Once basic needs are satisfied, the relation between income and subjective well-being is small, and materialism leads to diminished well-being. This study attempts to determine: (1) whether experiential purchases, as opposed to materialistic purchases, are likely to increase well-being and (2) whether these increases are likely to be due to increased satisfaction of psychological needs and/or decreased social comparison. Participants indicated that experiential purchases represented money better spent, brought more happiness to themselves, and brought more happiness to others. Path models demonstrated that experiential purchases had an indirect effect on one's well-being through two independent paths: (1) increased relatedness, which then led to increased vitality, and (2) decreased social comparison. Discussion focuses on why vitality and social comparison affect well-being.

A technique is described for studying exploratory as well as stereotyped behaviour in rats using an automated hole-board. Both visual and automated recordings can be employed using the technique. Hole dipping is monitored automatically using an infra-red detector system. Repetitive patterns of hole-dipping are used as parameters of stereotyped behaviour while the more random patterns of hole-dipping are used as parameters of exploration. There was a high significant correlation between the records of hole-dipping behaviour as recorded visually and automatically. There was also a high significant correlation between the measures of repetitiveness/randomness of hole-dipping behaviour from automatic and visual recordings. The pattern and levels of hole-dipping conformed with expectations both as regards changes with time and with increasing doses of dl-amphetamine.

Exploratory and stereotyped behaviour of Male Wistar rats was studied on a hole-board. The two forms of behaviour were differentiated according to the pattern of hole-dipping activity. Increasing doses of dl-amphetamine stimulated both forms of behaviour with stereotyped behaviour becoming predominant particularly at the higher dose levels. At the highest dose of amphetamine used (16 mg/kg) a gradual transition from exploratory to stereotyped behaviour was observed with time. As the drug wore off this transition was reversed. Haloperitol at a dosage of 0.1 and 0.05 mg/kg blocked the response to a high dose of amphetamine whereas a lower dose (0.02 mg/kg) blocked the stereotyped response to amphetamine while some exploratory behaviour still took place. Apomorphine inhibited hole-dipping but at lower doses another form of exploratory behaviour was induced, this behaviour becoming stereotyped as the dose was increased. It is concluded that there is a close relationship between exploratory and stereotyped behaviours. Monoamine systems appear to play a significant role in the regulation of both forms of behaviour.
