Selection Flashcards
The fact that salient words (like name, name of a friend, swear words, or words relating to the unattended content) are more likely than others to be detected in the unattended channel is inconsistent with ______ _____.
(Simple) Filter Theory
The gorilla video proves that
Detection of unusual events may be dependent on the amount of effort exerted on the primary task
Problems with Filter Theory (3)
- Distinction between “attended” and “unattended” (filtered) information untenable
- Results imply more complex relation between salience, effort, and details of processing
- Requires a more flexible framework for understanding attention and what it means to be “selected”
4 Assumptions of Resource Theory
- Applied to complex tasks
- Resources are generally non-specific (like knowledge, WM space, etc.)
- Continually available output (some output even if not enough resources)
Resource Theory
Performance is limited by resources. We need more resources to get more done, and at some point more resources won’t help.
Diagonal part of the performance resource slope
Resource Limited
flattening out of the performance resource slope
Data Limited
Paying attention as defined by resource theory.
Adding more resources; a steeper slope= greater efficiency.
When a task is data limited, performance is ______.
automatic
Automaticity means
requiring less resources for a task (less work), but not necessarily doing the task better.
According to resource theory, unattended stimuli will be processed if they are _______.
automatic (explains detecting name in change detection).
->bc resources are largely used up by shadowing task
What is the critical assumption about resources in resource theory?
Performance improves with more resources until the data limit is reached.
