This study ontogenetically examined the relation between the ability of speech and gesture production. Four-year-old preschoolers, 5-year-old preschoolers, 1-3rd graders, 4th-6th graders, and university students (N=56) were instructed to explain a swing and a slide verbally. Their explanation was video-recorded and analyzed. The results showed that, although the total duration of speech production increased linearly as a function of age, the frequency of gestures changed tracing a U-shaped pattern. Gesture production decreased in school children but not in university students. Each group produced gestures different from those of other participants with regard to the pattern. Beats were produced only by university students while the viewpoint of gestures and speech-gesture relations differed between groups. Only university students produced gestures regarded to be profoundly related to language competence. Gestures produced during the early period of human development were considered complementary to language competence, while those produced by adults were seen as redundant to their speech.

In this study, effects of self touching behavior on the performance of lexical retrieval were investigated. In Experiment 1, 52 women were required to retrieve Japanese idioms, and to recall them approximately 2 minutes after the retrieval. The participants were randomly assigned into two groups; in one group, they were tested with the restriction of their hand movement, whereas in the other group, they were allowed to move their hands freely. Results revealed that when the movement was restricted, their performance in the retrieval task was significantly deteriorated. In Experiment 2, after the presentation of tape-recorded verbal stimuli, 26 women were required to recall them either with an interval of 2 minutes or with an interval of 2 weeks. The self-touching behavior was found to occur more often when the recall was performed with the interval of 2 weeks than when it took place immediately after the stimulus presentation. Thus self-touching is considered to serve as a cue to retrieve information stored in the long term memory.
