TB8 - Cognitive Learning Flashcards
What would cognitive psychology say a “concept” is?
Concepts are general ideas that allow us to organise objects, events etc on the basis of some similarity.
What is the nativist argument for how we acquire concepts?
We are already born with some concepts
What is the empiricist argument for how we acquire concepts?
Concepts are only gained and formed via experience
How are categories formed?
Perceived similarities, associative learning or language/symbolic representation.
What does Rosch (1970) argue about learning concepts?
Basic levels are acquired first then we develop the concepts of super-ordinate or sub-ordinate categories.
For example, we would learn what a dog is, then learn more about smaller groups such as poodle, or larger groups like mammals.
Who argued that we acquire knowledge of basic levels (dog) before learning about super-ordinate (mammals) or sub-ordinate (poodles/bulldog etc)
Rosch (1970)
What did Bornstein and Arterberry (2010) argue about learning concepts?
We start by learning the super-ordinate (mammal), then develop more selection about basic (dog) categories and ordinate (poodle/bulldog etc) categories
Who argued that we start by learning concepts of super-ordinate categories, then develop concepts of basic and sub-ordinate categories?
Bornstein and Aterberry (2010)
Which belief about the development of concepts is more likely to be correct?
Bornstein and Aterberry (2010)
What is prototypicality?
How close something is to the typical idea of a category
What is the measure of how close something is to the typical idea of a category, and what is something that matches this idea called?
Prototypicality
Prototype
What is abstraction?
Filtering out information and selecting only that needed for a purpose/specific category.
For example abstracting a football so that it is only generalised as a ball.
What does the visual comparison test do?
It allows us to see what infants can distinguish between
Which test allows us to see what infants distinguish between?
The visual comparison test
What did Quinn, Eimas and Rosenkrantz (1993) do and find?
Familiarised infants to pictures of one kind of animal, then shown that animal alongside another. The infants look much longer at the one they haven’t seen before, so have habituated to the first animal.
At what age do we believe infants can use perceptual information to create abstract categories?
3 months old
What perceptual cues can infants use to form categories?
Basic visual features(shape, colour size)
Higher level visual features (spatial configuration)
Auditory cues (voice, phonetics)
Other perceptual cues (Touch/texture)
What did Pauen (2002) do and find?
Infants were exposed to animal toys. When introduced to a new animal toy they showed a small novelty effect and played with it more. However, when introduced to a toy from a new category completely (Eg: car) they played with it even more, showing a large novelty effect. The same effect was seen when the reverse occurred and the animal was from the new category of toys.
What are the ages and stages that development occurs in hidden object searching?
0-8 months: No search
8-12 months: Search for moved object in original location
12-18 months: Can find an object moved in front of them, but can’t track objects that change locations out of sight
18-24 months: Full object permanence/tracking
What do Meltzoff and Borton (1977, 1979) find evidence for?
Neonates can combine different modalities of perception as they can infer things from texture and imitate motor movements from vision.
Who found evidence for neonates inferring things from texture and imitating movements from seeing them?
Meltzoff and Borton (1977, 1979)
Then did Baillargeon (1987) find evidence for?
Infants can represent hidden objects even if they do not search for them.
Who found evidence for infants being able to represent hidden objects?
Baillargeon (1987)
What do nativists say we have knowledge about from birth (core knowledge)?
Objects
Actions
Numbers
Geometry
With regards to object knowledge, what is cohesion?
This is when objects move as connected and bounded wholes.
Infants will believe that two objects moving together are a whole.
With regards to object knowledge, what is continuity?
Objects can move on connected, unobstructed paths.
With regards to object knowledge, what is continuity?
Objects influence each other through contact
What did Gergleu, Bekkering and Kiraly (2002) find with regards to core action knowledge?
Adults turned a light on using their forehead. Infants were given the chance to imitate. If the adults’ hands were free then the infant would also use their forehead, but if the adults’ hand were restrained the infant would use their hands.
This suggests that the infants are considering the “why” of an action.
What did Izard (2009) find with regards to core number knowledge?
Infants could tell when numbers matched. For example, when played 16 sounds they looked longer at a presentation of 16 objects rather then a presentation of 4 objects, but switched when hearing 4 sounds.
When did Gouteux and Spelke (2001) find with regards to core geometrical knowledge?
Children can find objects using spatial cues, but only with large scale geometry like length of the wall as supposed to using specific objects like wall hangings.
List constraints of the nativist perspective.
It is difficult to measure exactly what is innate - when it emerges as behaviour cannot be a direct indicator of whether it is or isn’t innate.
It is difficult to understand how perceptual experience can change or shape innate qualities
It is hard to answer WHY something might be innate
What did Plunket (2008) do and find with regards to semantic information and categorisation in infants?
He created different groups of abstract animals. They were categorised based on features such as leg length, arm length, body size etc
In different experiments, children were habituated to different groups of these animals. When new groups were introduced, a novelty effect was seen.
What did Waxman (1990) find with regards to syntactic information and categorisation in infants?
Children were given words, and then shown photos of categories (such as animal, clothing and food). The children had to select the photo closest to the word they were given.
Children were better at categorising with nouns than with adjectives, suggesting nouns are associated with a superordinate category.
Children were better at categorising adjectives with subordinate categories.
Children use syntax when categorising.
What are the basic assumptions of the information processing perspective?
There is a limit to how much information we can process at once.
A written sentence may come in via the input, this will then be attended to, transformed into a mental representation and assigned meaning. The output will then be motor behaviour, or a decision, or a long term memory store.
How can our information processing change as we age?
Children’s brains mature as they age, which leads to advances in input, output and information processing.
How can we study memory in preverbal infants?
If they show a novelty effect between two pictures this suggests they have stored one of them in memory
How can operant conditioning be used to test whether pre-verbal infants have developed memory?
Infants showed the ability remember that kicking a mobile would make it move, therefore pleasing them.
Which factors affect the encoding of memories in infants?
Time: Infants at 12 months needed only 10 seconds to encode a shape, whilst at 6 months infants need at least 20 seconds.
Stimulus Complexity: It takes longer for infants to encode a shape if it is more complex, also younger infants cannot encode complex shapes until 4 months, and get better by 5-6 months.
