61 Dot-Estimation Task This study concerns determination of your group classification based on a particular type of cognitive style that relates to how visual imagery is processed. According to Hoffman and Routledge (2004), people can be reliably divided into two cognitive categories: dot-overestimators and dot-under-estimators. Following a series of studies, Hoffman and Routledge (2004) concluded that these two groups are distinguished by several differences. For example, variation between the groups on the dimensions of analytical problem solving ability, degree of cognitive bias, literacy, mathematical ability, and social competence, have all been identified. In this study you will complete a dot-estimation task, which we will use to determine your group classification. You will be shown a series of pictures of dots and be asked to estimate the approximate number of dots in each one. Please provide your initial, immediate guess which will be used to determine your classification: dot-under-estimator and dot-over-estimator. Such groups differ in cognitive style, and we are interested in the effects of this form of classification for new psychological characteristics. Specifically, we are interested in your perceptions of others in terms of similarity and differences. Please begin the Dot Estimation Task.

62

63 You will be presented with a series of pictures containing dots. Your task is to estimate the number of dots in the picture. We want you to give your best, instinctual guess. There will be ten pictures presented and each picture will be shown for ½ second. First, on the next page is a practice task to get you used to the format. Please make a quick estimation of the number of dots in the picture. You will only see the dot image for 1/2 second. How many dots would you estimate were in this picture?

64

65 Ok, that was the practice, now you will complete a series of actual dot estimation tasks. Remember, you will only see each image for half a second. How many dots would you estimate were in this picture?

76 Your responses indicate that you are part of the dot-under-estimator group. The test you just took examines individuals differences in cognitive style. Please correctly identify your group from the list below. o o o o ball-under-estimator dot-over-estimator ball-over-estimator dot-under-estimator

77 In-Group Crowding Manipulation In this next part of the study, we are interested in your perceptions of other people in terms of similarity and differences. Below you will find a picture of a group of people. This is a picture of dot under-estimators (i.e., the same group as you) taken when Drs. Hoffman and Routledge, the inventors of the two different cognitive styles, invited dot-under-estimators to their annual convention. Please describe three ways in which you think you might be similar to the dot-under-estimators in the picture.

78 Now, please carefully look again at the picture of your group above and then imagine that you are present in the scene. Visualize the scenario in as much detail as possible.

101 Prevention Condition This part of the study evaluates health care messages. The message to below was developed by the association of dental hygiene to educate college students. Please read the following carefully and provide your honest opinions on the next page. IMPORTANT: NOTE THAT ONCE YOU PROCEED TO THE QUESTIONS PAGE, YOU WILL NOT BE ABLE TO RETURN TO THE ARTICLE. How You Can Prevent Gingivitis Gingivitis is a serious and very common dental condition, but it is 100 per cent preventable and easily treated if you have it diagnosed early. So if you begin to notice the signs of gingivitis, then you need to pay a visit to you dentist for a recommended treatment plan. The condition is caused by an overgrowth of bacteria inside the mouth that converts into plaque and leads to bad breath, bleeding gums and often sore or swollen gums. If you leave the condition for too long, it can cause more serious conditions such as tooth loss, periodontal disease and even heart disease. You can easily prevent the condition from occurring by combining good home dental practices with regular dentist visits. By brushing, flossing and rinsing twice a day at home using the correct technique and then having a professional clean twice a year at your dentist, the instance of gingivitis is drastically reduced.

102 Before you brush, you should floss your teeth and get all the bacteria and food particles that get trapped between the teeth out. Brushing with then help to get rid of the bacteria on the tooth surface and get rid of plaque. Using a natural toothpaste that is based on mint oil is the best choice as it is both effective and gentle on your body. Mint oil is a naturally powerful antibacterial agent and also has anti-fungal properties. In contrast commercial toothpastes contain detergents, which can act as allergens for many people. Mouthwash is another essential part of a good dental routine. It is able to kill bacteria left over in the mouth, particularly the bacteria that gets stuck around the gum line. Additionally, scraping your tongue can also get rid of a lot of bacteria that can lead to gingivitis. You can buy tongue scrapers, or alternatively, use your regular tooth brush. Protecting your dental health from the onslaught of gingivitis is relatively easy, but the key is consistency. You have to ensure that you are brushing, flossing and rinsing twice a day to prevent the build up of harmful bacteria in the mouth. When you visit your dentist you should discuss how you can best prevent gingivitis and other dental conditions and ask them to show you how to most effectively brush your teeth as many people do not use the right technique.

103 Promotion Condition This part of the study evaluates health care messages. The message to below was developed by the association of dental hygiene to educate college students. Please read the following carefully and provide your honest opinions on the next page. IMPORTANT: NOTE THAT ONCE YOU PROCEED TO THE QUESTIONS PAGE, YOU WILL NOT BE ABLE TO RETURN TO THE ARTICLE. How You Can Get Brighter Smiles Everyone loves a bright white smile. Fortunately there are a variety of procedures and products available today that can improve the look of yours. When exploring these options it's wise to know the difference between "teeth whitening" and "teeth bleaching" and familiarize yourself with cosmetic dentistry and its terminology. With so many companies offering their magical teeth whitening treatments, it's easy to feel overwhelmed. To counteract the influx of these potentially bogus programs, several websites have recently popped up with accurate and easy to digest information regarding your teeth. Whitening one's teeth is the process of restoring teeth to their natural color. This is done by removing the build-up and dirt collected on the tooth's surface. You can achieve these results with toothpastes that boast a whitening agent. Having your teeth cleaned regularly is an excellent way to keep your teeth free of debris.

104 Bleaching one's teeth actually whitens teeth beyond their natural state to produce its desired result. The use of a bleach-containing agent will draw out the stain and color leaving them clean and whiter than before. There are two types of bleach used in this process. Hydrogen peroxide is used by your dentist in a controlled environment and contains a high level of peroxide. Takehome kits use carbamide peroxide which has a lower percentage of peroxide and is therefore safer to use on your own. Over-The-Counter teeth bleaching products can be purchased at your local drugstore for the most affordable prices. A good choice would be one that uses a tray (as a dentist would) that covers the teeth and holds the peroxide-based gel in place over your teeth. Other options include strips and "paintable" teeth whitening gel. Many toothpaste brands incorporate peroxide as a way to bleach teeth while brushing. Professional take-home teeth bleaching kits are slightly more expensive but are dentist-approved and therefore more reliable. They utilize the tray process and are custom fitted for your teeth. This makes them more effective than over-the-counter brands. Custom molded trays may take several weeks to receive so plan accordingly. The long and the short of it is that teeth whitening works. Virtually everyone who opts for this cosmetic treatment will see moderate to substantial improvement in the brightness and whiteness of their smile. However, teeth whitening is not a permanent solution and requires maintenance or "touch-ups" for a prolonged effect.
