Notes Weeks 2 and 3 Class Notes:  Confounding- ex: increase in ice cream consumption and increase in violence- link = temperature/heat (or ex: absences and good grades have a negative correlation)  Operational definition- what exactly are the research variables we are working with  Placebo- inert/non-active substance; sugar pill  Repeat research study in different situations and in same one to give legitimacy to experiment  Case study- hopes of revealing a universal principle  Significance testing- size of difference in means of two or more groups (experimental and control)  Null-hypothesis testing- there is no meaningful difference between groups  Type I error- we believe there’s a meaningful effect when there’s not  Type II error- thinking there’s no effect when there is  Survey- self assessment data in random group  False consensus effect- tendency to overestimate extent to which others share our beliefs and behaviors  Naturalistic observation- without trying to manipulate or control the situation, just observing  Scientific research vs. non-scientific  Systematic approach  Repeatable  Objective (no biases)  Interpretations based on data and observations rather than common sense  Biological determinism- mind and personality = genes, brains, hormones (behavior determined by bio tendencies)  Neurons consist of dendrites and axons and cell body  Dendrites- short appendages that receive messages  Axons- long appendages that send messages to other parts of body  Electrical impulses- action potential  Then, electrical messages  chemical  Individual differences- genetics and environment  Darwin:  Super abundance- more offspring than necessary  Variation- differences in offspring  Natural selection- characteristics that allow adaption which lead to reproduction  Emotions manifested as personality traits  Rapid orientation to events in environment  Organization- coordination between muscles, respiratory, cardiovascular, facial expressions  Adaptation- respond to pressures, survive, reproduce  Evolutionary theory not testable- predictive and explanatory power, morality and consequences not a concern  Brain uses 25 percent of energy from the body Chapter 3 Class Notes:  Consciousness- levels of awareness of self and environment  Cognitive neuroscience- study that attempts to link brain activity with mental processes (perception, thinking, memory, language)  Continuum of consciousness- range of experiences from aware to unaware/unresponsive  Altered states of consciousness  Normal/waking awareness  Daydreaming  Sleeping  Meditative states  Drug induced states  Other ?  Dual processing- ability to process info (organize and interpret) on two levels 1. Conscious, internal processing:  Parallel processing- normal multitasking  Sequential- consecutive and ordered execution of processes one after another; requires focused attention  Unconscious parallel- faster 2. Unconscious, automatic processing- without thought (ex: strong emotions, dreaming, doing things on autopilot)  Selective attention- focusing of conscious awareness on a stimulus  Cocktail party effect- able to attend to one out of many voices, but having been perceiving other stimuli all along without realizing; background noise concept  Sleep- Arcadian rhythm
