A supra-maximal stimulus has the same effect as a Blank______ stimulus.Multiple choice question.thresholdrecruitmentmaximalsubthreshold

To answer the multiple-choice question:

Understanding the Question

A supra-maximal stimulus is a stimulus that exceeds the threshold needed to elicit a response. The question asks for the type of stimulus that has an equivalent effect to a supra-maximal stimulus.

Analyzing the Options

1. Threshold Stimulus: This is the minimum intensity of a stimulus that will cause a response. It is below the supra-maximal level.
2. Recruitment Stimulus: This refers to the process of activating additional motor units in response to increasing stimulus intensity.
3. Maximal Stimulus: This is the highest intensity of a stimulus that still elicits a maximal response. It is similar but not necessarily identical to a supra-maximal stimulus.
4. Subthreshold Stimulus: This is a stimulus that is below the threshold and does not elicit a response.

Conclusion

A supra-maximal stimulus can be considered equivalent to a maximal stimulus, as both can invoke the maximum response from an organism.

Final Answer

Maximal.
