Sensation, Perception and Attention
Candidates should connect sensory input, thresholds, perceptual organization, depth cues, attention, and interpretation of stimuli.
How to study for CLEP Introductory Psychology
Connect every question to a perspective, research method, concept definition, evidence pattern, and application clue before choosing the answer.
Core concepts
Concept 1
Sensation, Perception and Attention questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Sensation
Sensation detects physical stimulation through sensory receptors.
Perception
Perception organizes and interprets sensory information.
Absolute Threshold
Absolute threshold is the minimum stimulation needed to detect a stimulus about half the time.
Difference Threshold
Difference threshold is the smallest detectable difference between two stimuli.
Signal Detection
Signal detection theory explains detection as a mix of sensitivity and decision criteria.
Gestalt Principle
Gestalt principles describe how people organize parts into meaningful wholes.
Depth Cue
Depth cues help judge distance and three-dimensional space.
Selective Attention
Selective attention focuses awareness on some stimuli while filtering others.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
