Study Notes on Assessment, Instrumental Conditioning, and Learning Principles

Exam Format and Timing

  • Types of Questions: Short answers and multiple choice questions included in assessments.

  • Timing for Questions:

    • Aim: 1.5 to 2 minutes per multiple-choice question.

    • Overall estimated timing for the assessment:

    • Multiple Choice: 45 to 60 minutes

    • Written Portion: 15 to 30 minutes

  • Final Exam Duration: Scheduled for 3 hours, likely containing more questions but potentially easier ratio.

Cumulative Nature of the Final Exam

  • Current Status: The final exam, as per the syllabus, is cumulative, covering all material.

  • Potential Changes: This decision may change as per the instructor's discretion (possibly influenced by mood or external factors).

Assessment Strategy and Scoring

  • Best Score Approach:

    • Students can take three assessments, but only the two best scores will count towards the final grade.

  • Options and Decisions:

    • Previous assessments had more options, but adaptability is required.

    • Discussion on the stress of selecting answers and the impact on performance.

Multiple Choice Question Challenges

  • Types of Challenges: Students often find it difficult to identify the incorrect option in multiple-choice questions due to similarities in the answers, raising doubt and affecting timing.

  • Suggestions: Reduction in the number of similar multiple-choice options may alleviate student anxiety and improve performance.

Understanding Questions and Answers

  • Difficulty with Specific Questions: Some students felt overwhelmed when asked to recall all aspects of a topic, such as a chemotherapy study.

  • Exam Structure: Written assessments allow flexibility in scoring, permitting partial credit for incomplete answers.

Exam Review Procedures

  • Importance of reviewing assessments to understand the reasoning behind grades.

  • Sharing of specific statistics to foster transparency and understanding of test performance.

Types of Learning

Instrumental or Operant Conditioning

  • Definition: A form of associative learning where the consequences of a behavior influence its future occurrence.

  • Focus: Examines the relationship between responses and their outcomes, specifically voluntary actions (contrasted with reflexive responses).

  • Real-world Applications: Skills learned through practice in sports, arts, etc. are examples of instrumental conditioning.

Basic Principles of Instrumental Conditioning

  • Developing Behavior:

    • A behavior can be reinforced (positive consequence) or punished (negative consequence).

    • Learning from consequences is key: good consequences reinforce behavior; bad consequences reduce behavior.

Key Definitions

  • Reinforcer: A consequence that increases the probability of a behavior occurring again (e.g., receiving praise or a good grade).

  • Punisher: A consequence that decreases the probability of a behavior occurring again (e.g., receiving a reprimand).

Historical Background of Instrumental Conditioning

Edward Thorndike's Contributions

  • Puzzle Box Experiments: Developed through trials with cats demonstrating trial-and-error learning.

  • Law of Effect: States behaviors followed by satisfying outcomes are more likely to be repeated.

Components of Instrumental Conditioning

Three Major Components

  1. Response (R): The behavior being measured.

  2. Outcome (O): The result of the behavior.

  3. Stimulus (S): Contextual cues that indicate when a response will yield an outcome.

Example of a Discrete Trial Procedure

  • Experiment Setup: Cats in a puzzle box, varying rates of escaping based on learning through reinforcement and trial-and-error.

Pre-Operant Procedures vs. Discrete Trial Procedures

  • Discrete Trial Procedure: Requires a single instrumental behavior per trial; distinct completion of each trial.

  • Pre-Operant Procedures: Allow multiple instrumental behaviors within a single trial, adapting to various learning scenarios.

Modern Applications of Instrumental Conditioning

Skinner Box and Operant Conditioning

  • Description: Lab apparatus allowing observation of voluntary behaviors (e.g., lever pulling) that produce desired outcomes (e.g., food rewards).

  • Key Mechanism: Behavior modifies the environment, producing specified outcomes.

Practical Examples of Instrumental Conditioning

  • Common Everyday Behaviors: Turning a key in a car to start it; pressing buttons on a vending machine to receive snacks.

Inefficiencies and Adjustments in Assessment Methods

  • Stress management in examination environments and subsequent effects on performance; discussions about the need for adjustments in testing methods for varied learning outcomes.
