In order to produce a coherent narrative, speakers must identify the characters in the tale so that listeners can figure out who is doing what to whom. This paper explores whether speakers use gesture, as well as speech, for this purpose. English speakers were shown vignettes of two stories and asked to retell the stories to an experimenter. Their speech and gestures were transcribed and coded for referent identification. A gesture was considered to identify a referent if it was produced (...) in the same location as the previous gesture for that referent. We found that speakers frequently used gesture location to identify referents. Interestingly, however, they used gesture most often to identify referents that were also uniquely specified in speech. Lexical specificity in referential expressions in speech thus appears to go hand‐in‐hand with specification in referential expressions in gesture. (shrink)

Sound-symbolism is the nonarbitrary link between the sound and meaning of a word. Japanese-speaking children performed better in a verb generalization task when they were taught novel sound-symbolic verbs, created based on existing Japanese sound-symbolic words, than novel nonsound-symbolic verbs (Imai, Kita, Nagumo, & Okada, 2008). A question remained as to whether the Japanese children had picked up regularities in the Japanese sound-symbolic lexicon or were sensitive to universal sound-symbolism. The present study aimed to provide support for the latter. In (...) a verb generalization task, English-speaking 3-year-olds were taught novel sound-symbolic verbs, created based on Japanese sound-symbolism, or novel nonsound-symbolic verbs. English-speaking children performed better with the sound-symbolic verbs, just like Japanese-speaking children. We concluded that children are sensitive to universal sound-symbolism and can utilize it in word learning and generalization, regardless of their native language. (shrink)

We investigated whether the inferior parietal lobule (IPL) responds in real-time to multisensory inconsistency during movement. The IPL is thought to be involved in both the detection of inconsistencies in multisensory information obtained during movement and that obtained during self-other discrimination. However, because of the limited temporal resolution of conventional neuroimaging techniques, it is difficult to distinguish IPL activity during movement from that during self-other discrimination. We simultaneously conducted electroencephalography (EEG) and near-infrared spectroscopy (NIRS) with the goal of examining IPL (...) activity with a high spatiotemporal resolution during single reaching movements. Under a visual feedback-delay condition, gamma event-related synchronization (γ-ERS), i.e., an increase in gamma (31–47 Hz) EEG power, occurred during reaching movements. This γ-ERS is considered to reflect processing of information about prediction errors. To integrate this temporal information with spatial information from the NIRS signals, we developed a new analysis technique that enabled estimation of the regions that show a hemodynamic response characterized by EEG fluctuation present in the visual feedback-delay condition. As a result, IPL activity was explained by γ-ERS specific to visual feedback delay during movements. Thus, we succeeded in demonstrating real-time activation of the IPL in response to multisensory inconsistency. However, we did not find any correlation between either IPL activity or γ-ERS with the sense of agency. Therefore, our results suggest that while the IPL is influenced by prediction error signals, it does not engage in direct processing underlying the conscious experience of making a movement, which is the foundation of self-other discrimination.

We examined whether children's ability to integrate speech and gesture follows the pattern of a broader developmental shift between 3- and 5-year-old children regarding the ability to process two pieces of information simultaneously. In Experiment 1, 3-year-olds, 5-year-olds, and adults were presented with either an iconic gesture or a spoken sentence or a combination of the two on a computer screen, and they were instructed to select a photograph that best matched the message. The 3-year-olds did not integrate information in (...) speech and gesture, but 5-year-olds and adults did. In Experiment 2, 3-year-old children were presented with the same speech and gesture as in Experiment 1 that were produced live by an experimenter. When presented live, 3-year-olds could integrate speech and gesture. We concluded that development of the integration ability is a part of the broader developmental shift; however, live-presentation facilitates the nascent integration ability in 3-year-olds. (shrink)

Previous research has established that goal tracking emerges early in the first year of life and rapidly becomes increasingly sophisticated. However, it has not yet been shown whether young children continue to update their representations of others’ goals over time. The current study investigates this by probing young children’s ability to differentiate between goal directed actions that have been halted because the goal was interrupted, and because the goal was abandoned. To test whether children are sensitive to this distinction, we (...) manipulated the experimenter’s reason for not completing a goal-directed action - his initial goal is either interrupted by an obstacle, or it is abandoned in favour of an alternative. We measure whether children’s helping behaviour is sensitive to the experimenter’s reason for not completing his goal-directed action by recording whether they complete the experimenter’s initial goal or the alternative goal. The results showed that children helped complete the experimenter’s initial goal significantly more often after this goal had been interrupted than after it had been abandoned. These results support the hypothesis that children continue to update their representations of others’ goals over time by the age of two, and specifically that they differentiate between abandoned and interrupted goals.

Previous research has established that goal tracking emerges early in the first year of life and rapidly becomes increasingly sophisticated. However, it has not yet been shown whether young children continue to update their representations of others’ goals over time. The current study investigates this by probing young children’s (24-30 months old) ability to differentiate between goal directed actions that have been halted because the goal was interrupted, and because the goal was abandoned. To test whether children are sensitive to (...) this distinction, we manipulated the experimenter’s reason for not completing a goal-directed action - his initial goal is either interrupted by an obstacle, or it is abandoned in favour of an alternative. We measure whether children’s helping behaviour is sensitive to the experimenter’s reason for not completing his goal-directed action by recording whether they complete the experimenter’s initial goal or the alternative goal. The results showed that children (n = 24) helped complete the experimenter’s initial goal significantly more often after this goal had been interrupted than after it had been abandoned. These results support the hypothesis that children continue to update their representations of others’ goals over time by the age of two, and specifically that they differentiate between abandoned and interrupted goals.

A considerable body of research has documented the emergence of what appears to be instrumental helping behavior in early childhood. The current study tested the hypothesis that one basic psychological mechanism motivating this behavior is a preference for completing unfinished actions. To test this, a paradigm was implemented in which 2-year-olds (n = 34, 16 female/18 male, mostly White middle-class children) could continue an adult’s action when the adult no longer wanted to complete the action. The results showed that children (...) continued the adult’s actions more often when the goal had been abandoned than when it had been reached (OR = 2.37). This supports the hypothesis that apparent helping behavior in 2-year-olds is motivated by a preference for completing unfinished actions. (shrink)
