Psych 100B: Notes from Textbook Chapter 1 Psychological science- study of the mind, brain and behavior Mind: mental activity, person’s perceptual experiences show the mind in action Brain: nerve cells and their associated chemical reactions, which result in mental activity Behavior: actions that occur in all organisms Seven themes of psychological science 1. Psychology is an empirical science Use the scientific method to produce reliable findings 2. Nature and nurture are inextricably intertwined Both one’s biologically innate characteristics and those acquired through education, experience and culture (beliefs, values, norms and customs existing in a group of people sharing a common language and environment) are both important to humans’ psychological development. 3. The brain and mind are inseparable Mind/body problem-are they separate and distinct? Or is the mind the physical brain’s subjective experience? Da Vinci:attempts to link brain’s anatomy with psychological functions (sensus communis [where all sensory images are registered]). -Descartes-dualism (mind and body are separate yet intertwined) rational mind still separate from the body. -Now-mind is what the brain does 1. Biological revolution is energizing research- Brain chemistry-brain works through neurotransmitters, which communicate messages. Scientists have identified these chemicals and their functions. Human genome-Scientists have mapped the basic genetic code and have discovered links between genes and behavior. Watching the working brain- -Neuroscience allows psychologists to determine how brain regions react to produce perception, differences in types of memory and how conscious experience involves changes in brain activity. -Localization of function. 1. The mind is adaptive- -It helps us overcome challenges as well as provides a strong framework for our shared social understanding of how the world works. Adaptations help us survive natural selection. -Many behaviors and attitudes are solutions to recurring human problems (ie: belonging to a group and discouraging social exclusion). -Living in groups > culture > learned by next generation -Culture plays a foundational role in shaping how people view and reason about the world around them. -Different cultures have different views (ie: Western world is more concerned with components while Eastern cultures are concerned with the whole).
