Week 3 Assessment — Sensation, Perception & Attention

Mastery Authority

Stored assessment evidence controls Week 3 mastery

Daily reviews support learning. Week 3 mastery comes only from a weekly assessment score of 80% or higher.

Form A · First Attempt

Week 3 Knowledge Check

1. Transduction is: assigning meaning to an ambiguous stimulus converting physical stimulus energy into neural signaling remembering a stimulus after it disappears

2. Proprioception provides information about: sound frequency color wavelength position and movement of body parts

3. Perceptual constancy helps people: perceive object properties as relatively stable despite changing sensory input detect every stimulus equally eliminate all illusions

4. Inattentional blindness is: permanent loss of vision failure to notice an unexpected visible stimulus while attention is engaged elsewhere forgetting visual information after a week

5. A person identifies a flavor more accurately when smell is available than when smell is reduced. Best conclusion? the tongue contributes nothing to flavor smell always dominates every sensory system smell contributed to flavor identification under these conditions

6. The same ambiguous symbol is read as B in A_C and 13 in 12_14. This best illustrates: context and perceptual set influencing interpretation transduction failure sensory adaptation

7. Why are absolute thresholds often estimated across many trials? because sensation cannot be measured detection is probabilistic and can vary with conditions because every trial must produce the same answer

8. To test a multitasking claim fairly, researchers should: compare different people doing unrelated tasks once ask whether participants feel talented at multitasking compare defined single-task and dual-task conditions using performance measures

9. Visual-search reaction time increases from 410 ms with 4 distractors to 690 ms with 24 distractors. What is directly supported? attention stopped working search time increased as display size increased in this task every real-world search behaves identically

10. Which statement best respects Week 3's limits? perception is completely arbitrary people from one culture all perceive the same way perception is shaped by context and experience while remaining constrained by physical information and biological processing

Answer all 10 questions, then score the assessment.

Targeted Correction

Review before Form B

Write one correction rule you will carry into the retake.

Form B · Parallel Retake

New questions, same standards

1. Sensory adaptation is best described as: reduced responsiveness to constant stimulation over time permanent loss of a sense top-down interpretation of an ambiguous symbol

2. Which statement about flavor is most accurate? flavor occurs entirely on the tongue taste, smell, texture, temperature, vision, and expectation can contribute smell is the only relevant sense

3. Top-down processing is influenced especially by: only receptor firing only physical wavelength expectations, prior knowledge, goals, and context

4. Change blindness shows that: substantial scene changes can be missed when attention is interrupted or elsewhere visual input never reaches the eye perception has no relation to physical input

5. Two equal objects look different in size because surrounding context differs. Best explanation? one object physically changed size contextual organization influenced size judgment the observer lost visual sensation

6. A trained radiologist notices a meaningful image pattern a novice misses. This can illustrate: experts inhabit a different physical reality experts never make perceptual errors experience and expertise can alter pattern recognition and attention

7. In a detection experiment, the independent variable is most likely: stimulus intensity manipulated across trials participant diagnosis the conclusion paragraph

8. Which pair is useful for measuring divided-attention costs? favorite color and height reaction time and accuracy across single- and dual-task conditions horoscope sign and mood

9. The same ambiguous symbol is called A by 78% after one cue and B by 69% after another. What is strongest? the cue physically changed the symbol context has no effect context influenced the distribution of interpretations under these conditions

10. Which statement is scientifically responsible? group differences in perception are tendencies and do not define every individual member one group average proves how every member perceives perceptual variation means no external facts exist

Form B is a parallel assessment, not a duplicate.
