Semantic Differential

INTRODUCTION
English translation pending.
CORE DEFINITION
The semantic differential measures the affective meaning of a concept by having respondents place it between bipolar adjective pairs such as good-bad, strong-weak, and fast-slow. Each rating converts an impression into a number, and the set of ratings locates the concept as a point in a low-dimensional space, typically spanning evaluation, potency, and activity. Because every concept is measured on the same scales, profiles can be compared, clustered, and tracked over time, which is why the method is used to contrast brands, institutions, and product perceptions.
SCAFFOLDING EFFECT
Reduce cognitive load
- Locate the feeling: plot a concept's ratings instead of trusting the adjectives in a discussion. - Compare profiles directly: compute the distance between two concepts on the same shared scales. - Watch for profile drift: re-measure after an intervention to see whether perception actually moved.
Anchor fast decisions
Impressions feel unitary but are not: the method factorizes a feeling into a few continuous dimensions, each realized as a bipolar scale. Marking a position on a scale converts private appraisal into a public coordinate, and once two concepts share a coordinate system, their similarity becomes arithmetic. This is the causal chain: dimensional decomposition makes the intangible measurable, and shared measurement makes profiles comparable.
