Preference and reinforcer efficacy of high- and low-tech items: A comparison of item type and duration of access.

This study examined the interactions of stimulus type (high- vs. low-tech) and magnitude (duration of access) on preference and reinforcer efficacy. Two preference assessments were conducted to identify highly preferred high-tech and low-tech items for each participant. A subsequent assessment examined preference for those items when provided at 30-s and 600-s durations. We then evaluated reinforcer efficacy for those same items when provided for a range of durations using progressive-ratio schedules. Results suggested item type and access duration interacted to influence preference and reinforcer efficacy. Participants preferred high-tech items at longer durations of access and engaged in more responding when the high-tech item was provided for long durations, but these patterns were reversed for the low-tech item. In addition, participants engaged in less responding when the high-tech item was provided for short durations and when the low-tech item was provided for long durations.
