Inhibition is one of the cognitive functions and it has an essential role in our ability to adjust our behavior. The aim of our thesis was to study the differences between adults\u2019 and children\u2019s inhibitory processes and through that obtain possible important developmental markers. \n Our analysis included 74 participants, out of which 58 were children (ages 6\u201314) and 16 adults. We studied time frames in which inhibitory auditory processing is visible in both adults\u2019 and children\u2019s induced responses. Additionally, we wanted to see if there is a difference between adults\u2019 and children\u2019s induced responses when they perform two auditory tasks: a passive listening task and an auditory Go/NoGo task. We also wanted to know if there\u2019s a difference in brain activity and induced responses between the hemispheres of the brain.\n\nThe results were that there was no difference in the children\u2019s induced responses between the passive listening task and the Go/NoGo task at the 400\u20131200 ms time frame and at 5\u201329 Hz frequency. A statistically significant difference was found in the adults\u2019 induced responses between the same tasks using the same time frame and frequency. The adults had stronger brain activity in the Go/NoGo task compared to both the adults\u2019 passive listening task and the children\u2019s Go/NoGo task. Also, there was a significant difference in the adults\u2019 brain activity between the right and left hemisphere, but this difference was not found in the children\u2019s results.\n\nOur research suggests that the stronger induced responses that were found in adults\u2019 brain activity are a possible marker of advanced inhibition. Future research could focus on specifying this possible marker as well as mapping out the age period in which brain responses begin to develop and mature for tasks that require auditory inhibitory processing.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2022-10-26T05:29:57Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-10-26T05:29:58Z (GMT).
