Question

3) Using a mobile –kick paradigm, Rovee-Collier and colleagues had infants lie in a crib. A string attached the infant’s ankle to the mobile so they could cause the mobile to move by kicking. Then the string was unattached to the mobile and infant kicking was measured with no delay. What did the results display?

a) Infants quickly grew bored with the mobile, displaying disengagement

b) Infants kicked more after being attached to the mobile, displaying memory

c) Infants kicked the same amount, displaying no understanding of control

d)None of the above

4) Speak strangely Yoda does. What aspect of language does this illustrate?

a)Lexical Inertia

b)Productivity

c)Regularity

d)Syntactic Development

Answer 1

(3) Mobile-kick paradigm or mobile conjugate reinforcement paradigm intended to check infant's retention of memory with tasks. This is related to associate learning in infants. Mobile-kick paradigm experiment is opined to be suitable for measuring memory retention and associated learning pattern in infants from 2 to 3 months of age.

Here in this case, there is very less chance of memory fading as string responsible for movement of mobile overhead is detached and the kicking movement of infant measured with no delay (which means no interval time given). The kids just learned about associated movements with regard to mobile and ankle string, and infants still retains that learning. We can see there is no room for infantile amnesia or fading of memory associated with learning in this case.

We can say the resultant activity by infants kick more due to recent learning of control of mobile movements associated with kicks when compared to baseline of no attachment, hence option B is the right option.

(4) Yoda is a character in Star Wars. It is observed character Yoda speaks backwards (even though not full backward sentences, it is mixed), but still the sentences can be understood. Yoda splits verbs and manipulates order of sentences which result in odd syntax for language. Syntactic Development phase in language refers to learning to combine words to form sentences and phrase sentences.

In this case, by observing the Yoda's language, we can say (d) syntactic development is illustrated.
