Description

Activity #4: Mapping Vision Materials: Computer/Tablet with Powerpoint Stimulus Slides downloaded from Blackboard Measuring Tool (Measuring tape/Ruler/Ruler app) 2 Small Objects (to use as markers) Recording Sheet Instructions: Download the Stimulus Powerpoint slides from Blackboard and start them in presentation mode on your computer. Sit comfortably in front of your computer and look away from your computer screen. Slowly move your eyes towards your monitor. As soon as you can detect the colour of the word on the screen place your first marker in the location where your eyes are looking. Continue moving your eyes towards the monitor. As soon as you can read the word on the screen place your second marker where your eyes are looking. Once you have made both assessments, record the distance of each marker from the end of the word on the screen. Record both numbers in the table below. Please notice that there are two sizes of letters: be sure record your data under the appropriate conditions. Once you have recorded your results from all of the stimuli, calculate the 4 averages for each set of data (ie., average distance to identify colour for large letters, average distance to identify colour for small letters, average distance to read the word for large letters, and average distance to read the word for small letters. Enter the averages into the spreadsheet provided. For clarification of these instructions, be sure to consult the instructional video on Blackboard!

Next, graph your results for both the large and small letter stimuli. Calculate the average distances for the large and small letters independently. You should have 4 averages:

Average distance to ID Colour with Large Letters: ________29 inch_______________ Average distance to ID Colour with Small Letters: ________16.4 inch_______________ Average distance to Read Word with Large Letters: _______14.8 inch________________ Average distance to Read Word with Small Letters: ___________7.8 inch____________

Enter these averages into the spreadsheet provided (VisionText.xlsx) to create bar graphs of your data. The graphs that are embedded in the .xlsx file should adapt to your own input. Submit the .xlxs file for your final assignment this week!...
