Prior research has revealed that having choice over treatments can improve their efficacy. However, it is currently unknown if the benefits of treatment choice hold for complex decisions and different cultures. The effects of differing numbers of treatment options were explored across two cultural contexts: United States and Japan. Participants were exposed to an uncomfortable stimulus and provided with up to 15 placebo treatment options they believed would reduce discomfort. There was a significant interaction such that participants from Japan benefited most from fewer treatment options (2 and 5) compared with more treatment options (10 and 15). Participants from the United States, however, showed either no change in discomfort or less discomfort as the number of choices increased. Additionally, participants from Japan reported less satisfaction with the decision process when they had more treatment options to choose from whereas U.S. participants reported similar, if not slightly higher, satisfaction with more treatment options. Further, a second study indicated that a positive experience with the decision process mediated the relationship between choice complexity and treatment efficacy for Japanese participants. These data demonstrate the importance of culture and choice complexity when discussing treatment choice and resulting outcomes in the medical context. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Humans and other animals discount the value of rewards over time. One explanation for this is that delayed rewards may be less certain than immediate rewards, what has been referred to as the implicit risk hypothesis. Although this explanation is widely accepted, little research has directly assessed the validity of the implicit risk hypothesis. In the current study, we present two experiments in which participants made decisions about rewards involving both delay and uncertainty. By manipulating the order in which information was presented, we were able to investigate whether delay information facilitates beliefs about uncertainty and vice versa. It was found that participants were more likely to prefer larger, delayed rewards when information about delay was presented before information about uncertainty than when the information was presented in the opposite order. Additionally, we describe a process model that implements the implicit risk hypothesis and show that it is consistent with the observed patterns of data. These results support the implicit risk hypothesis and suggest that information about delay facilitates the processing of information about uncertainty. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Global identification has become a popular construct in recent psychological debate as it relates to harmonious intergroup relations and a caring for all humanity. Based on social identity theorizing, the current research tests whether global identification can also predict consumer choices, at the expense of lower personal benefit. Importantly, we assumed that concerns about global injustice represent a crucial component of that relation. We predicted that participants who identified strongly with all humanity would rather choose a Fairtrade product alternative over a conventional one, compared with low identifiers. In addition, we assumed that this effect be mediated by perceived global injustice. Both predictions were confirmed in a consumer choice study (N = 68). Overall, global identification and globally relevant consumer behavior seem meaningfully interconnected, and we discuss these findings with regard to recent theoretical developments in Fairtrade consumption research. 相似文献

We examined whether the combination of two factors that have consistently been found to enhance motor learning – an external focus (EF) of attention and autonomy support (AS) – would produce additive benefits. Participants practiced throwing with their non-dominant arm. In a 2 × 2 design, they were or were not asked to focus externally (i.e., on the target), and were or were not given a choice (autonomy support). The latter involved choosing 2 5-trials blocks during practice on which they used their dominant arm. All four groups – EF/AS, EF, AS, and C (control) – completed a practice phase consisting of 60 trials. The distance to the target (bull’s eye) was 7.5 m. One day later, participants performed retention (same target distance) and transfer tests (8.5 m). Both external focus instructions and autonomy support enhanced retention and transfer performance. Importantly, the combination of these factors resulted in additive learning advantages. The EF/AS group showed the greatest throwing accuracy, and the EF and AS groups outperformed the C group. In addition, self-efficacy measured after practice and before retention and transfer was increased by both factors. Thus, promoting an external focus of attention and supporting learners’ need for autonomy seem to independently influence learning. 相似文献

采用中性抽象名词探测在再认测试和自由回忆条件下的自我选择权效应。实验一采用选择与迫选的方式考察抽象名词在再认条件下的自我选择权效应;实验二进一步验证被试在我选择和他选择条件下对抽象名词的自由回忆的差异。结果表明:无论在再认测试还是自由回忆测试,被试对自我选择的抽象名词的记忆数量都显著高于迫选和他人选择条件下的抽象名词记忆的数量,中性抽象名词表现出了自我选择权效应,拓展了前人使用假词时在自由回忆条件下未表现出自我选择权效应。因此,自我选择权效应在自由回忆条件下可以存在于抽象名词的水平上。 相似文献

The impact of food insecurity on child development in the general U.S. population is well‐established, yet little is known about the harm of food neglect relative to other types of maltreatment. Due to the harmful physiological impact of inadequate nutrients and the social impact of food‐related stress, it was hypothesized that food neglect would be more likely to impair infant cognitive and language development than physical abuse, sexual abuse, and other forms of neglect. Families of infants (N = 1,951) investigated by Child Protective Services were studied using the second cohort of the National Survey of Child and Adolescent Well‐Being (NSCAW II; NSCAW Research Group, 2002). Results from multivariable logistic regression models that controlled for likely confounding variables showed that the odds of impairment in cognition and language were significantly greater when food neglect was the most serious form of maltreatment. Considering that both food insecurity and child neglect are associated with poverty and parental mental health problems, it will be important for child welfare and mental health professionals to work collaboratively to better the health of these vulnerable children. 相似文献
