[S,F,T,P] = spectrogram(...) returns a matrix P containing the power spectral density (PSD) of each segment. For real x, P contains the one-sided modified periodogram estimate of the PSD of each segment.

Simple question: Does this mean the "standard" modified periodogram, as opposed to Welch's averaged modified periodogram method described in the pwelch documentation?

Thanks.

That depends on what you take as a "standard" modified periodogram.
Welch's great heresy was that he overlapped the modified (weighted)
periodograms that he averaged.
