Primary outcome
The different populations, aphasic patients with and without a semantic
disorder and non-aphasic controls, are compared for the type of gestures they
use and the comprehensibility of these gestures.
Secondary outcome

Background summary
pp 6-7 Researchprotocol
When speaking, people often produce hand gestures. Some of these gestures can
convey a meaning in co-occurrence as well as in absence of speech (Beattie &
Shovelton, 2002; Krauss, Chen & Gottesman, 2000). Aphasic patients typically
are restricted in their speech production. The use of meaning laden gestures
therefore, would seem to be a good compensatory strategy. However, language and
gesture production probably are closely related processes (de Ruiter, 2000;
McNeill & Duncan, 1998). De Ruiter (2000) proposes that language and gesture
are linked in the conceptualization stage of language production, a stage which
involves semantic processing. Following this hypothesis, one would therefore
expect aphasic patients with a semantic disorder to show a deficit in
gesturing.
Study objective
The primary objective of this study is to determine whether a semantic disorder
influences the ability of aphasic patients to compensate for their speech loss
with the use of gestures. Our analysis will focus on the type of gestures that
are used and the comprehensibility of these gestures.
Study design
The study consists of two experiments. In the first experiment, participants
with and without aphasia are asked to name pictures both verbally and by means
of gesturing. These test sessions will be video recorded. To determine the
comprehensibility of the used gestures, we introduce a second experiment. In
this experiment, the video clips from the first experiment are shown to naïve
healthy speakers who are uninformed about aphasia. They have to determine what
the person on the video clip is trying to express.
Study burden and risks
There is no risk associated to participation. Patients are asked to participate
in two sessions. In both sessions we will administer several diagnostic tests,
which are also used in clinical practice. The only adaption consists of the
naming of pictures with the use of gestures (this however would also not be
uncommon to be asked in therapy practice). The actual experimental condition
consists of a perception experiment in which other participants, students from
Tilburg University, have to decide what the person was trying to convey.
