Analysis of Website Applications Based on Selected Principles
1. Choose 10 principles from the list below.
2. Choose 1-3 websites that were not used before by anyone and were not used in class to analyze based on your chosen 10 principles.
3. Describe an appropriate application of 5 of your principles and an inappropriate application of the other 5 according to the template: include an explanation of the theory relevant to each principle and demonstrate either a positive or a negative application of the principle. Please use the template in the attached link for each principle. Write a paragraph explaining the theory taught in class, add a screenshot of the principle's application, and explain how it was applied in the website/app. For principles that were not applied well, add an explanation describing what should be changed.

Principle 1: Color - Basic Color Perception Using 3 Different Cone Types
Theory Explanation:
The principle of basic color perception is rooted in the human eye's three types of cone cells, which are sensitive to different wavelengths of light (red, green, and blue). The combination of these cones allows us to perceive a wide spectrum of colors.
Positive Application:
Website: Coolors.co
Screenshot: Coolors.co Color Scheme (insert a real screenshot of the website)
Application Explanation:
Coolors.co utilizes a color palette based on the principles of basic color perception by allowing users to generate and explore various color combinations. The interface effectively showcases the RGB spectrum, enabling designers to create visually appealing palettes that appeal to the three types of cones in human vision. The use of distinct colors enhances user engagement and facilitates creativity.
Principle 2: Color - Maximum Contrast - Using 3 Pairs of Maximum Contrast
Theory Explanation:
Maximum contrast refers to the use of colors that are far apart on the color wheel, enhancing visibility and clarity. This principle is essential for readability and user accessibility.
Positive Application:
Website: Khan Academy
Screenshot: Khan Academy Contrast (insert a real screenshot of the website)
Application Explanation:
Khan Academy employs maximum contrast effectively in its educational materials. The website uses dark text on a light background, ensuring high readability and accessibility for users of all ages. This design choice helps students focus on learning without straining their eyes, demonstrating an appropriate application of maximum contrast principles.
Principle 3: Loss Aversion - Framing
Theory Explanation:
Loss aversion suggests that individuals prefer to avoid losses rather than acquiring equivalent gains. The way information is framed can significantly influence decision-making.
Positive Application:
Website: Headspace.com
Screenshot: Headspace Framing (insert a real screenshot of the website)
Application Explanation:
Headspace frames its meditation sessions as a way to "gain" peace of mind rather than simply "losing" stress. By highlighting the positive outcomes of using their app, they effectively leverage loss aversion to encourage users to engage in mindfulness practices regularly.
Principle 4: Working Memory - Capacity-Processing Tradeoff
Theory Explanation:
The capacity-processing tradeoff refers to the limitations of working memory, where increasing cognitive load can hinder processing ability. This principle suggests that simplifying information can enhance understanding.
Inappropriate Application:
Website: Headspace.com
Screenshot: Headspace Complexity (insert a real screenshot of the website)
Application Explanation:
While Headspace provides valuable content, certain sections overwhelm users with too much information at once, such as lengthy descriptions of meditation techniques and benefits. This complexity can exceed working memory capacity, making it difficult for users to retain and process essential information effectively. To improve this aspect, Headspace could simplify content by breaking it down into shorter, more digestible segments.
Principle 5: Trust
Theory Explanation:
Trust in digital contexts refers to the user's confidence in a platform's reliability, security, and intention. Building trust is crucial for user engagement and retention.
Inappropriate Application:
Website: Coolors.co
Screenshot: Coolors.co Trust Issues (insert a real screenshot of the website)
Application Explanation:
While Coolors.co is a useful tool for designers, it lacks robust privacy policies or clear information about how user data is handled. This absence may lead to trust issues among users who are concerned about data security. To build greater trust, Coolors.co should provide transparent data protection policies and reassure users about their privacy rights.
Conclusion
Analyzing the applications of selected principles across different websites reveals both effective and ineffective implementations of psychological theories in design and usability. Websites like Khan Academy and Headspace demonstrate positive applications that enhance user experience through principles like color perception and loss aversion framing. Conversely, areas such as working memory management and trust require improvements in platforms like Headspace and Coolors.co. By understanding and applying these principles thoughtfully, developers can create more engaging and user-friendly digital experiences.
