What is a Dissocial Spectrum Disorder?
Well, in my view, that encompasses individuals with flat-effect, shallow-affect, schizoid traits, or primary psychopathy; sometimes low-empathy autism.
That is, cases where affective empathy is nescient, but fails to produce debilitating antisocial behaviours or misconduct. Few traits could still be present, but in mundane doses that do not take main concern. Meaning a dissocial could also have ASPD, but not intrinsically.
The main issues in DSSD portend to interpersonal deficits that inhibit social behaviour, yet does not cause outgoing hostility or sadism, but an indifference to others that can present with callous-unemotional traits or a flatly "serious" countenance, though not always. Some dissocials can be engaging, charming, socially polite by utilizing cognitive empathy to read others and filter behaviours accordingly to compensate in social contexts thus, appear quite "normal" (also refered to as 'masking') if only a bit difficult to really know.
This distance can cause dejection, suspicion. Indifference may be read sometimes as hostile, as it can advertently or inadvertently cause negligence to an emotional need one may not realize someone has.
Dissocials are self-interested, not necessarily in a way that is narcissistic or intends to use others to gain, but in that we are goal-oriented, resilient, and self-reliant which can create a tunnel vision. Stereotypically, we can be "workaholics." We don't really think about others as a rule; not in a cruel way, in an absent-minded way that we don't pay attention unless they are in the way or have made themselves prominent. Hurt is the byproduct of a lack of attention in many cases, not the focus or intent.
Though quite possible, dissocials are not necessarily people shy; in my experience, due to a lessened amount of psychological fear or anxiety I can be a rather graceful communicator if need be but will always prefer "introverted" activities that can be done alone, as our need for people is greatly diminished due to impaired limbic activity (often due to early prolonged traumas) that make it so we do not experience the same fulfilling resonation and connection other people might around eachother. It often produces little to no serotonin at all. That means any activity involving others is mostly extraneous and for social etiquette reasons.
Scientific study shows people begin to lose it without human contact for a stretch of time and will naturally seek the presence of others. Someone with a DSSD won't experience this same compulsion so strongly, if not at all.
Primary psychopathy, characterized by an absence of guilt, lessened anxiety, callousness, shallow affect, extreme self-preservation/self-motivated behaviour, and near complete detachment with fine emotional control, is a condition on the far or "severe" end of this spectrum.
