Recognition memory, self-other source memory, and theory-of-mind in children with autism spectrum disorder.

The team tested kids with autism on three things. First, could they recognize a picture they had seen before? Second, could they remember who did an action — themselves or the experimenter? Third, how did they score on simple theory-of-mind questions.

Each child sat at a table and handled objects. Later the child pointed to photos and answered “Did you do this or did I?” The testers also gave false-belief tasks to check social understanding.

Recognition memory was fine. Kids with autism picked the right photos as often as typical kids.

Source memory was not fine. They often forgot who had performed the action. Oddly, in typical kids better theory-of-mind went hand-in-hand with better source memory, but in autism the two scores did not link up.

Yamamoto et al. (2018) later saw the same pattern in adults: enacted actions boosted memory for everyone, yet adults with autism still mixed up who did what. This tells us the problem is lifelong, not just a delay.

Wuyun et al. (2020) found a bright spot. When kids with autism actually moved the object themselves, or clearly saw the experimenter move it, their self-memory jumped to typical levels. So action cues can patch the gap Lancioni et al. (2009) first measured.

Lancioni et al. (2009) also ran a delayed self-recognition task in the same year and saw no autism deficit. That looks like a clash — how can kids recognize their own face in a mirror yet forget who performed an action? The tasks differ: mirror self-recognition needs only “me,” while source memory needs “me versus you.” The second job is harder and stays weak in autism.

When you ask a learner, “Did you put the toy away or did I?” you are checking source memory. Expect wrong answers even if the child can recall the toy itself. Add clear action tags — have the child hold the item, wear a glove, or watch you do it — to sharpen the self-other line. This small tweak can cut confusion and build accurate self-monitoring, a skill that feeds into social stories and self-management plans.
