The cue-depending forgetting theory states that people tend to fail to recall memories without memory cues which can be:
semantic (same category group of words),
state dependent (depending on the state of mind we had when we acquired the information)
or context dependent (depending on the context where we usually perceive the information)
In this example, Dr. Rogers can not recall the name of her student when he sees her at the mall but when he sees her in class he immediately recalls her name. This is a cue-depending forgetting where the cue was dependent on the context (classroom), this theory would explain why outside of the classroom he couldn't remember her name.
People's opinions, tastes, and values differ. These are oall influence on how they see the good and bad in all the outcames that they are faced with. People face different situations like wealth and income or age and gender, that affect how they calculate the worth of things.
