Study Notes
Attention Overview
- Attention is the process of selecting and focusing on specific information or stimuli while ignoring others.
- It involves mechanisms that register certain information and reject others, whether or not the rejected information enters conscious awareness.
Selective Attention
- Refers to the ability to focus on one stimulus or message while ignoring others.
- Cherry's dichotic listening and shadowing research (1953) demonstrated that people can focus on one conversation while ignoring others.
- Physical differences such as voice intensity, location, and gender affect selective attention.
- Even when we're not attending to certain information, very little of it is remembered.
Divided Attention
- Refers to the ability to process multiple stimuli or messages simultaneously.
- The dual-task technique is used to study divided attention.
Theories of Selective Attention
- Broadbent's filter model (1958): information is filtered early in the processing stream, and only attended information is processed further.
- Treisman's attenuation model (1964): unattended information is not rejected, but its "volume" is reduced, allowing it to still be processed.
- Deutsch and Deutsch's late-selection filter model (1963): all information is processed, and selection occurs later in the processing stream.
Focused Visual Attention
- Driver (1996): visual attention is similar to auditory attention, but with more opportunities for attending to multiple stimuli.
- Automatic processing: no demands on attentional resources, and unconscious awareness.
- Controlled processing: demands on attentional resources, and conscious awareness.
- Schneider and Shiffrin's automaticity model (1977): tasks can be automatic or controlled, depending on attentional resources.
Visual Search
- Neisser (1967): visual search involves processing simultaneous items, but not fully being aware of them.
- Treisman (1998): focus on stimulus first, and then feature synthesis into a pattern.
- Feature integration theory (Treisman, 1988, 1992): features of objects are separable from the object itself, and are encoded in parallel and prior to attention.
- Visual search tasks: feature search (target has a unique feature) and conjunctive search (target has no unique feature).
Attention Switching
- Visual neglect disorder (Ramachandran; Rogers-Ramachandran, 2009): a disorder of attention where attention is involuntarily captured.
- Involuntary attentional capture: response beyond our control.
- Voluntary attentional vigilance: focus on some particular aspect.
