In the previous article, I introduced the main concepts and methods of cognitive psychology, and how it relates to the brain and the SoC. I also explained what a smartphone SoC is, and what are its main components and functions. I also stated the main purpose and objectives of this series, and provided an overview of the topics that I will cover in the next articles.

In this article, I will explore how the brain and the SoC receive and filter information from the external world, and how they select and focus on the relevant stimuli. I will compare and contrast the sensory systems of the brain and the input devices of the SoC, and how they encode and transmit information. I will also discuss the factors that affect perception and attention, such as expectations, context, motivation, and interference.

What is Perception and Attention and Why are They Important?

Perception and attention are two fundamental cognitive processes that enable us to interact with the environment and make sense of the world. Perception is the process of acquiring, interpreting, and organizing sensory information from the environment. Attention is the process of selecting, directing, and maintaining focus on the relevant sensory information.

Perception and attention are important for several reasons. First, they allow us to perceive and recognize objects, events, and patterns in the environment, and to form mental representations of them. Second, they enable us to filter out irrelevant and distracting information, and to allocate our limited cognitive resources to the most important information. Third, they influence our memory, learning, thinking, and problem-solving, as they determine what information we encode, store, retrieve, and use.

Perception and attention are also influenced by several factors, such as our expectations, context, motivation, and interference. These factors can affect how we perceive and attend to the sensory information, and how we interpret and respond to it. For example, our expectations can shape our perception and attention, as we tend to perceive and attend to what we expect to see or hear. Our context can also affect our perception and attention, as we tend to perceive and attend to what is relevant and meaningful to our current situation and goals. Our motivation can also influence our perception and attention, as we tend to perceive and attend to what is rewarding and satisfying to our needs and desires. Our interference can also impact our perception and attention, as we tend to perceive and attend to what is novel and surprising, or what is threatening and alarming.

How Do the Brain and the SoC Process Information from the Environment?

The brain and the SoC are both systems that process information from the environment, but they do so in different ways. The brain and the SoC have different sensory systems and input devices, and they use different methods and mechanisms to encode and transmit information.

The Sensory Systems of the Brain and the Input Devices of the SoC

The brain has five main sensory systems that receive information from the environment: vision, hearing, touch, smell, and taste. Each sensory system has specialized receptors that detect and convert physical stimuli, such as light, sound, pressure, chemicals, and temperature, into neural signals. These neural signals are then sent to the brain through the sensory nerves, where they are processed and interpreted by different regions of the brain.

The SoC has various input devices that receive information from the environment, such as camera, microphone, touchscreen, accelerometer, gyroscope, GPS, and Wi-Fi. Each input device has specialized sensors that detect and convert physical stimuli, such as light, sound, electric current, motion, location, and wireless signals, into digital signals. These digital signals are then sent to the SoC through the input interface, where they are processed and interpreted by different components of the SoC.

The Encoding and Transmission of Information by the Brain and the SoC

The brain and the SoC use different methods and mechanisms to encode and transmit information. The brain uses analog and parallel methods and mechanisms, while the SoC uses digital and serial methods and mechanisms.

The brain encodes information in analog form, which means that the information is represented by continuous and variable neural signals that vary in intensity and frequency. The brain also transmits information in parallel, which means that the information is sent simultaneously through multiple pathways and channels that have different functions and destinations.

The SoC encodes information in digital form, which means that the information is represented by discrete and fixed binary signals that have only two values: 0 or 1. The SoC also transmits information in serial, which means that the information is sent sequentially through a single pathway and channel that has a common function and destination.

How Do the Brain and the SoC Compare and Contrast in Terms of Perception and Attention?

The brain and the SoC have some similarities and some differences in terms of perception and attention. Here are some of the main points of comparison and contrast:

  • The brain and the SoC both have multiple sensory systems and input devices that receive information from the environment, but they differ in the types and number of stimuli that they can detect and process. The brain can detect and process more types and more complex stimuli than the SoC, such as emotions, meanings, and abstract concepts. The SoC can detect and process more precise and more consistent stimuli than the brain, such as numbers, codes, and algorithms.
  • The brain and the SoC both encode and transmit information in different forms and methods, but they differ in the speed and accuracy of their processing. The brain can process information faster and more flexibly than the SoC, as it can use parallel and analog methods and mechanisms that allow for more simultaneous and variable processing. The SoC can process information more accurately and more reliably than the brain, as it can use serial and digital methods and mechanisms that allow for more sequential and fixed processing.
  • The brain and the SoC both use perception and attention to filter and select the relevant information from the environment, but they differ in the factors and strategies that affect their perception and attention. The brain is more influenced by top-down factors, such as expectations, context, and motivation, that shape its perception and attention based on its prior knowledge, goals, and needs. The SoC is more influenced by bottom-up factors, such as interference, novelty, and salience, that shape its perception and attention based on the properties and features of the stimuli. The brain also uses more strategies to enhance its perception and attention, such as attentional control, selective attention, divided attention, and sustained attention. The SoC uses fewer strategies to enhance its perception and attention, such as attentional allocation, focused attention, and switching attention.
