Introduction
Dr. Green conducts research on how people's brains and behavior changes as they age. They are most likely what type of psychologist?
Developmental
Name the components of a correlation and what they mean
sign:direction
number: strength
The only way to test causation is by using...
What is the function of the hippocampus
Memory
The fovea is primarily made up of ____.
Cones
Your grandma telling a story about her cat is an example of what type of evidence?
Anecdotal
Order the following correlation values from weakest to strongest:
-.78, +.39, +.68, -.22
-.22, +.39, +.68, -.78
Randomly choosing 100 people from a city to participate in a study ensures this process
Random selection
These chemical messengers cross the synaptic gap to influence the receiving neuron.
neurotransmitters
Name 2 differences between rods and cones.
- Rods are good in dim light situations and cones are not
- Cones are good for color vision and specific details
Psychologists who study brain activity linked with thinking, memory, and language are working in this subfield.
Cognitive psychology
Believing that arthritis pain increases during rainy weather is an example of this type of false perception of correlation.
Illusory
In a study, researchers find a positive correlation between coffee consumption and heart disease, but heavy coffee drinkers are also more likely to smoke. In this case, smoking acts as this type of variable.
Third
The division of the autonomic nervous system that prepares the body for fight-or-flight responses.
Sympathetic
The transformation of physical energy, such as light waves or sound vibrations, into neural signals is called this.
Transduction
What is the difference between monism and dualism?
Dualism believes mind and body are two distinct substances. monism thinks they are one substance
What do you need to have in order to establish causality? Why?
Random assignment. Because it equalizes the participant characteristics across groups.
Sam wants to test whether paper color affects math scores. He tests out pink paper, blue paper, and green paper. What is the difference between random assignment and random selection? What might Sam do in his experiment to ensure he has completed both random selection and random assignment?
Random selection is making sure all of the participants have an equal chance of being picked to participate in the experiment. Sam could assign each student a number and use a random number generator to pick who is in his study.
Random assignment is ensuring all participants have an equal chance of being in each group. Similarly, you could randomly assign each student a letter (a, b, c) and have those represent pink, blue, and green paper groups respectively.
John is using which brain lobe to see the baseball in front of him?
Occipital lobe
This system, located in the inner ear, helps maintain balance and orientation in space.
Vestibular
A case study is not good when you want to ____
generalize results
A correlation coefficient of –0.70 between stress and sleep hours tells us this about the relationship.
As stress increases, the amount of sleep tends to decrease. This is a pretty strong relationship.
Stacy wants to test whether carrots improve vision. She randomly selects 40 students and has half of them eat carrots and half of them to not. What kind of study is this? If it is an experiment, what are the IV and DV? The students in this case are considered to be ____.
- Experiment
- IV: eating carrots or not
- DV: vision
- the students are the sample
A split-brain patient shown the word “KEY” in their left visual field will most likely do this when asked to respond.
Grab the key (with their left hand)
According to the opponent-process theory of color vision, we cannot perceive these pairs of colors at the same time.
yellow and blue
green and red
black and white
