    Abstract: Numerous studies show that children's language ability is related to false-belief understanding. However, there is considerable variation in the size of the correlation reported. Using data from 104 studies (N=8,891), this meta-analysis determines the strength of the relation in children under age 7 and examines moderators that may account for the variability across studies--including aspect of language ability assessed, type of false-belief task used, and direction of effect. The results indicate a moderate to large effect size overall that remains significant when age is controlled. Receptive vocabulary measures had weaker relations than measures of general language. Stronger effects were found from earlier language to later false belief than the reverse. Significant differences were not found among types of false-belief task.

    Abstract: System-initiated digressive proposals may be used to introduce new and unexpected information into automated telephone services. These digressions may be viewed as particularly pronounced forms of unsolicited interruptions as they contain information not directly related to the caller's intended activity. In human-human conversation, interruptions are considered to be speech acts which intrinsically threaten both the positive and negative face wants of the addressee and conversants adopt specific verbal strategies to mitigate the negative impact of their interruptions. A question therefore arises whether the introduction of face redressive expressions, based on human-human conversational strategies, into the design of system-initiated proposals in automated services can mitigate the negative impact of the interruptions. A usability experiment was conducted to examine the effectiveness of three contrasting politeness strategies for system-initiated digressions in a mass-market telephone banking dialogue using speech recognition technology. Participants (N= 111) experienced these proposals while using the automated service to perform banking tasks. Results indicated that all these system-initiated digressions-irrespective of politeness strategy employed-had a negative impact on the user attitudes towards the service. This paper reports these results and explores participants' perceptions of the politeness styles and registers employed in the system-initiated proposals.
