Social behavior, as compared to the egoistic behavior, is known to be more beneficial to groups of subjects and even to individual members of a group. For this reason, social norms naturally emerge as a product of evolution in human and animal populations. The benefit of the social behavior makes it also an interesting subject in the field of artificial agents. Social interactions implemented i...

In universal personal telecommunication (UPT) environments, UPT networks retain information related to incall/outcall registration in UPT user service profiles in order to provide incoming UPT calls for UPT users in any location who have registered at a terminal. As UPT networks support incall registration, terminal users can be different from terminal owners, and several UPT users can register...

researchers demonstrate that individuals in different levels of physical activity have different motivations for sport activity. this study was designed to examine how motivations can discriminate three physical activity levels (inactive, active, sustained maintainers) according to self-determination theory. 159 zanjan university staff (mean age: 33 years old) completed exercise motivation inve...

Narcissistic perfectionism is frequently described in theory, but there are no empirically tested models of this construct. Our study tested a model of narcissistic perfectionism, and differentiated this construct from self-critical perfectionism. Data from two samples of undergraduates, including a 28-day daily diary study, were used to test the factorial validity of narcissistic perfectionism...

Accurate simulation models of social networks enable over time prediction, statistical testing of hypothesis about social groups, and enables researchers to develop more informed hypotheses for human experimentation, by evaluating them and reasoning about them using simulation. Several methods for simulating social network behavior are compared. The multi-agent simulation Construct is shown to ...

This article presents findings from five repertory grid interviews conducted in early 2001 to identify attributes of information as an asset. Repertory grid is a technique developed by George Kelly based on his theory of personal constructs. Personal construct theory (PCT) assumes that individuals are their own ‘personal scientists’ who mentally represent the world around them. The method was u...

Work is currently in progress on the following projects: What do experts/novices know about programming. T1 The objective here is to develop a plan-based theory of programming knowledge and to test it empirically with novice and expert programmers. We are also using this theory to study the bugs and misconceptions of novice programmers. Cognitively appropriate programming language constructs.’ ...
