Furthermore, reading ability may be considerably limited by a hemianopsia or a larger defect of the horizontal visual field, especially to the right side. Pronounced visual field defects render the exploration of the environment difficult, with corresponding consequences for daily work procedures. Visual field defects represent a serious handicap for the affected patients. The requirement to explore the matrix on a row-by-row or column-by-column basis permits testing of the ability to shift the required search strategy, which can be impaired, for example, in the case of frontal brain damage. One reaction key is used for the answer ""present"" and another for the answer ""not present"". In this task, a matrix-like arrangement of 5 x 5 stimuli is used, the aim being to detect whether this arrangement includes a critical stimulus or not. Equally diverse are the causes of a deficit in exploring the environment after brain damage, which in many cases presents an obvious handicap in daily life. It is a complex process for which the intention and prior knowledge of the individual, the ability to plan ahead, an unrestricted visual field, the ability to shift visual attentional focus, and unimpaired eye movements are important. The exploration of the visual environment is one of the most basic abilities subserving the safe movement in space, the search for an object, when regarding an object or picture, or in monitoring and controlling a traffic situation. The task is administered under two conditions: a "gap" and an "overlap" condition. The subject should respond as quickly as possible by pressing the key as soon as this critical stimulus appears. A critical stimulus appears centrally at irregular intervals. Either a critical or a neutral stimulus is presented to the left or right of a fixation stimulus (an "S" lying on its side) in pseudorandom sequence. In this task, the latency of saccadic eye movement to the left or to the right is assessed in a reaction task. In rehabilitation a deficit in saccadic eye movements can render compensation training of a visual field defect considerably more difficult. Impaired eye movement can represent a major handicap in road traffic and may result in impaired reading ability, especially when there is a right-sided manifestation. This is a central function, on the basis of which we explore our surroundings and are able to orient ourselves in a given situation. Roots may be growing into the cable buried in your yard.One of the most efficient forms of focusing is to look at something, that is, to change the direction of gaze and fixating on relevant information in the environment. Speed may be slow because you’re using the internet at peak times, or your router may be outdated.
You may even see disclaimers like “wireless speeds may vary” because Wi-Fi speeds are always inconsistent no matter what provider you choose-it’s just how Wi-Fi works.įor example, there may be issues with the provider’s service area, like faulty connections somewhere within the neighborhood. Internet providers will state “up to” when advertising maximum speeds because many variables can prevent you from hitting that top speed.
What you see on the speed test is simply where your internet speeds are currently. Most of the time, your internet speeds will fluctuate within a small range of that max speed. The speeds promised by your internet plan are the max speeds you can expect. You likely won’t ever see the maximum speed advertised by your provider in the speed test, but your speed test results should come close.
Why doesn’t my internet speed match my plan?
