So infants perceive unfairness when one animal received any amount and the other received absolute nothing. But they are unable to perceive unfairness if both receive SOMETHING

It is interesting that the infants may be trying to tell the agent something about their false belief. Does this suggest that the infants perceive the false belief to be so important that it is worthy of informing the agent about?

I don't know much about infant memory, but this seems like a lot of information to expect a baby to care about and remember for long enough to apply to the second part of the condition.

1. This figure is confusing to me because it is quite overwhelming to look at
2. This is the longest figure caption I have ever seen

Since these researchers found evidence of belief in infants as young as 15 months, how would they explain the research that suggests that children as old as preschool age cannot understand beliefs??

The method sounds similar to the method employed in the intention experiment, where the locations were changed and looking time increased when the hand reached for a new item rather than a new path.

Can babies tell that both things are possible to do at once?

I am very curious to see a video of these experimental procedures!

Does this tells us that some infants are able to distinguish intention by 5 months, but others aren't?

So "Grasp" is intention and "Back-of-hand" is no intention?

Why was the way the hand was facing (palm up or down) changed? The hand could still fall while face down. It may be beneficial to add another level of palm up or down to test this.

Why are infants more interested in changes in vowel rather than changes in pitch or tone? We use to infant-directed speech to sustain their attention because infants enjoy these tonal and pitch changes, so it makes more sense to me that they would be more interested in this.

This is interesting to me - so many of the other studies we have analyzed have presented sound from videos or recording out loud over a speaker. Do the babies get irritated with something in their ear? It seems unnatural

I wonder what other ways there are to test infants' knowledge of different words, besides head turns. Would there be a way to use looking time? Perhaps if a video of the same persons saying different words "kixm/qixm", infants might look longer than if they said the same word.

Did some infants really learn the association after only two trials?

Why do some infants respond with increased cortisol and some with decreased cortisol?

How exactly does time of day affect stress levels? This section tells me that there was a significant difference between stress 1 and control, and stress 1 and stress 2, but not how the time of day affected stress levels.

Does this mean that other studies may have used infants who were not "normal alert"?

How did Piaget come up with this number? Was it tested or a hypothetical?

Have any researchers tested if babies are conditioned to imitate? That is, one group of infants receive a positive reward after imitation (such as a smile and verbal response from the adult) and the other group receives a neutral reaction with no positive or negative facial expression.
