Difficulties with number sense can make it much more difficult to learn mathematical skills. Little is known about babies\u2019 ability to detect change in quantity. Previous research has focused on babies\u2019 ability to detect changes in large quantities and in visual experimental designs. The first aim of the thesis was to find out whether newborns and six-month-olds detect change in quantity between numbers two and one as well as two and three. The second aim of the thesis was to investigate what latency changes occur in the brain responses arising from detection of change in quantity during the first six months of person\u2019s life. \nThis thesis is part of the EarlyMath project\u2019s Baby sample. A total of 55 babies participated in the study of which 31 had participated in both newborn and six-month measurements. For the first research question, data from 47 newborns and 39 half-year-olds were used. For the second research question, data from 31 babies who participated in both research sessions were utilized. EEG was measured 2\u20133 weeks after the due date and at six months of age. Change detection for a quantity was analyzed using repeated measures ANOVA which was done separately for seven approximately 100 msec intervals on channels P3 and P4. The age effect was analyzed using repeated measures ANOVA and Pearson's correlation.\nOnly newborns\u2019 responses to the 2-part standard stimulus and the 1-part deviant stimulus differed statistically significantly. Six-month-olds showed no statistically significant differences between the stimuli. In newborns, the deviant response arising from a 1-part stimulus was dominated by a slow positive wave. At six months of age, the MMR response began to resemble the adult-like MMN response. Late time frames for 3-part stimulus in newborns were positively correlated with early time frames at six months of age on channel P3. \nNewborns detected the change between the numbers two and one, but not between the numbers two and three. The lack of statistically significant results for six-month-olds may be due to several reasons. The MMR response that occurs in newborns no longer occurs in six-month-olds, and the latency of change detection shifts earlier. Babies\u2019 ability to detect change in small quantities must be studied more in the future with as diverse experimental designs as possible.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2024-08-23T06:14:10Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2024-08-23T06:14:11Z (GMT).
