  2. 1st quarter exam • Review missed questions individually. • Write correct answers in complete sentences…EXCEPT number 7 & 76. The correct answers are C & basilar membrane. • Six-question curve (including 7 & 76).

  3. Kinesthesis vs. Vestibular Sense • Kinesthesis: using touch to sense your body’s placement and movements (e.g. skin) • Vestibular sense: using mechanisms in the head to monitor your body’s balance and movement (e.g. semicircular canals)

  10. Illusions • All examples of selective attention. • The cocktail party effect is another example of selective attention.

  11. Figure-Ground relationship • Your interpretation of an image adjusts your figure (what stands out) and your ground (the surroundings). You can reverse your figure and ground with some illusions—this phenomenon is related to the figure-ground relationship, or how we organize our visual fields into these groups. • This concept is also known as multistability—our experiences switch back and forth between interpretations. • Face vase is the best example.

  16. Attention & Perception • Explain in one paragraph how attention can impact perception of sensations. Use specific examples.

  17. Visual capture • When the brain gets conflicting sensations, the sense that wins out is visual. This principle is called visual capture. • Ventriloquism is the most common example of visual capture.

  18. Gestalt psychology • Gestalt is German for “whole.” • Humans have a tendency to organize visual sensations into grouped perceptions. This is called grouping. • “The whole is different than the sum of the parts” – e.g. a cookie, a basketball team, etc. • Central concept: Law of Pragnanz, or the Law of Simplicity. Humans tend to order experiences in a way that is regular, symmetric, and simple.

  22. Gestalt: Connectedness
