Previous research has demonstrated the difficulty of reducing their frequency by means other than redesigning the task structure [Byrne, M.D., Davis, E.M., 2006. Task structure and postcompletion error in the execution of a routine procedure. Human Factors 48, 627 638].
Parents differed in opinion about the difficulty of reducing the frequency of sugar consumption at home.
Statements on diet behavior can be affected by the subjective rating of portion sizes and by the difficulty of recalling the frequency and amount of food intake.
The lack of a relationship might have been due to the difficulty of determining dominant frequencies in broad-band sounds and perhaps the small size differences of fish used in that study.
To circumvent the difficulty of documenting the frequencies of all 3 D configurations, iASeq employs a technique that can describe the major correlation patterns in the data using a few probability vectors whose values vary from 0 to 1 rather than being dichotomous (i.e., 0 or 1).
These PROs included questions with ratings of difficulty, frequency, severity, and global ratings.
The effect of frequency of difficulty initiating sleep did not vary with gender (p = 0.82, 2 df, χ2 = 0.91, model 2).
Mental health was measured by two domains: memory in terms of amount of difficulty and emotion in terms of frequency of events.
The later component, the N400, has been intensely studied with EEG where it is found to be modulated by the degree of difficulty of contextual integration, stimulus frequency, and stimulus repetition [22].
The LLFDI is an outcome survey on activity and participation that assesses physical functioning and disability in terms of frequency, limitation and difficulty in performance of life tasks [ 13, 14].
