Difficulty: Introductory to Intermediate. Prerequisites: Familiarity with Piaget's sensorimotor period and basic concepts of attachment.
This topic covers how infants develop a sense of who they are, from the earliest bodily awareness to recognising themselves as distinct individuals with category memberships. It also covers related cognitive milestones (memory structures like scripts and autobiographical memory) and the emergence of self-conscious emotions. This material sits alongside the language development covered in companion notes, and together they form the core of PSY 3215's treatment of the second year of life. You will want a basic understanding of Piaget's sensorimotor stages and of caregiver-infant attachment before diving in.
Infants move through three layers of self-awareness: the ecological self (body in the world), the existential self ("I am a separate person"), and the categorical self ("I am a baby, I am female"). Alongside this, they build cognitive tools like scripts and autobiographical memory, and begin experiencing self-conscious emotions such as shame and pride. Expect exam questions testing whether you can distinguish these three selves and link them to emotional development.
Ecological self
The ability to experience the body and its senses, feelings, and movements in relation to the environment. Think of it as the most basic layer of selfhood: the infant knows where their body ends and the world begins.
Existential self
The ability to recognise one's own features as different from someone else's, along with an awareness of the self as a whole, recognisable person distinct from other people. In simple terms, this is the "I exist as me, not you" realisation.
Categorical self
A concept of the self as belonging to one or more categories, such as baby or female. Think of it as the child beginning to label themselves the way they label objects.
Self-conscious emotion
An emotion that requires an awareness of an existential self in relation to an existential other. Examples include shame, embarrassment, guilt, and pride. In simple terms, you cannot feel embarrassed unless you understand that someone else is watching and judging.
Autobiographical memory
The ability to remember experiences verbally. Think of it as the beginning of a personal life story: the child can talk about things that happened to them.
Script
A form of conceptual organisation in which events are remembered according to the sequences in which they usually occur. In simple terms, a script is a mental template for "how things go" (e.g., the routine of bathtime: undress, fill tub, wash, dry, pyjamas).
Tertiary circular reactions
The fact that new means are invented to achieve goals by trial and error experimentation. Think of it as the infant becoming a little scientist, deliberately varying their actions to see what happens.
Transitional object
An object to which the infant develops an attachment; it may be used for comfort in the absence of the caregiver. In simple terms, this is the beloved blanket or stuffed animal that helps a child cope when their parent is away.
Relationship
A lasting pattern of communication between two or more people in which past encounters provide a historical background for future encounters. Think of it as the accumulated history between two people that shapes how they interact going forward.
The ecological self comes first. The infant experiences their own body, its senses and movements, as situated in the physical environment. This is pre-reflective: the baby does not "think" about having a self, they simply experience one.
The existential self develops as the infant begins to recognise that they are a distinct, whole person, separate from others. The classic test is mirror self-recognition (the rouge test), typically emerging around 18 months.
The categorical self builds on the existential self. Once the child knows "I am me," they start attaching labels: "I am a boy," "I am little." This is the beginning of identity as a set of social categories.
Tertiary circular reactions (Piaget's substage 5, roughly 12 to 18 months) mark a shift from repeating known actions to deliberately experimenting with new ones. The infant varies their behaviour on purpose to see what effect it has.
Scripts emerge as the child organises repeated experiences into predictable sequences. A script for "going to the park" might be: put on shoes, get in car, walk to swings, come home. These are foundational to event memory.
Autobiographical memory develops when the child can verbally recall personal experiences. It depends on language and on the sense of a continuous self over time. Early autobiographical memories are typically simple and supported by adult conversation ("Remember when we went to the zoo?").
Self-conscious emotions (shame, embarrassment, guilt, pride) require the existential self. The child must be aware that others can observe and evaluate them.
These emotions appear later than basic emotions (joy, anger, fear) precisely because they depend on this cognitive prerequisite.
Transitional objects (a favourite blanket, a stuffed toy) serve as a bridge between the caregiver's presence and the child's growing independence. They are a normal and healthy part of emotional development.
"The ecological self and the existential self are the same thing." They are not. The ecological self is about bodily experience in the environment. The existential self is about recognising oneself as a distinct person, separate from others.
"Self-conscious emotions appear at the same time as basic emotions." They do not. Basic emotions (joy, anger, fear) emerge in the first year. Self-conscious emotions (shame, pride, guilt) require the existential self and appear later, typically in the second year.
"A transitional object means the child is insecurely attached." This is a common misreading. Transitional objects are a normal coping mechanism, not a sign of attachment problems.
"Autobiographical memory and script memory are the same thing." Scripts are generalised templates for recurring events. Autobiographical memory is the recall of specific, personal experiences. A child might have a script for "going to nursery" without being able to recall a particular day there.
⚠️ Be able to distinguish all three selves (ecological, existential, categorical) and state the order in which they develop.
⚠️ Know that self-conscious emotions depend on the existential self and cannot emerge before it.
⚠️ Understand the difference between scripts (generalised event sequences) and autobiographical memory (specific personal recall).
⚠️ Be ready to explain what tertiary circular reactions are and place them in Piaget's substage sequence.
True or False: The ecological self involves recognising oneself as distinct from other people. (False, that is the existential self. The ecological self is about bodily experience in the environment.)
Fill in the blank: Shame, embarrassment, guilt, and pride are examples of ______ emotions. (self-conscious)
True or False: A child's teddy bear that provides comfort when a parent leaves is called a transitional object. (True)
Fill in the blank: When an infant deliberately drops a toy in different ways to see what happens, this is an example of ______. (tertiary circular reactions)
True or False: Scripts and autobiographical memory refer to the same type of recall. (False, scripts are generalised event templates; autobiographical memory is recall of specific personal experiences.)
Q: Explain the difference between the ecological self and the existential self. At what approximate age does each emerge?
A: The ecological self is the earliest form of self-awareness, involving the experience of one's body, senses, and movements in relation to the environment. It is present from early infancy. The existential self emerges later (around 18 months), when the child recognises themselves as a distinct, whole person separate from others, as demonstrated by mirror self-recognition.
Q: Why can a six-month-old feel anger but not shame?
A: Shame is a self-conscious emotion that requires an existential self, specifically the awareness that others can observe and evaluate you. At six months, the infant has basic emotions but has not yet developed this level of self-awareness.
Q: A two-year-old describes her morning routine as "wake up, eat breakfast, brush teeth, go to nursery." What cognitive structure is she using?
A: She is using a script, a form of conceptual organisation in which events are remembered according to the sequence in which they usually occur.
Q: How do tertiary circular reactions differ from secondary circular reactions?
A: In secondary circular reactions, the infant repeats actions that produced an interesting result. In tertiary circular reactions, the infant deliberately varies their actions to discover new outcomes, essentially experimenting through trial and error.
Q: What is the function of a transitional object, and is its use a cause for concern?
A: A transitional object (such as a blanket or stuffed animal) provides comfort in the caregiver's absence. Its use is a normal part of emotional development, not a sign of insecure attachment.
The three-selves framework connects directly to Piaget's sensorimotor substages: the ecological self maps onto early sensorimotor awareness, while the existential and categorical selves emerge as the child approaches the preoperational stage. Self-conscious emotions tie into later work on socialisation, moral development, and theory of mind. Scripts and autobiographical memory are foundational to the study of cognitive development throughout childhood.
