DISCLAIMER: Conditions explored do not reflect any official diagnosis on yours truly. The official tag I've been labelled with is Bipolar Disorder with Rapid Cycling.
Now, the following are just "exploratory" and are not intended to describe my own behaviors and thoughts, although, there will most certainly be some definitions which do, indeed, align with some of my quirks and strengths.
Schizoid personality disorder:
(/ˈskɪtsɔɪd, ˈskɪdzɔɪd/, often abbreviated as SPD or SzPD) is a personality disorder characterized by a lack of interest in social relationships, a tendency toward a solitary or sheltered lifestyle, secretiveness, emotional coldness, detachment and apathy. Affected individuals may be unable to form intimate attachments to others and simultaneously possess a rich and elaborate but exclusively internal fantasy world. Other associated features include
stilted speech, a lack of deriving enjoyment from most activities, feeling as though one is an "observer" rather than a participant in life, an inability to tolerate emotional expectations of others, apparent indifference when praised or criticized, a degree of asexuality and idiosyncratic moral or political beliefs. Symptoms typically start in late childhood or adolescence.
stilted speech:
In psychiatry, stilted speech or pedantic speech is communication characterized by situationally-inappropriate formality. This formality can be expressed both through abnormal prosody as well as speech content that is "inappropriately pompous, legalistic, philosophical, or quaint". Often, such speech can act as evidence for autism spectrum disorder or a thought disorder, a common symptom in schizophrenia or schizotypal personality disorder.
To diagnose stilted speech, researchers have previously looked for the following characteristics:
1. speech conveying more information than necessary
2. vocabulary and grammar expected from formal writing rather than conversational speech
3. unneeded repetition or corrections
While literal and long-winded word content is often the most identifiable feature of stilted speech, such speech often displays irregular prosody, especially in resonance. Often, the loudness, pitch, rate, and nasality of pedantic speech vary from normal speech, resulting in the perception of pedantic or stilted speaking. For example, overly loud or high-pitched speech can come across to listeners as overly forceful while slow or nasal speech creates an impression of condescension.
