Prior studies have consistently shown moderate associations between matrix performance and task-switching ability. However, these findings are largely based on correlational data. The present two-study article aimed to (a) determine, on a theoretical level, whether task-switching ability is functionally involved in matrix processing, and (b) assess, from a diagnostic perspective, whether relaxing the constraint of distinct rules within a single matrix threatens psychometric validity. To this end, we manipulated matrices to include both distinct-rule and identical-rule transitions, enabling experimental within-subject comparisons of matrix processing in both conditions based on log file analyses. In study 1 (<em>N</em> = 209), task-switching ability exerted a functional influence only during distinct-rule transitions. However, the correlation between task-switching ability and matrix performance remained comparably strong even during identical-rule transitions. This dual pattern supports both a switch-dependency hypothesis (i.e., that task-switching is functionally involved in matrix processing) and a shared-resource hypothesis (i.e., that task-switching and matrix processing draw on a common cognitive resource). In study 2 (<em>N</em> = 258), we evaluated the convergent validity of the newly designed mixed-rule format against the traditional distinct-rule format. Test scores were highly correlated (<em>r</em> = 0.87), and test characteristics (e.g., reliability, IRT and TIF parameters) and external validity were very similar. Taken together, these findings suggest that although task-switching demands can vary depending on matrix design, relaxing rule constraints does not compromise psychometric validity. This flexibility in item development may be particularly useful in large-scale assessments or student selection tests that require continuous item renewal.</div></div>","PeriodicalId":13862,"journal":{"name":"Intelligence","volume":"116 ","pages":"Article 102020"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147797996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reanalysis of the original data reveals that the asymmetry arises from the use of the conditional standard error of the correlation coefficient, which depends on the observed value of <em>r</em> and mechanically induces funnel-plot skew. When more appropriate methods, such as Fisher's <em>z</em>-transformation with unconditional standard errors, are applied, the asymmetry disappears and Egger's test becomes nonsignificant, <em>t</em>(238) = −1.41, <em>p</em> = .160. A complementary simulation study further confirms that conditional-error weighting can generate strong false signals of reversed publication bias and inflate total effect-size estimates even when no bias is present.

Yet global fit can coexist with weak evidence that item demands represent the target attribute. This article introduces Construct-Signature Validity (CSV), a design-based framework. Within the CSV framework, one source of evidence for construct validity is the degree to which pre-specified ability-by-complexity patterns are observed in test data. CSV treats intelligence as observable in person-by-task-demand patterns rather than only as a trait inferred from undifferentiated covariation. CSV outlines three nested signatures: a within-subtest signature (SCI), indexed by ordered correlations among low-, medium-, and high-complexity band scores across ability levels; a within-domain signature (DCI), indexed by a shift of the peak cross-subtest coherence to the complexity level matching group ability; and an item-level signature (ICI), indexed by ordered success probabilities and drop-contrast conditions across complexity bands. CSV is demonstrated with a secondary analysis of norming data from the Anadolu-Sak Intelligence Scale (ASIS). Items from four nonverbal subtests were classified a priori into three complexity levels, and children were divided into three IQ groups. SCI matched the predicted order at both low- and high-ability bands. However, the evidence was partial because the adjacent correlations were close and the key differences were small. The medium band showed adjacency without the predicted transition. DCI supported the expected peak shift in the high-ability group, but only partially in the low-ability group, and was absent in the medium-ability group. At the item level, percent-correct profiles and a binomial GEE model showed a reliable ability-by-complexity interaction. CSV complements factor models by providing testable evidence about where construct representation and calibration hold or fail across the ability distribution.</div></div>","PeriodicalId":13862,"journal":{"name":"Intelligence","volume":"116 ","pages":"Article 102022"},"PeriodicalIF":2.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147849608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
