We cannot avoid forecasting. Everything that we do is based on what we expect the outcome to be. Some forecasting is short-term and primarily preconscious such as planning a movement while taking into consideration the positions and movements of others around you. We have been making these kinds of predictions for millions of years and we apply the same processes to skills for which we have not evolved such as driving. Continue reading
“The Decline of Comprehension-Based Silent Reading Efficiency in the United States: A Comparison of Current Data with Performance in 1960” appeared in Reading Research Quarterly in 2016. While there are endless debates about reading pedagogy, there is consensus that the best way to assess silent reading efficiency is by measuring eye movements. Continue reading
If you have any question about the influence of how we evolved on our health, I hope that the following information from The Story of the Human Body by Daniel E. Lieberman convinces you….
We make many decisions every day. There is no data for most of the decisions that we make and when there is, there is a good chance that we interpret them incorrectly. Because important decisions about health and healthcare are made based on statistics, it is important to understand relative and absolute risks and what the numbers really mean. Here is what the author has to say…. Continue reading
Scanning is used to find an object, a person, or a word. This is usually simple for most adults, but not always (such as men looking into a refrigerator). As is true for many skills that have become automatic, it is easy to overlook the complexity involved and how difficult it is to learn.
Scanning requires sequential eye movements and fixations. It requires visualizing the desired object and maintaining that image while looking at other objects. This is particularly challenging if the other objects are either distracting or similar to the object in question. When this is the case, the load on working memory increases and it becomes more difficult. If we are looking for our sneakers, that is one level of challenge. If we are looking for tomato soup amongst other soups or a phrase on a page, that is very different. It can be like singing one song while listening to another. If the eye movements are random, the fixations too brief, or if the visualized image fades, we will not succeed. Scanning requires sustained vigilance.
The inability to scan efficiently wastes time and is frustrating. The quality of scanning reflects a person’s organization. They are both disciplined, sequential, and require working memory. Academically, scanning is important when we are copying so we can find our place when looking back-and-forth. It is important when finding information, such as answers to a question in a passage that has been read. If a child needs to start to read a passage over, it will be time-consuming and they will inevitably forget what is was that they were looking for. Scanning requires the integration of top-down processing (keeping the image in working memory and filtering everything else that is seen) and bottom-up processing (directing the eyes with a goal-oriented priority). Scanning is one of the skills developed in optometric vision therapy.
