The effects of competing reinforcement schedules on the acquisition of functional communication

The initial efficacy of functional communication training (FCT) was evaluated when problem behavior continued to produce intermittent reinforcement. Results for 2 of 3 participants showed that FCT was most effective when problem behavior was also exposed to extinction, response blocking, or both.     

An experimental analysis of negative reinforcement contingencies for adult-delivered reprimands

Seven adults participated in simulated teaching sessions with an experimenter who role played as a student with developmental disabilities. The experimenter engaged in problem behavior and either (a) terminated problem behavior contingent on participant reprimands (negative reinforcement) or (b) did not terminate problem behavior contingent on reprimands (extinction). Results suggested that reprimands were sensitive to negative reinforcement in the form of the immediate cessation of problem behavior. These preliminary findings support role play as a potentially viable laboratory model for analyzing behaviors of typical adults.     

Wie können Langzeittherapien mit kürzeren Behandlungen verglichen werden?

Long-term psychotherapy is not recommended in the current guidelines, which are based on the criteria of evidence-based medicine, as there is a lack of confirmation for long-term psychotherapy by efficacy studies. Using the example of psychoanalytic long-term psychotherapy this article describes six dilemmas which impede the realization of efficacy studies for long-term psychotherapy. Finally, basic elements of a study design are proposed, which are considered as being adequate to compare (psychoanalytic) long-term psychotherapy with shorter treatment forms in terms of outcome and cost-effectiveness. The anxiety and personality disorders (APD) study is briefly described as an example of a study realizing the proposed design.     

Models of competence in solving physics problems

We describe a set of two computer-implemented models that solve physics problems in ways characteristic of more and less competent human solvers. The main features accounting for different competences are differences in strategy for selecting physics principles, and differences in the degree of automation in the process of applying a single principle. The models provide a good account of the order in which principles are applied by human solvers working problems in kinematics and dynamics. They also are sufficiently flexible to allow easy extension to several related domains of physics problems.
