et al, 2008). On this task, individual differences in anxiety relate to perturbed function in brain regions supporting emotional processing (e.g., amygdala) and attentional control (e.g., ventrolateral prefrontal cortex, vlPFC; dorsolateral prefrontal cortex, dlPFC).…”

“…Moreover, in these imaging studies, some findings emerge for contrasts comparing angry incongruent (different spatial location) and angry congruent (same spatial location) trials (i.e., the Attention Bias to Threat contrast). These studies find that anxiety is associated with greater amygdala (Monk et al, 2008) and greater lateral PFC activation (e.g., Britton et al, 2012; Telzer et al, 2008). Other findings emerge when examining neural activation to any threatening facial expression, collapsing across congruency, compared to neutral facial expressions on the dot-probe task (Monk et al, 2006).…”

“…Studies examining the neural correlates of AB in relation to anxiety commonly employ the dot-probe task (Bar-Haim et al, 2007), in which each trial presents a pair of faces (either both neutral, or a neutral-threat pair) followed by a probe replacing one of the faces (youths: Britton et al, 2012; Monk et al, 2006; 2008; Price et al, 2014; Telzer et al, 2008; adults: Fani et al, 2012; Hardee et al, 2013). Biased attention toward threat is quantified behaviorally in the neutral-threat trials by slower reaction times (RTs) to the probes that replace the neutral face (incongruent trials) compared to the probes that replace the threat face (congruent trials).…”

“…Although there is also experimental evidence for a vigilance-avoidance pattern of attention to threatening stimuli in anxious youth (In-Albon, Kossowsky, & Schneider, 2010), the pediatric literature is mixed with many reports of threat vigilance in anxiety (Dalgleish et al, 2003; Roy et al, 2008; Taghavi, Neshat-Doost, Moradi, Yule, & Dalgleish, 1999; Vasey, Daleiden, Williams, & Brown, 1995; Waters, Henry, Mogg, Bradley, & Pine, 2010; Waters, Mogg, Bradley, & Pine, 2008), but also several reports of threat avoidance (Britton et al, 2012; Brown et al, 2013; Monk et al, 2006). More work is needed to determine whether the mixed pediatric literature is partly a result of threat vigilance in studies that measure threat bias at short durations and threat avoidance in studies that measure threat bias at long durations.…”
