AbstractThis thesis investigated the interaction of stress and decoding accuracy through the vocalic and facial kinesic channels and with regard to gender. Stress (high and low) was created for 372 undergraduate students using the Stroop Color-Word Test. Overall, results did not show that an increase in stress led to a decrease in decoding accuracy. However, the findings did suggest that stress was impacting on the decoding process. The researcher uncovered a main effect for channel such that the facial kinesic channel was the most accurate for decoding emotions. In addition, an ordinal interaction was found during the first time period which showed that stress was differentially affecting the four groups (kinesic, high and low stress; vocalic, high and low stress). Males and females were affected in a similar manner by stress, with females being consistently more accurate decoders than males regardless of the amount of stress or channel used.
