Availability:Ease of amount of recall?
The study of Schwarz et al. (1991)
It has been shown that people overestimate the
frequency of men resp. women if the names of one
sex, but not the other, were very famous and thus
highly available (Tversky and Kahneman, 1973);
Availability was measured by how many names
participants were able to recall.

There are two ways how to explain this finding:
(1) The number of famous names was overestimated
because participants recall more of them (how Tversky
& Kahneman measured availability).
(2) The number of famous names was overestimated
because participants recall them more easily (how
Tversky & Kahneman defined availability).

Experiment:
The participants had to list either six or twelve
episodes from their own lifes in which they were
self-assertive. It is easier to recall six such
behaviors, but amount of recall is higher with
when twelve such behaviors can be listed.
Afterwards, they had to rate their self-
assertiveness.

Hypothesis:
(1) If participants use the amount of recall as information, they
are expected to feel themselves more assertive after recalling
twelve rather than six self-assertive episodes.
(2) If participants use the ease of recall as information, they are
expected to feel themselves more assertive after recalling six
rather than twelve self-assertive episodes.

The results show clearly that participants use ease of
recall as information:
They judged themseves to be more assertive after
recalling six rather than twelve self-assertive
behaviors.

In another condition, participants were asked to list either six
or twelve episodes from their own lifes in which they behaved
unassertive.
If participants again use ease of recall, they are expected to
rate themselves as being more assertive after recalling twelve
rather than six unassertive behaviors.

In other words: If it is so easy to recall six unassertive
behaviors, I can‘t be too assertive after all; and if it is so
difficult to recall twelve unassertive behaviors, I must be
quite assertive!

Again, participants use ease of recall as information when
judging self-assertiveness.
In order to examine the underlying processes, Schwarz et al.
(1991) replicated the former experiment, but played meditation
music in the background.

In one condition, participants were told that the music
facilitates the recall of assertive behaviors, whereas the
other participants were told that music facilitates the recall
of unassertive behaviors.

Predictions:
Participants whose subjective experience contradicted the alleged
side effect of the music would consider this experience particularly
diagnostic and would use it in their self-assessment, whereas
participants whose experience was in line with the alleged side
effect of music would discount the experience and use amount of
recall instead.
If participants did not use ease of recall as information, diagnosticity
of experienced ease would not change self-assessments.

For example, if participants had to recall six
assertive behaviors and were told that music
facilitates the recall of assertive behaviors, they
think that ease of recall is due to music and
discount the experience; for them, experienced
ease is not diagnostic as information for the
judgment of assertiveness.

However, if they had to recall six assertive
behaviors and were told that music facilitates
the recall of unassertive behavior, ease of
recall becomes highly diagnostic because the
expectation that music facilitates unassertive
behaviors contradicts the experience of ease of
recalling assertive behaviors.

When diagnosticity of experienced ease of recall
was high, participants relied on ease of recall, as in
the former study. However, if diagnosticity of
experienced ease of recall was low, participants
relied on amount of recall.
The authors interpreted this pattern of findings as
evidence that ease of recall, and not some other
information, causes variations in assertiveness
ratings.

Besides diagnosticity of recall, other variables have been
found that moderate the effects of experienced ease of recall
on judgments:
Processing motivation (Rothman & Schwarz, 1998);
Direct access to information in memory
(Haddock et al., 1999);
Naïve theories about the meaning of experienced ease of
recall (Winkielman & Schwarz, 2001).

Ease of recall has been shown to influence several types of
variables:
Frequency estimates (Wänke et al., 1995)
Judgments of risk (Grayson & Schwarz, 1998; Rothman &
Schwarz, 1998)
Attitudes toward a product (Wänke, Bohner, & Jurkowitsch,
1997)
Debiasing hindsight (Sanna, Schwarz, & Stocker, 2001).
