Change: Detection and Modification

Because human physiology is always changing, one of the challenges for those interested in biofeedback applications is how to establish techniques to determine if the biofeedback has altered the physiology. This paper explores some of the areas of concern and some solutions that have been reported.     

Change Detection: Training and Transfer

Observers often fail to notice even dramatic changes to their environment, a phenomenon known as change blindness. If training could enhance change detection performance in general, then it might help to remedy some real-world consequences of change blindness (e.g. failing to detect hazards while driving). We examined whether adaptive training on a simple change detection task could improve the ability to detect changes in untrained tasks for young and older adults. Consistent with an effective training procedure, both young and older adults were better able to detect changes to trained objects following training. However, neither group showed differential improvement on untrained change detection tasks when compared to active control groups. Change detection training led to improvements on the trained task but did not generalize to other change detection tasks.     

Patterns of Change: Forces and Motion

Patterns of Change: Forces and Motion is an integrated science lesson that uses the 5E lesson cycle to tie together science with language arts, mathematics, literature, technology, engineering and social studies in an engaging format applicable for young learners. This lesson has been uniquely designed for the purpose of providing elementary teachers with ideas for using hands-on minds-on activities to foster inquiry and discussion, while engaging their students to use technology as a learning tool. This lesson has been used on the elementary level to teach students about the forces that have an effect on motion.
