Fig 1.
Relative frequency of “anxiety” and “depression” in the corpora.
Fig 2.
The severity index for “anxiety” in the psychology abstracts corpus from 1970 to 2018.
The grey bars around the linear regression line indicate the standard error estimate.
Fig 3.
Relative frequencies of selected anxiety collocates in the psychology abstracts corpus by decade.
Relative frequency is the summed repetitions of one lemma within a decade divided by the summed repetitions of all lemmas in the same decade. Larger relative frequency means higher frequency of the lemma in a particular decade.

Fig 4.
The severity index for “depression” in the psychology abstracts corpus from 1970 to 2018.
The grey bars around the linear regression line indicate the standard error estimate.
Fig 5.
Relative frequencies of selected depression collocates in the psychology abstracts corpus by decade.
Relative frequency is the summed repetitions of one lemma within a decade divided by the summed repetitions of all lemmas in the same decade. Larger relative frequency means higher frequency of the lemma in a particular decade.

The severity index for “anxiety” in the CoHA/CoCA corpus from 1970 to 2018.
The grey bars around the linear regression line indicate the standard error estimate.
Fig 7.
Relative frequencies of selected anxiety collocates in the CoHA/CoCA corpus by decade.
Relative frequency is the summed repetitions of one lemma within a decade divided by the summed repetitions of all lemmas in the same decade. Larger relative frequency means higher frequency of the lemma in a particular decade.

The grey bars around the linear regression line indicate the standard error estimate.
Fig 9.
Relative frequencies of selected depression collocates in the CoHA/CoCA corpus by decade.
Relative frequency is the summed repetitions of one lemma within a decade divided by the summed repetitions of all lemmas in the same decade. Larger relative frequency means higher frequency of the lemma in a particular decade.

Relative frequencies of selected depression collocates in the CoHA/CoCA corpus by decade.
Relative frequency is the summed repetitions of one lemma within a decade divided by the summed repetitions of all lemmas in the same decade. Larger relative frequency means higher frequency of the lemma in a particular decade.
