Everyday Memory and Memory Errors Flashcards
Define memory.
The process involved in retaining, retrieving and using information about stimuli, images, events, ideas, and skills after the original information is no longer present.
Explain how memories are created by a process of construction.
The construction process is based on what actually happened, combined with other things that have happened, and our general knowledge about how things usually happen.
Define autobiographical memory.
Memory for specific experiences from our life, which can include both episodic and semantic components.
What kind of memory involves mental time travel?
Episodic memory.
Give two characteristics of autobiographical memory.
It is multidimensional, and we remember some events in our lives better than others.
Give the three multidimensional components of autobiographical memory.
Spatial, emotional and sensory components.
What did Greenberg and Rubin find regarding visual memory?
Patients who lost their ability to recognise objects or to visualise objects, due to damage in visual areas of the cortex, also experienced a loss in autobiographical memory.
Why may Greenberg and Rubin have found that visual information plays a vital role in autobiographical memory?
The visual stimuli was no longer present to serve as a retrieval cue.
What part of memory is the hippocampus associated with?
Mental time travel.
What part of memory is the prefrontal cortex associated with?
Processing information about the self.
What brain areas are activated when a person looks at a photo?
The medial temporal lobe and an area in the parietal cortex involved in processing scenes.
What type of memory is the medial temporal lobe associated with?
Episodic memory.
What kind of points in people’s lives are more memorable?
Transition points.`
What is the reminiscence bump?
The enhanced memory for adolescence and young adulthood found in people over 40.
Who proposed the self-image hypothesis?
Rathbone.
Describe the self-image hypothesis.
Memory is enhanced for events that occur as a person’s self-image or life identity is being formed.
What is the cognitive hypothesis?
Periods of rapid change that are followed by stability cause stronger encoding of memories.
Give evidence in support of the cognitive hypothesis.
The reminiscence bump occurs later for people who experienced rapid change later in life.
What does the cultural life script hypothesis distinguish between?
A person’s life story and a cultural life script.
What is a cultural life script?
The culturally expected events that occur at a particular time in the life span.
Explain the cultural life script hypothesis.
Events in a person’s life story become easier to recall when they fit the cultural life script for that person’s culture.
Name three theories that attempt to explain the reminiscence bump.
The self-image hypothesis, the cognitive hypothesis, and the cultural life script hypothesis.
Give some connections between emotional memory and the amygdala. (2)
Amygdala activity is higher upon viewing profane or sexually explicit words, and damage to the amygdala results in normal memory for emotional events, compared to enhanced memory in controls.
What is memory consolidation?
The process that strengthens memory for an experience and takes place over minutes or hours after the experience.
The link between emotion and consolidation was initially suggested by animal research. Explain.
Central nervous system stimulants administered shortly after training on a task can enhance memory for the task, due to the effect of cortisol.
What is released after an emotional experience to increase consolidation of memory?
Stress hormones.
How can emotions impair memory?
Emotions can cause a focus on objects that are particularly important, which decreases memory for other objects.
What is weapons focus?
The tendency to focus attention on a weapon during a crime.
Who proposed the term flashbulb memory? (2)
Brown and Kulik.
Define flashbulb memory.
A person’s memory for the circumstances surrounding shocking, highly charged events, but for the circumstances around how a person heard about the event, not the event itself.
