Cognitive skill in the context of "Decision making"

Intellect is a faculty of the human mind that enables reasoning, abstraction, conceptualization, and judgment. It enables the discernment of truth and falsehood, as well as higher-order thinking beyond immediate perception. Intellect is distinct from intelligence, which refers to the general ability to learn, adapt, and solve problems, whereas intellect concerns the application of reason to abstract or philosophical thought.

In philosophy, intellect (Ancient Greek: dianoia) has often been contrasted with nous, a term referring to the faculty of direct intuitive knowledge. While intellect engages in discursive reasoning, breaking down concepts into logical sequences, nous is considered a higher cognitive faculty that allows for direct perception of truth, especially in Platonism and Neoplatonism. Aristotle distinguished between the active intellect (intellectus agens), which abstracts universal concepts, and the passive intellect, which receives sensory input.

The g factor is a construct developed in psychometric investigations of cognitive abilities and human intelligence. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The g factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores ("IQ scores") based on many tests are frequently regarded as estimates of individuals' standing on the g factor. The terms IQ, general intelligence, general cognitive ability, general mental ability, and simply intelligence are often used interchangeably to refer to this common core shared by cognitive tests. However, the g factor itself is a mathematical construct indicating the level of observed correlation between cognitive tasks. The measured value of this construct depends on the cognitive tasks that are used, and little is known about the underlying causes of the observed correlations.

The existence of the g factor was originally proposed by the English psychologist Charles Spearman in the early years of the 20th century. He observed that children's performance ratings, across seemingly unrelated school subjects, were positively correlated, and reasoned that these correlations reflected the influence of an underlying general mental ability that entered into performance on all kinds of mental tests. Spearman suggested that all mental performance could be conceptualized in terms of a single general ability factor, which he labeled g, and many narrow task-specific ability factors. Soon after Spearman proposed the existence of g, it was challenged by Godfrey Thomson, who presented evidence that such intercorrelations among test results could arise even if no g-factor existed.

Nous (UK: /naʊs/, US: /nuːs/), from Ancient Greek: νοῦς, is a concept from classical philosophy, sometimes equated to intellect or intelligence, for the faculty of the human mind necessary for understanding what is true or real.

Alternative English terms used in philosophy include "understanding" and "mind"; or sometimes "thought" or "reason" (in the sense of that which reasons, not the activity of reasoning). It is also often described as something equivalent to perception except that it works within the mind ("the mind's eye"). It has been suggested that the basic meaning is something like "awareness". In colloquial British English, nous also denotes "good sense", which is close to one everyday meaning it had in Ancient Greece. The nous performed a role comparable to the modern concept of intuition.

The language module or language faculty is a hypothetical structure in the human brain which is thought to contain innate capacities for language, originally posited by Noam Chomsky. There is ongoing research into brain modularity in the fields of cognitive science and neuroscience, although the current idea is much weaker than what was proposed by Chomsky and Jerry Fodor in the 1980s. In today's terminology, 'modularity' refers to specialisation: language processing is specialised in the brain to the extent that it occurs partially in different areas than other types of information processing such as visual input. The current view is, then, that language is neither compartmentalised nor based on general principles of processing (as proposed by George Lakoff). It is modular to the extent that it constitutes a specific cognitive skill or area in cognition.

Mindfulness is the cognitive skill, usually developed through exercises, of sustaining metacognitive awareness towards the contents of one's own mind and bodily sensations in the present moment. The term mindfulness derives from the Pali word sati, a significant element of Buddhist traditions, and the practice is based on ānāpānasati, Chan, and Tibetan meditation techniques.

Since the 1990s, secular mindfulness has gained popularity in the West. Individuals who have contributed to the popularity of secular mindfulness in the modern Western context include Jon Kabat-Zinn and Thích Nhất Hạnh.

Extraterrestrial intelligence (ETI) refers to hypothetical extraterrestrial life having the intelligence to perform similar cognitive abilities as humans. No such life has ever been verifiably observed to exist. The question of whether other inhabited worlds might exist has been debated since ancient history. The modern form of the concept emerged when the Copernican Revolution demonstrated that the Earth was a planet revolving around the Sun, and other planets were, conversely, other worlds. The question of whether other inhabited planets or moons exist was a natural consequence of this new understanding. It has become one of the most speculative questions in science and is a central theme of both science fiction and popular culture.

An alternative name for it is "Extraterrestrial Technological Instantiations" (ETI). The term was coined to avoid the use of terms such as "civilizations", "species", and "intelligence", as those may prove to be ambiguous and open to interpretation, or simply inapplicable in its local context.

Cetacean intelligence is the overall intelligence and derived cognitive ability of aquatic mammals belonging in the infraorder Cetacea (cetaceans), including baleen whales, porpoises, and dolphins. In 2014, a study found that the long-finned pilot whale has more neocortical neurons than any other mammal, including humans, examined to date.

A brain–computer interface (BCI), sometimes called a brain–machine interface (BMI), is a direct communication link between the brain's electrical activity and an external device, most commonly a computer or robotic limb. BCIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions. They are often conceptualized as a human–machine interface that skips the intermediary of moving body parts (e.g. hands or feet). BCI implementations range from non-invasive (EEG, MEG, MRI) and partially invasive (ECoG and endovascular) to invasive (microelectrode array), based on how physically close electrodes are to brain tissue.

Research on BCIs began in the 1970s by Jacques Vidal at the University of California, Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from the Defense Advanced Research Projects Agency (DARPA). Vidal's 1973 paper introduced the expression brain–computer interface into scientific literature.
