1. Select all of the following neurotransmitters that are primarily categorized as inhibitory in
the central nervous system:
A. C and D only
B. Dopamine
C. GABA (Gamma-aminobutyric acid)
D. Glycine
E. Norepinephrine
F. Glutamate
Correct Answer: A
GABA is the primary inhibitory neurotransmitter in the brain, while Glycine serves a
similar role in the spinal cord. These chemicals function by hyperpolarizing the
postsynaptic neuron, making it less likely to fire an action potential. In contrast, Glutamate
is the brain’s primary excitatory neurotransmitter.
,2. In the context of Piaget’s stages of cognitive development, a child who can perform mental
operations on concrete objects but struggles with abstract or hypothetical reasoning is in
which stage?
A. Sensorimotor
B. Preoperational
C. Formal Operational
D. Concrete Operational
Correct Answer: D
The Concrete Operational stage typically occurs between the ages of 7 and 11. During this
time, children develop logical thinking about physical events and understand the concept of
conservation. However, they generally cannot yet manipulate concepts that are purely
abstract or hypothetical in nature.
3. An experimenter wants to determine if a new study technique improves test scores. In this
study, the ‘new study technique’ represents which variable?
A. Dependent Variable
B. Confounding Variable
C. Independent Variable
D. Control Variable
Correct Answer: C
, The independent variable is the factor that is manipulated by the researcher to observe its
effect. Test scores would be the dependent variable, as they are expected to change based
on the study technique used. This experimental design allows researchers to establish
cause-and-effect relationships between variables.
4. Which part of the neuron is responsible for receiving signals from other neurons?
A. Dendrites
B. Axon
C. Myelin Sheath
D. Terminal Buttons
Correct Answer: A
Dendrites are branch-like structures that extend from the cell body and pick up chemical
messages from neighboring cells. These signals are then integrated at the axon hillock
before an action potential is triggered. The efficiency of this reception is crucial for neural
communication and overall cognitive function.
5. Identify the primary function of the hippocampus within the limbic system:
A. Consolidating short-term memory into long-term memory
B. Regulating hunger and thirst
C. Processing fear and aggression
D. Controlling motor coordination
