Mental time travel ability and the Mental Reinstatement of Context for crime witnesses

Mental time travel ability marks how well the phenomenological aspects of events are mentally re-experienced during recall. The Cognitive Interview (CI) elicits eyewitness information. One of its techniques, Mental Reinstatement of Context (MRC), asks eyewitnesses to reinstate the incident’s context mentally before recall. Fifty-six participants watched a simulated crime video. Self-report measures were then taken to estimate general mental time travel ability. Participants were questioned subsequently about the video. Eyewitness performance under MRC was compared with the CI’s Report Everything (RE) technique, wherein eyewitnesses recall everything they can but with no invitation to mentally reinstate the context. There was no effect of interview condition on accuracy of recall; however, general mental time travel ability was positively associated with the amount of correct and incorrect information produced under MRC, but not RE, conditions. This is the first empirical demonstration that MRC instructions engage the mental time travel capacities they purport to.

快速启动范式（Sereno & Rayner, 1992）是一种基于呈现随眼动变化技术而设计的眼动范式,主要用于研究中央凹视野内字词识别的瞬时启动,通过精确控制启动条件和启动时窗,以考察词汇通达过程中词汇水平（如,词频、词长等）、亚词汇水平（如,语音、语义、字形等）信息的加工时序。本文从基本原理、设计基础、应用领域、注意事项等方面对快速启动范式进行了较为深入的解读和介绍,并结合已有的研究成果,指出了该范式在汉语阅读中的应用价值。     

Facilitation of return in voluntary orienting to visual attributes1

Abstract: The present study examined the effects of voluntary and automatic orienting after a relatively long interval in an attentional cueing paradigm. Facilitation of return was observed after the voluntary orienting to a designated color (Experiment 1) and motion direction (Experiment 2), whereas inhibition of return was observed after the automatic orienting to an abrupt stimulus onset (Experiment 1). These results suggest that the voluntary orienting to a visual attribute modulates subsequent processes differently from the automatic orienting to an abrupt onset. In the voluntary orienting to visual attributes, it would be advantageous to return attention to the previously attended location, which is a potential source of information.     

A generalization of Piéron's law to include background intensity and latency distribution

Piéron's law, which formulates the effect of the signal intensity i on the mean or the median reaction time (MRT) as a power function, MRT=R+i^-βC, in which R, β and C are positive parameters, is of much interest in the simple reaction time literature. In particular, consistent estimates of β are obtained. However, this law offers no information regarding the effect of the signal intensity on other aspects of the reaction time distribution. In addition, the background intensity, which also has some impact on the detectability of the signal, is not considered in Piéron's law. In this paper, we generalize Piéron's law based on the above comments. That is, we assume that both β and C are functions of the background intensity and of the percentile rank. We then investigate from a theoretical viewpoint some possible functional forms of β and C, with a special emphasis on the dependency of β on the background intensity. It is shown that the so-called “Fechner-Thurstone-type representation” forces β and C to be “separable.” If we further assume a near-miss to Weber's law-type representation, then the functional form of β can be determined.

Age-related changes in children's executive functions and strategy selection: A study in computational estimation

Third, fifth, and seventh graders selected the best strategy (rounding up or rounding down) for estimating answers to two-digit addition problems. Executive function measures were collected for each individual. Data showed that (a) children's skill at both strategy selection and execution improved with age and (b) increased efficiency in executive functions contributed significantly to age-related improvement in children's strategy selection skill. These findings have implications for understanding of age-related differences in computational estimation, strategy selection processes, and mechanisms of strategic development in children.     

Computational exploration of metaphor comprehension processes using a semantic space model

Recent metaphor research has revealed that metaphor comprehension involves both categorization and comparison processes. This finding has triggered the following central question: Which property determines the choice between these two processes for metaphor comprehension? Three competing views have been proposed to answer this question: the conventionality view ( Bowdle & Gentner, 2005 ), aptness view ( Glucksberg & Haught, 2006b ), and interpretive diversity view ( Utsumi, 2007 ); these views, respectively, argue that vehicle conventionality, metaphor aptness, and interpretive diversity determine the choice between the categorization and comparison processes. This article attempts to answer the question regarding which views are plausible by using cognitive modeling and computer simulation based on a semantic space model. In the simulation experiment, categorization and comparison processes are modeled in a semantic space constructed by latent semantic analysis. These two models receive word vectors for the constituent words of a metaphor and compute a vector for the metaphorical meaning. The resulting vectors can be evaluated according to the degree to which they mimic the human interpretation of the same metaphor; the maximum likelihood estimation determines which of the two models better explains the human interpretation. The result of the model selection is then predicted by three metaphor properties (i.e., vehicle conventionality, aptness, and interpretive diversity) to test the three views. The simulation experiment for Japanese metaphors demonstrates that both interpretive diversity and vehicle conventionality affect the choice between the two processes. On the other hand, it is found that metaphor aptness does not affect this choice. This result can be treated as computational evidence supporting the interpretive diversity and conventionality views.
