- The parents’ and society’s responsibility to mold the child to fit
- Nearly a century after Locke, Jean-Jaques Rousseau proposed…
- He conveyed his thoughts on child raising how?
- that society was not only unneccessary, but a detriment to optimal development.
- in a book called “Emile: Concerning Education”. The book is a comprehensive guide to pedagogy (the method and practice of teaching). The book was so controversial that he had to flee France to avoid arrest

- He published “Psychology as the Behaviourist Views it” in the journal called “Psychological Review”, which criticized the field of psych as being too focused on mentalistic concepts.
- He accepted Locke’s view of the tabula rasa and believed in the environmental influences on child development
- “Give me a dozen healthy infants, well-formed, and my own special world to bring them up in and I’ll garuntee i’ll take any one at random and train him to become any type of specialist i might select - doctor, lawyer..-regardless of his talents, penchants, tendencies, abilities and vocation and race of his ancestors”
- John Watson’s theory placed a great deal of responsibility on who for raising competent children? And how did he suggest this?
- Watson also believed that __ and __ were acquired through learning.
- parents; by providing the right learning experiences, and doing so while avoiding overt “sentimental” affection
- emotion and thought
- Watson believed which methods were useful in the study of psychology/
- He believed psychology should never discuss…
- As an early behaviourist, Watson believed that the goal of psychology should be…

- What are the 3 research methods typically used in developmental psychology?
- What is one possible additional method?
- Cross-sectional, longitudinal, sequential cohort studies (combo of cross sectional and longitudinal where several group of different ages are studied over several years)
- Case study/clinical method where they attempt to collate facts about a particular child
- The study of genetics was initiated by __ __
- What is the huge thing he is known for and how did he figure it out?
- He suggested that each specific trait was controlled by an…, and that each variation was represented by…
- Gregor Mendel, an Austrian monk who lived in the 19th century
- By carefully observing the inheritance of certain traits in pea plants, he hypothesized the existence of the basic unit of heredity, the GENE
- an alternative form of a gene called an ALLELE; an allele that was either DOMINANT or RECESSIVE
- For any given gene, there are 2 __
alleles
- In humans, both parents contribute a __ for each __
- The dominant allele will be expressed in which situation(s)?
- The recessive allele will be expressed in which situation(s)?
- gene; trait
- 1) both parents contribute dominant allele, 2) one contributes dom and the other recessive
- 1) both parents contribute a recessive allele
- Genotype =
- the total genetic makeup of an individual
Phenotype =
The collection of expressed traits that constitute the individual’s observable characteristics
People with identical __ can have different __
- phenotypes; genotypes
What a chromosomes made of?
- DNA strands and proteins
Humans have _ chromosomes, organized into _ homologous pairs, of which _ are autosomes
-46, 23, 22
What determines the sex of the child?
The 23rd pair of chromosomes
The human body, except for sperm cells and egg cells, holds..
- all 23 pairs of chromosomes
- What is diploid?
- Which cells in the human body are diploid?
- Somatic cells in the human body are diploid
- It means that the chromosomes they contain exist in pairs
- What is haploid?
- Which cells in the human body are halpoid?
- It means they contain 23 single chromosomes
- The gamates (sperm and egg cells) are haploid
- Why is the arrangement of haploid and diploid cells necessary?
- Because when the sperm and egg cells join together for conception, the two hapoid cells come together to make a full complement diploid of 23 chromosome pairs. In this way, each parents contributes one gene for each trait.
- Why is normal human genetic variability greater than in asexual reproduction?
- Because the offspring of sexual reproduction receives genes from both parents
- Children can be said to have an average of _% of their genes in common with each parent.
- Siblings share what percent?

- 50%
-50%
100%
- In addition to characteristics such as sex and eye colour, genes are also thought to effect behaviour. R.C Tyron’s studies on the…. are one of the clearest examples.
- Describe his study
- What did further studies reveal about specific maze types?
- inheritance of maze-running abilities
- Page 72- selectively bred “maze bright” and “maze dull” rats and found that, after generations of breeding, the difference between the two rats intensified, providing evidence that learning ability had a genetic component.
- That performance between the two groups on maze types that were different from what the “maze bright” rats were trained on was no different between groups
- Research that determines the degree of genetic influence on individual differences between people uses one of 3 methods:
- family studies, twin studies, adoption studies

- cognitive, social, emotional
- Researchers have found that MZ twins are treated more…
- MZ twins also tend to __ __ more then DZ
- To better measure genetic effects relative to environmental effects, researchers compared personality characteristics in twins who were raised together (same family) to twins raised apart (different families). On personality measures, MZ twins raised in same fam are more similar. MZ twins raised in the same fam are __ similar in personality characteristics than DZ twins raised apart.
- DZ twins raised apart are the __ similar.
- What does the research in this slide suggest about personality traits?
- similarly than DZ twins
- imitate each other
- more
- least
- that they are at least somewhat heritable
- What has research found about IQ between adoptive and bio parents?
- IQ is more similar to bio parents, suggesting that IQ is heritable. Criminal behaviour among boys shows a similar pattern of heritability
- Lewis Terman’s study compared….
- This study was important because..
- a group of children with high IQs (135 and above) with groups of children typical of the general population to discover similarities and differences.
- it was the first to focus on “gifted children”, and because it was a large-scale longitudinal study that followed the development of the group over time, observing them every 5 years

- a failure to develop secondary sex characteristics, physical abnormalities such as short fingers and unusually shaped mouths
- Conception takes place in the…
- fallopian tubes
- Describe the stages of prenatal development:
1) Zygote: The sperm cell fertilizes the egg cell and forms a single cell (zygote)
2) Germinal period: Fertilized egg travels down the fallopian tube and is implanted into uterine wall

- nutrients to the fetus while also returning waste laden blood to the mother
_ proteins, amino acids
- A variety of external influences can have deleterious effects on the development of the fetus. Infants whose mothers contract __ or __ __ before the end of the _ __ run a high risk of…
- What happened with thalidomide?
- rubella, german measles; cataracts, deafness, heart defects and intellectual disability. Other viral infections (measles, mumps, hep, flu, chicken pox, herpes, etc, also linked to various birth defects)
- this is a tranquilizer that was prescribed to women in the 1950s. Mother who took this drug while pregnant often gave birth to babies with missing and malformed limbs and defects of the heart, eyes, digestive tract, ears and kidneys.
- __ __ is considered to be the leading cause of abnormal development
- page 76 for several things that effect fetus
- maternal malnutrition
- Name and describe the 4 neonatal reflexes
1) Rooting - infants automatically turn their heads in the direction of stimuli applied to the cheek (e.g., nipple during feeding)
* *Sucking and swallowing when an object is placed i the mouth are also examples of reflexes related to the feeding situation.
2) Moro - infants reactions to abrupt movements of their heads by flinging out their arms, extending their fingers, bringing their arms back to their body essentially hugging themselves
3) Babinski - infant’s toes automatically spread apart when the soles for feet stimulated
4) Grasping - infants automatically close their fingers around objects placed in their hands
