- Abstract
The aim was to propose a testing procedure that
allows measuring ecological valid judgments as a tool
for selecting e.g. surface materials in the design process.
Precise measures are essential for evaluation processes for
example in design research and applied studies. Contextual
effects in form of top-down processes often lead to biases in
measures such as quality or liking judgments. We examined
contextual effects of such factors by varying specific
instructions, which were based on everyday life scenarios.
We also investigated the stability and ecological validity of
evaluations with the focus on a multisensory approach
involving vision plus touch, touch-only and vision-only
conditions. Participants evaluated the materials, for preference
in experiment 1, and for perceived material properties
(thermal conductivity, hardness and roughness) in experiment
2—either with or without specific instructions. Results
showed higher consistency in the vision plus touch condition
than in the unimodal conditions. Moreover, preferences
and perceived material properties strongly varied according
to the presence and the content of instruction (scenarios).
These results demonstrate the strong impact of top-down
processes on tactile as well as visual judgments.
