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.
本研究考察了刺激类型（高科技与低科技）和强度（接触时长）对偏好及强化物效能的交互作用。进行了两项偏好评估，以确定每位参与者高度偏好的高科技和低科技物品。随后的一项评估考察了在30秒和600秒时长提供这些物品时的偏好情况。然后，我们使用累进比率程序，在一系列时长下提供相同物品时评估强化物效能。结果表明，物品类型和接触时长相互作用，影响偏好和强化物效能。参与者在较长接触时长时更喜欢高科技物品，当长时间提供高科技物品时会做出更多反应，但对于低科技物品，这些模式则相反。此外，当短时间提供高科技物品以及长时间提供低科技物品时，参与者的反应较少。
