When prior exposure to a stimulus has an unconscious influence on our substituent behavior. It is activated by a network of associations in the brain. Ex: If you were to spell feet/feat you would spell whatever version of the word you heard more or more recently.
answer
Priming
question
Stimuli that fall beneath the threshold of conscious awareness. They are too faint, weak, or brief to be consciously affected, and even though we are not consciously aware of them, they can have an effect on our behavior.
answer
Subliminal Stimuli

The theory that effect subliminal stimuli are too small and short lived to be considered valid to our conscious behavior.
answer
Subliminal Persuasion
question
A concentration or focusing of mental activity.
answer
Attention
question
The theory that we only pay attention to one thing rather than another thing. This is used so much so that we normally do not know what else is going on other than that one thing. This is principle is embodied in the cocktail party affect.
answer
Selective Attention
question
Our ability to pay attention to one conversation, even when there are many other conversations going around us. But, even though when you are completely involved in one conversation, you can also hear your name being called out in a distance or in other conversations.
answer
Cocktail Party Affect
question
The idea that when we try to pay attention to two or more things at once, there are limitations to your level of focus. And, the more you try to do at once, the less attentive you are going to be towards a certain thing.

answer
Animals & REM
question
It improves mood, memory, concentration, immune, and bodily functions.
answer
Why do we sleep?
question
Lack of sleep leads to fatigue, irritability, inattention, learning, and hallucinations. It disrupts the immune system, hunger and body fat hormones. It may cause microsleeps. Also, can never really adopt this within a sleep schedule, and your functions are impaired whether you like it or not. You are technically legally intoxicated from this effect.

Often include elements of our waking lives that reflect waking thoughts, concerns, and experiences. It can also consist of things that we are lacking during the day, like if f you were isolate during the day. Your dreams may be more social.
answer
Dream Content
question
Used for for some importance of learning and memory: The time where memories are consolidated and are re-learned. It is also used for emotional stability, like how after a stressed out person wants to sleep.
answer
REM Dreams
question
Used for different purposes than REM, where it involves the re-learning simpler tasks.
answer
NREM Dreams
question
Thought to be the cause of dreaming. Where it is activated by dreams, due to the bursts of activity created in the brain's cortex, from the random activities made throughout the day. The brain, then, tries to make sense of random activation by making up a story for it.

Dangerously amplifies the effects of a drug. Where 1 drug + 1 drug can make 4x the amount of drug effects.
answer
Multiple Drug Interaction
question
In drug abuse and addiction, obtaining that drug almost becomes a person's primary biological need. People also maybe genetically predisposed to develop addiction. Ex: People without dopamine, who do not experience pleasure and reward, tend to seek out what provides the missing pleasure, like addiction, sex, and other things.
answer
Reward-Deficiency
question
Slow things down in the nervous system. Tends to produce relaxation and drowsiness.It produces less anxiety. Ex: Alcohol, Opiate, Benzos
answer
Depressants
question
Depressant that Alters many different neurotransmitters and has a widespread effect on the brain that impairs every aspect of the brain. It impact the frontal lobes, where it creates a lack of inhibitions or decision making. And causes less of an ability to control emotions. It impairs the, hippocampus, that effects memory. The cerebellum's balance and motor control are also effected. Last, it also directly effects the brain stem's reticular formation, where consciousness is distorted. And the brain stem's medulla, that controls heartbeat and breathing. It is known that 50% of drug abuse and crimes arise from this. And produces a serious, deadly withdrawal syndrome for hardcore addicts.
answer
Alcohol
question
Prescription drugs like valium, xanax, librium, et cetera. Also can be found in anxiolytics and tranquilizers. It causes drowsiness and relaxation, where its a GABA agonist, that acts as an inhibitory neurotransmitter.
answer
Benzodiazepines
question
Drug like morphine, heroin, codeine, vicodin, oxycontin. They are Endorphins agonists. They act as pain-killers that induce sleep and euphoria. They are extremely addictive, and withdrawal would create trouble sleeping, and subjects will undergo a lot of pain.
answer

Stimulant that is an adenosine antagonist, that creates wakefulness.
answer
Caffeine
question
Stimulant that is an acetylcholine, DA, NE, opioids antagonist. It is extremely addictive.
answer
Nicotine

An antagonist of dopamine and 5-HT. It may cause damage to serotonin neurons. It creates euphoria, feelings of closeness, and hyperactivity.
answer
MDMA or Ecstasy
question
Psychedelic like LSD, psilocybin, and mescaline or peyote. It works by influencing serotonin. It produce hallucinations, that is exerted by a loss of contact with reality, and it alter thinking and emotions. It also produce euphoria. It has low addiction potentials due to tolerance and is known to have possible therapeutic uses for depression, drug addiction, and PTSD. But these drugs' effects can be unpredictable, and can promote psychosis or loss of contact with reality. It is also known to cause some cases of schizophrenia.
answer
Hallucinogens
question
Its main active ingredient is THC. Its an antagonist to cannabinoid receptors in our body. It alters perceptions, produces relaxation, disinhibition, and creates euphoria. It can disrupt memory, concentration, attention, and motor coordination. It has low toxicity, and that no deaths have been related to it. It has possible medical uses like being therapeutic to pain, nausea, and can act as an appetite stimulant.
answer
Marijuana
question
Technique used to increase a person's susceptibility to suggestion, where it creates a focus based on monotonous stimuli. It is not effective for memory retrieval and drug addiction. It can be effective for treating pain relief, and obesity. It is caused by the placebo effect, where an altered state of consciousness dissociation is created. It is also caused by selective attention to distractions and relaxation. It embodies the role theory, by which a persons complies to the demands of a situation. It is known to have no control over total conscious behavior.
answer
Hypnosis
question
A relatively permanent change in behavior, or knowledge, created through experience. And this practice is strongly associated with behavioral psychology. This practice helps us adapt. Where, the species who have a greater capacity for this, tend to be less controlled by biology, and are more flexible with behavior changes.
answer
Learning
question
We learn by noticing patterns and making associations. And through the embodiment of prediction, like "A" determines "B."
answer
How do we learn?
question
The type of learning where organisms learn to associate between two stimuli. Where, this learnt behavior becomes involuntary. Where that stimulus that produces a response is already associated with another stimulus, that already produces a similar response. It was founded by Ivan Pavlov.
answer
Classical Conditioning
question
A Russian psychologist, earned a nobel prize, who discovered classical conditioning. He based his findings on his Dog Salivation Experiment.
answer
Ivan Pavlov
question
An experiment that that studied how dogs would salivate in anticipation to being fed. Ivan used a bell every time he was about to bring the dogs food. The dogs would then salivate every time the bell rang because the dogs would predict, that when the bell rung, they would be fed. Unconditioned stimulus: Pavlov's dog food; Unconditioned Response: Salvation; Conditioned Stimulus: The bell; Conditioned Response; Salivating to the bell
answer
Pavlov's Dog Experiment
question
Something that naturally creates a response without learning or pairing.
answer
Unconditioned Stimulus
question
The naturally occurring, reflective, automatic reaction to the unconditioned stimulus.
answer
Unconditioned Response
question
The stimulus that has the ability to produce a response, as a result of being paired to the unconditioned stimulus.
answer
Conditioned Stimulus
question
Learned response to the conditioned stimulus.
answer
Conditioned Response
question
Psychologist, who wanted to see is Pavlov's conditioning worked on humans. Specifically, if fear can be conditioned. They experimented this theory on the 9 month baby, Albert. They showed Albert a rat. Then they showed Albert a rat with a loud sound. Albert cried due to the scary sound. Then, Albert became afraid of the rat due to paring the conditioning of the fear, of the sound, with the rat, which became the conditioned stimulus.
answer
Watson & Raynor
question
Acquisition, Biopreparedness, Stimulus generalization, Stimulus discrimination, & Extinction
answer
Processes Involved in Classical Conditioning
question
Learning the relationship between the two stimuli, of the conditioned stimulus and unconditioned stimulus. It works best if the conditioned stimulus comes right before the unconditioned stimulus.
answer
Acquisition
question
The idea that learning a relationship between two stimuli creates a stronger bond if timing is used accordingly. Where, a conditioned stimulus should come immediately before the unconditioned stimulus for the best results.
answer
Predictive Relationship of a Stimulus
question
Something that is biologically predisposed to make particular associations. Ex: Like the common fear of snakes and spiders, which is do to our ancestral traits. We previously feared them in order to survive, and we have then passed down these traits.
answer
Biopreparedness
question
Refers to our tendencies to avoid food prior to getting sick. This happens more commonly with novel foods. Its the theory that takes it only one association between food and an illness to avoid a certain type of food. This relates to bopreparedness and survival traits, because it shows that our ancestors avoided certain foods that they paired as dangerous. It is special type of classical conditioning, because it becomes fixed within our associations, even though it allows for large delay between the conditioned stimulus and the the unconditioned stimulus.
answer
Conditioned Taste Aversion
question
Food we are not familiar with.
answer
Novel Food
question
The tendency to produce a conditioned response, to a stimuli that is similar to a conditioned stimulus. Ex: A dog salivating to the crinkling sound of his dog food as well Pavlov's bell.
answer
Stimulus Generalization
question
The learnt behavior of NOT producing a conditioned response, to stimulus that does NOT signal unconditioned stimulus; Ex: the dog does not salivate to the sound of a phone ringing.
answer
Stimulus Discrimination
question
The learning process that helps us adapt to changing environments. It is the learnt process of getting rid of a conditioned response, by repeatedly presenting a conditioned stimulus without the unconditioned stimulus. Ex: The dog will stop salivating to sound of the bell, if the owner repeatedly whistles before they feed their dog and stops using the bell.
answer
Extinction in Classical Conditioning
question
The learning process of relating an individual's behavior to that behavior's consequences. Where a subject learns to engage in a behavior that leads to a positive consequence, and learns not to engage in a behavior that lead to a negative consequences. This process is voluntary.
answer
Operant Conditioning
question
Shaping, Biological Predisposition, Stimulus Generalization, Discrimination Stimuli, Reinforcement,
answer
Processes involved in Operating Condtioning
question
Classical conditioning is an involuntary learning process, where a subject has no consent in performing a behavior. While, operant conditioning is a voluntary learning process, where association is related to an organism's own behavior towards a stimulus.
answer
Classical Conditioning v.s Operant Conditioning
question
A psychologist who was the founder of shaping. He experimented on rats by using a type of operant conditioning, that involved the shaping of rats' behavior. He invented an "operant box," that involved the gradual shaping of rats' behavior so they learned to press a lever and receive a food reward.
answer
B.F. Skinner
question
The process of reinforcing gradual steps, or successive approximations, in order to create a desired behavior. It involves the uses of learnt complex processing; Ex: Skinner's rats gradually coming to the conclusion that pressing the lever means they will get fed.
answer
Shaping
question
The idea, that influences operant conditioning, and states that it is easier to learn some behaviors in one individual rather than another. This is due to the differences in someone's biological makeup. Ex: How it's hard to train animal to avoid instinctual behaviors, like attacking a prey or marking its territory.
answer
Biological Predisposition
question
The idea, that an organism's particular learnt behavior, will lead to the creation of another another behavior only in the presence of some stimuli, but not in the company of others. Ex: Someone who like to tell jokes, but his jokes are only laughed at while his friends are drunk. He learns to only say jokes when his friends are drunk.
answer
Stimulus Discrimination in Operant Conditioning
question
Signal that a behavior will lead to particular consequence. Ex: The drunk friends who laugh at someone's jokes, only when they are drunk. Therefore, this stimulus creates the particular behavior that someone will not tell a joke until their friends are drunk.
answer
Discrimination Stimuli
question
The idea that occurs when an organism behaves in the presence of the stimulus. Where this stimulus is similar to a previous stimulus that signaled reinforcement. This provides a way of deciding telling us which organisms are capable of understanding or perceiving. Ex: A pigeon getting food when they saw a certain painting. They discriminated that picasso's paintings gave them food and that monet's paintings did not. This generalized the learnt behavior that a painting that looks generally like picasso's gave them food.
answer
Stimulus Generalization in Operant Condtioning
question
A learning process that is defined by the affect it has on behavior. Where it is only seen as this particular process, if it makes the behavior more likely to occur in the future.
answer
Reinforcement
question
Type of reinforcement, that occurs something pleasant or good occurs as a result of a behavior. Ex: Getting rewards like food or getting paid.
answer
Positive Reinforcement
question
Type of reinforcement, that occurs when something unpleasant, or bad, is taken away as a result of a behavior. It often involves the avoidance, or escape, of something bad. Ex: Turning off an annoying alarm to wake up, or repeatedly taking pain medication to when you feel pain.
answer
Negative Reinforcement
question
The idea that timing is important for the process of reinforcement. Where the schedule of reinforcement should be based on either continuous or partial reinforcement. Ex: You should punish your dog during the act of trying to steal a treat, because it is better to enforce reinforcement immediately after a behavior, rather than waiting until you come home to punish, when your dog has already eaten all the treats.
answer
Delay of Reinforcement
question
Reinforcement that helps us adapt to changing environments. It is used to get rid of conditioned responses, by repeatedly presenting the conditioned stimulus without the unconditioned stimulus. Reinforcing through this process does not mean that a conditioned response will stop immediately, but, it will go away through long periods of change. It also reinforces persistence. Last, in order to continue this process, their must be a shift from continuous reinforcement to partial reinforcement
answer
Extinction in Operant Condtioning
question
The theory, that an organism going through extinction, will eventually learn to not be reinforced on every behavior.
answer
Partial Reinforcement Extinction Effect
question
The idea that organisms will learn faster through repeated reinforcement.
answer
Continuous Reinforcement
question
The difference between these two learning processes, depends on the result of a process. Reinforcement, is seen as a more positive approach, and is usually created from a universal stimulus. And a punishment,, is seen as a more positive approach, and is usually created from a discriminative stimulus. But, people normally prefer to use negative reinforcement; like giving candy to a kid having a tantrum.
answer
Reinforcement vs. Punishment
question
A learning process that is defined by the affect it has on behavior. Where it makes a behavior less likely to happen in the future. A common problem with this method, is that it may teach an attention to a discriminative stimulus. It works best through immediacy and consistency, and should be followed by an explanation.
answer
Punishment
question
Someone learns to not do something in front of the punisher. It also doesn't specify a correct behavior, and a punisher may act as a discriminative stimulus. It may reinforcing an attention to a discriminative stimulus, rather than a specific behavior. It also may reinforce fear, anxiety, aggressive behavior like abuse.
answer
Problems with Punishment
question
Adding something unpleasant following a behavior. Ex: Yelling, spanking, et cetera.
answer
Positive Punishment
question
Removing something pleasant following a behavior. Ex: Removing privileges.
answer
Negative Punishment
question
A learning process created through modeling, or from social learning. It is like a cognitive process, where through watching you imitate. The only organisms who have this ability to learn are humans and monkeys.
answer
Observational Learning
question
An experiment, based on observational learning. It involved a group of kids who either watched, or did not watch, videos of adults beating up a Bobo doll. As a result of this viewing, the kids, who watched the video, imitated the adult's violence, and the kids, who didn't watch it, did not act violently.
answer
Bandura and the Bobo Doll Experiments
question
Through correlational and experimental evidence, the kids who spend more time watching TV than they do in school, react more aggressively when provoked. This media violence directly affects behavior and attitudes, and desensitizes the effects of violence and crimes in children.
answer
Media Violence & Observational Learning
question
The retention of information over time. This information is subjective, easily influenced, continually revised, and is influenced by beliefs or expectations.
answer
Memory
question
Known as the man that remembers everything, due to his double photographic memory. He is able to read a page with one eye and a page with the other eye. He was born with brain abnormalities, which allow his brain to make usual connections, and can be shown through his creativity and humor with information. He has a genesis of the corpus callosum, and a larger brain. Inspired the movie "Rain Man."

A type of encoding, where only some of the basic information such as space, time, sequence, and frequency, are encoded into memory. Also, there is no effort made to memorize such information.
answer
Automatic Processing
question
A type of encoding, through the process of repetition and applied meaning.
answer
Effortful Processing
question
Encoding information, involved in effortful processing, through the process of repetition. This type of encoding does not create lasting memory. Only things like phone numbers, and certain parts of sequences will tend to stick.
answer
Maintenance Rehearsal
question
Theory to about how well someone remembers an item on a list. Where it depends on whether something is at the beginning, middle, or end. And that the items at the very beginning, and the ones at the very end, are remembered best. Although, after a duration of time, you tend to remember only the items at the beginning of a list. This is applied in encoding through maintenance rehearsal
answer
Serial Position Effect
question
Idea that we better remember items from the beginning of a list. Part of the Serial Position Effect.
answer
Primacy Effect
question
Idea that we better remember items from the end of a list. Part of the Serial Position Effect.
answer
Recency Effect
question
Encoding information, involved in effortful processing, where through the process of thinking about the meaning of the concepts, that you are trying to remember. Where meaning is semantic, or logical. It involves a deeper level of processing than the process of encoding through repetition. This is because you are linking things to information to things you already know, which is embodied in the self-reference effect.
answer
Elaborative Rehearsal
question
The idea that we are best able to remember information if we apply it to ourselves, where this information becomes personally relevant. This is applied in encoding through elaborative rehearsal.
answer
Self-Reference Effect
question
The idea that we learn information better if learning and decoding is distributed through time.
answer

Information in short-term memory only persist of about 18-30 seconds, unless you are actively using, thinking about it, or rehearsing it.
answer
Duration of Short-Term Memory
question
Stored memory that has an unlimited capacity and a relatively permanent duration. This type of conscious and unconscious memory can also be characterized, as either explicit or implicit. Where explicit memory can be further broken down to episodic and semantic memory. And implicit memory can be broken down to procedural and priming memory.

Type of explicit memory, that stores personal experiences from life and other important events. Ex: Birthdays; Vacations.
answer
Episodic Memory
question
Type of explicit memory, that stores impersonal facts or general knowledge of the world. Ex: Historical facts; State names.
answer
Semantic Memory
question
Type of long-term memory, that is stored without conscious recollection. It typically involves the unconscious influence of past behavior and thinking. This type of memory can be broken down into procedural and priming memory. Also, this type of memory cannot be processed through short-term memory.
answer
Implicit Memory
question
Type of implicit memory, that stores the information involved in knowing how to perform routine skills, or automatic tasks.
answer
Procedural Memory
question
Type of implicit memory, that stores classical conditioning information.
answer

Due to encoding failures within memory; Storage decay; & Retrieval Failure.
answer
Reasons for Forgetting
question
The fading of unused memory.
answer
Storage Decay
question
The idea that information is somewhere in your memory, but you just cannot access it. This is embodied through the idea, that only through the second time of learning information will you truly remember something. This shows that previously learned information is still in you brain, it is just not accessible due to the lack of the of associations your memory made about it.
answer
Retrieval Failure
question
Forgetting is due to Decay and displacement
answer
Reason for Forgetting Short-Term-Memory
question
Forgetting is due to retrieval failure.
answer
Reason for Forgetting Long-Term-Memory
question
A man who would remember long lists of nonsense and test himself of what he remembers. He concluded, that forgetting slows down and levels off. This curve showed that he was more likely to remember things days or weeks later.
answer
Ebbinghaus & The Forgetting Curve
question
Abstract mental frameworks that organize what we know and expect from various situations. It is also where expectation comes from, and develops overtime as we notice more common features. They are built upon previous experiences, and influence how we notice and remember things. Last, they are the things we typically remember the most.
answer
Schemas
question
The theory that we mold information to fit into our schemas.
answer
Schema Theory
question
An experiment, based on the schema theory, that hypothesized that most people are good at remembering the things that are typically in offices. They showed subjects office supplies and asked them to remember things about it. It concluded, that the people who falsely remember things seeing things, are the objects typically found in offices. And that the subjects who were less likely to remember things, used false memories within their schemas.
answer
Office Experiment
question
The idea that misinformation influences our memory. This is due to our memories being easily distorted by questions and suggestions. This is a common issue in eyewitness testimonies.
answer
Misinformation Effect
question
An experiment that asked subject to tell them the speed of how fast a car crash was going. It was asked in two ways: How fast the cars would going when they smashed each other? How fast the cars were going when they came in contact with each other? The one answered more accurately was the one pertaining to the word "smash." She concluded that this difference in data showed that it was due to the different wordings of the question. A week later, she invited back her subjects who gave a more dramatic view on the experiment. This experiment led to the idea that by visualizing and imagining events, people create false memories of things that never happened.

question
Stores long-term-memory, where different memories are created in different patterns of activation within this part of the brain
answer
Frontal & Temporal Lobes's Involvement with Memory
question
Stores classical conditioning memories.
answer
Cerebellum's Involvement with Memory
question
Stores procedural memories.
answer
Basal Ganglia's Involvement with Memory
question
Involves generalized trauma to the prefrontal cortex, where it affects their implicit memory. Patients can't remember events prior to an injury, and generally can't remember parts of the past. Usually people recover their memory in the order from which it actually happened. And a loss of memory that occurs around the time of a loss of consciousness, is memory that cannot be transferred from short-term-memory to long-term-memory. Typically, episodic memory is more severely affected than semantic memory, so that the patient may remember words and general knowledge (such as who their country's leader is, how everyday objects work, colours, etc) but not specific events in their lives.
answer
Retrograde Amnesia
question
Memory damage, caused by damage to the hippocampus. Where patients experience difficulty creating new explicit, long-term-memory. They typically can't remember new information from around 20-30 seconds, this is due to the inability to transfer memory from short-term-memory to long-term-memory. Also, patients usually only lose declarative/explicit memory, but they retain non-declarative or procedural memory. H.M. was a famous case of this brain damage, where he couldn't create explicit memory from around 20 seconds. His implicit memory was not altered, but he couldn't remember events after 1953.
answer
Anterograde Amnesia
question
Manipulating and transforming information.
answer
Cognition
question
Interests includes thinking, knowing, remembering, communicating.
answer
Cognitive Psychologist
question
The idea that we tend to seek out information that confirms our beliefs, and leave out information that we think is wrong.
answer
Confirmation Bias
question
The idea that we cling to our beliefs more if they are challenged. And if we cannot avoid the evidence that suggests our beliefs are wrong, we challenge that evidence. This is due to our overconfidence, where we commonly overestimate our accuracy from our strong belief system.
answer
Belief Perseverance
question
Theory that's principled on the idea that ignorance creates confidence, and states that the people who lack knowledge and skill in an area tend to overestimate their knowledge and skill in that area. Also that that people who do have expertise in that area tend to underestimate their skill.
answer
Dunning-Kruger Effect
question
Characterized by a blend of symbols, words, and characters.
answer
Language
question
The first part of the first year stage in language development. Characterized by a baby's speech pattern, which consists of many discontinuous sounds that can be found in various languages all over the world. Where through time, the languages that are spoken in the infant's household drop out of their speech pattern. And that a baby actually becomes functionally deaf to those languages commonly spoken around them.
answer
Babbling
question
The second part of the first year stage in language development. Where an infant will start using sounds to produce meaning, which is made up of one word at a time. Where an infant will be able to understand more words than they can actually produce.
answer
One-Word Stage
question
Part of the second year stage in language development. Where an infant's speech is characterized by two word sentence formation. And that their sentence structure follows an overgeneralized sense of grammatical rules used in their households. Where, they usually use repetition to get to their point across.
answer
Telegraphic Speech
question
Theory that we are biologically predisposed to acquire language. This theory is backed up by the fast rate of which we learn a language, and the idea that we acquire a language without reinforcement. Also by the critical/sensitive period in a child's development.
answer
Language Acquisition
question
Part of the language acquisition theory. Defined by a window of time in a child's development, where particular forms of speech are used that an adult would not use. Where, if you are not exposed to a language before the age of 7, you not fully not able to acquire a language, and is completely closed off around the age of 13. Also, if you are not exposed to a language, or are deaf and were not exposed to sign language, between this time period, you will never fully understand a language.
answer
Critical or Sensitive Period
question
Children who are not exposed to a language.
answer
Feral Children
question
Thirteen year old girl who was raised with no human contact, other than her abusive father who beat her every time she tried to speak. When she was pulled out of her household she only was able to say her name and sorry. Scientists were interested if she could actually acquire a language. When she was tried to be taught a language she was never able to learn how to grammatically construct a language.
answer
Jeanie: The Feral Child
question
Theory that language influences thinking, where expanding language may expand thinking. This is supported by the idea that we are better able to perceive, think about, and remember a language if we have words for them. Ex: We are better able to learn new colors if we have two or more words for them.
answer
Linguistic Relativity Hypothesis
question
The idea that acquiring different languages will influence the quality of our thought processes. Where we learning more than one language will advance our cognitive flexibility, creativity, and our attentional control on language skills. Ex: People who only speak one language will get different personality results than people who speak more than one.
answer
Billingualism
question
Language that is used to manipulate reality, by making our perception of reality more powerful in order to influence power. Ex: "Liberate" translates to invading.S
answer
Doublespeak
question
