Overview:
This study dives into the fascinating question of whether improving one mental skill, like estimating areas, also improves related skills, such as estimating other shapes or sizes. I explore this through experiments, focusing on how much improvement in one skill translates to other seemingly similar skills.
Main Parts:
- Introduction: The authors define key terms like “function,” “improvement,” and “efficiency” and explain their methods of testing how training in one function affects other functions. They discuss the importance of using highly similar tasks to isolate the impact of specific training.
- Methods: The study uses three main types of experiments: training in estimating magnitudes, training in observing specific letter combinations, and training in memorization. The paper focuses on the first experiment, detailing the process of training subjects to estimate areas and then testing their abilities on related tasks.
- Results: The study reveals that improvement in a specific mental function, like estimating rectangles, does not automatically transfer to other similar functions, like estimating triangles or areas without the correction factor. The authors find that the efficiency of mental functions is highly specific to the data used in training.
- Conclusion: The study emphasizes the highly specific nature of mental functions. Training in one skill may not improve, and might even hinder, performance in other seemingly similar tasks. The authors suggest that the transfer of learning is limited to cases where the training and testing tasks share identical elements.
View on Life:
- Specificity of Mental Functions: This study highlights the importance of recognizing that mental skills are highly specialized and that training in one specific skill might not lead to widespread improvement in other areas. This reinforces the value of targeted and focused practice for developing specific mental abilities.
Scenarios:
- Tea-tester, Tobacco-buyer, Wheat-taster, Carpenter: The authors use these examples to illustrate how individuals in various professions train their senses to judge specific qualities like size, taste, or texture.
- Learning to spell, Notice forms and endings in studying foreign languages, Attend to small details: These examples are used to represent how training in observing specific features can be applied to various learning situations.
Challenges:
- Finding the starting point for measuring improvement: It’s difficult to pinpoint the exact point where training begins to affect performance, as the initial trials are not representative of the full impact of training.
- Identifying the extent to which improvements transfer: Determining whether the transfer of learning is due to shared elements or a mysterious “transfer of practice” remains a challenge.
- Determining if judgments of nearly equal magnitudes are acts of a single function: The authors investigate whether judgments of similar magnitudes are part of a single function or represent distinct functions, potentially leading to independent abilities.
Conflict:
- Generalizing mental function improvement: The main conflict is between the commonly held belief that improving one mental skill can broadly enhance other skills, and the study’s findings that improvements are often confined to the specific skill trained.
- Overcoming the conflict: The authors overcome this conflict by demonstrating the limited transfer of learning, emphasizing the need to consider the specific elements involved in different mental tasks.
Plot:
- Story arc: The study begins with the premise that training in one mental function may improve related functions. The authors conduct a series of experiments to test this hypothesis. Through analysis of the results, they demonstrate that improvement in one function often does not transfer to other functions, even when those functions are seemingly similar.
- Key milestones:
- Defining terms like “function,” “improvement,” and “efficiency”
- Describing the methods of testing for transfer of learning
- Presenting the results of the experiment on estimating areas
- Drawing conclusions about the specific nature of mental functions
Point of View:
- Third person: The study is presented from a third-person perspective, focusing on the authors’ research methods and findings.
- Objective: The authors present their findings in an objective and scientific manner, relying on experimental data and statistical analysis to support their conclusions.
How It’s Written:
- Formal and scientific: The text uses precise language and a formal writing style, characteristic of scientific research papers.
- Example: “The efficiency or ‘function a’ increases with great rapidity during the first score or so of trials, so that the average error of even the first twenty estimates made is below that of the first ten, and that again is below that of the first five.”
Tone:
- Objective and analytical: The tone is neutral and focused on presenting factual information and analysis, without any subjective interpretations.
Life choices:
- Choosing a specific focus: The authors choose to focus on specific mental functions, recognizing the limitations of broad generalizations about mental abilities.
- Choosing research methods: They select methods that are rigorous and allow for quantitative interpretations of the data.
Lessons:
- Practice makes perfect but not always transferable: The study emphasizes the importance of targeted practice for developing specific skills. General improvements in mental abilities might not necessarily occur from training in a single skill.
- Focus on the details: Recognizing the specific nature of mental functions highlights the importance of considering the details of any given task.
- Embrace scientific inquiry: This study exemplifies the value of scientific inquiry and the use of rigorous methods to uncover insights into the complexities of the human mind.
Characters:
- E. L. Thorndike & R. S. Woodworth: The authors of the study, both leading psychologists of their time, who collaborated to conduct this groundbreaking research.
Themes:
- Specificity of mental functions: The study underscores the idea that mental skills are highly specialized, and improving one skill may not lead to general improvements.
- The power of focused practice: The study emphasizes the importance of focused and targeted practice for developing specific mental abilities.
- Importance of scientific rigor: The research methodology highlights the importance of using rigorous methods to study complex phenomena.
Principles:
- Specificity of learning: Learning is highly specific to the training conditions and may not transfer readily to other contexts.

Ideas:
- Mental functions are highly specific: The authors challenge the idea that mental functions are general and broad, emphasizing their specific nature and the limited transfer of learning.
Facts and Findings:
- Improvement in a specific function rarely transfers to other functions.
- Efficiency of mental functions is highly specific to the data used in training.
- Judgments of nearly equal magnitudes may represent distinct functions, not a single function.
