Question

in Anne's experiment, different groups of participants were presented with different sized groups of squares (see Figure 1). For some participants the search array was composed of 4 squares, 8 squares or 16 squares. Reaction time was measured by the computer as the time between when the array was presented on the screen and the time the participant pressed the button. Anne found that as the number of squares increased so did reaction time. She concluded that as the number of items in the array (blocks) increased so did the difficulty of the task Figure 1 How was difficulty operationally defined? the number of squares in the search array the number of blue squares with a black line in the search array how many mistakes a participant made the time it took the participant to find the red square with the black line
