    Perception of enjoyment and masking smiles with self-report measures of rating on scales from happiness to negative emotions
    (2016-04-08) Pelot, Annalie
    Previous studies explored individual’s judgment of masking smiles using dichotomous or categorical measures of rating which force individuals to categorize the masking smile into one discrete category. The current study further examined individuals’ ability to distinguish between enjoyment and masking smiles (smiles containing trace of negative emotion) with positive-negative dimensional rating scales. Thirty-two undergraduate students participated in the smile judgment study, which consisted an Enjoyment smile and six masking smiles: a smile with a trace of fear, of disgust, of anger in the brow, anger in the mouth, sadness in the brow and sadness in the mouth. Participants had to evaluate each smile with four different scales, which contained a positive and negative dimension (Happiness and either Fear, Sadness, Anger, and Disgust). Results indicated that participants could distinguish between the masking smiles and enjoyment smiles as they rated the enjoyment smiles more positively than the masking smiles. Participants were most sensitive to masking smiles containing traces of fear as they rated this expression more negatively compared to the other masking smiles. Other than the expression of anger (in the brow), masking smiles were rated more negatively overall than the genuine enjoyment smiles. Finally, response rates were quicker for enjoyment smiles than the masking smiles. Using dimensional measures of rating in the smile judgment task did not change individuals’ judgment of the masking smiles but may change the way the smiles are processed.

    Smile judgment in substance use disorders and its relationship to interpersonal and emotional functioning: an eye-tracking investigation
    (2018-09-05) Pelot, Annalie
    The current study explored the judgments individuals with Substance Use Disorders (SUDs) make regarding the authenticity of enjoyment smile expressions and masking smile expressions containing traces of negative emotions. Accuracy at identifying the masked negative emotions were also examined. Eye-movements were recorded to observe relationships between attentional processes and smile judgment. Additionally, the relationship between smile judgment, emotion dysregulation, and interpersonal problems were also investigated. Twenty individuals with SUDs being treated from a local treatment center and twenty individuals matched on gender/age participated in the smile judgment task, which involved a smile expression characteristic of enjoyment and six smile expressions containing traces of either fear, disgust, anger in eyes, anger in mouth, sadness in eyes, and sadness in mouth. Results indicated that individuals with SUDs were no different in their categorization of the smiles. The lack of difference may be due to their previously observed biases at interpreting expressions as negative, as the results indicated that individuals with SUDs were significantly more likely to report the presence of negative emotions in the expressions. They were also more often incorrect in their identification of the masked emotions. No link was observed between smile judgment and attentional processes. Emotional and interpersonal functioning were related more to the ability to distinguish smile authenticity than the ability to identify masked emotions.
