Unit 4 Day 7 Review

Scores pile up at the low end of the scale in 

• a negatively skewed distribution
• a positively skewed distribution
• any skewed distribution
• a normal distribution

Dr. Kleiman gives an exam where most of the students receive failing grades and only a few students receive high scores.  When the exam scores are plotted, the distribution will be

• positively skewed
• negatively skewed
• symmetrical
• impossible to predict without more information

When scores are "bunched up"in the center of a distribution, the

• mean will be relatively low

• standard deviation will be relatively low

• correlation coefficiaent will be a negative number

• standard deviation will be relatively high

The symmetric, bell shaped curve that represents the pattern in which many human characteristics are dispersed in the population is known as

• scatter plot
• normal distribution
• frequency polygon
• histogram

What is the purpose of binocular cues?

• To perceive relative distance from an object in one's visual field.

• To organize raw data information from the sensory receptors.

• To interpret information using prior knowledge and past experiences.

• To require two eyes for perception.

What is Weber's Law?

• The minimum amount of stimulation needed to experience a stimulus.

• The minimum change between two stimuli that causes an individual to detect the change.

• The idea that for us to notice a difference between two stimuli, the two stimuli must differ by a constant percent.

• The process of taking in an outside stimulus through one of the senses.

What is the difference between sensory adaptation and habituation?

• Sensory adaptation is the process of becoming less responsive to a continuous stimulus, while habituation is the process of learning from a repeated stimulus.

• Sensory adaptation is the process of filling in missing information for incomplete stimuli, while habituation is the process of becoming less responsive to a continuous stimulus.

• Sensory adaptation and habituation are the same thing.

• Sensory adaptation and habituation are unrelated concepts.

What is the signal detection theory?

• The process of interpreting information using prior knowledge and past experiences.

• The process of organizing raw data information from the sensory receptors.

• The process of predicting if an individual will perceive a weak signal near a threshold level.

• The process of becoming less responsive to a continuous stimulus.

What is the difference threshold?

• The minimum amount of stimulation needed to experience a stimulus.

• The minimum change between two stimuli that causes an individual to detect the change.

• The process of taking in an outside stimulus through one of the senses.

• The ability to perceive relative distance from an object in one's visual field.

What is top-down processing?

• The process of interpreting information using prior knowledge and past experiences.

• The process of organizing raw data information from the sensory receptors.

• The process of perceiving objects based on their simplest form.

• The process of interpreting information using only the information from the senses.
