� The scientific revolution (1473-1860)
The first thing to notice is that the scientific revolution and the emergence of Psychology as a science did not happen over night. This revolution occurred over a time period of over 200 years. Here are the main developments which led to the scientific revolution and the emergence of psychology:
� The realisation that the Earth did not form the centre of universe� Copernicus & Galilei – heliocentric model
� Many things on Earth can be understood as machines� Descartes – mechanistic view & dualism
� Many movements on Earth and in the universe can be described with a mathematical
equations� Newton – Law of physics
� Scientific method� Bacon – interaction theory and observations, falsifications & replications� Comte - Positivism
� The emergence of Psychology� Darwin� Kant� Establishment of Psychophysics� Development of statistics
What is science? Text on slides
� Choose a font style that your audience can
read from a distance
+ Helvetica
+ Arial
- Times
- Narrow Arial
� Choose a font colour
� Dark blue on light yellow preferred over black
and white
� Choose a font size that your audience can read
from a distance
� Big enough to be seen by the audience!
� Try to never go smaller than 18-point
� Labels and captions should never be smaller
than 14-point – but bigger is better

Animations - Don‘t overdo it!
‘Name given to a series of discoveries in the 17th
century, involving Galilei, Descartes and Newton,
that enhanced the status of science in society’
Three key developments1) The realisation that the Earth did not form the centre of
universe
2) Many things on Earth can be understood as machines
3) Many movements on Earth and in the universe can be
described with a few relatively simple mathematical
equations → Law of physics

General tips for good presentations
� Gestures = visual reinforcement of the words
� Open

Many types of graphs!
� Bar graphs showing frequencies
� Bar graphs showing means
� Bar graphs with error bars
� Bar graphs without error bars
� Histogramms, Line Charts, Pie Charts
Line graph or bar graph?
� When intermediate values of the independent variable are possible...
� Use a line graphE.g. when your independent variable shows points in time
� When no possible intermediates between independent variables are possible...
� Use a bar graphE.g. when your independent variable is gender

Error bars or no error bars?
� When you are showing means of your dependent variable in your graph...
� Add error barsE.g. when your dependent variable is average number of cigarettes smoked per week.
� When you are showing frequencies (number of people)...
� Do not add error barsE.g., number of males and females studying psychology.
� Why?
Start making a proper graph...
� Bar graph or line graph?
� Error bars?
What to select?How to turn it into a graph?
This is the graph you should get To add error bars...� Click once on the chart to select the whole thing
� (make sure you don't click on the inner part of the
chart because that will select just the axes and bars).

To add error bars... Your graph now looks like this:
APA-style
� Greyscale – no colour!
� No gridlines
� Don’t forget to label your axes
� Don’t forget to give your graph a figure legend
(this you simply do in Word – not in Excel)
Greyscale & gridlines
� Click on graph to select it (whole graph).
� Removing gridlines:
� Simply click on the
gridlines to select them
and then click on delete
Labelling the axes�Click on graph to select it (whole graph).
Y-axis
X-axis
Tadaaaaa!!

The good news...
�Creating other graphs works in a very similar
manner
� Try some different versions when you get home today!
Thank you for your attention!
