Primary process stands at the structural center of Freudian metapsychology, designating the mode of mental functioning that governs the unconscious: ruled by the pleasure principle, indifferent to contradiction, oriented toward hallucinatory wish-fulfillment, and operating through condensation and displacement rather than logical sequence. The depth-psychology corpus treats the term along several distinct axes. Freud’s own texts locate primary process as the discharge-seeking activity of the first psychical system, set against the inhibitory, reality-testing operations of secondary process — a dyad that shapes all subsequent theorizing about dreaming, symptom-formation, and the therapeutic relationship. Post-Freudian readers, including Kalsched, challenge attempts to quarantine primary process from higher integrative functions, arguing that Jungian psychology demands that even the deepest psychic layer contain both spiritual and instinctual valences simultaneously. Neuroscientific voices, especially Panksepp, recast primary process as subcortical affective consciousness — evolutionarily ancient, phylogenetically shared, and neurologically localizable — contrasting it with the cortically elaborated secondary forms that emerge developmentally and culturally. Alcaro and Carta extend this into a neuro-ethological frame, crediting primary-process dreaming with prospective, adaptive, and creative functions that Freud’s purely retrospective wish-fulfillment model could not accommodate. The tension between primary process as archaic residue and primary process as generative substrate remains the productive fault line running through the entire literature.
Freud calls them the primary process (generally unconscious) and the secondary process (generally preconscious and conscious). Primary process thought is instinctual
Bulkeley provides the canonical Freudian definition, situating primary process as the unconscious, instinctual mode of mental functioning opposed to the reality-oriented secondary process.

The secondary process, however, has abandoned this intention and taken up another in its place — the establishment of a ‘thought identity’… Thinking must concern itself with the connecting paths
Freud defines secondary process by its deviation from primary process: where primary process seeks perceptual identity through hallucinatory discharge, secondary process pursues logical thought-identity via inhibited, circuitous cathexis.

under the dominion of the second system the discharge of excitation is governed by quite different conditions from those in force under the dominion of the first
Freud articulates the foundational structural contrast between the two psychical systems, with primary process characterized by free discharge of excitation and secondary process by inhibition and bound cathexis.

the salutory synthetic organ of the psyche (Freud’s ego, Haule’s Self) which in health organizes and harmonizes (higher, secondary process) the lower chaos but does not participate in its primary process
Kalsched critiques analytic models that install a Freudian hierarchy within Jungian psychology, arguing that Jung’s Self must be understood as ambivalently present within primary process, not merely as its higher-order regulator.

To get at the root of primary-process consciousness empirically, one will surely need to distinguish between the varieties and sources of distinct conscious abilities in different species and the shared neural foundations across species.
Panksepp reframes primary process as a neurobiologically grounded, phylogenetically shared form of affective consciousness whose empirical investigation requires cross-species comparative neuroscience.
, Affective Neuroscience The Foundations of Human and Animal, 1998thesis
the primary process of thinking permits a ‘psychic rehearsal of possibilities’ that unfolds a prospective adaptive function, helping to anticipate possible future events or to find solutions to unresolved problems or conflicts.
Alcaro and Carta reinterpret primary-process dreaming as prospectively adaptive rather than merely regressive, aligning it with REM sleep’s demonstrated enhancement of creativity, insight, and decision-making.
Freud interpreted his clinical data in terms of one active excitatory process being repressed and maintained in the unconscious by an equally active conscious excitatory process. He always spoke in terms of an excitatory flow
Schore critically examines the energic-discharge model underpinning primary process, noting Freud’s lifelong failure to account for independent inhibitory brain processes, a gap that neurobiology subsequently filled.

right-damaged patients tend to completely neglect their diseases (anosognosia), but they often present severe psychiatric symptoms, such as profound melancholia, paranoid ideation or a complete collapse of the ego functions
Alcaro and Carta use neuropsychological evidence from right-hemisphere lesions to ground primary-process object-cathexis in specific cortico-limbic networks, linking its disruption to ego disintegration and psychotic states.

Panksepp invokes hippocampal theta activity during REM as convergent evidence that Freudian and Jungian accounts of dreaming as emotionally driven primary-process activity retain neurobiological plausibility.

William James concluded in 1890 that memory must have at least two different processes: a short-term process, which he called ‘primary memory,’ and a long-term process, which he called ‘secondary memory.’
Kandel documents William James’s distinction between primary and secondary memory, a terminological precursor that, while not equivalent to Freud’s primary process, contextualizes the broader intellectual tradition of dual-process models.
