Characteristic Of Response Inhibition Abilities In Children With Two Subtypes Of Attention Deficit Hyperactivity Disorder

Since Barkley (1997) put forward defect of the response inhibition ability is thecore defect of ADHD children, the study of response inhibition ability characteristicsof ADHD children has been high-profile. Barkley divided response inhibition intothree aspects: Advantage response inhibition, response to stop and interference control.Because most studies investigated response inhibition ability of children with ADHDchildren’s from one aspect, this study comprehensively examine the characteristics ofADHD children in three aspects. Because the visual and auditory are important wayfor information processing, this study investigate ADHD children in both sensorychannel on cognitive ability.Through the methods of questionnaire investigation, interview, and DSM-Ⅳsubtype classification criteria, this study finally selected25hyperactive-impulsivechildren (ADHD-C),22attention defect children (ADHD-I) and28normal childrenas the research object of this study. And study the two subtypes of ADHD children’sresponse inhibition ability in all aspects of the characteristics on the visual andauditory sensory channels.Research one mainly inspect advantages response inhibition ability characteristicof two subtypes ADHD children in visual and auditory sensory channel through avisual and auditory Go/NoGo task. Research two mainly inspects response stop abilityof two subtypes ADHD children in visual and auditory sensory channel through thevisual and auditory Stop Signal task. Third research mainly inspects interferencecontrol characteristics of two subtypes ADHD children in visual and auditory sensorychannel through the visual presentation in classic color word stroop task and auditorypresentation in color objects stroop task.It is found that there is a difference between normal children and ADHD-C、ADHD-I children’s advantage response inhibition and state regulation ability in thevisual and auditory sensory channel. And in the visual sensory channel, there is adifference between ADHD-C and ADHD-I children’s Advantage response inhibitionability and state regulation ability; And there is a difference between ADHD-C、ADHD-I and normal children’s response stop ability in visual and auditory sensorychannel, but there is no difference between two subtypes of ADHD children. There isno difference between ADHD-C、ADHD-I and normal children’s interference controlability in visual and auditory sensory channel; there is a difference between ADHDand normal children’s reaction rate in auditory sensory channel. In conclusion, this studies the following conclusions:(1) the ADHD-C andADHD-I children exist a defect of response inhibition ability in both visual andauditory sensory channel and are not affected by the activated state. On the visualsense channel, the defect of ADHD-C children’s advantage response inhibition abilityis serious than ADHD-I.(2) The two subtypes of ADHD children’s response abilityexists defects in both visual and auditory sensory channel, and there is no differencebetween ADHD-C and ADHD-I children’s respond stop ability in two kinds ofsensory channel.(3) there is no defect of the interference control ability in both twosubtypes of ADHD children in the both auditory and visual sensory channel.(4) Thereexist state regulation ability defects of two subtypes ADHD children in both visualand auditory sensory channel. On visual sensory channels, the state regulation abilityof ADHD-I is serious than ADHD-C children, but showed no such characteristics onauditory sensory channel.(5) The reaction rate of ADHD children is not backward inauditory sensory channel. It is shows ADHD children’s reaction execute ability existsno defect in auditory sensory channel.
