Object constancy occupies a pivotal position in the depth-psychological corpus as the developmental achievement by which a child internalizes a stable, affectively coherent mental representation of a significant other — most paradigmatically the mother — that persists across absence, frustration, and ambivalence. The concept originates in Mahler's tripartite schema of normal development, where it designates the culminating subphase of separation-individuation: the moment at which the split between 'all-good' and 'all-bad' objects yields to a unified, tension-tolerating internal figure. Flores is the most sustained voice in the retrieved corpus, deploying object constancy as the hinge between developmental arrest and addiction pathology, arguing that the substance-dependent person has failed precisely this integration and recruits chemical agents as substitute regulatory objects. Schore situates object constancy within a neurobiological register, correlating representational development with orbitofrontal maturation and the affective reorganizations of the practicing and rapprochement phases. Bowlby offers a pointed critical counterweight, challenging the concept of 'libidinal object constancy' as theoretically misleading, proposing instead a continuous model of representational growth tied to memory span and recognition. Flores further extends the concept into treatment, tracing how the AA program itself may serve first as transitional object and later as the source of object constancy for the recovering addict. The tensions between classical psychoanalytic, attachment-theoretic, and neurobiological framings of this term constitute its enduring scholarly vitality.

the ability to develop object constancy and have accurate, undistorted mental representations of others is an important developmental task that not everyone is able to accomplish. Mahler sought to understand the source of these distortions and the relationship between developmental arrest and object constancy.
This passage defines object constancy as the developmental capacity to sustain accurate internal representations of others, frames its failure as the central problematic of Mahler's object-relations theory, and links developmental arrest in this domain to clinical pathology.
Flores, Philip J, Group Psychotherapy with Addicted Populations An, 1997thesis
my son had not reacted in fright because he had developed object constancy. His mother could leave the room and, although she was out of sight, she would continue to exist for him because he was developmentally able to carry around a stable mental representation of her in his head.
Through clinical vignette, this passage illustrates object constancy as the achieved ability to maintain a stable internal presence of the attachment figure across physical absence, contrasting it implicitly with the borderline patient's collapse of this capacity.
Flores, Philip J, Group Psychotherapy with Addicted Populations An, 1997thesis
the unfolding of a sense of self-approval, defined as object constancy, can be discerned. What was not completed in childhood may take place later on as the program itself gradually acquires a maternal function, first as a transitional object and later, after individuals have internalized some of the values of the program, as the source of object constancy.
This passage extends object constancy into the domain of addiction recovery, proposing that the AA program can perform a reparative developmental function, moving from transitional object to internalized source of constancy in a trajectory that recapitulates arrested early development.
Flores, Philip J., Addiction as an Attachment Disorder, 2004thesis
The serious shortcomings of the much invoked concept of 'libidinal object constancy' are discussed shortly.
Bowlby signals a sustained critique of the psychoanalytic concept of libidinal object constancy, arguing that the traditional framing misleads by positing an absent-then-present representational capacity rather than a continuously developing one.
Bowlby, John, Loss: Sadness and Depression (Attachment and Loss, Volume III), 1980thesis
In the index to Flores's clinical taxonomy, object constancy appears as the third and culminating stage of Mahler's separation-individuation sequence, situating it structurally as the developmental telos toward which the preceding subphases tend.
Flores, Philip J, Group Psychotherapy with Addicted Populations An, 1997supporting
A second index entry in Flores confirms object constancy as the terminal stage of Mahler's developmental schema within the object-relations theoretical framework applied to addicted populations.

the rapprochement phase may be crucial to the child's ability to internalize conflict and to reconcile clashes between an 'all good' mother and an 'all bad' one.
By detailing the rapprochement crisis — the phase immediately preceding object constancy — this passage illuminates the specific developmental work of integrating split representations that object constancy must resolve.
Flores, Philip J, Group Psychotherapy with Addicted Populations An, 1997supporting
At 18 months the elated mood of the practicing phase is supplanted by the depressive and fearful mood of the rapprochement phase (Mahler et al., 1975). Also at about 18 months, a major discontinuity in the development of mental abilities is observed.
Schore situates the neurobiological and affective transformations of the rapprochement phase — the threshold of object constancy — within a developmental framework linking Mahler's stages to orbitofrontal maturation and representational reorganization.

The group serves as a convoy in the patient's efforts to deal with his or her internalized bad objects.
This passage describes the therapeutic group as a vehicle for working through internalized bad objects, gesturing toward the object-constancy framework without naming it explicitly, as the group facilitates the integration that object constancy requires.

the mental image of the object (mother) is 'created by the child in accord with his or her limited mental capacities'... The patterning of the mental schema we call 'self' and the patterning of the m[ental schema of the object]
Schore, drawing on Horner's object-relations theory, frames the development of internal representations of the mother as constrained by expanding neural capacities, providing the neurobiological substrate for the representational achievement that object constancy names.
