Short answer "Perceptual competence" is "the ability to perceive". Background I Googled "perceptual competence" and the first hit was an open source article (Lencz et al., 2003). They define perceptual competence as: [The] initial representation of to-be-remembered material [in the context of working memory]. Perceptual competency itself can include ...

Short answer: Processing speed is linked to executive functioning (EF) ability as well as specific, individual abilities (verbal, spatial, etc.), whereas generalized inspection time (IT) and reaction time (RT) to simple stimuli is more representative of general intelligence. Detailed answer: There are several factors that go into intelligence. Three ...

In addition to MariaAnt's good contribution, let me take another angle. You wrote: Studies comparing identical and fraternal twins, or occasionally identical twins reared apart have mostly concluded that there is a pretty high heritability of IQ. These studies, in particular the identical twins reared apart studies, imply that someone with the same genes ...

There are several ways in which this apparent paradox can be resolved. As a starting point, it is important to consider how heritability is defined and assessed (also see this earlier answer). As you point out, heritability estimates originate from comparisons between people who differ in their genetic similarity (e.g., monozygotic vs. dizygotic twins). The ...

The length of your question and it's tags make it quite confusing, however what you mentioned about the brain processing tasks sequentially and then hitting an efficiency bottle-neck when using conflicting resources reminds me of the research of Neils Taatgen. He uses a cognitive model called ACT-R to do computer simulations to predict what efficiency ...
