Comp. IV Flashcards
cognitive view of learning
a generally agreen upon philosophical orientation
cognitive science
the study of thinking language and increasingly the brain
mirror systems
the areas of the brain that fire both during perception of an action and when performing the action
domain specific knowledge
pertains to a particular task or subject
general knowledge
applies to many different situations
`information processing
takes in information performs operations on it to change its form and content stores the information retrieves it when needed and generates responses to it
sensory memory
stimuli from the environment constantly bombard our bodies mechanisms for seeing, hearing, tasting, smelling, and feeling. the initial processing that trasnforms these incoming stimuli into information so we can make sense of them
perception
the process of detecting a stimulus and assigning meaning to it
bottom up processing
features are extracted or analyzed to five a rough sketch. stimulus must be analyzed into features or components and assembled into a meaningful pattern “from the bottom up”
gestalt
pattern or configuration: refers to peopls tendence to organize sensory information into patterns or relationships
top down
features and patterns detected are combined in light of the context of the situation and our existing knowledge
attention
selective:selected stimuli and ignoring others we limit the possibilities of what we will perceive and process
automaticity
probably a matter of degree; more or less automatic in our performances depending on how much practice we have had, the situation and whether we are intionally focusing our attention and directing our own cognitive processing
working memory
is the workbench of the memory system, the interface where new information is held temporarily and combined with knowledge from long term memory to solve problems or comprehend a lecture.
short term memory
usually means just storage, the immediate memory for new information that can be held about 15 to 20 seconds
central executive
supervises attention, makes plans, and deciedes what information to retrieve and how to allocate resources
phonological loop
a speech and sound related system for holding and regearsing (refreshing) words and sounds in short term memory. It briefly holds verbal information and keeps it active by keeping it in the loop
visuospatial sketchpad
is the place in your mind where you manipulated the image (after your central executive retrieved the meaning of t 180 degrees, and clockwise of course)
episodic buffer
the process that brings together and integrates information from the phonological loop, visuospatial sketchpad, and long term memory under the supervision of the central executive, to create complex memories, such as storing the appearance, voice, words, and actions of an actor in a film to create a complete character
cognitive load
refers to the amount of mental resources, mostly working memory, required to perform a particular talk
intrinsic cognitive load
the amount of cognitive processing required to figure out the material. that amount depends on how many elements you have to take into account how complicated the interaction among the elements are and your level of expertise in problem area
extraneous cognitive load
cognitive capacity you use to deal with problems not related to the learning task, like trying to get your roommate to quit interrupting you or struggling with a disorganized lecture or a poorly written textbook
germane cognitive load
the good cognitive load, because it is directly related to high quality learning: comes from deep processing of relevant information, organizing and integrating the material with what ou already know and forming new understandings
maintenance rehearsal
involves repeating the information in your phonological loop or refreshing information in your visuospatial sketchpad
elaborative rehearsal
involves connecting the information you are trying to remember with something you already know,
chunking
grouping individual bits of information
interference
processing new information interferes or gets confused with old information
decay
if you dont continue to pay attention to information, the activation level decays and finally drops so low that the information cannot be reactivated, it disappears altogether
