The establishment of a moderate, positive correlation between face processing and intelligence would suggest it may be integrated within the Cattell-Horn-Carroll model of intelligence. Additionally, developmental prosopagnosia<span>, a specific impairment of the recognition of facial identity, may be assessable in a manner similar to a learning disability. Consequently, we employed a psychometric meta-analytic approach to estimate the true score correlation between intelligence and face processing ability. Intelligence was positively and significantly correlated with face detection (</span></span><em>r’</em> = 0.20; <em>k</em> = 2, <em>N =</em> 407), face perception (<em>r’</em> = 0.42, <em>k</em> = 11, <em>N</em> = 2528), and face memory (<em>r’</em> = 0.26, <em>k</em> = 23, <em>N</em> = 9062). Additionally, intelligence measurement quality moderated positively and significantly the association between intelligence and face memory (<em>β</em> = 0.08). On the basis of both theoretical and empirical considerations, we interpreted the results to suggest that face processing ability may be plausibly conceptualised within the Cattell-Horn-Carroll model of intelligence, in a manner similar to other relatively narrow dimensions of cognitive ability, i.e., associated positively with intelligence, but also distinct (e.g., reading comprehension). Potential clinical implications for the assessment of developmental prosopagnosia are also discussed.</p></div>","PeriodicalId":13862,"journal":{"name":"Intelligence","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41529653","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}

Because of between-study design differences and data availability in terms of differing IQ domains, it is so far unclear if these inconsistencies represent a consequence of differences in Flynn effect trajectories between countries, covered time-spans, or investigated IQ domains. Here, we present data from 36 largely population-representative Germanophone standardization samples from 12 well-established psychometric tests (17 subtests) of 10 stratum II domains from 1996 to 2018, thus providing a comprehensive assessment of domain-specific changes according to the Cattell-Horn-Carroll intelligence model. Examination of both raw score and measurement-invariant latent mean changes yielded positive (comprehension-knowledge, learning-efficiency, domain-specific knowledge), negative (working memory capacity), stagnating (processing speed, reading and writing), and ambiguous (fluid reasoning, reaction and decision speed, quantitative knowledge, visual processing) stratum II Flynn effects. This means that in the present sample, the Flynn effect is surprisingly differentiated on domain level and does not conform to the frequently observed IQ test score gains in crystallized and fluid intelligence. These findings could be attributed to either (i) a so far undetected domain-specificity of the Flynn effect due to an unavailability of test data beyond crystallized and fluid domains or (ii) a symptom for an impending stagnation of the Flynn effect.</p></div>","PeriodicalId":13862,"journal":{"name":"Intelligence","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0160289622000885/pdfft?md5=7f677bc4a2a78cdd0c89710394f12571&pid=1-s2.0-S0160289622000885-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48769455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These environmental improvements may have caused Flynn effect-like cognitive changes to occur in these populations, perhaps if these improvements enhanced cognitive plasticity and, consequently, learning potential. While lack of relevant data precludes cross-temporal comparison of cognitive performance means of laboratory rodent populations, it is possible to estimate changes in the proportion of cognitive performance variance attributable to general cognitive ability (GCA) over time. This “differentiation effect” has been found to occur along with the Flynn effect in human populations, suggesting that environmental factors, possibly mediated by their effects on life history speed, may weaken the manifold of GCA across time, allowing for greater cultivation of specialized abilities. Meta-analysis of the literature on mouse and rat cognition yielded 25 mouse studies from which 28 GCA effect sizes could be estimated, and 10 rat studies from which 11 effect sizes could be estimated. Cross-temporal meta-analysis yielded evidence of significant “differentiation effects” spanning approximately a century in both mice and rats, which were independent of age, sex, factor estimation technique, and task number in the case of the mice, and both factor estimation technique and task number in the case of the rats. These trends were also independent of the random effect of strain in both cases. While this is suggestive of the presence of the Flynn effect in captive populations of non-human animals, there are still factors that might be confounding these results.
