Foraging refers to behavior that exploits the current environment for resources and induces exploration for a better environment. Visual foraging tasks have been used to study human behavior during visual searches. Participants searched for target stimuli among the distractors and either acquired or lost points when they clicked on a target or…

Emotion labels can be helpful for creating emotion categories. Russell and Widen (2002) demonstrated the label superiority effect; that is, emotion labels produce a more precise categorization of emotional faces than the corresponding emotional faces. The current study aimed to test the label superiority effect on emotional voices and examined…

Research has shown that learning a known-and-unknown word combination leads to greater learning than learning an unknown word alone (Kasahara, 2010, 2011). These studies found that attaching a known adjective to an unknown noun can help learners remember the unknown noun. Kasahara (2015) found that a known verb can serve as an effective cue to…

This study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence--size, organization, and accessibility--and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three…

Atypical learning and memory in early life can promote atypical behaviors in later life. Less relational learning and inflexible retrieval in childhood may enhance restricted and repeated behaviors in patients with autism spectrum disorder. The purpose of this study was to elucidate the mechanisms of atypical memory in children with autism…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…

Intercultural simulations, such as Barnga (Thiagarajan & Steinwachs, 1990), along with the use of critical incidents (Gibson, 2002; Gropper, 1996), have long been a mainstay of intercultural communication courses and have found their way into English as a second language (ESL) and English as a foreign language (EFL) classrooms (Apedaile &…

Although the Word Associates Format (WAF) is becoming more frequently used as a depth-of-knowledge measure, relatively little validation has been carried out on it. This report of two validation studies tackles various important WAF issues yet to be satisfactorily resolved. Study 1 conducted introspective interviews regarding students' WAF…

This article examines the effects of synonymy (i.e., learning words with and without high-frequency synonyms that were known to the learners) on word knowledge in a study of 84 Japanese students learning English. It employed 10 tests measuring 5 aspects of word knowledge (orthography, paradigmatic association, syntagmatic association, meaning and…

This annual report discusses several topics related to the work of the Research and Clinical Center for Child Development. Six topics are covered in the report. The articles are: (1) "Development of Intentional Behavior in Early Infancy" (Hongtu Chen); (2) "An Investigation of the Differences of Social Space in the Playroom: Through…

English-as-a-Second-Language students in Japan were tested at the beginning and the end of the school year to examine changes in word associations and grammatical suffix knowledge. Results showed an average vocabulary gain of 330 words, a poor knowledge of the allowable suffixes for the verbs learned, and 19 to 25 percentage points more receptive…
