It's an interesting topic, I have never thought about that at least going in depth. This experiment does show the principle of exchanging personal expressions is important to the living beings.
BTW this study comprises of the cooperation from both fields of computer/robotic engineering and psychology, amazing!!
To me baby's smiling means asking for some kind of demand and needing for response from us.
"Social robot" recalls the previous blog topic of A.I. I guess that's what we are heading to now - A.I. might be first widely used in the health care.
Before having read the article, I was thinking baby's crying is just other way of telling us things.
But I think that baby deliberately cries in front of their parents in which finds sense of caring themselves.
Whenever babies cry, it means food time or wanting get their parents' attention for a need.
I think it's more a reflex response though.
It's just like we will get food once getting hungry.
When people see baby crying that signals us check out what's happening to the baby. I agree what the article tends to show.
In my opinion, babies may do the trial-and-see attempt to their parents and look for the good outcomes.
I am more keen on believing both the reflex response and cognitive approach. The reason could be depending on what kind of circumstances the baby's facing.
For example the baby might just cry out aloud when it's time to have the diaper changed, not feeling well from the irritated skin.
Couldn't this attribute to both approaches?
I think that's something to do with nonverbal means of communication. May we apply it to our pets, let's say a puppy wants some water/ food it certainly swings its tail or barks a few times. Once it has the desired outcome just keeps on trying for more similar results.
We have taken many things for granted including as natural as baby crying and smiling.
Babies smile for their parents because want to get positive responses like complimenting/ extra caring.
the body of that robotic baby looks a bit creepy, is full of wires
the look is likely unwelcome though : )
but the main thing of this study somehow does show that mutual relationship between the baby and those interacting with him
it just reminds me what if we see a person at the first sight, shouldn't we'd better don't judge a book by its cover, always be nice.
The experiment reaffirms the reinforcement theory. Humans or even our pets will do things that leading them to have advantageous outcomes. While they are trying, looking for opportunities is also taken place at the same time.
We are the opportunist for most of the time.
It's the same analogy to employees who are being nice to their coworkers and boss, the more often being nice to them, there would be more chances of being treated well.
It's about exchanging smile with parent's caring.
I believe once humans need to socialize with others in a group, showing smile and being nice to others around you definitely secures your status.
Humans actually haven't known much about not only our world but themselves too.
It seems that smiling at people is universally welcome. It is a gesture of being friendly and nice to people.
But baby might start learning the gesture since trying with the parents.
It's a non-verbal means of communication. I think it might close to extrasensory perception/ telepathy.
Most babies by large could read/ sense the facial expressions of their parents or whoever taking care of them. They would react to the gestures of adults either by crying aloud or smiling back.
I guess it must be our first learning stage, so baby crying implies that some kind of need has to be regarded by the parents. That recalls our forefather who might use a few basic sounds expressing simple scenarios at that time.
I believe crying stands for getting a sense of caring from other. Baby cries for reasons like asking for food, clean up, checking discomfort, and getting the parents attention.
On the other hand they smile for getting compliment from the parents or some kind of reward. I want to say it is more an exchange of personal expression.
What I remember from some of resources mentioned before that nonverbal communication is actually more complex than verbal/ language communication.
Once babies know nothing about verbal communication so the only adaptive way is to express what they feel though smiling, crying, groaning, screaming.
I agree with most of your viewpoints.
Since humans are born to be socializing with other humans, at the beginning of the time our ancestors might just make some random sounds,and later categorize them and form a system.
The categorizing process of course takes some periods; in the meanwhile people might also use the sounds along with gestures and tones in order to make them with some meaningful sense.
Let's say I doubt anyone would feel good while seeing a baby cries out or sobs aloud. So it directs us to better check out what's going on.
First thing that comes to mind is to understand more in-depth about how we could possibly communicate without relying on verbal languages. Because it could be adopted by those who are deaf-mute or even anyone who speaks different languages from ours, starting off from general & simple greetings, demands or commands.
