Causes of Autism
Biological Causes: Biological defects in components critical for VP and PB to work together result into affecting overall functioning of DOS. Especially, defect in corpus callosum (the bundle of nerves connecting both hemispheres) affects communication between VP and LB, which affects development of personal B-ROM, besides affecting development of CB-ROMs, as they are made using personal B-ROM
(more under title Building CB-ROMs).
In detail: Perception, imagination, intuition, motivation, etc. use complex procedures of parallelly retrieving, processing and storing past and/or future data multiple times in LB (i.e. implicit usage of past and/or future data) and VP (i.e. explicit usage of past and/or future data) using corpus callosum, which plays a major role in building personal B-ROM and CB-ROMs. If there is biological defect in components critical for VP and
LB to work together, especially corpus callosum, which affects communication between VP and LB, all such phenomena get affected, resulting into inferior building of personal B-ROM and CB-ROMs.
Based on the above, one can conclude that all autistics possess weak personal B-ROMs, and thus, have weak personalities
(more under title B-ROM and Personality), which is not true. The reason for the same is difference between inherited strength of building CB-ROMs, which is weak
(as mentioned under title Hereditary Causes) and personal B-ROM, which is relatively strong due to its dependency for the goals of survival and reproduction (as functioning of personal B-ROM is more important for survival and reproduction than having CB-ROMs). As a result of this, autistics' personalities range from normal to weak, which is based on their inherited strength of building personal B-ROMs.
