This paper examines how and by whom tellings with two young children are triggered at ages 23, 36 and 42 months. The data for the investigation is derived from a larger Australian English corpus of over 50 hours of interactions in the home, although one of the children is a bilingual Italian/ English-speaking child. The data is derived from two parent/child dyads, and in the case of the child aged 42 months, a triadic interaction between a mother, her own child and a second child. Using the micro-analytic methods of conversation analysis, the study analyses five samples of tellings. The first two describe how a child, Cassandra, aged 23 months, is invited to recount events of her day by her parents. The trigger for these tellings is the social activity of sharing everyday routine events. The next two samples focus on Rosie at 36 months who is also invited to share a telling by her parent about a birthday party celebration and one about a neighbourhood cat, Claude. The first telling is triggered by an object, a balloon from a birthday party from the day before, while the second is triggered by play involving the character of a cat, initially derived from a favourite story, Hairy Maclary. In the final sample, Cassandra, aged 42 months, initiates a telling about an experience at her grandmother’s which is trigged by a picture in a book. The analyses in each case reveal the interactional issues that arise in the action of telling and how these are dealt with by all participants. By focusing on the three ages, key features in the children’s participation in storytelling are uncovered.

The Individual

Collectivistic orientation, which entails interdependent self-construal and concern for interpersonal harmony and social adjustment, has been suggested to be associated with detecting emotional expressions that signal social threat than individualistic orientation, which entails independent self-construal. The present research tested if this detection is a result of enhanced perceptual sensitivity or of response bias. We used country as proxy of individualism and collectivism (Country IC), measured IC of individuals with a questionnaire (Individual IC) and manipulated IC with culture priming (Situational IC). Dutch participants in the Netherlands (n = 143) and Chinese participants in China (n = 151) performed a social threat detection task where they had to categorize ambiguous facial expressions as “angry” or “not angry”. As the stimuli varied in degrees of scowling and frequency of presentation, we were able to measure the participants' perceptual sensitivity and response bias following the principles of the Signal Detection Theory. On the Country IC level, the results indicated that individualism-representative Dutch participants had higher perceptual sensitivity than collectivism-representative Chinese participants; whereas, Chinese participants were more biased towards categorizing a scowling face as “angry” than the Dutch (i.e. stronger liberal bias). In both groups, collectivism on the Individual IC was associated with a bias towards recognizing a scowling face as “not angry” (i.e. stronger conservative bias). Culture priming (Situational IC) affected neither perceptual sensitivity nor response bias. Our data suggested that cultural differences were in the form of behavioral tendency and IC entails multiple constructs linked to different outcomes in social threat detection.

Phonological Contrasts

Abstract While voicing contrasts in word-onset position are acquired relatively early, much less is known about how and when they are acquired in word-coda position, where accurate production of these contrasts is also critical for distinguishing words (e.g., do g vs. do ck ). This study examined how the acoustic cues to coda voicing contrasts are realized in the speech of 4-year-old Australian English-speaking children. The results showed that children used similar acoustic cues to those of adults, including longer vowel duration and more frequent voice bar for voiced stops, and longer closure and burst durations for voiceless stops along with more frequent irregular pitch periods. This suggests that 4-year-olds have acquired productive use of the acoustic cues to coda voicing contrasts, though implementations are not yet fully adult-like. The findings have implications for understanding the development of phonological contrasts in populations for whom these may be challenging, such as children with hearing loss.
