以往关于否定句理解的心理模拟过程是一步完成的还是两步完成的, 结果并不一致, 这与各个研究使用的实验材料类型有关。本研究以汉语确定性无界否定句为研究对象, 采用句-图匹配范式和2(句子类型:汉语确定性无界肯定句和汉语确定性无界否定句) × 2 (图片描绘事物状态与句子描述的事物状态的匹配类型:匹配与不匹配)被试内实验设计, 以对图片判断的反应时和正确率为指标, 探讨其理解的早期(250 ms)、中期(750 ms)和晚期(1500 ms)的心理模拟过程。研究结果表明:确定性无界否定句理解的心理模拟是分两步进行的, 首先模拟的是否定句的被否定状态, 随着加工时间的推进, 完成了对确定性无界否定句的第二步模拟即对实际状态的模拟。但是, 比其他类型否定句的模拟过程所用的时间要短, 即在阅读理解的中期就完成了心理模拟。 相似文献

传统认知理论认为我们只能间接知觉动允,而生态认知心理学则认为对动允的知觉是个体与环境信息直接共鸣的过程。生态认知心理学首先判定动允并不是存在于我们头脑中的认识,而是实际存在于个体-环境系统中的事实,对动允的直接知觉就是对动允的检测而非推测,是对动允信息的拾取而非对记忆内容的提取。这种直接知觉表现为身体的相关动作机制(动作神经元、肌肉组织等)与环境中动允信息的共鸣。进化与学习在共鸣的形成与发展中具有重要作用。 相似文献

This article criticizes what it calls perspectival thought experiments, which require subjects to mentally simulate a perspective before making judgments from within it. Examples include Judith Thomson's violinist analogy, Philippa Foot's trolley problem, and Bernard Williams's Jim case. The article argues that advances in the philosophical and psychological study of empathy suggest that the simulative capacities required by perspectival thought experiments are all but impossible. These thought experiments require agents to consciously simulate necessarily unconscious features of subjectivity. To complete these experiments subjects must deploy theory‐theoretical frameworks to predict what they think they would (or ought to) do. These outputs, however, systematically mislead subjects and are highly prone to error. They are of negligible probative value, and this bodes poorly for their continued use. The article ends with two suggestions. First, many thought experiments are not problematically perspectival. Second, it should be possible to carry out “in‐their‐shoes” perspectival thought experiments by off‐loading simulations onto virtual environments into which philosophers place subjects. 相似文献

Analogy and similarity are central phenomena in human cognition, involved in processes ranging from visual perception to conceptual change. To capture this centrality requires that a model of comparison must be able to integrate with other processes and handle the size and complexity of the representations required by the tasks being modeled. This paper describes extensions to Structure‐Mapping Engine (SME) since its inception in 1986 that have increased its scope of operation. We first review the basic SME algorithm, describe psychological evidence for SME as a process model, and summarize its role in simulating similarity‐based retrieval and generalization. Then we describe five techniques now incorporated into the SME that have enabled it to tackle large‐scale modeling tasks: (a) Greedy merging rapidly constructs one or more best interpretations of a match in polynomial time: O(n2log(n)); (b) Incremental operation enables mappings to be extended as new information is retrieved or derived about the base or target, to model situations where information in a task is updated over time; (c) Ubiquitous predicates model the varying degrees to which items may suggest alignment; (d) Structural evaluation of analogical inferences models aspects of plausibility judgments; (e) Match filters enable large‐scale task models to communicate constraints to SME to influence the mapping process. We illustrate via examples from published studies how these enable it to capture a broader range of psychological phenomena than before. 相似文献

Molecular dynamics simulations performed on tensile deformation of 〈1?1?0〉 Cu nanowire indicated that the nanowire undergoes double reorientation from 〈1?1?0〉 to 〈1?0?0〉 tensile axis followed by 〈1?0?0〉 to 〈1?1?2〉 tensile axis. It has been observed that the double reorientation results from the occurrence of twinning mode of deformation in both the original 〈1?1?0〉 and reoriented 〈1?0?0〉 Cu nanowires. The double reorientation in 〈1?1?0〉 Cu nanowire leads to tensile ductility as high as 260% thereby displaying superplastic like behaviour. The occurrence of double reorientation and the associated high tensile ductility have been restricted to low nanowire length below or equal to 7.15 nm with aspect ratio ≤1. Above this length (higher aspect ratio), the reorientation process has not been observed and the nanowire fails at significantly lower strains due to activation of multiple twin systems facilitating twin–twin interactions. 相似文献

In a task involving continuous action to achieve a goal, the sense of agency increases with an improvement in task performance that is induced by unnoticed computer assistance. This study investigated how explicit instruction about the existence of computer assistance affects the increase of sense of agency that accompanies performance improvement. Participants performed a continuous action task in which they controlled the direction of motion of a dot to a goal by pressing keys. When instructions indicated the absence of assistance, the sense of agency increased with performance improvement induced by computer assistance, replicating previous findings. Interestingly, this increase of sense of agency was also observed even when instructions indicated the presence of assistance. These results suggest that even when a plausible cause of performance improvement other than one’s own action exists, the improvement can be misattributed to one’s own control of action, resulting in an increased sense of agency. 相似文献

Computer simulation through an error-statistical lens 总被引:1,自引:1,他引:0
Wendy S. Parker 《Synthese》2008,163(3):371-384
After showing how Deborah Mayo’s error-statistical philosophy of science might be applied to address important questions about
the evidential status of computer simulation results, I argue that an error-statistical perspective offers an interesting
new way of thinking about computer simulation models and has the potential to significantly improve the practice of simulation
model evaluation. Though intended primarily as a contribution to the epistemology of simulation, the analysis also serves
to fill in details of Mayo’s epistemology of experiment. 相似文献

How extraverted is honey.bunny77@hotmail.de? Inferring personality from e-mail addresses 总被引:1,自引:0,他引:1

Computer mediated communication (CMC) plays a rapidly growing role in our social lives. Within this domain, e-mail addresses represent the thinnest slice of information that people receive from one another. Using 599 e-mail addresses of young adults, their self-reported personality scores and the personality judgments of 100 independent observers, it was shown that personality impressions based solely on e-mail addresses were consensually shared by observers. Moreover, these impressions contained some degree of validity. This was true for neuroticism, openness, agreeableness, conscientiousness, and narcissism but not for extraversion. Level of accuracy was explained using lens model analyses: Lay observers made broad use of perceivable e-mail address features in their personality judgments, features were slightly valid and observers were sensitive to subtle differences in validity between cues. Altogether, even the thinnest slice of CMC—the mere e-mail address—contains valid information about the personality of its owner. 相似文献
