Yerkes Dodson Law
• There is this “best” level of arousal for
performance (too low/high reduces it)
– High arousal levels = higher performance if…
• The task becomes easier
• You are more experienced
• Presence of observers
– Think roaches

themselves

Perception: Audition
• 20-20,000 Hz = normal range
• Most speech sounds occur in central range (most
sensitive)
• Transduction from physical signal  neural signal
occurs at basilar membrane
• Frequency (Volley) theory: frequency of the AP tells
the actual frequency in the real world (problem: AP can
only fire ~ 1000 times/sec.)
• Place theory: location of the depolarizing hair cells on
the basilar membrane tells the frequency of the sound
in the real world

horseshoe crab)

surrounded by darkness (or light) in a particular

retinal ganglion cells connecting to a brain cell

experiences.

experience.

Weaknesses of Piaget’s theory

gradually or incrementally

Information-Processing Theories
• Thinking = information processing
– Representation of information
– Processes - applied to representations
– Constraints - memory limits constrain representation and
processing
• Cognitive development = advances in their ability
to process and respond to the information
they received through their senses
• Emphasizes a continuous pattern of
development (different from Piaget’s stages)

Attachment Styles
• Secure - Uses caregiver as a secure base for exploration.
Upset by departure of parent but easily calmed when
they return and can continue to play.
• Resistant – Does not use parent as a secure base, often
stays close to them. Upset when they leave but not
comforted by their return.
• Avoidant – Little affect while playing. No visible stress
upon parents departure, ignores them on return. Treats
the stranger similarly to the caregiver.
• Disorganized – no clear attachment patter. Show freezing
or repetitive behavior.

Moral Development: Kohlberg
A woman was near death from a special kind of cancer. There was
one drug that the doctors thought might save her. It was a form
of radium that a druggist in the same town had recently
discovered. The drug was expensive to make, but the druggist
was charging ten times what the drug cost him to produce. He
paid $200 for the radium and charged $2,000 for a small dose
of the drug. The sick woman's husband, Heinz, went to
everyone he knew to borrow the money, but he could only get
together about $1,000 which is half of what it cost. He told the
druggist that his wife was dying and asked him to sell it cheaper
or let him pay later. But the druggist said: “No, I discovered the
drug and I'm going to make money from it.” So Heinz got
desperate and broke into the man's store to steal the drug for
his wife. Should Heinz have broken into the laboratory to steal
the drug for his wife? Why or why not

Characteristics of Attitudes

different properties that determine the
likelihood of attitude change (characteristics
of the source, characteristics of the message,
