Preference for Geometric Patterns Early in Life as a Risk Factor for Autism
Open accessAbstract
CONTEXT: Early identification efforts are essential for the early treatment of the symptoms of autism but can only occur if robust risk factors are found. Children with autism often engage in repetitive behaviors and anecdotally prefer to visually examine geometric repetition, such as the moving blade of a fan or the spinning of a car wheel. The extent to which a preference for looking at geometric repetition is an early risk factor for autism has yet to be examined. OBJECTIVES: To determine if toddlers with an autism spectrum disorder (ASD) aged 14 to 42 months prefer to visually examine dynamic geometric images more than social images and to determine if visual fixation patterns can correctly classify a toddler as having an ASD. DESIGN: Toddlers were presented with a 1-minute movie depicting moving geometric patterns on 1 side of a video monitor and children in high action, such as dancing or doing yoga, on the other. Using this preferential looking paradigm, total fixation duration and the number of saccades within each movie type were examined using eye tracking technology. SETTING: University of California, San Diego Autism Center of Excellence. PARTICIPANTS: One hundred ten toddlers participated in final analyses (37 with an ASD, 22 with developmental delay, and 51 typical developing toddlers). MAIN OUTCOME MEASURE: Total fixation time within the geometric patterns or social images and the number of saccades were compared between diagnostic groups. RESULTS: Overall, toddlers with an ASD as young as 14 months spent significantly more time fixating on dynamic geometric images than other diagnostic groups. If a toddler spent more than 69% of his or her time fixating on geometric patterns, then the positive predictive value for accurately classifying that toddler as having an ASD was 100%. CONCLUSION: A preference for geometric patterns early in life may be a novel and easily detectable early signature of infants and toddlers at risk for autism.

§ Preference for Geometric Patterns Early in Life as a Risk Factor for Autism > COMMENT

It may state two separate claims as one.
The paper relies on this without support.
The paper assumes that the question of whether a preference for geometric repetition is an early autism risk factor has not yet been examined.
“The extent to which a preference for looking at geometric repetition is an early risk factor for autism has yet to be examined.”
“The early developmental profile of unusual preferences for visual repetition in autism is largely unknown and unexplored.”
The paper relies on this without support.
The paper assumes, on anecdotal grounds, that children with autism often prefer to attend to visual repetition.
“Many children with autism engage in a variety of repetitive behaviors 26 and, anecdotally, often prefer to attend to visual repetition, such as the moving blade of a fan or the spinning of a car wheel.”
The paper relies on this without support.
The paper assumes that a prior study found that eye gaze patterns at 6 months did not predict later diagnostic outcome.
“examined the clinical outcome of these subjects and found that, contrary to their expectations, eye gaze patterns at 6 months did not predict diagnostic outcome.”
The paper relies on this without support.
The geometric preference seen in a subgroup of ASD toddlers at 14-42 months is present earlier in life and is not caused by the ASD diagnosis.
“some infants at risk for an ASD begin life with an unusual preference for geometric repetition.”
The paper relies on this without support.
The exclusion of about 20% of the sample due to poor compliance did not substantially bias the results.
“approximately 20% of the overall sample was dropped from analyses because of poor compliance during testing, with the impact of such exclusion unknown.”
The paper relies on this without support.
The one-third of the sample that completed test-retest reliability is representative of the whole sample.
“only one-third of the overall sample participated in test-retest reliability.”

In the paper
§ Preference for Geometric Patterns Early in Life as a Risk Factor for Autism > DEPENDENT VARIABLES AND STATISTICAL ANALYSES
“There was a significant difference in total viewing time between groups (F 3,106 =3.2; P=.02; mean viewing time: ASD, 49.4 seconds; TD, 53.7 seconds; and DD, 48.1 seconds).”
§ Preference for Geometric Patterns Early in Life as a Risk Factor for Autism > DEPENDENT VARIABLES AND STATISTICAL ANALYSES
“To compare percentage of fixation time within DGI between the 3 diagnostic groups, a 1-way analysis of variance was performed (diagnostic group [3 levels] × percentage of DGI fixation time [1 level]).”

“The significance level in contrast to social responders with an ASD was P = .02,but this did not meet the Bonferroni correction threshold of less than .0125(Figure 5).”
§ Preference for Geometric Patterns Early in Life as a Risk Factor for Autism > 59 -61
“When viewing social images, geometric responders with an ASD had significantly more saccades than all other groups.”
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-05, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-05 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
