In a standard redundant-target task, participants make a speeded response to a target presented in either of two channels (e.g., on a visual channel and an auditory channel).
Most importantly, in the group of spider-fearful individuals, spider pictures had a strong and specific influence on even the fastest motor responses: Phobic primes entailed the largest priming effects, and phobic targets accelerated responses, both effects indicating speeded response activation by phobic images.
Science
In addition, none of the targets required a speeded response [27], [29], [30].
Science
In addition, mean reaction times were determined for speeded response trials with respect to stimulus onset.
Science
Previous electrophysiological studies investigating this issue focused on brain potentials elicited after erroneous responses, mainly in simple speeded response tasks.
Science
In the speeded response condition, participants generally made more errors and differences between stimulus sets were less pronounced.

Nevertheless, asking the participants to report expectancies while performing speeded responses makes matters more complicated.
Science
We compared speeded and delayed responses and expected only the former to modulate eGBRs, since speeded responses can only be based on fast stimulus discriminations.
Science
This being said, speeded responses in the hold condition appear to have been given at the expense of accuracy.
Science
Other recent studies investigated visual and auditory tasks without speeded responses, but also without behavioural evidence for interference between visual and auditory processing [22] [25].
Science
Furthermore, to constrain waiting strategies that may limit the validity of the stop-signal paradigm [22], subjects were required to make timed rather than speeded responses [23].

Expert writing Tips
Best practice
If "speeded response" is the correct term according to your field or professional context, double-check capitalization and punctuation before using it.
Common error
Avoid using "speeded response" in everyday language. While technically correct, it sounds unnatural. Opt for simpler alternatives like "fast response" or "quick reaction" for better clarity and flow.

Ludwig's WRAP-UP
In summary, "speeded response" refers to a rapid reaction, often within the context of scientific experiments. While not grammatically incorrect, Ludwig AI indicates that it can sound awkward and less common compared to alternatives like "fast response" or "quick reaction". Its usage is primarily concentrated in scientific literature, making it formal in register. When aiming for clarity in general writing, consider more conventional alternatives. When speaking in a formal or scientific context, "speeded response" is more than correct.

FAQs
What does "speeded response" mean in psychological research?
In psychological research, "speeded response" refers to a task or condition where participants are instructed to respond as quickly as possible to a stimulus. This is often contrasted with delayed response conditions where there is no time pressure.
What are some common alternatives to "speeded response"?
Alternatives include "fast response", "quick reaction", or "rapid response". The best choice depends on the specific nuance you want to convey.
In what contexts is "speeded response" most appropriate?
"Speeded response" is generally most appropriate in scientific or technical writing, particularly in the fields of psychology, neuroscience, and related areas where specific experimental paradigms are being discussed. Outside those fields, simpler language will likely be clearer.
Is "speeded response" grammatically incorrect?
While not strictly grammatically incorrect, "speeded response" is less common and can sound awkward to some readers. More conventional phrasing, such as "fast response" or "quick response", is often preferred. Consider also "expedited response" if you need to make it extra official.
