Talk:Piaget's theory of cognitive development

message: Piaget is one of the most influential figures in the history of psychology.  His work not only revolutionized developmental psychology but also formed the foundation for the subsequent investigation in the area of the formation of intellect.
Piaget's Stages of Cognitive Development
1. Sensori-Motor 0-2 years
2. Preoperational 2-7 years
3. Concrete operations 7-12 years
4.  Formal Operations 12 and up
I am currently in a development class, so this is exciting for me! This information added to the article is very helpful and I believe it helps the readers know exactly what the specific ages are for every stage. Rlilymm (talk) 03:01, 21 January 2021 (UTC)

message: It says in Classification: "A child is no longer subject to the illogical limitations of animism (the belief that all objects are animals and therefore have feelings)" and then later it says in Animism: "The child believes that inanimate objects have "lifelike" qualities and are capable of action. Example, a child plays with a doll and treats it like a real person. In a way this is like using their imagination", so basically it says that it doesn't happen, and then it says it does. How stupid.

message: ...but just eyeballing this, it looks like a few things may need addressing, at least in the preoperational area.
Egocentrism has at least two usage errors.  
"Animism" is awkwardly written; among other problems, use of "their" as a gender-neutral singular pronoun isn't respectable English.  Also, the final statement in that section hardly seems to need to be there, from a "quality of article" perspective.
Finally, there's no mention of transductive thought.
Not meaning to cast any stones here; you all do a great job, and if I had more time/ability, I'd try to get on board myself.
For that matter, I'm not entirely sure if I'm paying proper attention to the talk page guidelines; but I have a session to teach in a few moments, and if I don't point it out now, I may not remember to later.  Apologies, if so.

thread_title:   even if they think incorrectly? 

message: The stages of reasoning Piaget describes are not his theory of cognitive development, more properly named as Piaget did, cognitive equilibration.  The stages are evidence of development in a person's reasoning.  His description of the stages is an effort to describe patterns in the vast volume of data he and his colleagues collected.  To leave out assimilation, accommodation, self-regulation and equilibration is to leave out Piaget's theory of cognitive equilibration.  
A foundation of the theory is a fundamentally different view of the nature of knowledge.  Because the nature of knowledge in Piaget's work is not a realist view of the nature of knowledge, Piaget's descriptions of the stages of reasoning and his theory of cognitive equilibration are essentially not capable of being understood from the realist point of view.  (Check out the second quote on the Piaget page in Wikiquote.)
Because Piaget was a genetic epistemologist, he was essentially an experimental philosopher.  To label him a developmental psychologist is to mislead the reader concerning Piaget.  As an experimental philosopher the focus of his attention was on the origins and development of knowledge in human beings.  —Preceding unsigned comment added by 67.41.40.69 (talk) 21:19, 14 May 2009 (UTC)

message: Sensorimotor Stage
Symbolic Functioning/Object Permanence Tasks
Piaget held that the highlight of the sixth Substage in the Sensorimotor period is the acquisition and development of symbolic function (Bjorklund, 169). Following this newfound ability, the child can then transition into the second Stage of Cognitive Development: The Preoperational Stage. To determine whether the child has achieved symbolic function, or object permanence, Piaget developed multiple experiments to gauge the child’s development. Piaget defines object permanence as an object which continues to exist in an individual’s mind, even though it is outside of their sight (Piaget, 4). Acquiring the sense of object permanence is one of the infant's most important accomplishments, according to Piaget.
Simple Hiding Task
To test the child, Piaget used an experiment in which the child is tantalized by some object (such as a toy), and then the object is hidden behind a napkin. During the first four months of the child’s life, there is little to no effort made by the infant to find the object under the napkin. After the first year, however, the child begins to search for the hidden item (Piaget, 4). Once the child is able to successfully and deliberately complete the simple hiding task by locating the object under the napkin, another task, the A-not-B search, is utilized.
A-not-B Search or Invisible Displacement Task
In the A-not-B search, a desired object is hidden beneath a napkin, just like the Simple Hiding Task; however, once the child sees the object disappear, the experimenter visibly removes the object and places it beneath a second napkin. Amazingly, the child still looks beneath the first napkin even though he saw it change locations. This is an indication that object permanence has not fully developed (Bjorklund, 138). This is what Piaget labeled the “Invisible Displacement Task” (Bjorklund, 138).
Piaget found a way to observe the child’s level of object permanence after the first year was to transitioning an object from a place visible to the infants view, to behind an object, and then to the other side where the child can see it again. Piaget states that “there is a stage when, at the moment the child sees the watch disappear at the left, he immediately turns back to the right and looks for the watch there. In other words, he looks for the object where he has found it before” (4). Object permanence can not only be monitored through this particular exercise, but also conditioned through its repetition (provided the child possesses the developmental capacity for object permanence). Through this mode of experimentation with the child, it becomes clear that the child is now aware of objects as things that can exist and move beyond his own intent and action (Maier, 116). For Piaget, the expected age during which a child must be able to complete the invisible displacement problems is between 18-24 months (Bjorklund, 139). After achieving this cognitive milestone, according to Piaget, the child transitions into the second phase of cognitive development: the Preoperational Stage.

message: Sensorimotor Stage:
According  to Piaget, the sensorimotor stage starts at birth, and it lasts until 2 years of age. During this stage children’s intelligence is limited to their own actions (Bjorklund, 2012). Children use sensorimotor schemas in infancy. Schemas are knowledge structures in which children represent knowledge (Piaget, 2000). There are six substages to the sensorimotor stage:
1. Basic Reflexes Stage
The first substage is the basic reflexes stage (from birth to 1 month), in which infants use their reflexes that they were born with to interpret their experiences (Bjorklund, 2012). These reflexes include sucking, grasping, eye movements, etc. 
2. Primary Circular Reactions Stage
The second substage is the primary circular reactions stage (from 1 to 4 months) in which the infant starts to do repetitive actions that are based on reflexes, such as voluntarily sucking on their thumb (Bjorklund, 2012). The infant may have randomly sucked on their thumb once and then wanted to recreate the experience and eventually would be able to suck their thumb whenever they pleased. 
3. Secondary Circular Reactions Stage
The third substage is the secondary circular reactions stage (from 4 to 8 months) in which the infant requires their first adaption of new behaviors. A major difference between primary and secondary circular reactions is that the interesting events are based on reflexes in the primary, and in the secondary the interesting events are found in the external world, such as objects and other people (Bjorklund, 2012). For example, if an infant while throwing a  tantrum and waving their arms and legs around hits a toy ball nearby and causes it to roll away across the room then they will become fascinated with the ball rolling away and they will learn to do it again and learn to make the ball roll. 
4. Coordination of the Secondary Circular Reactions Stage
The fourth substage is the coordination of the secondary circular reactions (from 8-12 months) in which the infant first beings to have goal-directed behavior. Piaget suggested that one of the most simplest coordinations is the infant moving an obstacle out of the way so that it could retrieve a visible object (Bjorklund, 2012). The infant wanted an object but something was in the way, so the infant moved what was in the way so they could get to the object that they wanted. 
5. Tertiary Circular Reactions Stage
The fifth substage is the tertiary circular reactions (from 12-18 months) in which the infant can make subtle alterations in their existing schemes that are directly related to solving a problem. An infant in this stage can solve problems using trial-and-error processes. According to Piaget, the infants intelligence is still limited to physical actions on objects in this stage (Bjorklund, 2012). 
6. Invention of New Means Through Mental Combinations
The sixth substage is the Invention of new means through mental combinations (from 18-24 months) in which the infant shows their first sign on mental representation (Bjorklund, 2012). Mental representation is being able to think about objects without directly acting on them. Also, the infant developed symbolic function by this time, which is expressed by language, deferred imitation, gestures, symbolic play, and mental imagery. 
The milestone for the sensorimotor stage would be object permanence. A milestone is when a child undergoes a major development or change. Object permanence develops during the last substage and it is the knowledge that objects continue to exist when they are not currently in view (Russell, 1999).

message: The article is quoted by operationalizing deductive logic as "using a general principle to predict the outcome of a specific event".  In every sense of the word, this is false.  The definition they gave has nothing to do with the induction/deduction distinction, and both types of arguments are able to use general principles to make specific predictions.  The true definition of deduction is that a deductive argument is intended to use logical means to prove the conclusion using the premises.  Conversely, induction aims to show the probability or plausibility of the conclusion using the premises.  When this article states that "children [in the concrete operational stage] at this age have difficulty using deductive logic", it is completely unknown if this is a true statement because the article fails to accurately describe deductive logic.  This is a critical error in the article and should be corrected as soon as possible by someone more knowledgeable in developmental psychology than me.

message: This new section in good faith (Neo-Piagetian physical microstructure for schemes and schemata) appears to be largely speculative, with only one relevant citation, referencing work which may not have been peer reviewed. 
The speculative nature is in the use of such phrases as ‘Piaget tentatively hinted’ (no citation or quotation); ‘ample ncRNA perhaps acting in their own right…’; ‘a seemingly plausible mechanistic framework’; ’it remains to be seen whether this will be consistent with new direct experimental evidence (if indeed such experiments are possible)’.
Also the citations need proper formatting ,and the use of an exclamation mark is not encyclopaedic.
Unless the entry can be improved and better supported by relevant citations of sources, I believe it should be deleted.
