Questions & explanations
1. What is sensory preconditioning?
Sensory preconditioning is when two neutral stimuli are paired together before either is linked to a meaningful event. Later, when one stimulus is paired with a reward or punishment, the other also gains the same power even though it was never directly paired. For example, if a tone and a light are presented together many times, then the tone is paired with food, the light alone will also cause salivation. This shows that the two neutral stimuli became associated with each other first. The second neutral stimulus 'borrows' the meaning from the first without direct training. Occasion setting is different: it tells the organism when a response will work, not just what to expect. In occasion setting, a cue signals that another cue will be followed by a reward or punishment.
2. Compare augmented reality (AR) with virtual reality (VR) in terms of managing germane cognitive load during a repair task.
In AR, digital instructions are overlaid on the real object, so the learner does not have to switch attention between a manual and the equipment. This reduces extraneous load and frees mental resources for understanding the steps. In VR, the entire environment is simulated, which may require more mental effort to transfer skills to the real world. However, VR can allow safe practice of dangerous repairs, encouraging deeper processing of safety procedures. For germane load, AR may better support immediate application because the learner works directly with the actual object. VR, on the other hand, can promote reflection by pausing the scenario and prompting analysis. Both can be effective if they focus the learner's attention on the key relationships.
3. How does the matching law apply to choices between delayed rewards? For example, if one option gives a small reward now and another gives a larger reward later?
The matching law can be extended to include delay by saying that the proportion of choices matches the 'subjective value' of each option. Subjective value is the actual reward divided by the delay (or some function). So the larger delayed reward may have a smaller subjective value than the smaller immediate reward. The matching law then predicts that the animal will choose the option with the higher subjective value more often. For example, if a small immediate reward has subjective value 10 and a large delayed reward has subjective value 5, the animal will choose the immediate one about twice as often. This helps explain why delay discounting leads to impulsive choices. The matching law still works, but we have to consider how delay reduces value.
4. Compare how learning a new programming language imposes cognitive load on a novice versus an expert programmer.
A novice has no existing mental model for programming, so every syntax element and concept is new, causing high intrinsic load. They must hold many separate pieces in working memory, like variable types and loops. An expert, however, already has schemas for general programming constructs. They only need to learn the specific syntax differences, which adds less load. For example, an expert can quickly recognize a for-loop structure even if the syntax is slightly different, while a novice has to understand the loop concept from scratch. Thus, experts experience lower intrinsic load and can focus on deeper aspects like efficiency. Instruction for novices should break down syntax step by step, while experts can handle more complex examples.
5. What is behavioral contrast? Give an example.
Behavioral contrast happens when a change in one situation causes behavior in another situation to change in the opposite direction. For example, imagine a pigeon pecks a key for food on a schedule. If the schedule is made worse (less food), the pigeon might peck more on another key that still gives good food. So pecking on the good key increases when the other key gets worse. This is called contrast because the change in one condition contrasts with the change in behavior in the other. It shows that animals compare conditions. Behavioral contrast is important for understanding how expectations affect behavior. It can also happen in real life, like when a worker tries harder at an easy task after a hard task is introduced.
6. How does occasion setting differ from simple Pavlovian conditioning?
In simple Pavlovian conditioning, a cue directly predicts a reward or punishment. For example, a light predicts food. In occasion setting, a separate cue tells the organism when a different cue will work. For instance, a tone might signal that a light now predicts food, but if the tone is off, the light does not predict food. So the tone 'sets the occasion' for the light to be useful. This is like a context or 'turn signal' that turns the meaning of another cue on or off. Occasion setting is more flexible and allows the organism to adjust to changing conditions. Simple conditioning is just one signal for one outcome. Occasion setting uses two signals: one that says 'pay attention' and one that carries the message.
7. Compare a need-supportive approach to a controlling approach in a workplace setting.
In a need-supportive workplace, managers offer choices, explain reasons, and encourage employee input. They provide constructive feedback and recognize effort, supporting competence. They also foster team spirit and respectful relationships, supporting relatedness. In contrast, a controlling approach uses pressure, threats, and strict rules. Managers give orders without explanation and punish mistakes. Employees lose autonomy and feel disengaged. Research shows need-supportive workplaces lead to higher job satisfaction, creativity, and lower turnover. Controlling approaches may produce short-term obedience but harm long-term motivation. The supportive approach respects employees' needs and yields better outcomes.
8. Compare the effectiveness of individual questioning versus group questioning for reaching Bloom's higher levels.
Individual questioning allows the teacher to push a single student's thinking to high levels like evaluate or create. For example, asking one student 'What alternative solution could you propose?' forces that student to create. However, group questioning, like in cooperative learning, lets multiple students think together. In groups, students can discuss and build on each other's ideas, which often leads to deeper understanding. Group questioning is especially effective for analyze and evaluate because students share different perspectives. But quiet students may not participate. Individual questioning ensures every student is challenged, but it takes more time. A mix of both is best to reach all learners.
9. What is scaffolding in instruction?
Scaffolding means giving students temporary support to help them learn new concepts or skills. Think of it like building a scaffold next to a wall; workers use it until the wall is strong enough to stand alone. In class, scaffolding can be step-by-step guides, hints, or worked examples. The teacher slowly removes support as students become more able to work on their own. For instance, when first teaching a math problem, the teacher might solve a similar problem together with the class. Later, students try on their own with fewer hints. This matches Bloom's taxonomy because easier tasks (remembering, understanding) need less scaffolding, while harder tasks (evaluating, creating) may need more support.
10. Explain behavioral contrast using the example of a child's chores. How might a parent unintentionally create it?
Suppose a child gets praise for cleaning their room every time. Then the parent stops praising for room cleaning but still praises for washing dishes. The child might start cleaning the dishes more often and the room less. This is behavioral contrast: the decrease in praise for room cleaning causes an increase in dish washing. The parent unintentionally made dish washing more valuable by contrast. If the parent then praises room cleaning again, dish washing might drop. This shows how changing one situation affects another. Parents can see contrast when children shift effort to tasks that get more attention. Understanding contrast helps parents give balanced attention to avoid unwanted shifts.
11. Compare the use of simulations for application versus digital quizzes for recall in terms of learning outcomes.
Digital quizzes for recall (like Quizlet) help students memorize facts quickly. They are efficient for lower Bloom's levels but do not develop deep understanding. Simulations for application (like PhET interactive science labs) let students use concepts in realistic scenarios, which builds stronger connections and problem-solving skills. However, simulations take more time and require guidance. Quizzes give immediate right/wrong feedback, while simulations offer exploration with delayed feedback. Both are useful: recall quizzes prepare the knowledge base, and simulations help apply it. Ideally, teachers combine them: first use quizzes for basic facts, then simulations for deeper application.
12. Give a scenario where a teacher uses scaffolding to help students move from 'understand' to 'analyze' a historical event.
A teacher wants students to analyze the causes of a war, not just understand the timeline. First, she gives a timeline of events (scaffold). Students work in pairs to sort the events into categories: political, economic, social. This is understanding because they group information. Then she provides a cause-effect graphic organizer with guiding questions like 'What event directly led to the declaration of war?' This is analysis because students identify relationships. She gradually removes the organizer and asks students to write a paragraph explaining two main causes. By providing these tools step by step, students successfully move from knowing facts to breaking down causes and effects.
