Introduction
There are questions regarding what part of theBody
Bodily (self-)awarenessHealth
In health and medicine, body awareness is a construct that refers to a person's overall ability to direct their focus on various internal sensations accurately. Both proprioception andHuman development
Bodily self-awareness in human development refers to one's awareness of their body as a physical object, with physical properties, that can interact with other objects. Tests have shown that at the age of only a few months old, toddlers are already aware of the relationship between the proprioceptive and visual information they receive. This is called first-person self-awareness. At around 18 months old and later, children begin to develop reflective self-awareness, which is the next stage of bodily awareness and involves children recognizing themselves in reflections, mirrors, and pictures. Children who have not obtained this stage of bodily self-awareness yet will tend to view reflections of themselves as other children and respond accordingly, as if they were looking at someone else face to face. In contrast, those who have reached this level of awareness will recognize that they see themselves, for instance seeing dirt on their face in the reflection and then touching their own face to wipe it off. Slightly after toddlers become reflectively self-aware, they begin to develop the ability 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.Non-human animals
The most relevant conducted "mirror tests" have been done onApes
Chimpanzees and other apes – species which have been studied extensively – compare the most to humans with the most convincing findings and straightforward evidence in the relativity of self-awareness in animals so far.Dolphins
Dolphins were put to a similar test and achieved the same results. Diana Reiss, a psycho-biologist at the New York Aquarium discovered thatMagpies
Researchers also used the mark test or mirror test to study theThe four stages in the mirror test
During the test, the experimenter looks for the animals to undergo four stages: # social response, # physical mirrorThree "types" of self-awareness
David DeGrazia states that there are three types of self-awareness in animals. #Bodily self-awareness ##This sense of awareness allows animals to understand that they are different from the rest of the environment; it is also the reason why animals do not eat themselves. Bodily-awareness also includes proprioception and sensation. #Social self-awareness ##This type of awareness is seen in highly social animals and is the awareness that they have a role within themselves in order to survive. This type of awareness allows animals to interact with each other. #Introspective self-awareness ##This awareness is responsible for animals to understand feelings, desires, and beliefs.The "red-spot" technique
The red-spot technique created and experimented by Gordon G. Gallup studies self-awareness in animals (primates). In this technique, a red odorless spot is placed on an anesthetized primate's forehead. The spot is placed on the forehead so that it can only be seen through a mirror. Once the individual awakens, independent movements toward the spot after seeing their reflection in a mirror are observed. During the red-spot technique, after looking in the mirror, chimpanzees used their fingers to touch the red dot that was on their forehead and, after touching the red dot they would even smell their fingertips. "Animals that can recognize themselves in mirrors can conceive of themselves," says Gallup. Another prime example are elephants. Three elephants were exposed to large mirrors where experimenters studied the reaction when the elephants saw their reflection. These elephants were given the "litmus mark test" in order to see whether they were aware of what they were looking at. This visible mark was applied on the elephants and the researchers reported a large progress with self-awareness. The elephants shared this success rate with other animals such as monkeys and dolphins.Cooperation and evolutionary problems
AnPsychology
Self-awareness has been called "arguably the most fundamental issue in psychology, from both a developmental and an evolutionary perspective." Self-awareness theory, developed by Duval and Wicklund in their 1972 landmark book ''A theory of objective self awareness'', states that when we focus our attention 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. However self-awareness is not to 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 made self-aware. People will be negatively affected if they don't 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 accuracy of personal memory. In one of Andreas Demetriou's neo-Piagetian theories of cognitive development, self-awareness develops systematically from birth through the life span and it is a major factor for the development of general inferential processes. Moreover, a series of recent studies showed that self-awareness about cognitive processes participates in generalDevelopmental 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 own body and mental 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 it is considered to be an indicator that there is some concept of the self. It is developed through an early sense of non-self components using sensory and memory sources. In developing self–awareness through self-exploration and social experiences one can broaden one's social world and become more familiar with the self. According to Emory University's Philippe Rochat, there are five levels of self-awareness which unfold in early development and six potential prospects ranging from "Level 0" (having no self-awareness) advancing complexity to "Level 5" (explicit self-awareness). * Level 0: Confusion. At this level the individual has a degree of zero self-awareness. This person is unaware of any mirror reflection or the mirror itself. They perceive the mirror as an extension of their environment. Level 0 can also be displayed when an adult frightens himself in a mirror mistaking his own reflection as another person just for a second. * Level 1: Differentiation. The individual realizes the mirror is able to reflect things. They see that what is in the mirror is different 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. At this point an individual can link the movements on the mirror to what is perceived within their own body. This is the first hint of self-exploration on a projected surface where what is visualized on the mirror is special to the self. * Level 3: Identification. This stage is characterized by the new ability to identify self: an individual can now see that what's in the mirror is not another person but actually them. It is seen when a child, instead of referring to the mirror while referring to themselves, refers to themselves while looking in the mirror. * Level 4: Permanence. Once an individual reaches this level they can identify the self beyond the present mirror imagery. They are 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. They begin to understand they can be in the mind of others. For instance, how they are seen from a public standpoint.Infancy and early childhood
It is to be kept in mind that as an infant comes into this world, they have no concept of what is around them, nor for the significance of others around them. It is throughout the first year that they gradually begin to acknowledge that their body is actually separate from that of their mother, and that they are an "active, causal agent in space". By the end of the first year, they additionally realize that their movement, as well, is separate from movement of the mother. That is a huge advance, yet they are still quite limited and cannot yet know what they look like, "in the sense that the infant cannot recognize its own face". By the time an average toddler reaches 18–24 months, they will discover themselves and recognize their own reflection in the mirror, however research has found that this age varies widely with differing socioeconomic levels and differences relating to culture and parenting. They begin to acknowledge the fact that the image in front of them, who happens to be them, moves; indicating that they appreciate and can consider the relationship between cause and effect that is happening. By the age of 24 months the toddler will observe and relate their own actions to those actions of other people and the surrounding environment. Once an infant has gotten a lot of experience, and time, in front of a mirror, it is only then that they are able to recognize themselves in the reflection, and understand that it is them. For example, in a study, an experimenter took a red marker and put a fairly large red dot (so it is visible by the infant) on the infant's nose, and placed them in front of a mirror. Prior to 15 months of age, the infant will not react to this, but after 15 months of age, they will either touch their nose, wondering what it is they have on their face, or point to it. This indicates the appearance that they recognize that the image they see in the reflection of the mirror is themselves. There is somewhat of the same thing called the mirror-self recognition task, and it has been used as a research tool for numerous years, and has given, and lead to, key foundations of the infant's sense/awareness of self. For example, "for Piaget, the objectification of the bodily self occurs as the infant becomes able to represent the body's spatial and causal relationship with the external world".Piaget
Around school age a child's awareness of personal memory transitions into a sense of one's own self. At this stage, a child begins to develop interests along with likes and dislikes. This transition enables the awareness of an individual's past, present, and future to grow as conscious experiences are remembered more often. As a preschooler, they begin to give much more specific details about things, instead of generalizing. For example, the preschooler will talk about the Los Angeles Lakers basketball team, and the New York Rangers hockey team, instead of the infant just stating that he likes sports. Furthermore, they will start to express certain preferences (e.g., Tod likes mac and cheese) and will start to identify certain possessions of theirs (e.g., Lara has a bird as a pet at home). At this age, the infant is in the stage Piaget names the '' pre operational'' stage of development. The infant is very inaccurate at judging themselves because they do not have much to go about. For example, an infant at this stage will not associate that they are strong with their ability to cross the jungle gym at their school, nor will they associate the fact that they can solve a math problem with their ability to count.Adolescence
One becomes conscious of their emotions duringMental health
As children reach their adolescent stages of life, the acute sense of emotion has widened into a meta cognitive state in which mental health issues can become more prevalent due to their heightened emotional and social development. There are elements of contextual behavioral science such as Self-as-Content, Self-as-Process and Self-as-Context, involved with adolescent self-awareness that can associate with mental health. Moran, Almada, and McHugh presented the idea that these domains of self are associated with adolescent mental health in various capacities. Anger management is also a domain of mental health that is associated with the concept of self-awareness in teens. Self-awareness training has been linked to lowering anger management issues and reducing aggressive tendencies in adolescents: "Persons having sufficient self-awareness promote relaxation and awareness about themselves and when going angry, at the first step they become aware of anger in their inside and accept it, then try to handle it".Philosophy
Locke
An early philosophical discussion of self-awareness is that of John Locke. Locke was apparently influenced byDisorders
The medical term for not being aware of one's deficits is anosognosia, or more commonly known as a lack of insight. Having a lack of awareness raises the risks of treatment and service nonadherence. Individuals who deny having an illness may be against seeking professional help because they are convinced that nothing is wrong with them. Disorders of self-awareness frequently follow frontal lobe damage. There are two common methods used to measure how severe an individual's lack of self-awareness is. The Patient Competency Rating Scale (PCRS) evaluates self-awareness in patients who have endured a traumatic brain injury. PCRS is a 30-item self-report instrument which asks the subject to use a 5-point Likert scale to rate his or her degree of difficulty in a variety of tasks and functions. Independently, relatives or significant others who know the patient well are also asked to rate the patient on each of the same behavioral items. The difference between the relatives' and patient's perceptions is considered an indirect measure of impaired self-awareness. The limitations of this experiment rest on the answers of the relatives. Results of their answers can lead to a bias. This limitation prompted a second method of testing a patient's self-awareness. Simply asking a patient why they are in the hospital or what is wrong with their body can give compelling answers as to what they see and are analyzing.Anosognosia
Anosognosia was a term coined by Joseph Babinski to describe the clinical condition in which an individual suffered from left hemiplegia following a right cerebral hemisphere stroke yet denied that there were any problems with their left arm or leg. This condition is known as anosognosia for hemiplegia (AHP). This condition has evolved throughout the years and is now used to describe people who lack subjective experience in both neurological and neuropsychological cases. A wide variety of disorders are associated with anosognosia. For example, patients who are blind from corticalDissociative identity disorder
Dissociative identity disorder or multiple personality disorder (MPD) is a disorder involving a disturbance of identity in which two or more separate and distinct personality states (or identities) control an individual's behavior at different times. One identity may be different from another, and when an individual with DID is under the influence of one of their identities, they may forget their experiences when they switch to the other identity. "When under the control of one identity, a person is usually unable to remember some of the events that occurred while other personalities were in control." They may experience time loss, amnesia, and adopt different mannerisms, attitudes, speech and ideas under different personalities. They are often unaware of the different lives they lead or their condition in general, feeling as though they are looking at their life through the lens of someone else, and even being unable to recognize themselves in a mirror. Two cases of DID have brought awareness to the disorder, the first case being that of Eve. This patient harbored three different personalities: Eve White the good wife and mother, Eve Black the party girl, and Jane the intellectual. Under stress, her episodes would worsen. She even tried to strangle her own daughter and had no recollection of the act afterward. Eve went through years of therapy before she was able to learn how to control her alters and be mindful of her disorder and episodes. Her condition, being so rare at the time, inspired the book and film adaptation '' The Three Faces of Eve'', as well as a memoir by Eve herself entitled ''I'm Eve''. Doctors speculated that growing up during the Depression and witnessing horrific things being done to other people could have triggered emotional distress, periodic amnesia, and eventually DID. In the second case, Shirley Ardell Mason, or Sybil, was described as having over 16 separate personalities with different characteristics and talents. Her accounts of horrific and sadistic abuse by her mother during childhood prompted doctors to believe that this trauma caused her personalities to split, furthering the unproven idea that this disorder was rooted in child abuse, while also making the disorder famous. In 1998 however, Sybil's case was exposed as a sham. Her therapist would encourage Sybil to act as her other alter ego although she felt perfectly like herself. Her condition was exaggerated in order to seal book deals and television adaptations. Awareness of this disorder began to crumble shortly after this finding. To this day, no proven cause of DID has been found, but treatments such as psychotherapy, medications, hypnotherapy, and adjunctive therapies have proven to be very effective.Autism spectrum disorder
Autism spectrum disorder (ASD) is a range of neurodevelopmental disabilities that can adversely impact social communication and create behavioral challenges (Understanding Autism, 2003). "Autism spectrum disorder (ASD) and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized, in varying degrees, by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors." ASDs can also cause imaginative abnormalities and can range from mild to severe, especially in sensory-motor, perceptual and affective dimensions. Children with ASD may struggle with self-awareness and self acceptance. Their different thinking patterns and brain processing functions in the area of social thinking and actions may compromise their ability to understand themselves and social connections to others. About 75% diagnosed autistics are mentally handicapped in some general way and the other 25% diagnosed with Asperger's Syndrome show average to good cognitive functioning. It is well known that children suffering from varying degrees of autism struggle in social situations. Scientists at the University of Cambridge have produced evidence that self-awareness is a main problem for people with ASD. Researchers used functional magnetic resonance scans (FMRI) to measure brain activity in volunteers being asked to make judgments about their own thoughts, opinions, preferences, as well as about someone else's. One area of the brain closely examined was the ventromedial pre-frontal cortex (vMPFC) which is known to be active when people think about themselves. A study out of Stanford University has tried to map out brain circuits with understanding self-awareness in Autism Spectrum Disorders. This study suggests that self-awareness is primarily lacking in social situations but when in private they are more self-aware and present. It is in the company of others while engaging in interpersonal interaction that the self-awareness mechanism seems to fail. Higher functioning individuals on the ASD scale have reported that they are more self-aware when alone unless they are in sensory overload or immediately following social exposure. Self-awareness dissipates when an autistic is faced with a demanding social situation. This theory suggests that this happens due to the behavioral inhibitory system which is responsible for self-preservation. This is the system that prevents human from self-harm like jumping out of a speeding bus or putting our hand on a hot stove. Once a dangerous situation is perceived then the behavioral inhibitory system kicks in and restrains our activities. "For individuals with ASD, this inhibitory mechanism is so powerful, it operates on the least possible trigger and shows an over sensitivity to impending danger and possible threats. Some of these dangers may be perceived as being in the presence of strangers, or a loud noise from a radio. In these situations self-awareness can be compromised due to the desire of self preservation, which trumps social composure and proper interaction. The Hobson hypothesis reports that autism begins in infancy due to a lack of cognitive and linguistic engagement, which results in impaired reflective self-awareness. In this study ten children with Asperger Syndrome were examined using the Self-understanding Interview. This interview was created by Damon and Hart and focuses on seven core areas or schemas that measure the capacity to think in increasingly difficult levels. This interview will estimate the level of self understanding present. "The study showed that the Asperger group demonstrated impairment in the 'self-as-object' and 'self-as-subject' domains of the Self-understanding Interview, which supported Hobson's concept of an impaired capacity for self-awareness and self-reflection in people with ASD." Self-understanding is a self description in an individual's past, present and future. Without self-understanding it is reported that self-awareness is lacking in people with ASD. Joint attention (JA) was developed as a teaching strategy to help increase positive self-awareness in those with autism spectrum disorder. JA strategies were first used to directly teach about reflected mirror images and how they relate to their reflected image. Mirror Self Awareness Development (MSAD) activities were used as a four-step framework to measure increases in self-awareness in those with ASD. Self-awareness and knowledge is not something that can simply be taught through direct instruction. Instead, students acquire this knowledge by interacting with their environment. Mirror understanding and its relation to the development of self leads to measurable increases in self-awareness in those with ASD. It also proves to be a highly engaging and highly preferred tool in understanding the developmental stages of self- awareness. There have been many different theories and studies done on what degree of self-awareness is displayed among people with autism spectrum disorder. Scientists have done research about the various parts of the brain associated with understanding self and self-awareness. Studies have shown evidence of areas of the brain that are impacted by ASD. Other theories suggest that helping an individual learn more about themselves through Joint Activities, such as the Mirror Self Awareness Development may help teach positive self-awareness and growth. In helping to build self-awareness it is also possible to build self-esteem and self acceptance. This in turn can help to allow the individual with ASD to relate better to their environment and have better social interactions with others.Schizophrenia
Schizophrenia is a chronic psychiatric illness characterized by excessive dopamine activity in the mesolimbic tract and insufficient dopamine activity in the mesocortical tract leading to symptoms of psychosis along with poor cognition in socialization. Under the Diagnostic and Statistical Manual of Mental Disorders, people with schizophrenia have a combination of positive, negative and psychomotor symptoms. These cognitive disturbances involve rare beliefs and/or thoughts of a distorted reality that creates an abnormal pattern of functioning for the patient. The cause of schizophrenia has a substantial genetic component involving many genes. While the heritability of schizophrenia has been found to be around 80%, only about 60% of sufferers report a positive family history of the disorder, and ultimately the cause is thought to be a combination of genetic and environmental factors. It is believed that the experience of stressful life events is an environmental factor that can trigger the onset of schizophrenia in individuals who already are at risk from genetics and age. The level of self-awareness among patients with schizophrenia is a heavily studied topic. Schizophrenia as a disease state is characterized by severe cognitive dysfunction and it is uncertain to what extent patients are aware of this deficiency. Medalia and Lim (2004) investigated patients' awareness of their cognitive deficit in the areas of attention, nonverbal memory, and verbal memory. Results from this study (N=185) revealed large discrepancy in patients' assessment of their cognitive functioning relative to the assessment of their clinicians. Though it is impossible to access one's consciousness and truly understand what a schizophrenic believes, regardless in this study, patients were not aware of their cognitive dysfunctional reasoning. In theBipolar disorder
Bipolar disorder is an illness that causes shifts in mood, energy, and ability to function. Self-awareness is crucial in those suffering from this disease, as they must be able to distinguish between feeling a certain way because of the disorder or because of separate issues. "Personality, behavior, and dysfunction affect your bipolar disorder, so you must 'know' yourself in order to make the distinction." This disorder is a difficult one to diagnose, as self-awareness changes with mood. "For instance, what might appear to you as confidence and clever ideas for a new business venture might be a pattern of grandiose thinking and manic behavior". Issues occur between understanding irrationality in a mood swing and being completely wrapped in a manic episode, rationalizing that the exhibited behaviors are normal. It is important to be able to distinguish what are symptoms of bipolar disorder and what is not. A study done by Mathew et al. was done with the aim of "examining the perceptions of illness in self and among other patients with bipolar disorder in remission". The study took place at the Department of Psychiatry, Christian Medical College, Vellore, India, which is a centre that specializes in the "management of patients with mental and behavioural disorders". Eighty two patients (thirty two female and fifty male) agreed to partake in the study. These patients met the " International Classification of Diseases – 10 diagnostic criteria for a diagnosis of bipolar disorder I or II and were in remission" and were put through a variety of baseline assessments before beginning the study. These baseline assessments included using a vignette, which was then used as an assessment tool during their follow-up. Patients were then randomly divided into two groups, one who would be following a "structured educational intervention programme" (experimental group), while the other would be following "usual care" (control group). The study was based on an interview in which patients were asked an array of open-ended questions regarding topics such as "perceived causes, consequences, severity and its effects on body, emotion, social network and home life, and on work, severity, possible course of action, help-seeking behaviour and the role of the doctor/healer". The McNemar test was then used to compare the patients perspective of the illness versus their explanation of the illness. The results of the study show that the beliefs that patients associated with their illness corresponds with the possible causes of the disorder, whereas "studies done among patients during periods of active psychosis have recorded disagreement between their assessments of their own illness". This ties in to how difficult self-awareness is within people who suffer from bipolar disorder. Although this study was done on a population that were in remission from the disease, the distinction between patients during "active psychosis" versus those in remission shows the evolution of their self-awareness throughout their journey to recovery.Plants
Self-discrimination in plants is found within their roots, tendrils and flowers that avoid themselves but not others in their environment.Self-incompatibility mechanism providing evidence for self-awareness in plants
Self-awareness in plants is a fringe topic in the field of self-awareness, and is researched predominantly by botanists. The claim that plants are capable of perceiving self lies in the evidence found that plants will not reproduce with themselves due to a gene selecting mechanism. In addition, vining plants have been shown to avoid coiling around themselves, due to chemical receptors in the plants' tendrils. Unique to plants, awareness of self means that the plant can recognise self, whereas all other known conceptions of self-awareness involve or are centered on the ability to recognise what is not self.Recognition and rejection of self in plant reproduction
Research by June B. Nasrallah discovered that the plant's pollination mechanism also serves as a mechanism against self-reproduction, which lays out the foundation of scientific evidence that plants could be considered as self-aware organisms. The SI (Self-incompatibility) mechanism in plants is unique in the sense that awareness of self derives from the capacity to recognise self, rather than non-self. The SI mechanism function depends primarily on the interaction between genes ''S''-locus receptor protein kinase (SRK) and ''S''-locus cysteine-rich protein gene (''SCR).'' In cases of self-pollination, SRK and SCR bind to activate SKR, Inhibiting pollen from fertilizing. In cases of cross-pollination, SRK and SCR do not bind and therefore SRK is not activated, causing the pollen to fertilise. In simple terms, the receptors either accept or reject the genes present in the pollen, and when the genes are from the same plant, the SI mechanism described above creates a reaction to prevent the pollen from fertilising.Self-discrimination in the tendrils of the vine ''Cayratia japonica'' mediated by physiological connection
The research by Yuya Fukano and Akira Yamawo provides a link between self-discrimination in vining plants and amongst other classifications where the mechanism discovery has already been established. It also contributes to the general foundation of evidence of self-discrimination mechanisms in plants. The article makes the claim that the biological self-discrimination mechanism that is present in both flowering plants and ascidians, are also present in vining plants. They tested this hypothesis by doing touch tests with self neighbouring and non-self neighbouring pairs of plants. the test was performed by placing the sets of plants close enough for their tendrils to interact with one-another. Evidence of self-discrimination in above-ground plants is demonstrated in the results of the touch testing, which showed that in cases of connected self plants, severed self plants and non-self plants, the rate of tendril activity and likeliness to coil was higher among separated plants than those attached via rhizomes.Theater
Theater also concerns itself with other awareness besides self-awareness. There is a possible correlation between the experience of the theater audience and individual self-awareness. As actors and audiences must not "break" theScience fiction
InRobotics
In order to be "self-aware," robots can use internal models to simulate their own actions.See also
