Perceptual and Cognitive Processes

Our brains automatically interpret sensory information even before we become consciously aware of it.

Our minds are adept at processing visual cues, frequently relying on past encounters to fill in gaps and instinctively form conclusions in line with our anticipations.

The mind actively constructs and supplements visual information, rather than merely recording it.

Susan Weinschenk emphasizes that our visual perception does not simply replicate our surrounding environment. Our brains constantly fill in gaps and create mental shortcuts based on our past experiences when processing visual data. She uses optical illusions like the Kanizsa triangle and rectangle, where we perceive complete shapes that are actually just implied by strategically placed lines and circles. Our brain tends to complete gaps with anticipated data, as it constantly looks for recognizable patterns. Our brains construct our visual experiences in such a way that our perceptions do not always correspond with the actual situation.

Weinschenk posits that the active construction has particularly significant consequences in the realm of design. You can leverage this tendency by strategically using shapes and colors to guide viewers' interpretations. She illustrates the way in which color enhances a particular message despite both elements being equally prominent. Designers need to be aware that their decisions can shape the perceptions of their audience, taking into account the prior knowledge and anticipations of that audience. Simply sharing information is insufficient; understanding how people will process and understand that information is crucial, taking into account their cognitive biases and mental shortcuts.

Context

• This refers to the amount of mental effort being used in the working memory. When visual information is complex or incomplete, the brain uses shortcuts to reduce cognitive load, which can lead to constructed perceptions.
• These are systematic patterns of deviation from norm or rationality in judgment. In visual perception, biases can lead us to see what we expect to see, rather than what is actually present.
• The perception of these illusions can be influenced by the surrounding context, which can alter how the brain interprets the visual cues.
• The brain's tendency to complete gaps allows it to focus attention on more critical tasks by quickly resolving less important visual information.
• This is the tendency to perceive objects as unchanging despite changes in sensory input, such as lighting or angle. It shows how the brain maintains a stable perception in a dynamic environment.
• Visual design can evoke emotions, influencing how information is received and remembered. Designers can use this to create more engaging and memorable experiences.
• Consistent use of specific shapes and colors helps reinforce brand identity, making a brand more recognizable and memorable to consumers.
• High contrast between text and background colors can enhance readability and comprehension, making the message clearer and more impactful.
• The study of signs and symbols and their use or interpretation can help designers understand how visual elements communicate meaning beyond their literal appearance.
• Providing users with feedback on their actions helps them understand the consequences and learn how to interact with a system more effectively.
• Designers can use knowledge of cognitive biases to influence decision-making. For example, the scarcity effect, where people perceive scarce items as more valuable, can be used in marketing to encourage purchases.

Our mind rapidly processes sensory data, using past experiences to predict what may happen next.

Our brains are constantly bombarded with an immense variety of sensory data every second. Weinschenk suggests that our mental processes are adept at quickly evaluating the sensory input and interactions we face, despite being bombarded with a vast array of information. Our environment triggers immediate responses rooted in our history and pre-existing notions, thus bypassing the need for deep conscious deliberation.

Designers need to understand that their perception of clarity and obviousness might not be shared by the user. Weinschenk underscores that when individuals engage with digital platforms, they do so with a unique blend of previous experiences and expectations. To create designs that resonate, thorough research is crucial to understand the mental models established by your target audience. Neglecting this aspect can lead to confusion and annoyance, ultimately causing users to give up on the products. She delves into examples like door handles that suggest pulling when they actually need to be pushed, or website navigation options that are confusing. When the designer's vision does not align with the user's expectations, it frequently results in a less than satisfactory exchange.

Practical Tips

• Experiment with disrupting your routine to challenge your brain's predictions. Take a different route to work, try new foods, or listen to a genre of music you usually avoid. Pay attention to how these changes affect your anticipation of events and your reactions. This can help you understand the flexibility of your predictive processes and how they adapt to new information.
• Develop a habit of 'speed journaling' to capture your immediate thoughts and reactions to daily events. Set aside a few minutes each day to write down your thoughts about recent interactions or experiences as quickly as possible. This practice can help you become more aware of your instinctual responses and improve your ability to process and articulate your thoughts swiftly.
• Create a personal reaction journal to track how different environments influence your immediate responses. Carry a small notebook with you or use a digital app to jot down your reactions when you enter new or...

100 Things Every Designer Needs to Know About People Summary Exploring the factors that propel motivation and inform decision-making.

Our choices are often shaped by factors that operate beyond our conscious awareness.

This section challenges the notion of rational decision-making, highlighting the powerful role of unconscious factors in shaping our choices.

Decisions are often reached through subconscious processes influenced by societal expectations, emotional states, and established behaviors.

Weinschenk posits that, against common assumptions, the majority of decisions stem from processes other than conscious logical reasoning. Our actions are significantly influenced by subconscious mechanisms, such as our emotions, established routines, societal norms, and the inclination to steer clear of mental discomfort when holding conflicting beliefs. Our cognitive processes initiate responses to potential threats during the decision-making stage, even before we are consciously aware of such dangers, as she references in her work.

For designers, this means understanding your target audience's unconscious motivations and triggers. Weinschenk emphasizes the potential for inaccuracy when depending on users' own accounts of how they make decisions. Designers ought to delve into various methods to gain a...

Interpersonal connections and forming bonds

This part explores how our inherent need to interact socially influences our behavior and extends to the way we interact with technological systems.

Individuals can sustain only a finite number of close relationships.

The publication authored by Susan Weinschenk explores a concept derived from anthropological studies on the social interactions of primates, referred to as Dunbar's number. Dunbar suggests that there is a limit to the stable social relationships a person can sustain, which is generally about 150. In these connections, we acknowledge the distinctiveness of each individual while also appreciating their collective interdependence within the group.

Designers must determine whether social elements in digital products aim to foster deep engagement within a close-knit circle or whether they seek to appeal to wider circles with interactions that are more superficial. In closely connected groups, Weinschenk advises that designers should encourage interpersonal communication, customize interactions for each person, and highlight the distinct connections between community participants. Communities characterized by less...
