The tendency for people to view themselves as relatively variable in terms of personality, behavior and mood while viewing others as much more predictable in their personal traits across different situations
Worse-than-average effect
The tendency to underestimate one's achievements and capabilities in relation to others
Related to imposter syndrome and is the opposite of the usually pervasive better-than-average effect (Dunning-Kruger effect)
Ultimate Attribution error
We tend to attribute good acts by friends to their character, and bad acts by friends to situational factors
For enemies (or people we dislike), it’s reversed: good acts are attributed to situational factors and bad acts to character
Change bias
Remembering the past as more difficult than it actually was
After exerting effort and causing a change in some area, this bias makes you believe your journey and work were more difficult than they actually were
"When I was a boy... things weren't so easy"
Childhood amnesia
The inability of adults to retrieve memories before the age of two to four years, as well as the period before the age of ten, of which some older adults retain fewer memories than might otherwise be expected given the passage of time
Context effect
An event is more favourably perceived and remembered when the surrounding environment is comfortable and appealing
Cross-race effect
A facial recognition phenomenon in which individuals show superior performance in identifying faces of their own race when compared with memory for faces of another, less familiar race
Fading affect bias
The tendency for memories associated with negative emotions to be forgotten more quickly than those associated with positive emotions
This helps us forget bad experiences more readily
Generation effect (Self-generation effect)
The tendency for information to be better remembered when it is self-generated as opposed to passively consumed
Explains why active recall is one of the most effective learning and retention techniques
Humor effect
The tendency for humorous items to be remembered more easily than non-humorous ones
Potentially explained by the increased cognitive processing time to understand the humor, or the emotional arousal caused by the humor
Lag effect
We retain information better when there are longer breaks between repeated presentations of that information
The lag effect suggests that the longer the time between repetitions of information, the more likely we are to commit that information to memory
Levelling and sharpening
Levelling and sharpening are processes we use during memory recollection
Levelling refers to the tendency to omit minor details and distinctions, whereas sharpening occurs when certain aspects of a memory are exaggerated or made more profound
List-length effect
As the length of a list gets longer, a greater number of items are actually remembered
When you go shopping and forget your list, you remember only a few items—this happens whether it's a short or a long list. If it's long, you'll tend to remember more
Misinformation effect
The tendency for post-event information to interfere with the memory of the original event
For example, if a question contains misleading information, it can distort the memory of an event. This can lead to inaccurate or false memories
Misattribution of memory effect
The tendency to remember what took place and the specific piece of information, but not where it came from
"I've heard about this, but I can't remember where from, so it's hard to justify it"
That's a wrap!

You'll tend to remember more when using a mixed-mode (partly visual and partly auditory) of learning compared to a single-mode (either visual or auditory alone)
When information is presented in multiple modalities, total working memory capacity is increased
Next-in-line effect
The tendency to have lower recall for events that happen right before or after a public performance—whether performing on stage or talking to a group of other people
This effect is believed to occur due to both attention distraction and retrograde amnesia
Describes how, when we are choosing between two alternatives, the addition of a third, less attractive option (decoy) can influence our perception of the original two choices
Distinction Bias
Describes how, in decision-making, we tend to overvalue the differences between two options when we examine them together
Conversely, we consider these differences to be less important when we evaluate the options separately
Occurs when you choose to continue, or discontinue, a behaviour based on the positive or negative reinforcement you've received for that behaviour previously
