QCM : Introduction to Biological Psychology — 10 questions

Question 1

1. What does Biological Psychology primarily study?

The development of psychological theories over time.

The methods used in clinical psychology to treat mental disorders.

The influence of biological processes on thoughts, emotions, and behaviors.

The psychological effects of social and environmental factors.

Explication

Biological Psychology, also known as biopsychology, is primarily concerned with understanding how biological processes, especially within the nervous system, influence psychological functions such as thoughts, emotions, and behaviors. It explores the biological underpinnings of mental processes, making option 2 the correct answer.

Answer

The influence of biological processes on thoughts, emotions, and behaviors.

Question 2

2. What is the primary focus of Biological Psychology?

To study how biological processes influence thoughts, emotions, and behaviors

To analyze only the chemical composition of the brain

To explore cultural impacts on psychological development

To develop new psychological therapies without biological basis

Explication

Biological Psychology (or Biopsychology) mainly examines how biological processes, especially within the nervous system, influence our mental experiences and behaviors, unlike approaches that focus solely on environment or culture.

Answer

To study how biological processes influence thoughts, emotions, and behaviors

Question 3

3. Who was the scientist that established the neuron doctrine, demonstrating that neurons are discrete cells in the nervous system?

Camillo Golgi

Santiago Ramón y Cajal

Hugo Spemann

Charles Sherrington

Explication

Santiago Ramón y Cajal is credited with establishing the neuron doctrine, which demonstrated that neurons are individual, discrete cells. This discovery was fundamental in understanding the structure of the nervous system. Camillo Golgi developed a staining method but did not establish the neuron doctrine. Charles Sherrington studied synaptic transmission, and Hugo Spemann was known for work on neural regeneration, but neither established the neuron doctrine.

Answer

Santiago Ramón y Cajal

Question 4

4. Which of the following is NOT a traditional neuroimaging technique used in biological psychology?

MRI

fMRI

PET

CTE scans

Explication

CTE scans are not a neuroimaging technique; instead, they refer to a neurodegenerative disease linked to injuries, whereas MRI, fMRI, and PET are standard neuroimaging methods.

Answer

To receive incoming signals from other neurons

Answer

Santiago Ramón y Cajal

Answer

They facilitate communication across synapses by acting as chemical messengers

Answer

Frontal lobe

Answer

Genetics and hormones of the endocrine system

Answer

To measure electrical activity of the brain directly

Question 5

5. What is the primary function of dendrites in a neuron?

To insulate the axon and increase signal speed

To release neurotransmitters into the synaptic cleft

To receive incoming signals from other neurons

To transmit electrical impulses away from the neuron’s cell body

Explication

Dendrites are branched extensions of a neuron that primarily serve to receive incoming signals from other neurons. They collect electrical signals and transmit them to the cell body for processing. The other options describe functions of different neuron parts: the axon transmits impulses, the myelin sheath insulates the axon, and the synapse is involved in neurotransmitter release.

Question 6

6. Who is most associated with the development of the neuron doctrine, emphasizing neurons as independent units?

Santiago Ramón y Cajal

Jean Piaget

Francis Crick

Henry Molaison

Explication

Santiago Ramón y Cajal was pivotal in establishing that neurons are discrete cells, a fundamental concept in neuroscience, known as the neuron doctrine.

Question 7

7. What role do neurotransmitters play in neuronal communication?

They facilitate communication across synapses by acting as chemical messengers

They insulate neurons to prevent electrical signals from escaping

They conduct electrical signals along the neuron’s axon directly

They diminish the activity of all neurons uniformly

Explication

Neurotransmitters are chemicals released at synapses to help neurons communicate; they do not insulate or directly conduct electrical signals along the axon.

Question 8

8. Which brain lobe is primarily responsible for reasoning, decision-making, and planning?

Frontal lobe

Occipital lobe

Temporal lobe

Parietal lobe

Explication

The frontal lobe is key for higher cognitive functions such as reasoning and decision-making, differentiating it from other lobes associated with vision, hearing, or sensory processing.

Question 9

9. Which biological factors are studied in relation to their influence on behavior, development, and mental processes?

Genetics and hormones of the endocrine system

Only environmental influences

Cultural traditions and beliefs

Technological innovations in psychology

Explication

Genetics and hormones in the endocrine system are fundamental biological factors that influence behavior and mental processes, central to biological psychology.

Question 10

10. What is a primary aim of using electrophysiological techniques like EEG in biological psychology?

To measure electrical activity of the brain directly

To visualize detailed brain structures

To measure blood flow in the brain

To assess genetic influences on behavior

Explication

EEG records electrical activity produced by neurons, providing direct insights into brain function and real-time neural dynamics.
