Sympathy for Others and the Old Squash and Stretch, Aka Sympathy for the Objects

Here we go again. It's complicated, but not really.
The research is about the ability of 10-month old infants to feel empathy for others. That's nice, and not very surprising. What particularly interests me about the research, however, is the way it was conducted. The infants were shown videos involving simple geometric figures, not people. That is, the stimuli were like those used in the famous experiment where Fritz Heider and Marianne Simmel showed simple animated figures to Smith undergraduates who them willing interpreted those simple shapes and living creatures in purposeful interaction with one another.
Here's a summary of the current research in Medical Express:

Infants express non-verbal sympathy for others in distress
Infants as young as ten months old express sympathy for others in distress in non-verbal ways, according to research published June 12 in the open access journal PLOS ONE by Yasuhiro Kanakogi and colleagues from Kyoto University and Toyohashi University of Technology, Japan.
Infants at this age are known to assign goals and intentions to geometric figures; hence the researchers used a series of animated sequences to test infants' responses to aggression. In their experiments, researchers showed infants an aggressive 'social interaction' between a blue ball that attacked and violently crushed a yellow cube and found that the babies preferentially reached for the victim rather than the aggressor. Infants' behavior remained consistent when the roles of the shapes were reversed and when a neutral, non-aggressive shape was introduced in the video, suggesting that their preference for the victim was not out of fear of the aggressive shape.
Based on these observations, the authors conclude, "Ten-month olds not only evaluate the roles of victims and aggressors in interactions but also show rudimentary sympathy toward others in distress based on that evaluation. This simple preference may function as a foundation for full-fledged sympathetic behavior later on."

You'll find the video there. The squash and stretch (a classic animation technique) comes at the very end.
