“…Despite some known limits (Eysenck, 1991;Paunonen & Jackson, 2000), over the last 50 years the Big Five model has become a standard in psychology and experiments using the Big Five have shown that personality traits influence many aspects of task-related individual behaviour. For example, the success of most interpersonal tasks depends on the personalities of the participants, and personality traits influence leadership ability (Hogan, Curphy, & Hogan, 1994), general job performance (Furnham, Jackson, & Miller, 1999), attitude toward machines (Sigurdsson, 1991), sales ability , teacher effectiveness (Rushton, Murray, & Erdle, 1987), and academic ability and motivation (Furnham & Mitchell, 1991;Komarraju & Karau, 2005). However, to date there has been little work on the automatic recognition of personality traits (Argamon, Dhawle, Koppel, & Pennebaker, 2005;Mairesse & Walker, 2006a, 2006bOberlander & Nowson, 2006).…”
