A research on the relationship between teratogens and developmental psychology

Double blind - neither the subject nor the experimenter knows whether the subject is in the treatment of the control condition.

If we had had only the treatment group, we would have no way of knowing whether the reduced anxiety was due to the treatment or the weather, new hospital food, etc.

Why do you think the Riegel and Riegel found that intelligence remains stable until five years prior to death at which point it declines in old age? Conventional moral reason occurs during late childhood and early adolescence and is characterized by reasoning based on rules and conventions of society.

Because the brain develops throughout pregnancy, children could be mentally retarded due to rubella, even if they were neither deaf nor blind,because their mothers had contracted the infection after their eyes and ears had already developed. Below are several topics related to research methodology and the evaluation of developmental research.

Any time you read that a drug is "teratogenic", you should know that means it causes birth defects. Perhaps more of the older group smoked in their early years as compared to the younger group due to increased awareness of the hazards of cigarettes.

While a correlation exists between the two it is not necessarily a cause and effect relationship.

Developmental psychology

Measures that were taken included heart rates before and after blood tests, ease of fluid intake, and self-report anxiety measures. Perhaps an example will help clarify these points. We do know that children who are aggressive tend to watch a higher proportion of violent television than children who are not highly violent or aggressive.

As demonstrated above, the cross-sectional design confounds maturation with cohort. First, there was a treatment and control group.

Therefore, as a methodology it can also only be used descriptively. The longitudinal method is defined by Baltes as follows: This information is very common and is all provided within the college text book and from research found by the University Hospital School of Iowa. Much has been in the news in the past several years concerning violence in schools.

The dependent variable will be measured to determine if the independent variable has an effect. For years, old age was viewed to be a period of major health problems, depression, isolation, and severe cognitive decline as the research subjects consisted of elderly living in nursing homes!

For example, if a study has a pretest, an experimental treatment, and a follow-up posttest, history is a threat to internal validity. The studies conducted reporting a drop in intelligence with increasing age may be simply the reporting of a selection bias - the subjects samples were in long-term care and thus, non-well.

Much of the research conducted by developmental psychologists is quasi-experimental.

Teratogens

The traditional designs, such as those described above, examine only one dependent variable. First, the longitudinal method rarely meets the criteria of selective sampling Baltes, Your textbook does mention the most common teratogens, but I want to cover these in more depth and emphasize these because this information is SO important and in my opinion cannot be stressed enough.

April Learn how and when to remove this template message Nature vs nurture[ edit ] A significant issue in developmental psychology is the relationship between innateness and environmental influence in regard to any particular aspect of development.

If a study has good statistical conclusion validity, we should be relatively certain that the answer to these questions is "yes". It is often easier to impose this sort of control in a laboratory setting. One of the ways this relationship has been explored in recent years is through the emerging field of evolutionary developmental psychology.A significant issue in developmental psychology is the relationship between innateness and environmental influence in regard to any particular aspect of development.

embryology and the neuroscience of prenatal development is of increasing interest to developmental psychology research. Several environmental agents—teratogens—can.
