Tulosten perusteella semanttinen manipulaatio toimi odotusten mukaisesti kaikilla ik\u00e4ryhmill\u00e4: kun semanttinen odotus rikottiin, vasteet voimistuivat.

In order to do this, auditory evoked neural responses to semantically matching and non-matching picture-word pairs were recorded using magnetoencephalography (MEG) method. Responses from the left and the right hemisphere were analysed separately. The N400m, response consistently associated with semantic processing, was compared across three age groups of typically developing children (6-7, 9-10 and 12-13 year olds, N = 32) and adults (N = 10). In general the semantic manipulation appeared as expected in all age groups: when the semantic expectation was violated, the responses were enhanced. However, many differences between children and adults were found in timing and hemispheric distribution of semantic processing. First, the younger the child, the longer the latencies and durations of neural responses were. Second, an age-related shift from more bilateral or right hemisphere lateralised to more left-hemisphere lateralised semantic processing was detected. Third, the influence of semantic priming to neural network efficiency in matching condition was weaker in all child groups in comparison to adults. Adolescents in this study displayed an adultlike activation pattern with respect to strength, timing and lateralisation of semantic effect. This suggests that the clearest developmental changes in semantic processing take place at around 10.5-12 years of age. This study adds to the growing body of evidence that the maturation of mechanisms underlying semantic processing continues well into school age. The findings on developmental lateralisation underscore the importance of using spatially accurate methods such as MEG when studying semantic processing.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Miia Hakanen (mihakane) on 2016-02-29 10:22:19.510131.
