(0.00 to 1.00)
Normal
Curve
The mean, median, and mode of a
normal distribution are identical and fall
exactly in the center of the curve. This
means that any score below the mean
falls in the lower 50% of the distribution
of scores and any score above the
mean falls in the upper 50%. Also, the
shape of the curve allows for a simple
breakdown of sections. For instance,
we know that 68% of the population fall
between one and two standard
deviations (See Measures of Variability
Below) from the mean and that 95% of
the population fall between two
standard deviations from the mean.
Figure 8.1 shows the percentage of
scores that fall between each standard
deviation.
Skewed Distribution
An asymmetrical distribution of scores, such as a curve with a bump on the left and
tail to the right or most scores are bunched to the left or right of the mean
• The mean is the largest or the mode or median are smaller than the mean
• The mean is a less useful measure; while the median is more useful

Measures of Variability
Indicate the dispersion or spread in a data set. How much the scores
in a set of data vary from:
a. Each Other
b. the Mean
Tell you if the scores are very different from one another or if they
cluster around the mean.
Range
The difference between the highest and lowest score in a set of data.
Extreme scores can radically affect the range of a data set.
Standard Deviation
Reflects the average distance between every score and the mean. Tell
you how different the scores are from the
mean. Tells you whether scores are
packed together or dispersed. Increase
variability = increase in standard
deviation
Statistical Significance
Results are “statistically significant” when the probability that the
findings are due to chance is very low. EX: If the difference
between two group means is statistically significant, a researcher
would conclude that the difference most likely exists in the population
of interest. If the difference is not statistically significant,
a researcher would conclude that the difference occurred by chance –
possibly because of an unrepresentative sample or
the presence of confounding variables.
“Very Low” means less than 5 chances in 100
or
P < 0.05 level of significance

and the pituitary
gland also respond
to stress (slow) by
triggering the outer
adrenal glands to
secrete
glucocorticoids
(cortisol).
52
The Stress Response System
Canon proposed that
the stress response
(fast) was a fight-orflight response marked
by the outpouring of
epinephrine and
norepinephrine from the
inner adrenal glands,
increasing heart and
respiration rates,
mobilizing sugar and
fat, and dulling pain.

Sensing the World: Basic Principles
•
Difference Threshold (just noticeable difference or jnd) = the lowest difference
between two stimuli that person can detect 50% of the time.
– Weber’s Law = regardless of magnitude, two stimuli must differ by a constant
proportion for the difference to be noticeable.
• Light intensity – 8%
• Tone frequency - .3%
• Weight – 2%
– EX: Lemon Lab – if you lemon weighs 6 oz then the next lemon will have to
weigh .12 oz heavier or .12 oz lighter in order to detect the difference
between lemon
– JND varies according to the strength or intensity of the original stimulus. The
greater the stimulus the greater the change necessary to produce JND
• EX: If a farmer grows giant lemons, a greater difference threshold will be
needed to determine a change from a 500 oz lemon, such as a change of
10 oz versus .12 oz with a 6 oz lemon.
Sensing the World: Basic Principles
•
Difference Threshold (just noticeable difference or jnd) = the lowest
difference between two stimuli that person can detect 50% of the time.
– Fechner’s Law – larger and larger increases in stimulus intensity are
required to produce perceptible increments in the magnitude of
sensation. Constant increments in stimulus intensity produce smaller
and smaller increases in perceived magnitude of sensation.
•
Scene #1: dark room – add one light bulb – difference in light is striking
•
Scene #2: same room – add a second light bulb – the amount of light is
doubled but the room does not seem twice as bright
•
Scene #3: same room – add a third light bulb, it adds just as much light as
the second, but you barely notice the difference
– Three equal increases in stimulus intensity produces progressively
smaller differences in the magnitude of sensation
Visual Processing: light waves cornea pupil (iris) lens retina (rods and
cones – trichromatic theory bipolar ganglion – start of opponent process)
optic nerve (blind spot) thalamus occipital lobe (visual cortex – end of
opponent process) feature detectors abstraction (cells in parietal and
temporal lobe combine info from feature detectors) PERCEPTION
Theories of Color Vision: Trichromatic Theory

Pitch – high or lowness of sound
• The greater the number of cycles per second, the higher the pitch.
Longer the wave = lower the pitch / Shorter the wave = higher the
pitch
• Frequency – number of cycles per second as expressed in the unit Hertz.
• Hertz – A unit expressing the frequency of sound waves. One Hertz, or 1Hz,
equals one cycle per second.
• Human hearing  detect sounds ranging in frequency from 20Hz –
20,000Hz
Loudness
• The higher the amplitude of a wave, the louder the
sound.
• Amplitude – strength or height of wave.
• Decibel – A unit expressing the loudness of a sound,
abbreviated dB.
• Perceived loudness doubles about every 10 decibels. The
absolute threshold for hearing is arbitrarily defined as 0
decibels.
Perceiving Pitch
Place Theory (Traveling Wave Theory)
= pitch determined by point of maximal vibration on basilar membrane.
Different pitches activate different places of the cochlea’s basilar membrane.
Only applicable to high pitched sounds – over 5000 Hz
(low pitched sounds do not localize as well)
Frequency Theory
= frequency of a tone (or pitch) matches the rate
at which the hair cells fire or the rate of nerve impulses
traveling up the auditory nerves (i.e., 1KHz tone cause
hair cells to fire 1k times/sec)
Only applicable to sounds under 1000 Hz
(individual neurons cannot fire faster than 1000 times/sec)
Volley Theory
= receptors in the ear fire in sequence. Several
neurons together, firing in sequence, can send a
more rapid series of impulses to the brain than one.
Touch
Sensory receptors located around the roots of hair cells fire when surface of
skin is touched (mechanical and thermal energy).
The sense of touch is a mix of four distinct skin senses—pressure, warmth, cold,
and pain.
Only pressure has identifiable receptors. All other skin sensations are variations
of pressure, warmth, cold and pain.
Two pathways: #1 – signals from thermal receptors + pain signals; #2 – signals
from tactile stimulation (pressure)
Hot = warm ( firing) +cold
( firing)
Wet = pressure + cold
Tickling itch = pressure +
pain
68
Sensory Homunculus
Homunculus - Latin for "little
human“; any representation of a
human being.
The Motor Cortex is the area
at the rear of the frontal
lobes that control voluntary
movements. The Sensory
Cortex (parietal cortex)
receives information from
skin surface and sense
organs.
Gate-Control Theory
Spinal cord contains neurological “gates” that
either block pain or allow it to be sensed.
•
•
•
•
Small fibers (pain + temp) = open gate =
pain. When tissue is injured, the small
fibers activate and open the neural gate
– Slow pathway – lags a second or two
behind the fast system; longer
lasting, aching pain
– Fast pathway – registers pain and
relays it to the cortex in a fraction of
a second
Large fibers (tactile – pressure or
vibration) = close gate = no pain.
– Stimulate (massage, rub,
acupuncture) gate closing activity to
treat pain.
– Also closed by signals from the brain
– attention and expectations
Endorphins can also close gate
Brain (attention and expectations) also
close gate

Fundamental Attribution Error
• How we explain someone’s behavior affects how we
react to it
Situational attribution
“Maybe that driver is ill.”
Tolerant reaction
(proceed cautiously, allow
driver a wide berth)
Dispositional attribution
“Crazy driver!”
Unfavorable reaction
(speed up and race past the
other driver, give a dirty look)
Negative behavior
Cognitive Dissonance
Social Facilitation/Interference
• Linked social
interference and
facilitation to arousal
level
• High arousal improves
simple or well-learned
tasks
• High arousal worsens
complex or poorlylearned task
Presence of others
Increased drive or
arousal
Improved performance
of dominant responses
(social facilitation)
Worsened performance
of nondominant responses
(social Interference)
Group Polarization
example: risky-shift effect
• groups with a tendency to take risks exaggerate risk-taking decisions
• groups with a tendency to be conservative exaggerate safe responses
