PSYC 160 Lecture Notes - Teratology, Low Birth Weight, Preterm Birth
Document Summary
A teratogen is an environmental agent such as a drug, chemical, virus or other factors with the potential for producing birth defects. During early phases of development, a teratogen might have signi cant consequences. During later phases of development, the impact might be minimal. The extent of a birth defect tends to be determined by the. "timing of exposure" and the "quantity of exposure" to one or more teratogens. The following teratogens and associated e ects supplement the discussion of threats to prenatal development on pages. Teratogens associated e ects. Alcohol intellectual retardation. Ca eine spontaneous abortion (miscarriage) Cocaine learning di culties. Marijuana low birth weight. Amphetamines aggressive behavior (post-natally) Nicotine premature birth. Note #1: when learning a 6-item or longer serial/list, divide the list. Two 3-item serials/lists can be learned more quickly and more accurately than learning a 6-item serial/list. Note #2: the above teratogens and associated e ects are formatted as "paired-associates".
