Comparison of Deliberate and Spontaneous Facial Movement in Smiles and Eyebrow Raises

We investigated movement differences between deliberately posed and spontaneously occurring smiles and eyebrow raises during a videotaped interview that included a facial movement assessment. Using automated facial image analysis, we quantified lip corner and eyebrow movement during periods of visible smiles and eyebrow raises and compared facial movement within participants. As in an earlier study, maximum speed of movement onset was greater in deliberate smiles. Maximum speed and amplitude were greater and duration shorter in deliberate compared to spontaneous eyebrow raises. Asymmetry of movement did not differ within participants. Similar patterns contrasting deliberate and spontaneous movement in both smiles and eyebrow raises suggest a common pattern of signaling for spontaneous facial displays.

The Self at a Time of War in Northern Sri Lanka

The article takes one young Tamil woman, Vasantha, and her account of growing up in the northern war zone of Jaffna in Sri Lanka. Vasantha's narrative and her adolescence, like others of her generation, was framed by living at the margins of the Sri Lankan state (though under its bombardment) and under the control of a repressive quasi-state actor, the Liberation Tigers of Tamil Eelam (LTTE). In this article, I twin Vasantha's fashioning of her life-story with a meditation on the ways in which the Sri Lankan war, specifically LTTE control over Tamil lives, has come to ambivalently frame and produce particular understandings of selfhood, articulations of collectivity and individuality. Here, I argue that individuation takes many different forms, and, specifically, that the ruptures of war produces individuation in unexpected ways. I take Vasantha's story to explicate the experiences of young people in northern Sri Lanka, and, as an illustration of the contraction and expansion of particular possibilities of selfhood in the midst of political.
