The Seba library treats Flattened Affect in 9 passages, across 6 authors (including Clarissa Pinkola Estés, Ph D, Bleuler, Eugen, Gallagher, Shaun).
Vasalisa began with what we might call a flattened-out mundane personality.
Estés names flattened-out personality as the archetypal starting condition of a soul estranged from the instinctual wild nature, requiring the transformative descent into liminal powers to recover vitality.

She seems flattened out, filled with ideas perhaps, but deeply anemic and more and more unable to act upon them.
Estés frames the flattening of creative energy as a consequence of deep soul-wounding — the decimation of soulful life-force — distinct from mere procrastination or surface laziness.

constellations of ideas which are not well thought out are easily accompanied by only a moderate or only a very small amount of feeling-tone.
Bleuler traces the flattening of affective response to the severed connection between ideational content and its full associative context, laying the psychiatric groundwork for understanding inappropriate or absent emotional tone in schizophrenia.

it is important to distinguish between overt emotional states that may be the result of positive symptoms, and prenoetic disruptions of affective experience that may not always manifest themselves in emotional attitudes.
Gallagher differentiates visible emotional flatness from a deeper, prenoetic disruption of affective experience, arguing that the absence of overt distress in schizophrenic patients does not mean affective life is intact at the constitutive level.
, How the Body Shapes the Mind, 2005thesis
This affective tonality is tacit in the sense that I am not usua… This is the feeling of identity, of being the perspectival origin of one’s own experience.
Gallagher identifies the tacit affective tonality underlying self-identity as the foundational stratum whose disruption produces phenomena clinically observed as flattened or disturbed affect.

foggy, ‘spaced out’ states of hypoarousal, both of which interfered with daily life activities associated with marriage, work, play, and rearing children.
Ogden frames hypoarousal and the dissociative ‘spaced out’ state as the somatic-trauma correlate of flattened affect, positioning it as one pole of traumatic dysregulation alongside hyperarousal.

sad speech exhibits a more monotone prosody (narrow pitch movements), mumbled articulation, breathier voice, and a darker timbre or tone color.
Lench documents the acoustic and facial signatures of affective flattening in sadness — monotone prosody, relaxed musculature, flattened cheeks — as low-arousal physiological expressions with functional behavioral consequences.

Relaxation of the zygomatic muscles tends to flatten the cheeks, and relaxation of the mouth tends to cause the chin to descend.
Lench offers a somatic account of affective flattening at the muscular level, linking the visible ‘long face’ of sadness to reduced physiological arousal rather than absent emotion.

Insecure Attachment, Affect Dysregulation, and Developmental Psychopathology is Operationally Defined as a Limitation of Adaptive Stress-Regulating Capacities.
Schore situates affect dysregulation — including depressive and muted affective states — within a developmental neurobiological framework tied to impaired orbitofrontal maturation and early relational failure.
