Access the CogLab demonstrationAttentional Blink. Follow the instructions to complete the demonstration. http://www.cs.kent.ac.uk/people/rpg/pc52/AB_Webscript/instr.htmlRead 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 fromhttp://search.proquest.com.libproxy.edmc.edu/docview/614494049?accountid=34899Using 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?

Debate: Standardized Testing vs. Authentic AssessmentProponents of standardized testing argue that schools must be held personally accountable for the achievement of every student.  Standardized tests are the simplest and most effective tool for measuring student progress and teacher success across the nation.Opponents argue that while schools should take student achievement seriously, they should not be penalized for students who do not meet state determined achievement goals, as long as students make progress. Furthermore, standardized assessment is not an accurate reflection of teacher performance. Based on your experience in early childhood education, and additional research, choose a side in this debate and argue either for or against the use of standardized test scores to determine teacher performance. In your answer be sure to include the following: Clearly state your position. Discuss developmentally appropriate educational practices in your response. Cite research to support your answer. Avoid generalizing and instead cite specific examples (these may include personal experiences from your teaching). Suggest an alternative form of assessment that is authentic and developmentally appropriate. Cite at least two references. ORIGINAL WORK ONLY!
