Abstract
The purpose of the present study was to investigate the effects that time-limit and posture have
on academic test taking. This study involved participants completing a nine question multiple
choice critical thinking test. A total of 43 participants participated in the study. Participants were
randomly assigned to one of four conditions. All participants scored similarly. No significant
results were found. These results show that there are no changes that need to be made in the
academic test taking setting involving student posture and testing time-limits.
Keywords: critical-thinking, testing, posture, sitting, standing, time-limit

The Effects of Posture and Time on Test Taking
The American educational system is constantly changing, for the time being, pencil and
paper tests are standard practice. Like all forms of testing, distractions and other such obstacles
stand in the way of test takers performing at their best. Time limits of various stringency exist in
test taking. Addressing any negative effects these time constraints have on performance is
necessary in order to help students succeed in school. Classrooms are typically furnished with
student desks. Student desks are typically one solid piece; a chair attached to a desktop. The
design of the typical student desk is not very ergonomic. Any effect that posture has on testing
would not only be useful, it would be very easy to correct negative effects because of the similar
design seen in most student desks.
Whether a student has 3 hours to answer 3 essay questions, or 1 hour to take a 100
question multiple choice test, time limits exist in the world of academic test taking. When it
comes to test taking time constraints have numerous negative effects on the test takers ability to
perform at their best. Plass and Hill (1986) compared the test results of grade school children
when they were tested with a time limit, and when the students had no time limit. Students were
then tested on math problems. They found that without a time limit all the male students with
mild to high test anxiety performed significantly better than males with mild to high test anxiety
who were presented with a time limit. Interestingly, males with low test anxiety and females with
high test anxiety performed better when presented with a time limit. This research shows that the
presence or absence of a time limit can have significant effects on a student’s ability to perform
on a test.
4POSTURE AND TIME ON TESTING
Time limits have both positive and negative effects on test taking. The problem is “test
taking” is extremely vague. Referring to academic test taking begs the question of the type of
test. Goldhammer, Naumann, Stelter, Toth, Rolke, and Klieme (2014) found that the type of
questions that are asked on a test affects whether time will have a negative or positive effect.
Goldhammer et al., (2014) found that increased time spent on a reading task was negatively
correlated with scores on the task. It was also found that more time spent on a problem solving
task was positively correlated with scores. While both reading and problem solving tasks are
present in the American educational system this research shows that it is important to match
appropriate time limit with the type of test. The present study will be focusing on problem
solving type tasks; specifically critical thinking tasks. Yanchar, Slife, and Warne (2008) describe
the reasons why psychologists are constantly debating the concrete definition of critical thinking.
They came to the conclusion that critical thinking cannot be described in a simple or concrete
way.
Besides pencil and paper tests there are other typical features in the American educational
system that are just as common, but often over looked as having any effect on student
performance. Classroom furnishings are not always similar. However, there is one common
feature seen in American classrooms; student desks. Student desks are typically rigid and un-
adjustable. The design of student desks can have an effect on the posture of the user. Arpaci
(2013) took the anthropometric measurements of 240 University students and proposed that the
measurements be used to design University furniture. Not surprisingly, few similarities were
seen in anthropometric measurements across genders. The only notable similar measurement
being hip width. Designing an entire Universities' furniture based off the average anthropometric
5POSTURE AND TIME ON TESTING
measurements of it’s students would improve the ergonomics of the classrooms. The problem
with this type of intervention aside from practicality is that it does not address individual
students’ postural issues.
The only feasible way for an institution to provide individualized ergonomics in the
classroom is to allow students to control the height of their desks and chairs. Saarni, Nygard,
Rimpela, Nummi, and Kaukiainen (2007) took this simplified approach to address ergonomics in
the classroom. They supplied the students with adjustable height desk tops, and adjustable height
saddle style chairs. They compared the neck and back straightness of students using the
adjustable furniture with students in the same grade using traditional student desks. At the same
time researchers measured the height of the students’ desks after the students had adjusted them
themselves. It was discovered that the adjustable furniture increased neck and back straightness.
It was also discovered that students tended to raise the height of the adjustable desks higher than
that of the traditional desks.
Addressing student posture goes beyond the comfort aspect of ergonomic furniture.
While student comfort is important, body position has been shown to significantly affect
cognition. Kerr, Condon, and McDonald (1985) tested the effects of posture on spatial and non-
spatial memory. All subjects performed either a spatial or non-spatial memory task while seated.
Subjects then practiced the balancing task which required then to stand one foot in front of the
other. Subjects then performed the same type of memory task. Researchers found that
performance in the spatial memory task improved while balancing. These findings show that
body orientation can significantly affect cognition. Other studies show that body orientation can
have significant effects on Divergent and convergent thinking. Oppezzo and Schwartz (2014)
6POSTURE AND TIME ON TESTING
found that creativity, divergent thinking, and convergent thinking can all be significantly
improved by walking rather than siting. Three different experiments were described in this study.
The methodology in the first two experiments was essentially the same. Participants took a test
of creativity and convergent thinking in the first experiment, and a test of creativity and
divergent thinking in the second experiment. Subjects took these tests first while seated, and
again after walking on a treadmill. The third experiment had the subjects take a creativity test
while seated, and while walking. The researchers then compared the results from when they were
seated vs. walking. The only difference between this experiment and the first two experiments
was that all the walking conditions took place outside on a path. These two studies show that
body position can have significant effects on our memory and the way we think.
I hypothesize a main effect of time on the ability to think critically; having a greater
amount of time on a critical thinking test will result in higher test scores compared to the scores
when a smaller amount of time was allotted. A greater amount of time taken on a problem
solving test was positively correlated with test scores (Goldhammer et al., 2014). Time limits
have also been shown to be inversely correlated with results if the test taker has mild to severe
test anxiety (Plass & Hill, 1986). I also hypothesize a main effect of posture on the ability to
think critically; taking a critical thinking test while in a standing position will result in higher test
scores compared to sitting at a desk. There is no shortage of effects that posture has on cognition.
Standing in a balancing position has been shown to improve spatial memory (Kerr et al., 1985),
and walking rather than sitting has been shown to enhance convergent and divergent thinking
(Oppezzo & Schwartz, 2014). I believe there will be an interaction between posture and time on
critical thinking. I hypothesize that participants with a long amount of time will score highest,
7POSTURE AND TIME ON TESTING
while standing will improve test scores significantly in the short amount of time condition
compared to scores of participants that sat and took the test in a short amount of time.
Method
Participants
Most participants were recruited through an online research participation sign-up
program. A total of 43 participants participated in the study. Participants were randomly assigned
to one of four conditions. Twelve participants sat, and had a 10 minute time limit. Eleven
participants stood, and had a 10 minute time limit. Ten Participants sat, and had a 20 minute time
limit. Ten participants stood, and had a 20 minute time limit. The age range of the participants
was 11 years, from ages 18 to 29, with a mean age of 19. Sixteen participants were male
(37.2%), and 27 participants were female (62.8%). Participants were mostly Caucasian
39(90.7%). Most participants were single 42(97.7%). All participants were University students,
the primary year of the participants was freshman 30 (69.8%).
Materials
A nine question multiple choice critical thinking test was developed. Some questions
required participants to pay close attention to the way a sentence was worded and reach an
answer. For example “How many 2 cent stamps are in a dozen?” While other questions required
participants to read a paragraph and reach an answer based on the information in the paragraph
(see Appendix A). The amount of time that each participant spent on their test was manipulated.
Half of the participants were allotted 10 minutes, and the other half 20 minutes (see Appendix
B).
8POSTURE AND TIME ON TESTING
Procedure
A 2x2 between-subjects factorial design was used. Participants were randomly assigned
to one of four conditions. Sitting with a 10 minute time limit, sitting with a 20 minute time limit,
standing with a 10 minute time limit, or standing with a 20 minute time limit. Participants filled
out an informed consent and demographics document. Participants were then told to either stand
at the counter, or to sit at a desk. The participants were informed of their allotted time. When the
participants were handed the exam they were told their time had started. Once participants
completed their exam the experiment was over.
Results
A 2x2 between subjects ANOVA was used to analyze the data. There was not a
significant main effect of time limit, F (1, 39) = .55, p =.46. Participants given a 10 minute time
limit (M = 5.52, SD = 1.44) and participants given a 20 minute time limit (M = 5.85, SD = 1.53)
scored similarly. There was not a significant main effect of posture, F (1, 39) =.67, p =.42. Test
scores of participants in the standing condition (M = 5.48, S = 1.60) were not significantly
different from the test scores of participants in the sitting condition (M = 5.86, SD = 1.35). There
was no significant interaction between time and posture, F (1, 39) = .36, p =.55. Standing
participants scored similarly whether they were given 10 minutes (M = 5.18, SD = 1.47) or 20
minutes (M = 5.80, SD = 1.75). Similarly sitting participants scored similarly whether they were
given 10 minutes (M = 5.83, SD = 1.40) or 20 minutes (M = 5.90, SD = 1.37).
Discussion
9POSTURE AND TIME ON TESTING
The results of this study were not significant. The hypothesis was not supported by the
results. All subjects, regardless of condition scored similarly on the multiple-choice critical
thinking test. These results show that there is no significant effect of posture, or time, on a
person’s ability to take a critical thinking test. There was also no interaction between posture and
allotted time. Based on this data an extended amount of time allotted for a critical thinking test
does not cause an increase in scores. Likewise, standing rather than sitting while taking a critical
thinking test does not cause an increase in in scores
The results of this study are inconsistent with findings of other studies on the same topic.
Posture has been shown to have significant effects on different types of cognition such as the
ability to think creatively (Oppezzo & Schwartz, 2014). Posture has also been shown to have
significant effects on spatial memory (Kerr et al., 1985). When it comes to the effect posture has
on critical thinking the results of this study show that no such relationship exists. The current
study tested the effects of posture more one dimensionally that the two above mentioned studies
by assigning subjects to only sitting and standing conditions. However, while trying to reach
results that could be translated to a classroom setting having subjects sit or stand would be the
only relevant body positions to look at.
There was no significant effect of time found in this study. This is inconsistent with
previous research on time limits and the effects they have on academic testing. Plass et al. (1986)
found significant effects of time on testing. Specifically, they found that having a time limit will
result in lower test scores in children with mild to high test anxiety. Another study looked at time
taken on a problem solving test and found that the more time taken to do the test the better the
results were (Goldhammer et al., 2014). These two studies involved testing without a time limit.
10POSTURE AND TIME ON TESTING
Due to the nature of the current study offering participants unlimited time to complete the test
was impossible. Research on student working posture has shown that students prefer a higher
desktop (Saarni et al., 2007). However this research involved adjustable height furniture. The
current study involved a high top counter, but the counter was at a fixed height, which may have
improved the working posture of some participants, but not all.
The current study shows that there is no effect of posture on the ability to think critically.
Posture, in this case, means sitting or standing. This adds to the current literature on the effects of
posture on cognition by showing that there is no significant difference in one’s ability to think
critically while in a seated or standing position. Research on the effects that body position has on
cognition could benefit from this research because of this lack of significant results. When
developing theories in the future researchers should be able to see that critical thinking is not
effected by standing or sitting. These results cannot be applied to the class room setting because
the results of this study do not show signs that there needs to be changes in the way students are
tested. This adds to the current literature on academic test taking by showing that difference in
time limit does not matter if the difference is small, and the time limit is short to begin with. In
the broad field of research surrounding academic testing the main lesson of this study is that
consistency in the way tests are given is important. However, slight changes and
accommodations such as allowing a student to have an increased time limit, or allowing students
to stand rather than sit do not cause significant changes in test scores, and do not give
accommodated students an unfair advantage over the rest of the test takers.
Practical implications of the results of this study can be applied outside a classroom
setting. A professional setting that may require thinking critically could benefit from these
11POSTURE AND TIME ON TESTING
results. Office jobs are similar to academic classes, in that they both have fairly consistently
furnished facilities. Another similarity is that both office and classroom settings require
individuals to operate within deadlines. Employees may want more time to complete a project in
order to be sure they produce work of the highest quality. Likewise, employers may want to
allow employees more time to complete a project for the same quality related reasons. The issue
is that there is always work to be done, and efficiency is important. The results of this study
would show that if an employee is expected to complete a project that involves critical thinking,
small changes in deadlines may not have a significant effect on the quality of work.
There were some notable limitations to this study. Time limit in the current study was
shown to have no effect. This is most likely due to the relatively small difference in the amount
of time given to each group. The amount of questions may have affected the results of this study.
Nine questions is likely a relatively small amount of questions compared to most college level
exams. This small amount of questions may have affected the way in which the participants
approached the test. Another limitation involving time limit is the fact that in both conditions a
time limit was presented. Participants were not told to take all the time that they need.
Limitations were also present in sampling. The age range for the participants was very small.
The sample size itself was also small.
There are still questions that need to be answered involving the effects of posture on the
way we think. Sitting and standing are two very common body positions so it is not surprising
that there is no difference in the ability to think critically while seated or standing. Other body
positions or body movements like laying down or walking would be worth investigating.
Academic test taking is something that needs to continue to be studied to ensure quality
12POSTURE AND TIME ON TESTING
education. Student’s posture in a classroom may not have any effects on critical thinking test
scores, but there are other factors present in academic testing that may be affecting results.
Another, more drastically varying element in academic test taking is temperature. If there is an
ideal testing temperature it would be worth researching so that schools could make the effort to
ensure consistent ideal testing conditions.
