Preoperational Intelligence Definition Essay

Development Psychology: Child In The Preoperational Stage

A study was carried out by two third year psychology students to investigate Piaget's stage theory. A 4 years old female child was tested in task of comprehension of more and less, followed standard and modified versions of conservation and class inclusion tasks. Results indicated that child exhibited difficulties in both modified conservation and class inclusion tasks despite the removal of some confounds in standard tasks. This infers that children of pre-operational stage do lack the ability to conserve and categorize objects, as predicted by Piaget. Further research need to address children's numerical abilities, as well as attending to perceptive seductions. This research needs to compare children who are able and unable to attend to number logics, as well as modifying the class inclusion task so that perceptive seduction cannot take place.

Child in the preoperational stageMany researchers have been interested in various confounds which are present in Jean Piaget's stage theories. His studies have postulated that children in the pre-operational stage lack the ability to perform conservation and class inclusion tasks (White, Hayes, Livsey, 2005). The methodologies of the study however, have been criticized by many researchers. Flaws and alternatives found in the standard Piagetian tasks include conversational confusions, perceptual seduction, and linguistic misunderstandings (Light, 1986, Siegel, 1978, 2003, Meadows, 1988). These issues have been addressed with modifications to the standard tasks. Majority of the research have found modified tasks to be better predictors of child's abilities in conservation and class inclusion tasks. (Light, 1986, Siegel, 1978, 2003, Meadows, 1988).

According to Piaget's stage theory, children in the pre-operational stage are non-conservers (White et al, 2005). Their tendency of centration causes them to focus on only one aspect of the problem at a time (White et al, 2005). This implies that they are unable to comprehend that quantitative properties of certain objects remain unchanged despite changes in its appearance (White et al, 2005). For example, pre-operational children typically judge water of the same volume to be more, after the transformation in standard liquid conservation tasks (Siegal, 2003). A problem in this procedure however, lies within the confusion caused by children's conversational experience (Siegal, 2003). This theory proposes that rather than actually responding to the logic behind the transformations of the liquid, children misinterprets the repetition of the same question as a cue to switch their answer in order to please the adult experimenter (Siegel, 2003).

To address conversational confusion, liquid conservation tasks had been modified by the means of incidental transformation (Light, 1986). The intention of this modification is to contextualize the intentions of adults in repeating...

Definition of Intelligence

"Intelligence is an adaptation…To say that intelligence is a particular instance of biological adaptation is thus to suppose that it is essentially an organization and that its function is to structure the universe just as the organism structures its immediate environment" (Piaget, 1963, pp. 3-4).

"Intelligence is assimilation to the extent that it incorporates all the given data of experience within its framework…There can be no doubt either, that mental life is also accommodation to the environment. Assimilation can never be pure because by incorporating new elements into its earlier schemata the intelligence constantly modifies the latter in order to adjust them to new elements" (Piaget, 1963, p. 6-7).

Ideas and Interests

Jean Piaget was a precocious child who demonstrated a keen interest in animal life and an encyclopedic knowledge of biology and taxonomy. When he was ten years old, he began volunteering at the Neuchâtel Museum of Natural History. The museum's director, the seventy year-old naturalist Paul Godet, took him on as his assistant and apprentice, and paid him for his work by giving him rare specimens for his personal collection (Vidal, 1994). Piaget continued to work at the museum for four years, and his interest in the natural sciences continued to grow. His professional accomplishments in this area were numerous, beginning at age ten when he published a paper on the albino sparrow, and culminating with a doctoral thesis on the classification of mollusks when he was twenty-one.

After completing his Ph.D., Piaget spent several months studying psychoanalysis at the University of Zurich. He was a promising student, and his contemporaries believed that he would eventually make important contributions to this field (Vidal, 1994). However, a serendipitous opportunity presented itself, and Piaget soon found himself working for Théodore Simon, co-author of the Binet-Simon intelligence scale. Simon placed him in Binet's laboratory, and set him to work standardizing Cyril Burt's reasoning tests on Parisian children.

Piaget thought that the standardizing task was dull, and he never finished it. However, his clinical interactions with the children were not without interest. He began to notice that children of similar ages made similar types of mistakes, and it occurred to him that Simon, Binet and Burt might be asking the wrong question: Perhaps the key to understanding human intellectual development is not in what children get wrong, but how they get it wrong. It was clear to Piaget that childish reasoning is not merely less accurate than adult reasoning; it is qualitatively different (Wadsworth 1996). From this point forward, Piaget dedicated himself to answering the question "How does knowledge grow?"

Piaget eventually came to believe that intelligence is a form of adaptation, wherein knowledge is constructed by each individual through the two complementary processes of assimilation and accommodation. He theorized that as children interact with their physical and social environments, they organize information into groups of interrelated ideas called "schemes". When children encounter something new, they must either assimilate it into an existing scheme or create an entirely new scheme to deal with it (Wadsworth 1996).

Piaget also believed that intellectual development occurs in four distinct stages. The sensorimotor stage begins at birth, and lasts until the child is approximately two years old. At this stage, the child cannot form mental representations of objects that are outside his immediate view, so his intelligence develops through his motor interactions with his environment. The preoperational stage typically lasts until the child is 6 or 7. According to Piaget, this is the stage where true "thought" emerges. Preoperational children are able to make mental representations of unseen objects, but they cannot use deductive reasoning. The concrete operations stage follows, and lasts until the child is 11 or 12. Concrete operational children are able to use deductive reasoning, demonstrate conservation of number, and can differentiate their perspective from that of other people. Formal operations is the final stage. Its most salient feature is the ability to think abstractly.

A central tenet of Piaget's Genetic Epistemology is that increasingly complex intellectual processes are built on the primitive foundations laid in earlier stages of development. An infant's physical explorations of his environment form the basis for the mental representations he develops as a preoperational child, and so on. Another important principle of Piaget's stage theory is that there are genetic constraints inherent in the human organism-You can challenge a child to confront new ideas, but you cannot necessarily "teach" him out of one stage and into another. Moreover, a child cannot build new, increasingly complex schemes without interacting with his environment; nature and nurture are inexorably linked. As Piaget put it:

Intelligence does not by any means appear at once derived from mental development, like a higher mechanism, and radically distinct from those which have preceded it. Intelligence presents, on the contrary, a remarkable continuity with the acquired or even inborn processes on which it depends and at the same time makes use of. (Piaget, 1963, p. 21)

Attempts have been made to correlate performance on Piagetian conservation tasks with standardized intelligence test scores, and the results have been mixed. (Kirk, 1977). Ultimately, an intelligence test built on a Piagetian framework would have to function very differently from intelligence tests like the Wechsler or the Stanford-Binet. In addition to recording a child's correct and incorrect responses, the test administrator would also have to ask the child to explain why he answered in a given way. Piaget suggested that one way to reconcile these two approaches would be to adopt a method clinique, whereby a traditional intelligence test could serve as the basis for a clinical interview (Elkind, 1969).
