INTRODUCTION

English translation pending.

CORE DEFINITION

The think-aloud method requires participants to verbalise everything passing through their mind while completing a task. In usability testing it exposes where users search, hesitate, and misinterpret, information that silent observation misses. Cognitive psychology uses the same spoken-report method to study how people solve problems. The qualification is that concurrent verbalisation is not introspection about causes, and it imposes a cognitive load that can alter the very performance being studied.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use Usability Diagnosis: watch where users hesitate and hear why before fixing the interface. - Use Reasoning Capture: record the path someone takes through a problem to locate broken assumptions.

Anchor fast decisions

Much of skilled performance runs automatically and leaves no trace. Requiring speech forces these processes into working memory and out through language, so the researcher gains access to goals, expectations, and confusion at the moment they occur rather than reconstructing them from a final result.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Beat Frequency

The term "beat note" or "beat frequency" originates from acoustics, referring to the interference of two sound waves with similar but different frequencies. The resulting interference signal has a frequency equal to the absolute difference between the two original frequencies, hence the name. This concept is also applied in optics and electronics, where combining two signals of different frequencies yields a new signal with a frequency equal to their difference. For example, consider two sine waves with equal amplitude, no phase difference, but slightly different frequencies.
