Stimulus overselectivity four decades later: a review of the literature and its implications for current research in autism spectrum disorder.

Ploog (2010) read every paper on stimulus overselectivity since 1970.

The author pulled out patterns, causes, and fixes for kids with autism.

Kids with autism often lock onto one part of a cue and miss the rest.

The review says this narrow focus still blocks learning today.

It lists ABA tricks—like training many examples and shaping attention—that can widen stimulus control.

Vassos et al. (2016) seems to disagree. When kids are matched for IQ, autism, Down syndrome, and typical groups all show the same level of overselectivity. The clash fades once you see Ploog (2010) looked at unmatched autism samples, while Vassos et al. (2016) controlled IQ.

Cox et al. (2015) updates the story. Only 19 % of kids with autism now show overselectivity, down from older highs. The drop hints that today’s early ABA programs already use the tactics Ploog (2010) recommends.

McAleer et al. (2011) adds that overselectivity can be taught. Adults trained with super-complex cues later act overselective on new tasks. The finding supports O’s call to start with simple stimuli and build up.

Check your learner’s stimulus control early. If they only notice color and ignore shape, add differential observing prompts like Farmer-Dougan et al. (1999) and rotate many examples. Keep tasks simple at first; complexity trains overselectivity, as McAleer et al. (2011) shows. These small tweaks turn broad reviews into faster skill gains.
