OBJECTIVE The assessment of cognitive functions of adults with attention deficit hyperactivity disorder (ADHD) comprises self-ratings of cognitive functioning (subjective assessment) as well as psychometric testing (objective neuropsychological assessment). The aim of the present study was to explore the utility of these assessment strategies in predicting neuropsychological impairments of adul...

In this article we discuss the suitability of various equipment types used to capture the user’s subjective perceptual quality evaluation for video streams with time-variant quality. We present four basic types of testing equipment (mouse, joystick, throttle and sliding bar). Since method and equipment used for testing must not influence the test results, we analyzed the requirements for the te...

This study examined male Asian international college students' perceptions of racial discrimination, subjective masculinity stress, centrality of masculine identity, and psychological distress by testing a moderated mediation model. Participants were 160 male Asian international college students from 2 large public universities. Participants' perceived racial discrimination was positively relat...

Topic area: image and video processing and analysis / image and video coding Abstract. The influences of task and scene content on a viewer's subjective opinion of compressed video quality are investigated. A group of test subjects are presented with a number of compressed video clips, with or without an initial " task " instruction. Subjective quality ratings and selected eye movement tracking...

OBJECTIVE To evaluate the effectiveness of the Semmes-Weinstein monofilament examination (SWME) for diabetic peripheral neuropathy (DPN) screening at an outpatient clinic. METHODS Eighty-two type 2 diabetic outpatients were questioned about 13 subjective symptoms and tested for deep reflexes. They were examined using two types of quantitative sensory testing: SWME (using 4.31/2 g and 5.07/10 ...

Background Mild cognitive impairment is considered as the first clinical manifestation of Alzheimer's disease (AD), when the individual exhibits below performance on standardized neuropsychological tests. However, some subjects before having a lower performance on cognitive assessments already have a subjective memory complaint. Objective A review about subjective cognitive decline, the assoc...

An objective quality estimator for either still images or video should accurately estimate the perceived quality scores of a collection of stimuli. New applications and processing techniques will introduce novel distortions that will need to be quantified in terms of perceived quality in order to confidently evaluate an objective quality estimator. The subjective testing method used to obtain t...

Extending the seminal work of von Neumann and Morgenstern (1944), Savage (1954) advanced a theory that allows decision makers to maximize expected utility based on subjective probabilities of different states when objective probabilities are unknown. Since then, an extensive theoretical and empirical literature has explored how beliefs are formed or updated and how they affect behavior (Dominit...

BACKGROUND Allodynia is a common and disabling symptom in many patients with neuropathic pain. Whereas quantification of pain mostly depends on subjective pain reports, allodynia can also be measured objectively with quantitative sensory testing. In this pilot study, we investigated the clinical relevance of quantitative sensory testing with Von Frey monofilaments in patients with allodynia as ...

BACKGROUND Laboratory testing is the single highest-volume medical activity and drives clinical decision-making across medicine. However, the overall landscape of inappropriate testing, which is thought to be dominated by repeat testing, is unclear. Systematic differences in initial vs. repeat testing, measurement criteria, and other factors would suggest new priorities for improving laboratory...
