How Pretense Shapes Brain and Cognitive Development

Pretense is the act of representing something as other than what it is, and it shows up across an extraordinarily wide range of human behavior. A toddler holding a banana to her ear and “talking on the phone” is engaging in pretense. So is an actor inhabiting a character on stage, a poker player concealing a strong hand, or a person faking an illness for personal gain. What unites all of these is a deliberate gap between what is real and what is presented. The concept cuts through developmental psychology, neuroscience, clinical medicine, and everyday social life in ways that make it far more interesting than any single definition can capture.

How Pretense Develops in Early Childhood

Children begin pretending earlier than most people expect. Simple pretend acts, like lifting an empty cup to the lips and making drinking sounds, tend to appear around 12 to 18 months. By around age two, pretend play becomes more elaborate: children start substituting one object for another (a stick becomes a sword) and inventing scenarios that go beyond simple imitation of daily routines. Researchers tracking younger siblings of children with autism found that by 22 months, typically developing toddlers already scored meaningfully on structured pretend-play tasks, and their performance continued to improve through 34 months.1PubMed Central. Developmental Changes in Pretend Play from 22- to 34-months in Younger Siblings of Children with Autism Spectrum Disorder

Between ages three and five, pretend play reaches its peak complexity. Children assign roles to themselves and others, negotiate storylines, create invisible props, and sustain imaginary scenarios over extended periods. This is the age when you’ll hear a child insist that the floor is lava or that the family dog is actually a dragon. What looks like silliness from the outside involves a surprising amount of cognitive work under the surface.

Why Pretending Is Cognitively Demanding

To pretend that a banana is a telephone, a child has to hold two things in mind at once: the banana is still a banana, and it is also temporarily functioning as a phone. That dual-representation skill draws on the same mental resources used in more “serious” cognitive tasks. Research with preschoolers has found that performance on pretend-play tasks correlates with executive function, the set of skills involved in impulse control, mental flexibility, and working memory. The connection makes intuitive sense: pretending requires inhibiting the literal identity of an object while flexibly treating it as something else.2PubMed Central. Evidence for a relation between executive function and pretense representation in preschool children

Pretense also shares cognitive architecture with counterfactual reasoning, which is the ability to think about how things could have gone differently. Both involve mentally constructing situations that don’t match reality. Cross-cultural work with children in the United States and Peru found that the ability to reason causally during pretend scenarios appears early and may support later development of more complex “what if” thinking about real events.3Philosophical Transactions of the Royal Society B. Causal learning, counterfactual reasoning and pretend play: a cross-cultural comparison of Peruvian, mixed- and low-socioeconomic status U.S. children The theoretical claim is that pretense and counterfactual reasoning rely on the same underlying cognitive mechanisms, though pinning down the exact nature of the relationship has proven tricky. One investigation found that while pretense and counterfactual reasoning are clearly associated, both also overlap with other cognitive abilities, making it hard to isolate a unique connection between the two.4University of Cambridge Repository. Pretence and Counterfactual Reasoning: What is the nature of the relationship

Pretend Play and Language

The link between pretend play and language development is one of the more consistent findings in the literature. During pretend scenarios, children practice using words in new ways, experiment with different speech registers (a child playing “teacher” talks differently from a child playing “baby”), and stretch their vocabulary to fit the demands of the fantasy. Reviews of this research highlight that pretend play connects with children’s semantic diversity, their ability to combine words creatively, and their use of context-appropriate speech acts.5Journal of Education. Pretend Play and Early Language Development—Relationships and Impacts: A Comprehensive Literature Review

The relationship runs in both directions, and timing seems to matter. One study that followed preschoolers over time found that a specific pretend-play task, pretending to talk on a toy telephone, predicted later receptive vocabulary scores. The researchers suggested that pretend play and language may share a common symbolic foundation, along with the social context that pretense naturally creates for practicing communication.6Cognitive Development. A multidimensional investigation of pretend play and language competence: Concurrent and longitudinal relations in preschoolers That makes sense when you think about it: pretend play, at its core, is about one thing standing for another, and so is language.

Understanding Other Minds

Pretense has a natural overlap with theory of mind, the ability to understand that other people have thoughts, beliefs, and intentions different from your own. When a child pretends to be a doctor treating a sick patient, she’s implicitly modeling another person’s perspective, motivations, and knowledge. Researchers have argued that pretend play implicates at least three skills that also underlie theory of mind: representing one object as two things at once, seeing one object as standing for another, and representing other people’s mental representations.7PubMed. Pretend play skills and the child’s theory of mind

This connection extends to children who create imaginary companions. Studies of children with imaginary friends found that these kids were more likely to describe their real-life best friends using mental characteristics, referring to what their friends think, feel, or want, rather than focusing only on physical traits or activities. Girls in the study also performed better on a theory-of-mind task than boys, regardless of whether they had an imaginary companion.8PubMed Central. Children with Imaginary Companions Focus on Mental Characteristics When Describing Their Real-Life Friends The takeaway isn’t that imaginary friends make children smarter. It’s that children who are drawn to creating rich imaginary social worlds tend to be practicing the same skills they’ll need for real social understanding.

What the Brain Does During Pretense

Neuroimaging research has started to map what happens in the brain when people watch or engage in pretend acts. When adults observed someone using an object in a pretend way (treating a cup as if it were a hat, for example), brain regions associated with thinking about other people’s mental states lit up. These included the medial prefrontal cortex, parts of the lateral prefrontal cortex, the temporal poles, and the right superior temporal sulcus, a region heavily involved in social perception.9Social Cognitive and Affective Neuroscience. Neural correlates of observing pretend play in which one object is represented as another In other words, simply recognizing that someone else is pretending recruits the brain’s social cognition network.

Research on professional actors brings an additional wrinkle. When actors performed as a character rather than responding as themselves, researchers found deactivations in areas of the medial prefrontal cortex that are typically active during self-referential thinking. At the same time, regions associated with theory of mind, including the posterior superior temporal sulcus and the temporo-parietal junction, became more active. The finding suggests that deep pretense involves a kind of temporary self-suppression: the actor’s own identity is turned down so that the character’s perspective can be turned up.10PubMed Central.

Pretense and Autism

Reduced spontaneous pretend play is one of the earliest and most consistent behavioral markers associated with autism. When left to play freely, children with autism tend to initiate much less pretend play than typically developing peers. The transition from functional play (using objects for their intended purpose) to symbolic play (using objects to represent something else) appears to be a particular stumbling block, even when these children show functional play abilities that exceed what their overall developmental level would predict.11PubMed Central. Pretending to Play or Playing to Pretend: The Case of Autism

The picture gets more complicated, though, when researchers provide structure. When given prompts and demonstrations, children with autism sometimes perform pretend acts at levels matching typically developing peers at the same developmental stage. But whether they are truly pretending, or instead using logic to figure out what the “expected” behavior is without engaging the mental state of pretense, remains debated. Some researchers have described these performances as “expected pretend acts,” suggesting that the outward behavior of pretense can be mimicked through different cognitive routes.12PubMed Central. Pretending to Play or Playing to Pretend: The Case of Autism

Social engagement plays a significant role. One study of toddlers at high genetic risk for autism found that those who went on to receive an autism diagnosis showed both less pretend play and less social engagement with their parents. When the researchers controlled for cognitive and language development, the group difference in pretending was no longer significant, suggesting that pretend play deficits in autism may be partly downstream of broader differences in social motivation and communication.13PubMed Central. Pretend Play and Social Engagement in Toddlers at High and Low Genetic Risk for Autism Spectrum Disorder This matters because it shifts the intervention target: supporting pretend play in children with autism may depend heavily on supporting social engagement first.

Cultural Variation in Pretend Play

Not all children pretend in the same ways, and cultural context shapes both the frequency and content of pretend play. A comparison of Korean-American and Anglo-American preschoolers found that Anglo-American children engaged in more pretend play during free-play periods. In a more structured experimental setting, both groups pretended at similar rates, but the content diverged sharply. Korean-American children’s pretend scenarios revolved around everyday activities and family roles, while Anglo-American children were more likely to invent themes involving environmental danger and fantastical elements.14PubMed. Social pretend play in Korean- and Anglo-American preschoolers

These differences reflect broader cultural values. Cultures that emphasize social harmony and family obligation tend to produce pretend play centered on domestic and relational themes. Cultures that emphasize individual exploration and autonomy tend to produce more adventurous, fantastical pretend scenarios. Neither style is “better” for development. Both give children practice with the cognitive skills pretense requires; they just do it through different narrative content. The finding is a useful corrective against assuming that the loud, imaginative pretend play common in Western preschools is the default or optimal form.

Pretense as Emotional Practice

Pretend play gives children a safe space to rehearse emotional experiences. A child pretending to be scared of a monster, or playing out a scene where a stuffed animal goes to the hospital, is processing real emotions through a fictional frame. A systematic review of non-therapeutic play in children aged three to seven found that having sufficient autonomy during play, combined with support for the child’s own perspective, helped children not only work through negative feelings but also develop skills they could apply to future stressful situations.15PubMed Central. Non-therapeutic play to overcome negative emotional symptoms and improve emotional intelligence in children aged 3–7: a systematic review

This is distinct from therapeutic play used in clinical settings, where a trained professional guides the process. What the review highlighted is that ordinary, everyday pretend play in homes and classrooms already carries emotional benefits. The key ingredients appear to be the child’s sense of control over the narrative and the presence of a responsive adult who supports without directing. When those conditions are met, pretend play becomes a kind of low-stakes emotional laboratory.

Pretense in the Classroom

Educators have increasingly recognized pretend play as more than recess filler. Research on guided pretend play in digital education found that teachers can effectively step into pretend scenarios by taking on roles themselves, either as play leaders who set the scenario or as co-players who participate alongside children. Within these roles, teachers modeled behaviors like assigning tasks or thinking aloud, scaffolding children’s learning about real-world topics through the pretend frame.16ScienceDirect / Learning and Instruction. Digital education through guided pretend play The approach works because the pretend frame naturally lowers anxiety about getting things wrong and keeps children engaged in ways that direct instruction often doesn’t.

The broader point about pretend play and education is worth stating plainly: because pretense engages language, executive function, social cognition, and emotional regulation simultaneously, it functions as a kind of cognitive multivitamin. This doesn’t mean free play should replace structured instruction, but it does suggest that squeezing imaginative play out of the school day in favor of more worksheets comes at a cost that’s hard to measure on standardized tests.

Pretense Beyond Childhood

Adults don’t stop pretending; they just do it differently. Acting is the most obvious adult form of pretense, and as the neuroimaging research mentioned earlier shows, it involves genuine changes in self-representation, not just reciting lines. But adult pretense extends well beyond the stage.

Social masking, the practice of concealing aspects of your true self in social situations, is a form of pretense that nearly everyone engages in to some degree. Research comparing autistic and non-autistic adults found that mimicry of others is a common masking strategy across both groups, and that both reported feeling exhausted by the effort. Both groups also described feeling disconnected from their true sense of identity as a result of sustained masking.17PubMed Central. “Masking Is Life”: Experiences of Masking in Autistic and Nonautistic Adults For autistic adults, the stakes are often higher because the gap between natural behavior and social expectations can be wider, making the pretense more effortful and the exhaustion more severe. But the underlying mechanism, performing a version of yourself that doesn’t fully match your internal experience, is shared.

This kind of everyday social pretense sits on a spectrum. At the mild end, you have politeness norms: smiling at a colleague’s unfunny joke, expressing interest in a topic that bores you, adopting a professional demeanor when you’d rather be casual. At the more extreme end, social pretense shades into deception, impression management, and strategic self-presentation. The line between socially adaptive pretense and manipulative deception is blurry, and most people navigate it intuitively without giving it much thought.

When Pretense Becomes Pathological

At the far end of the spectrum, pretense can take on clinical dimensions. Malingering is the deliberate fabrication of symptoms for a concrete external benefit, like avoiding military deployment or securing disability payments. Factitious disorder involves the same deliberate production of symptoms but without an obvious external reward; the goal appears to be assuming the role of a sick person for its own sake.18PubMed. Identifying and Managing Malingering and Factitious Disorder in the Military

Both conditions involve sustained, purposeful pretense, but they’re surprisingly difficult to detect because the person doing the pretending is often skilled at it and highly motivated to succeed. The distinction between them matters clinically: malingering is not a psychiatric diagnosis (it’s classified as a condition that may be a focus of clinical attention), while factitious disorder is a formal mental health diagnosis. Both are rare enough that most clinicians encounter them infrequently, which paradoxically makes them harder to recognize when they do appear.

Evolutionary Roots of Pretend Play

Humans aren’t the only species that pretends. Chimpanzees in both captive and wild settings have been documented engaging in all categories of imaginary play defined by researchers studying human children, including object substitution and imaginary object use. These observations provide evidence for continuity between human and nonhuman primate cognition and suggest that the capacity for pretense has deep evolutionary roots predating the human lineage.19Human Evolution. Imaginary Play in chimpanzees (Pan troglodytes)

Why would pretense have been preserved by natural selection? One possibility is that pretend play serves as a low-risk way to practice skills that would be dangerous or costly to learn through real experience. A young primate that rehearses fighting, fleeing, or nurturing through pretend play gains experience with those behaviors without risking injury or social consequences. Another possibility is that pretense is a byproduct of the more general cognitive ability to represent things that aren’t immediately present, an ability that’s useful for planning, communication, and social coordination. These explanations aren’t mutually exclusive; pretense may be both directly adaptive and a side effect of other adaptive capacities.

The fact that chimpanzees pretend, but that human pretend play is vastly more elaborate, suggests that something in the human cognitive toolkit turbocharged the capacity. Language is the most likely accelerant. Once you can tell someone else what you’re pretending, entire shared fictional worlds become possible, and with them, the kind of collaborative pretend play that dominates human childhood.

Confabulation and the Breakdown of the Reality-Pretense Boundary

One of the most striking features of healthy pretense is that the pretender almost always knows the difference between what is real and what is pretended. Even very young children, when asked directly, will tell you that the banana isn’t really a phone. This ability to maintain the reality-pretense boundary depends on intact prefrontal and memory systems. When those systems degrade, as in certain forms of dementia, the boundary can collapse. Confabulation, the production of false memories or narratives without intent to deceive, represents a kind of involuntary pretense: the person generates non-real content but believes it to be true. Research on confabulation in Alzheimer’s disease suggests the phenomenon isn’t tied to damage in a single brain area but has a complex origin, potentially linked to the brain’s inability to suppress irrelevant information during memory retrieval.20Frontiers in Psychology. Confabulations in Cases of Dementia: Atypical Early Sign of Alzheimer’s Disease or Misleading Feature in Dementia Diagnosis?

Confabulation is useful to consider alongside pretense precisely because it shows what happens when the key ingredient, the awareness that a representation doesn’t match reality, goes missing. Healthy pretense, whether it’s a child playing house or an actor delivering a monologue, always involves that dual awareness: this is happening in the fiction, and I know it’s fiction. When neurological disease removes that awareness, the same capacity for generating non-literal representations becomes a source of confusion rather than enrichment. The contrast underscores that pretense isn’t just about imagining things; it’s about imagining things while keeping one foot firmly planted in the real.
