Abstract Objective The continuous performance tests (CPTs) are the gold standard to assess vigilance or sustained attention. Many studies have shown that educational level is significantly associated with performance on the CPTs. However, very few studies have made comparisons that included cultural factors (Miranda et al, 2008). Given the breadth of educational systems in different parts of the world, it could be expected that the effect of educational level will vary depending on the culture of origin. The aim of this study was to examine the effect of education on performance on a CPT task in 3 ethnically diverse groups (Hispanic, Non-Hispanic and Spanish). Participants and Method This study includes 57 participants in the EMBRACED project: 12 Hispanic Americans, 26 non-Hispanics Americans, and 19 Spaniards (8.3%, 30% and 57% with high education respectively). Educational level was defined as high (university degree and above) or low (less than a university degree). The EMBRACED CPT is computerized and demands the participant to touch the iPad screen each time a target is presented. In 3 blocks of 100 stimuli each, the number of hits, omissions, and commissions is recorded. Results A mixed between-within subjects analysis of variance was conducted to compare scores in the three blocks of the CPT in relation to the three cultural groups and by education levels. Results showed no interaction effects between cultural groups and education, and no main effects of education for any of the studied variables. However, there was a significant main effect for cultural group for hits (F = 4.676, P = .014) and omissions (F = 5.614, p = .006). Conclusions The overall results for education in this study were not significant and would need further study. The variability in cultural group revealed a consistent effect across all studied variables. The non-Hispanics scored higher in hits and the Spaniards had more omissions. These results justify the need for cultural adaptation of neuropsychological measures. References Miranda, M. C., Sinnes, E. G., Pompeia, S., & Francisco Amodeo Bueno, O. (2008).

Relationships among continuous performance test, IQ, achievement, and memory/learning scores were explored in a clinical sample of 1,280 children ( M age = 9.4 years, M grade = 3.9). Intercorrelations among CPT measures were significant, but modest. Correlations between CPT measures and IQ, achievement, and memory/learning scores were also significant, but again generally weak. The CPT number correct scores were more strongly related to other cognitive measures than were commission (i.e., responding to incorrect stimuli) scores. The breadth and extent of associations among the CPT measures and the various cognitive/academic tasks suggest that all, to some extent, require attention and inhibition. The importance of routinely assessing attention and disinhibition in psychological testing is discussed.

Abstract Contingent negative variation (CNV) and evoked potentials were recorded during the continuous performance test in 20 children (aged 7 to 12) with attention deficit/hyperactivity disorder (ADHD) and in 19 age-matched healthy children. A series of letters were displayed every 2.1 s and a button had to be pressed whenever the letter O was followed by an X. Children were also given neuropsychological tests and questionnaires assessing anxiety and depression. Unlike ADHD children, healthy children showed a more pronounced CNV after the cue - the letter O - than after the distractors. At Fz, CNV negativity was significantly correlated with IQ and executive function. Control children also exhibited a higher parietal N375 post S1 - likely to be associated with letter processing - and a higher N550 amplitude at Fz than ADHD children post S1 and S2; both groups showed a higher N550 amplitude whenever X followed non-O or O was followed by non-X. This component appears to be involved in decision-making processes regarding the initiation or inhibition of movement. ADHD children had a faster reaction time but made more errors of omission and commission. Results suggest that ADHD children show deficits in both stimulus processing and response execution.

Adaptive Rate

An adaptive-rate Continuous Performance Task for the assessment of human performance has been developed based on the original method of Rosvold, et al. (1956). The stimulus presentation speeds up after correct detections and slows down after errors of omission or commission, allowing applications in a wide range of clinical populations and normal age groups. Adequate error rates are obtained to characterize each individual's performance. Signal detection analysis yields d′ and β parameters with adequate test-retest reliability over 6 mo. A specific decline in a′ over time is consistent with other studies of human vigilance.

Zusammenfassung Fragestellung: Gibt es neurophysiologische Korrelate der Aufmerksamkeitsstörung beim hyperkinetischen Syndrom (HKS) und welche Bedeutung haben diese für die Ätiologie der Störung. Methodik: Selektive Aufmerksamkeitsprozesse wurden anhand des zweistufigen Continuous Performance Test (CPT) bei 18 Jungen mit hyperkinetischem Syndrom (HKS) untersucht und mit einer nach dem Alter parallelisierten Kontrollgruppe von 21 Jungen verglichen. Die Altersspanne der Stichprobe betrug 6 bis 12 Jahre. Parallel dazu wurden ereigniskorrelierte Potentiale (EKP) während des Tests an den Elektrodenpositionen Fz, Cz, Pz und Oz mit Referenz zu verbundenen Ohren abgeleitet. Ergebnisse: Im EKP nach dem präparatorischen Stimulus konnten zwei Komponenten der Contingent Negative Variation (CNV) mit unterschiedlicher topographischer Verteilung identifiziert werden (CNV-1: 600 bis 1100 ms und CNV-2: 1000 bis 1500 ms nach Stimulus). Die Stichproben unterschieden sich nicht auf der Verhaltensebene (Fehlerrate und Reaktionszeit). Signifikante Gruppenunterschiede ergaben sich hinsichtlich der Topographie der beiden CNV-Komponenten. Kinder mit HKS zeigten im Vergleich zu Kontrollkindern eine signifikant niedrigere CNV-1 über der frontalen und eine Tendenz zu stärkerer Negativierung (CNV-1 und CNV-2) über der occipitalen Elektrode. Schlussfolgerungen: Die Ergebnisse unterstützen die Hypothese einer Unterfunktion frontaler inhibitorischer Prozesse bei Kindern mit HKS.

Abstract. Several studies have shown that Continuous Performance Tests (CPT) can diagnose Attention Deficit Hyperactivity Disorder (ADHD) better than other tests. Research reporting comparisons of two or more CPT-type tests is scarce. The purpose of the study was to compare the Mathematics Continuous Performance Test (MATH-CPT) with another CPT-type test (CPT II) and a questionnaire (the Brown Scale). The comparison was carried out by looking at correlations among subscales and checking the precision of detecting ADHD. Ninety-five high school and college students participated in the study, 41 with ADHD were the research group and 54 were the control group. The participants performed the two tests and answered the questionnaire. The results showed that the MATH-CPT correctly identified 74.50% of the participants of both groups as compared to the 71.60% of the CPT II. Correlations between the two CPT-type tests were moderate; however, they were similar to correlations found in other studies comparing similar tools. The MATH-CPT, final attention formula, showed significant correlations with the Brown scales, while the CPT II, confidence index associated with ADHD assessment, showed nonsignificant correlations with the questionnaire. The study indicated that MATH-CPT can be used with a clinical population of ADHD and for research purposes.
