hot cognition
Hot and cold cognition form a dichotomy within executive functioning. Executive functioning has long been considered as a domain general cognitive function, but there has been support for separation into "hot" affective aspects and "cold" cognitive aspects. It is recognized that executive functioning spans across a number of cognitive tasks including working memory, cognitive flexibility and reasoning in active goal pursuit. The distinction between hot and cool cognition implies that executive function may operate differently in different contexts. Hot and cold cognition have been applied to research in cognitive psychology, developmental psychology, clinical psychology, social psychology, neuropsychology, and other areas of study in psychology.
Hot cognition is a hypothesis on motivated reasoning in which a person's thinking is influenced by their emotional state. Put simply, hot cognition is cognition coloured by emotion. It is proposed to be associated with cognitive and physiological arousal, in which a person is more responsive to environmental factors. As it is automatic, rapid and led by emotion, hot cognition may consequently cause biased and low-quality decision making. Hot cognition may arise, with varying degrees of strength, in politics, religion, and other sociopolitical contexts because of moral issues, which are inevitably tied to emotion. Hot cognition was initially proposed in 1963 by Robert P. Abelson. This idea became popular in the 1960s and the 1970s. An example of a biased decision caused by hot cognition would be a juror disregarding evidence because of an attraction to the defendant.
==Development and neuroanatomy==
Performance on hot and cold tasks improves most rapidly during the preschool years,〔 but continues into adolescence. This co-occurs with both structural and functional development associated with the prefrontal cortex. Specific areas within the PFC are thought to be associated with both hot and cold cognition. Hot cognition is likely to be utilized during tasks that require the regulation of emotion or motivation, as well as reevaluating the motivational significance of a stimulus. The ventral and medial areas of the prefrontal cortex (VM-PFC) are implicated during these tasks. Cold cognition is thought to be associated with executive functions elicited by abstract, deconceptualized tasks, such as card sorting. The area of the brain that is utilized for these tasks is the dorsolateral prefrontal cortex (DL-PFC). It is between the ages of 3 years and 5 years that the most significant change in task completion is seen.〔 Age-related trends have been observed in tasks used to measure hot cognition, as well as cold cognition.〔 However, the age at which children reach adult-like functioning varies. It appears as though children take longer to fully develop hot executive functioning than cold. This lends support to the idea that hot cognition may follow a separate, and perhaps delayed, developmental trajectory as opposed to cold cognition. Further research done on these neurological areas suggests there may be some plasticity during the development of both hot and cold cognition. While the preschool years are ones of extreme sensitivity to the development of prefrontal cortex, a similar period is found in the transition into adolescence.〔 This gives rise to the idea that there may be a possible time window for intervention training, which would improve cognitive abilities and executive functioning in children and adolescents.
