Learning Portfolio 4 – Credibility

Learning Portfolio Item 1 (Critical Reading & Writing)

Question 1

Out of the millions of websites that are available on the internet it can sometimes be difficult to decipher which ones are trustworthy and credible. Trust is a large factory when determining what is credible. When it comes to credibility researchers have found that people evaluate trustworthiness and expertise and then combine them to develop an overall assessment of credibility (Fogg, 2003). When a website conveys both qualities,the user will find it credible. When a website lacks either trustworthiness or expertise, credibility will suffer. Because the internet is so easily accessible nearly anyone can create a website and because of this a website’s credibility can sometimes be difficult to determine.

After reading this it would be fair to say that the most credible sources would be those that are both trustworthy and have a high level of expertise.

To ascertain if a website is credible or not, further research must be conducted within that website. For example, research the credentials of the article to see if the article you are reading is credible or not. There are some websites out there that are created with the intent of committing fraudulent acts.

 

Question 2

Wikipedia is not a reliable because its information is not always guaranteed to be from a reliable source. Wikipedia is similar to an online encyclopaedia, it allows any user to edit or create an entry about any topic. Users that submit content or edit articles are not 100% guaranteed to be an accurate or credible source. There are some users that are known to vandalise the site and post biased opinions. Some users also post what they think is factual information, with the intent of contributing but sometimes they their information can be wrong.

A corporation could edit a profile to make themselves look better, therefore publishing a biased and possibly untrue article. Wikipedia can be a useful source to get small, basic information on a certain topic. Wikipedia can be used as a starting point, but it shouldn’t really be used as a credible source to gain important information from. And it’s because of all these reasons that it’s too unreliable trust with academic learning and referencing.

 

Question 3 

As it was shown in this week’s reading (Fogg, 2003), the internet has grown drastically between the years 1999 and 2002. As more people welcomed the internet into their lives more people started to use it for scams. With the ever expanding growth of the internet more and more users are becoming warier of the internet and the sites they visit and their credibility. It can be difficult to determine which sites are trustworthy in today’s technical society.

People should be wary of .org website because of:

  • People have become hesitant to use credit cards online as the internet has evolved there have been countless scams that have made people feel unsafe declaring their credit card information.
  • Users now feel more secure when sites have visual proof of being a physical reliable company. In today’s day and age as more and more companies are based online people are sceptical as to if they are legitimate or not.

 

 

Activity

Reputed Credibility

Westac Online Banking

The Westpac Online Banking website has reputed credibility because it is one of Australia first banks as well as having good reputation nationwide.  It deals with online banking and transfers, because it is dealing with such sensitive content you need a website to be secured. Normally if there is a little padlock in the URL bar it is a trustworthy site and it’s safe to enter your personal information.

 

Presumed Credibility

tafe

 

Central Tafe website has presumed credibility because of the .edu address. Websites of education institutes are presumed credible by users because they appear to be trustworthy and are needed to be trustworthy also.

 

Earned Credibility

hoyts

Hoyts website has earned credibility because it looks enticing and it’s professionally designed.  It is a trusted cinema in Australia and has earned its reputation. The site is relatively easy to navigate and it is updated daily. The content is unbiased and provides information on screening times.

 

Surface Credibility

Ninemsn

Ninemsn has surface credibility it appears like a trustworthy news site. It always has current affairs news, but it doesn’t always go in depth on the important stories. But it also focusses heavily on celebrity gossip and reality TV stars and television.

Learning Portfolio 3 – Performance Load

Question 1

Performance load is the degree of mental and physical activity required for completing a task. If you have a high performance load, performance time and errors are bound to increase and the likelihood of successfully completing the task decreases. If your performance load is low your performance time and errors diminish, and the chance of successfully accomplishing your goal increases.

There are two types of performance loads: Cognitive and Kinematic.

Cognitive load, as the name suggests is the amount of brain power, perception, memory and problem solving required for solving a problem or completing a task.“Cognitive load theory is a comprehensive and proven instructional theory that illustrates ways to reduce unproductive forms of cognitive load and at the same time maximize productive sources of cognitive load that lead to efficient learning environments.” (Clark, R., Nguyen, F., & Sweller, J., 2011).

Kinematic load is the amount of physical activity that is required to complete a task. Lidwell, Holden, & Butler use the telegram as an example and explained it as “The number of taps to communicate a message was the kinematic load for that task” (Lidwell, Holden, & Butler, 2010). The kinematic load can be minimised by eliminating steps that are not essential to complete a task.

When I was learning how to write HTML and CSS we were not allowed to use Dreamweaver we had to use Notepad, so we had to remember all the different commands and tags needed to create a working HTML page. That was the cognitive load for that task trying to remember what came next and if I had used the right sequence and trying to figure out where you made a mistake if the code doesn’t work. The use of Dreamweaver cut down my work load and cognitive load significantly with short cuts and code hints.

Question 2

Chunking is a technique that can be used to make remembering relatively lengthy strings of information a little bit easier. It is particularly useful when we only need to remember something for a short period of time. Chunking involves taking long strings of information and grouping (chunking) them into smaller more manageable bits of information.

“The reason the brain needs assistance is because of the working memory, which is where we manipulate information, holds a limited amount of information at one time” (Malamed, 2009).

Chunking when in relation to design should be applied to information users will need to recall and or commit to memory. Chunking can help users hold onto the information they need when confronted by other competing stimuli.

Chunking can help to improve cognitive load in design and visual communications as users will not have to analyse or remember a number of different pieces of information. They will instead be directed to one “chunk” of material which gives them adequate information.

Here is a good example of chunking in visual design from the Nike website.

Chunking works on the premise that the average human’s working memory can be quite easily overloaded by excessive detail. The ultimate way to avoid this dilemma of being overwhelmed by indigestible information is to arrange it in small, meaningful units that can be strung together to appear much less daunting.

 

Question 3

Psychology is an important part of visual design. People often have psychological reactions upon seeing certain designs. As we saw in learning portfolio 1, aesthetics play a major role in population’s response to a design. Aesthetics can either produce positive or negative emotional responses to specific designs.

Designers often use Gestalt Theories (developed by German psychologists in the 1920s, Gestalt theories explain how people tend to organise visual elements into groups, and how the whole is often greater than its parts (Taylor 2013)).Used Gestalt principles in a logo can make it more interesting, more visually engaging and therefore it makes the message more memorable.

And of course colour symbolism plays a huge role in visual design. Different colours are said to evoke different emotions, and in turn that plays a major role in psychology of design. You wouldn’t want to do the branding and logos for a depression website in black and dark colours because that’s not the first thing someone wants to see when seeking help.
