Objectives: In this article, we explore two manipulations of “meaning
response,” intended to either “impart” meaning to participants through
the manipulation of a few words in the test instructions or to “invite”
meaning by making the participant feel involved in the setting of their
preferred sound.
Design: In experiment 1, 59 adults with normal hearing were randomly
assigned to one of the two groups. Group 1 was told “this hearing in
noise test (HINT) you are about to do is really hard,” while the second
group was told “this HINT test is really easy.” In experiment 2, 59 nor-
mal-hearing adults were randomly assigned to one of two groups. Every
participant was played a highly distorted sound file and given 5 mystery
sliders on a computer to move as often and as much as they wished
until the sound was “best” to them. They were then told we applied their
settings to a new file and they needed to rate their sound settings on
this new file against either (1) another participant in the study, or (2) an
expert audiologist. In fact, we played them the same sound file twice.
Results: In experiment 1, those who were told the test was hard per-
formed significantly better than the easy group. In experiment 2, a sig-
nificant preference was found in the group when comparing “my setting”
to “another participant.” No significant difference was found in the group
comparing “my setting” to the “expert.”
Conclusions: Imparting or inviting meaning into the context of audio-
logical outcome measurement can alter outcomes even in the absence of
any additional technology or treatment. These findings lend support to a
growing body of research about the many nonauditory factors including
motivation, effort, and task demands that can impact performance in our
clinics and laboratories.
Key words: Meaning, Expectations, Hearing, Placebo, Audiology.

INTRODUCTION
“Meaning responses” can be defned as a change in perfor-
mance, outcome, and/or preference that is governed by factors that
are not necessarily related to the treatment of interest (i.e., motiva-
tion, effort, task demands, the surrounding context in which you
fnd yourself, personal beliefs and biases, the narrative you tell
yourself about experiences, etc.; Moerman & Jonas, 2002).
Meaning in Health Care
Treatment in health care is largely considered a means of
counteracting the pathology of a disease often through the use of
pharmacological approaches, therapy, and/or surgery. However,
treatment rarely happens in isolation without the direct involve-
ment of a clinician and the context and situational infuences
that are available in the treatment environment (Naylor et al.,
2015). There is a large body of literature that shows meaning
responses can have a substantial infuence on physiological and
psychological performance (for a thorough review of mean-
ing responses see Moerman and Jonas (2002)). The authors
defne meaning response as “the physiologic or psychological
effects of meaning in the origins or treatment of illness; mean-
ing responses elicited after the use of inert or sham treatment
can be called the ‘placebo effect’ when they are desirable and
the ‘nocebo effect’ when they are undesirable.” The magnitude
of these meaning responses can be as minor as liking the outft
that the physician wears when treating you (stethoscope and lab
coat; Blumhagen, 1979), all the way to achieving the same out-
come with sham surgery (an incision with no actual surgery for
knee repair; Sihvonen et al., 2013). The color of pills is known
to have an effect even when the pills themselves are inert (i.e.,
red pills are known to create a stimulant effect, whereas blue
pills create a depressive effect [Blackwell et al., 1972; Shapira,
McClelland, Griffths, Newell, 1970]). Taking 2 inert pills can
have a larger meaning than taking only 1 inert pill (Moerman,
2000), and the name recognition of the pill can infuence its
effectiveness (i.e., familiar brand named pills are more effective
than unfamiliar named pills; Branthwaite, & Cooper, 1981). In
sports medicine, the same 10-week exercise program designed
to target aerobic improvements worked for 2 groups equally
well. However, one of the groups was told that the 10-week
program would also enhance their psychological well-being.
The group that was told the additional information showed an
improvement in both aerobic capacity (like group 1) but also
an improvement in psychological well-being (Desharnais et al.,
1993). Even in cultural anthropology, beliefs, and perceptions
have been found to infuence mortality rate. Chinese individuals
born in “unlucky” years die 7% earlier than Chinese individuals
born in “lucky” years even if they were raised in the same coun-
try (United States) with the same access to health care (Phil-
lips et al., 1993). As the authors point out, people seem to die
younger because of Chinese ideas, not Chinese genes.
Meaning in Audiology
If outcome changes can be found in the absence of treat-
ment, it is likely that there are a number of cognitive (nonau-
ditory) factors that vary in a meaningful way for people that
subsequently have an impact on their performance. A recent
consensus workshop was convened and a special issue of Ear
and Hearing was devoted to the ideas generated at that con-
ference (Pichora-Fuller et al., 2016). The authors developed
a framework for understanding the complex relationships
between nonauditory factors, for example, motivation/arousal
and task demands, that may have a direct impact on effort and
