  • Cognitive ability

    Cognitive ability is used to evaluate people for a whole lot of reasons - driving and employment are but two of many.

    What is "cognitive ability"?

    http://en.wikipedia.org/wiki/Cognition

    How is it tested?

    https://www.google.com.au/?gws_rd=ss...nitive+ability

    Should or can it be used in evaluation of the potential employee or candidate for advancement/promotion?

    Does it apply in everyday life?

    In the shop?

    At work?

    What if you cognitive ability is at or too low for:

    Driving?

    Machining?

    At home

    At work?

    What do or can you do to retain or improve it?

    What are some effects of too low a level of cognitive ability - and what do you do about it?

    Cognition can be improved but it is an interesting problem to work with. The first problem is to recognize cognitive deficiency and to assess any significance it may have. I don't see how the "patient" can recognize this in themselves reliably, especially if they are truly deficient in some way. Few lay people have the ability to measure cognitive performance or even know what the units of measure are to even enumerate the degree of deficiency. Then there are metrics - you can't improve what you can't measure. That is a very specialized field and is 100% subjective based on years of data collection and reduction. The single greatest impediment is there's only one you and only one me, etc. Finding our fit in the data to establish a baseline should involve experts. And that brings us to the beginning. This journey needs to start with some self-evaluation and consideration any clues one may have that this may be an issue in their life. The simple answer to that question is "I don't know". There is only one next step - consult an expert and be honest as to what you are aware of and why you think this needs further evaluation.

    As a general practice there are brain training exercises that can be practiced regardless of one's cognition, and these will include some means of measuring any change.

        I believe to be the most important line in Tiffers Wiki link;

        Cognitive processes use existing knowledge and generate new knowledge.

          There may be a whole suite of tests that apply to a great many situations - interviews for jobs or promotions are but two of many.

          Every time I sense that I may not be up to doing what I want or need to do - including distractions etc.,- I check some of my critical reactions - going to the shop when I am tired or distracted or "just not with it" are two of several cases that I limited cognitive assessments with.

          My next task is to try to evaluate the degree of risk and then apply a "loading" depending on circumstances. Once a pre-determined level of risk is approaching or has arrived I just walk away from the risk area or activity until the risk has subsided to an acceptable level.

          This applies to a lot of stuff in the house or the shop.

          It very much applies to driving the car.

          I have to have my renal stents changed every 5 months - "Day Ward" - under anaesthesia. I do not drive for at least 2 days after and after that I check myself progressively and do no go past each stage until I've passed it. It can take another 2 to 4 days before I am back to normal.

          Cognitive testing can support or utterly destroy statements made in CV's - so be careful.

          House-hold and/or family or similar stresses can reduce cognitive ability as well.

            After a serious closed head injury 20 years ago, I was aware that my thinking processes were not quite right. I finally decided that my measure or "wellness" was going to be the windows computer game "Freecell". I found that my ability to win was near zero. Every day, I played Freecell. It took several months to get back to winning every game.

            And then there is this:

            Amazing how many of our "leaders" appear to fit in here.

              There's POCD, postoperative cognitive dysfunction.

              That's what happened to me after relativey minor hernia surgery. At the time of surgery I was installing a set of upper kitchen cabinets. Because of the hernia progress stopped on the kitchen. After a few weeks of recovery I was given the go ahead with the caution of "let pain be your limiter" as to lifting, etc.
              I was feeling good and revisited the project only to find the simplest little problems seemed insurmountable. Not having a clue what was going on I put the project on hold for a month or so. After that period the problems that had completely stumped me seemed trivial.

              Apparently, POCD can be related to how invasive the surgery is and also age related. An elderly friend had to be put in a care facility for several months before she recovered enough to live alone again. In her case there were questions whether she would ever completely recover, which she did.

                Interesting test. That is a form of formulaic problem solving - a form that includes chess, for example. Solving more abstract problems where one has to analyze related data to form a prediction is another. A non-human, non-trivial example is https://www.youtube.com/watch?v=uNHPh8TEAXM

                    Good comment.

                    POCD is what affects me after an operation and anaesthesia - and it is largely "age-related".

                    I am 78.

                    What also affects me is the difference in the anaesthetic/s used by each anaesthetist - I've always recovered quite well as regards ability but "how I feel" and how competent I am and for how long to recover to "normal" does vary - even with the same operation at 5-monthly intervals.

                    I recovered very well in all respects in my operation previous to last (5 months ago) and I asked my anaesthetist last week if he could get as good a post-op recovery too - and he duplicated the previous anaesthetic/s and I got all that I wanted in that regard - and I am very pleased with the outcome.

                    Here is a good run-down on POCD:

                    https://www.google.com.au/?gws_rd=ssl#q=pocd+%2B+age

                    It is essential that you/I be very honest with ourselves in this regard as if not taken seriously it can be "difficult" or potentially disastrous.

                    I try to realistically assess my level of competence on an on-going basis in terms of the level of risks needed and the degree of difficulty and level of safety of doing a task.

                    It is not difficult to do and becomes second nature after a while.

                      Hell, I am 82 and my cognitive ability is better than when I was 20--------
                      Except that I can't remember s%|t.

                        This is a clue that something you're sure of is probably wrong.

                          As we get older, things just seem to get harder. My neighbor just hit 71 and is finding it more difficult each year to manage the frustrations of using his computer. Just yesterday he downloaded his tax software for the 15th year in a row, and this time he could not overcome the security settings that kept the download from installing. Fortunately, I could bail him out.

                          I found this year that my beta blocker (prescribed 12 months ago) appeared to be causing cognitive problems. I went from winning 4/5 of the Words with Friends games to winning 1 in 5. I found myself forgetting what I was going to type in posts just like this. I found myself using inappropriate words... Soda when I meant milk. Cracker when I meant cookie, that kind of thing. When I stopped taking the Metoprolol those symptoms seemed to have diminished or disappeared.

                          I wonder how many symptoms of "old age" are actually the drugs that do so much to keep us alive.

                          At the end of the project, there is a profound difference between spare parts and extra parts.

                            Just an ounce of caution/prevention which beats the hell out of a pound or remedial treatment.
