PSYCHOLOGY
| Question | Answer |
|---|---|
| correlational study | allow researchers to determine if there is a relationship between two variables |
| myelin sheath | covering of axon |
| weber's law | relationship between stimuli and sensation |
| lens accommodation | the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies |
| action potential | the change in electrical potential associated with the passage of an impulse along the membrane of a muscle cell or nerve cell |
| aphasia | loss of ability to express speech |
| availability heuristic | estimates the likelihood of events based on their availability in memory |
| brocas area | moves the muscles to create speech |
| peripheral nervous system | includes the nerves outside the brain and spinal cord that connects the central nervous system to the rest of the body |
| synapse | very small gaps where neurotransmitters from the terminal buttons and released |
| absolute threshold | our lowest levels of awareness of faint stimuli with no competing stimuli present |
| encoding | taking stimuli fro m the environment and converting it into a form or construct that the brain can understand and use |
| episodic memory | the stories of our lives and experiences that we can recall and tell to someone else |
| just noticeable difference | smallest amount two stimuli had to differ for us to be able to tell them apart |

| heuristic | "rules of thumb" |
| deductive reasoning | an approach to logical thinking that begins with a general idea, such as a hypothesis, and then develops a specific evidence to support or refute it |
| monocular cue | depth perception that cues only one eye |
| excitatory neurotransmitter | when chemicals are released from the terminal buttons, they excite connecting neurons and cause them to fire |
| figure ground | the figure is what is focused on and the ground is the blurry background which is likely ignored |
| explicit memory | past knowledge that is consciously brought to mind |
| availability heuristic | estimates the likelihood of events based on their availability in memory, is another problematic heuristic |
| encoding specificity principal | general principal that matching the encoding contexts of information at recall assists in the retrieval of episodic memories |
| information processing model | receive information |
| Elizabeth loftus | studied memory and how it can have inaccurate attributions |
| mnemonic | device to assist in remembering things |
| George miller | "seven plus or minus two" |
