What are the 2 types of processing?
Automatic & Controlled
What type of processing operates independent of subjects' control?
Who theorized the Feature Integration Theory (visual attention)?
What are the 3 main functions of attention?
- Signal detection
- Selective attention
- Divided attention
What kind of attention allocate attentional resources to multiple tasks?
What kind of attention enables one to attend to some stimuli (place is working memory) and ignore others?
What is the ability to maintain a consistent behavior response during continuous and repetitive activity?
Sustained attention (vigilance)
The flexible shifting of focus between tasks requiring different cognitive requirements.
What is actively searching a target?
What theory posits that as the similarities between target and distracter stimuli increase, so does difficulty in detecting target?
What are the 3 processes of selective attention?
- 1) Pre-attentively analyze the properties of the stimuli
- 2) Analyze if the stimuli has a pattern (speech)
- 3) Focus attention on the stimuli and evaluate it/assign it meaning
What model states that highly salient messages may break through selective attention filter?
Moray's Selective Filter Model (Early Selection)
What are the two parts of the Guided Search Theory?
- 1) Parallel
- 2) Serial stage
What theory contends that stimuli is filtered to limit quantity of info we pay attention to?
Bottleneck theories of selective attention (Late Selection)
What theory states the following:
a) Movement enhances visual research when features are distinctly different
b) Movement hinders visual search when feature differences are subtle?
Movement Filter Theory
What theory posits that all searchers (feature/conjunction) involve 2 consecutive stages of parallel & serial stage?
Guided Search Theory
What theory claims the following:
a) Information is filtered right after it is registered at the sensory level
b) Multiple channels of sensory input reach an attention filter that only permits 1 channel to reach perception
c) in addition to target stimuli, stimuli with distinctive sensory characteristics (loud) may also pass through attentional filter?
What are the 3 factors that improve our ability to attend to one (of 2) auditory stimuli?
- a) Distinctive characteristics of target's speech (high, low, rhythmic pacing)
- b) Sound intensity
- c) Location of the sound source
What model asserts that we possess a signal-weakening (attenuating) mechanism to weaken the strength of non-target signals?
Treisman's Attenuation Model
What are the different kinds of attention responsible for binding different features into consciously experienced whole?
- a) Divided attention
- b) Focused attention
