This paper reports findings from an ongoing study investigating turn length and backchannel responses in dyadic conversations in British Sign Language (BSL) and their relationship to social factors, such as age and gender. Previous research has revealed gender differences concerning turn length and frequency of backchannel responses. For example, it is reported that male English speakers tend to hold the floor longer than women in mixed-sex dyads (Coates, 2004) and that men and women’s backchannel behaviour (e.g., nodding, shaking the head, making small vocalisations such as ‘hmm’ or ‘yeah’, see Duncan (1974)) differ in same sex and mixed sex dyads (Bilous & Krauss, 1998). The relationship between gender and backchannel use is, however, reported to vary over time and according to culture, language and discourse type (Feke 2003, Dixon & Foster 1998). Although few studies have examined turn length and backchannel responses using signed language data, some findings have been reported. Nowell (1989) found no differences in time spent signing in six American Sign Language (ASL) mixed-sex dyads during interviews as well as no differences in signed backchannels. In contrast, a small-scale pilot study into BSL suggested that men produce fewer non-manual backchannels in conversations than women (Sutton-Spence, 2000). Additionally, Mesch et al. (2011), investigating Swedish Sign Language found that younger signers produced fewer backchannels than older signers. This paper reports findings from a study in progress investigating these aspects of conversational behaviour in 30 informal British Sign Language (BSL) conversations (taken from the BSL Corpus Project, see Schembri et al., 2011) in mixed sex and single sex dyads involving older and younger deaf native and non-native signers (60 participants in total). Using ELAN, we coded ten minutes of each conversation, noting when each signer had the floor, and marking any time the addressee made any manual or non-manual backchannel response. All annotated data were then exported and analysed using Rbrul multivariate statistical software An overall analysis involving all 60 signers suggested no significant differences in the amount of time spent signing by signers of either gender in same sex or mixed dyads However, we did find older signers (50 and above) prefer significantly longer turns. Furthermore, a preliminary analysis based on 30 signers revealed no significant differences between gender and age groups in the amount of time spent on manual or non-manual backchannels. It appears that female dyads spent longer nodding than male or mixed dyads, although this difference was not found to be significant. This paper will present a complete analysis of non-manual and manual backchannels (incorporating the remaining 50% of the dataset) outlining any potential effects due to social factors. These findings appear to suggest that, unlike English, sociolinguistic variation in conversational behaviour in BSL may not be conditioned by gender. We conclude by discussing the implications of this study for the sociolinguistics of signed and spoken languages. . References Baker, C. (1977).
