Q

4 Stages of Cognitive Development

A
  1. Sensorimotor
  2. Preoperational
    During early childhood 2-5 years old
    Pretend imaginative thinking, capacity for symbolic thought (language)
  3. Concrete operational
    In middle childhood, understanding concepts well when they are physically present (like learning addition)
  4. Formal operational
    Adolescents, abstract thinking in figurative language (literature and writing), and algebraic expressions. Outside social events and peers present hypothetical thinking as well.

Q

Sensorimotor Stage

A

1st stage of cognitive development, which leads through infancy and is generally characterized by an increasingly complex coordination of sensory experiences with motor activity.

First two years of cognitive development
(a time when infants progress from responding to events with reflexes, or ready-made schemes, to goal-oriented behavior)

Q

Mirror Neurons

A

They are activated when the individual performs a motor act or observes another individual engaging in the same act.

  • Connected with emotions (frontal lobe)
    *Active when people experience disgust, happiness, pain, and when they observe another experiencing an emotion
  • Also with the instinctive human ability to acquire language

Q

Bayley Scales of Infant Development
(intellectual Development among Infants)

A
  • Mental Scale - assesses verbal communication, perceptual skills, learning and memory, and problem-solving skills
  • Motor Scale - Assesses gross motor skills, such as the ability to manipulate the hands and fingers
  • Behavior Rating Scale - Based on examiner observation of the child during the test. Assesses attention span, goal-directedness, persistence, and aspects of social and emotional development.

* It Remains unclear how well results obtained in infancy predict intellectual functioning at later ages*

Q

Truth or Fiction
Psychologists can begin to measure intelligence in infancy

A

True
They use items that differ from the kinds of items used with older children and adults

There is always controversy about what researchers are actually measuring when they set out to measure “intelligence.”

Q

Visual Recognition Memory

A

Kind of memory shown in an infant’s ability to discriminate previously seen objects from novel objects (based on habituation)

*Increase over the first year after birth

  • Test of visual recognition hold better promises as predictors of intelligence at older ages.

Q

Truth or Fiction
Infant crying is a primitive form of language

A

Fiction
In true language, words are symbols for objects or events. Cries may express discomfort, but they are not symbols.

25
Cooing
Prelinguistic vowel-like sounds reflect feelings of positive excitement (During 2nd month) *Early parent-child "conversations," in which parents respond to coos and then pause as the infant coos, may foster infant awareness of taking turns as a way of verbally relating to other people*
26
Babbling
The child's first vocalizations that have sounds of speech *Frequently combining consonants and vowels, as in a ba, ga, and sometimes dada*
27
Echolalia
The automatic repetition of sounds or words
28
Intonation
The use of pitches of varying levels to help communicate meaning * Use patterns of rising and falling that resemble sounds of adult speech*
29
Development of Vocabulary
Refers to a child's learning the meanings of words.
30
Receptive Vocabulary
The number of words one understands
31
Expressive Vocabulary
The number of words one can use in the production of language *Children's receptive vocabulary development outpaces their expressive vocabulary*
32
A good predictor of infants' vocabulary at 24 months
The ability to segment speech sounds into meaningful units-or-words before 12 months
33
Child's first word
Typically between the ages of 11 and 13 months *But a range of 8 to 18 months is considered normal.* a. brief short, one or two syllables b. consistent of a consonant followed by a vowel c. may take 3 or 4 months to achieve vocabulary of 10 to 30 words after first word
34
Children may be producing up to 50 words
By about 18 months * Many are familiar words like no, cookie, mama, hi, and eat. * Others are functional words like all gone and bye-bye (they are used consistently to symbolize the same meaning*
35
General and Specific Nominals
More than half (65%) of children first words
36
General Nominals
Similar to nouns, including to names of objects (car, ball), animals (doggy, cat), and people (boy, girl), but also include both personal and relative pronouns (she, that)
37
Specific Nominals
Proper nouns such as Daddy and Rover
38
Rapid Burst in Vocabulary
At about 18 to 22 months *May increase from 50 to more than 300 words in only a few months *vocabulary spurt could also be a naming explosion due to 75% of the words added during this time are nouns*
39
Overextensions
Use of words in situations in which their meanings become extended
40
Development of Sentences
Infants' first sentences are typically one-word utterances, but they express complete ideas and, therefore can thought of as sentences
41
Telegraphic Speech
Type of speech in which only the essential words are used. (Such as nouns, verbs, and some modifiers)
42
Mean Length of Utterance (MLU)
The average number of morphemes used in an utterance
43
Morphemes
The smallest unit of meaning in a language *Maybe a whole word or part of a word, such as a prefix or suffix* Example: Word "walked" consists of two morphemes: the verb "walk" and the suffix "ed," which changes the verb to the past tense.
44
Two types of Telegraphic Speech
*Holophrase *Two-word Utterances
45
Holophrase
A single word that is used to express complex meanings *the child may use Mama to signify meanings as varied as "There goes Mama", "Come Here, Mama", and "You are Mama." *
46
Two-word Utterances
When the child's vocabulary consists of 50 to 100 words * Somewhere between 18 to 24 months, telegraphic two-word sentences begin to appear* In the sentence "That Ball" the word 'is' and 'a' are implied
47
Syntax
The rules in a language for placing words in order to form sentences
48
Models
In learning theory, those whose behaviors are imitated by others *children learn by observation and imitation*
49
Extinction
Decrease in frequency of response due to absence of reinforcement
50
Shaping
The gradual building of complex behavior through reinforcement of successive approximations to the target behavior *Parents require that children's utterances be progressively closer to actual words before they are reinforced * Reinforcement can accelerate the growth of vocabulary in children
51
Studies show that language growth in young children is enhanced when adults
* Use "motherse" (infant-directed) * Use questions that engage the child in conversation * Respond to the child's expressive language efforts in a way that is "attuned." Example: Say "Yes, your doll is pretty" in response to the child's statement "My doll" * Gesture to help the child understand what they are saying * Describe aspects of the environment occupying the infant's current focus of attention * Read to the child * Talk to the child a great deal
52
Truth or Fiction You can advance children's development of pronunciation by correcting their errors.
Fiction Their vocabulary may not develop as rapidly if you focus on pronunciation.
53
Psychological Theory
The view is that language learning involves an interaction between environmental influences and an inborn tendency to acquire language.
54
Language Acquisition Device (LAD)
Neural "prewiring" eases the child's learning of grammar.
55
Surface Structure
The superficial grammatical construction of a sentence
56
Deep Structure
The underlying meaning of a sentence
57
Brain Structures involved in Language
The basis for functions of the LAD is based in the Left Hemisphere of the cerebral cortex for nearly all right-handed people and 2 out of 3 left-handed people.
58
Two areas most involved in Speech
*Broca's Area * Wernicke's Area
59
Aphasia
Disruption in the ability to understand or produce language (damage to either area)
60
Broca's Area
Located near the section of the motor cortex that controls the muscles of the tongue and throat and other areas at the face used for speech.
61
Broca's Aphasia
An aphasia caused by damage to Broca's area and characterized by difficulty speaking (But can understand speech)
62
Wernicke's area
It lies near the auditory cortex and is connected to Broca's area by nerves
63
Wernicke's Aphasia
An aphasia caused by damage to Weinicke's area and characterized by impaired comprehension of speech and difficulty producing the right word
64
Angular Gyrus
Lies between the visual cortex and Wernicke's area, translates visual information, such as written words, into auditory information (sounds), and sends it to Wernicke's area. Problems in this area can cause problems in reading because it is difficult for the reader to segment words into sounds
65
Critical Period
The period from about 18 months to puberty when the brain is especially capable of learning language AKA: Sensitive Period
