QCM : Foundations of Psychology and Sleep Science — 12 questions

Explication

The correct application is to time sleep so that you complete multiple full cycles, which include all stages of sleep, especially deep sleep and REM, to maximize restorative benefits. Waking during REM sleep (option 1) is generally not recommended as it can cause grogginess. Avoiding deep sleep stages (option 3) is counterproductive, as these are crucial for physical restoration. Sleeping as long as possible without regard to stages (option 4) ignores the importance of sleep architecture for quality sleep.

Explication

Operant conditioning's main function is to modify voluntary behaviors through reinforcement or punishment, shaping how individuals behave based on consequences.

Explication

Wilhelm Wundt established the first psychology laboratory in 1879, which is considered the beginning of psychology as a scientific discipline.

Explication

Sleep apnea is characterized by repeated interruptions in breathing during sleep, which is a defining feature of the disorder. The other options describe symptoms or features associated with other sleep issues but are not specific to sleep apnea.

Explication

A clinical psychologist's main function is to diagnose and treat mental health issues through therapy and assessment, which distinguishes their role from researchers, educators, or administrators.

Explication

B.F. Skinner is credited with proposing operant conditioning, a learning process where behavior is shaped by reinforcement and punishment, making him the correct answer. Pavlov is known for classical conditioning, Watson for behaviorism and the Baby Albert experiment, and Bandura for observational learning, but none proposed operant conditioning.

Explication

Ivan Pavlov is the scientist credited with discovering classical conditioning through his experiments with dogs, where he demonstrated how a neutral stimulus (bell) could be associated with an unconditioned stimulus (food) to elicit a conditioned response (salivation). The other options are notable psychologists but are associated with different learning theories or experiments.

Explication

A psychology perspective is a way of understanding human behavior and mental processes by viewing phenomena through different lenses or approaches, such as biological, cognitive, or sociocultural.

Explication

The scientific method in psychology was established with Wilhelm Wundt's founding of the first psychology laboratory in 1879, marking the beginning of psychology as a scientific discipline.

Explication

Classical conditioning is a learning process in which a neutral stimulus becomes associated with an unconditioned stimulus to produce a conditioned response, as demonstrated in Pavlov's experiments with dogs.

Explication

Sleep deprivation is known to impair cognitive functions, including memory and concentration, and can lead to mental fog and decreased alertness. The other options are incorrect because sleep deprivation does not improve memory or immune function; rather, it impairs them.

Explication

Correlational research examines the relationship between variables without manipulating them, meaning it cannot establish causality. Experimental research involves manipulating an independent variable to observe its effect on a dependent variable, allowing researchers to determine cause-and-effect relationships. This fundamental difference is crucial in research methodology.
