Problem: Researchers were interested in studying the effect of color (blue vs. red letters) and orientation (upright vs. inverted) on letter recognition. They found that participants recognized letters faster when the letters were upright relative to inverted. There was no difference in recognition between red and blue letters, and there was no interaction. What is the best description of the result in this experiment?
Group of answer choices
- None of the descriptions are accurate
- Main effect of letter color
- Main effect of letter orientation
- Interaction between orientation and color
