Background There is evidence that age and context (e.g. stimuli presentation) influence the way we perceive emotions (Barrett, Mesquita & Gendron, 2011; Stanley & Isaacowitz, 2015). We investigated whether there is an age‐dependent context effect on the perception of static facial emotions. Method In this cross‐sectional study, 240 cognitively and psychically healthy subjects (50% female), evenly distributed between 34 and 90 years old, participated. Two facial emotion intensity perception tasks (Chiu et al., 2016; Chui et al., 2018) comprising different stimuli presentations, were administered: In the congruent context , facial emotions (i.e., anger, fear, disgust, happiness and sadness) were rated on a seven point Likert scale in terms of intensity from 'not perceived' to 'very strongly perceived'. In the incongruent context each facial stimulus was shown consecutively five times and had to be rated not only on the congruent emotion, but also on the other four incongruent emotions (e.g., rating on happiness, anger, disgust, fear and sadness when a happy face was shown). Congruent scores of the two tasks were used to investigate the potential context effect on emotion perception. We performed a linear mixed effects analysis of each emotion, entering the interaction term age x context, sex and gender of the stimulus as fixed effects; subjects were treated as random effects. Result With increasing age, subjects perceived happiness (t(345) = 3.04, p < 0.01), disgust (t(717) = ‐6.42, p < 0.001, sadness (t(717) = ‐2.81, p < 0.001) and fear (t(717) = ‐2.13, p < 0.05) less intensely in the incongruent compared to the congruent context. In contrast, we found no age‐dependent context effect in the perception of anger. Conclusion We found a significant age‐dependent context effect in the perception of happiness, disgust, sadness and fear. Older subjects were more prone to context in terms of varying stimuli presentation than younger subjects, possibly also due to a decrease of cognitive functions in older age e.g., mental flexibility (Mather, 2016). Our results contribute to a better understanding of influential factors on emotion perception, which is critical when interpreting patients’ scores on an emotion perception task.
