Hypothesis

Experiment #1 - Effect of the Font Size of a Reading Piece on the Idea Memory Percentage of a Middle-Aged Reader
If the font size of a reading piece is changed, then I hypothesize that the idea memory percentage will be higher with the 13 point font size because, as determined by my research, the 13 point font size is not too big and not too small, which is what is needed for readers of this age group in order to possibly help with memory.

Experiment #2 - Effect of the Type of Font (Sans Serif Versus Serif) of a Reading Piece on the Idea Memory Percentage of a Middle-Aged Reader
If the type of font of a reading piece is changed, then I hypothesize that the idea memory percentage will be higher with a serif font because this type of font has characteristics such as an extra stroke found on the main verticals of the letters that will help them flow from one to another for easy reading, which will help memory.

Experiment #3 - Effect of the Font Colour of a Reading Piece on the Idea Memory Percentage of a Middle-Aged Reader
If the font colour of a reading piece is changed, then I hypothesize that the idea memory percentage will be higher with a black font colour because there is high contrast between the colour and the background white paper, and the colour itself is not one with short wavelengths, which increase readability and may affect memory.

Experiment #4 - Effect of the Column Width of a Reading Piece on the Idea Memory Percentage of a Middle-Aged Reader
If the column width of a reading piece is changed, then I hypothesize that the idea memory percentage will be higher with a four inch column width because there is a formula used to determine the precise column width based on the font size, which is 12. Since the supposed precise column width is used, this may increase readability. Therefore, the memory of a reader may be affected by it.
