- long term memory capacity is essentially unlimited. Memories are not stored intact in the brain in single spots. Many parts of the brain interact as we encode, store, and retrieve memories

Why did you choose an experimental design rather than a correlational design to test this research question?

An experimental design allows us to determine what causes false memories, rather than just learning about relationships between memory-related variables.

If someone asks you whether our memory is accurate, how might you respond based on what you learned in this activity?

We've learned that memory is in fact not always accurate. We sometimes make the mistake of thinking we remember seeing words that we did not actually see. We tend to form false memories when we see a word that is related to a list of words we saw, but wasn't actually on that list.

Memories tend to be unreliable for things that occurred at very young ages (before age 4), and when constructed long afterward with suggestions implanted during hypnosis or therapy.

Research has proven which of the following statements to be untrue?

Memory in the brain works like memory in a computer; we take in information and then file it away for recollection.

_____ can be defined as the persistence of learning over time through the storage and retrieval of information.

Memory

_____ interference is the disruptive effect of prior learning on the recall of new information.

Proactive

It's often supposed that people repress memories of trauma, to banish the pain. How does evidence support or challenge this idea?

The available evidence challenges this idea, indicating that people seldom forget traumas, and are instead much more likely to be haunted by intrusive memories.

proactive interference

The reverse direction of interference to retroactive interference. This is when old information prevents the recall of newer information.

You chose to measure whether participants recalled words they saw and words they had not seen. Why?

This provided measures of recall accuracy and whether participants had a false memory.

By using an experimental design, you could determine whether seeing some words, but not others, caused some participants to have:

a false memory.

Long-term potentiation (LTP) refers to

an increase in a cell's firing potential.

the biomolecular process that your neurons go through as you learn, how connections between neurons are strengthened through repeated pairing / firing neurons that fire together. wire together (through LTP) macro changes after LTP (repeated simulation of neurons)

When we place ourselves in the physical space our original learning process occurred, we prime ourselves to more readily retrieve memories that were encoded in the same space. This is called:

the encoding specificity principle.

22. When tested immediately after viewing a list of words, people tend to recall the first and last items more readily than those in the middle. 22. When retested after a delay, they are most likely to recall

the first items on the list.

sensory memory

the immediate, initial recording of sensory information in the memory system. 2, 1/2 seconds

An attorney uses misleading questions to distort a court witness's recall of a previously observed crime. This BEST illustrates:

the misinformation effect.

priming

(Implicit Memory) change in stimulus processing due to prior exposure to same or related stimulus without conscious awareness.

What is our short-term memory capacity?

- (STM) holds five to seven items for about 15 to 20 seconds.

Why do we forget?

- Anterograde amnesia is an inability to form new memories. Retrograde amnesia is an inability to retrieve old memories. Normal forgetting can happen bc we have never encoded info (encoding failure); bc the physical trace has decayed (storage decay); or bc we cant retrieve what we have encoded and stored (retrieval failure. Retrieval problems may result from proactive (forward acting) interference, as prior learning interferes w recall of new info, or from retroactive (backward- acting) interference, as new learning disrupts recall of old info. Motivated forgetting occurs, but researchers have found little evidence of repression.

Eliza's family loves to tell the story of how she "stole the show" as a 2-year-old, dancing at her aunt's wedding reception. Even though she was so young, Eliza says she can recall the event clearly. How is this possible?

- Eliza's immature hippocampus and lack of verbal skills would have prevented her from encoding an explicit memory of the wedding reception at the age of two. It's more likely that Eliza learned information (from hearing the story repeatedly) that she eventually constructed into a memory that feels very real.

How do explicit and implicit memories differ?

- Explicit memories are those we are consciously aware of and can recall intentionally. Implicit memories are those that are not conscious and we do not deliberately remember or reflect on.

How do external cues, internal emotions, and order of appearance influence memory retrieval?

- External cues activate associations that help us retrieve memories; this process may occur without our awareness, as it does in priming. ... Anterograde amnesia is an inability to form new memories.

What is memory, and how is it measured?

- Learning that has persisted over time, through encoding, storage, and retrieval of info. Evidence of memory may be seen in an ability to recall info, recognize it, or relearn it more easily on a later attempt.

How do changes at the synapse level affect our memory processing?

- Long-term potentiation (LTP) appears to be the neural basis of learning. In LTP, neurons become more efficient at releasing and sensing the presence of neurotransmitters, and more connections develop between neurons.

How do psychologists describe the human memory system?

- Psychologists use memory models to demonstrate memory. Information-processing models involve three processes: encoding, storage, and retrieval. Our brain processes many things simultaneously (some of them unconsciously) because of the process parallel processing

How does sensory memory work?

- Sensory memory feeds information into working memory for active processing. An iconic memory is a brief (a few tenths of a second) memory of visual stimuli. an echoic memory is a three/four second sensory memory of auditory stimuli.

What roles do the cerebellum and basal ganglia play in memory processing?

- The cerebellum and basal ganglia are parts of the brain network in order to help out implicit memory formation. The cerebellum is important for storing classically conditioned memories. The basal ganglia are helping in motor movement and help form procedural memories for skills. Many reactions and skills learned during our first three years continue into our adult lives.

What roles do the frontal lobes and hippocampus play in memory processing?

- The frontal lobes and hippocampus are parts of the brain network dedicated to explicit memory formation. Many brain regions send information to the frontal lobes for processing. The hippocampus registers and temporarily holds elements of explicit memories before moving them to other brain regions for long-term storage.

How do misinformation, imagination, and source amnesia influence our memory construction? How do we decide whether a memory is real or false?

- When we reassemble a memory during retrieval, we may successfully retrieve something we have heard, read or imagined, but attribute it to the wrong source (source amnesia). False memories feel like true memories and are equally durable. Constructed memories are usually limited to the gist of the event

Children can be accurate eyewitnesses if

- a neutral person asks nonleading questions soon after the event.

How reliable are young children's eyewitness descriptions?

- childrens eyewitness descriptions are subject to the same memory influences that distort adult reports. If questioned soon after an event in neutral words they understand, children can accurately recall events and ppl involve in them.

The concept of working memory

- clarifies the idea of short-term memory by focusing on the active processing that occurs in this stage.

Why have reports of repressed and recovered memories been so hotly debated?

- debate focuses on whether memories of early childhood abuse are repressed and can be recovered during therapy. unless the victim was a child too young to remember, such traumas are usually remembered vividly, not repressed. Psychologists agree that childhood sexual abuse happens. Injustice happens forgetting happens recovered memories are common. memories of evets that happened bf age 4 are unreliable; memories recovered under hypnosis are especially unreliable; and memories, whether real or false, can be emotionally upsetting

What are the levels of processing, and how do they affect encoding?

- depth of processing affects long term retention. In shallow processing, we encode words based on their structure or appearance. Retention is best when we use deep processing, encoding wrds based on their meaning. We also more easily remember material that is personally meaningful- The self reference effect.

How do emotions affect our memory processing?

- emotional arousal causes an outpouring of stress hormones, which lead to activity in brains memory forming areas. Significantly stressful events can trigger very clear flashbulb memories.

The psychological terms for taking in information, retaining it, and later getting it back out are _______________, _________, and___________ .

- encoding, storage, retrieval

What information do we process automatically?

- in addition to skills and classically conditioned associations, we automatically process incidental info ab space, time, and frequency.

The hour before sleep is a good time to memorize information, because going to sleep after learning new material minimizes _________________ interference.

- retroactive

One reason false memories form is our tendency to fill in memory gaps with our reasonable guesses and assumptions, sometimes based on misleading information. This tendency is an example of

- the misinformation effect

Some individuals have an amazing ability to remember things. For example, college student Feng Wang could repeat back _____ digits.

200

After a week of being asked about the false photo, what percent of students recalled having had a hot-air balloon ride?

50

Imagine a study in which participants are shown 2000 slides of houses and storefronts, each for only 10 seconds. Later, these same participants are shown 300 of the original slides paired with slides they have not seen before. According to research, these participants would be able to recognize _____ percent of the slides they had seen before.

90

retrograde amnesia

; cannot remember events prior to brain damage

mood-congruent memory

the tendency to recall experiences that are consistent with one's current good or bad mood.
