    It is known that reflective thinking, particularly measured by the Cognitive Reflection Test, predicts a broader range of intuitive-analytic responses. However, recent work by Gervais et al. (2018) demonstrated that the link between CRT and religious disbelief was not evident in less religious society and suggested that CRT measures a tendency to question prevailing cultural norms. In this study, we investigated the effect of CRT on various tasks where normative response was assumed to be either common or different across cultures. Using Bayesian multilevel analysis, we found that consistent negative relationship between CRT and intuitive response across tasks and no cultural difference in the effect of CRT on syllogistic reasoning. However, we found that the link between CRT and denominator neglect bias was different across cultures; on the other hand, it was also evident that the effect on paranormal belief was not different.

    The purpose of this study was to investigate the time-course of morphological processing using event-related potentials(ERPs) in Sino- Korean prefix derivational word. We conducted a lexical priming decision task comparing time-course of a morphological, a semantic, and an orthographic condition. The behavioral data showed significant positivity priming effect in a morphological and semantic priming condition. The ERP data revealed only significant morphological and semantic priming at N250(200-300ms). Also, a reduction of the N400(300-500ms) in the semantic condition. Also, increase of negativity amplitude of semantic priming in P600(550-750ms) observed. This result shows that the morpheme is mainly influenced by the semantic factor but not the orthographic factor from the onset to offset of the recognition of Sino-Korean prefix derivational word.

    The directionality of verbal probabilities (verbal terms conveying probabilistic information) is supposed to affect decision making independent from the subjective probability interpretations. At the same time, it may evoke emotions, especially intuitive feelings, which have an effect on people’s decisions. However, little is known about the relation between verbal probabilities and emotions, let alone the mechanisms under their influence on decision making. The present study investigated the implicit association between verbal probabilities (positive or negative) and emotional valance (good or bad) using the Implicit Associated Test (IAT). The results show that positive expressions were more associated with positive emotional valance than negative expressions were, suggesting that the effect of directionality of verbal probabilities may be mediated by emotional valance.

    Previous studies have shown that people can make adaptive inferences based on memory-based simple heuristics such as recognition, fluency, or familiarity heuristic. In the present study, we discussed the adaptive nature of memory-based simple heuristics in a group decision making setting. In particular, we examined how the diversity of memory affected group decision making. We predicted that, when the group members’ memories were diverse, group decision making would become more accurate. To examine this prediction, we conducted a behavioral experiment and computer simulations, and our results generally supported the prediction. These results suggested that diversity of memory in group members can boost performance of group decision making.

    Yama et al. (2017) reported hindsight bias in perceptions of the muddiness and the predictability of a flash flood in a river, as part of the author’s expert testimony in a court trial. The defendants had taken children to the river to play when a flash flood occurred that led to the drowning of one child. The core question was if the defendants could have predicted the flood using a visible cue: the muddiness of the river. Participants who knew the outcome of flash flood estimated the river muddier. The instruction on causality between the muddiness and the flush flood was manipulated in this current study. Participants were grouped into two conditions: the control condition and the outcome condition. The hindsight bias was confirmed and participants judged the river as muddier when the causality was instructed. These data give practical indications for legal judgments in a court.

    The current study examined age-related differences on three categorization tasks, a single-dimensional rule-based, a disjunctive rule-based, and a similarity-based task, and tested the effect of verbalization before categorization trials. As previous papers demonstrate, older adults find the disjunctive rule-based categories more difficult to learn than family resemblance-based categories, in contrast to younger adults. A simple pre-learning verbalization of category exemplars led to poorer learning performance on disjunctive rule-based learning for both age groups. Hand movement data collected by mouse tracking revealed that the disjunctive rule-based categories, which were difficult to older adults, involved huge competitive interferences, implying that younger adults experienced heavy inhibition loads in learning such categories. The data support the dual system model of category learning that there are different mechanisms for rule-based and non-rule based categories, and that the differential age-related performance decline in disjunctive categories can be due to the declines in inhibitory functions by aging.

    Recently, various studies have clarified that humans can immediately make social evaluations from facial appearance and that such judgment have an important role in several social contexts. However, early development of this skill has not been well investigated. In the current study, we used computer-generated Caucasian faces to assess the universality of perceiving facial impressions in Asian children. According to the previous studies, it is possible that there could be both universality and some cultural differences depends on the kind of impressions. We found some differences in the development of impression formation. In sum, trustworthiness and dominance judgment become more consistent as glowing up whereas competence judgment could be more difficult to the children. Together with the adults’ data, there could be some differences among cultures and ages. It is possible that there are various information which induce various impressions and the detectability of information should varies by the impressions.

    In this study, judgment of the width required to be able to pass through the aperture was measured. In a situation where observation distance was temporarily widened by attaching cubes, the passable width of the aperture was investigated. The results indicated that passable width judged by participants was overestimated when the observation distance was far.

    In the previous studies about the goodness of the tempo of the music, relations of the music known, the relations with the heart rate, influence of the speed of the tempo itself have been investigated. However, there is a little study considered about the relations with contents of the music. In this report, three music which have different tempo were selected for the test, and those tempi were changed into 85, 90, 95, 100, 105, 110, 115% of each original tempo. The goodness of these tempi was evaluated for these musical excerpts. As a result, for slow music (Lento ma non troppo), there was not the influence of the increase and decrease of the tempo, and for the intermediate tempo music (Allegretto), the rating value was the highest at an increase of 5% in the original tempo. For the fast music (presto), the rating value had step like function features such as the value was high at equal or more than the original tempo than the lower one. This result indicates that the tempo of the music had different properties on tempo preference.

    Previous studies have suggested that experiences in VR can replace the experiences in real life. However, it is possible that the experience in real may affect the "presence" of experience in VR. Previous studies have shown that time evaluation does not differ between VR and reality. The purpose of this study was to examine whether there was a difference in the time evaluation when experiencing bungee jump in VR depending on whether bungee jump was experienced.

    Participants were asked to put on a Head-Mounted Display to enjoy the bungee jump in VR and to measure the time until they rebound in bungee jump in VR.

    As a result, it has been found that those who have ever experienced bungee jump evaluate time longer in bungee jump in VR than those who have not. We further discuss the result from the viewpoint of time estimation.

    The purpose of this study was to examine the effect of the ease of pulling wet wipes on product impression. Study subjects were asked to use high-pulling-property and low-pulling-property wet-wipe products for cleaning. After each cleaning, the subjects evaluated the perceived pulling property, perceived wiping property, fun of using etc. of each product. Results showed that the high-pulling-property product was evaluated higher than the low-pulling-property product for both perceived pulling property and fun of use. Interestingly, the subjects who believed that the high-pulling-property product was easier to pull than the low-pulling-property product reported that former gave a smoother wiping experience, despite the wet wipes being the same in each product. We assumed that these findings were derived from the attribution of increasing haptic perceptual fluency (i.e., the increasing pulling property of the wet wipes) to product impressions.
