Simplified version of Experiment 2
Subjects were informed that the main purpose of the experiment was to study an aspect of memory
The final recognition test was expected.
Encoding was intentional rather than incidental.
Words were presented serially on a screen at a 6-sec rate;
during each 6-sec interval subjects recorded their response to the encoding question
1 second for presentation of the word and a 5-second interword interval
Previous experiments (strict rigor):
Subjects were told that the experiments concerned perception and reaction time
Words exposed for 200 milliseconds
The point of this study was not to attack experimental rigor, but rather to determine to what extent the now familiar pattern of results would emerge under these much looser conditions.
Method:
All subjects saw the same sequence of words.
But they were asked different questions.
Example word: copper
Question 1: Is the word a metal?
Question 2: Is the word a kind of fruit?
Question 3: Does the word rhyme with STOPPER?
For each word, 6 questions were asked.
Case
Rhyme
Yes x No
Category
They were presented with the words in booklets
20 questions per page
Participants first studied the questions, then were presented with the word and answered accordingly by ticking "yes" or "no".
After 60 encoding trials, participants received a recognition task sheet with 180 words; 60 words that were presented to them and 120 distractors.
There were 2 different randomisations of the recognition sheet.
Instructions to subjects:
Emphasise on main task being to remember the words
They were told that they'd be given a recognition task sheet after the words were presented
Results
Quite similar to experiment 2
