A Hypnotic Suggestion Can Generate True And Automatic Hallucinations -
The nature of hypnotically suggested changes in perception has been one of the main topics of controversy during the history of hypnosis. The major current theories of hypnosis hold that we always actively use our own imagination to bring about the effects of a suggestion. For example the occurrence of visual hallucinations always requires active use of goal directed imagery and can be experienced both with and without hypnosis. The study published in PLoS ONE was done with two very highly hypnotizable participants who can be hypnotized and dehypnotized by just using a one-word cue. The researchers measured brains oscillatory activity from the EEG in response to briefly displayed series of red or blue shapes (squares, triangles or circles). The participants were hypnotized and given a suggestion that certain shapes always have a certain color (e.g. all squares are always red). Participant TS-H reported constantly experiencing a change in color immediately when a suggested shape appeared on the screen (e.g. seeing a red square when the real color was blue).
The researchers found that this experience was accompanied with enhanced high-frequency brain activity already 1/10 second after the stimulus appeared and it was only seen in response to the shapes mentioned in the suggestion. The second participant did not experience the color change or the enhanced activity. This enhanced oscillatory brain activity is proposed to reflect automatic comparison of input to memory representations. In this case the hypnotic suggestion "all squares are red" led to a memory trace that was automatically activated when a square was presented. Furthermore, for the participant TS-H the effect was strong enough to override the real color of the square. The matching must have occurred preconsciously because of the early timing of the effect and the immediacy of the color change. Also, both participants reported having performed under posthypnotic amnesia without conscious memory of the suggestions. In the article published in International Journal of Clinical and Experimental Hypnosis TS-H was tested in a similar type of setting, however, only behavioral data, including accuracy and response times in color recognition, were collected. These results further support that a hypnotic suggestion affects her color perception of targeted objects before she becomes conscious of them. Furthermore, TS-H was not capable of changing her experience of visually presented stable images without the use of hypnotic suggestions i.e. by using mere mental imagery. Importantly, both of these experiments were done by using a posthypnotic suggestion. The effect was suggested during hypnosis but the experience was suggested to occur after hypnosis. Thus all the experiments were carried out while participants were in their normal state of consciousness. This result indicates that all hypnotic responding can no longer be regarded merely as goal directed mental imagery. It shows that in hypnosis it is possible to create a memory trace that influences early and preconscious stages of visual processing already about 1/10 second after the appearance of a visual target. This result has important implications in psychology and cognitive neuroscience especially when studying visual perception, memory and consciousness.
It鈥檚 hard to tell from the video as the driver doesn鈥檛 really accelerate, but some pops and crackles on the overrun suggest it could be a turbo. There is also a faint bass, deep undertone which to us suggests it is likely to be turbocharged. Regardless, it will come in as the most powerful road-going Boxster ever created. Coinciding with the potent engine, the rest of the running gear is likely to be beefed up. We鈥檙e talking about bigger brakes, stiffer suspension, extra chassis bracing, and a neat aero kit to help with downforce and to reduce lift at high speed. Of course, the Spyder will also feature a soft-top roof in traditional Spyder format. This prototype shows the rag-top removed, leaving a chunky engine cover with twin buttresses drawing downward. All of this is set to help reduce overall weight. Given the fact this prototype is hardly camouflaged at all, Porsche will probably unveil the 718 Boxster Spyder some time later this year, with sales expected to start soon after. It鈥檚 likely to be a special edition model built in limited numbers only.
I may have trouble with one horse power (horseback riding), but give me 355 horses and I am on my way. I had the luxury experience to drive a new 2006 Porsche 911 Carrera S while in Switzerland, which was made available from the hotel Palace Luzern. The Palace Luzern, in conjunction with Porsche, makes available, for the price of the gas, a Porsche for guests staying at the hotel to drive. You only need to provide your signature, acknowledging the insurance responsibility, and you are presented the keys and a map for your drive around the breathtaking area surrounding Lucerne, Switzerland. As any good race car driver or actually any driver would do, I had to check out all the features available to me for my drive. So, what did I have to work with? A 6 speed manual transmission, a 6 cylinder 355 hp engine at 6,500 rpm with 295 lb-ft torque at a compression ration of 11.8-1; translated, I was not going to be riding behind any cars during my drive.
To balance out the ride there is a 4-piston aluminum monobloc fixed calipers, vacuum servo, ventilated, and drilled, ABS braking system, as though I was going to need this feature, but it was nice to know that it was there. The weather was favorably warm for a late October journey through Switzerland, so of course we had the sunroof open and we enjoyed the beautiful sunshine. Lucerne is located in such a beautiful location with the mountains and the lakes surrounding it, although having traveled a bit of Switzerland I guess that this statement would fit most of Switzerland. It was a bit hard taking in the scenery when most of the surroundings are a blur, but we did slow down as we passed through the many charming towns. Short shifting and powering through turns, downshifting for speed so we could watch the cars in our rearview mirror; I believe that Debra had wished we had a 3 point harness for a seatbelt. We cruised a few hours north of Lucerne before doubling back to meet with a friend in the town of Willisau where we went on a tour of the Diwisa Distillery where they make Xellent Swiss Vodka. I, being of sound mind, body, and remembering the insurance note I signed regarding the Porsche, did not partake in any of the samples. We enjoyed the educational and informative tour of the Diwisa Distillery, but alas it was time to fire-up the engine and cruise back to Lucerne, though we did take a few turns to extend our seat time. Recalling my physics classes, "two objects cannot occupy the same space at the same time," translated, that is what the accelerator pedal was for; I used this feature to its proper functionality. The navigation system worked to perfection as it told me in a calm and engaging voice 'where to go,' and I enjoyed it. Debra noted how smooth the ride was regardless of the speed, so our experiment was a success.
