A simulation experiment was conducted to investigate the effects of task complexity and
individual experience on the reliability of operators of a hydrogen-making system in cognitive
vigilance tasks. 20 operators were selected as subjects from a large oil-plant, and they were
requested to perform four vigilance tasks with different levels of complexity in the experiment.
The results showed that there was a significant influence of task complexity on the reliability of
operators. The more complex the task, the lower the reliability. In a more complex vigilance task,
the individual experience also exerted a significant impact on the reliability of operators.

This paper first defined the construct of self-regulation of employees at work, based upon previous
literature and experimental research work and compiled a preliminary questionnaire to measure
self-regulation of employees at work. After pilot testing and a series of revisions, a questionnaire
on the self-regulation of employees at work was formed. Exploratory and confirmatory factor
analysis found that that self-regulation of employees at work was a multi-hierarchical and
multi-dimensional construct which had two hierarchies and nine dimensions. The new scale was
tested to be reliable and valid enough to be applicable to measure self-regulation of employees at
work.
5138.153 Psychological correlates of environmental sensitivity, Maaris Raudsepp, Tallinn
Pedagogical University, Estonia, EE
Environmental sensitivity (ES) characterizes person’s general pro-environmental orientation
(Chawla, 1998). Our aim was to analyze relations of ES with some psychological characteristics.
The data is based on a national representative survey (N=987). ES was operationalized through
various indicators (e.g. environmental concern, ecological behavior intention). Several
psychological measures (incl. short version of Schwartz’s value scale) were used. Individual
characteristics that differentiated more and less environmentally sensitive persons were value
preferences (altruistic, traditional, biocentric values), self-efficacy, optimism, generalized trust,
collectivism, collective and individual self-esteem, internal control belief. Neuroticism and
anomie had negative associations with ES. Theoretical implications of the results are discussed.
5138.154 Reducing sales of environmentally harmful products: Effects of uncertain subsidies on
price settings, Lars E. Olsson 1 , Manabu Akiyama 2 , Tommy Garling 1 , Mathias Gustafsson 1 ,

Increasing trends in production and consumption create adverse environmental impacts. Therefore,
policies targeting producer and consumer behaviour need to be developed and implemented. A
multi-trial duopoly price-setting game was devised to investigate effects on sales of governmental
subsidies compensating producers for any unsold quantities. Two experiments investigated effects
of uncertain non-fixed subsidy levels compared to known fixed subsidy levels. The results showed
that conditions with known and unknown subsidies led to higher prices and reduced sales
compared to conditions without subsidies. It is suggested that a subsidy system may be
implemented to reduce production of environmentally harmful products.
