Papua New Guinea has been defined as a collectivist (as opposed to individualist) culture (Triandis et al., 1986a). The aim of this study was to examine the effects of allocentricity on a standardised personality test, the Eysenck Personality Inventory, using a sample of Papua New Guinean university students. The responses of 256 subjects were factor analysed. The 22 factors extracted in the first-order analysis were reduced to eight factors in a higher-order analysis. These eight factors were only psychologically meaningful if interpreted within the context of a collectivist society. The implications for cross-cultural personality assessment are considered.

In this article I defend the following argument: 1) Empirical investigation can only be conducted with reference to statements that are empirically relevant; 2) Statements that refer to mental states cannot be defined so as to render them empirically relevant; 3) Therefore, there can be no empirical investigation of mental states.

Twenty male and five female undergraduates were assessed in a study designed to test for three dimensional pictorial perception in a Papua New Guinea sample. A version of Hudson's (1960) and Deregowski's (1968) test stimuli was used; the stimuli were slightly modified to make them culturally appropriate. The major result of the study was a finding of consistent sex differences in pictorial depth perception. Males tended to perceive three dimensionally while females tended to perceive two dimensionally.

Sport psychology has attracted the support of athletes and coaches in recent years but has yet to win the approval of mainstream academic psychology. This article considers arguments for and against the proposition that sport psychology is a legitimate subdiscipline within psychology.
