Incubation (psychology)

Last updated

In psychology, incubation refers to the unconscious processing of problems, when they are set aside for a period of time, that may lead to insights. It was originally proposed by Graham Wallas in 1926 as one of his four stages of the creative process: preparation, incubation, illumination, and verification. [1] Incubation is related to intuition and insight in that it is the unconscious part of a process whereby an intuition may become validated as an insight. Incubation substantially increases the odds of solving a problem, and benefits from long incubation periods with low cognitive workloads. [2]

The experience of leaving a problem for a period of time and then finding that the difficulty evaporates on returning to the problem, or, even more striking, that the solution "comes out of the blue" when thinking about something else, is widespread. Many guides to effective thinking and problem solving advise the reader to set problems aside for a time.

Paradigm for investigation

The most widely adopted paradigm for investigating incubation involves comparing problems on which participants take a break during solving with problems on which participants work for a continuous period. The total time spent on each problem is equated across the conditions, and the incubation period is usually filled with unrelated activity to prevent further conscious work on the problem. Superior performance on problems for which work is split over two sessions is taken as evidence for the incubation effect, which is thus operationally defined as any benefit of a break during problem solving.

Effects of emotion and sleep

When discussing the relation between incubation effect, emotions, and creativity, researchers found that positive mood enhances creativity at work. That means that a given day's creativity would be expected to follow reliably from the previous day's mood, above and beyond any carry-over of that previous day's mood. Theory and research on incubation, long recognized as a part of the creative process, suggest such cross-day effects. Thus, if positive mood on a particular day increases the number and scope of available thoughts, those additional thoughts may incubate overnight, increasing the probability of creative thoughts the following day. [3]

Recent advances in neuroscience provide intriguing evidence of the mechanisms underlying incubation effects, particularly those that occur during sleep. This research reveals that people's experiences while awake can be consolidated into memory and result in enhanced performance the next day without any additional practice or engagement in the task. Moreover, there is mounting evidence that sleep can facilitate the types of memory and learning processes, such as associative memory, that contribute to creative problem solving. In one relevant experiment, researchers demonstrated that problem-solving insight can be dramatically enhanced by a period of sleep following initial work on a problem.[ citation needed ]

Effects of dreams

In the 1970s, Stanford Sleep Lab Director William Dement gave 500 undergraduate students three "brain-teaser" problems to read over before going to sleep and had them note whether they had solutions in their dreams that night; seven students had a dream containing the solution.[ citation needed ] In 1993, Harvard psychologist Deirdre Barrett conducted research asking college students to incubate answers to real-life homework and other objective problems on which they were working, finding that, in one week's time, half had dreamed about their topic and a quarter had a dream which provided an answer. [4] Barrett also interviewed modern artists and scientists about their use of their dreams, documenting dramatic anecdotes including winners of Nobel Prizes and MacArthur "Genius Grants" whose ideas originated in dreams. [5] Her research concludes that, while anything—math, musical composition, business dilemmas—may get solved during dreaming, the two areas dreams are especially likely to help are 1) anything where vivid visualization contributes to the solution, whether in artistic design or invention of 3-D technological devices and 2) any problem where the solution lies in thinking outside the box i.e. where the person is stuck because the conventional wisdom on how to approach the problem is wrong.

Not everybody agrees about the usefulness of dreams in solving problems. In the August 2004 article "Dreams: The Case Against Problem-Solving", G. William Domhoff concluded:

When all is said and done, there is only occasional anecdotal evidence for the idea that recalled dreams have any role in solving or detecting problems. This evidence is not impressive when it is arrayed against the small percentage of dreams that are recalled and the even smaller percentage of recalled dreams that might be construed as having a solution to a problem. Dreams may on occasion be useful to waking consciousness as a basis for thinking about problems in a new way, or as a basis for discussing personal problems, as some clinical research shows (Fiss, 1991; Greenberg et al., 1992). And dreams that have a dramatic emotional impact create a strong subjective sense that they must have a useful message. However, it does not follow from clinical usefulness or a waking impression of importance that dreaming has an adaptive function (Antrobus, 1993). [6]

Creativity Forming something new and somehow valuable

Creativity is a phenomenon whereby something new and valuable is formed. The created item may be intangible or a physical object.

Daydream Aspect of human thought and consciousness

Daydreaming is the stream of consciousness that detaches from current, external tasks when attention drifts to a more personal and internal direction. This phenomenon is common in people's daily life shown by a large-scale study in which participants spend 47% of their waking time on average on daydreaming. There are various names of this phenomenon including mind wandering, fantasy, spontaneous thoughts, etc. Daydreaming is the term used by Jerome L. Singer whose research programs laid the foundation for nearly all the subsequent research in this area today. The list of terminologies assigned by researchers today puts challenges on identifying the common features of the phenomenon, in this case daydreaming, and on building collective work among researchers.

Hypnagogia is the experience of the transitional state from wakefulness to sleep: the hypnagogic state of consciousness, during the onset of sleep. Its opposite state is described as hypnopompic — the transitional state from sleep into wakefulness. Mental phenomena that may occur during this "threshold consciousness" phase include hypnagogic hallucinations, lucid thought, lucid dreaming, and sleep paralysis. The latter two phenomena are themselves separate sleep conditions that are sometimes experienced during the hypnagogic state.

Creativity techniques are methods that encourage creative actions, whether in the arts or sciences. They focus on a variety of aspects of creativity, including techniques for idea generation and divergent thinking, methods of re-framing problems, changes in the affective environment and so on. They can be used as part of problem solving, artistic expression, or therapy.

Insight is the understanding of a specific cause and effect within a particular context. The term insight can have several related meanings:

Problem solving Approaches to problem solving

Problem solving consists of using generic or ad hoc methods in an orderly manner to find solutions to difficulties.

Dream incubation is a thought technique which aims for a specific dream topic to occur, either for recreation or to attempt to solve a problem. For example, a person might go to bed repeating to themselves that they will dream about a presentation they have coming up, or a vacation they recently took. While somewhat similar to lucid dreaming, dream incubation is simply focusing attention on a specific issue when going to sleep.

Insight is a sudden understanding of a problem or a strategy that aids in solving a problem. Usually, this involves conceptualizing the problem in a completely new way. Although insights may appear to be sudden, they are actually the result of prior thought and effort. While insight can be involved in solving well-structured problems, it is more often associated with ill-structured problems.

Outline of thought Overview of and topical guide to thought

The following outline is provided as an overview of and topical guide to thought (thinking):

Divergent thinking A method of generating creative ideas

Divergent thinking is a thought process or method used to generate creative ideas by exploring many possible solutions. It typically occurs in a spontaneous, free-flowing, "non-linear" manner, such that many ideas are generated in an emergent cognitive fashion. Many possible solutions are explored in a short amount of time, and unexpected connections are drawn. Following divergent thinking, ideas and information are organized and structured using convergent thinking, which follows a particular set of logical steps to arrive at one solution, which in some cases is a "correct" solution.

Sleep and creativity

The majority of studies on sleep creativity have shown that sleep can facilitate insightful behavior and flexible reasoning, and there are several hypotheses about the creative function of dreams. On the other hand, a few recent studies have supported a theory of creative insomnia, in which creativity is significantly correlated with sleep disturbance.

Eureka effect Human experience of suddenly understanding a previously incomprehensible problem or concept

The eureka effect refers to the common human experience of suddenly understanding a previously incomprehensible problem or concept. Some research describes the Aha! effect as a memory advantage, but conflicting results exist as to where exactly it occurs in the brain, and it is difficult to predict under what circumstances one can predict an Aha! moment.

Convergent thinking is a term coined by Joy Paul Guilford as the opposite of divergent thinking. It generally means the ability to give the "correct" answer to standard questions that do not require significant creativity, for instance in most tasks in school and on standardized multiple-choice tests for intelligence.

Systems-oriented design (S.O.D.) uses system thinking in order to capture the complexity of systems addressed in design practice. The main mission of S.O.D. is to build the designers' own interpretation and implementation of systems thinking. S.O.D. aims at enabling systems thinking to fully benefit from design thinking and practice, and design thinking and practice to fully benefit from systems thinking. S.O.D. addresses design for human activity systems, and can be applied to any kind of design problem ranging from product design and interaction design, through architecture to decision making processes and policy design.

The Remote Associates Test (RAT) is a creativity test used to determine a human's creative potential. The test typically lasts forty minutes and consists of thirty to forty questions each of which consists of three common stimulus words that appear to be unrelated. The person being tested must think of a fourth word that is somehow related to each of the first three words. Scores are calculated based on the number of correct questions.

The neurocircuitry that underlies executive function processes and emotional and motivational processes are known to be distinct in the brain. However, there are brain regions that show overlap in function between the two cognitive systems. Brain regions that exist in both systems are interesting mainly for studies on how one system affects the other. Examples of such cross-modal functions are emotional regulation strategies such as emotional suppression and emotional reappraisal, the effect of mood on cognitive tasks, and the effect of emotional stimulation of cognitive tasks.

<i>The Committee of Sleep</i>

The Committee of Sleep: How Artists, Scientists, and Athletes Use Dreams for Creative Problem-Solving—and How You Can Too is a book by Deirdre Barrett published by Crown/Random House in 2001. Barrett is a psychologist on the faculty of Harvard Medical School. The book describes how dreams have contributed practical breakthroughs to arts and sciences in the waking world. Chapters are organized by discipline: art, literature, science, sports, medicine, etc. There are long examples of dreams which led to major achievements in each area, but Barrett then draws conclusions about how dreams go about solving problems, what types they are best at, and gives advice on how readers can apply these techniques to their own endeavors. Those who are described in The Committee of Sleep as having dreamed creations include Ludwig van Beethoven, Billy Joel, Robert Louis Stevenson, Stephen King, Salvador Dalí, William Blake, and Nobel prize winner Otto Loewi.
