Overview of selected basic research in autism.
Autism is likely many body roads under one name, so keep behavior tools sharp while biomarkers mature.
01Research in Context
What this study did
Yelton (1979) looked back at early lab work on kids with autism.
The author asked: do these children share one body problem or many?
The paper pulled together small studies on things like eye tracking after spinning and blood serotonin levels.
What they found
The review said autism is probably a mix of separate body types.
It warned that behavior labels alone hide these groups.
To move forward, we need clear body markers, not just checklists.
How this fits with other research
Szatmari (1992) took the idea further and mapped three behavior subtypes: Asperger, low-IQ atypical, high-IQ atypical.
Dubuque (2015) later pushed back hard, saying current biomarker tests are useless and can hurt families.
This looks like a fight, but it is really about timing: Yelton (1979) asked for discovery, Dubuque (2015) said the tools are not ready yet.
Rutter (2013) sums it up: the field must rethink autism as new facts come in, just as Yelton (1979) first urged.
Why it matters
When you assess a child today, remember the label "autism" may cover many body routes.
Keep watching new biomarker work, but stay with solid behavior tools for now.
Use clear subject details in your own data so future reviews can sort kids better.

03Original abstract
Basic research in autism is reviewed. There is mounting indication, but as yet inconclusive evidence, of unique physiologic disturbances etiologically related to autism. Additionally there is indication that some of the physiologic disturbances found in autistic children are also present in children with other developmental disorders. Children called autistic probably represent a complex of clinically similar manifestations in a variety of different subgroups of children, each subgroup representing a basically different physiologic disturbance. However, the possibility remains that there is only one basic disturbance that in varying degrees affects many body systems and thus manifests in a variety of overlapping syndromes. Objective markers are needed so as to allow the demarcation of subgroups of autistic children for further study. Possible markers may be decreased duration of postrotatory nystagmus, auditory evoked response deviations, lymphocytic hyporesponsivity, increased blood platelet serotonin efflux, and/or the presence of urinary DMT or bufotenin.
