The condom purchase task: A hypothetical demand method for evaluating sexual health decision-making

Behavioral economic theory has proved useful for understanding the influence of delay and probability on sexual health decision-making. Demand is another principle at the intersection of microeconomics and psychology that has helped advance research relevant to health behaviors. The purpose of the present study was to develop and test a demand measure related to sexual health decision-making and the influence of sexually transmitted infection (STI) risk. Participants (N = 438) recruited using Amazon Mechanical Turk completed a commodity purchase task assessing hypothetical condom demand. Condom demand was evaluated at varied prices for use with hypothetical sexual partners that varied in STI risk. Demand was characterized by prototypic decreases in consumption with increases in cost. Higher partner STI risk was associated with greater intentions for condom-protected sex at no cost and smaller decreases in condom demand with increases in cost. Price sensitivity was also related to individual difference factors relevant to sexual health (e.g., alcohol use severity, lower STI knowledge). This study supports the utility of a condom purchase task for indexing condom valuation and capturing individual difference and contextual risk factors relevant to STI transmission. Future studies may leverage this methodology as a means to study sexual health decision-making.     

On the robustness of the association between Honesty-Humility and dishonest behavior for varying incentives

Previous research consistently showed a negative link between Honesty-Humility (HH) and dishonest behavior. However, most prior research neglected the influence of situational factors and their potential interaction with HH. In two incentivized experiments (N = 322, N = 552), we thus tested whether the (subjective) utility of incentives moderates the HH-dishonesty link. Replicating prior evidence, HH showed a consistent negative link to dishonesty. However, the utility of incentives did not moderate this association, neither when manipulated through incentive size (BF₀₁ = 5.7) nor when manipulated through gain versus loss framing (BF₀₁ = 20.4). These results demonstrate the robustness of the HH-dishonesty link.     

Familiarity-Matching: An Ecologically Rational Heuristic for the Relationships-Comparison Task

Previous studies have shown that people often use heuristics in making inferences and that subjective memory experiences, such as recognition or familiarity of objects, can be valid cues for inferences. So far, many researchers have used the binary choice task in which two objects are presented as alternatives (e.g., “Which city has the larger population, city A or city B?”). However, objects can be presented not only as alternatives but also in a question (e.g., “Which country is city X in, country A or country B?”). In such a situation, people can make inferences based on the relationship between the object in the question and each object given as an alternative. In the present study, we call this type of task a “relationships-comparison task.” We modeled the three inference strategies that people could apply to solve it (familiarity-matching [FM; a new heuristic we propose in this study], familiarity heuristic [FH], and knowledge-based inference [KI]) to examine people's inference processes. Through Studies 1, 2, and 3, we found that (a) people tended to rely on heuristics, and that FM (inferences based on similarity in familiarity between objects) well explained participants' inference patterns; (b) FM could work as an ecologically rational strategy for the relationships–comparison task since it could effectively reflect environmental structures, and that the use of FM could be highly replicable and robust; and (c) people could sometimes use a decision strategy like FM, even in their daily lives (consumer behaviors). The nature of the relationships–comparison task and human cognitive processes is discussed.     

Characterising mobile phone calls while driving on limited-access roads based on SHRP 2 naturalistic driving data

Research has found that mobile phone call engagement while driving negatively affects driving performance. However, no studies exist characterising hand-held mobile phone calls while driving under naturalistic conditions that include aspects such as the duration of mobile phone subtasks and glance behaviour. Identifying the particularly distracting phases of hand-held telephoning and the nature of influencing factors are the basis for developing design recommendations (e.g. for an in-vehicle information system). Potential influencing factors on driving performance such as call type, mobile phone storage location, or any self-regulatory behaviour need to be taken into account. The present study aimed to draw a comprehensive picture of making hand-held mobile phone calls while driving on limited-access roads using SHRP 2 naturalistic driving data. Mobile phone phase duration, glance behaviour, call type, and mobile phone storage location were coded manually across 98 events. The results show that the handling phase of a mobile phone call (e.g. searching for contacts, dialling) was the most dangerous due to longer mean off- than on-road glances. Outgoing calls caused longer mean off-road glances than incoming; nevertheless, the 2 s critical threshold was not exceeded. A significant influence of mobile phone storage location on glance behaviour did not exist. Moreover, at least in free-flow driving conditions, drivers had enough spare capacity to conduct a mobile phone call without reducing vehicle speed. The results suggest that in low complexity traffic situations drivers can compensate for the increased driving task demand due to telephoning by making minor changes in glance behaviour.     

任务切换中的反应重复效应

在任务重复试次中反应的重复对反应有促进作用,而在任务切换试次中反应的重复对反应有阻碍作用,此现象即为反应重复效应（response repetition effects, RRE）。RRE普遍存在不同任务切换范式中,是一种抽象反应编码重复效应,受刺激效价和一致性、反应编码重复度和准备时间等因素影响。其理论解释主要有重构论、启动-抑制论、以及情境检索说。现有研究初步表明前额叶皮层是RRE的关键脑区,但RRE的认知神经机制及理论解释还有待进一步探讨。     

老年人汉语阅读中预测误差成本的产生机制

阅读的认知加工机制随年龄变老只发生了量变还是也产生了质变,是毕生发展研究领域的重要问题。要进行有效的语言处理,读者必须结合已有的经验知识和当前语境对即将出现的信息进行预测加工。因此,要解决上述问题就要回答老年人阅读中预测加工机制发生了怎样变化,即预测误差成本是如何产生的。研究拟采用眼动脑电同步记录技术,在自然阅读过程中实时获取语言处理的行为和神经指标,聚焦老年人预测误差成本的产生机制,主要从副中央凹视觉、工作记忆负荷及语言能力三方面解释预测误差成本产生的原因。研究成果对构建汉语阅读的毕生发展模型有重要意义。

本研究旨在通过联结学习任务和线索转换任务探讨自我关联刺激在任务转换和目标变化下的加工优势。结果发现：（1）相比于朋友和陌生人,自我更容易学习联结;（2）在线索转换任务中,所有关联刺激均未出现任务转换成本;（3）在目标变化条件下,自我关联刺激的目标结转效率最佳。结果表明自我关联刺激能够调节任务转换成本,并且在目标变化条件下能快速聚焦注意,表现出基于感知的特异性加工优势。     

序列学习是否是内隐学习？

序列学习是继人工语法之后内隐学习的另一研究范式。以往观点认为,在练习后,被试对规则刺激和随机刺激在反应时上出现差异,就表明被试是内隐学习,这种差异量就是内隐学习量。但现在很多学者对序列学习是否内隐这一问题提出了疑问;运用新方法（过程分离法,简称PDP）的研究发现,序列学习是否内隐同反应-刺激间隔（RSI）有关,当RSI = 0时,序列学习才是内隐的;根据RSI提出了神经网络模型。     

Behavioral Microanalysis of Helping Interactions Between Mothers and Adult Children with Mental Retardation

Although direct observation has provided much information regarding caregiver-care recipient interactions, our understanding of the applications of this technique remains incomplete. This study expands upon earlier observational work by examining adults with mental retardation (MR) and their family caregivers in the home setting. Specialized computer software was used to conduct real-time observation and recording of interactional styles of maternal caregivers of eight younger (M = 23 years old) and eight older (M = 49 years old) MR adults during two cognitive tasks: block design and card sorting. Differences in the amount and type of assistance provided by the caregiver were examined by coding the occurrence and duration of seven interactional behaviors. The results demonstrated that the caregivers of the younger adults used more positive statements and modeling/gestural prompts, whereas the caregivers of the older adults provided more physical assistance and performed more of the tasks themselves. More importantly, this project provided information regarding interactions between MR adults and their maternal caregivers and demonstrated the utility of computer-assisted data collection technology with a community-based, nondemented population.
