PSYCH exam 1 Flashcards
What is the oldest part of the brain
brain stem
what is the portion of the nervous system that includes the brain and spinal cord
central nervous system
All of the following are neurotransmitters
Seretonin, dopamine, and norepinephrine
The difference between sympathetic and parasympathetic
While your sympathetic nervous system controls your body’s “fight or flight” response, your parasympathetic nervous system helps to control your body’s response during times of rest
How can participants affect the outcome of an experiment?
Participants will sometimes second-guess what the researcher is after, or change their answers or behaviors in different ways, depending on the experiment or environment
How does one use systematic observation
The intent is to ensure that, under the same or similar circumstances, all observers will obtain the same results
How can hypothesis be falsified
if it is possible to conceive of an experimental observation that disproves the idea in question
How can a person tell the difference between inductive and deductive reasoning
Inductive reasoning is a bottom-up approach, while deductive reasoning is top-down. Deductive reasoning, you make inferences by going from general premises to specific conclusions
What’s the difference between correlational and experimental designs
In an experimental design, you manipulate an independent variable and measure its effect on a dependent variable. Other variables are controlled so they can’t impact the results. In a correlational design, you measure variables without manipulating any of them
How can experiments help us infer causality
With experiments, researchers actively make changes in one variable and watch for changes in another variable
Why is the peripheral nervous system so important
It plays key role in both sending information from different areas of your body back to your brain, as well as carrying out commands from your brain to various parts of your body
How is the limbic system used in daily life?
The limbic system is the part of the brain involved in our behavioural and emotional responses, especially when it comes to behaviours we need for survival: feeding, reproduction and caring for our young, and fight or flight responses
What causes a person to have adaptations like survival adaptation
An adaptation is defined as a physical or behavioral feature of an animal that helps them better survive in their environment. In other words, an adaptation is something on their body or something they do with their bodies that help them find food, water, mates, and shelter
Why are there still gender roles
they give individuals cues about what sort of behavior is be- lived to be appropriate for what se
How is psychosexual development important to psychology
psychosexual development is a central element of the psychoanalytic sexual drive theory
Describe the process that happens of the synapses between nervous
Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells
Natural Selection
the process through which populations of living organisms adapt and change
Sexual Selection
natural selection arising through preference by one sex for certain characteristics in individuals of the other sex
Error Management
psychological mechanisms are designed to be predictably biased when the costs of false-positive and false-negative errors were asymmetrical over evolutionary history
