introduction to biological Flashcards
biological psychology
how your biological systems in your body affect your behavior
how is tiredness caused

heart rate increases
blood pressure increases

reductionism
idea that we study 1 factor that influences behavior at a time
holism
idea that we should try to study many factors that influence behaviors at once
reductionism strengths
- more scientific as if involves experimental methods including isolating a variable
- can be useful when identifying a single factor that can influence behaviors
reductionism weaknesses
- human behavior is too complex to be reduced down to a single factor
- manipulating the effect of single factors often results in controlled experimental research which lacks ecological validity
strengths of holism
- helps see behaviors which only energy from different how different factors interact
-gives a greater understanding of causes of behavior due to taking account several different influences (increasing validity )
weakness of holism
-more difficult to make predictions about hey ai our due to not knowing which of many factors is the most important
- less scientific as it difficult to establish cause and effect when investigating the interaction of different factors
