Unit 1 (Attention) Flashcards
what is attention
the conscious or unconscious selection of information for cognitive processing
when did interest in attention start
in World War Two, concerning the focus of fighter pilots
can attention capacity change
yes, through factors such as drowsiness which can lower attention capacity
what is involuntary attention
exogenous, or bottom up attention is surprising important and interesting stimuli which captures attention
what is voluntary attention
endogenous, or top down attention is when an individual attends to things of personal importance and reacts to expected signals
what is enhanced processing
filtering out unwanted signals (e.g. classroom noise)
what is diminished awareness
looking but not seeing or listening but not hearing as the stimuli was not selected
types of attention
auditory
visual
spatial
focused
sustained
alternating
divided
what is pre-attentive processing
it refers to the first stage of perception where the brain automatically analyses information before attention is applied
what is attentional gaze
it is like a zoom lens or a spotlight. it reflects where a persons visual attention is attending
describe attentional shifts
they are faster than the eye. they can be caused by social cues (i.e. someone else looking somewhere), goal directed, or driven by salient stimuli
what is change blindness
the inability to notice significant changes in environment, even when they happen in plain sight
what is the cocktail party theory
it explains how individuals can focus their attention on a single stimuli or conversation in a noisy environment
what is selective attention
it allows individuals to focus on specific stimuli while filtering out distractions or irrelevant information
why is the cocktail party effect significant
it illustrates the brains ability to prioritise sensory information, which is crucial for effective communication and functioning in social settings
real life example of cocktail party theory
its like being in a party with multiple conversations and noise going on around you but you are able to focus on the conversation you are engaging in
what is Broadbent’s bottleneck theory
it suggests that information processing is limited by a ‘‘bottleneck’’ which filters out irrelevant stimuli, allowing only certain information to be processed
limitations of cocktail party theory
it may not fully account for how people process and switch their attention between multiple stimuli, like in divided attention or when the ignored message is personally relevant (e.g. name)
how does bottleneck theory operate in context of attention
it suggests that only a certain amount of information can be attended at once, leading to selective attention
real life example of bottleneck theory
a server has to take orders, deliver food, and handle payments. The “bottleneck” occurs at the point where the server can only focus on a limited number of tasks at once.
what is the flexible (Treisman) filter model
it describes how attention acts as a dynamic filter, allowing selective processing of information while still permitting some unattended stimuli to be processed, based on its significance
trainman vs broadbents theories
treismans is more flexible, it suggests that some unattended stimuli can still be processed and that attention can adapt based on context and importance of information
real life example of treismans model
when someone is in a crowded room, engaged in conversation but hears their name across the room and shifts their attention. Despite being focused on one conversation, the significance of their name allowed for unattended information to be processed
what is Norman’s Pertinence model
it emphasises how significance influences the selection and processing of information. it suggests that attention acts as a filter prioritising stimuli based on their meaning to the individual
