Please answer the following two questions that pertain to Lecture 04 and Lecture 05

  1. Explain the concept of preattentive processing. Be thorough: describe both what is happening from a physiological level as well as its consequence of our interpretation. Give an abstract example of where preattentive processing might be leveraged to improve a visualization.

  2. Stevens [1946] decomposes scales of measurements into four types while Munzner [2014] describes three attribute types. Explain both sets of types and describe which operations are relevant for each. State a mapping of Stevens’ categorization into Munzner’s.

Grading

Submit your quiz in a folder called quizzes in your git repo. Within this folder create a file Q01.txt that has your answers.

For each question, I’m expecting an answer of 150 words or less. Aim to answer each question in a single paragraph.

I plan to grade your answer on a scale of 0-5, where 5 indicates that you completely answered all portions of the question. Thus, you will receive a score of 0-10 for this quiz. This score will be scaled to the total value of this quiz for your final grade (1%).
