EXPERTISE- knowledge base. Have to have some skill in the area. (ex. painting- if you don't know different paints it wont work, etc.) Furnishes the ideas, images, and phrases we use as mental building blocks. IMAGINATIVE THINKING SKILLS- have to think outside the box. Provide the ability to see things in novel ways, to recognize patterns, and to make connections. A VENTURESOME PERSONALITY- curious, risk-taker. Have to be willing to take risks. Seeks new experiences, tolerates ambiguity and risk, and perseveres in overcoming obstacles. INTRINSIC MOTIVATION- have to want to do it for themselves; you love it. (eg. Sara Bareilles- "Love Song") Being driven more by interest, satisfaction, and challenge than by external pressures. A CREATIVE ENVIRONMENT- environment that cultivates creative thinking. It will make you more creative. Sparks, supports, and refines creative ideas.

Priming
Masking stimulus. Occurs below your level of consciousness, but can occur when you're conscious (above or below). Being exposed to a sensory stimulus consciously or unconsciously that affects your actions. The retrieval process is aided for an individual if they have been exposed to a stimulus previously. This prior exposure or priming will make it more likely that they will recall that same or similar stimulus later. The activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response.

Signal-Detection Theory
Theory predicting when we will detect stimuli from noise based on expectations, experience, motivation, and alertness. Ration of "hits" to "false alarms." The theory used by psychologists to evaluate how accurately individuals notice faint stimuli under a variety of conditions. Whether or not an individual notices a faint stimulus depends on the stimulus itself, the background stimulation, and characteristics of the individual including their level of attention, motivation, and experience.
Elaboration Likelihood Model
Theory suggesting that there are two routes to attitude change: the central route, which focuses on thoughtful consideration of an argument for change, and the peripheral route, which focuses on less careful, more emotional, and even superficial evaluation.
Signal Detection Theory
Theory that holds that an observer's perception depends not only on the intensity of a stimulus but also on the observer's motivation, the criteria he or she sets for determining that a signal is present, and on the background noise.
Observational Learning Theory
Theory that suggests that organisms learn new responses by observing the behavior of a model and then imitating it; aka. Social learning theory

Cognitive Neuroscience
What is going on in the brain, what the brain is doing while thinking. The interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language).
Young-Helmholtz Trichromatic Theory
Three color. Three forms of cone receptors that fire in response to red, green, or blue. Respond to different wave-lengths. Lead to all color. Stimulation of all three of these colors- white. Color we see- reflect off. All other colors are absorbed. The theory of color vision that states that there are three types of color photoreceptors (cones) in the retina of each eye that are either most sensitive to red, free, or blue wavelengths. All of the colors of the visible spectrum can be perceived by combining these three reflected wavelengths.
Weber's Law
To perceive a difference, two stimuli must vary by a constant percentage/proportion (NOT amount). ex. Weightlifting- add 5 to 300 lbs; no difference. Add 5 to 20 lbs; more difference. The formula for determining the just noticeable difference that states that the minimum amount of change needed to create a just noticeable difference is a constant percentage of the original stimulus. Larger stimuli require greater increases in intensity for a difference to be notice. It is effective for predicting the JND for most senses over a wide range of intensities, but it does not work as well for extremes.
Latent Learning
Tolman- came up with this. Rats and maze. Hidden (latent) learning. Learning that occurs but is not apparent until there is an incentive to demonstrate it.
