Chapter 14 Flashcards
Development
Refers to the physiological, behavioural, cognitive and social changes that occur throughout the human life
Infancy
Development stage that begins at birth and continues to one year of age
Childhood
The period between infancy and the onset of puberty
Adolescence
Years between the inset of puberty and the beginning of adulthood
What was Robert Klark Graham right about
Nature plays a substantial part of development
Conception
When an egg is fertilized by sperm
Ovulation
When an egg which has ben stored in the mothers ovaries, matures and is released into the fallopian tube
Zygote
A ferilized egg
Embryo
Once the zygote attaches to the wall of the uterus, it is known as embryo
Embryonic Stage
Lasts for 6 weeks. Major internal and external organs formed
Aminotic Sac
Fluid filled reservoir in which the embryo will live until birth
Placenta
Organ that allows the exchange of nutrients between the embryo and the mother.
Umbilical cord
Links the embryo directly to the placenta and transfers all material to the fetus
Fetus
Beginning of the 9th week of conception, embryo becomes a fetus
Teratogens
Substances that can harm the fetus
Fetal Alcohol Syndrome
Condition caused by maternal alcohol drinking that can lead ti numerous development effects, including limb and facial abnormalities, genital abnormalities and intellectual disability
Rooting Reflex
Stimuli: Baby cheek is stroked
Response: Baby turns its head toward the stroking, open its mouth and tires to suck
Significance: Ensures the infants feeding will be a reflexive habit
Blink Reflex
Stimulus: A light is flashed in the baby eyes
Response: The baby closes both eyes
Significance: Protects eyes from strong and potentially dangerous stimuli
Withdrawl Reflex
Stimulus: A soft pinprick is applied to the sole of the babys foot
Response: The baby reflexes the leg
Significance: Keeping the exploring infant away from painful stimuli
Tonic Neck Reflex
Stimulus: Baby is laid down on its back
Response: Baby turns on its head to one side and extends the arm on the same side
Significance: Helps develop hand eye coordination
Grasp Reflex
Stimulus: An object is pressed into the palm of the body.
Response: The baby grasps the object pressed and can even hold its own weight for a brief period
Significance: Helps in exploratory learning
Moro Reflex
Stimulus: Loud noises or a sudden drop in height while holding the baby.
Response: The baby extends arms and legs and quickly brings them in as if trying to grasp something.
Significance: Protects from falling; could have assisted infants in holding on to their mothers during rough travelling
Stepping Reflex
Stimulus: The baby is suspended with bare feet just above a surface and is moved forward
Response: Baby makes stepping motions and as if trying to walk
Significance: Helps encourage motor development
Habitutation
Decreased responsiveness towards a stimulus after it has been presented numerous times in succession
Schemas
Patterns of knowledge in long term memory
Assimilation
Use already developed schemas to understand new information
Accommodation
Learning new information and thus changing the schema
Piagets Stages of Cognitive Development
Sensorimotor, Preoperational, concrete operational and Formal Operational
Sensorimotor
Birth to about 2 years: The child experiences the world through the fundamental senses of seeing, hearing, touching and tasting
Preopreational
2 to 7 years: Children acquire the ability to internally represent the world through language and mental imagery. They also start to see the world from others perspectives. Begin to use language and to think More abstractly about objects.
Concrete Operational
7 to 11 years: Children become able to think logically. They can increasingly perform operations on objects that are only imagined
Formal Operational
11 years to adulthood: Adolescents can think systematically, can reason about abstract concepts and can understand ethics and scientific reasoning
Self concept
Knowledge representation or schema that contains knowledge about us
Secure Base
Allows them to feel safe
Strange Situation
Meaure of attachment in young children in which the Childs behaviours are assessed in a situation in which the caregiver and a stranger move in and out of the environment
