Blunted affect

Blunted affect is the scientific term describing a lack of emotion
Emotion
Emotion is a complex psychophysiological experience of an individual's state of mind as interacting with biochemical and environmental influences. In humans, emotion fundamentally involves "physiological arousal, expressive behaviors, and conscious experience." Emotion is associated with mood,...

al reactivity on the part of an individual. It is manifest as a failure to express feelings either verbally or non-verbally, even when talking about issues that would normally be expected to engage the emotions. Expressive gestures are rare and there is little animation in facial expression or in vocal inflection.

, or brain damage'. 'The difference between flat and blunted affect is in degree. A person with flat affect has no or nearly no emotional expression. He or she may not react at all to circumstances that usually evoke strong emotions in others. A person with blunted affect, on the other hand, has a significantly reduced intensity in emotional expression'.

 of feelings from events...feelings seem flat instead of being in sharp contact with what is going on'. One study of flat affect in schizophrenia found that 'flat affect was more common in men, and was associated with worse current quality of life' as well as having 'an adverse effect on course of illness'.

The study also reported a 'dissociation between reported experience of emotion and its display' - supporting the suggestion made elsewhere that 'blunted affect, including flattened facial expressiveness and lack of vocal inflection...often disguises an individual's true feelings': thus feelings may merely be unexpressed, rather than totally lacking.

Assessments

In making assessments of such conditions, however, the specialist is cautioned that 'it is important to keep in mind that demonstrative expression can be influenced by cultural differences, medication, or situational factors'; while the layman is warned to beware of applying the criterion lightly to her or 'his friends, otherwise [s]he is likely to make false judgments, in view of the prevalence of schizoid and cyclothymic personalities in our "normal" population, and our [US] tendency to psychological hypochondriasis'.

R. D. Laing in particular stressed that 'such "clinical" categories as schizoid, autistic, "impoverished" affect...all presuppose that there are reliable, valid impersonal criteria for making attributions about the other person's relation to his actions. There are no such reliable or valid criteria'.

Affective flattening

Affective flattening is a general category which includes diminishment of, or absence of, emotional expressiveness. It is sometimes inappropriately equated with blunted or restricted affect. "Blunted" is affect that is present but only with minimal degrees of emotions evident. "Restriction" is a holding back as in alexithymia

. "Restricted" is not as severe as in flattened or blunted affect.

Constricted affect is an affect type that represents mild reduction in the range and intensity of emotional expression. If the client is consistently euphoric and all intensity is congruent but is unaffected by content, this would be still considered constricted to a euphoric affect.

Labile affect refers to the pathological expression of laughter, crying, or smiling. It is also known as "Pseudobulbar Affect", "Emotional Lability", "Pathological Laughter and Crying", or, historically, "Emotional Incontinence". An individual may find themselves laughing uncontrollably at something that is only moderately funny, being unable to stop themselves for several minutes.

Qualities describing the affective response include:
  • concordance (expressed emotion seems to fit what patient is saying, doing) appropriateness, responsiveness (expressed emotion sensibly follows from the precipitating stimuli)
  • full range/stable (normal variation of emotions during exam)
  • restricted, constricted range (limited variability of emotion during exam)
  • labile (type or intensity shifts suddenly, rapidly)
  • blunted (few emotions expressed, low intensity)
  • flat (affect is even less intense than blunted; patient may appear inanimate)
  • exaggerated intensity

Related symptoms

Blunted affect is very similar to anhedonia, the decrease or cessation of all feelings of pleasure (which thus affects enjoyment, happiness, fun, interest, and satisfaction). In the case of anhedonia, emotions relating to pleasure will not be expressed as much or at all because they are literally not experienced or are decreased. Both blunted affect and anhedonia are considered negative symptoms of schizophrenia
