Traditional neuropsychological measures of executive functioning are difficult to employ in functional imaging and clinical trial contexts and have tremendous practice effects. They also have poor sensitivity and specificity, while test-retest reliability is often not assessed in computer-based tests. The present study evaluates some psychometric properties of a new Parametric Go/No-Go (PGNG) T...

Memory for everyday events plays a central role in tasks of daily living, autobiographical memory, and planning. Event memory depends in part on segmenting ongoing activity into meaningful units. This study examined the relationship between event segmentation and memory in a lifespan sample to answer the following question: Is the ability to segment activity into meaningful events a unique pred...

Listeners lateralized a monaural signal presented against a continuous background of perfectly correlated noise (NO) or of uncorrelated noise (NU). Measures of signal detectability were also secured in separate tests. Psychometric functions (percent correct vs signal energy) were determined for each task. For a tonal signal of either low or high frequency, a listener requires only slightly grea...

This study examined some psychometric properties of the Test of Basic Auditory Capabilities (TBAC). Two experiments are described that evaluate the psychometric functions and the test-retest reliability of the tests comprising the TBAC. The psychometric functions were established for young listeners with normal hearing and the test-retest reliability was evaluated both with young listeners with...

The use of judgment-based global measures of clinical treatment effects has a long history in the regulatory approval of drugs for the treatment of dementia. This paper reviews current use of these measures, noting several practical difficulties with their implementation. Importantly, global measures have usually yielded general estimates of drug effects similar to psychometric test batteries, ...

OBJECTIVE To review the evidence base for measures of cognitive functioning frequently used within the field of pediatric psychology. METHODS From a list of 47 measures identified by the Society of Pediatric Psychology (Division 54) Evidence-Based Assessment Task Force Workgroup, 27 measures were included in the review. Measures were organized, reviewed, and evaluated according to general dom...

Companies are looking for protecting their information implementing security policies and security tool kits in order to save the information, regardless that most thefts or unauthorized access are mainly committed by Human. The social engineer (perpetrator) finds vulnerabilities in employees (victims) who manage the information within Companies. To prevent this issue, is important to identify ...

This study examined the relationship between phonemic and semantic (category) verbal fluency and cognitive status in the Wisconsin Registry for Alzheimer's Prevention (WRAP), a longitudinal cohort enriched for family history of Alzheimer's disease. Participants were 283 WRAP subjects (age 53.1[6.5] years at baseline); who had completed three waves of assessment, over ∼6 years and met psychometr...

Video quality estimation is crucial for the efficient management of video delivery services. Particularly with the advances in screen technology and content delivery networks, getting an accurate estimation of the video quality as it is actually perceived by the user, is a key factor in delivering high quality-of-experience. Psychometric scaling provides the tools to measure the impact that dif...

For five years, the Copernicus system a tool for computer-aided diagnosis of mental disorders based on data coming from psychometric tests has been developed. This tool uses a variety of classification ways for differential interprofile diagnosis. In the current version of the tool, psychometric data come from the Minnesota Multiphasic Personality Inventory (MMPI) test. In this paper, we descri...
