Yes, in psychology, "affect" (pronounced AFF-ect) is a noun meaning an expressed emotion. However, in 99% of everyday writing, "affect" is a verb and "effect" is a noun. Stick to the RAVEN rule unless you are writing a psychology paper.
In modern conversational English, "whom" is slowly fading out. However, it is still strictly required in formal, academic, and professional writing. If you can replace the word with "him" or "her," you should use "whom." If you can replace it with "he" or "she," use "who."
Use "fewer" for things you can count (fewer cars, fewer apples). Use "less" for things you cannot count individually (less water, less time). The classic example is the grocery store express lane: it should say "10 Items or Fewer," not "10 Items or Less."
"Its" is a possessive pronoun, meaning belonging to it (e.g., "the dog wagged its tail"). "It's" is a contraction of "it is" or "it has" (e.g., "it's raining"). If you can replace the word with "it is" and the sentence still makes sense, use "it's" with an apostrophe.
"Then" is used for time and sequence (e.g., "we ate dinner, and then we went home"). "Than" is used for comparisons (e.g., "a watermelon is bigger than an apple"). A good trick is to remember that "thAn" compares, and "thEn" tells you whEn.
