KembaraXtra-Psychology - autocorrelation
Autocorrelation is the correlation between values in a time series and the same series shifted by a fixed lag. For example, daily migraine ratings can be correlated with ratings from one day earlier (first-order autocorrelation), and such autocorrelations tend to be positive when today’s score predicts tomorrow’s. Correlations with scores two days apart form second-order autocorrelation, and so on; it relates to autoregression and correlograms.

KembaraXtra-Psychology - autochthonous
Autochthonous means originating from within rather than from outside stimulation, applied both to bodily functions that are self-generated (like heartbeat) and to psychological forms (such as an autochthonous Gestalt produced by the perceiver rather than inherent in the stimulus).

KembaraXtra-Psychology - autism spectrum disorder
Autism spectrum disorder (ASD) is a DSM-5 neurodevelopmental disorder defined by persistent impairments in social interaction and communication plus restricted, repetitive patterns of behaviour, interests, and activities. Symptoms begin early, though they may become more obvious later as social demands increase; they must cause clinically significant impairment and must not be better explained by intellectual disability or general developmental delay. Features may include limited emotional responsiveness, poor reciprocity, difficulty forming peer relationships, delayed or absent speech, stereotyped/idiosyncratic language and nonverbal behaviour (including gaze aversion), insistence on sameness, and ritualized mannerisms. DSM-5 reports prevalence around 1% in both child and adult samples in the US and other countries. The condition was described by Leo Kanner (1894–1981) in 1943 and Hans Asperger (1906–80) in 1944 and has also been called autistic disorder, childhood autism, infantile autism, and Kanner’s syndrome; it relates to topics such as theory of mind and mirror neurons and is compared with ADHD, Rett’s disorder, schizophrenia, and selective mutism.

KembaraXtra-Psychology - autoregression
Autoregression is a time-series property where each value can be expressed as a linear function of a preceding value (first-order) or multiple preceding values (higher-order). Even first-order autoregression gives the series “memory” because each value becomes correlated with earlier ones. It relates to ARIMA models, autocorrelation, and correlograms.

An autoreceptor is a receptor for a neurotransmitter located on the same neuron that releases that neurotransmitter—often on presynaptic membranes—helping monitor and regulate synthesis and release levels.

Autoradiography is a method for visualizing where radioactively labelled molecules are located in tissue by exposing photographic material to radiation emitted from the specimen, producing an image of distribution patterns.
