Preprint
Aphantasia is a characteristic in which people with normal perception have difficulty constructing their imagination. Most previous studies have used the Vividness of Visual Imagery Questionnaire (VVIQ), with some using self-identification of the absence of visual imagery, but there is a discrepancy between the proportions of aphantasia in the popu...

In order to examine whether syntactic processing is a necessary prerequisite for semantic integration in Japanese, cortical activation was monitored while participants engaged in silent reading task. Congruous sentences (CON), semantic violation sentences (V-SEM), and syntactic violation sentences (V-SYN) were presented in the experiment. The parti...

The present study conducted two event-related potential experiments to investigate whether readers adapt their expectations to morphosyntactically (Experiment 1) or semantically (Experiment 2) anomalous sentences when they are repeatedly exposed to them. To address this issue, we experimentally manipulated the probability of occurrence of grammatic...

The present study reported an experiment examining whether both native speakers (NSs) and non-native speakers (NNSs) give formulaic sequences (FSs) priority over novel phrases in processing, as the dual route model has postulated. In this experiment, NSs and NNSs were asked to read Japanese versions of semi-transparent restricted collocations (e.g....

This short note explains how to display Japanese in Psychtoolbox, which runs on GNU Octave, where no explicit method has been shown so far.
Method
Full-text available
Owing to the efforts of EEGLAB development team, we now can run EEGLAB withouth MATLAB, finally. It really helps many researchers/students at the situation of remote work.
Article
Full-text available
Reliably and efficiently detecting physiological differences between conditions of interest is of importance in psychophysiology. In particular, when it comes to the observation of relatively small differences, such as a P600 effect, a language-related brain potential elicited by ungrammatical sentences compared to grammatical sen- tences, inter-pa...

Our study aimed to examine the effects of pattern complexity on visual short-term memory (VSTM) at the retrieval stage in typical developing adults with different autism spectrum quotient (AQ) scores. Participants underwent electroencephalography during a same-different task, in which they judged as rapidly and accurately as possible whether the ta...

Full-text available
In many languages with flexible word order, transitive sentences in which the subject precedes the object have been reported to have a processing advantage during sentence comprehension compared with those in which the subject follows the object. This observation brings up the question of why this subject-before-object (SO) order should be preferre...

Full-text available
The processing load of sentences with different word orders in the Kaqchikel Mayan language was investigated using event-related potentials. We observed a P600 for subject-verb-object and verb-subject-object sentences as compared to verb-object-subject (VOS) sentences, suggesting that VOS order is easier to process than the other orders. This is co...
Article
Full-text available
We examined the effects of complexity on the efficiency of pattern encoding in the general population differing on autism-spectrum quotient (AQ) scores. We compared brain activity (electroencephalography) during a same-different task for High and Low AQ groups. The task was composed of identical comparison and categorical comparison (CC) conditions...

A previous behavioral study showed that a group of individuals with high vividness of visual imagery (High group), as determined from the score for the Vividness of Visual Imagery Questionnaire (VVIQ), could perceive the apparent motion path more strongly than a group of individuals with low vividness of visual imagery (Low group). To examine the p...
Article
In comprehending a meaning of a sentence, the sentence processor has to determine the relationship between case-marked noun phrases and verbs. Several studies claim that the sentence processor performs that decision process before the input of the verb by using some available information such as case markers. In Japanese, two kinds of case markers...
Article
Recording Event-Related Potentials, we investigated the processes from the input of a numeral quantifier (NQ) to the input of its host-NP to be integrated with the NQ. Experimental results showed that sustained anterior negativity was elicited between the input of a NQ and the input of its host-NP. In addition, the P600 was elicited after the input...
Article
A dependency establishment process is a successive procedure that readers use to determine the syntactic dependency between two or more elements. This study investigates when and how the readers make a decision on such dependency during on-line sentence processing, especially when they read sentences including numeral quantifiers in Japanese. In Ja...
Article
The genitive marker "no" in Japanese simple sentences often behaves as a conjunctional marker, connecting nouns ("[N nihongo]-no [N hon]") or a clause and a noun ("[S dochira-o saguru-ka]-no [N mondai]"). Therefore, when the sentence processor encounters "no", it can predict the subsequent appearance of a phonetic entity representing a noun. This s...
