Visual Approach For Emotional Processing

Decent Essays
The present study also employs a visual adaptation paradigm to test emotional processing in anxiety. Facial stimuli were taken from the same database as that of Richards et al (2013). The expressions used in this study were fearful faces, neutral faces and morphs containing 50% neutral and 50% fearful expression. Contrary to the above, the present study only included adaptation trials wherein the participants had to make a response. The nature of the adaptation trials in the current study was similar to that of Richards, Holmes, Pell & Bethell’s study (2013). The morph was presented after a certain context, which was either a fearful or a neutral facial expression. Participants were required to classify the morph as being either fearful or neutral. It was predicted that participants would perceive the morph as being fearful if the context was neutral and neutral if the context was fearful. A feature unique to the present study was the introduction of double adaptor trials, which included two adaptor faces. These pairs of adaptor faces could either be both fearful, both neutral or one fearful and one neutral. Therefore, the context was of two broad types; in one block the context was a single face whereas the context was a pair faces in the other block. We were interested to see if the magnitude of adaptation was stronger with a single adaptor or with double adaptors. The former would show a greater perceptual overlap since the target replaces the adaptor in the same position
