Chapter 234(Pool et al., 2016). To systematically investigate biased attention to certain stimuli, namely biases to threat stimuli in individuals with a depression or anxiety disorder, the dot-probe task was developed (MacLeod et al., 1986). Since then, it has been used to investigate a variety of biases to a variety of stimuli in different populations (see van Rooijen et al., 2017). While the specific content and parameters differ between studies, they all share the general structure: a trial starts with the presentation of two stimuli for a pre-specified duration on two sides of the screen and equidistant to the centre. After they disappear, a probe appears on one of the two picture location which the participant has to react to. If the target stimulus (e.g., an emotional one) is replaced by the probe, the trial is defined as %u2018congruent%u2019. In contrast, in an %u2018incongruent%u2019 trial, the probe appears on the location of the control stimulus (e.g., a neutral one). The attentional bias is then usually calculated by looking at a difference value between reaction times during congruent and incongruent trials. Studies looking at attentional biases to emotional facial expressions using this task have reported attentional biases to both positive (e.g., Wirth & Wentura, 2020) and negative facial emotional expressions (e.g., Bradley et al., 1997; Carlson & MujicaParodi, 2015). However, when contrasting different emotion categories in the dotprobe task, some studies only found a bias towards specific emotions (e.g., Valk et al., 2015) while other studies found no bias in reaction times at all (e.g., Puls & Rothermund, 2018). Methodological differences between studies, for example, in the timing of the stimuli or the stimulus content have been suggested as potential explanations for the mixed evidence (Cooper & Langton, 2006; van Berlo et al., 2020). Importantly, inconsistent findings can also be driven by individual differences (Yiend, 2010). For example, an altered processing of emotional (facial) stimuli, including attentional processes, has been described in various mental health conditions (Kret & Ploeger, 2015). Attention to Emotion in Social AnxietyBeing characterized by a disproportionate and impairing fear of scrutiny in social situations, Social Anxiety Disorder (SAD) is a mental health condition that already suggests altered attentional allocation to social information by definition (DSM-V; American Psychiatric Association, 2013). The most prominent cognitivebehavioural models on the development and maintenance of SAD all describe a shift in attention to the self as a social object once a social situation is entered or
