____________ conditioning is the most effective method for establishing a conditioned
response.
A. Backward
B. Trace
C. Delay
D. Simultaneous - ✔✔C. Delay
Delay conditioning is a type of forward conditioning in which presentation of the
conditioned stimulus precedes and overlaps presentation of the unconditioned
stimulus. Of the methods for presenting the conditioned and unconditioned stimuli,
delay conditioning produces the fastest acquisition of the conditioned response.

,B. APOE3
C. APOE2
D. APOE1 - ✔✔A. APOE4
There are three main variants of the APOE (apolipoprotein E) gene: APOE2, APOE3,
and APOE4. APOE2 is the rarest variant and its presence reduces the risk for
Alzheimer's disease, while APOE3 is the most common variant and its presence doesn't
seem to affect the risk for Alzheimer's disease. In contrast, APOE4 has been linked to an
increased risk for Alzheimer's disease and several other neurocognitive disorders
including neurocognitive disorder due to Lewy body disease. APOE1 is very rare and
has not been linked to Alzheimer's disease.

,L. L. Carstensen, J. M. Gottman, and R. W. Levenson found that dissatisfied older
married couples were less likely than dissatisfied middle-aged couples and satisfied
older and middle-aged couples to engage in "negative start up" - i.e., they were less
likely to respond to their partners' expressions of neutral affect with expressions of
anger, disgust, or other negative emotions during discussions of their marital problems.
Research on smoking cessation interventions suggests that:
A. neither counseling nor medication are effective when used alone and, therefore,
should always be combined.
B. counseling and medication are each effective when used alone but the combination of
counseling and medication is most effective.
C. counseling alone is as effective as counseling plus medication.
D. medication alone is as effective as medication plus counseling. - ✔✔B. counseling
and medication are each effective when used alone but the combination of counseling
and medication is most effective.
Piaget proposed that, during substage 3 (secondary circular reactions) of the

, B. repeats behaviors that elicit a response from a person or object.
C. deliberately changes a behavior to determine the consequences of doing so.
D. coordinates two or more responses to solve a problem. - ✔✔B. repeats behaviors that
elicit a response from a person or object.
As described by Piaget, the substages of the sensorimotor stage involve different types
of circular reactions, which are actions that are performed to repeat an event that first
occurred by chance. Substage 3 occurs between four and eight months of age and is
characterized by secondary circular reactions, which are goal-directed actions that elicit
a response from a person or object. For example, an infant might repeatedly kick the
mobile hanging over his crib to make it move.
Which of the following decreases the risk for sudden infant death syndrome (SIDS)?
A. breastfeeding the baby and having the baby sleep on his/her back
B. having the baby sleep on his/her stomach and keeping the crib as bare as possible
C. breast feeding the baby and having the baby co-sleep with his/her parents
D. using crib bumpers in the baby's crib and having the baby sleep on his/her back -
