Childhood physical and cognitive development: General characteristics
- Unevenness, magical thought
From 2-6 years of age, children are starting to learn patterns of rational thinking, but they don’t do this rational thinking all of the time (thinking with reason). Rather, they overgeneralize the patterns of thinking that they do know.
Childhood physical and cognitive development: General characteristics example (uneveness and magical thought)
For example: from watching their parents cook, children figure out that when you boil something for long periods of time, it gets smaller/there should appear to be less in the pot.
- Researchers then put rocks in boiling water and they asked kids what they thought would happen. The kids said they believed that the rock in the boiling water would shrink. After showing the kids, they insisted that the rock shrunk. This represents overgeneralization and underspecification. So, during the age 2-6 years developmental period, we witness a patchwork of competent and incompetent thoughts/ a mixture of sound logic and magical thinking
Piaget 4 stages of cognitive development
- Sensorimotor (birth-2 years)
- preoperational (2-6 years)
- concrete operational (6-12 years)
- formal operational (12-19 years)
Sensorimotor stage of cognitive development
Sensorimotor (birth-2 years): thinking based on physical activity
Preoperational stage of cognitive development
Pre-operational (2-6 years): overcoming limitations to logical thinking by keeping all aspects of a problem in mind.
There is a focus on cross-domain problems, and children must figure out what variables in a problem/task matter. This overall thread of this stage is the challenge of keeping multiple perspectives in mind at once.
Concrete operational stage of cognitive development
Concrete operational (6-12 years): logical operations to combine, separate transform importation
This involves mastering the use of logic in concrete ways. The word concrete refers to that which is tangible; that which can be seen, touched, or experienced directly.
Formal operational stage of cognitive development
Formal operational (12-19 years): Systematic thinking about logical operations. Interest in abstract ideas and the act of thinking (metacognition = thinking about thinking). More interest in abstract ideas, and not bound to what is directly and explicitly right in front of them.
Three Functioning characteristics of preoperational thought
- Egocentrism
- Confusion of appearance and Reality
- Precausal reasoning
Three Operational characteristics of preoperational thought: Egocentrism
Egocentrism: difficulty in seeing the world from another’s perspective. Don’t take a spatial perspective (can’t break out of their own spatial perspective). Egocentric speech: gives too little information to listen to who cannot see objects.
Three Operational characteristics of preoperational thought: egocentrism and theory of mind/ false belief task
Egocentrism & Theory of mind/ false-belief taskTheory of mind and false-belief tasks: children are egocentric and lack theory of mind; they don’t understand that other people see the world differently than they do.
Theory of mind is that other people have minds; other people have their own mental states and intentions that are separate from and possibly different from one’s own.
Evidence comes from “The false belief” tasks: a young child is presented with a box of crayons and when it’s opened, he notices that the crayon box is filled with candy not crayons. The experimenter then asks the kid to describe what he thought would be in the box, the kid says that he thought the candy would be in the box. This shows that he doesn’t know that his own state of mind has changed. Then he is asked what other people would see in the box & he says candy.
A slightly older kid understands both that he initially thought crayons would be in the box and that another person would also think that crayons would be in the box.
Three Operational characteristics of preoperational thought: confusion of appearance and reality
In the preoperational period, children tend to focus on only a single dimension/feature (either height of a container but not width, spatial distribution but not number, etc.)
Specifically, they have a tendency to focus on just the surface attributes (the most salient/ notable features) of an object, ultimately causing them to confuse appearance with reality. For instance, in the Maynard cat experiment, if you put a dog mask on a cat, a process that a 3 year old sees happening, they think the cat is a dog. But at age 6, they know it’s a cat simply wearing a dog mask.
Three Operational characteristics of preoperational thought: precausal reasoning
In the preoperational period, children tend to confuse cause and effect. They don’t use induction (specific to general) or deduction (general to specific). Rather, they tend to use transductive reasoning, which involves them creating (inaccurate/erroneous) connections between particular instances. For example, many 3 year olds are afraid of graveyards. They know that they contain dead people, and so they believe that graveyards cause death, causing them to be scared of them. This represents transductive reasoning (confusing 2 facts).
Transductive reasoning: confusing 2 facts

Rather, they tend to use transductive reasoning, which involves them creating (inaccurate/erroneous) connections between particular instances.
Transductive reasoning: confusing 2 facts (graveyard and death)
Problems with Piaget’s view on cognitive development
Piaget emphasized domain-general mechanisms of cognitive development. The issues with this are the experience and language-dependence of tasks.
Overestimating the ability of adolescence and underestimating infant’s capacity.
Task-dependent performance: (experience-dependent nature of tasks)
Task-dependent performance: With regard to the experience-dependent nature of the tasks, an experimenter can make the task easier for children by using familiar objects, scenarios, etc. Additionally, the amount of exposure the kid has in setting up the surprising task matters, as well as whether or not it is presented to them as a trick. Moreover, a child’s performance on these tasks improves when the task is part of an ongoing activity that they already understand.
Linguistic nature of tasks:
Linguistic nature of the tasks: With regard to the language-dependent nature of the tasks, a child’s ability to distinguish between appearance and reality depends on how the question is asked and the context of the language (familiar vs. unfamiliar).
Domain general mechanisms in cognitive development: working memory, executive function, statistical learning:
The idea of domain-general approaches to cognitive development is that specific types of knowledge (physical laws, social behaviors, animacy) are all grounded in the same underlying mechanisms. Some examples include working memory, executive function, and pattern recognition/statistical learning. With domain general approaches, there is an emphasis on the similarity in performance (and errors) across domains.
Statistical Learning
Statistical learning in children is like how they pick up patterns from things they see and hear around them, without anyone needing to teach them directly. This helps them learn their language, like figuring out where words start and end when people talk, and understanding rules of how words fit together. They also notice patterns in other areas, like recognizing shapes, sounds, and even how people behave. It’s a natural way for kids to learn a lot just by being curious and paying attention to the world.
The biological mechanism that uses environmental input/information to actually drive language learning is a domain-general cognitive mechanism: statistical learning.
Domain-specific mechanisms to cognitive development: dedicated subsystems/modules
The idea of domain-specific approaches to cognitive development is that specific types of knowledge (physical laws, social behavior, animacy) require specific, specialized mechanisms.
Examples include special social niches/experiences and dedicated, experience-expectant biological subsystems (mental modules). With domain-specific approaches, there is an emphasis on the unevenness of performance and errors across domains.
Aspects of Domain-specific approaches: modularity/ core knowledge of physics (Spelk)
Core knowledge of physics, as discussed by Spelke, refers to the idea that even very young children, like three-year-olds, naturally understand some basic concepts of physics. For example, they know that if you change the shape of a substance (like clay or water), the substance itself is still there. Also, kids between the ages of two and six start to grasp ideas about inertia (objects keep moving unless something stops them) and gravity (things fall down, not up), and they get better at understanding these concepts as they grow and learn more from their surroundings.
This suggests that knowledge about basic physical principles is not just randomly acquired; it has a special importance, possibly because understanding these principles has been crucial for human survival and development through history.
Aspects of Domain-specific approaches: modularity/ TOM and autism
In simpler terms, research by Baron-Cohen has found that children with autism are really good at understanding and predicting patterns in things like puzzles or machines—often even better than kids without autism. However, they have a harder time understanding patterns that involve people’s thoughts and feelings. This suggests that autism affects a specific area of thinking skills that deals with social interactions, rather than all types of thinking skills. Essentially, kids with autism can handle mechanical tasks really well, but struggle more with tasks that require understanding social cues or other people’s emotions.
TOM and autism: domain general (Tager-flusberg):
Tager-Flusberg found that strong individual differnces exist in the ability of children with autism to pass TOM tasks, as well as that children with autism show deficits in non-social domains as well. Namely in executive functioning, inhibition and language. Tager-Flusberg’s research suggests that autism affects more than just social skills. While it’s true that many children with autism struggle with tasks that involve understanding others’ thoughts and feelings (known as “theory of mind” or ToM tasks), they also have difficulties in areas that don’t involve social interaction, like planning, controlling impulses, and language. These findings show that the challenges faced by children with autism are not limited to social situations but are more general.
This broader view of autism suggests that the core challenge is in anticipating what will happen next in any context, not just in social situations.
Connecting domain-general to domain-specific approaches: Theory Theory
The “theory theory” (Gopnik): serves to connect domain-general and domain-specific approaches.
The “theory theory” idea, suggested by Gopnik, is about how babies learn about the world. Gopnik believes that babies naturally pay more attention to moving things. This helps them notice and focus on important details around them. From these observations, babies start forming their own ideas or “theories” about how things work—like understanding that objects fall if you drop them. They then test these theories, just like scientists, to see if they are right.
This idea combines two things: the natural focus on certain things (like moving objects) and the ability to make guesses and check them. So, babies are both drawn to the right things to learn from and are actively trying to figure out the world through their own experiments.
Connecting domain-general to domain-specific approaches: Skeletal principles
Smith’s idea is that our brains start out with the potential to develop special areas that are really good at understanding different types of information, like language or music. These areas don’t start off fully formed but grow and get better over time. As we experience more of the world, our brains sort this information and help these special areas develop. This means that while we might be born with a natural focus on certain types of information, the detailed understanding and brain structures to handle them get built up as we learn and grow.
Connecting domain-general to domain-specific approaches: the “scientist in the crib”
The “scientist in the crib” : development consists of a rational process of hypothesis generation and testing: consists of a rational process of hypothesis generation and testing.
Connecting domain-specific attentional biases-Cognition
Domain-specific attentional biases-Cognition is inherently rational: development consists of hypothesis generation and testing the importance of play, exploration.
How domain-specificity might develop- experience on neural specialization (karmiloff-smith)
Effects of experience on neural specialization (Karmiloff-Smith): Smith posited that the brain contains modules of domain-specific computational circuity that produce a domain-specific understanding of the world. But this modularity, she maintained, develops over time, and structure in the input helps drive the development of specialized brain structures that are domain-specific. Thus, modularity doesn’t simply start out specific but rather develops.
How domain-specificity might develop: effects of stable cultural practices?
Effects of stable cultural practices:
Cultural events can create domain-specific understanding and, therefore, developmental unevenness by influencing the occurrence and frequency of events; the relationships among events; and the role of the child in events. For instance, there is a domain-specific understanding of objects across cultures based on cultural differences in parents allowing their infants to explore their world.
Vygotsky: zone of proximal development
Vygotsky: zone of proximal development:
Focused on how the world around the infant creates structured input that drives cognitive development, a concept he referred to as the zone of proximal development. Specifically, he focused on activities between infants and parents whereby infants are being guided in an age-appropriate way, largely through scaffolding (picture book reading). He recognized that cultural differences in opportunities for scaffolding can create unevenness in the development of domain-specific knowledge.
Differences between Piaget’s and Vygotsky’s assumptions about the infant/child
Piaget emphasized an independent learning acting on the world through trial and error and hypothesis. On the other hand, Vygotsky emphasized a socially dependent learner learning as a result of the way people structure cognitive challenges/ learning.
Neither is right or wrong; it just depends on the task to determine which approach is most appropriate (learning solidity vs. learning how to cross the street).
Childhood social and emotional development (moral development, sources of developmental change)
Development of right vs. wrong: moral development
In the process of moral development/ the right vs. wrong, there are multiple forces at work, both internal and external. On the one hand, kids have a lot of external role models around them on which they can model their own behavior (heteronomous morality). On the other hand, kids have a gradual emergence of an internal sense of rules of behavior (autonomous morality). Moreover, the forces that exist to drive moral development are both externally-imposed and internally-driven, and they both have different developmental trajectories. We tend to see heteronomous morality increase at around 3 years of age, and we tend to see an emergence of autonomous morality at around 6-7 years of age.
Heteronomous morality
kids have a lot of external role models around them that they can remodel their own behavior.
Autonomous morality
kids have a gradual emergence of an internal sense of rules of behavior.
Domains of inhibition (development of regulation and self-control)
Movement, emotions, choice, conclusions
Domains of inhibition characteristics
The mechanisms guiding the development of morality are all about regulation and self-control/inhibition. Regulation is the ability to inhibit impulses (self-control), balancing what you want to do with your own internalized set of standards for your behavior.
Domains of inhibition: Movement
Movement inhibition is about effortful control (like in Simon Says), as well as the delay of gratification.
Domains of inhibition: Emotions
Emotions: there are primary emotions primary: pain, anger, and joy, and secondary: shame, pride, and embarrassment.
Emotion inhibition is slow developing. 3 year olds getting dropped off at preschool for the first time aren’t good at inhibiting their emotions and will cry to mom, hold on to her, and resist leaving her side.
However as kids get older and are being dropped off at school on the first day, more often than not they run towards toys and away from mom. This represents a kids active regulatory inhibition strategy to distract themselves and inhibit their emotions to not cry. They adaptively have figured out that they need to get somewhere else away from their mom so as not to react in a big emotional way, and therefore distract themselves by going to the toys.
Domains of inhibition: Choice
Choice inhibition also involves the delay of gratification.
Domains of inhibition: conclusion
Conclusion inhibition involves how much data you think you need to collect before deciding on an answer for something (i.e. how systematic are you?). For instance, in a picture-matching task, the amount of caution involved in coming to a conclusion increases between 5-10 years of age. A 5 year old will take 8 seconds, while a 10 year old will take 17 seconds. Thus 10 year olds are more systematic in their conclusions of differences/ more cautious. This task also just gets easier over time. Note that males are significantly worse than females in these tasks studying inhibition of conclusions.
Delay of gratification task
In the video watched in class on the delay of the gratification task, a child puts their hands on the table and is shown an M&M in a little bowl by the experimenter being covered by a cup. The child is told by the experimenter that when a bell is rung, they can reach out for and eat the M&M. The kicker is that the period in which the child is shown the candy and the experimenter rings the bell gets longer and longer after each trial. Younger kids don’t wait for the bell to ring; rather, they instantly grab the candy without caring about the bell or rules they were just told. But the experimenter still carries out the experimental actions/rings the bell to show the kid that he would’ve been able to eat it eventually.
But as the kids grow, they are able to handle longer delays and show better inhibition. Also, girls tend to do better at the tasks than boys. There are strong differences in the ability to inhibit one’s emotions and delay gratification by both age and gender.
Development of emotion regulation strategies:
Emotion regulation strategies slowly develop over time. From birth to 2 years, the main emotion regulation strategies include thumb-sucking and rocking (self-stimulation).
From 2-6 years, the main emotion regulation strategies include avoiding/reducing emotional arousal by closing your eyes or turning away and using language.
Development of Aggression: 2 types
Instrumental and Hostile Aggression
Instrumental Aggression
Instrumental aggression: The goal is to obtain something (like a toy), not to hurt someone. But ultimately end up hurting someone in order to obtain what you want (toy), though this hurting is just instrumental to you getting something.
Hostile Aggression
Hostile aggression: The goal is to hurt someone (bullying, establishing dominance, social shunning, and exclusion).
Developmental changes in aggression
From 12-24 months, we see a rapid increase in instrumental aggression as kids develop more motor competence, as well as due to their developing sense of self.
From 24-36 months, we see an emergence of teasing as a function of enhanced language skills and enhanced TOM (knowledge that teasing will affect someone else).
From 3-6 years, we see a decrease in physical instrumental aggression due to developing language skills, but more of an emergence of hostile aggression as a function of emerging social networks.We also continue to see language aggression/ the use of language as a weapon.
Gender differences in aggressive behavior:
Hostile aggression is more prominent in boys than girls. Girls tend to do more teasing than boys and employ relationship aggression. These gender differences are largely related to the fact that girls have more cognitive sophistication and better TOM than boys.
Causes of aggression
Awards: if you’re a kid in a situation where your aggression is rewarded, your aggression rates are going to increase. It is important to recognize that aggression can be inadvertently and unintentionally rewarded by parents (parents giving negative attention to the aggressor is attention nonetheless).
Imitation: imitation of a role models behavior. Observing a lot of physical punishment, especially when combined with aprental anger, can teach kids very early on to be aggressive, as aggression is highly salient to kids. This fact was demonstrated in Bandeur’s experiment on social modelng of aggression.
In his experiment, children who were watching an adult model aggressive behavior toward a doll (hitting it, pushing it down, etc.) carried out aggressive behavior toward the doll when they were subsequently presented with it. Further these kids generalized the aggressive behavior that was modeled to them, devising new ways of hitting the doll.
Children in the control group, however, with no exposure to aggressive modeling did not exhibit novel forms of aggression towards the doll.
Aggression is easily picked by children when it is modeled to them.
Sources of individual differences in aggressive behavior:
individual differences in aggressiveness can be traced back to individual differences in emotion regulation/inhibition. Specifically, sources of individual differences in aggression can come from psychobiology, family environment, or cognitive style.
Sources of individual differences in aggressive behavior: Psychobiology
Psychobiology: Aggression is associated with increased levels of testosterone and decreased levels of serotonin. But it is important to note that hormones serve not only to regulate aggression, but they themselves are also regulated by aggression (bidirectional, two-way street where hormones both regulate aggression and are regulated by aggression).
The experiment shown in class there were two rooms. A lizard could enter one room in which it would be able to win a fight. A lizard could also enter another room in which it would either lose in a fight or in which nothing would happen (lizard would neither win nor lose).
Researchers found that the lizards developed a preference for the location/room in which they won the fight. But they also found that if they simply injected testosterone into the lizards, they developed the same preference, demonstrating that the lizards don’t need to win the fight, they just need to have testosterone to develop that sense of pride and satisfaction. (i.e. testosterone surge causes the rewarding feeling). At the same time, they found that winning the fight also causes a testosterone surge, which is inherently rewarding to the lizards (rewarding feeling causes the testosterone surge). This shows that testosterone can also be a consequence of aggression, not just a cause.
Another aspect of psychology and individual differences is that aggressive behavior exhibited by children as early as age 3 is highly significantly predictive of later aggressive behavior in adulthood, which speaks to the stability of aggressive behavior, as well as the persistence of aggressive behavior over developmental time.
Sources of individual differences in aggressive behavior: Family environment
Aggression is associated with low SES but correlated with higher parental stress. In other words, even though aggression is associated with low SES, if you control for parental stress levels, the aggression becomes much weaker and in some cases disappears. Therefore, a lot of aggressive behavior in children is correlated with the level of parental stress in the home/ family.
Sources of individual differences in aggressive behavior: cognitive style
Aggressive children are more likely to interpret others’ actions in negative ways, which ultimately leads to more aggressive responses. This demonstrates that there are real connections between emotional regulation capabilities, inhibition capabilities, and aggression.
Strategies for controlling aggression in children: Developing a hiearchy
Developing a hierarchy for a child reduces their overall levels/displays of aggression because hierarchy makes it so that there are fewer other kids around that the child needs to worry about in terms of who might be aggressive toward you, or who you can be aggressive toward. In this way, developing hierarchy allows aggressive behaviors to stabilize and reduce overall.
Strategies for controlling aggression in children: Venting feelings (catharsis)
Venting feelings (Catharsis) has often been associated with controlling aggression, though there is little evidence to support this.
Strategies for controlling aggression in children: Punishment
Punishing aggressive behavior (such as spanking) is effective only if the child identifies strongly with the punisher, if punishment is used consistently yet not frequently, and if the punishment is explained by the punisher (i.e. why it is being done/for what purposes and what the ultimate message to be received/lesson to be learned from the punishment is). Overall, though, parents who do a lot of punishment have kids who are more anxious, stressed, and aggressive, especially if the aforementioned parameters are not met.
Strategies for controlling aggression in children: Reward nonagressive behavior (selective attention)
Rewarding and reinforcing non-aggressive behavior is important in controlling attention. This can also involve selective attention, which can mean paying attention to the victim only so as not to accidentally reward the aggressive child and/or putting the aggressive kid in time out.
