Curve

Within the depth-psychology corpus, ‘curve’ operates on at least three distinct registers that intersect without collapsing into one another. In McGilchrist’s neuropsychological phenomenology, curvature is explicitly valorised as the signature of right-hemisphere cognition: the flowing, non-linear arc that reconciles opposites and admits indirection is contrasted against the straight line, emblem of left-hemisphere sequential processing and its attendant march toward the abyss. This is not mere aesthetics but an ontological claim — that the curved form discloses a living world more faithfully than the rectilinear. In Jung’s early experimental work, ‘curve’ appears as a technical instrument of psychophysical research: the galvanometer and pneumograph curves serve as indices of unconscious complexes, charting the body’s involuntary testimony to buried affect. Here the curve is epistemic — a trace that consciousness cannot falsify. A third, clinical register emerges in Ogden’s sensorimotor psychotherapy, where the arousal curve maps the patient’s trajectory through the window of tolerance, providing a navigational metaphor for somatic regulation. Ulanov introduces the mathematical curve — the bifurcating parabola of chaotic dynamics — as a model for psychological complexity. Schore employs behavioral curves to contrast attuned and misattuned dyadic transactions. The term thus traverses aesthetics, neuropsychology, psychophysiology, somatic therapy, and developmental theory, carrying in each domain a common deeper suggestion: that living process is non-linear, and that fidelity to its actual shape is both epistemological virtue and therapeutic necessity.

McGilchrist advances curvature as the defining formal quality of right-hemisphere cognition, contrasting it with rectilinear motion as the signature of left-hemisphere linearity and literalism.

Parallel passage confirming McGilchrist’s sustained thesis that curvature encodes a mode of knowing irreducible to, and superior in certain domains to, linear analytical approaches.

the emotions of the unconscious, roused up by questions or words that strike into the buried complexes of the soul, reveal themselves in the galvanometer curve, while the pneumographic curve is comparatively unaffected.

Woodman, citing Jung, establishes the galvanometer curve as the involuntary somatic register of unconscious complexes, contrasting it with respiratory curves that remain amenable to conscious control.

The very circularity of things as they really are, rather than as the left hemisphere conceives them, might be a reason for hope. Linear progression versus circular

McGilchrist argues that the curved, circular shape of actual reality resists the left hemisphere’s linear model of progress, offering this ontological curvature as grounds for hope against reductive thinking.

the emotions of the unconscious, roused up by questions or words that strike into the buried complexes of the soul, reveal themselves in the galvanometer curve, while the pneumographic curve is comparatively unaffected. Respiration is an instrument of consciousness. You can control it voluntarily while you cannot control the galvanometer curve.

Jung distinguishes the galvanometer curve as an uncontrollable index of unconscious affect from the respiratory curve, which consciousness can regulate, establishing the curve as a site of involuntary psychic disclosure.

Ogden employs the arousal curve as a clinical navigational schema in sensorimotor psychotherapy, charting the patient’s movement through cycles of sympathetic activation and return to the window of tolerance.

Viewed geometrically, graphing the equation at this point generates a curve that splits into two curves, like a parabola lying on its side with the apex at the bifurcation point.

Ulanov applies chaotic-systems mathematics to psychological dynamics, using the bifurcating parabolic curve as a model for the period-doubling cascades that emerge from mutual inhibition equations.

The latency time and the time required for the curve to reach its maximum height bear no constant relation to the height of the galvanic curve.

Jung notes that the temporal parameters of the galvanometric curve do not predict its amplitude, complicating any simple causal account of affective arousal and its physiological trace.

Such a curve was clearly shown in the case of a well-educated physician, with a considerable power of self-analysis, who could not remember any affective thought that had occurred to him during the period.

Jung presents a galvanometric curve as evidence of unconscious emotional activity occurring entirely below the threshold of conscious recall, even in a subject possessing high self-analytic capacity.

normal respiratory curve inconstant, subject to variations due to age, temperament, perseveration of affect, reactions from the affect, embarrassment from the experiment, undue interest in the procedure, etc.

Jung’s collaborators identify the respiratory curve as a psychophysiologically unstable measure, its variability reflecting the complex interplay of temperament, perseverating affect, and situational factors.

We observe here one of the numerous instances where the pneumographic curve and the reaction-time show evident disturbances, while the galvanic curve is unaffected.

Jung demonstrates a dissociation between the pneumographic and galvanometric curves, arguing that each registers a distinct dimension of psychic processing — the one intellectual perseveration, the other acute affect.

Jung organises reaction-time data into plotted curves as a methodological convenience, using the curve here as a representational rather than theoretical device.
