Exploration of the links between psychosocial wellbeing and face recognition skills in a French-speaking sample

Face recognition abilities vary tremendously in the general population. People at the lower end of the spectrum, those with developmental prosopagnosia, report stress, anxiety or social interaction issues due to their poor face recognition abilities. It isthus important to develop adequate diagnostic tools convenient to use for cliniciansand to examine relationshipsbetween face recognition skills and negative affects. In the present study, we provide a validated French translation of the 20-item prosopagnosia index(PI20), a self-report measure excellent at detecting people with face recognition deficits (Shah et al., 2015; Tsantani et al., 2021). We also examined links between face recognition skills measured with the PI20 and a standard face recognitiontest (Cambridge face memory test-CFMT;Duchaine & Nakayama, 2006) and measures of social anxiety (social interaction anxiety scale, social phobia scale) and negative affects(state trait anxiety scale, Beck depression inventory). We found a weak positive association between the PI20 and social interaction anxiety. Although this association is weakand warrantsfurther research, raising awareness about developmental face recognition issues may help improve the well-being of people with face recognition deficitsand provide new investigation orintervention avenues for clinicians who treat patients with social interaction anxiety.
