Facts or Falsehoods: Memory
1. Memory storage is never automatic, it always takes effort.2. When people go around a circle saying their names, their
poorest memories are for what was said by the person just before them.
3. Memory aids are no more useful than simple rehearsal of information.
4. Only a few people have photographic memory.5. Although our capacity for storing information is large, we are
still limited in the number of memories we can form.6. When people learn something while intoxicated, they recall it
best when they are intoxicated again.7. The hour before sleep is a good time to commit information to
memory.8. How confident eyewitnesses are about what they saw is an
important predictor of their accuracy.

Memory- the persistence of learning over time through the encoding, storage and retrieval of information.
Pulling information from storage
“Holding on” to encoded information
Converting environmental & mental stimuli into memorable brain codes
Memory Concepts Information must be encoded, stored, and retrieved. Psychologists have offered several information-processing models of memory. One is connectionism, which views memories as emerging from interconnected neural networks.
Retrieval Storage
Encoding
Parallel processing- the processing of many aspects of a problem simultaneously
Theory# 1 Three-stage Processing Model of MemoryThe Atkinson-Shiffrin three-stage processing model states that we first record to- be-
remembered information as a fleeting sensory memory, from which it is processed into short- term memory, where we encode it through rehearsal for long-term
memory and later retrieval.
Three-stage Processing Model of Memory
Problems with the three-stage model
1. Some information skips the first two stages and enters long-term memory automatically.
2. Since we cannot focus all the sensory information in the environment, we select information (through attention) that is important to us.
3. The nature of short-term memory is more complex.
8
Theory # 2: Working Memory Model (Baddeley) This is a newer and better understanding of short-term memory
because it emphasizes a more active role in the second processing stage in which information is rehearsed, new stimuli are associated
with existing memories, and problems are solved. The working-memory model includes the processing of incoming visual-spatial and
auditory information.

• Developed by Alan Baddeley in the 1970s
• The key is the Central Executive
• Takes into account the complexities of memory
How We Encode (Acquire Information)Automatic processing occurs without our awareness and without interfering with our thinking about other things. Some forms of processing, such as learning to read or drive, require attention and effort when we first perform them but with practice become automatic. Automatic processing occurs unconsciously; effortful processing requires attention and effort. For example, our memory of names will disappear unless we rehearse them.
Automatic Processing- Space: location of items- Time: sequence of the day’s events- Frequency: how many times things have happened
Effortful Processing- Maintenance Rehearsal:
- Simple Repeating keeps it STM- Elaborate Rehearsal:
- Thinking & Making connections to other learned ideas
10
Serial Position Effect-is our tendency to remember the last and first items in a long list
• Primacy Effect– Recall items better at the beginning of the list– Better in the long run
• Recency Effect– Recall items better at the end of the list– Better in the short term

Created by the father of memory:Hermann Ebbinghaus (know his name!)
Other Issues in EncodingNext-in-line Effect - Tend to not recall information of person before your turn in
line because you focus on our own performance
Spacing Effect (Distributed Guided Practice) - We retain information better when it is distributed over time - Spread out our learning (cramming = dump and forget)
12
Spacing Effect• Ebbinghaus’s Forgetting Curve
How We Encode
- Visual Encoding (imagery) - Acoustic Encoding (sounds) - Semantic Encoding (meaning)
* We can recall information we can relate to ourselves (self-reference effect)
14
Using Mnemonic Devices to Encode
MNEMONIC DEVICESMemory aids that use organizational devices or imagery to recall memories1. METHOD OF LOCI- Imagine walking through familiar locations and linking each place with what is
to be remembered; used by actors to remember lines (we will watch a video on this the last few minutes of class)
2. PEG-WORD- Remember a list through a jingle, both visual and acoustic (1- bun, 2- shoe, 3-
tree)3. ACRONYMS* HOMES = Huron, Ontario, Michigan, Erie, Superior• ROY G. BIV = Red, Orange, Yellow, Green, Blue, Indigo, Violet4. CHUNKINGCluster information into familiar, manageable units, such as words into
sentences. Chunking occurs so naturally that we often take it for granted.

Storage & Brain Changes
Synaptic Changes- Long-Term Potentiation (LTP) refers to synaptic enhancement after learning. An increase in
neurotransmitter release or receptors on the receiving neuron indicates strengthening of synapse.Stress Hormones-Cortisol - Heightening emotions (stress-related or otherwise)
make for stronger memories. Continued stress may disrupt memory.
Hippocampus- Neutral center in the limbic system that processes
explicit memories.- Damage to the Left: verbal information- Damage to the Right: visual design & locationCerebellum- Neural center in the hindbrain that processes implicit memories.

3 Sins of Forgetting
• Absent-mindedness—inattention to details leads to encoding failure (our mind is elsewhere as we lay down the car keys).
• Transience—storage decay over time (after we part ways with former classmates, unused information fades).
• Blocking—inaccessibility of stored information (seeing an actor in an old movie, we feel the name on the tip of our tongue but experience retrieval failure—we cannot get it out).

3 Sins of Distortion

• Suggestibility—the lingering effects of misinformation (a leading question—“Did Mr. Jones touch your private parts?”—later becomes a young child’s false memory).
• Bias—belief-colored recollections (current feelings toward a friend may color our recalled initial feelings).

Rehearsal
• Maintenance rehearsal- a type of memory rehearsal that is useful in maintaining information in short term or working memory.
This is not an effective way of having information processed and transferred into long term memory. This type of rehearsal usually involves repeating information without thinking about its meaning or connecting it to other information. This is why the information is not usually transferred to long term memory
• Elaborative rehearsal -a type of memory rehearsal that is useful in transferring information into long-term memory
This type of rehearsal is effective because it involves thinking about the meaning of the information and connecting it to other information already stored in memory. It goes much deeper than maintenance rehearsal

Concepts
• Formal concepts - defined by specific rules or features
• Natural concepts - form as result of real world experience (fuzziness)
• Prototype - example of concept that closely matches defining characteristics

Concepts v. Prototypes
• Concept: The mental grouping of similar objects, events, ideas, or people. There are a variety of chairs but their common features define the concept of a chair.
• Prototype: Best example of a concept– we form concepts with mental images or typical
examples (prototypes). For example, a robin is a prototype of a bird, but a penguin is not.

Types of Thinking
• Convergent Thinking: Deliberate, purposeful thinking that is useful for solving problems with only one correct solution
• Divergent Thinking: also known as creative thinking, it follows no set plan and is more useful for solving problems that have multiple solutions in different directions.
• Metacognition: Thinking about thinking. Example: thinking about your strategy to solve an algebra problem

Problem-Solving
• Problem solving – cognition used to reach goal by thinking/behaving in certain ways– Trial and error – one
possible solution after another tried until successful
– Algorithms – specific steps for solving certain problems
– Heuristics – guess based on experience (“rule of thumb”)

Problem Solving
• Algorithms: Methodical, logical rules or procedures that guarantee solving a particular problem.– Algorithms, which are very time consuming, exhaust
all possibilities before arriving at a solution. Computers use algorithms.

Insight & Incubation
• Insight: involves a sudden novel realization of a solution to a problem. Humans and animals have insight.– Example: Wolfgang Kohler & Sultan
the Ape• Incubation Effect: Walking away
from the problem only to have insight set in
• Brain imaging and EEG studies suggest that when an insight strikes (the “Aha” experience), it activates the right temporal cortex
• The time between not knowing the solution and realizing it is 0.3 seconds.

How do we make decisions using heuristics?
• Heuristics are simple, thinking strategies that allow us to make judgments and solve problems efficiently. Heuristics are less time consuming, but more error-prone than algorithms. (AKA- Rules of Thumb or Shortcuts)– Representativeness Heuristic: Judging the
likelihood of things or objects in terms of how well they seem to represent, or match, a particular prototype.

• Representativeness Heuristic (con’t)– Tom W. is of high intelligence, although lacking in true creativity. He has a
need for order and clarity, and for neat and tidy systems in which every detail finds its appropriate place. His writing is rather dull and mechanical, occasionally enlivened by somewhat corny puns and by flashes of imagination of the sci-fi type. He has a strong drive for competence. He seems to feel little sympathy for other people and does not enjoy interacting with others. Self-centered, he nonetheless has a deep moral sense."

Language Structures
• Phonemes: The smallest distinct sound unit in a spoken language. For example: t, ch (40 in the English lang.)
• Morpheme: The smallest unit that carries a meaning. It may be a word or part of a word. (Ex. –ed, un-, s)
• Grammar: is the system of rules in a language that enable us to communicate with and understand others.– Syntax: consists of the rules for combining words
into grammatically sensible sentences– Semantics: is the set of rules by which we derive
meaning from morphemes, words, and sentences.

Language Development Theories
1. Operant Learning: Skinner (1957, 1985) believed that language development may be explained on the basis of learning principles such as association, imitation, and reinforcement.
2. Inborn Universal Grammar: Noam Chomsky (1959, 1987) opposed Skinner’s ideas and suggested that the rate of language acquisition is so fast that it cannot be explained through learning principles, and thus most of it is inborn. Language Acquisition Device. Chomsky says that all children need to learn language is to be introduced to it
Based on the ideas above, answer the following:1.Who views language from the nature perspective? Nurture Perspective?2.In a debate, who would argue the point, “ Children make up new sentences without hearing them first”3.In a debate, who would raise the question, “How does the LAD work, where is it located?”

Thinking and Language
• Linguistic Determinism: Whorf (1956) suggested that language determines the way we think. For example, he noted that the Hopi people do not have the past tense for verbs. Therefore, the Hopi cannot think readily about the past.
• Some cultures count: 1, 2, many…
When a language provides words for objects or events, we can think about these objects more clearly and remember them. It is easier to think about two colors with two different names (A)
than colors with the same name (B)112
