Q

Define Case Study

A

The in-depth study of a single individual or a single institution, agency, community, or other social unit. Case studies do not permit conclusions about the nature of the relationship between variables and may not be generalizable to other cases. It is often used to identify variables for future research.

Q

Cohort Effects

A

Differences between subjects of cross-sectional research that have to do with experience rather than with age. Cohort effects can suggest that observed differences between different aged subjects are related to their different experiences in life instead of the differences in age.

A

Forming of a close emotional and physical connection between child and parents, especailly right after birth.

28
Q

A

Physical and mental abnormalities (e.g., Mental Retardation, micorcephaly, hyperactivity, cardiac defects) caused by excessive maternal alcohol intake during pregnancy.

29
Q

Neuron

A

A nerve cell which consists of dendrites, soma (cell body), and axon. It receives input from and transmits impulses to other cells in the body and is the basic building block of the nervous system.

30
Q

Placenta

A

A conduit between the mother and fetus which provides the fetus oxygen and nourishment via the umbilical cord.

31
Q

Teratogen

A

Any biological (e.g., German measles) or chemical (e.g., various drugs) agent which can reach and harm the developing embryo or fetus.

32
Q

Dishabituation

A

Recovery of a habituated response after a change in stimuation

33
Q

Grasping Reflex

A

Neonatal reflex in which the infant grasps tightly when the palm of the hand is touched

34
Q

Habituation

A

Process of becoming accustomed (nonreactive) to a stimulus as the result of prolonged exposure to it..

35
Q

Intermodal Perception

A

Ability to relate and integrate data from different sensory sources, such as vision and hearing.

36
Q

Lateralization of Function

A

Tendency for each hemisphere to dominate over the other for specific functions. Also refers to the relationship between handedness and cerebral hemisphere dominance for functions. Nearly all right handers and more than half of all left handers have left hemisphere dominance for language and right hemisphere dominance for spatial skills..

37
Q

Moro reflex

A

Neonatal reflex in which the infant - when startled - will arch its back, throw its head back, and fling out its arms and legs. Then the infant will close its arms and legs to the center of the body

38
Q

Perception

A

The process of organizing and interpreting sensory information to make it meaningful to the person.

39
Q

Reflex

A

A simple and unlearned response to sensory stimulus, such as cringing when hearing a loud noise or the knee-jerk response

40
Q

Rooting Reflex

A

Neonatal reflex in which the infant - when its cheek is stroked - will turn its head toward the side which was stroked in an apparent effort to find something to suck.

41
Q

Sensation

A

The process of how sensory organs are stimulated to produce neural impulses that the brain can interpret.

42
Q

Shape Constancy

A

The awareness that the shape of an object remains the same even though we might see it from different angles.

43
Q

Size Constancy

A

The awareness that the size of an object remains the same even though we see it from different distances

44
Q

Sucking Reflex

A

Neonatal reflex in which the infant will automatically suck an object placed in its mouth. The enables the infant to get nourishment and also can be as a self-soothing or self-regulating mechanism.

45
Q

Accommodation

A

According to Piaget’s theory of cognitive development, changes made to existing cognitive structures or schemes in order to understand and incorporate new information and experiences.

46
Q

A-not-B error (also AB error)

A

Error that happens when infants select a familiar/previous hiding place (A) rather than a new hiding place (B) they have just been shown.

47
Q

Assimilation

A

According to Piaget’s theory of cognitive development, the process of incorporating new objects, information, or experiences into the existing cognitive structures or schemes.

48
Q

Attention

A

Focusing conscious thought onto a single concept or source of information.

49
Q

Broca’s Area

A

Motor speech area in the brain associated with the production and articulation of speech. Damage results in expressive aphasia..

50
Q

Child-Directed Speech (also motherese and babytalk)

A

Speaking to a child using simplified vocabulary, sentence structure, in a higher pitch, and with more inflection. This appears to actually help the child learn a language more efficiently.

51
Q

Equilibration

A

The process Piaget proposed that explained how children shift from one stage of thought to the next.

52
Q

Explicit Memory

A

Memory of facts and experiences consciously known.

Q

Infinite Generativity

A

Idea that a person can produce an endless number of meaningful sentences using a finite set of words and rules.

55
Q

Language

A

Systematic and meaningful arrangement of symbols (spoken, written, of signed) which provides a basis for communication.

56
Q

Morphology

A

Studying the units of meaning (morphemes) attached to different sounds in a speech community. For example, the use of “s” to indicate plurality is an example of a morpheme.

57
Q

Object Permanence (Object Concept)

A

term used by Piaget to describe a child’s realization that an object continues to exist even though it is not in view. Develops during the sensorimotor stage..

58
Q

Phonology

A

The sound system of a given speech community which includes what types of sounds are used and how they may be combined.

59
Q

Pragmatics

A

The rules used in speech community which govern how to communicate effectively and appropriately in different contexts.

60
Q

Schemes

A

In Piaget’s theory, actions or mental representations that organize knowledge. These adapt and change as the child develops mentally.

61
Q

Semantics

A

The branch of linguistics focusing on the study of meaning, changes in meaning, and the principles that govern the relationship between sentences or words and their meanings

62
Q

Sensorimotor stage

A

The first stage in Piaget’s theory (birth - 2 yrs old) in which the children know the world primarily through their sensory impressions and motor activities.

63
Q

Syntax (Grammar)

A

The conventions a speech community uses to govern how words are combined to form acceptable phrases and sentences.

64
Q

Telegraphic Speech

A

Speech in which words not critical to the message are left out

65
Q

Wernicke’s area

A

Speech area located in the temporal lobe (usually left lobe). Responsible for the understanding of written and spoken language. Lesions produce receptive aphasia.
