Human Development and Behavior in the Social Environment Flashcards
Autonomic Nervous System (ANS)
A division of the peripheral nervous system that is involved in the control of visceral functions (e.g., heart rate, blood pressure, respiration, digestion, and sweating). Consists of the sympathetic and parasympathetic branches
Buffering Hypothesis
The hypothesis that lower susceptibility to stress, greater life satisfaction, and other positive outcomes are associated with a perception that one has adequate social support
Coercive Family Interaction Model
Proposes that children initially learn aggressive behaviors from their parents who rarely reinforce prosocial behaviors from their parents who rarely reinforce prosocial behaviors, use harsh discipline, reward their children’s aggressiveness with approval and attention and that, over time, aggressive parent-child interactions escalate. Patterson and colleagues developed a parent intervention designed to stop this coercive cycle by teaching parents child-management skills and providing them with therapy to help them cope more effectively with stress
Contact Hypothesis
Proposes that prejudice may be reduced through contact between members of the majority and minority groups as long as certain conditions are met (e.g., members of the different groups have equal status and power and are provided with opportunities that disconfirm their negative stereotypes about members of the other group)
Differential Reinforcement
Differential reinforcment (e.g., DRA, DRO, and DRI) is an operant technique that combines positive reinforcement and extinction. During a specified period of time, the individual is reinforced when he/she engages in behaviors other than the target behavior. The alternative behaviors are reinforced, while the target behavior is extinguished
Ego
As defined by Freud, the structure of the psyche that attempts to deal with reality in a practical, rational way (secondary process thinking) and that mediates the conflicting demands of the id, the superego, and reality; the “executive function” of the personality. Operates on the basis of the reality principle
FI (Fixed Interval) Schedule
In operant conditioning, an intermittent reinforcement schedule in which the subject is reinforced for each predetermined interval of time in which he/she makes at least one response. Associated with a “scallop” on the cumulative recording of the subject’s responses
Genotype Versus Phenotype
Genotype’ refers to a person’s genetic make-up; “phenotype” refers to observable characteristics, which are due to a combination of genetic and environment factors.
Hemispheric Specialization
Although the left and right hemispheres of the brain are both involved to some degree in most functions, they tend to specialize. The left (dominant) hemisphere dominates in verbal activities (e.g., spontaneous speaking and writing, memory for words and numbers); analytical, logical thought; and positive emotional states. The right (nondominant) hemisphere dominates in visual-spatial activities such as facial recognition, spatial interpretation, and memory for shapes and in negative emotions
Hyperthyroidism
A condition caused by hypersecretion of thyroxine by the thyroid gland and characterized by a speeded-up metabolism, elevated body temperature, accelerated heart rate, increased appetite with weight loss, nervousness, and insomnia
Institutional Racism
The denial or restriction of material conditions (e.g., access to health care) and access to power to members of minority groups
Latent Learning (Tolman)
Proposes that learning can occur without reinforcement and without being manifested in actual performance improvement. Tolman’s research showed that rats formed “cognitive maps” of mazes even without being reinforced for doing so.
Natural Social Networks
Consist of family, friends, neighbors, and coworkers who exchange emotional support and other resources in times of need. When effective, they make it unnecessary for an individual to turn to institutionalized services offered by social agencies. Because geographically dispersed social networks depend on linkages such as transportation, they may be vulnerable in times of crisis
Norms
The standard rules of conduct used by groups to maintain uniformity of behavior among group members. Norms may be formal (codified or written) or informal (unwritten but “understood” by group members). Norms do not govern all aspects of behavior, only those considered by the group to be important for effective group functioning. In addition, norms usually apply to behavior not to personal feelings and thoughts
P.L. 94-142 (Education For All Handicapped Children Act)
Guarantees an appropriate free public education to all children ages 3 to 21 who need special education services. An individualized educational program (IEP) must be developed for each student with a qualifying disability. The IEP is written by schoo; personnel in collaboration with the student’s parents and must provide the least restrictive environment for the student ( the environment must be as similar as possible to the regular classroom setting, taking into account the nature of the student’s disability). Over time, P.L. 94-142 has been amended, and in 1990, it was renamed the Individuals with Disabilities Education Act, or IDEA, (P.L. 101-476)
Phenylketonuria (PKU)
Potential cause of intellectual disability due to an inability to metabolize the amino acid phenyalanine. Can be prevented by providing a diet low in phenylalanine
Percipitating Factor (Crisis)
The final stressful event in in a series of events that moves a person from a state of acute vulnerability into crisis. The precipitating factor is often a minor event but it can assume catastrophic proportions in the context of other stressful events and the person’s inability to use his/her usual problem-solving strategies
Protective Factors
Protective factors coexisting with risks are personal, social, and institutional factors that promote personal competence and successful development and, thereby, decrease the likelihood of a problem occurring. Examples include adequate prenatal care, active coping mechanisms, and low family stress
Racism (Levels of Racism)
Racism is a system of power and privilege that may be manifested in attitudes, behaviors, and/or institutional structures based on people’s skin color. Levels of racism include institutional racism (denial or restriction of material conditions and access to power to members of minority groups); personally mediated racism (prejudice and discrimination at the individual level); and internalized racism (acceptance by members of the stigmatized races of negative messages about their own abilities and intrinsic worth)
Rutter’s Indicators
Rutter argues that the greater the number of risk factors a baby is exposed to, the greater the risk for negative outcomes. He concludes that the following six family risk factors are particularly accurate predictors of child psychopathology: severe marital discord, low socioeconomic status, overcrowding or large family size, parental criminality, maternal psychopathology, and the placement of a child outside the home
Separation Anxiety
A normal fear response exhibited by a young child when he/she is separated from his/her mother or other primary caregiver. Begins at about 6 to 8 months, increases in intensity at about 14 to 18 months, and thereafter declines
Sociocultural Risk
Exists when a child lacks the basic material, social, and psychological necessities of life (e.g., food, water, shelter, love, and affection, medical care, educational stimulation, positive social interactions). Children (and adults) who lack all or some of these necessities are at risk for impaired development and other deficiencies. Two key sources of sociocultural risk are “social impoverishment” (lack of critical social resources in a child’s life) and “cultural impoverishment” (values that undermine a child’s healthy development)
Superego
For Freud, the structure of the psyche that represents society’s standards of right and wrong (the conscience) and the individual’s own aims and aspirations (ego ideal). Develops at age 4 or 5 years, primarily as the result of identification with one’s parents
Unconditioned Response (UR)
In classical conditioning, the response naturally elicited by the unconditioned stimulus (US) without conditioning
