- 确定实施EMA的最佳策略,以最大限度地提高参与者参与度.
- 评估不同奖励结构和时间表长度在EMA完成后的有效性.
主要方法:
- 在健康@NUS队列研究中,在7个月内进行了3次EMA爆发.
- 实施了随机对照试验,以测试奖励结构和时间表长度 (7 vs. 14天).
- 利用ANOVA,协差分析和混合模型来分析响应率变化.
主要成果:
- 较长的EMA计划长度 (14天) 与较短的 (7天) 相比,显著增加了响应率.
- 响应率从第1次爆发大幅提高到第2次和第3次爆发,可能是由于短信提醒.

Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.

101
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
