Question description
Assignment 2: Attentional Blink
There are many stimuli in your environment of which you are
not aware. You use attention to filter out unimportant stimuli and focus
on relevant stimuli. However, there are circumstances under which you
cannot perceive stimuli, regardless of how hard you “pay attention.” One
situation is when visual stimuli are presented in quick succession. If
the interval between the two stimuli is short enough, you do not
perceive the second stimulus. This lapse in attention is known as
attentional blink. In this assignment, you will experience the
attentional blink for yourself and will also read about practical
implications of the phenomenon.
Access the CogLab demonstrationAttentional Blink. Follow the instructions to complete the demonstration.
Read the following article:
Livesey, E. J., Harris, I. M., & Harris, J. A.
(2009). Attentional changes during implicit learning: Signal validity
protects a target stimulus from the attentional blink.Journal of Experimental Psychology: Learning, Memory, and Cognition,35(2), 408-408-422. doi:10.1037/a0014525 (ProQuest Document ID: 614494049) Retrieved from Using the experience from the CogLab
demonstration and information from the article, write a paper that
addresses the following:
Explain how the attentional blink relates to
attention. Analyze how the variation in time influences the
probability of seeing the second target letter. Explain the
circumstances under which the attentional blink can be eliminated.
In the CogLab demonstration, letters were used
as targets. The target used can influence the duration of one’s
attentional blink and whether the attentional blink even occurs.
Complete the following tasks:
Propose at least two other targets that could be used to induce the attentional blink. Predict the effect each of your suggested
targets would have on the duration of one’s attentional blink as
compared to the CogLab activity you completed. Explain the reasoning behind your predictions. Present and discuss at least three occupations
in which workers’ performance could be adversely affected by
attentional blink. Identify and explain the types of problems or
mistakes that might occur in such occupations due to the
attentional blink. Several years ago, some vehicle models came
with a heads-up display (HUD). Instead of looking down at a panel
on the dashboard, speed, distance traveled, fuel level, and time
appeared to be displayed over the hood of the car. Discuss this
design in terms of divided attention and attentional blink. Do you
think the design was a good idea?Write a 4-page paper in Word format. Apply
APA standards to citation of sources. Use the following file naming
convention: LastnameFirstInitial_M2_A2.doc.
By Wednesday, August 7, 2013, deliver your assignment to the M2: Assignment 2 Dropbox.
Assignment 2 Grading Criteria
Maximum Points
Explained the phenomenon
of attention, described how time between targets affects the
probability of seeing the second target, and analyzed how it can be
eliminated or reduced in other conditions showing understanding and
application of cognitive psychology concepts.
Applied knowledge of
cognitive psychology concepts to propose other targets appropriate for
experiment, predict their effects on attentional blink, and provide an
explanation for predictions showing understanding and application of
cognitive psychology concepts.
Identified three
occupations that could adversely be affected by attentional blink and
explained the types of problems or mistakes that might occur in such
occupations due to attentional blink showing understanding and
application of cognitive psychology concepts.
Related the concepts of divided attention and attentional blink to explain the heads-up display (HUD) design.
Wrote in a clear, concise,
and organized manner; demonstrated ethical scholarship in accurate
