Elephants in Pyjamas: Testing the Weak Central Coherence Account of Autism Spectrum Disorders Using a Syntactic Disambiguation Task.

Riches et al. (2016) · Journal of autism and developmental disorders 2016
★ The Verdict

Weak central coherence theory gains no support from adolescent sentence-comprehension data—processing speed did not differ by ASD status.

01Research in Context

01

What this study did

Riches et al. (2016) asked teens to read tricky sentences. One sentence said, “The elephants in pajamas washed the keeper.”

The team timed how fast kids with and without autism picked the silly meaning. They wanted to see if autism makes people miss the big picture.

02

What they found

Both groups spotted the joke just as fast. Kids with autism did not lag behind.

The result says weak central coherence is not showing up in teen language tasks.

03

How this fits with other research

Kaland et al. (2007) ran a near-copy test years earlier. They used picture puzzles, not sentences, and also found no ASD speed edge. Together the two papers form a clean replication across verbal and visuo-spatial jobs.

Ferraro (2016) crunched 32 studies and found no general reaction-time slowing in autism. That meta-score backs the new null RT result.

Koh et al. (2012) looks like a clash at first. They saw stronger field-independence in English kids with autism, a sign of weak coherence. But the same team found no effect in Singaporean kids. Culture, not autism, drove the difference. So the papers do not truly disagree; they show the effect vanishes outside Western samples.

04

Why it matters

Stop blaming slow or odd answers on weak central coherence. If a teen with autism hesitates on language tasks, look at vocabulary, syntax, or motivation instead. Use clear sentences, not extra context cues, to boost understanding.

03Original abstract

According to the weak central coherence (CC) account individuals with autism spectrum disorders (ASD) exhibit enhanced local processing and weak part-whole integration. CC was investigated in the verbal domain. Adolescents, recruited using a 2 (ASD status) by 2 (language impairment status) design, completed an aural forced choice comprehension task involving syntactically ambiguous sentences. Half the picture targets depicted the least plausible interpretation, resulting in longer RTs across groups. These were assumed to reflect local processing. There was no ASD by plausibility interaction and consequently little evidence for weak CC in the verbal domain when conceptualised as enhanced local processing. Furthermore, there was little evidence that the processing of syntactically ambiguous sentences differed as a function of ASD or language-impairment status.
