Key Terms to Review (20)
Anders Ericsson: Anders Ericsson is a prominent psychologist known for his research on expertise and skill acquisition, particularly the concept of deliberate practice. His work has significantly contributed to understanding how individuals can achieve high levels of performance in various fields, emphasizing that sustained, focused practice over time is essential for mastering complex skills.
Associative stage: The associative stage is a phase in skill acquisition where learners refine their performance and begin to make connections between actions and outcomes. During this stage, individuals practice and adjust their skills based on feedback, leading to increased consistency and coordination. It is characterized by the transition from early, trial-and-error learning to more systematic and efficient performance.
Attention: Attention is the cognitive process of selectively concentrating on specific information while ignoring other stimuli, allowing individuals to prioritize certain aspects of their environment. This selective focus is crucial for effective processing of information, decision-making, and memory formation, playing a significant role in various cognitive functions.
Autonomous stage: The autonomous stage refers to the final phase of skill acquisition, where an individual can perform a task with little to no conscious effort or attention. At this point, skills are well-practiced and can be executed automatically, allowing the individual to focus on other aspects of the activity or environment. This stage signifies a high level of proficiency, where performance becomes fluid and consistent, often leading to expert-level capabilities.
Bernstein's Degrees of Freedom: Bernstein's degrees of freedom refers to a concept in motor control that emphasizes the flexibility and adaptability of the body when acquiring new skills. This idea suggests that as individuals become more skilled, they learn to utilize their body's various degrees of freedom more efficiently, leading to smoother and more precise movements. Understanding these degrees allows learners to optimize their performance and develop expertise by coordinating muscle activity in a more effective way.
Choking under pressure: Choking under pressure refers to the phenomenon where individuals perform poorly in high-stakes situations due to anxiety or stress, despite having the necessary skills or expertise. This performance decline often occurs when the individual overthinks their actions or becomes overly self-conscious, leading to mistakes and subpar results. It highlights the impact of emotional and cognitive factors on skill execution, especially in competitive environments.
Chunking: Chunking is a cognitive strategy that involves grouping individual pieces of information into larger, more manageable units or 'chunks' to enhance memory retention and recall. By organizing information into meaningful clusters, chunking facilitates better encoding and retrieval processes, leading to improved performance in tasks requiring memory.
Cognitive stage: The cognitive stage refers to the initial phase of skill acquisition where individuals rely heavily on conscious thought and deliberate practice to learn a new skill. During this stage, learners actively engage in problem-solving and understanding the rules and strategies associated with the skill, leading to a gradual shift toward more automatic performance as they progress.
Deliberate practice: Deliberate practice is a structured, intentional approach to skill development that focuses on improving performance through specific, goal-oriented activities. It differs from mere repetition as it involves feedback, self-reflection, and gradually increasing the difficulty of tasks to ensure continued growth. This type of practice is essential for achieving expertise in various domains, as it emphasizes the importance of not just practicing, but practicing effectively.
Domain-specific expertise: Domain-specific expertise refers to a deep, specialized knowledge and skill set that individuals acquire in a particular field or area of study. This type of expertise is characterized by the ability to solve problems and make decisions that are unique to that domain, often leading to superior performance compared to those with more general knowledge. Individuals with domain-specific expertise not only understand the core principles of their field but also possess nuanced insights that allow them to excel in practical applications.
Expertise metrics: Expertise metrics are measurable indicators used to evaluate the level of skill and knowledge an individual possesses in a specific domain or field. These metrics can assess performance, proficiency, and progress during the process of skill acquisition, helping to identify areas for improvement and guide training efforts.
Fitts and Posner Model: The Fitts and Posner Model describes the three stages of skill acquisition, illustrating how learners progress from novice to expert. This model highlights the cognitive, associative, and autonomous phases of learning, which together provide a framework for understanding how individuals develop expertise in a particular skill or task over time.
General intelligence: General intelligence refers to the overall cognitive ability of an individual, encompassing a range of mental capabilities such as reasoning, problem-solving, learning, and understanding complex ideas. This concept is often associated with the idea of a single factor that influences performance across various cognitive tasks. General intelligence plays a crucial role in skill acquisition and expertise, as well as in the development and functioning of artificial intelligence systems.
Implicit learning: Implicit learning refers to the process of acquiring knowledge or skills unconsciously, without the learner being fully aware of what they are learning. This type of learning often occurs through exposure and practice rather than through explicit instruction, making it a crucial component in the development of expertise and skill acquisition. Implicit learning allows individuals to absorb complex information and patterns in their environment, which can lead to improved performance in various tasks over time.
John R. Anderson: John R. Anderson is a prominent cognitive psychologist known for his work in cognitive modeling and skill acquisition. He developed the ACT-R (Adaptive Control of Thought-Rational) framework, which aims to simulate human thought processes and understand how knowledge is represented and used in the brain. His research bridges the gap between theoretical cognitive psychology and practical applications, contributing significantly to our understanding of how expertise is developed and how cognitive processes can be modeled.
Memory: Memory is the cognitive process of encoding, storing, and retrieving information over time. It plays a vital role in learning and influences how experiences shape our thoughts and behaviors. This process encompasses various types, such as short-term and long-term memory, and is crucial for understanding how knowledge is acquired, maintained, and utilized in everyday life.
Mental Imagery: Mental imagery refers to the ability to create and manipulate images in one's mind without direct sensory input. This cognitive process is integral to various mental activities, including problem-solving, creativity, and skill acquisition. It allows individuals to visualize scenarios, objects, or actions, enhancing understanding and facilitating innovative thinking.

This approach is often used to measure expertise and skill acquisition, allowing for a more holistic understanding of an individual’s capabilities beyond traditional testing methods.
The Expert Paradox: The expert paradox refers to the phenomenon where individuals who achieve a high level of expertise in a certain area may find it difficult to explain their knowledge and skills to novices. This occurs because experts often possess an implicit understanding of their field, making it challenging to break down complex concepts into simpler terms that beginners can grasp. This paradox highlights the gap between expert intuition and novice comprehension, impacting the effectiveness of teaching and learning processes.
Transfer of Learning: Transfer of learning refers to the process by which knowledge or skills acquired in one context are applied to another context. This concept is crucial in understanding how individuals can use their expertise and learned abilities in different situations, enhancing the acquisition of new skills and competencies. The degree and direction of transfer can vary greatly, influenced by factors such as the similarity between tasks and the depth of understanding.
