3 Prolonged work on a single task results in performance deterioration Speed-Accuracy Tradeoff (Pachella, 1974; Healy, Kole, Buck-Gengler, & Bourne, 2004) Cognitive Antidote Principle (Kole, Healy, & Bourne, 2008) –Focus of attention can be lost in a long tedious task –Interrupting the task with additional cognitive requirements could counteract task disengagement

4 Experiment Conditions Standard (quizzes interspersed throughout learning) Postponed (quizzes at end of learning) Quiz questions covered only half of learning material. Testing after a delay covered all material.

5 The Task 64 true facts about 8 categories of “plants” 8 exemplars in each category 8 Trees 8 Shrubs 8 Weeds 8 Fungi ……Etc. Exemplars were given novel names to control for prior knowledge.

6 Specific Fact Format A tree that is sacred in Hinduism is the Buttony. General Fact Format A tree that is popular in eastern religion is the Buttony.

7 Design Between-Subjects Variable Learning Condition (standard, postponed) Within-Subject Variables Quiz status (quizzed, not quizzed) Test (immediate posttest, retention test) Test Fact Format (specific, general) Block (1-8) Dependent Variable Proportion of Correct Responses

17 Conclusions  Interspersed quizzes can serve a motivational function as a cognitive antidote to boredom. Interrupting learning with quiz questions is desirable because it can enhance learner engagement.  The interspersed quizzes can effectively predict delayed test performance on particular items by individual subjects.

18 Practical Implications These findings imply that clicker questions interspersed throughout a lecture should be useful for the students to dispel their boredom and for the teachers to enable them to predict subsequent test performance.
