Attitude vs Perception

Can you differentiate between attitude and perception? The two terms seem to mean quite the same thing, but there's a great difference in thier implication.

I will enunciate on the topic as per the principle of consumer behaviour. Perception refers to an opinion formed about a product or brand on reception of a stimulus. Every stimulus (selectively percieved stimulus) leads to formation of perception. Now once perception is formed about a product, consumers tend to learn more about the product or brand. Once learning comes up to the desired level, consumers form attitude.

Now, the difference between these two psychological domains lies in the fact that every single stimuli forms a perception, while attitude is a consequence of learning about a product/brand, which in turn is the outcome of perception(s). Consumers may have different needs for cognition. As such, consumer learning comes from multiple stimuli leading to multiple perceptionm.

In a nutshell, consumers first percieve, learn from perception/s (on account of single or multiple stimuli depending on their need for cognition) and then forn attitudes, which dictate their purchase decisions.
