Psychology Degree Principles of Psychology 5 — Questions and Answers
Question 1: According to Erikson's psychosocial theory, the central conflict of adolescence is:
- Autonomy vs. shame and doubt
- Intimacy vs. isolation
- Industry vs. inferiority
- Identity vs. role confusion (Correct answer)
Correct answer: Identity vs. role confusion
Erikson described adolescence as the stage where individuals must forge a coherent sense of self or risk confusion about their roles in society.
Question 2: A researcher finds that as ice cream sales increase, drowning rates also increase. This most likely reflects:
- Ice cream causes drowning
- Drowning causes ice cream sales
- A third variable (hot weather) causes both (Correct answer)
- Random sampling error
Correct answer: A third variable (hot weather) causes both
This classic example illustrates spurious correlation — hot weather drives both ice cream consumption and swimming (drowning risk), making them correlated without causation.
Question 3: The gate-control theory of pain proposes that pain perception can be modulated by:
- Endorphin release only
- Neural gates in the spinal cord that can be opened or closed (Correct answer)
- The somatosensory cortex blocking signals
- Dopamine suppressing pain signals
Correct answer: Neural gates in the spinal cord that can be opened or closed
Melzack and Wall's gate-control theory suggests spinal cord mechanisms can amplify or inhibit pain signals before they reach the brain.
Question 4: The phi phenomenon, in which stationary lights flashing in sequence create the perception of movement, is an example of:
- Perceptual constancy
- Gestalt figure-ground principle
- Apparent motion and Gestalt principles (Correct answer)
- Bottom-up processing
Correct answer: Apparent motion and Gestalt principles
The phi phenomenon, demonstrated by Wertheimer, shows how the brain (Gestalt) constructs the perception of continuous motion from discrete stimuli.
Question 5: Which ethical principle, central to the APA's guidelines, requires psychologists to avoid actions that harm research participants or clients?
- Fidelity
- Justice
- Nonmaleficence (Correct answer)
- Autonomy
Correct answer: Nonmaleficence
Nonmaleficence — 'do no harm' — is a core APA ethical principle requiring psychologists to minimize risk and avoid causing harm.
Question 6: Cognitive dissonance theory, proposed by Leon Festinger, states that people are motivated to reduce discomfort caused by:
- Unmet biological needs
- Social rejection
- Holding contradictory beliefs or behaviors (Correct answer)
- Failure to achieve goals
Correct answer: Holding contradictory beliefs or behaviors
Festinger showed that inconsistency between attitudes and behaviors creates psychological tension that people resolve by changing one element.
Question 7: Which approach to psychology emphasizes the role of unconscious processes, early childhood experiences, and internal conflicts in shaping behavior?
- Humanistic psychology
- Behavioral psychology
- Cognitive psychology
- Psychodynamic psychology (Correct answer)
Correct answer: Psychodynamic psychology
Psychodynamic psychology (rooted in Freud) focuses on unconscious drives, early experiences, and defense mechanisms as determinants of behavior.
According to Erikson's psychosocial theory, the central conflict of adolescence is:
