The psychological and physiological dynamics of a simple conversation

Two experiments examined several variables that influence first impressions between previously unacquainted, opposite gender participants. The first experiment investigated the relationship among measures of extroversion, cheerfulness, and attractiveness during a first encounter. Results showed that measures of attractiveness did not correlate with measures of extroversion and cheerfulness. The second experiment examined galvanic skin response (GSR) from male and female couples engaged in conversation. The results showed a significant direct relationship between the electrical conductivity of the skin for 10 pairs of participants who were engaged in a simple conversation.
