Exam 2 Flashcards
Moro reflex
a startle reaction to loud noises in which infants fling their arms out and then draw then in, arch their backs, and extend their legs. trying to grab something to protect self, potentially like falling. disappears around 5 to 6 months
Babinski reflex
infant spreads out and curls toes, turns foot inward. changes at 12 months
Tonic neck
infant turns head to one side, arm on that side of the body extends, other arm is bent. disappears around 3 to 4 months
Cephalocaudal
from the head downward. infants can raise their head before they stand up
Sensorimotor substage 1
birth-1 month. Simple reflexes essential tools for intelligence. Infants accommodate reflexes to fit environment. (they practice reflex actions)
Sensorimotor substage 2
1-4 months. Infants organize separate reflexes into more complex behaviors → primary circular reactions (repetitive actions centered on the infant’s body)
Sensorimotor substage 3
4-8 months. Primary circular reactions combine into more coordinated patterns->grasping objects. Secondary circular reactions (repetitive actions centered on qualities of objects such as noise, shapes, colors). Infant uses visually guided reaching for greater exploration
Sensorimotor substage 4
8-12 months. Coordination of secondary circular reactions. Object Permanence. Fragility of infant’s mental representations of objects seen in A-Not-B Error (infant’s tendency to search in the first hiding spot (A) while ignoring the second (B).). Shows first signs of intelligence by using intentional behavior to solve problems.
Sensorimotor substage 5
12-18 months. Being to apply new strategies to solve problems. Tertiary circular reactions → infants modify behavior with objects in subtle ways (modified repetitive actions designed to explore qualities of objects)
Sensorimotor substage 6
18-24 months. Infants begin to be able to form enduring mental representations. Deferred Imitation: repetition of other’s behaviors minutes, hours, or days after it occurred (shows memory, babies can do it for longer periods of time increasingly). Achieves greater flexibility in problem solving by using symbols to represent objects.
Secondary circular reaction
action gets a response from another person or object, leading to repetition of original action. 4-8 months (substage 3). repetitive actions focused on the qualities of objects, such as the noises they make or their shapes and colors.
Recall memory
active retrieval of information from memory
Cued recall
memory in which a familiar stimulus triggers recall of stored information
Recognition memory
a particular stimulus is perceived as familiar
Explicit memory
develops after 6 months. depend on cerebral cortex and its connections with the hippocampus. is conscious, involves mental representation of images or ideas, can be explicitly stated or declared. ex: the first time I rode a bike instead of how to
Implicit memory
first 6 months. depend on cerebellum and hippocampus. is unconscious, involves memory for PROCEDURES or skills, does not lend itself to explicit statement. ex: how to ride a bike
Infantile amnesia
Inability to recall events that occurred very early in life. don’t have great language associated with earliest memories which makes it difficult later on to describe it
Deferred imitation
repetition of other’s behaviors minutes, hours, or days after it occurred (shows memory, babies can do it for longer periods of time increasingly)
Phoneme
Basic sounds of language (e.g., /sh/ sound not the same as /s/)
Receptive language (Wernicke’s area)
Children’s understanding of language. Precedes their ability to produce (e.g., Before they can verbally respond to “where is the dog?” they look toward the dog.)
Expressive language (Broca’s area)
Children’s ability to produce language. Real words not until about 12 months. Important b/c now they understand the symbolic importance of the words. Usually objects in social world or people (Social context facilitates language development; May use holophrases: individual words that convey as much meaning as whole sentences e.g., “Doggie” can mean the dog entered the room or I want to play with dog.)
Telegraphic speech
Early language in which only highly informative words are used and less informative words are neglected (e.g., “doggie soft”)
Overregularization
Language errors in which a child applies a morphological rule to a word that is an exception to the rule (ex: “mouses” for mice)
Child directed speech/Infant directed talk/Parentese
Special style of speech used with infants and young children. Simple repetitive sentences (simple vocabulary) spoken in attention getting ways. (ex: Emotion tone (affection); Exaggeration (high tone, extreme changes in intonation); Slow & clear; Elongated pauses between utterances; Accompanied by exaggerated facial expressions). CDS enhances language skills in children.
Mothers who take turns with children learn language more rapidly.
Stranger distress
negative reactions of infants to strangers. A stranger staring can cause a 5-month-old infant to cry after about 30 seconds. At 7-10 months, babies begin to react negatively to strangers even without prolonged stares. This stranger distress usually continues for 2-3 months. Degree of stranger distress varies greatly from baby to baby.
Emotion regulation
ability to alter emotional responses to a situation. Capacity to cope with emotionally arousing situations begins to develop in first 6 months. Early techniques of ER are global and involuntary and interrupt contact with the environment.
Social smile
By 10 weeks of age, the infant uses the smile for instrumental purposes (to get something or to reinforce for a behavior that is appealing). Babies are more likely to smile to their mother when the mother is attentive to the child (smile is responsive to the social context). Promotes close ties and social connection with caregivers (adaptive).
Development of Emotions
Newborns’ physiological responses to stimulation develop into forerunners of specific basic emotions, but differ from these emotions in several ways:
They often require time to build up.
Meanings attached to events involved are very general.
They are not well differentiated.
Basic cry
Rhythmic pattern of crying with brief silence, short inhalation whistle and brief silence
Anger cry
Excess air forced through vocal cord, gives more breathy cry
Pain cry
Sudden & loud onset & duration, breath holding
Hunger cry
Similar to basic cry, tends to be rhythmic & kicking in same rhythm as cry
