Chapter 4: Interacting with the Environment Flashcards
selective attention
the process by which one input is attended to and the rest are tuned out
Broadbent Filter Model of Selective Attention
Inputs from the environment first enter a sensory buffer; one of the inputs is then selected and filtered based on physical characteristics of the input; the information enters short-term memory storage, where semantic processing occurs
cocktail party effect
occurs when information of personal importance from previously unattended channels catches our attention
Trainman’s Attenuation Model
tried to account for the cocktail party effect; rather than a filter, the mind has an attenuator that turns down the unattended sensory input, rather than eliminating it
selective priming
people can be selectively primed to observe something, either by encountering it frequently or having an expectation
spotlight model
the spotlight (attention) is a bean that can shine anywhere within an individual’s visual field; the shifting of attention requires us to unlock the beam from its current target, move the focus, and lock onto a new target
binding problem
the problem of how all these different aspects are assembled together an related to a single object
divided attention
concerns when and if we are able to perform multiple tasks simultaneously
resource model of attention
says that we have a limited pool of resources from which to draw from when performing tasks
What three factors are associated with performance on multi-tasking?
- task similarity (if two activities are similar they interfere with each other)
- task difficulty
- practice
controlled tasks
require flexibility and drain more resources (are typically not multitasked)
working memory
short-term memory
Baddley’s Model of Working Memory
stated that working memory consisted of 4 parts: the phonological loop, the visuospatial sketchpad, the episodic buffer, and the central executive
phonological loop
allows us to repeat verbal information to help us remember it
visuospatial sketchpad
allows us to repeat mental images to help us remember visuospatial information
