Original practice question bank · Questions 1–100
Introduction
PSYC 310 is a course code used by different institutions for psychology courses with
potentially different curricula. This practice question bank is designed to help students
prepare for a comprehensive psychology assessment covering material commonly
taught across introductory and intermediate psychology courses. It is organized as a
seven-quiz revision bundle, with challenging multiple-choice questions, applied
scenarios, and detailed explanations to strengthen understanding and exam readiness.
The material emphasizes applying psychological theories to real-world situations,
interpreting research findings, evaluating evidence, understanding human behavior,
and distinguishing between related psychological concepts. Each question has four
answer options, one best answer, and a rationale explaining why the correct choice is
appropriate and why the alternatives are less suitable.
Because the institution and official course syllabus have not been specified, the topics
below are a provisional study framework rather than a verified list of your course's
exact quiz objectives. Use this bank alongside your lecture notes, assigned readings,
and instructor-provided learning outcomes. The goal is to build conceptual
understanding, improve analytical reasoning, identify knowledge gaps, and practice
selecting the strongest answer in complex situations.

QUESTIONS 1–100
Quiz 1: Research methods and scientific
reasoning
Q1. A researcher randomly assigns participants to receive either a mindfulness
intervention or a control activity. Participants in the mindfulness group report less
anxiety afterward. Which conclusion is most justified if random assignment was
properly implemented and the groups were treated similarly?
A) Mindfulness permanently prevents anxiety disorders.
B) The intervention likely contributed to the observed difference in anxiety under the
study conditions.
C) Anxiety reduction must have resulted from participants' expectations alone.
D) The findings prove mindfulness is more effective than every other treatment.
Rationale: B is correct because random assignment and comparable treatment
conditions support a causal interpretation of the difference between groups. A is
incorrect because a short-term study cannot establish permanent prevention. C is
incorrect because expectancy effects are only one possible explanation and would
require further control or measurement. D is incorrect because superiority over all
other treatments requires direct comparative studies.
Q2. A researcher finds that hours of sleep and examination scores are positively
correlated. Which additional finding would most strongly support the possibility that
sleep contributes causally to performance?
A) Students who sleep longer also report greater happiness.
B) The correlation remains significant after rounding the scores.
C) Students with higher grades retrospectively estimate their sleep more accurately.
D) Randomly assigned sleep-extension participants outperform an appropriate control
group under controlled conditions.
Rationale: D is correct because a randomized intervention can reduce confounding
and strengthen causal inference. A identifies another association, not causation. B
, 4
concerns numerical presentation rather than causal validity. C introduces possible
measurement differences and reverse causation rather than resolving them.
Q3. A psychological scale produces nearly identical scores when administered twice
to stable participants, but it measures general distress rather than the specific construct
of social anxiety. The scale demonstrates:
A) High construct validity and low reliability.
B) Low reliability and high predictive validity.
C) High test–retest reliability but inadequate construct validity for social anxiety.
D) High content validity because the scores are consistent.
Rationale: C is correct because consistency over time indicates test–retest reliability,
whereas failure to measure the intended construct indicates poor construct validity. A
reverses the reliability finding. B contradicts the evidence of consistency and provides
no evidence of predictive validity. D confuses consistency with coverage of the
intended content.
Q4. A researcher recruits volunteers from an online forum devoted to panic attacks
and uses their responses to estimate panic-attack prevalence in the general population.
What is the principal limitation?
A) Random assignment has failed.
B) The study cannot calculate any descriptive statistics.
C) The sample necessarily contains only people with a clinical diagnosis.
D) Self-selection and sampling bias may make the sample unrepresentative of the
population.
Rationale: D is correct because people who join and respond to a panic-focused forum
may differ systematically from the general population. A concerns experimental
allocation, which is not the main issue in a prevalence survey. B is false because
descriptive statistics can still be calculated. C is unsupported because forum
membership does not establish a formal diagnosis.
Q5. An experiment tests whether background music affects concentration.
Participants who hear music also receive brighter lighting than participants in silence.
What is the principal design problem?
A) The dependent variable cannot be measured.
B) Lighting is confounded with music, so the independent effect of music cannot be
isolated.
C) The experiment contains no independent variable.
