Attentional Blink
INTRODUCTION
The Attentional Blink Experiment aims to determine the capability of an individual to recognize both the targets given that he or she is subjected to rapidly changing stimuli. Moreover, the theory states that after the detection of the first target in a rapid stream of visual stimuli, the second target is missed (Niewenstain, Potter, & Theeuwes, 2009). Hence, the experiment means to prove whether attentional blink is present in the experiment and if the theory is correct.
Furthermore, the suggested hypothesis for this experiment is that the higher separation of the two targets with each other will increase the probability of discriminating and reporting the second target with respect to the first. In addition, the experiment was conducted inside the ergonomics laboratory at the Science and Technology research building on February 5, 2013 using the Wadsworth Coglab program application. It was done at only one site to ensure the consistency of the environment. Also, each test consisted of 100 trials.
I. PROBLEM STATEMENT
Attentional blink is present between targets of short separation.
II. OBJECTIVES
1. Aims to confirm the presence of attention blink in the different subjects. 2. Aims to show that the percentage reported for the 2nd target increases as the separation of the two targets increases through the use of statistical analysis. 3. To identify improvements for the report of the second target in the stimulus presentation, assuming the theory is correct.
III. METHODOLOGY
A. Selection of Subjects
The minimum required subjects was fifteen subjects which consists of the students of the present Ergcog2 laboratory class, and they were asked to answer the attention blink experiment honestly. The group decided to add additional of 10 subjects outside of DLSU with the same conditions given to the first fifteen subjects in the class. This was done for the reason that more data leads to more consistent and
