The Four (4) Credibility Types – Web Examples (Item 2)

November 3, 2012 Leave a comment

Fogg (2003) has highlighted the four (4) types of credibility that separates some websites credibility from another. The types of credibility are; Presumed Credibility, Reputed Credibility, Surface Credibility and Earned Credibility. I’ll be showing four (4) example websites from the world-wide-web that describe each type of credibility.

Figure 1: Presumed Website Example (Source: WWF Global, 2012)

The following website example is that of a presumed credibility; ‘WWF Global’ is an organization which helps rescue animals, mainly pandas, from dangerous inhabitants and rescuing them from trafficking operations. They’re not only a globalized organization easily identified thanks to their efforts, but they’re constantly updating their website with information, have an extremely detailed FAQ and information link, and they’re primarily running through donations, which they show results due to the donations from the general public.

This website example is that of the reputed credibility type; this website is ‘The Escapist Magazine’ website, which discusses and reviews video-games across all platforms. Although the information may be opinionated, the reason this site has a high credibility is due to the website winning a ‘Webby’ award for the top video-game website. The website also has a strong fan base of people who share opinions, and the reviews of the games are extremely informative and the video-game research is correct; but when it comes down to the writer’s opinion on if he or she enjoys or likes the game is completely opinionated (which could lose credibility if people disagree with their opinion).

Figure 3: Surface Website Example. (Source: Bank West, 2012)

This website is a prime example of the surface credibility; The website is for ‘Bank West’, a highly professional bank located all around Western Australia. The reason why this website is an example of surface credibility is because it is presented professionally, and the site is easily an organization I recognize, especially through their advertisements on the television. All the informational pages within the website have citations and the website is easy to navigate through, with a simple tab on the right-side of the website to access online banking, and information about the bank is located on the left-side of the web-page.

Finally, we’re left with the final type of credibility, and that is earned credibility. The website example for earned credibility is ‘Google’. Google is a search-engine website, an extremely popular website, quiet possibly the most used website on the world-wide-web. The reason why this website is the perfect example for earned credibility is because it’s extremely easy to navigate the website, the links are quick and responsive when clicked, it gathers large amount of search results in a matter of seconds and the content that is processed is “fair and balanced”.

Performance Load Examples (Item 2)

November 2, 2012 Leave a comment

Here are some examples primarily discussed in the authors Lidwell, Holden & Butler’s (2003) article on Performance Load.

Figure 1: How Slot Machines Work (Source: How Stuff Works, 2012)

First (1st) example is the Slot machines. Slot machines back when they were new, the user had to pull a rather large lever placed on either side of the slot machine to make the slot machine spin. Now days, the slot machine can easily be spun by a press of the button. This is relevant towards performance load with the kinematic load aspect. Reason being, is that instead of increasing your kinematic load by using more effort in pulling a lever, you now can press a button, decreasing your kinematic load.

Second (2nd) example is the remote car keysCar keys are simple, you open the door by inserting the key into the car door lock and turning, thus opening the car door, same applies to turning on the engine. The introduction of the remote car keys has decreased performance load, specifically in kinematic load, by having a special set of buttons on the key that will unlock and lock the car doors while standing away at a distance. This helps when walking towards the car, pressing the button to unlock the doors, and simply opening the door and hopping into the vehicle, instead of increasing kinematic load and having to manually take your time opening the lock yourself.

Figure 2: Barcode (Source: Barcoding Inc., 2011)

Third (3rd) and final example of performance load is the bar code. Before bar codes were brought into existence, when purchasing a product, the cashier would have to type the products code into the computer themselves, increasing both the cognitive (remembering the digits) and kinematic (typing each digit into the computer). Now that the bar code has been introduced, the cognitive and kinematic loads have been significantly decreased, because now the cashier can simply swipe the product’s bar code across a scanner, scanning the digits into the computer themselves.
