Explanation
The correlation method is advantageous because it allows for making predictions. By examining the relationship between two variables, the correlation method can provide insights into how changes in one variable may affect the other. This information can then be used to make predictions about future outcomes or behavior. Therefore, the statement that the major advantage of the correlation method is its ability to make predictions is true.

Explanation
The correct answer is "behavioural psychologists" because researchers who adopt the biological perspective in psychology focus on studying and understanding human behavior through the lens of biological factors, such as genetics, brain structure, and chemical imbalances. They investigate how these biological factors influence and interact with behavior, emotions, and mental processes. Therefore, the term "behavioural psychologists" accurately describes researchers who adopt the biological perspective in psychology.

Explanation
The hypothalamus is responsible for regulating almost all bodily functions except blood pressure, heart rate, and breathing. It plays a crucial role in maintaining homeostasis by controlling body temperature, hunger, thirst, sleep, and hormone production. It also helps regulate emotions, sexual behavior, and the release of hormones from the pituitary gland. The thalamus is involved in relaying sensory information to the cerebral cortex, while the hyperthalamus and amygdala do not have the same level of control over bodily functions as the hypothalamus.

Explanation
Glial cells are specialized cells that provide support and protection to neurons in the nervous system. They hold neurons in place, provide insulation to axons, and aid in the transmission of signals between neurons. Glial cells also play a role in regulating the chemical environment around neurons and assisting in the repair of damaged neurons. Therefore, glial cells are the specialized cells that hold neurons in place.

Explanation
The autokinetic illusion occurs when a stationary light in a dark environment appears to move. This phenomenon is caused by the involuntary small movements of the eyes, known as microsaccades. These tiny eye movements cause the light to appear as if it is moving, even though it is actually stationary. Therefore, the correct answer is "Movement of the eyes."

Explanation
The cortex is not considered one of the three major parts of the brain and its functions. The three major parts of the brain are the cerebrum, cerebellum, and brainstem. The cerebrum is responsible for higher cognitive functions, such as thinking and memory. The cerebellum controls coordination and balance. The brainstem regulates basic functions like breathing and heart rate. The cortex, on the other hand, refers to the outer layer of the cerebrum and is involved in complex processes such as perception, language, and consciousness.
