Q:
|
A study is performed on various reinforcement schedules and it discovers that a fixed interval schedule conditions a response faster than all other schedules. From this data, it can be extrapolated that: |
|
A
|
rewards given after fixed numbers of responses do not result in any conditioning. |
B
|
rewards given after a specific amount of time has elapsed is more rapid at conditioning a response than rewards given at random times. |
C
|
if the animal is unable to predict the number of responses required for a reward, the conditioning is expedited. |
D
|
extinction will take place at a similar pace for all reinforcement schedules. |

hereditary influences can contribute largely to intelligence. |
B
|
environmental influences can contribute largely to intelligence. |
C
|
hereditary influences are unrelated to intelligence. |
D

Q:
|
Several studies were performed in the 1980s evaluating the intelligence of various individuals based on adoption status. Individuals who were adopted were found to have intelligence quotient scores strongly aligned with their biologic parents and weakly aligned with their adoptive parents. This suggests: |
|
A
|
that genetics supersede environment for intelligence traits. |
B
|
the development of intelligence is initially heavily reliant on biological factors however environmental factors grow to become more important over time. |
C
|
the equal interplay of environmental and genetic factors in intelligence. |
D
|
genetics are minimally responsible for the development of intelligence. |
