Gf positively correlated with the delta band power, while there was no correlation with the theta band power. For almost all of the participants, we identified the specific slow rhythm frequency, which varied in power as a function of item difficulty. We observed that the lower this frequency, the higher Gf, but only in men. Finally, the alpha and low-beta activity correlated negatively with Gf after we had filtered out the activity during idle intervals (the latter reflecting waiting for the response bank).

Here, we present evidence for sex differences in international large-scale assessments of reading literacy, mathematics, and science across 16 cohorts from 1995 to 2019. Our analyses of PIRLS and TIMSS reading literacy, mathematics, and science achievement data (<em>N</em> = 3,999,062; 90 countries) showed consistent advantages for girls in reading literacy (<em>d</em> range: −0.02 to 0.66). For mathematics and science this pattern was less unambiguous, yielding non-trivial effects in both directions (<em>d</em> ranges: −0.44 to 0.36 and − 0.50 to 0.46, respectively). Sex differences in all three domains were more pronounced in more egalitarian countries (β range 0.16 to 0.20). Higher national prosperity and educational investment predicted larger sex differences favoring fourth grade boys in mathematics and science (β range: 0.07 to 0.39) and became less meaningful with increasing student ages (β range for eighth graders: 0.17 to 0.21). In all, our findings suggest that influences of economic macro-indicators on sex differences in educational achievement are differentiated according to subject, indicating larger sex differences in mathematics and science in more egalitarian and prosperous countries.</p></div>","PeriodicalId":13862,"journal":{"name":"Intelligence","volume":"100 ","pages":"Article 101784"},"PeriodicalIF":3.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45079533","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}

By investigating the relationship between learning ability and CPS, while accounting for interactions between complex system characteristics and person characteristics, this paper aims to understand the role of learning processes in CPS more closely. In a sample of <em>N</em> = 241 participants, we performed a preregistered analysis to investigate the relationship between knowledge acquisition performance in a CPS test (MicroDYN) and learning test performance (ADAFI) with a multilevel modeling approach across 10 CPS systems with various characteristics. In line with our expectations, we replicated previous findings on a relationship between learning test and MicroDYN performance and found this relationship to be more pronounced in systems with (vs. without) autonomous changes. Further system and person characteristics also showed effects as expected, with better performance in systems with lower complexity, with more experience with the task, and with more strategic exploration behaviour. Our results provide further evidence for the notion that learning is an important component for the successful completion of CPS tasks.</p></div>","PeriodicalId":13862,"journal":{"name":"Intelligence","volume":"100 ","pages":"Article 101773"},"PeriodicalIF":3.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48499776","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}

By jointly analyzing item responses and eye-tracking measures, this model can measure each participant's intelligence and identify the cognitive strategy used by each participant for each item in the APM. Several main findings were revealed from an eye-tracking-based APM study using the proposed model: (1) The effects of PTM and RLT on the constructive matching strategy selection probability were positive and higher for the former than the latter, while the effect of ROT was negligible. (2) The average intelligence of participants who used the constructive matching strategy was higher than that of participants who used the response elimination strategy, and participants with higher intelligence were more likely to use the constructive matching strategy. (3) High-intelligence participants increased their use of the constructive matching strategy as item difficulty increased, whereas low-intelligence participants decreased their use as item difficulty increased.

Tilt was based on within subject differences in technical (mechanical, electrical, automotive) and academic abilities (math or verbal) on the Armed Services Vocational Aptitude Battery. The differences produced tech tilt (technical &gt; academic) and academic tilt (academic &gt; technical). Consistent with investment theories and sex differences in technical preferences, males showed increases in tech tilt over time, whereas females showed increases in academic tilt over time, with sex differences in tilt increasing with age. In addition, processing speed and general intelligence (<em>g</em>) mediated most age-tilt relations, with age-tech tilt relations generally being stronger for males. The stronger age-tech tilt relations for males support investment theories and sex differences in vocational interests, which assume that stronger technical interests in males accelerate increases in tech tilt over time. The mediating effects of speed and <em>g</em> are consistent with cascade theories, which assume that age-related increases in speed boost <em>g</em>, which in turn boosts tilt.

We compared multivariate twin models built on scores from the five scales of the Mullen Scales of Early Learning (MSEL) in a community sample of monozygotic and dizygotic twins at 5 months of age (n=567). The results indicated a hierarchical etiological structure whereby a general genetic latent factor accounted for 54% of variance underlying the different domains of emerging cognitive and motor abilities (A=0.54, confidence interval CI=[0; 0.82]). We also found additional genetic influences that were specific to early motor and language development. Unlike previous findings on older children, we did not find significant influences of shared environment on the shared factor (C=0, CI=[0, 0.57]), or any specific scale. Furthermore, influences of unique environment, which include measurement error, were moderate and statistically significant (E=0.46, CI=0.18; 0.81]). This study provides strong evidence for a unitary hierarchical structure across different domains of emerging cognition.
