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
episodic buffer
occurs when information in the working memory can interact with information in long-term memory
central executive
orchestrates the process of working memory by shifting and dividing attention
Piaget’s Theory of Cognitive Development
- Sensorimotor Stage (birth to 2 years)- babies experience the world through their senses and movement; they learn object permanence; they demonstrate stranger anxiety
- Preoperational Stage (ages 2 to 7)- children learn that things can be represented by symbols, such as words or images; the lack logical reasoning; they are egocentric
- Concrete Operational Stage (ages 7 to 11)- children learn to think logically about concrete events; they learn the principle of conservation
- Formal Operational Stage (ages 11 to adulthood)- people learn from abstract reasoning and moral reasoning
recall
retrieving information from memory without any clues
recognition
retrieving information from memory with clues
heuristics
mental shortcuts
confirmation bias
the tendency to search only for information that confirms our preconceived thinking, rather than information that might not support it
fixation
an inability to see a problem from a fresh perspective
mental set
a tendency to fixate on a solution that worked in the past, though it may not apply to the current situation
functional fixedness
a tendency to perceive the functions of objects as fixed and unchanging
representativeness heuristic
a tendency to judge the likelihood of an event occurring based on our typical mental representation of those events (Ex-we tend to believe that more people die from shark attacks than from vending machines)
availability heuristic
a tendency to make judgments based on how readily available information is in our memories
belief bias
the tendency to judge arguments based on what one believes about their conclusions rather than on whether they use sound logic
belief perseverance
a tendency to cling to beliefs despite the presence of contrary evidence
