Individual differences in everyday retrospective memory failures

The present study examined individual differences in everyday retrospective memory failures. Undergraduate students completed various cognitive ability measures in the laboratory and recorded everyday retrospective memory failures in a diary over the course of a week. The majority of memory failures were forgetting information pertaining to exams and homework, forgetting names, and forgetting login and ID information. Using latent variable techniques the results also suggested that individual differences in working memory capacity and retrospective memory were related to some but not all everyday memory failures. Furthermore, everyday memory failures predicted SAT scores and partially accounted for the relation between cognitive abilities and SAT scores. These results provide important evidence for individual differences in everyday retrospective memory failures as well as important evidence for the ecological validity of laboratory measures of working memory capacity and retrospective memory.     

注意控制和短时存储对音位流畅性和语义流畅性的影响

工作记忆的中央执行系统具有注意控制和短时存储的功能。采用双任务范式,探讨了中央执行系统的注意控制和短时存储对言语流畅性的影响。实验1考察了中央执行系统的转换和抑制功能对音位流畅性和语义言语流畅性的影响。结果表明,中央执行系统的转换和抑制功能对两种言语流畅性的影响相当。实验2考察了中央执行系统的注意控制资源和短时存储资源对两种言语流畅性的影响。结果表明,语义流畅性更依赖于短时存储资源,音位流畅性更依赖于注意控制资源。研究还发现,被试完成语义流畅性任务的策略更易受概念系统的特性影响,完成音位流畅性任务的策略更易受语言的特点影响。在实验研究的基础上,作者提出了工作记忆影响言语流畅性的理论模型     

不同学习方式下归类不确定时的特征推理

采用学习-迁移模式, 探讨了同时学习和继时学习两种方式下归类不确定时的特征推理。共包括2个实验, 其中实验1探讨了固定学习轮次的情况, 实验2探讨了固定学习正确率的情况。实验结果表明：同时呈现类别要素的同时学习方式下, 被试习得序列式的单类别表征(原型表征), 在归类不确定时的特征推理中按照“单类的Bayesian规则”进行特征推理, 即P(j\F) =P(k\F)·P(j\k); 相继呈现类别要素的继时学习方式下, 被试习得并列式的多类别表征, 在归类不确定时的特征推理中按照“理性模型”进行推理, 即 P(j\F) =Σk P(k\F)·P(j\k)。

Examining normative pressure in the theory of planned behaviour: Impact of gender and passengers on intentions to break the speed limit

This research examined the impact of passenger-type on young people’s responses to a driving scenario about speeding. In the scenarios, the presence, and gender of the passenger were systematically varied. A total of 162 respondents (83 females, 79 males) completed questionnaires containing measures from the Theory of Planned Behaviour (TPB) and additional variables after reading each of two scenarios. The TPB provided good predictions of intention to speed (45% explained variance) with all TPB variables plus moral norms and past behaviour significant. Males compared to females reported significantly greater normative pressure to speed, less control over not speeding, and less moral norms not to speed. Normative pressure was a stronger predictor of intentions for men compared to women when driving alone. Normative pressure was a stronger predictor of intentions when the passenger was male.     

Mitigating road impacts on animals through learning principles

Roads are a nearly ubiquitous feature of the developed world, but their presence does not come without consequences. Many mammals, birds, reptiles, and amphibians suffer high rates of mortality through collision with motor vehicles, while other species treat roads as barriers that reduce gene flow between populations. Road effects extend beyond the pavement, where traffic noise is altering communities of songbirds, insects, and some mammals. Traditional methods of mitigation along roads include the creation of quieter pavement and tires and the construction of physical barriers to reduce sound transmission and movement. While effective, these forms of mitigation are costly and time-consuming. One alternative is the use of learning principles to create or extinguish aversive behaviors in animals living near roads. Classical and operant conditioning are well-documented techniques for altering behavior in response to novel cues and signals. Behavioral ecologists have used conditioning techniques to mitigate human–wildlife conflict challenges, alter predator–prey interactions, and facilitate reintroduction efforts. Yet, these principles have rarely been applied in the context of roads. We suggest that the field of road ecology is ripe with opportunity for experimentation with learning principles. We present tangible ways that learning techniques could be utilized to mitigate negative roadside behaviors, address the importance of evaluating fitness within these contexts, and evaluate the longevity of learned behaviors. This review serves as an invitation for empirical studies that test the effectiveness of learning paradigms as a mitigation tool in the context of roads.     

“动作-评价”效应:动作与认知的交互作用

"动作-评价"效应是具身认知理论的一个重要的支持性证据。早期研究表明,人们倾向于对积极刺激做"拉"反应而对消极刺激做"推"反应,进而在效价评定过程中表现出一种"动作-评价"效应。而随后一系列研究发现该效应的表现模式并非固定,并且该效应的发生不仅限于"推拉"动作。相应的,研究者也对这些现象做出了多种观点解释。进一步研究需继续深入探索"动作-评价"效应的本质及该效应的局限范围,以统合各种观点。
