If we wanted to experimentally test people's attitudes towards a person based on speech style, a well-established method we could use is:

A) the matched-guise technique.
B) a Thurstone scale.
C) a breath-testing device.
D) the bilateral earphone assembly.

Matched-Guise Technique

A research method used in sociolinguistics and social psychology to assess attitudes towards different languages, dialects, or accents by having participants react to the same speaker presenting in different guises.

Thurstone Scale

An 11-point scale with 22 items, 2 for each point. Each item has a value ranging from very unfavourable to very favourable. Respondents check the items with which they agree. Their attitude is the average scale value of these items.

Breath-Testing Device

A tool used to measure the concentration of alcohol in an individual's breath, commonly used in law enforcement to determine impairment.
