Evolutionary psychologists investigate how such relationships could have conferred adaptive advantages, particularly in the context of resource sharing, mutual defense, and social support.
- Heritability of IntelligenceHeritability of intelligence refers to the proportion of variance in intelligence test scores within a given population that can be attributed to genetic differences among individuals. It is a statistical concept that describes population-level variation, not the degree to which an individual's intelligence is determined by their genes.
- Hunter-gatherer Hypothesis of Spatial CognitionThe hunter-gatherer hypothesis of spatial cognition proposes that human spatial abilities, particularly those related to navigation, evolved under the selective pressures of a hunter-gatherer lifestyle, leading to specialized cognitive adaptations for tasks such as foraging, tracking, and wayfinding across diverse environments. This perspective suggests that the demands of ancestral subsistence strategies shaped the architecture of human spatial intelligence.
- Imagination and PlanningImagination and planning refer to cognitive capacities that enable organisms to mentally simulate future events, consider alternative courses of action, and devise strategies to achieve goals. From an evolutionary perspective, these abilities are crucial for navigating complex social and physical environments, facilitating adaptive behaviors such as foraging, predator avoidance, and social cooperation.
- Imitation in Evolutionary PerspectiveImitation, the copying of observed actions, is a fundamental mechanism for cultural transmission and social learning, playing a crucial role in the development of complex behaviors and the accumulation of knowledge across generations. From an evolutionary perspective, the capacity for imitation is understood as an adaptation that confers significant fitness advantages by enabling efficient learning without the costs of individual trial-and-error.

This entry explores how evolutionary theory informs our understanding of the origins, functions, and variability of cognitive abilities often grouped under the rubric of intelligence.
- Joint AttentionJoint attention refers to the shared focus of two or more individuals on the same object or event, mediated by eye gaze, pointing, or other communicative gestures. It is a fundamental social-cognitive skill crucial for language acquisition, social learning, and the development of theory of mind, and its evolutionary origins are debated.
- Kinship RecognitionKinship recognition refers to the evolved psychological mechanisms that enable organisms to identify and differentiate genetic relatives from non-relatives, influencing social behaviors such as altruism, mate choice, and conflict resolution. This capacity is central to understanding the evolution of sociality and the application of Hamilton's rule in various species, including humans.
- Machiavellian IntelligenceMachiavellian intelligence refers to the suite of cognitive abilities that evolved to navigate and exploit complex social relationships within a group, particularly through strategic deception, manipulation, and alliance formation. This hypothesis posits that the demands of social living, rather than ecological challenges, were the primary drivers of primate brain evolution and the development of higher cognitive functions.
- Massive Modularity HypothesisThe massive modularity hypothesis proposes that the human mind is largely, if not entirely, composed of a great number of specialized, domain-specific computational devices, or modules, each designed by natural selection to solve a particular adaptive problem faced by our ancestors. This view contrasts with models positing a few general-purpose cognitive mechanisms, and it is a foundational concept in much of evolutionary psychology.

- Mental Time TravelMental time travel (MTT) refers to the cognitive capacity to mentally project oneself into the past (episodic memory) or the future (episodic foresight), enabling individuals to re-experience past events or pre-experience future ones. This capacity is considered a hallmark of human cognition, with significant implications for planning, decision-making, and social behavior.
- Minimal-Group ParadigmThe minimal-group paradigm is an experimental method used to investigate the minimal conditions under which individuals show favoritism toward their own group and discrimination against an outgroup. It demonstrates that mere categorization into arbitrary groups, even without prior interaction or shared history, is sufficient to elicit intergroup bias, offering insights into the evolved psychological mechanisms underlying group behavior.
- Mirror Neurons and LanguageMirror neurons are a class of visuomotor neurons that discharge both when an individual performs an action and when they observe another individual performing a similar action. Their discovery led to hypotheses proposing a fundamental role in language evolution and processing, particularly concerning action understanding and imitation.
- Modularity of MindThe modularity of mind hypothesis proposes that the mind is composed of distinct, specialized computational units, or modules, each dedicated to solving specific problems. This concept is central to evolutionary psychology, which often posits that these modules are adaptations shaped by natural selection to address recurrent challenges faced by ancestral humans.
- Natural PedagogyNatural pedagogy is a theory positing that humans possess an evolved, species-specific cognitive adaptation enabling the efficient and rapid transmission of cultural knowledge from experienced individuals to novices. This system relies on specific communicative cues from the teacher and an innate preparedness in the learner to interpret these cues as conveying generalizable, culturally relevant information.
- Numerical cognition in non-humansNumerical cognition in non-human animals refers to their capacity to process and represent numerical information, challenging the long-held view that such abilities are uniquely human and providing insights into the evolutionary origins of mathematical thought.
- Object Location MemoryObject location memory refers to the cognitive ability to remember where specific objects are situated in space, a critical function for navigating and interacting with the environment. In evolutionary psychology, this capacity is often examined for its potential sex differences and adaptive significance in ancestral foraging contexts.
- Overimitation in ChildrenOverimitation refers to the tendency of human children to meticulously copy all observed actions, including causally irrelevant ones, when learning from others. This phenomenon is considered a key mechanism for cultural transmission, enabling the faithful replication of complex behaviors and the accumulation of cultural knowledge across generations.
- Pathogen avoidance and prejudicePathogen avoidance theory proposes that evolved psychological mechanisms designed to detect and avoid infectious disease agents can influence social cognition, potentially contributing to various forms of prejudice and xenophobia. This perspective suggests that certain social biases may be downstream consequences of a disease-avoidance system that errs on the side of caution.
- Prospective MemoryProspective memory refers to the ability to remember to perform an intended action at a future point in time or in response to a specific cue. From an evolutionary perspective, this cognitive function is crucial for planning, goal-directed behavior, and coordinating social interactions, contributing significantly to an organism's survival and reproductive success.
- Reasoning about ContagionReasoning about contagion refers to a suite of cognitive mechanisms evolved to detect, avoid, and manage infectious diseases, which have posed a significant threat to survival and reproduction throughout human evolutionary history. This domain-specific reasoning system is hypothesized to operate largely outside conscious awareness, influencing perceptions, emotions, and behaviors related to disease avoidance.
- Reverse engineering the mindReverse engineering the mind is a central methodological metaphor in evolutionary psychology, proposing that the human mind, like complex artifacts, can be understood by inferring its design and function from its observable outputs. This approach posits that the mind consists of a collection of evolved computational mechanisms designed to solve recurrent adaptive problems faced by our ancestors.
- Sally-Anne TaskThe Sally-Anne task is a classic false-belief test used in developmental psychology and cognitive science to assess an individual's Theory of Mind (ToM), the ability to attribute mental states—beliefs, desires, intentions—to oneself and others. Its significance in evolutionary psychology lies in its utility for investigating the developmental trajectory and potential evolutionary origins of ToM, a crucial social cognitive capacity.
- Sex Differences in Spatial CognitionSex differences in spatial cognition refer to consistent, statistically significant disparities observed between males and females in various spatial abilities, with evolutionary psychology exploring their potential adaptive origins related to ancestral division of labor and reproductive strategies.
- Snake Detection TheorySnake Detection Theory posits that the unique visual and cognitive adaptations of primates, particularly their acute vision and specialized neural circuitry, evolved primarily as a defense mechanism against snakes. This theory suggests that the persistent predatory threat posed by snakes throughout primate evolutionary history drove significant selective pressures on primate sensory and cognitive systems.
- Social Brain HypothesisThe social brain hypothesis posits that the cognitive demands of living in complex, stable social groups drove the evolution of larger brains, particularly the neocortex, in primates. This framework suggests a direct relationship between group size and brain size, offering an evolutionary explanation for human cognitive capacities.
- The Cognitive NicheThe cognitive niche hypothesis proposes that humans evolved to occupy a unique ecological niche defined by their capacity for complex reasoning, social learning, and technological innovation. This framework posits that intelligence, rather than specialized physical adaptations, became the primary means by which humans overcome environmental challenges and outcompete other species.
- Theory of MindTheory of Mind (ToM) refers to the cognitive capacity to attribute mental states—beliefs, desires, intentions, knowledge, and emotions—to oneself and to others, and to understand that these mental states can differ from one's own and can predict behavior. This capacity is considered fundamental for complex social interactions and is a central topic in evolutionary psychology due to its implications for human cooperation, communication, and cultural development.
- Wason Selection TaskThe Wason Selection Task is a classic problem in the psychology of reasoning, originally designed to test formal logical abilities. Its subsequent reformulation by Leda Cosmides to incorporate social contract theory became a foundational argument for the modularity of human cognitive architecture, particularly for domain-specific adaptations for detecting cheaters in social exchanges.
- Wayfinding StrategiesWayfinding strategies encompass the cognitive and behavioral processes organisms use to navigate their environment, locate resources, and return to specific places. From an evolutionary perspective, effective wayfinding is crucial for survival and reproduction, enabling access to food, water, mates, and safe havens.
- Working Memory and Evolved CapacityWorking memory refers to the cognitive system responsible for temporarily holding and manipulating information relevant to ongoing tasks, a capacity widely considered fundamental to higher-order cognition. Evolutionary psychology examines working memory not merely as a general cognitive resource, but as a specialized adaptation shaped by ancestral selection pressures to solve recurrent problems.
