The other night, the power went out. At first, I couldn't see anything, but my eyes quickly adjusted, allowing me to be able to safely navigate my house.
The perceptual process this scenario describes is known as what?
Dark Adaptation

What does the hormone Ghrelin do?
Increases hunger/can make food seem more appetizing

Teachers may say that students who wait until the night before to study for an exam and then do poorly deserve the grade they got. What social psychology idea would explain this thinking?
Just-World Phenomenon

Bob snores loudly at night. Recently his wife became very worried because she heard him gasping for air and thinks that he even stopped breathing while he was sleeping. What will the doctor probably diagnose him with?
Sleep Apnea.

In a normal distribution, what percentage of the scores in the normal distribution falls within on standard deviation on either side of the mean?
68%

This occurs when two or more lights blink on and off in succession, creating the illusion of movement.
Phi Phenomenon

What kind of information is primarily processed in the temporal lobes?
Sound and language

When I was lifeguarding, someone fell and broke their ankle. I needed a pool guest to call 911, so I specifically said "Laura, please call 911 and then go meet the ambulance outside."
What social psychology phenomenon was I avoiding by specifically asking Laura to call 911 instead of just shouting to all the pool guests, "Someone, call 911?"
Bystander Effect

What is an example of a hypnagogic sensation?
Sensations you experience as you fall asleep, like jerking movements, feeling like you're floating or falling.

Daily Double!!!
A researcher finds that a new study technique improves test scores with a p-value of .03. What does this p-value indicate about the results?
Because .03 is less than .05, the results are statistically significant, meaning the results are NOT most likely NOT due to chance.

After spinning rapidly in place, Maya feels dizzy and has trouble walking in a straight line. Why is she experiencing this sensation?
This sensation occurs because fluid in the inner ear continues to move, bending tiny hair cells.
Further explanation: The hair cells are located in the semicircular canals of the inner ear. When the fluid inside these canals continues to move after spinning, it bends the hair cells, which send signals to the brain about rotational movement.
This ongoing signaling causes the sensation of dizziness and difficulty maintaining balance.

My boss was very happy to take credit for the success of packing extra conference lanyards, even though it was me who anticipated the need. However, when we ran out of notebooks, she quickly made sure everyone knew it was my fault for not packing enough.
What social psych phenomenon is exemplified here?
Self-Serving Bias
(We attribute successes to ourselves and failures to other people or external factors)

Tag in a friend! You can answer this question by yourself and earn 300 points, or tag in a friend, and each of you can earn 150 points.
What part of brain is known to control the circadian rhythm?
SCN (Suprachiasmatic Nucleus)
400
What is effect size?
The strength of the relationship between two variables. The larger the effect size, the more one variable can be explained by the other.
400
Explain absolute threshold.
Absolute threshold is the minimal energy needed to detect a stimulus 50% of the time.
400
What do agonists and antagonists do?
Agonists speed up a neurotransmitter's action; antagonists slow them down.

Tag in a friend: You can choose to answer this question on your own or tag a friend in for help. If you answer it on your own, correctly, you get the full 400 points. If you and your friend answer correctly together, you each get 200 points.
Explain the reciprocity norm.
An expectation that people will help, not hurt, those who have helped them.

What is narcolepsy?
Sudden attacks of sleepiness/falling asleep

A researcher finds a correlation of +0.68 between hours of sleep per night and students’ quiz scores. What does this correlation reveal about the relationship between the two variables, and what important limitation must be considered when interpreting the results?
There is a positive correlation between hours of sleep and quiz scores (the more sleep a student got, the better they did) BUT, the limitation is that this does NOT show causation. There could be other factors impacting quiz scores. Correlation does not equal causation.

Whenever my husband watches basketball, I always text him and ask him to turn down the tv because I hate hearing the noise of the referees blowing their whistles.
Inevitably, he will say he did, and then I'll ask him to turn it down some more.
What psychological/perceptual principle explains why I can't hear the difference the first time?
Difference threshold-- this is the minimum difference required to detect a change in energy between two stimuli 50% of the time. This is known as the JND (Just Noticeable Difference.)
It takes my husband turning the tv down twice for me to perceive a change in volume.
500
What does Substance P do and what can an oversupply cause?
Involved in pain perception and immune response; oversupply can cause chronic pain
500
My friend Bev and I went out in DC back in October and visited a few restaurants as we wandered around. I had driven into the city (paid for gas and parking) so she insisted on paying the first bill for our sodas. What social psych principle is exemplified here?
Reciprocity norm

After two nights without sleep, what can be expected to occur?
REM Rebound (REM sleep increases after REM deprivation)
