The Uncanny Valley

At first glance, the character above appears almost human—but something about her smile, her eyes, or her facial expression is odd. That unease isn’t just your imagination; it is the Uncanny Valley at work. This photo is from The Polar Express, a film often notorious for its hyper-realistic animation that lands uncomfortably between cartoon and human. Hopefully, you felt something was off—that’s the psychological effect at work. Holly, also called “Hero Girl,” is a lot more realistic than, say, a cartoon Superman. And yet, despite more realistic, she triggers more discomfort because she is almost—but not quite—human.

The Uncanny Valley was originally developed in 1970 by Japanese robotics engineer Masahiro Mori. At face value, this phenomenon might just seem like an instinct you have and nothing more, but there is a whole lot more. 

The process of analyzing human faces and emotions is complex, involving a network of brain regions like the fusiform face area (FFA) and amygdala, working together to interpret facial expressions and extract meaning for social interaction. The specific patterns of facial muscle activity that create emotional expressions have been shaped over millions of years. Three main ideas attempt to explain the origin of this effect.

The Uncanny Valley is not just a feeling you get in your gut when you look at something off—it’s the product of deeply-rooted psychological and evolutionary mechanisms

The evolutionary theory suggests that there was a point in history where evolution required slight deviations from human-like features to trigger discomfort; examples of this could be people who could be potentially dangerous or diseased individuals. 

Another idea is cognitive dissonance, defined as the mental discomfort felt when people hold attitudes or beliefs that conflict with their behaviors. In this case, when something looks human, people then subconsciously hold expectations of human-like behavior—when this expectation is not met, though, people may feel cognitive dissonance, consequently leading to a feeling of uneasiness. 

Finally, impaired empathy is the inability to understand or share the feelings of other people. Small cues such as facial expressions and body language are extremely important to human interaction and socialization. Similar to dissonance, when these boxes are left unchecked, it creates complications in our ability to truly connect—impaired empathy—adding to the sense of eeriness. 

The Uncanny Valley is not just a feeling you get in your gut when you look at something off—it’s the product of deeply-rooted psychological and evolutionary mechanisms. Our brains have spent millions of years being able to recognise human faces and to ring an internal alarm when something looks human but doesn’t feel quite right. From unnatural movements to abnormal reactions, these things disrupt our set of expectations, triggering discomfort. 

As AI and hyper-realistic technology become a growing part of our daily lives, we can see why this valley matters. With growing exposure to these almost human-like entities, it can blur the line between human and machine. The more we interact with “almost-humans,” the more the line between real and artificial grows thinner, challenging our very sense of what it means to connect.

Discipline Dilemma: Understanding Corporal Punishment

Parents have a duty to discipline their children. When children do something wrong, their parents should discipline them to teach a lesson. 

One of the most common manifestations of discipline is physical punishment, otherwise known as corporal punishment. Corporal punishment can refer to a variety of actions, from slapping, spanking, and even prolonged periods in a fixed position. However, this form of punishment has raised questions regarding effectiveness and ethics. How effective is corporal punishment? What are its effects? Is it morally just to administer such punishment on a child? 

In schools across the United States, corporal punishment is still considered a valid form of punishment in 19 states. Corporal punishment is more prevalent in states in the South, such as Alabama, Arkansas, and Mississippi (National Institute of Health). In a second study published by the National Institute of Health, researchers surveyed a group of parents bringing in their children to a clinic, asking about their position on corporal punishment. Based on this survey, 51% of these parents showed support for forms of corporal punishment, 37% disagreed, and the rest took no clear position. Dovetailing this finding, Columbia University’s Demographic and Health Surveys show that in 2015, nearly 40% of children under the age of five were exposed to some form of physical punishment in their lives. Surveys from the United Nations International Children's Emergency Fund (UNICEF) show that hundreds of millions of 2-to-4 year olds still experience corporal punishment globally. Corporal punishment remains a common choice for parents as a form of discipline in homes, with almost one third of U.S parents reporting spanking their children weekly. 

Clearly, corporal punishment is common—but is it also effective? Psychologist Elizabeth Thompson Gershoff of the National Center for Children in Poverty at Columbia University conducted a meta-analysis in which over the course of 62 years, she attempted to unveil the consequences of corporal punishment. In her study, Gershoff discovered that for most cases, corporal punishment was linked to continuous negative behavior in kids and did not seem to have an overwhelmingly positive result. However, it was also highlighted in her study that there did seem to be an immediate, temporary obedience from the children after they received the punishment, though this did not last. Gershoff finds that the severity and how often a child is punished plays a significant factor in determining its outcome, where the more often and harder the punishment, the more likely an aggressive behavior begins to show. This underscores how subjective corporal punishment can be, with many different variables being at play to determine the outcome of punishment inflicted on children. Ultimately, however, Gershoff’s studies have found that there is a correlation between corporal punishment and negative behaviors among children and advises parents to avoid administering such discipline.

Children need to understand boundaries and I think that children need to understand that there should be punishments… in direct proportion to the improper behavior that they might demonstrate.

Conversely, many parents still argue that corporal punishment is necessary and an effective way to discipline children. For instance, an article published by Britannica argued that corporal punishment is a valid form of punishment when used in moderation. The article explained how more moderate punishments, such as a time-out, would not be effective on more severe behavior. A sharper form of punishment, such as corporal punishment, would overall yield better results in teaching children a lesson when considering certain forms of behavior. Moreover, the same article argued that the physical consequence better establishes boundaries and forces children to continue to behave in the future. President and Dean of the Charles H. Mason Theological Seminary Harold Bennet mentions that “children need to understand boundaries and I think that children need to understand that there should be punishments… in direct proportion to the improper behavior that they might demonstrate.” Overall, the debate surrounding corporal punishment has still remained complex and polarizing. It is crucial for parents, educators, and policymakers to weigh both sides of the debate and strive to create an environment for children to learn, grow, and develop. 

Cognitive Processes

You wake up in the morning and start to get ready, going through your daily morning. Brushing your teeth, taking a shower, eating breakfast, getting dressed. You then get ready to leave the house, putting shoes on and deciding on how to make your commute. All of these rudimentary actions involve critical cognitive skills. From deciding on what to eat and what to wear, to remembering what commute is the fastest, to simple things such as knowing to brush your teeth involve cognitive skills. Such skills such as thinking, judging, and remembering play a major role in human life. Cognitive processes, also known as cognitive functions or skills, are the psychological functions the brain performs in order to take in and process information received. Information is received through the five basic senses.  This information is then analyzed, stored, and then used in making relevant decisions in everyday life.

BAISC COGNITION

---

There are two types of cognitive processes: basic and higher. Basic cognition refers to capacities, such as attention, perception,  information, and memory. Attention is the action of selecting and focusing on stimuli in order to retain the information. The five senses are focused and used to interact with the environment around a person. One may use their eyesight and hearing  to learn during a psychology class, or smell and taste to pick up distinctive characteristics of a food. Perception is the processing of the information given by the five senses and through attention. The brain captures sensations and gives them meaning, associating something picked up to an item, idea, or a concept. This information is then compiled together  to create an organized space to access this information. This leads to the final type of basic cognitive process, memory. Stored information is retained within the system for later access. This varies from both short-term and long-term memory, depending on how the brain sorts the information. 

HIGHER-LEVEL CONGNITION

---

The second type of cognitive process is higher-level cognition. This involves actions, such as critical thinking, creativity, language, and learning. Thinking is the bringing together of information, leading to meaningful judgments and deductions. People can plan for their futures, make important decisions, and manage their behavior by using the previously stored information in new ways. Creativity is the development of new ideas based upon what is already in one’s system. When using previously accessible information, sometimes people begin to create their own path and use that information to develop more advanced  ideas or concepts. Language is the fundamental method for communication, and knowing how to speak a language is important for living life. In general, humans communicate with one another using speech, reading, and writing, though there are also gesture-based languages, such as sign language. Finally, learning is the process in which humans do everything in life. The taking in of information and using it in everyday life is something that we cannot live without and is an important cognitive process. 

However, there exists a number of biases that affect how people utilize cognitive processes, due to systematic errors that occur when shortcuts, or quick rules, are used when using cognitive processes.

When executing these actions, however, there exists a number of biases that affect how people utilize cognitive processes, due to systematic errors that occur when shortcuts, or quick rules, are used when using cognitive processes. These are known as cognitive biases. The most common five biases are anchoring bias, confirmation bias, negativity bias, actor-observer bias, and the halo effect.

Anchoring bias involves relying excessively on the initial information received when making decisions, even if it’s irrelevant or incorrect. People tend to go with their natural instinct and what is first presented to them. For instance, in shopping. If you see a shirt first retailing for $1,200 then see another shirt for $500, it is not uncommon for the second shirt to be viewed as cheap because in comparison to the first $1,200, it seems drastically cheaper. By first taking in the information of a shirt being $1,200 and internalizing that, and then seeing a $500 shirt, the expectations for the normal price of a shirt are shot up because you are anchored on the first price.

The second type of bias, confirmation bias, is the inclination to favor information that supports existing beliefs and values while disregarding contradictory information. Once again, humans can be considered very self-centered and assume that they are always correct. As a result, when looking into information on a topic with pre-existing knowledge, people tend to favor information and sources that agree with what they initially believed and fail to look at opposing arguments closely, if any at all. For example, when looking into new smartphones, there may be a pre-existing, strong bias for a certain brand of smartphone. When reading reviews, recommendations, and opinions, it is common to subconsciously pay more attention to positive information about that brand or product. This, in turn, clouds the true facts and leads to a stronger inclination to prefer an object or idea due to this pre-existing bias.

Negativity bias is the tendency to give more importance to negative information or experiences compared to positive ones. Negative events, emotions, or information is usually paid more attention to and often have a stronger impact on thoughts and behaviors. Memories, for instance, tend to be more vivid and clear with more negative experiences rather than positive ones. Humiliation, embarrassment, and anger are all recalled more vividly because of its negative qualities and stand out more as a result. News stations also use this to their advantage, opting to display more negative stories as it captures attention and keeps the audience engaged. Stories involving conflict, natural disasters, and bad news are focused on more as it keeps the audience watching and intrigued. 

The fourth type of bias, actor-observer bias, is the cognitive bias that refers to the tendency of people to attribute their own behavior to external factors that are out of their control. On the contrary, people often attribute others’ behaviors to their personality and other internal factors. For instance, in traffic, if you cut someone off, you might tell yourself that you were just in a hurry or you didn’t see the car. However, when someone else cuts you off, it is not uncommon for the reaction to be to blame the other person, to call them careless, reckless, and an aggressive driver. 

The horn and halo effect make up the fifth type of cognitive bias. The halo effect is where our overall positive impression of a person influences how we feel and think about other parts of their character. If we perceive someone positively in one aspect, we are more likely to have a positive impression of them as a whole, allowing the positive trait to "radiate" and create a favorable "halo" around the person. Conversely, the horn effect is the opposite, where an initial negative impression results in continuous negative views about that person. This bias can lead to judgments that are not entirely objective, as our perception is influenced by a single trait. The most common instance is with physical attractiveness. If we find a person especially appealing, we often presume other positive qualities, such as kindness and intelligence, but this may not always be the case. This bias is also the basis for the idea of “having a good first impression,” where the initial interaction with a person can either set up or ruin the way that the other person visualizes the rest of your character and you as a person.
