We assessed the effects of posted feedback and warning ticket programs on speeding and accidents in two cities. In Experiment 1, speeding feedback signs were effective even when 10 were used in Dartmouth, Nova Scotia, and reductions in speeding were associated with reductions in accidents. The effectiveness of the signs was correlated with the number of intersections and residences within 0.5 km beyond them, and the signs had no effect on untreated streets. In Experiment 2, posted feedback and a warning program reduced speeding and accidents on 14 streets in Haifa, Israel. 相似文献

Dual-task methodology was used to assess a multiple-resources account of information processing in which each cerebral hemisphere is assumed to have access to its own finite amount of attentional resources. A visually presented verbal memory task was paired with an auditory tone memory task, and subjects were paid to emphasize one task more than the other. When subjects were trying to remember tones presented to the right ear, they could trade performance between tasks as a function of the emphasis condition, whereas on left-ear trials they could not. In addition, a control session indicated that stimuli presented to the unattended ear demanded processing resources, even when it was to the detriment of performance. The data support the assumption of independence between the hemispheres' resource supplies. 相似文献

In the present study, a tailoring methodology was employed to investigate the detection of early interactional change in the course of family therapy and the possible prognostic value of such change for therapy outcome. The predicted relationship received partial support and suggested a model of change in families, with early interactional change as a mediating factor. 相似文献
