Aims: This study examined differences in corticocortical communication between adolescent ε4 carriers (ε4+) and noncarriers (ε4-) during a fluid intelligence task (Comprehensive Test of Nonverbal Intelligence [CTONI]). Methods: Sixteen ε4+ and 20 ε4- individuals aged 13-15 years performed the CTONI while real-time EEG signals were acquired. Inter- and intrahemispheric coherences were analyzed. Results: The ε4+ subjects exhibited lower inter- and intrahemispheric coherences than the ε4- individuals. Conclusion: ε4 carriers have lower corticocortical communication than noncarriers during an intelligence task, implying that carrying the ε4 allele may reduce brain networking in adolescence, several decades before the onset of Alzheimer disease.

Abstract Background Fluid intelligence deficits affect executive functioning and social behaviors in patients with schizophrenia. To help clinicians manage fluid intelligence deficits, a psychometrically sound measure is needed. The purposes of this study were to examine the test–retest reliability and convergent validity of the Test of Nonverbal Intelligence-Fourth Edition (TONI-4) assessing fluid intelligence in patients with schizophrenia. Methods A total of 103 patients with stable condition were assessed with the TONI-4 twice with a 4-week interval to examine the test–retest reliability. We further used the Montreal Cognitive Assessment (MoCA) and the Tablet-Based Symbol Digit Modalities Test (T-SDMT) to examine the convergent validity of the TONI-4. Results The intra-class correlation coefficient was 0.73 for the TONI-4. The percentages of standard error of measurement and minimal detectable change for the TONI-4 were 5.1 and 14.2%, respectively. The practice effect of the TONI-4 was small (Cohen’s d = − 0.03). Convergent validity showed small to moderate significant correlations between the TONI-4 and the MoCA as well as the T-SDMT (r = 0.35, p = .011 with the T-SDMT and r = 0.61, p < .001 with the MoCA). The results demonstrated that the TONI-4 had good test–retest reliability, limited random measurement error, and a trivial practice effect. The convergent validity of the TONI-4 was good. Conclusions These findings indicate that the TONI-4 has potential to be a reliable and valid assessment of fluid intelligence in patients with schizophrenia.

of nonverbal intelligence. The test was developed to assess the generalcognitive ability of Pakistani youth. The items were constructed keeping inmind to tab the cognitive domains of fluid intelligence, abstract reasoning,spatial ability, working memory, processing speed, inductive anddeductive reasoning, application of logics, drawing of inferences andrelated abilities. Multidimensional construct methods were used todetermine the construct validity. The principal factor analysis withvarimax rotations yielded a single factor loading, an indicative of unifactor test. Inter correlation of five subscales and total test scores werefound to be highly significant (p < .001). The results showed thehomogeneity of the test. The discrimination validity of the test wasestablished by correlating the test scores with test takers performance ontest of physical agility and stamina. The Pearson correlation produced nonsignificant results between the two measures. The criterion validity wasestablished by correlating the test scores with academic achievementswhich generated highly significant correlations at p < .001. The convergentvalidity was established by correlation the scores with Raven progressivematrices, verbal intelligence tests and nonverbal intelligence being used atinter services selection boards. The results showed coefficient ofcorrelation .384, .227 and .396 respectively for RSPM, VIT and NVITwhich was highly significant at p. < .001. The age and grade differencesalso showed that the mean test score increases with age and grade. Theresults of the validity studies indicate that the proposed nonverbal test is avalid measure to assess the intelligence of Pakistani youth.
