Cold-control theory is a metacognitive theory of hypnosis proposing that hypnotic responses involve intentional actions that are experienced as unintentional because the person inaccurately represents their own intentions. The account distinguishes the processes that produce a response from the processes through which a person becomes aware of having intended that response. It was formulated by psychologists Zoltán Dienes and Josef Perner in 2007.

Dienes and Perner introduced the theory in a chapter of Hypnosis and Conscious States: The Cognitive Neuroscience Perspective. Their argument addressed whether executive control—the regulation of behavior in accordance with goals—necessarily requires conscious awareness. Drawing on higher-order thought theories of consciousness, they proposed that executive processes could operate without the corresponding awareness of exercising control, and that hypnosis could provide an example.

The theory's name refers to control without an appropriate higher-order thought, commonly abbreviated HOT. "Cold" therefore concerns the proposed absence of accurate higher-order representation, rather than emotional detachment or a physiological cooling process.

Theoretical framework

Intention and awareness of intention

Cold-control theory draws on the distinction between a first-order mental state and a higher-order representation of that state. A first-order intention directs an action. A higher-order representation concerns the person's being in that intentional state. These are different representational functions, even when ordinarily experienced together.

For example, in a suggestion that an arm will rise by itself, the theory proposes that an ordinary motor intention produces the movement. What changes is the representation of that intention: the participant experiences the movement as occurring without having intended it. On this account, the response involves an inaccurate representation of authorship, not simply a failure to pay attention to the arm.

The proposal is therefore more specific than saying that hypnosis makes people unconscious or switches off executive control. The action remains intentional in the theory's technical sense, while the participant experiences it as involuntary. This is intended to explain genuine changes in experience, rather than merely outward compliance accompanied by an unchanged awareness of deliberately acting.

Physical and mental responses

The account applies to both bodily movements and mental actions. Dienes's 2012 formulation describes hypnotic responding as the intentional performance of a physical or mental action accompanied by an inaccurate representation that the action was not intended. The theory locates the distinctive feature of hypnosis in this metacognitive relationship, rather than in a special capacity available only during hypnosis.

A central prediction is that hypnosis should not, solely by changing awareness of intention, confer first-order abilities unavailable outside hypnosis. This does not predict that suggestions can never improve performance relative to a baseline. Rather, a suitably matched nonhypnotic strategy should be capable of producing the same first-order benefit, even when the two conditions differ in experienced control.

The theory also does not necessarily predict a general deficiency in metacognition among highly hypnotizable people. Its principal concern is awareness of intentions and authorship, rather than every form of self-assessment, such as confidence in memory or judgments of perceptual accuracy.

Empirical investigations

Awareness of intention

In a 2016 study, Peter Lush, Peter Naish, and Zoltán Dienes examined participants' retrospective reports of when they first became aware of intending to move. Using a Libet-style clock task, they found that more highly hypnotizable participants reported later awareness of intention than less hypnotizable participants. Mindfulness meditators reported earlier awareness than nonmeditators. Two further studies in the same publication supported the association between hypnotizability and later reported intention timing.

The authors interpreted these findings as consistent with differences in access to intention-related information. However, the measure concerns reported timing, not a direct observation of when an intention first existed. The relationship between such timing measures, conscious intention, and sense of agency remains methodologically contested.

Brain-stimulation studies

Dienes and Sam Hutton tested a neural prediction of the theory in a study published in 2013. Twenty-four moderately hypnotizable participants received low-frequency repetitive transcranial magnetic stimulation over the left dorsolateral prefrontal cortex and over a comparison site in counterbalanced sessions. The researchers reported increased combined behavioral and subjective responsiveness after left-prefrontal stimulation, without a corresponding difference in expected responsiveness. They interpreted the result as supporting accounts in which reduced prefrontal contributions to metacognition facilitate hypnotic responding.

Subsequent findings were not a straightforward replication. In 2018, Max Coltheart and colleagues reported no effect from repeating the left-sided stimulation procedure. A second experiment found increased objectively measured hypnotizability after right-sided stimulation. Those authors interpreted their findings through an account of belief evaluation and suspension of disbelief. The studies therefore provide differing results and theoretical interpretations, rather than establishing a unique neural mechanism for cold control.

Hypnotic suggestion and deliberate imagination

A 2021 experiment by Bence Palfi and colleagues compared a posthypnotic suggestion with a voluntary imagination instruction during a Stroop task. Participants were either suggested to experience written words as meaningless symbols or asked deliberately to imagine them that way. Both interventions reduced interference from the words. Bayesian analysis supported equivalent reductions in interference across the two conditions.

Participants nevertheless described the interventions differently: the voluntary condition involved more experienced control and imagination, whereas the suggestion condition was experienced more as a perceptual alteration. The authors interpreted this combination—similar performance but different subjective experience—as supporting the distinction between first-order abilities and metacognitive awareness proposed by cold-control theory.

Neuroscientific interpretation

Cold-control theory is principally a psychological account with implications for neuroscience. It does not by itself identify a single brain region whose activity establishes that a person is responding hypnotically. A 2024 review by Vilfredo De Pascalis discusses changes in executive-network integration as potentially relevant to altered agency, while noting that such findings can be interpreted through more than one theoretical account.

The same review emphasizes inconsistencies across neuroimaging and electrophysiological studies. Differences in induction procedures, suggestions, experimental tasks, and participant characteristics complicate attempts to identify a common neural mechanism. Findings that hypnosis changes brain activity are therefore not, on their own, confirmation of the specific claim that inaccurate awareness of intention explains hypnotic responding.

More generally, hypnosis research distinguishes between investigating the mechanisms of hypnosis itself and using suggestions to study particular perceptual, cognitive, or clinical phenomena. Demonstrating that a suggestion changes a perceptual experience does not automatically establish which theory explains the response.

Relationship to other accounts

Cold-control theory differs from dissociated-control theories, which propose that hypnotic responding involves a separation between executive control and the systems generating behavior. In cold control, executive intention is retained; the proposed alteration concerns awareness of that intention.

The theory is compatible with aspects of sociocognitive approaches emphasizing expectations, context, and goal-directed responding. Its distinctive contribution is the proposed metacognitive explanation of involuntariness. Consequently, it does not require treating social explanations and cognitive mechanisms as mutually exclusive alternatives.

Extension to phenomenological control

Dienes and colleagues have developed the related concept of phenomenological control: a capacity to generate experiences consistent with goals and expectations, including outside situations explicitly described as hypnosis. In a 2022 paper, they proposed cold control as a mechanism through which intentional cognitive and motor processes could occur without awareness of the relevant intentions.

The authors considered possible contributions to experiences studied in other experimental settings, including the rubber-hand illusion and vicarious pain. They explicitly described the extent of those contributions as uncertain. Phenomenological control is therefore a broader research proposal, not evidence that cold control has been established as the explanation of all such phenomena.

Criticism and unresolved questions

In their 2024 systematic review, Anoushiravan Zahedi, Steven Jay Lynn, and Werner Sommer questioned whether a single metacognitive mechanism adequately explains the diversity of hypnotic responses and differences among highly hypnotizable participants. They also identified difficulties concerning the relationship between behavioral responsiveness and reported involuntariness, interpretations of cognitive-performance experiments, and the proposed roles of prefrontal functions.

These objections concern the theory's explanatory scope and interpretation of evidence. The review's broader conclusion was that competing theories of hypnosis have different strengths and limitations, and that no consensus explanation accounts for the full range of findings. Cold-control theory accordingly remains a subject of empirical investigation and theoretical disagreement.
