Second, we tested adult samples and selected reliable and valid items for the revised CVT (CVT-R). Third, we used a neutral tone of voice for the stimuli. We then examined awareness of Gricean maxim violations in 4�C6-year-olds and adults, to compare maxim understanding across age. We hypothesized that children and adults would be most aware of the violations of the maxim of relation. We also hypothesized that the detection of violation of any [http://en.wikipedia.org/wiki/Megestrol_acetate Megestrol Acetate] maxim would be especially difficult for 4-year-old children, because both monolingual and bilingual 4-year-olds have been found to exhibit less understanding of all maxims than older children (Siegal et al., 2009). Moreover, children aged five or older who have an understanding of theory of mind (Perner et al., 1987; Wellman et al., 2001) may begin to show an understanding of pragmatics, because these two abilities are closely related (Happe, 1993). Method Participants Participants included 21 adults (M = 25.2 years, SD = 4.23; 10 males) and 64 preschoolers: 18 four-year-olds (M = 51.44 months, SD = 3.50, range [http://www.selleckchem.com/products/PD-0332991.html PD-0332991 order] = 47�C59 months; 8 males), 23 five-year-olds (M = 65.2 months, SD = 3.77, range = 60�C71 months; 12 males), and 21 six-year-olds (M = 75.7 months, SD = 2.75, range = 72�C81 months; 10 males). Children were recruited from kindergartens and nursery schools in Hyogo and Osaka prefectures. Data from one of the 4-year-olds were excluded from analysis because of experimental error, and data from a 6-year-old who refused to complete the task were also excluded. Therefore, data from 62 of the 64 preschoolers were included in the analyses. The design and purpose of the study were explained to the head administrators of the kindergartens and nursery schools, and their permission was obtained orally.
