In the philosophy of self, self-awareness is the awareness and reflection of one's own personality or individuality, including traits, feelings, and behaviors. It is not to be confused with consciousness in the sense of qualia. While consciousness is being aware of one's body and environment, self-awareness is the recognition of that consciousness. Self-awareness is how an individual experiences and understands their own character, feelings, motives, and desires. Because the term is used in both philosophical and psychological contexts, researchers distinguish between different forms of self-awareness, ranging from awareness of consciousness itself to awareness of oneself within social situations.
Definitions and scope
The term self-awareness is used across several disciplines to describe related but distinct phenomena. Broadly, it refers to the capacity to direct attention inward and recognize oneself as an individual, separate from the environment and from other beings. However, researchers distinguish between two main forms: reflective self-awareness and social self-awareness.Focquaert, F.; Braeckman, J.; Platek, S. M. (2008). "An evolutionary cognitive neuroscience perspective on human self-awareness and theory of mind". Philosophical Psychology, 21(1), 47-68. https://doi.org/10.1080/09515080701875156
Reflective self-awareness refers to the recognition of one's own consciousness—the ability to think about thoughts, to know that one is perceiving, feeling, and existing. It is often described as "awareness of awareness" and forms the basis for introspection, metacognition, and personal identity. This sense of self-awareness is studied in philosophy of mind, neuroscience, and comparative cognition, where it is linked to neural processes of reflection and self-recognition.
Social self-awareness refers to understanding oneself as perceived by others and within social contexts. It includes the ability to evaluate one's behavior, emotions, and presentation relative to social norms or expectations. This meaning is common in psychology, where it underlies theories of self-conscious emotions, social behavior, and empathy. In this sense, self-awareness overlaps with self-evaluation, self-monitoring, and self-regulation.Fenigstein, A.; Scheier, M. F.; Buss, A. H. (1975). "Public and private self-consciousness: Assessment and theory". Journal of Consulting and Clinical Psychology, 43(4), 522–527. https://doi.org/10.1037/h0076760
These two meanings often interact—reflective awareness provides the inner model of the self that social awareness then extends to interpersonal situations. In contemporary research, distinguishing between these levels helps clarify how self-awareness can involve both private consciousness and public self-perception.
With this conceptual framework in place, we next examine the neural basis of reflective self-awareness.
Neuroscience
Modern neuroscience treats self-awareness not as the product of a single "center," but as the emergent behavior of interacting brain systems. Functional MRI, lesion, and connectivity studies implicate a distributed network—particularly the medial prefrontal cortex, anterior cingulate cortex, posterior cingulate cortex, and temporoparietal junction—in processes of self-reflection and self-modelling. These regions overlap substantially with the brain's default mode network and engage in metacognitive monitoring—feedback loops in which predictions about internal and external states are continuously compared with incoming sensory and emotional input. Such neural machinery underlies the experience of being aware that one is aware.
Experimental evidence suggests that self-awareness depends on the brain's capacity for metacognition—the monitoring and evaluation of its own processes. Such "monitoring systems" continually compare predicted sensory and emotional states with actual input, generating the experience of being aware of awareness itself. This feedback architecture allows the brain to notice discrepancies between expectation and perception, forming the foundation of conscious self-reflection. This recursive feedback process gives rise to the sensation of being aware of awareness, sometimes described as a "mirror of mirrors" within consciousness.
Neuroscientific models therefore interpret self-awareness as a dynamic property of the brain's integrative and self-modelling systems, not as a function of a single mechanism.
Psychology Self-awareness in psychology encompasses how individuals perceive, evaluate, and regulate their own internal states, actions, and identities. It involves both introspective attention—awareness of thoughts and emotions—and embodied attention—awareness of one's physical presence in the world.Dalla Volta R.; Fasano, F.; Cerasa, A.; Mangone, G.; Quattrone, A.; Buccino, G. (2015) "Walking indoors, walking outdoors: an fMRI study". Front. Psychol. 6:1502. doi: 10.3389/fpsyg.2015.01502
Body awareness Body awareness refers to the ability to perceive one's physical form and position in space as belonging to the self. It combines sensory feedback from proprioception (the sense of muscle and joint position), interoception (the perception of internal bodily states), and visual–spatial input. This integration creates the feeling of embodiment—the sense that "this body is mine."
Psychological and neurological research indicates that body awareness is not fixed but flexible. Experiments such as the rubber-hand illusion demonstrate that visual and tactile cues can alter the perceived boundaries of the body. Disorders like somatoparaphrenia, in which individuals deny ownership of a limb, or depersonalization, in which one feels detached from the body, reveal how fragile this aspect of self-awareness can be.
Body awareness also interacts with emotional and social processes: heightened interoceptive sensitivity has been linked to stronger emotional self-awareness, while disruptions to bodily representation are associated with conditions such as eating disorders and body dysmorphia. These findings suggest that self-awareness arises partly from the brain's dynamic mapping of its own physical state in the world.
Body image Following perceptual embodiment, psychological theories such as objective self-awareness posit that, Self-awareness theory, developed by Duval and Wicklund in their 1972 landmark book A Theory of Objective Self-Awareness, states that when we focus on ourselves, we evaluate and compare our current behavior to our internal standards and values. This elicits a state of objective self-awareness. We become self-conscious as objective evaluators of ourselves. Self-awareness should not be confused with self-consciousness. Various emotional states are intensified by self-awareness. However, some people may seek to increase their self-awareness through these outlets. People are more likely to align their behavior with their standards when they are made self-aware. People are negatively affected if they do not live up to their personal standards. Various environmental cues and situations induce awareness of the self, such as mirrors, an audience, or being videotaped or recorded. These cues also increase the accuracy of personal memory.
Introspection In one of Andreas Demetriou's neo-Piagetian theories of cognitive development, self-awareness develops systematically from birth through the life span and it general inferential processes. Self-awareness about cognitive processes contributes to general intelligence on a par with processing efficiency functions, such as working memory, processing speed, and reasoning.
Self-consciousness Albert Bandura's theory of self-efficacy describes "the belief in one's capabilities to organize and execute the courses of action required to manage prospective situations." A person's belief in their ability to succeed sets the stage for how they think, behave, and feel. Someone with a strong self-efficacy, for example, views challenges as tasks to engage in, and is not easily discouraged by setbacks. Such a person is aware of their flaws and abilities and chooses to utilize these qualities to the best of their ability. Someone with a weak sense of self-efficacy evades challenges and quickly feels discouraged by setbacks. They may not be aware of these negative reactions and therefore, may not be prompted to change their attitude. This concept is central to Bandura's social cognitive theory, "which emphasizes the role of observational learning, social experience, and reciprocal determinism in the development of personality."
Human development
Developmental stages Individuals become conscious of themselves through the development of self-awareness. This particular type of self-development pertains to becoming conscious of one's body and one's state of mind—including thoughts, actions, ideas, feelings, and interactions with others. "Self-awareness does not occur suddenly through one particular behavior: it develops gradually through a succession of different behaviors all of which relate to the self." The monitoring of one's mental states is called metacognition and is considered to be an indicator that there is some concept of the self.
According to Philippe Rochat, there are five levels of self-awareness that unfold in early human development and six potential prospects ranging from "Level 0" (having no self-awareness) advancing complexity to "Level 5" (explicit self-awareness):
Level 0—Confusion: The person is unaware of any mirror reflection or the mirroring itself; they perceive a mirror image as an extension of their environment.
Level 1—Differentiation: The individual realizes the mirror is able to reflect things. They see that what is in the mirror is of a different nature from what is surrounding them. At this level they can differentiate between their own movement in the mirror and the movement of the surrounding environment.
Level 2—Situation: The individual can link the movements on the mirror to what is perceived within their own body.
Level 3—Identification: An individual can now see that what's in the mirror is not another person but actually them.
Level 4—Permanence: The individual is able to identify the self in previous pictures looking different or younger. A "permanent self" is now experienced.
Level 5—Self-consciousness or "meta" self-awareness: At this level, not only is the self seen from a first person view but it is realized that it is also seen from a third person's view. A person who develops self consciousness begins to understand they can be in the mind of others: for instance, how they are seen from a public standpoint.
Infancy and early childhood When a human infant comes into the world, they have no concept of what is around them, nor the significance of others around them. At first "the infant cannot recognize its own face". At only a few months old, infants know the relationship between the proprioceptive and visual information they receive. This is called "first-person self-awareness".
By the time an average toddler reaches 18–24 months, they discover themselves and recognize their own reflection in the mirror, however the exact age varies with differing socioeconomic levels and differences relating to culture and parenting. Those who reach this level of awareness recognize that they see themselves, for instance, seeing dirt on their face in the reflection and then touching their face to wipe it off. Soon after toddlers become reflectively self-aware, they begin to recognize their bodies as physical objects in time and space that interact and impact other objects. For instance, a toddler placed on a blanket, when asked to hand someone the blanket, will recognize that they need to get off it to be able to lift it. This is the final stage of body self-awareness and is called objective self-awareness.
