“…The psychological distance between any two environmental or personality types is calculated according to the distance between similar and different personality types on the hexagon (see figure 1) (Gottfredson, & Richards, 1999). (Holland, 1997) When the literature on studies based on Holland"s vocational personality types are examined, there are studies testing the model in different cultures (Farth, Leong, & Law, 1998;Ferreira, & Hood, 1995), and making comparisons with different vocational interest models (Rounds, Davison, & Dawis, 1979;Tracey, & Rounds, 1993;Weinrach, 1996). In addition, there are also studies on the relationships between vocational personality types and variables such as sex (Anderson, Tracey, & Rounds, 1997;Ryan, Tracey, & Rounds, 1996) and personality traits (Larson, & Borgen, 2002;Mount et al, 2005;Tokar, & Swanson, 1995).…”
