Altering contingencies to facilitate compliance with traffic light systems

The effects of altering light pattern sequences on driver compliance at a busy, urban intersection were explored. The baseline light timing sequences resulted in only 46.8% of drivers stopping at the yellow or red lights. Using an A-B-C design, we altered light pattern sequences that increased the probability of drivers stopping at the signals to 88.8% and 98.8%. These findings indicate that traffic light contingencies have potent effects in influencing driver behaviors at busy intersections. Following completion of the study, the traffic engineer approved the permanence of the light timing pattern that increased traffic rule compliance. Accident data collected before and after the light timing changes indicated a reduction in automobile accidents.     

Making family therapy easier for the therapist: burnout prevention

Burnout prevention for family therapists can be enhanced by careful consideration of the degree of responsibility taken by the therapist contrasted with responsibility placed on the family. Attention to issues of expectations, role definition, sharing of feelings, and therapeutic ambition can ease the strain on the therapist.     

A systemic view of family therapy ethics

A critical review of the literature on family therapy ethics is used to develop the proposition that a more systemic analysis is needed, one that includes the levels of therapist and society as well as patient (family). These ideas are discussed through reexamining the issues of family secrets, therapist deceptiveness, and therapist advocacy of personal (feminist) values.
