Overview:
This article delves into the research conducted by Hill and Watanabe in 1893 on the “sensorial” and “muscular” reaction times. They aimed to determine if the difference in reaction times, previously observed with the “ordinary key” apparatus, was a result of the instrument or individual disposition.
The authors challenge Dessoir’s assertion that the difference was solely due to the type of reaction instrument. They conducted experiments using three different keys – the ordinary key, Dessoir’s finger-key, and Cattell’s lip-key. This provided diverse muscular actions for the reaction-movement.
Their findings show that the sensorial-muscular difference can be observed with different instruments, suggesting it is not merely a function of the apparatus. They also find that some individuals are better suited for reaction experiments due to their “mental disposition” or “Anlage”.
Main Parts:
- Introduction: Introduces the research question, citing Dessoir’s findings and hypothesis.
- Methodology: Details the experimental design, instruments, and participants.
- Results: Presents data in tables, highlighting differences in reaction times for various individuals and reaction keys.
- Discussion: Analyzes results and draws conclusions about the sensorial-muscular difference, challenging Dessoir’s view and emphasizing the role of individual disposition.
View on Life:
- Deterministic View: The article suggests a predisposition towards a particular type of reaction, indicating a deterministic view of individual differences. Some individuals are inherently better suited to certain types of tasks.
- Practiced Skill: The study also acknowledges the role of practice and learning, suggesting that skill and training can influence performance even with a pre-existing disposition.
Scenarios:
- Reaction Time Experiments: The article details the execution of numerous reaction time experiments, using different keys and varying attentional focus (on stimulus or movement).
- Individual Differences: The experiments reveal individual differences in reaction abilities, highlighting variations in consistency, speed, and responsiveness to different stimuli and methods.
Challenges:
- Consistent Reaction: The challenge of finding participants capable of producing consistent and accurate reaction times.
- Accurate Instrumentation: The authors acknowledge the limitations of the new chronoscope, noting a need for thorough testing and calibration.
- Individual Variation: Reconciling individual variations in reaction times and their relation to the “sensorial” or “muscular” type.
Conflict:
- Dessoir’s Hypothesis vs. Hill and Watanabe’s Findings: The central conflict lies in challenging Dessoir’s view that the sensorial-muscular difference is solely a product of the reaction instrument. Hill and Watanabe present evidence that the difference can be observed with different keys, suggesting individual disposition plays a significant role.
