Emotional modulation of perception in Asperger's syndrome.
Emotional events don't automatically capture attention for clients with Asperger's; consciously highlight important stimuli for them.
01Research in Context
What this study did
Williams et al. (2008) ran an attentional blink task with adults who have Asperger's. They flashed pictures on a screen. Some pictures carried strong emotion. Others were neutral.
The team asked: do emotional pictures grab attention faster in people with Asperger's, like they do in typical adults? They measured how many pictures each person spotted.
What they found
Adults with Asperger's did not get the usual boost for emotional pictures. Their perception stayed flat. The study calls this an amygdala-modulation failure.
In plain words, exciting pictures did not pop out for them. They missed more targets than controls did.
How this fits with other research
Antaki et al. (2008) saw the same flat line with memory. Their Asperger group recalled no more emotional pictures than neutral ones. Together, the two papers show the problem sits in both seeing and remembering emotional events.
Doi et al. (2013) conceptually replicated the finding. They used faces and voices instead of attentional blinks. Again, adults with Asperger's scored lower on angry and sad emotions, especially at mild levels.
Kaufman et al. (2010) extended the idea downward to the startle reflex. Kids with broader ASD showed odd early jump responses to emotional sounds. The same amygdala-modulation failure now shows up in eye blinks, heart beats, and memory tests.
Why it matters
If emotional cues do not auto-highlight, you must do the highlighting. Tell the client why a picture, word, or face is important before you ask them to work with it. Use clear labels, extra trials, and reinforcement for attending. Check that emotional social stories actually stick by testing recall the next day.

03Original abstract
Using an attentional blink paradigm, we show that the typical enhancement of perception for emotionally arousing events is significantly reduced in Asperger's syndrome (AS) at short inter-target intervals. Control experiments demonstrate that this finding cannot be attributed to differences in the perceived arousal of the stimuli, or to a global impairment affecting any type of modulation of perceptual encoding. Because a functioning amygdala is critical for emotional modulation of the attentional blink, the findings support a role for the amygdala in the pathophysiology of AS. More specifically, they suggest there is a fundamental failure of the amygdala to modulate processing in cortex, a concept at the heart of some recent theories of amygdala involvement in the aetiology of autistic-spectrum disorders.
