| Controlling the movement of an autonomous mobile robot requires the ability to pursue strategic goals in a highly reactive way. We describe a fuzzy controller for such a mobile robot that can take abstract goals into consideration. Through the use of fuzzy logic, reactive behavior (e.g., avoiding obstacles on the way) and goal-oriented behavior (e.g., trying to reach a given location) are smo...

Abstract This paper attempts to clarify the notion of goal-directedness, which is often misunderstood as being inconsistent with standard causal mechanisms. We first note that goal-directedness does not presuppose any mysterious forces, such intelligent design, vitalism, conscious intention or backward causation. then review at defining by means more operational characteristics: equifinality, p...

introduction: although many researches showed that there are several psychiatric comorbidities in people suffering from migraine headache, few studies investigated the relationship between deep psychopathological structures and headache variables. the purpose of the present study was to elucidate the relationship between early maladaptive schemas and three dimensions of headache impact, pain in...

In logic programming, almost no work has been done so far on proving that certain queries cannot succeed. Work in this direction could be useful for queries which seem to be non-terminating. Such queries are not exceptional, e.g. in planning problems. The paper develops some methods, based on abduction, goal-directedness, tabulation, and constraint techniques, for proving failure of queries for...

In this paper we outline a theory of the nature of self-directed agents. On our account what is distinctive about self-directed agents is that they are able to anticipate interaction processes and evaluate their performance. This allows self-directed agents to modify their behaviour context sensitively so as to improve the achievement of goals, and in certain instances construct new goals. We c...

To explicate M. Snyder's (1987) construct of self-monitoring (SM), a new Q-sort prototype is introduced. Analyses of Q-sorts by both observers and self demonstrated cross-method convergent validity for the revised 18-item Self-Monitoring Scale (SMS-R) and its Public Performing subscale; however, neither scale showed discriminant validity against measures of extraversion. The Other-Directedness ...
