Experimental Design

This study was a within-subject manipulation as all the participants had to respond to word and nonword terms. Independent variable- the catergory of word type (valid word or nonword?) Dependent variable- reaction time(in milliseconds) and accuracy(correct or incorrect)?


Participants had to log on to___ to see the instructions. Participants had the choice of using a computer or tablet to complete the experiment. They were provided with specific details to which ever device they used to complete the experiment. Participants were instructed to begin the experiment but before they begun, they needed to make sure they saw a rectangle below on the page. On each trial, a fixation point appeared on the screen followed by either an English word or by a nonword. Participants had to respond as quickly and accurately to indicate whether the stimulus was a word or nonword. At the end of the experiment, participants had the choice to save their data to a set global data. Participants were presented a debriefing, their data, the group data and as well the global data on a new web page after the experiment ended.

For this study, there was 96 trials. Each took about a second or two for participants to respond.

Researchers plan to conduct an ANOVA statistical test to determine whether the three conditions were statistically


During the study, participants were slightly faster when the two stimuli were associated than when they were not associated. The responses to words were faster than responses to nonwords. Overall, there was an effect of the manipulation for this study. The mean reaction times varied amongst the three groups. The Associated condition of this study had an average reaction time (RT) of 734.342 ms (225.451 ms). The Unassociated condition of this study had an average RT of 747.489 ms (225.645 ms). The Nonwords condition of this study had average RT of 879.132 ms (250.201 ms). Figure 1 displays the mean reaction times and the differences between the reaction times in three conditions. After conducting the ANOVA statistically test, there was a significant difference between words and nonwords in means of RT. There was not a significant difference between the RT of associated and unrelated words.
