The phrase "attention frequency" is correct and usable in written English.
It can be used in contexts related to psychology, neuroscience, or marketing, where the focus on how often attention is directed towards a stimulus is relevant.
Example: "The study aimed to measure the attention frequency of participants when exposed to various advertising techniques."
Alternatives: "focus rate" or "attention span frequency".
Ding et al. (2006) systematically studied SSVEPs at frequencies ranging from 3 to 20 Hz, and found frequencies where SSVEPs were enhanced by attention, frequencies where SSVEPS were enhanced when the stimulus is not attended (suggesting active mechanisms of suppression) and frequencies where no effect of attention on the SSVEP was observed.
To mitigate this inevitability, Mr. Friedlander appears to pay careful attention to frequency of jokes.
The sensitivity of portfolios to beliefs is small on average, but varies significantly with investor wealth, attention, trading frequency, and confidence.
Mr. Lehman composed most of the music on the album with clinical attention to frequency and overtone: his harmonies were devised with the help of spectrum analysis and programming software.
Next we shift our attention to frequency selective channels.
TV beats the web on time spent and on focus of attention (or "frequency, reach and engagement" in marketer-speak).
We examined the use of a computerized insulin dosing algorithm to manage hyperglycemia with particular attention to frequency and conditions surrounding hypoglycemic events.
The present study examined the neural correlates of feature-specific auditory selective attention to frequency modulation (FM) and auditory motion, which engage distinct auditory cortical regions (Hart et al., 2004).
Our differential time-frequency decoding map (Figure 7C), however, revealed rather distributed effects of attention across frequencies.
The results demonstrated evidence for attention-related, feature-specific enhancement during attention to frequency-modulated targets as compared with attention to motion targets occurring within the same stimulus sequence.
