Using a joint hierarchical model of responses and response times, results indicated good model fit across subtests, with weak correlations between examinee ability and examinee tempo for verbal tasks (<em>r</em> = −0.208 to 0.317) and stronger negative correlations for visuospatial tasks (<em>r</em> = −0.504 to −0.774), supporting predictions from dual process theory. Item intensity positively correlated with response times with difficulty on most subtests, indicating that item characteristics were the cause of longer response times for more difficult items. Few examinees (2.5 %) exhibited dual misfit in responses and times, but the Figure Weights subtest revealed anomalous slow responding.

Both maternal and paternal education and occupational status significantly predicted children's GIQ beyond demographic covariates, with parental education showing stronger associations than occupational status. The results also showed partial mediation in both directions: parental education partly explained the link between occupational status and GIQ, and occupational status partly explained the link between parental education and GIQ, especially for mothers. Evidence that education and occupation changed each other's effects was limited and small in size.

In a 2 × 2 MANOVA and subsequent ANOVAs with the four scales of the multi-dimensional questionnaire (economic libertarianism, liberalism, conservatism, socialism), no significant main or interaction effect emerged, except a significant interaction effect of giftedness and sex for conservatism. Specifically, non-gifted men showed higher conservatism scores than gifted men, whereas gifted and non-gifted women did not differ significantly.

Although individuals with this condition experience various challenges and require support in different areas of life, research on this topic remains limited. Therefore, this article presents a systematic review aimed at describing the cognitive profile of individuals with BIF. The review included studies addressing the intellectual functioning of the BIF population published between 2012 and 2024. The literature search was conducted in the ProQuest, WoS, SCOPUS, and EBSCOhost databases. Finally, a total of 33 articles were included, and their quality was assessed using the SSAHS tool. The results were organised into three categories: general cognitive abilities, executive functions, language cognition, and neurophysiology. The analysis indicates that individuals with BIF exhibit a cognitive profile characterised by deficits in various domains, including executive functions (such as working memory, cognitive flexibility, processing speed, and planning), general cognitive abilities (such as memory, attention, abstract thinking, problem-solving, arithmetic, and concentration), and language-related cognitive skills, both oral and written. Additionally, neuroimaging techniques suggest that BIF is also associated with structural and functional alterations in the brain. The implications and limitations of the study are discussed, as well as the need for future research with larger samples and more comprehensive assessments.
