Attitude and perception are differ in their fundamental nature, with attitude referring to a learned predisposition to respond towards an object, and perception referring to the process of interpreting sensory information. Measuring them requires different approaches based on the type of information we aim to gather.

Attitudes and perceptions both can be measured in different ways. To measure attitude, researchers use methods such as self-report questionnaires, semantic differential scales, and Likert scales, that typically involve asking a respondent to rate their agreement or disagreement with a series of statements. For example, a researcher might ask a respondent to rate how much they agree with statements such as "I enjoy shopping for new clothes" or "I think it's important to recycle". Perception can be measured using methods such as psychophysical scaling techniques and direct observation. Psychophysical scaling techniques are used to measure an individual's sensitivity to various stimuli, such as sound, light, or taste. Direct observation involves analyzing a respondent's behavior or verbal responses when exposed to a particular stimulus. For example, a researcher might observe how a respondent reacts to a particular type of food or how they respond to different types of visual stimuli.

Dear Ayush,

I agree with Dr. Ajit Singh here.

However, perceptions can also be measured using Likert scale. e.g. perception of youth on using Chat GBT; Perception of men on social norms in society. You may also use Vignettes to measure people's perceptions. Vignettes can be a hypothetical short story from the respondent's surroundings and below this you may ask questions from the story and these questions will reflect their perception regarding your subject. Hence, using various methods in a questionnaire you will be able to seek what you want.

All the best for your research.
