HOSA Behavioral Health Knowledge Exam
Study Guide 2025/2026 | Verified &
Comprehensive | 100% Accurate
What is the central idea behind the humanistic perspective in psychology?

It views people as inherently good, with a natural drive to learn and enhance their potential.



How does the behavioral approach to psychology differ from other schools of thought?

It focuses on the study and precise measurement of observable behaviors rather than internal
mental states.



What is the primary focus of biological psychology?

It examines the connection between biological processes and their influence on behavior.



Which concept explains the relationship between an organism’s physical traits and behaviors that
contribute to its survival and reproduction?

This is explained by evolutionary psychology, which suggests that both physical structures and
behaviors are shaped by evolutionary pressures.



How does cognitive psychology explain human behavior?

Cognitive psychology emphasizes information processing, including the mechanisms of thinking,
reasoning, and problem-solving.



What does social psychology investigate?

It explores how the social environment and interactions with others influence individual behavior.



How does developmental psychology contribute to our understanding of human behavior?

It studies the typical behavioral changes and growth that occur throughout the lifespan of an
individual.


1

,What is the role of clinical psychology?

Clinical psychology focuses on diagnosing, defining, and treating abnormal behavior and mental
disorders.



What was the central claim of phrenology in the early study of psychology?

Phrenology proposed that the shape and bumps on a person’s skull could indicate their mental
abilities and personality traits.



How is biological psychology distinguished from other branches?

Biological psychology connects the study of biology and behavior, seeking to understand how
biological processes impact mental functions and actions.



What is the fundamental function of a neuron?

A neuron is a nerve cell that transmits electrical impulses within the nervous system.



What role do sensory neurons play in the nervous system?

Sensory neurons carry incoming information from sensory receptors to the brain or spinal cord,
helping us process stimuli from the environment.



How do motor neurons function within the nervous system?

Motor neurons transmit outgoing signals from the brain and spinal cord to muscles and glands,
facilitating movement and physiological responses.



What is the role of interneurons in the central nervous system?

Interneurons communicate between other neurons, particularly in the brain and spinal cord, and
help regulate sensory and motor information.



What do dendrites do in a neuron?

Dendrites are branched extensions from the neuron’s cell body that receive signals from other
neurons and conduct impulses toward the cell body.

2

, How do axons contribute to neural communication?

The axon is an extension of a neuron that carries electrical impulses away from the cell body
toward other neurons, muscles, or glands.



What is the purpose of the myelin sheath in neural transmission?

The myelin sheath is a fatty layer surrounding neuron fibers that increases the speed and
efficiency of electrical impulses traveling along the axon.



What does the action potential refer to in neural activity?

An action potential is a brief electrical charge that travels down an axon, enabling communication
between neurons.



What is the threshold in neural processing?

The threshold is the minimum level of stimulation required to trigger an action potential,
determined by the balance of excitatory and inhibitory signals.



What is the synapse, and what role does it play in neural communication?

The synapse is the gap between the axon of one neuron and the dendrite of another, where
neurotransmitters are released to transmit signals between neurons.



How do neurotransmitters function within the brain?

Neurotransmitters are chemical messengers that cross the synaptic gap and bind to receptor sites
on a neighboring neuron, influencing its activity.



What are endorphins, and what functions do they serve?

Endorphins are natural opiate-like neurotransmitters that help manage pain and promote feelings
of pleasure.



What role does acetylcholine play in the body’s functions?
