Visual Stress Clinical Trial
Official title:
Visual Stress of the Open Urban Environment
Background and objectives: There is a general agreement that some types of urban environment
could be the source of psychological stress as opposed to natural-relaxing environment. A
number of aesthetical researches found out that the main cause for stress appearance can be
explained by the complexity and order of the environment. There are also some indications
that the stressing influence of the open environment can be measured by evaluating eye
movements, in particular saccadic movements.
The objective of this study is to characterize eye movements - mainly saccades -while
presenting visual material of different complexity and order and to evaluate the possible
relationship between eye movements and parameters of psychological and physiological stress.
Methods: The research is based on systematic gradual experiments on healthy volunteers, who
will be tested while viewing series of abstract figures and pictures of natural and urban
areas with different level of complexity and order. Each figure or picture will be showed to
subjects for 7 seconds. During the whole experimental session the investigators will
measure:
1. Saccadic and other eye movements using the magnetic scleral search coil technique. The
magnetic scleral search coil technique is the most sensitive and accurate technique
used in modern ocular motor research for measuring horizontal, vertical and torsional
eye movements. The coils are easy to apply and well tolerated over a wearing period of
up to 45 minutes per recording session.
2. Heart rate pulse will be measured using a commercial pulse-meter.
3. Aesthetical evaluation: Following each figure or picture 7 seconds presentation;
subjects will rate it in a scale from 1 (very relaxing) to 10 (very stressful).
Possible relationship between saccadic eye movements, heart rate and aesthetical rate will
be analyzed using WIN 11 SPSS and MATLAB in statistically accepted ways.
Population: A total of about 60 healthy subjects aged 18-60 years old will be recruited for
the study from students, faculty and staff of Tel Aviv University and of Meir Medical
Center.
Criteria for inclusion: Healthy subject with normal vision
Criteria for exclusion: Eye disease such as corneal or scleral abrasion or disease,
glaucoma, refractive errors greater than 2 diopters and concurrent medication with
CNS-active agents.
