Facial expression literature is vast and complex, and detection and processing of expressions is affected by both innate and environmental factors. Mental disorders can influence attention and previous studies have shown that one of the factors that might maintain an individual’s social anxiety is a bias toward threatening facial expressions. Recently, new studies have demonstrated how search is constrained by attention using a new task based on how animals forage food sources in the wild. Here, a new task based on those foraging models is introduced to investigate foraging for facial expressions and whether foraging differs based on scores on a screening test for social anxiety. Participants underwent six conditions where they searched for two types of targets amongst one type of distractor displayed on a tablet computer. The stimuli were 30 faces, each displaying one out of three types of expressions (happy, angry and neutral) facing either upright or upside down. The participants’ task was to tap, and thus remove, all the faces that displayed one of two types of target expression while ignoring the faces that displayed the distractor expression. An attention bias was found with inverted faces for participants with high social anxiety scores. Those participants located angry faces faster when they were targets and found other target expressions slower when angry faces were distractors. This task is an interesting addition to the face expression literature but needs to be explored further if definitive conclusions are to be drawn.
