Event - Event Learning
Classical Conditioning
Pavlovian Conditioning
In the following 4 examples You will experience two
events. Press the space bar to see the two events.
When this appears
click it to go to
the next example
For each example jot down on a piece of paper
the relationship, if any, between the two events.
That is, try to determine whether the appearance
of one of the events is related to the appearance
of the other event?
When all four examples are finished, time lines
will be provided that depict the events in the 4
examples.
Two events will occur. Are they
related in any way? #1

Time Lines
The next slide shows time lines which describe the
relationship between the two events.
Each example contained the same events (a light bulb
and bomb) occurring for the same duration (1/2 sec)
and the same number of times (5). The interval of time
between trials (ITI) was fixed at 10 seconds. The
examples varied only in terms of the interstimulus
interval (ISI) - the interval of time between the light
bulb and bomb. In all except the first example, the
light bulb preceded the bomb.
DID you experience the two events as related in each
example? If not, rate the examples from the most
related to the least.
Trace Conditioning Time Lines
Event A = Light Bulb; Event B = Bomb
ITI = 10 sec; # of trials = 5; ISI is Manipulated (IV)

Study the time lines on the previous slide and
compare them with the notes you jotted down
while viewing the examples. Briefly describe
how your perceptions of a relationship
between two events is influenced by the ISI
that was manipulated in this brief experiment.
