Honing in on the social phenotype in Williams syndrome using multiple measures and multiple raters.

The team looked at kids with Williams syndrome. They asked parents and teachers to fill out social skills forms. Two rating scales showed where the children shined and where they struggled.

Prosocial manners came out near average. Yet both parents and teachers marked big trouble with back-and-forth social play. The same gap showed up at home and at school.

Lough et al. (2016) later asked adults with WS to rate their own social risk. The adults saw less danger than their parents did. Schroeder et al. (2014) watched real-life behavior and learned parent reports predict community social moves better than self reports. Together the three papers say: people with WS often think they are doing fine socially, while outside observers still see clear reciprocity gaps.

Finke et al. (2017) turned the same weakness into a lesson plan. A short social-skills class helped adults learn conversation rules. Their study builds on the 2011 finding by showing the gap can be taught, not just measured.

Lough et al. (2015) compared WS and ASD youth on personal-space violations. Parents of both groups reported frequent intrusions, with WS scoring worst. This turns the broad "social reciprocity" deficit into a concrete target: teach appropriate distance.

You now have a simple profile for Williams syndrome: friendly surface, weak back-and-forth. Trust parent and teacher ratings more than self-report. Pinpoint lessons on turn-taking, personal space, and reading social danger. Start these lessons early and keep them going into adulthood.
