Face and object discrimination in autism, and relationship to IQ and age.

Whitehouse et al. (2014) tested how well teens with autism can tell faces apart and how well they can tell objects apart.

They also looked at whether IQ or age predicted better scores on each task.

The study used a quasi-experimental design with middle- and high-school students diagnosed with ASD.

Face scores were slightly lower than typical, but the gap was not big enough to be significant.

Object scores, however, were clearly higher than typical.

Higher IQ helped face scores more than age did; age helped object scores more than IQ did.

Faja et al. (2009) saw clear face-config deficits in adults with ASD, yet this teen sample did not. The difference is likely age: adults show the gap more than teens.

Bradshaw et al. (2011) found preschoolers with ASD excelled at complex nonsocial patterns, matching the teen object boost seen here.

Anthony et al. (2020) later showed autistic kids looked at faces and objects equally, linking poorer face recognition to less looking. Together the papers suggest the face weakness is real but small, while object strength stays strong across ages.

When you assess visual skills, expect autistic learners to shine at object tasks and to show only mild face weaknesses. Use their object strength to teach matching and categorization first. If you need face work, check IQ: higher IQ students may need fewer trials, while lower IQ students may need extra practice and simpler stimuli.
