What is Recognition memory?
Process by which you like faces of people you have seen before (recognize), more than novel faces
Ability to correctly distinguish between a previously seen stimulus and a new or novel stimuli
Phenomena by which memories that are retrieved more frequently are more susceptible to corruption by external stimuli
What is the fundamental difference between a Forced-Choice Recognition Test and a Yes-No Recognition Test?
Participants in the Yes-No tests are only ask yes-no questions, compared to the FCRT participants who can be asked a wide range of varying questions
yes-no recognition tests do not yield results testing Retrieval memory, rather test imagination inflation
In a yes-no test shows participants 1 target at a time to gain a yes-no answer to if they have seen it before, while the FCRT shows participants multiple targets at once and participants are required to choose the one they have seen before
What are issues with testing recognition memory? (can choose multiple answers)
Hard to determining exactly what qualifies as good recognition
Impossible to determine what recognition memory really is
Cannot be sure individual participants are just guessing when they are unsure
very few people have the ability to recall/ recognise familiar objects in an experimental setting
What is Signal Detection Theory?
A persons ability to remember commands (such as army signals)
An individuals ability to detect body language of strangers to access situations by generalizing previously determined signals
A model of Recognition theory by which traces in our memory have strength based on their activation level in memory-creates familiarity
A model of Encoding memory that allows individuals to use signals from previously encoded memories to attach new knowledge to the greater knowledge map of the topic
What causes traces (in SDT) to vary in familiarity?
How much attention was paid to it at point of encoding
How many times the original target was repeated
Whether or not an individual likes the target
How similar the target is to everyday objects
Signal Detection Theory assumes new items will be completely novel and have no familiarity
What potential reasons are there for new items having a degree of familiarity?
Items maybe seen frequently outside they experiment, like a table, or a door
Individuals are only guessing answers and not truly paying attention to the test
new items may be similar to items studied
What are possible ways for new items to be less familiar and old items to be made more familiar (bell curves be further apart)
Inform participants at the beginning of the experiment that it is imperative they remember the old items
Increase the amount of time each item is studied during the encoding phase
Increase the number of times an item is studied during the encoding phase
Remove the individuals whose scores dont reflect expected results
