What is the importance of assessing reflexes?

, eye blink, rooting, sucking, swimming, Moro, palmer grasp, tonic neck, stepping, Babinski) ∙ When and why do some of these initial reflexes disappear?

Chapter 3 Terms: ∙ Conception ∙ Zygote ∙ Blastocyst ∙ Implantation ∙ Placenta ∙ Umbilical cord ∙ Embryo ∙ Neural tube—brain ∙ Fetus  ∙ Age of viability  Key Points:  ∙ The 3 periods of prenatal development (If you want to learn more check out What does explicit cost refer to?

If you want to learn more check out What do muscle forces do?
If you want to learn more check out What are the differences among emotion, affect, and mood?
We also discuss several other topics like The Dark Knight was released in what year?

zygote, embryo, fetus); associated  time frame and main events that take place during these periods ∙ Brain development during prenatal development  ∙ Prenatal environmental influences terms: ∙ Teratogens ∙ Sensitive period ∙ Fetal alcohol syndrome (FAS) ∙ Fetal alcohol spectrum disorder (FASD) ∙ Partial alcohol Syndrome (p-FAS) ∙ Alcohol-related neurodevelopmental disorder (ARND) Key points: ∙ Four factors that affect the nature and extent of harm associated with any  given teratogen ∙ Explain the importance of the concept of “Sensitive Period” during prenatal  development  ∙ Facts related to common teratogens and prenatal development, I.e., drugs,  tobacco, alcohol, radiation, environmental pollution, and maternal disease.  Childbirth key terms: ∙ Apgar scale ∙ Preterm vs. small-for-date infants  Key points:  ∙ What risks are associated with oxygen deprivation and with preterm and low birth-weight infants Key Terms ∙ Heredity, environment & behavior: a look ahead terms:∙ Behavioral genetics  ∙ Concordance rates ∙ Heritability estimates ∙ Canalization ∙ Genetic-environmental correlation o Passive correlation  o Evocative correlation o Active correlation   Niche-picking ∙ Epigenetic framework Key Points: ∙ Identify and describe the measures/indexes used to infer the contributions of  heredity to human characteristics, i.e., heritability estimates; concordance  rates ∙ Describe how nature and nurture work together; i.e., canalization and  genetic-environmental correlation  ∙ Identify and describe three types of genetic-environmental correlations. Give  an example of each. ∙ Explain the epigenetic framework  Chapter Four:  The organized Newborn: reflex and states of arousal terms: ∙ Reflex ∙ States of arousal ∙ REM sleep ∙ NonREM sleep ∙ Sudden infant death syndrome ∙ Neonatal behavioral assessment  People to know: ∙ T. Berry Brazelton Key points: ∙ Describe the believed functions of a newborn’s reflexes ∙ Identify and describe various newborn reflexes (i.e., eye blink, rooting,  sucking, swimming, Moro, palmer grasp, tonic neck, stepping, Babinski) ∙ When and why do some of these initial reflexes disappear? What is the  importance of assessing reflexes? ∙ Identify and describe infant’s states of arousal. ∙ Describe the sleep pattern of infants, and explain how it Is similar or different  to that of older children and adults. What is the believed function of REM  sleep in infancy? ∙ Why do babies cry?∙ Describe the use of the neonatal behavioral assessment  The organized newborn: learning capacities Terms: ∙ Learning ∙ Classical conditioning o Unconditioned stimulus (UCS) o Unconditioned response (UCR) o Conditioned stimulus (CS) o Conditioned response (CR) ∙ Extinction  ∙ Operant conditioning  o Reinforce o Punishment  ∙ Habituation o Recovery o Novelty preference o Familiarity preference  o Recent? Memory  o Remote? Memory  ∙ Imitation  Key Points: ∙ Identify and describe infant learning capabilities. Discuss the conditions  under which they occur, and be able to cite and explain various applied  examples of infant learning. Specifically, describe how learning takes place  through: o Classical conditioning  o Operant conditioning o Habituation o Imitation  Motor Development in Infancy: Terms:  ∙ Gross motor development ∙ Fine motor development  ∙ Cephalocaudal trend ∙ Proximodistal trend  ∙ Dynamic systems theory of motor development  ∙ Pre-reaching ∙ Ulner grasp  ∙ Pincer grasp  Key Points:∙ Describe how the development of motor skills support the development of  other domains, e.g., social and emotional development  ∙ Define gross motor development and fine motor development. Give examples of each ∙ Describe the general trend in motor skill development (i.e., cephalocaudal  and proximodistal tends) ∙ Describe the dynamic systems theory of motor development.
