I am confused on these 2 terms
The central route of persuasion is a method of changing someone else’s attitude by using data, facts, logic, reason, basically “the cold hard facts.” It is a companion term with peripheral route of persuasion, which occurs when one’s attitude is persuaded due to secondary reasons such as how cute the speaker might be.
Phonemes are a totally different topic, related to how we use language. Phonemes are the smallest individual units of speech that your mouth can make which DO NOT have meaning on their own. For example, make the “t” sound out loud. You can make that sound, but unless it’s part of a bigger word/noise, it doesn’t mean anything. This is a phoneme.
These are really from two areas, so it should be easy to draw a distinction.
The Central Route to Persuasion is from social psychology (social-cognitive) and refers to the persuasive power of the message “head on” - you judge the content and are persuaded.
Phonemes are what you are hooked on in phonics. They are consonent-vowel combinations that make up spoken language. There are a few dozen, most languages are organized around a group of them. Babies start to use phonemes as part of babbling around age 6 months.
