Website Complexity: Objective versus Subjective Measures

Site complexity has been defined both as a single construct and as multi-dimension construct and operationalized in terms of objective measures or user perceptions. In this research, we distinguish between objective and subjective (perceived) site complexity and examine the relationship between the two. Objective site complexity is measured by how varied a website is; subjective site complexity...

Correlational Analysis of Objective and Subjective Measures of Cataract Quantification.

PURPOSE To evaluate whether correlations exist between objective and subjective measures of vision quality as a consequence of cataract and whether this may qualify the Objective Scatter Index as a supplementary means of cataract assessment. METHODS A prospective multicenter, cross-sectional study was conducted in 10 centers across France in patients undergoing cataract extraction surgery (le...

Subjective outcome measures of drug efficacy.

The use of subjective outcome measures for assessing drug efficacy varies according to the disease in question. Subjective outcome measures used to complement an objective outcome measure can clearly claim the status of a main outcome measure. The validation of an instrument follows an appropriate methodology that focuses on two points: the methods used for its construction are set out and its ...

Objective and subjective measures of vergence step responses

Dichoptic nonius lines are used for subjectively (psychophysically) measuring vergence states, but they have been questioned as valid indicators of vergence eye position. In a mirror-stereoscope, we presented convergent and divergent step-stimuli and estimated the vergence response with nonius lines flashed at fixed delays after the disparity step stimulus. For each delay, an adaptive psychophy...
