“…Further, a recent study combined use of the electroencephalogram (EEG) and CPT in an examination of children aged 9–11 years 20 and normal adults 21 . Studies involving the use of event‐related potentials (ERP) and CPT in children aged 12–17 years 22 have also been reported.…”

Aim:The development of attention function in children is still not sufficiently clear. Although it is difficult to objectively assess attention function, continuous performance tests (CPT) can be used to objectively assess cognitive function along with attention. The development of cognitive and attention functions was examined in children using a CPT.Methods: A total of 541 healthy girls aged 5-12 years participated. Ten parameters were calculated: numbers of cancellations for either target stimuli (T-cancel) or non-target stimuli (N-cancel), numbers of omission errors (Omission) and commission errors (Commission), hit rate (Hit), false alarm rate (False), mean reaction time for correct response (RT), coefficient of variance for mean reaction time (CVRT), sensitivity index (d′), and lnb. Results:The parameters were divided into three types based on pattern of change. T-cancel, False, and Commission, which are related to inhibition of response, N-cancel, Hit, and Omission, which are related to inattention to stimuli, and CVRT, which is related to stability of processing time, exhibited significant change until 5 or 6 years of age. d′, which is related to ability to discriminate between target or non-target, exhibited significant change until 8 years of age. RT, which is related to processing time, exhibited significant change until 11 years of age. lnb exhibited no significant differences among age groups. Conclusions:These findings indicate that inhibition function, inattention to stimuli, and stability of processing time develop first. Discrimination ability subsequently increases based on these developments, and finally processing time is reduced.

“…Also, it could be the reflection of a contingent negative variation triggered by the warning signal itself. Earlier reports seem to offer support for any one of these notions (Strandburg et al, 1996;González-Garrido et al, 2001). Whatever the theoretical alternative might be, they all do seem to point to the probable failure of the injured children to efficiently use relevant contextual information.…”

“…One of the most commonly used odd-ball, go-no go paradigms is the Continuous Performance Test (CPT), which has often been administered to evaluate sustained attention and working memory processing resources (González-Garrido, Gómez-Velázquez, Fernández-Harmony, Oropeza, & Ruiz-Sandoval, 2001;Straube, Bischoff, Nisch, Sauer, & Volz, 2002;Suchan, Pickenhagen, & Daum, 2005;Moustafa, Sherman, & Frank, 2008).…”

Event-Related Brain Potentials Depict Cognitive Disturbances in Children with Mild Traumatic Brain Injury

Mild traumatic brain injury (MTBI) is a common cause of short-term cognitive disturbances in children that rarely are related to objective neurophysiological markers. With the aim of correlating cognitive processing with event-related brain potential variation, visual Continuous Performance Tests (CPT) were administered to 15 children with MTBI and a matched control group. All the patients had suffered post-traumatic loss of consciousness lasting less than 15 minutes, and they were evaluated within 5-to-15 days post-trauma. A few additional neuropsychological tests were also administered to both groups. Behavioral results showed that the injured children achieved poorer scores for phonological and verbal fluency tasks and no interference effect in a computerized version of the Stroop test. They had fewer correct responses on CPT-AX, where a warning signal preceded targets. The N90, P240 and P390 ERP components varied significantly between groups while performing CPT-AX. Present findings could be interpreted as reflecting disturbances that impede injured children from using contextual information efficiently. The higher amplitude of the slow late positivity observed in the control group might reflect updating memory preparatory processes that could increase subsequent cognitive operational competence. The ERP assessment could be helpful to demonstrate early neurophysiological disturbances subsequent to a MTBI in children.
