training for the unemployed. Australian Journal of Psychology, 55(2), 104-113. Differential benefits of training 1 This study examined the connection between background variables (such as length of unemployment and number of previous training courses), contextual variables (perceptions of training climate), dispositional variables (positive affect and negative affect), and psychological outcomes for unemployed trainees who attended either a five week occupational skills training program (control group) or the same five week program with an additional two day intervention before the start of the program (treatment group). The trainees in both the treatment and control conditions were found to reduce their levels of psychological distress over the course of a five-week training program. Trainees in the treatment condition who started with the lowest levels of general self-efficacy and the highest levels of psychological distress showed the greatest improvements at time 2 (T2). The measures of length of unemployment, number of previous training courses, and the perceptions of the training climate (with

Donald Pate', Rebecca Brodie2 and Timothy D.

Man's presence i n Tasmania during the Pleistocene was recently demonstrated by a radiocarbon date of 18,550 + 600 BP (ANU-1361) from Cave Bay Cave, Hunter Island (Bowdler 1974a, b). Further excavation was carr ied out a t t h i s s i t e during January and February of t h i s year, and more radiocarbon da tes a r e t o hand. The archaeological sequence suggested before has been considerably c l a r i f i ed, and the new dates extend the an t iqu i ty of man i n the region by some 4,000 years. The s i t e is large and, of a s e r i e s of trenches, t ha t located nearest the centre of the cave (Trench V) most c lea r ly exhibits the s a l i en t features of i ts his tory. This cu t t ing w a s 2 m X 2 m i n area, and was excavated t o a depth of a l i t t l e over 2 m. Pleistocene layers were again recognised by non-island fauna1 remains, characterising the 'Hunter H i l l on Bass Plain ' period of lowered sea l eve l (Bowdler 1974a:7-8). The topmost

This paper uses a social psychological perspective to study the effectiveness of different media of communication and how they influence interactions in social groups and organizations. In particular, we are interested in the social richness of the media— how effectively they convey the personalities and intentions of their users. We studied CMC (email and chat) and voice telephony, and compared them with face-to-face interaction. Study 1 was a controlled laboratory study in which people got acquainted with a partner. Study 2 was a field survey in which employees reported on naturally occurring interactions at work that took place with people of varying levels of power (supervisor, peer, subordinate). The surprising result is that the telephone generally came out on top in both studies, suggesting that the telephone may provide the optimum blend of richness and presence for natural and satisfying interactions.
