Heritability Estimate; Phenotype; Genotype
____ refers to a person’s genetic inheritance, while ____ refers to their observed characteristics, which are due to a combination of heredity and environment. As an example, a person whose parents are both very tall maybe genetically predisposed to be taller-than-average but end up shorter than his genetic makeup dictates due to illness or poor diet.

Bronfenbrenner Ecological Model; Bronfenbrenner; Individual; Context or Environment; Ecological Model
The ____ is the child’s immediate environment and includes face to face relationships with the home, school, and neighborhood. The mesosystems refer to interactions between components of the micro system, such as the influence of family factors on the child behavior at school.
Microsystem
The ____ refers to interactions between components of the microsystem, such as the influence of family factors on the child’s behavior at school.
Mesosystem
The ____ consists of elements in the broader environment that affect the child’s immediate environment and includes the parents’ workplace, the school board, community agencies, local industry, and the mass media.
Exosystem
The ____ is comprised of such overreaching environmental influences as cultural beliefs and practices, economic conditions, and political ideologies.
Macrosystem
The ____ system consists of environmental events that occur over and individual’s lifespan and impact the individual in ways that depend on their circumstances and developmental stage, such as the immediate and long-term effects of change and family structure or socio-economic status.
Chronosystem
____ and ____: the long-term impact of environmental factors that place infants and young children at high risk has been explored by several investigators. Rutter (1985) proposed that the greater the number of risk factors a baby is exposed to, the greater the risk for ____ ____.
Risk and Resilience; Negative Outcomes
In one study Rutter found that psychiatric risk for children increased from _% for those with ____ or ____ risk factors to _% for those with four or more risk factors. Rudder concluded that the following six family characteristics known as ____ ____, are particularly accurate predictors of child psychopathology.
2%; One or No; 21%; Four More Risk Factors; Rutter’s Indicators
Rutter’s Indicators
- severe marital discord, low socioeconomic status, overcrowding or large family size, parental criminality, maternal psychopathology, and placement of the child outside of the home.
In their longitudinal city of high-risk infants on the island of Kauai, Warner and her colleagues found that, while infants who experience significant prenatal and perinatal stress had more ____ and ____ ____ than infants who did not, the differences between two groups of infants ____ ____.
Physical and Cognitive Difficulties; Declined Overtime
Positive outcomes for high-risk babies were more likely when they experienced fewer ____ ____ ____ such as more negative effects were associated with chronic poverty, family instability, and maternal health problems; he had an ____ ____ marked by a high degree of social responsivity, good communication skills, and consistent eating and sleeping patterns; see we’re provided with ____ ___ from a parent or other caregiver. Such findings were important because they suggest that high risk children demonstrate ____ ____ and that the negative effects of parental and perinatal stress are not always ____.
Stressors Following Birth; Easy Temperament; Stable Support; Considerable Resilience; Irreversible
____-____ ____: Several explanations of how genetic and environmental factors combine to produce an individual’s attributes have been proposed.
Heredity-Environment Interactions
____ ____: Some experts contend that there is a ____ of ____ for certain traits and that an individual’s status within that range depends on environmental factors. For instance, as previously noted, a person may be shorter than his or her genetic predisposition dictates due to illness or poor diet. According to this explanation, genetic make-up determines whether the reaction range is ____ or ____.
Reaction Range; Range of Reaction; Narrow or Broad
A child born with a defect that produces mild cognitive impairment will have a ____ ____ ____ than a child born with a defect that causes severe impairment and will, therefore, have a g-eater response to an enriched environment. Note that the term “____” is used to describe characteristics in which genotype restricts phenotype to a small number of possible outcomes.
Broader Reaction Range; Canalization
____-____ ____: This explanation proposes that a person’s genetic make-up influences the environments the person is exposed to and that exposure to those environments reinforces the person’s genetic make-up. There are three types of genotype-environment correlation.
Genotype-Environment Correlation
Occurs when children inherit genes from their parents that predispose them toward particular traits, and the parents provide the children with environments that encourage the development of those traits. For instance, the children of athletic parents are likely to be genetically predisposed to athleticism and will also be provided by their parents with a sports-oriented environment that encourages their interest and participation in sports.
Passive genotype-environment correlation
Occurs when a child’s genetic make-up evokes reactions from parents and others that reinforce his or her genetic make-up. As an example, preschool children who are genetically predisposed to be cooperative and attentive will have more positive instructional interactions with teachers than will uncooperative, inattentive children.
Evocative genotype-environment correlation
____ ____-____ ____correlation is also referred to as ____-____. It occurs when children actively seek out experiences that are consistent with their genetic predispositions. Children who are extroverted, for instance, will seek out socially stimulating activities, while children who are introverted will actively avoid those activities.
Active Genotype-Environment Correlation; Niche-Picking
According to Scarr and McCartney, the relative importance of the three types of genotype-environment correlation ____ ____ ____: The importance of the passive and evocative types is greatest during ____ and ____ ____ when children have little control over their environments, while the active type becomes increasingly important as children become ____ ____.
Changes Over Time; Infancy and Early Childhood; More Independent
____: The epigenetic explanation describes the relationship between genetic and environmental influences as bidirectional and ongoing. From this perspective, each stage of development is affected by ____ ____, ____, ____, and ____ ____ and, in turn, affects ____ ____.
Epigenesis; Previous Genetic, Neural, Behavioral, and Environmental Interactions; Future Interactions
During prenatal development, malnutrition or exposure to certain toxins may influence the functioning of genes that control temperament, and the child’s temperament then affect his parents’ behaviors which, in turn, will affect the child’s attachment style and other characteristics, and so on.
An example of Epigenesis
Several theories of lifespan development have been influenced by ____ and ____ ____, which have their historical roots in ____ ____ of ____ ____.
Ethology and Evolutionary Psychology; Darwin’s Theory of Natural Selection
____ is the branch of the zoology that is dedicated to the study of animal behavior in natural habitats. ____ ____ are based on the assumptions that “all animal species are born with a number of ‘biologically programmed’ behaviors that are (I) products of ____ and (2) are ____ in that they contribute to ____.”
Ethology; Ethological Theories; Evolution; Adaptive; Survival
The influence of ethology is illustrated by the interest of developmental psychologists in ____ ____, which are specific, predetermined periods of time during biological maturation when an organism is particularly sensitive to certain stimuli that can have either a positive or negative impact on development.
Critical Periods
The zoologist Konrad Lorenz found that goslings imprint on the first moving object they see during the first two or three days after birth (ordinarily their mothers) and subsequently follow and stay near to that object, apparently because doing so helps ensure their survival. For newly hatched goslings, the first few days following birth is a ____ ____ for imprinting.
Critical Period
Developmental psychologists have identified critical periods for some aspects of ____ ____ in ____, but there is less certainty about their ____ for other aspects of behavior. Consequently, most experts agree that, for many human behaviors (e.g., attachment and language acquisition), there are ____ ____ rather than critical periods.
Physical Development in Humans; Existence; Sensitive Peiords
