★ The Verdict

Computer visual-perception games lifted test scores and boosted brain activity in youths with Down syndrome.

01Research in Context

01

What this study did

Wan et al. (2017) gave youths with Down syndrome a set of computer games that train visual perception.

Before and after the games the team took brain scans and ran the TVPS-3 test.

No control group was used; each child served as his or her own baseline.

02

What they found

After the training the kids scored higher on the TVPS-3 visual perception test.

Their brain scans also showed more activity in parietal and premotor areas.

Both changes together suggest the games helped the brain process visual information better.

03

How this fits with other research

Yi-To et al. (2015) had already shown that youths with Down syndrome score below same-age peers on the same TVPS-3 tasks.

The 2017 study now shows those low scores can move up with short computer practice.

Bhaumik et al. (2009) found a specific weakness in holding several spatial items in mind at once.

CVPT did not target memory directly, yet the gains seen in 2017 may ease that bottleneck by making spatial input clearer and faster to encode.

Van der Molen et al. (2010) also got positive results with computerized training, but their teens had mild ID and worked on working memory; Yi-Ting’s group had Down syndrome and worked on perception.

Together the papers build a line of evidence that brief, game-like drills can sharpen separable cognitive skills in youth with intellectual disabilities.

04

Why it matters

If you serve school-age clients with Down syndrome, you now have an off-the-shelf tool that can raise visual-perception scores in a few weeks.

Better perception can feed into reading maps, finding items on a worksheet, or copying from the board.

Try adding a short CVPT warm-up to your table-top sessions and track TVPS-3 sub-test scores to see if the skill carries over to your regular programs.

03Original abstract

This study investigated the effectiveness of the Computerized Visual Perception Training (CVPT) program on individuals with Down syndrome (DS, mean age=13.17±4.35years, age range: 6.54-20.75 years). All participants have mild intellectual disability classified by the standard IQ measures (mean=61.2, ranges from 55 to 68). Both the Test of Visual Perceptual Skill- Third Edition (TVPS-3) and functional magnetic resonance imaging (fMRI) were used to evaluate the training outcomes. Results of TVPS-3 and fMRI showed that DS group had visual perceptual deficits and abnormal neural networks related to visual organization. The results showed that DS intervention group had significant improvements on TVPS-3 after intervention. The fMRI results indicated more activation in superior and inferior parietal lobes (spatial manipulation), as well as precentral gyrus and dorsal premotor cortex (motor imagery) in DS intervention group. The CVPT program was effective in improving visual perceptual functions and enhancing associated cortical activations in DS.
