MKTG6007 Chap.2 Perception
Perception
The consumer information chain moves from exposure to attention, perception and comprehension. This chapter shows why those are distinct failures, how the five senses register stimuli, how absolute and differential thresholds determine notice, how Weber's Law makes detectable change proportional to the baseline, and how prior knowledge affects meaning.
The stages matter because the same weak response can arise for different reasons. A consumer cannot attend to a stimulus that never enters sensory range, may be exposed without allocating attention, and may notice a claim while assigning an unintended meaning. Assessment analysis should therefore locate the breakdown before offering a fix.
Threshold reasoning helps evaluate whether a physical change is detectable, while perceptual organisation and knowledge explain why a detected pattern is interpreted in a particular way. A responsible recommendation pairs the mechanism with an observable test, such as recognition, comprehension or comparison performance, rather than assuming that a more prominent execution automatically produces better understanding.

Key terms
- Exposure
- Sensory contact between a consumer and a stimulus.
- Attention
- The allocation of limited mental activity to part of the environment.
- Perception
- The registration and organisation of stimuli through the senses.
- Absolute threshold
- The minimum intensity at which a stimulus becomes detectable.
- Differential threshold
- The change between stimuli that is just large enough to be noticed.
- Comprehension
- The meaning a consumer gives to perceived information using prior knowledge.
Perception FAQ
What is the difference between attention and comprehension?
Attention concerns whether mental activity is allocated to the stimulus. Comprehension comes later and concerns the meaning given to what was perceived. A consumer can notice a claim clearly and still misunderstand it, so the remedy depends on the failed stage.
How should I explain a just noticeable difference?
Describe it as the change between two detectable stimuli that is just large enough to be noticed. Under Weber's Law, the required absolute change grows with the baseline because the detectable change is modelled as a constant proportion of the original stimulus.
How do MAO conditions affect comprehension?
Low motivation can reduce willingness to interpret, low ability can limit knowledge or skill, and low opportunity can restrict time or attention. Identify the relevant condition from evidence rather than assuming every unclear response has the same cause.
Does greater exposure guarantee attention?
No. Exposure only places the stimulus within sensory range. Consumers may allocate attention elsewhere because the message lacks relevance, competes with stronger cues or appears when time is scarce. Demonstrate attention with an appropriate observation rather than inferring it from media placement or display size alone.
When should I use threshold reasoning in an analysis?
Use thresholds when the question concerns whether a sensory difference can be detected, not when the real issue is the meaning attached to a detected change. State the baseline, the relevant change and the predicted detectability, then separate that sensory claim from any later judgement about quality or fairness.
Assessment move
Draw a four-column perception log labelled stimulus, exposure, attention and comprehension. For each package, interface or advertisement, place observations in the correct column and refuse to fill a later stage without evidence. This simple discipline reveals why reach data do not prove attention and why attention measures do not prove correct interpretation. Next, practise paired failures.
Use one example in which a claim is physically difficult to detect and another in which it is prominent but ambiguous. For each, write a distinct remedy and a measure that could show whether the remedy worked. Build threshold fluency separately. Record a baseline stimulus, apply the relevant proportional change, and explain in words why a larger baseline can require a larger absolute change for detectability.
Check units and direction before interpreting the number. Then remove the calculation and decide whether the scenario actually calls for a just noticeable difference or for comprehension analysis. For assessment work, use a stage–mechanism–test paragraph: locate the failed perceptual stage, cite the scenario cue, explain how MAO or prior knowledge affects processing, and propose a measure at that same stage.
Add a boundary sentence acknowledging that detection does not establish preference and comprehension does not guarantee behaviour. Finish revision by contrasting absolute threshold with differential threshold, attention with comprehension, and bottom-up sensory input with top-down interpretation. Explain each contrast through one fresh marketplace example rather than repeating definitions.
This produces flexible diagnosis and stops every weak message from receiving the same recommendation to make it bigger or brighter.
