The surprisingly low motivational power of future rewards: Comparing conventional money-based measures of discounting with motivation-based measures

Temporal discount rates are often poor predictors of behaviors that we expect will be motivated by the future. The current research suggests this may be because conventional discounting measures are poor measures of the motivational value of future rewards. In six studies, I develop motivation-based measures of the present value (PV) of future rewards and compare the PVs obtained with those obtained using conventional money-based discounting measures. Conventional money-based PVs consistently overestimate motivation-based PVs and are discriminable from them. I explore explanations for this mismatch, including timing of effort exertion (Study 2) and loss aversion (Study 3), both features of the motivation-based measures. In Study 5, I use self-reports of valuation strategies and a time pressure manipulation to demonstrate that participants use different valuation strategies in the conventional money-based and the motivation-based measures that, in part, determine the difference in PVs obtained and the relatively low correspondence between them.     

Local communities responding to ecological challenges—A psycho‐social approach to the Natura 2000 Network

The institutionalization of biodiversity conservation through legal instruments has led to mixed reactions at both the individual and community levels, with conflict and resistance co‐existing with support. The overall purpose of this paper is to describe how rural communities living in areas included in the Natura 2000 Network of protected sites, where local practices of land use are regulated by new legal directives, receive biodiversity conservation goals. Previous studies suggest that this reception is strongly shaped by place identification, but their contradictory results demand further clarification. This study examines the role of psycho‐social variables identified by previous studies as potentially relevant moderators of identification: (a) Vested interest in natural resources, (b) evaluation of the designation process of protected areas and (c) institutional trust. It further extends previous research by analysing the support given to contextually relevant ecological practices. Results reveal a positive link between place identification and attitudes in the high vested interest condition and show that support for conservation practices is better predicted in the high vested interest and low trust conditions. The discussion focuses on the relevance of analysing contextually relevant psycho‐social moderators when attempting to understand how local communities' relation with biodiversity conservation is affected by legislative innovation.

Prior sensitivity in theory testing: An apologia for the Bayes factor

A commonly voiced concern with the Bayes factor is that, unlike many other Bayesian and non-Bayesian quantitative measures of model evaluation, it is highly sensitive to the parameter prior. This paper argues that, when dealing with psychological models that are quantitatively instantiated theories, being sensitive to the prior is an attractive feature of a model evaluation measure. This assertion follows from the observation that in psychological models parameters are not completely unknown, but correspond to psychological variables about which theory often exists. This theory can be formally captured in the prior range and prior distribution of the parameters, indicating which parameter values are allowed, likely, unlikely and forbidden. Because the prior is a vehicle for expressing psychological theory, it should, like the model equation, be considered as an integral part of the model. It is argued that the combined practice of building models using informative priors, and evaluating models using prior sensitive measures advances knowledge.     

The rise of chatbots: The effect of using chatbot agents on consumers' responses to request rejection

This research investigates consumers’ perceptions and evaluations of robot service agents compared with human service agents when service requests are rejected. Six studies were conducted. The results show that when consumers receive a rejection of their service request, they evaluate the service less negatively if the service is handled by a chatbot agent versus a human agent. The reason is that consumers have lower expectations that robots will be able to provide flexible services to them. Consequently, their dissatisfaction with the request rejection is lower when the service is handled by robots. However, the aforementioned effect is not observed (1) when consumers have not experienced the service yet, (2) when their service request has been accepted, or (3) when the service agent conveys emotions to apologize for request rejection.

质性研究中的资料饱和及其判定

在质性研究中,资料饱和通常被用以评估研究资料的充足性。但在研究实践中,资料饱和却存在概念模糊及操作性问题。作为某项质性研究所抽取的样本量已满足研究需要的标志,按照在研究过程中判定时点的先后顺序,资料饱和可划分为数据饱和、编码或主题饱和、意义饱和及理论饱和4种主要形式。4种形式的资料饱和各有其特定的内涵、评估方式和判定标准。研究认为,达到资料饱和的样本量标准不应统一设定,其检验需嵌入具体的研究过程;资料饱和存在逻辑上的不确定性,适度追加抽样有助于进一步确认;资料饱和作为考察研究质量的一项重要指标,并不适用于所有质性研究。     

The effect of the validity of co‐occurrence on automatic and deliberate evaluations

Co‐occurrence of an object and affective stimuli does not always mean that the object and the stimuli are the same valence (e.g., false accusations that Richard is a crook). Contemporary theory posits that information about the (in)validity of co‐occurrence has stronger influence on deliberate than automatic evaluation. However, available evidence supports that hypothesis only when the (in)validity information is delayed. Further, the existing evidence is open to alternative methodological accounts. In six high‐powered experiments (total N = 1750), we modified previous procedures to minimize alternative explanations and examine whether delayed (in)validity information has a discrepant effect on automatic versus deliberate evaluation. Casting doubt on the generality of the hypothesis, we found more sensitivity of deliberate than automatic evaluation to delayed validity information only when automatic evaluation was measured with the Implicit Association Test and not with the evaluative priming task or the affective misattribution procedure.     

利他惩罚中的结果评价—— ERP研究

利他惩罚是指个体为惩罚违反社会规范的人, 自愿支付成本。前人研究发现利他惩罚行为激活了背侧纹状体等与奖赏有关的脑区, 因此可以认为利他惩罚的结果是一种相当于金钱奖赏的正性结果, 不惩罚结果则是一种负性结果。本研究利用事件相关电位技术考察了被试在多次信任博弈游戏中观察“利他惩罚结果”和“不惩罚结果”的脑电成分, 结果发现被试产生了明显的反馈相关负波(feedback related negativity, FRN), 且负性程度更大的“不惩罚”结果其FRN波幅大于负性程度更小的“惩罚”结果。因为FRN是对负性反馈结果敏感的一个脑电成分。可见个体并非把利他惩罚结果知觉为一种正性结果, 因此FRN反映了对社会结果的情绪动机意义的评价。
