the selective aspects of attention, paying attention to some aspects of our environment while ignoring others
A theory that attempts to explain how people select information when some stages of info-processing become overloaded with too much information
A theory that proposed that we have a limited amount of mental effort to distribute across tasks, so there are limitations on the number of tasks we can perform at the same time
Experiment involved three pairs of digits present simultaneously in opposite ears over a period of 1/2 to 2 second intervals. Performance was better at longer intervals
The proposition that a bottleneck occurs at the pattern recognition stage and that attention determines what information reaches the pattern recognition stage.
limited-capacity perceptual channel
The pattern recognition stage of broadbent's filter model which is protected by the attention filter from becoming overloaded with information
Treisman's Attenuation Model
2 parts. a selective filter and a "dictionary" Does not block out information, merely attenuates it
Deutsch-Norman Memory Selection Model
assumed that the bottleneck occurs after pattern recognition, not before. messages are recognized, but only those selected into memory can later be recalled
implies that interference is non-specific and does not depend on the degree to which the tasks use the same mechanisms, but on the total demands of the task. assumes that a person has considerable control over how the limited capacity is allocated to different activities
amount of capacity available varies with the level of arousal, meant to supplement bottleneck theories
A conscious decision to allocate attention to certain aspects of the environment.
A theory that proposes that people's intentions and the demands of the task determine the information processing stage at which information is selected, more capacity is required to perform at a late mode of selection, two lists requires more capacity than one list
A task that typically measures how people can react to a target stimulus to evaluate the capacity demands of the primary task.
when a skill occurs without intention, does not give rise to conscious awareness and does not interfere with other mental activities
Explains the decreased speed of naming the color of ink used to print words when the color of ink and the word itself are of different colors.
tendency of certain kinds of information to enter long term memory with little or no effortful encoding
