Abstract
Facial expressions of emotions are regarded as ‘Crown Jewel’ of nonverbal communication (Mandal & Awasthi, 2014). This study used a
computer based emotion recognition task to compare individuals with
Substance Use Disorder (SUD) with normal controls to investigate their
ability to recognize facial expressions of six basic emotions (Ekman,
1982) and associated average reaction time to recognize these emotions. A
sample comprised 58 men with SUD with means age of 28.66 (SD = 4.90)
and 50 matched normal controls with mean age of 28.62 (SD = 4.79).
Based upon studies (e.g. Leshner, 2001, Volkow, 2009) it was assumed
that if SUD bring changes in structure and function of brain the emotion
recognition ability and average reaction time of the two groups will differ
significantly. Between-Within ANOVA indicated that normal controls
were significantly better and took significantly lesser average reaction
time to recognize facial expressions of emotions as compared to
individuals with SUD. The results are discussed in the socio-cultural
context of Pakistan.
