how and why people change across a life span

the science of human developement best be described

Operant Conditioning

is the process by which a response is gradually learned through reinforcement or punishment


is the process by which a particular action is followed by something desired, which makes the person or animal more likely to repeat the action.

Social learning theory

an extensionof behavorism, emphasizes that people often learn new behavoris through observation and imitation of other people


emphasizes that the way people think and understand the world shpaes their attitudes, beliefs, and behavoirs.

Ecological systems approach

to develope mental research takes into consideration the interrelationship between systems within the person and the environment

Dynamic systems theory

views human development as in a constant state of flux and as the product of the interaction between systems within the person and the environment.

Scientific Observation

is the unobtrusive watching and recording of participants behavoir in a systmatic and objective manner. either in the laboratory or in a natural setting.


is the research method designed to untangle cuase from effect by manipulating one variable to observe the effect on another variable.

Independent variable

is the variable that is manipulated in an experiment to observe what effect it has on the dependent variable.

Dependent variable

is the variable that may change as a result of whatever new condition or situation is added in an experiment. new drug on memory particpants memory is the dependent


is the research method in which information is collected from a large number of people, either through written questionnaires, personal interviews, or some other means.

cross sectional research

groups of people who differ in age but share other important characteristics are compared with reard to the variable under investigation

logitudinal research

follows a group of people of different ages over time. thus combining the strengths of the cross sectional and longitudinal methods.


is a number indicating the degree of relationdship between tow variables, such that one is likely to occur when the other occurs or one is likely to increase or decrease when the other increases or decreases

Quantitative research

expressed in numbers

qualitatitve research

collects non numerical descriptions of participants characteristics behavoir and ideas

Science of human development

seeks to understand how and why all people, everywhere change or remain same over time

Scientific Method

is a way to answer questions that requires empirical research and data based conclusions. The five basic steps are- pose a research question, develop a hypothesis, test the hypothesis, draw conclusions, report results which allows replication


means to repeat a test of a research hypothesis and to try to obtain the same results using different participants.

Psychoanalytic theory

- interprets human development in forms of inner drives and motives, many of which are irrational and unconscious.


- studies observable behavior, it is also called learning theory because it describes that laws and processes by which behavior is learned.


is the learning process that occurs either through the association of two stimuli (classical Conditioning) or through the use of positive or negative reinforcement or punishment (operant conditioning)

most human traits; they are affected by many genes.


most human triats are that is influenced by many factors, including genetic and environmental factors.

additive genes

the phenotype reflects the sum of the contributionsof all the alleles invovled. The allesles affecting height for example, interact in this fashion

dominant recessive pattern

is the interaction of a pair of alleles in such a way that the phenotype reveals the influence of the dominate gene more thanthat of the recessive gene.

Carrier of that gene

a person who has a recessive gene that is not expressedin his or her phenotype but than can be passed onto the person offspring


is a stastic that refers to the percentage of variation in a particular trait within a particular population, in a particular context and era that can be traced to genes.

Down Syndrome

is the most common extra chromosome condition. people with down syndrome age faster than others often have unusaual facial features and heart abnormilites and invarialby develope Alzheimers disease
