Language Development & Child Development

These twins do not realize that they have already been born, yet exhibit familiar expressions of affection for each other.  From an interesting blog,  a peaceful warrior:

Language- Does language develope from a strictly cognitive process or do we need more emotional, physical and relational influences?

Experiment:  Invent and define five new words.  These invented words must be verbs and must be simple actions that one can do in everyday life.  Example: snorfie might mean to hold your nose closed for three seconds.  Next, recruit six people.  Randomly divide them into two groups of three, and place each group in a different room.  The three people assigned to Group A must spend
five minutes memorizing the new words and their definitions.  The three people in Group B must learn the five new words by acting them out repeatedly for five minutes, for example, pinching their noses closed for three seconds and saying "snorfie".

Data collection:  At the end of the five minutes, hand each person a blank sheet of paper and a writing utensil and ask them to write the words and definitions.  Count the number of correct answers from Group A and average their scores.  Do the same for Group B's scores.  Does one group's results suggest that their learning method was more successful than the others?

Language Acquisition - Does every child progress at the same rate?
What factors might prevent a child from acquiring language at a normal progression?

 Too Late for Words:  The Case of Genie
https://www.youtube.com/watch?v=hmdycJQi4QA

Be ready to answer the following questions:
Why was Genie unable to speak coherently or understand language when she was found?
Describe Genie's ability to learn to use language properly.  How much progress in language did Genie make? 

What conclusions can you draw from this case and your study of the chapter regarding a window of opportunity to learn language?  Are the results conclusive?

Evaluate the importance of language and human interaction.  From the word experiment and the case of Genie, can we learn a language strictly through cognition?  What other factors might be necessary?
Is there more to language that just a transaction or words?
