The four psychological perspectives
What are biological, behavioral, cognitive, and sociocultural?
Energy levels, in an experiment to test intake of water on energy levels.
What is the dependent variable?
Part of the brain involved in the formation of memories
What is the hippocampus?
A type of cell responsible for communication in the nervous system
What is a neuron?
The minimum amount of energy in a sensory stimulus detected 50% of the time
What is the absolute threshold?
The study of behavior and mental processes
What is the definition of psychology?
A sampling technique is which a sample of participants that is representative of the population is obtained
What is random sampling?
A part of the brain where fear is registered
What is the amydala?
A long singular fiber projecting out of the cell body
What is the axon?
The just noticeable difference (JND) between stimuli is proportional to the original stimulus intensity.
What is weber's law?
The perspective taken by a researcher who studies whether it is possible to drive safely while listening to a podcast
What is the cognitive perspective?
Trevor surveyed college students about the number of hours they watched TV in the previous week. He found that most people he talked to watched about 5 - 10 hours per week, but a very small group of students watched around 35 hours per week. To avoid reporting a deceptively high average, he decided to report these other two measures of central tendency.
What is the median and the mode?
The lobe of the brain associated with processing visual information.
What is the occipital lobe?
A disease that includes movement problems resulting from a scarcity of dopamine
What is Parkinson's disease?
These principles demonstrate that the whole is grasped even before the brain perceives the individual parts
What are the gestalt principles?
The perspective taken by a researcher who studies the impact of culture on likelihood of being punctual
What is the sociocultural perspective?
Jodi conducted a survey and found that college students who sleep less than 4 hours a night usually do worse on exams than students who sleep more than 4 hours a night. She is convinced that sleep deprivation causes students to do badly but she knows that this type of study does not allow her to make that claim.
What is a correlational study?
The part of the brain, when damaged, leads to someone being able to understand language but unable to effectively produce a response.
What is Broca's area?
Antidepressant drugs selectively block its reuptake
What is serotonin?
The perceptual stability of the size, brightness and color of objects seen at various angles and distances
What is perceptual constancy?
The participant in the experiment doesn't know if they are taking the new drug or a sugar pill, but the researcher does know.
What is a single blind experiment?
A number between -1 and +1 that describes the relationship between two variables
What is a correlation coefficient?
The strip of cortex in each frontal lobe, that allows us move parts of body
What is the motor cortex?
Division of the nervous system activated when you need to run away from a bear
What is the sympathetic nervous system?
The gestalt principle that the brain organizes sensory info around a center of attention and the less distinct background
What is figure-and-ground principle?
