Text‐message reminders plus incentives increase adherence to antidiabetic medication in adults with type 2 diabetes

Some adults with Type 2 diabetes mellitus have difficulty adhering to their oral medication regimens. The current study used a multiple baseline design with 3 adults with Type 2 diabetes. Medication taking was monitored remotely in real time via an electronic pill bottle. During the intervention, monetary incentives were delivered contingent on evidence of adherence to taking medication at specified times. Text‐message reminders were also sent if medication was not taken. Adherence increased for all participants. Future studies should separate the relative contributions of text‐message and incentive components of the intervention.     

Effects of time-based administration of abstinence reinforcement targeting opiate and cocaine use

Polydrug use is a common problem among patients in opioid-substitution treatment. Polydrug use has been reduced by administering abstinence-reinforcement contingencies in a sequence, such that a single drug is targeted until abstinence is achieved, and then an additional drug is targeted. The present study examined effects of administering abstinence-reinforcement contingencies sequentially based on time rather than on achieved abstinence. Participants accessed paid work (about $10/hr maximum) in the Therapeutic Workplace by providing urine samples 3 times per week. The urine samples were tested for opiates and cocaine. During an induction period, participants earned maximum pay independent of drug abstinence. Then, maximum pay depended upon urine samples that were negative for opiates. Two weeks later, maximum pay depended upon urine samples that were negative for both opiates and cocaine. Opiate and cocaine abstinence increased following administration of the respective contingencies. The time-based administration of abstinence reinforcement increased opiate and cocaine abstinence.     

The role of motivation and volition in economic decisions: Evidence from eye movements and pupillometry

Economic decisions usually involve high stakes, real consequences, and some degree of personal risk. This article explores the impact of motivational and volitional states on economic decision processes in an incentivized lottery choice task. We investigated the patterns of decision time, choice, information search, and pupil dilation dependent on an experimental manipulation of motivation and volition, that is, the deliberative and the implemental mindset. The results indicated that choice preferences in economic decisions were robust and remained unaffected by motivational and volitional states, but decision processes were notably impacted. Decision makers in a deliberative state of mind searched for information more extensively and made slower decisions than the baseline. The implemental mindset was associated with more attention paid to the probability attributes of the gambles relative to the deliberative mindset. Furthermore, we observed that gamble outcomes that entailed no win at all (i.e., zero outcomes) played an important role for information search. These outcomes were largely disregarded in terms of predecisional information search but elicited pupillary responses similar to very high outcome lotteries. These results inform the current debate about the zero effect in risky choice. We also discuss the potential of eye-tracking studies of risky choice to dissolve ambiguities concerning the contributions of effort and arousal to modulating pupillary response. Implications for theoretical advances in decision research are discussed.     

Age,Gender, and Level of Activity as Moderators of Personal Incentives to Physical Activity in Israel

The authors conducted an exploratory study with Israeli adults examining their personal incentives for physical activity (e.g., appearance, weight management). The participants formed a sample of 379 physically active Israelis, aged 20-89 years, divided into 3 age groups and 3 levels of activity. The authors found a similar profile for men and women for most incentives, with men scoring more highly than did women on only competition and fitness. Participants in the highest level of activity attributed greater importance to all incentives than did those in the other levels, and older adults attributed less importance to all incentives except for health benefits. The findings are relevant for planning activities intended to encourage adults to engage in more physical activity.     

Changing institutional incentives to foster sound scientific practices: One department

Replicable research and open science are of value to our field and to society at large, but most universities provide no incentives to adopt these practices. Instead, current incentive structures favor novel research, which has led to a situation in which few researchers take the time to do replications, share protocols, or share data. Obviously, several approaches to remedy this situation are possible. However, little progress can be made if becoming involved in such activities reduces a researcher’s chances of rank and status advancement and other rewards. I describe in this article the way my department has modified our incentive structure to tackle this problem, including how the changes influence my research as a developmental psychologist. Finally, I offer suggestions for faculty who wish to initiate similar changes in their institutions.     

The Power of Social Influence on Estimation Accuracy

Research shows that crowds can provide more accurate estimates of uncertain quantities than individuals (Surowiecki, 2004). But little is known about how to organize crowd members to maximize accuracy. When should crowd members work independently, and when should they work collaboratively? We examined the effects of social influence on estimation accuracy, consensus, and confidence. Participants first made independent estimates of uncertain quantities, such as the percentage of U.S. deaths due to heart attacks or the height of the tallest building. Then, in some conditions, they interacted with others online. After the discussion, they made second independent estimates. Social interaction improved accuracy. Despite well‐known problems with groups, such as herding and free riding, discussion resulted in more accurate estimates and greater consensus relative to independent estimates. We offer a simple model that describes the process by which group discussion improves the estimates of uncertain quantities. Copyright © 2014 John Wiley & Sons, Ltd.     

金钱刺激和决策者角色对个体道德决策的影响——基于过程分离范式

以大学生为被试,采用3（金钱刺激：无金钱刺激、金钱奖励、金钱惩罚）×2（决策者角色：决策者、旁观者）的被试间实验设计,利用过程分离范式分别计算被试道德决策中的功利主义倾向和道义论倾向,从而探讨金钱刺激和决策者角色对个体道德决策的影响。结果发现：（1）无论是决策者还是旁观者,金钱刺激都不会影响其道义论倾向;（2）决策者的道义论倾向大于旁观者;（3）只在有金钱奖励时决策者的功利主义倾向才大于旁观者。     

An analysis of a contingency program on designated drivers at a college bar

The present study evaluated the effects of prompts and incentives on designated drivers in a bar. We defined the dependent variable as the percentage of customers either functioning as or riding with a designated driver. We used an ABCA design to evaluate the effectiveness of prompts and incentives on the dependent variable. Results indicated that the intervention was successful at increasing the ratio of safe to unsafe passengers in a bar.     

A university-based incentive program to increase safety belt use: Toward cost-effective institutionalization

A cost-effective incentive program to increase safety belt use was implemented by the campus police of a large university. For each of the 3-week intervention periods during three consecutive academic quarters, the 22 campus police officers recorded the license plate numbers of vehicles with drivers wearing a shoulder belt. From these numbers, 10 raffle winners were drawn who received gift certificates donated by community merchants. Faculty and staff increased their belt usage markedly as a result of the "Seatbelt Sweepstakes," whereas students increased their belt use only slightly. A cost-effectiveness analysis indicated that the sweepstakes cost an average of $0.98 per each newly buckled driver. During each sweepstakes intervention, officers' belt usage increased significantly, but diminished to initial baseline levels after the final withdrawal of the program. Surveys of officers' opinions indicated that the police would accept the program demands as a regular task requirement. This result and the fact that program promotion and coordination were eventually taken over by two student organizations suggest that institutionalization of the "Seatbelt Sweepstakes" is feasible.
