Factors which determine visual acuity
The object of this study has been the investigation of the cortical and subcortical projection of the rabbits' visual field, with particular emphasis on the magnification that certain regions of the visual field undergo in the process.

Acuity, Luminance and Monocular Deprivation in the Cat.
Hubel and Wiesel (1970) described a "critical period" in the developing visual system of the cat extending from birth through the first three to four months of life based upon the ocular dominance condition of cortical neurons in monocularly deprived (MD) cats. Monocular deprivation during this …

The architecture and acuity of critical systems thinking
… of the Architecture (first). A Structure of Acuity develops that maintains meaning where the Architecture neutralised meaning (second). A Contentless Acuity follows (third), thereby allowing the contentlessness of paradigm (in)commensurability to be discussed as an application of the Acuity …

Operant Assessment of Visual Acuity in the Profoundly Retarded
The problem. Traditional subjective visual acuity tests are not effective in testing nonverbal, profoundly retarded individuals. The present paper investigated the use of operant conditioning procedures in determining threshold crossings and compared the effectiveness of the staircase and …

Short-Term Visual Deprivation, Tactile Acuity, and Haptic Solid Shape Discrimination
<p>The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, …

Inpatient Staff Perspective on Verbal De-escalation within a High Acuity Population
… of verbal de-escalation within a high acuity population as well as the factors that make either a positive or negative impact on the effectiveness of verbal de-escalation as used in high acuity impatient settings. This phenomenological study used semi-structured interviews of 5 …

Text orienting cues: Enhancing dynamic visual acuity for targets of unknown origin
Dynamic Visual Acuity (DVA) refers to an observer's ability to resolve a critical detail in a visual target under conditions of relative motion between an observer and a target. DVA research has conventionally used visual targets originating from a single fixation point and moving in a predictable …

A Comparative Analysis of Two Low-Acuity Flow Processes in the Emergency Department
… arrival to first provider contact time for low-acuity patients during all hours, F (1, 3131) = 14.6, p = < .001</p><p> There was a significant difference in the mean arrival to departure times for all patients during all hours, F (1, 6079) = 5.8, p = .016. There was no significant difference in …

The Development And Validation Of An Acuity Tool In A Pediatric Outpatient Burn Clinic
… care to management of patients with higher acuity. In a pediatric outpatient clinic specializing in burn injuries, it became apparent that the lack of an acuity tool to measure patient complexity challenged efficient nurse staffing and patient satisfaction. In this improvement project we …

Proprioceptive acuity in patients with a torn anterior cruciate ligament following a rehabilitation programme
… on avariety of tests that measure proprioceptive acuity.Methods: Subjects (N=18, mean age 34.5yrs) diagnosed with ACLD, were tested forproprioceptive acuity prior to, and after 6- and 12-weeks of rehabilitation. Joint positionsense (JPS) using a reproduction of limb position, single leg static …

Cortico-motor adaptations and proprioceptive acuity in patients with unilateral anterior cruciate ligament deficiency
… strength (MVC) were measured. Proprioceptive acuity was assessed with a weight discrimination task. Transcranial magnetic stimulation was used to assess four indices of cortico-motor excitability and the quadriceps H-reflex was measured. Results. On the injured side in the ACL group, KOS-ADLS, …

The effects of random linear target direction in a computerized Dynamic Visual Acuity task
Research on Dynamic Visual Acuity (DVA) to date has conventionally used visual targets originating from a single fixation point and moving in a single, predictable linear direction. These procedures (presumably dictated by apparatus constraints) ensured the observer knew when and from where the …

Assessment of Proprioceptive Acuity in Patients with Stroke with Left Hemiplegia Compared to Healthy Controls
Proprioceptive information from mechanoreceptors within muscles, tendons, and skin, gives rise to kinesthesia and the sense of joint position. This information is not only crucial for bodily awareness, but it also impacts voluntary motor control, the maintenance of muscle tone and posture. Cortical …

A Study of Computer-Assisted Instruction in Aural Acuity on Seventh Grade Instrumental Music Students
Research continues in the areas of aural acuity, as intonation problems plague young musicians in school bands and orchestras. It was the purpose of this study to determine if computer-assisted instruction improved the pitch matching abilities of seventh grade instrumental music students. Students …
