Q

Child Cognition- Early Visual Development

A

At birth we aren’t ready to view the world, and it takes experience to understand the world, with vision. When we are born, we don’t have that many photo receptors and can’t see too much color.

Q

Early Visual Development

A

2-3 months- A child can switch attention. But before this time, the infant stares at whatever is most salient. 6-9 months, can converge or diverge eyes, learns about depth through binocular vision and Gestalt grouping. 9-12 months old, has experienced depth, gravity, and shadows, so after 9 months we have more experience. Ex. Baby visual cliff experiment.

Q

Early development

A

As a result of fetal develop. in the brain, neurons have way too many connections (synapses), and everything is connected with everything (neurotically speaking). So babies don’t know what language their parents speak, so all these connections mean they can learn any language.

Q

Preferential Looking- How we test babies

A

Infants prefer looking at novel and interesting stimuli. The sucking rate means that babies suck on their pacifier if they are interested in something. Gaze duration means they will look at an item that’s new or exciting, and head turning means the infant will turn their head if shown certain stimuli.

Q

Early Brain Development- “Use it or lose it system”

A

Neural pruning is the less we use something, the connections will die off. And the specialization lasts until mid-20s, when we are finished pruning.

Q

Sensorimotor Stage (Stage 1) 0 to 2 years

A

Explores the world through their movements and sensations. Children learn about the world through basic sensations, and actions, such as sucking, grasping, looking, and listening. Learn/realize that their actions have consequences. They are separate beings from the people and objects around them. About age 1, babies learn that things continue to exist even though they cannot be seen.

Q

Object Permanence (gained around age 1)

A

Object permanence means knowing that an object still exists, even if it is hidden. It requires the ability to form a mental representation of the object. For example, if you place a toy under a blanket, the child who has achieved object permanence knows it is there and can actively seek it.

Q

Pre-operational Stage (Stage 2) 2-7 years

A

Children in this stage do not understand concrete logic and cannot mentally manipulate information, so they don’t have conservation. Begin to think symbolically and learn to use words and pictures to represent objects. Ex. a box is a rocket ship, they play pretend. And they are egocentric and struggle to see things from other people’s perspectives.

Q

Early Visual Development

A

We are not born with the ability to see in 3-D (binocular vision), and have to learn about things like Gestalt grouping principles and monocular cues of depth by observing the world around us.

Q

Concrete Operational Stage (Stage 3) 7-11 years

A

Children now understand Conservation, they now begin to think logically about concrete events (but are unable to think hypothetically). Begin to understand hard facts and lose egocentrism. And realize that other people can have different viewpoints and thoughts different from their own. Thinking becomes logical and concrete and organized, their logic is defined by rules and the observations they have learned.

Q

Formal Operational Stage (Stage 4) 12-17 years

A

The ability to use hypothetical and deductive reasoning and abstract concepts, fully achieved around 15 years old. Teens begin to think more about moral, philosophical, ethical, social and political issues that require theoretical and abstract reasoning. Ex. eye placement example, stage 3 kids say eye should be in the forehead, while stage 4 people will have more creative answers, like in the hands.

Genie Wiley

A

Her language acquisition, over the years Genie learned words one at a time, after a few years she could produce 2-word sentences. She was unable to use grammar and surpassed the critical period and was unable to use language.

Q

Bella Devyatkina

A

Bella Devyatkina from Moscow. Her mother was a language tutor and socialized Bella by exposing her to dif. languages through a combination of daily lessons and socializing with people who spoke the foreign languages Bella wanted to learn. So by age 4, able to speak 7 languages, so exposing children to dif. languages is beneficial during the critical period.

Q

Cognitive Development and Illusions

A

As we go through life we acquire experiences with different objects, and make assumptions about our world based on our past experience. Children are not as experienced with the world as adults, so some
illusions operate differently on children versus adults.

Q

Critical Period for Language Acquisition

A

Thought to be active only from roughly birth to
age 12, our brains are primed and particularly
efficient during this time at acquiring and
processing language. For Genie Wiley, she was not properly socialized nor exposed to language during that time period, so she never was able to acquire
language later in life. But Bella Devyatkina has been exposed to many languages within the critical period, so she will likely still be fluent in them decades from
now.

Q

Early Language Acquisition

A

To facilitate the acquisition of new words in very young children, adults use “baby talk” (intonation & pitch changes). This helps the infant with sentence segmentation, pronunciation (by exaggerating changes in prosody), as well as keeping their attention better. This is more effective than adult-directed speech.

Q

Adolescents Online

A

Research has confirmed that children using
technology near bedtime likewise upset their Circadian Rhythms and leads to health issues. So, the hippocampus which is in charge of processing and retrieving memory is affected because the sleep cycle is critical for the formation of processing memories. Memories aren’t encoded and consolidated well because of disrupted sleep.

Q

The Streisand Effect

A

The Streisand effect is a social phenomenon that occurs when an attempt to hide, remove, or censor information has the unintended consequence of further publicizing that information. This effect is an example of psychological reactance, because Barbara Streisand was trying to hide her house.

Q

For all sensory modalities, there is a Presby-word to describe the decline of that modality with age

A

Ex. Presbycusis- Loss of hearing
Presbygeusia: Loss of taste
Presbyopia: Loss of vision
Presbyosmia: Loss of smell
Presbystasis: Loss of balance

25
Aural Anatomy- The Inner Ear
Inner year has cochlear hair cells that vibrate with the vibrations in the fluid and transmit signals to the brain. But cochlear hair cells do not grow back, using earbuds, loud noises and videogames makes people have worse hearing.
26
Presbygeusia- Loss of Gustation (taste perception)
Like the hair cells in our inner ear, we lose our taste receptors over time (a person will have more taste receptors as a child than they will as an adult). This partially explains why children can be “picky eaters,” as their heightened sensitivity to taste sensations (compared to that of an adult) can make many foods particularly unpleasant. As we age, we continue to lose our taste receptors, leading to a marked loss of taste sensations, causing most foods to become more “bland.”
27
Presbyopia- Cataracts
Photoreceptors in eyes decay with age. Macular degeneration is age-related, various cells in retina in you see a grey blob in the middle of your eye and only have peripheral vision.
28
Attention and Memory part 1
Hippocampus slowly atrophies overtime; this means everyone's memory gets worse over time. Sensory memory is affected, which will affect the accuracy of further stages of memory encoding.
29
Attention and Memory in the elderly part 2
Due to slower reaction time and other difficulties with attention, info in short-term memory is less likely to be rehearsed effectively and makes it more likely to be forgotten. And so long-term memories are affected the most, due to a combination of blocking, transience and hippocampal atrophy.
30
Dementia
General term for a decline in mental stability severe enough to interfere with daily life.
31
Alzheimer's Disease
Alzheimer's disease is one type of dementia in which abnormal deposits of plaque and tangled proteins cause the affected neurons to die. Alzheimer's spreads beyond the hippocampus, like the frontal lobe (emotions, planning, decision-making, motor control). Poor sleep is because of Alzheimer's since sleep is the maintenance cycle of the brain, so no sleep makes it worse and a partial cause of Alzheimer's.
32
So as we get older, does everything get worse?
Aside from issues like hearing loss (presbycusis) and reaction time, speech and language are largely intact in the elderly under normal conditions (eg. not suffering from dementia).
33
Spatial Awareness
Children in Piaget's Preoperational stage aren't able to understand this concept yet. And in the elderly, there is also difficulty in these tasks involving spatial awareness.
34
Sensory Memory in the Elderly
Because the senses aren’t relaying fully accurate information anymore due to presbyopia, presbycusis, et cetera, Sensory Memory is affected, which will in turn affect the accuracy of further stages of memory encoding.
35
Short-Term Memory in the Elderly
Due to slower reaction time and other difficulties with attention, information in Short-Term Memory is less likely to be rehearsed effectively (to be passed on to form a Long-Term Memory) and thus is more likely to be forgotten (Absent-Mindedness)
36
Long Term Memory in the elderly
Long-Term memories are affected the most, due to a combination of blocking (more information gathered over a lifetime equates to more blocking occurring), transience, and hippocampal atrophy.
37
Deductive Reasoning
Applying your general knowledge to one specific instance.
38
Inductive Reasoning
Involves taking specific observations and look for the generalization/overall trend.
39
Inductive and Deductive Reasoning in the elderly
Inductive reasoning means identifying patterns, taking new info, and that includes tasks on spatial awareness, which declines with age. While deductive reasoning, (which involves using general knowledge to make specific conclusions) remains stable.
40
Fluid Intelligence (fluid Reasoning)
The ability to deal with new and unusual problems, identifying patterns and problem solving. This includes inductive reasoning and spatial awareness tasks.
41
Crystallized Intelligence (Keeps growing/ deductive)
Acquired knowledge, including verbal knowledge (vocabulary and having expertise in a subject)
42
Social Thinking and Behavior- Obedience
When behavior is influenced due to the commands of an authority figure.
43
The Milgram Study
The teacher subject is led to another room. Where they see the student is hooked up to an electro-shock machine., etc. Basically, these people were confronted with the decision o walk out of the experiment or continue the trial just because a person in a white coat told them to. The results: a vast majority went all the way in the experiment.
44
Conformity
Involves changing one's behavior (subconsciously or consciously) to fit into a group. You aren't thinking logically, you just follow along the group average. Ex. ASCH 1956 study, with the different sized lines.
45
Deindividuation
Loosing ourselves and our critical thinking goes away. when we are alone, we are an individual, but in a social context we are de-individual. This can manifest in aways like social loafing and the bystander effect.
46
Social Loafing
A person in a group tends to exert less effort when combining efforts with others to attain a common goal, than when held individually accountable.
47
Bystander Effect
Individuals are less likely to offer help to a victim when other people are present. The greater the number of bystanders, the less likely it is that any one of them will help. Ex. The murder of Kitty Genovese, murder and abused in front of apartment residents but no none called the police until she was dead.
48
Attitudes- The ABC's of Prejudice, Discrimination and Stereotypes
An attitude is a positive, negative, or mixed evaluation of a person, place, thing or event. They consist of 3 components: Affect, Behavior, and Cognition. * A—Affective (feelings) * B—Behavioral * C—Cognitive (Thoughts/beliefs) Example: Dogs (or cats)
49
A- Affective= Prejudice
A—Affective = Prejudice Negative, unjustified feelings toward a group based solely on their group membership
50
B- Behavioral= Discrimination
B—Behavioral = Discrimination Negative or unjustified harmful behavior based solely on someone’s group membership
51
C- Cognitive= Stereotypes
C—Cognitive = Stereotypes Thoughts/beliefs that associate groups of people with traits
52
The Problem with Intelligence
We have this concept of intelligence but cannot clearly define it, and for this reason we are not very good at measuring it, and yet we put so much emphasis on it, and even utilize it to justify discrimination, cruelty, and murder. Furthermore, we label non-humans (computers, chimps, my dog...) with respect to our already ill-defined notions of intelligence. We like to claim that an animal is “intelligent” if it thinks or behaves like us, but is that really fair to the animal?
53
Anthropomorphism
projecting human qualities onto animals
54
How do humans solve problems?
Algorithms Heuristics Trial and Error Insight
55
Algorithms
A step-by-step procedure that will always produce a correct solution. Ex. mathematical formulas.
56
Heuristics
A mental shortcut that allows people to quickly make judgments and solve problems. These mental shortcuts are typically informed by our past experiences and allow us to act quickly. However, heuristics are really more of a rule-of-thumb; they don't always guarantee a correct solution.
57
Trial-And-Error
Trying a number of different solutions and ruling out those that do not work. This approach can be a good option if you have a very limited number of options available. If there are many different choices, you are better off narrowing down the possible options using another problem-solving technique before attempting trial-and-error.
58
Insight
Also known as the Aha! moment or Eureka Effect)– refers to the common human experience of suddenly understanding a previously incomprehensible problem or concept.
59
Functional Fixedness
A cognitive bias negatively affects a person's ability to problem-solve and innovate. The bias causes a person to look at a problem in one specific way, we limit ourselves because of this.
60
Are animals intelligent?
We don't have an exact definition of intelligence, so this comparison is unfair to animals. Animals evolved to respond to certain unique challenges they faced in their unique evolutionary histories Just because an animal does not think or solve problems in the same way as a human doesn’t mean it is “Unintelligent,” so it’s not really fair to use that word.
61
Testing for Object Permanence
Researchers had dolphins utilize this rolling ball task. Balls don’t roll well underwater, so they had the dolphins poke their head out of the water to watch a ball rolling behind a panel. Dolphins didn't move their heads to anticipate the ball. But once the experiment was made correctly underwater, and flipped the apparatus vertically, the dolphin did correctly look at the bottom to anticipate the ball falling. Showing they do have object permanence.
62
Inductive Reasoning with Animals
Pavlov's Dogs, “Inductive Reasoning involves observing specific trends or patterns, and then generalizing.” The dogs observed specific instances of a bell being rung when food was served. When the bell was rung in the future, the dogs salivated, indicating the dogs had utilized inductive reasoning to make the generalization that bells signal food.
63
Deductive Reasoning with Animals
The experiment: Naïve honeybees who have never foraged observe (through glass) fake/plastic honeybees “foraging” on orange-colored flowers. honeybee version of deductive: Bees go to flowers for food (major premise) The bees are on orange flowers (minor premise) Therefore, orange flowers are food.
64
Can animals speak human-like languages?
No, Animals produce a particular behavior in response to a particular stimulus or ‘noise’, but do not actually understand what the words mean. Animals can still convey an impressive amount of information about the world immediately around them, but lack the ability to communicate abstract concepts (e.g. symbols) which is one of the most important elements of human communication.
65
Talking to Animals- Analog of the Chinese Room
There is a box in which you can ask a question (in Chinese) and afterwards, the box will output a response in Chines. It would seem that the a mechanism in the box understands Chinese. However, that doesn’t have to be true. The person inside doesn’t have to know Chinese at all. This demonstrates that you could ask the man a question in your native language, and he will respond correctly to you in your own native language, even though he has no understanding of what he is saying to you. Ex. Clever Hans or Bunny the Dog.
