Creativity is a fundamental human trait, often defined by two criteria: originality (novelty) and appropriateness (relevance or usefulness), with surprise and quality sometimes added. The balance between originality and appropriateness can depend on the domain, such as art versus science/technology. The paper of creativity brings together various psychological disciplines, including cognitive, social, personality, developmental, organizational, clinical, and neuroscience, as well as computational modeling and evolutionary perspectives.
Researchers differentiate between personal creativity (new to the individual, sometimes called Little C or everyday creativity) and historical creativity (new to humanity, Big C or eminent creativity), recognizing that everyone possesses some degree of creativity. Mini C creativity involves making novel and personally meaningful interpretations. Creativity is related to, but distinct from, discovery (finding what already exists) and invention (creating something useful but impersonal); creativity is often seen as requiring a personal component. The relationship between creativity and intelligence is complex, with early research suggesting a threshold effect, while recent work indicates a more intricate connection. Unlike individual learning, which acquires pre-existing information, creativity involves generating new information through abstract thought and reprocessing internal mental content.
Historically, creativity was sometimes attributed to divine inspiration. Later psychological views included Freud's notion of the preconscious as a source. Wallas's classic four-stage model—preparation (gathering knowledge and focused work), incubation (unconscious processing), illumination (sudden insight), and verification (refining and presenting)—remains influential, though modern adaptations include problem finding/posing/construction and a potential frustration phase before incubation.
Cognitive approaches focus on processes like concept combination, expansion, imagery, and metaphor. Debates exist regarding the relative importance of expertise (like the "10-year rule"), chance, and intuition. While expertise provides necessary knowledge and skills, it can also lead to functional fixedness. Intuition is linked to the associative structure of memory, where creative individuals may have "flat associative hierarchies" providing better access to remote associations.
Creative thinking has been modeled as heuristic search, initially in a fixed state space and later involving the transformation or search for new state spaces through restructuring. Restructuring involves forming new concept combinations and viewing old concepts in new contexts, often through iterative and recursive processes. A more recent view suggests that creative thought involves honing a single, initially ill-defined mental representation that can manifest in different ways, akin to different shadows cast by one object, rather than selecting from multiple discrete ideas. This honing process is linked to the development of an individual's worldview, which is central to cultural evolution. The cognitive shift between generating new ideas and refining them is often conceptualized as moving between divergent thinking (exploring possibilities, reflecting from unconventional perspectives, associated with defocused attention) and convergent thinking (selecting/refining ideas, reflecting from conventional perspectives, associated with focused attention).
The debate on whether creativity is domain-specific or domain-general continues. Arguments for domain specificity rest on expertise requirements and distinct categories of creative achievement. Arguments for domain generality highlight cross-domain connections, associative thinking, metaphor, and the idea that creative processes or an individual's unique style can manifest across different domains. A contemporary view often acknowledges both aspects.
Individual differences are crucial in creativity research. Case studies and clinical approaches, while having limitations, offer insights. Mixed evidence exists regarding a link between creativity and affective disorders. Clinical applications utilize creative therapies (art, music, dance) for therapeutic effects. Developmental research highlights the importance of affect-laden thought, play, and fantasy in childhood creativity. Personality traits correlated with creativity include openness to experience, tolerance of ambiguity, impulsivity, self-confidence, energy, attraction to complexity, problem sensitivity, flexibility, and strong analytical/synthesis skills. Societal dynamics may balance creative and less creative individuals.
Creativity can be measured using psychometric tests like the Torrance Tests of Creative Thinking (assessing divergent thinking with tasks like Unusual Uses or Product Improvement), though these are criticized for not capturing the iterative process of Big C creativity. The Consensual Assessment Technique, where experts rate creative products, is considered superior for evaluating outputs. Case studies and techniques like brainstorming are also used.
Environmental factors significantly impact creativity, including education, mentors, family dynamics, group dynamics, and culture. Supportive environments free of immediate evaluation are often seen as beneficial, though research findings are complex. The systems approach views creativity as an interaction between the individual, the "field" (relevant people in the domain), and the "domain" (relevant ideas).
Neuroscientific research using EEG and fMRI suggests that creativity is associated with a loosening of cognitive control and decreased arousal, potentially involving lower levels of noradrenaline and dopamine. Divergent thinking may correlate with decreased beta and increased alpha synchrony over the frontal cortex. Creative thought involves the interplay of networks like the default network (spontaneous thought) and executive control networks. At a neural level, creativity may be facilitated by the distributed, content-addressable nature of memory, allowing task-relevant items to come to mind without systematic search. Creative interference, where simultaneously evoked, overlapping neural distributions result in new, initially vague ideas, may also play a role. High functional connectivity between default, salience, and executive networks is observed in creative individuals.
Evolutionary approaches explore how humans developed enhanced creative abilities, potentially linked to brain size increases and the capacity to shift between cognitive modes. Computational modeling helps test hypotheses about these evolutionary transitions and simulate the evolution of ideas within societies.
Computational creativity aims to build systems that generate creative outputs. Early efforts included programs like BACON for discovering scientific laws. Modern approaches use machine learning, deep learning, and evolutionary computation to create music, art, and linguistic forms, some achieving human-like results. Computational models also simulate creative processes like shifting cognitive modes, incubation, and insight.
The psychological paper of creativity has practical implications for clinical therapy, education (fostering creativity, teaching methods, providing free time, considering intrinsic motivation), and business (brainstorming techniques, organizational strategies). Understanding creativity is increasingly vital in times of rapid change, demanding novel solutions and perspectives. Future research directions include further computational modeling, exploring the biological basis, and tracking specific creative ideation processes over time.
