Adaptive nature of cognitive immaturity A hypothesis of pre-perceptual multimodal integration explains an adaptive nature of cognitive development and converges two competing naturalist and constructivist viewpoints about cognition. According to the hypothesis, mental processes such as perception, attention, memory, and awareness begin with the association of affective cues with stimuli responsible for triggering the neuronal pathways of simple reflexes. Electromagnetic properties of the mother's heart and its interaction with the mother's own and fetal nervous system (physical laws of electromagnetic interference) form neuronal coherence in the mother-fetus bio-system, providing the template beginning from pregnancy.
Attention According to Professor
Wilhelm Wundt (1832-1920), physiologist and philosopher, attention is the concentration of awareness on some phenomenon during a period, which is necessary to elevate the clear
perception of the narrow region of the content of
consciousness and which is feasible to control this focus in
mind. Therefore, attention is a process of controlling thought that continues over time. His experiments showed that the size of the focal area of consciousness in adults ranges from three to six items. The empirical data has four stages: • The first stage, with up to two items in the focal point, lasts up to about six months of age. • The second stage, with up to three items, begins after eight months. • The third stage appears at about 3.5 years of age with four items. • The fourth stage starts in children when they are about five years old and can hold five or more items in the focal point. Research on the development of memory has indicated that declarative, or explicit memory, may exist in infants who are even younger than two years old. For example, newborns who are less than 3 days old demonstrate a preference for their mother's own voice.
Perception Attribution of causality The perception of causality was initially studied by professor Albert Michotte where he presented adults with animated images of moving balls. By manipulating the direction and timing of the moving balls (spatial and temporal dimensions) he was able to influence participants' perception of causality. There is contradicting evidence on whether causal perception is innate and present at birth or whether it is a result of perception development. Through research with very young infants, many studies have shown support for the theory that humans are born with the mechanisms needed for the perception of causality. Recent research has even shown this ability in newborns only a few hours old. However, other studies have shown similar results received by Michotte (1976) in infants as young as 6 months, but not younger. These studies support a more developmental progression of abilities required for the perception of causality.
Object permanence Object permanence is the understanding that an object continues to exist, even when one cannot see it or touch it. It is an important milestone in the stages of cognitive development for infants. Numerous tests regarding it have been done, usually involving a toy and a crude barrier which is placed in front of the toy, and then removed repeatedly (
peekaboo). In early
sensorimotor stages, the infant is completely unable to comprehend object permanence. Psychologist
Jean Piaget conducted experiments with infants which led him to conclude that this awareness was typically achieved at eight to nine months of age. Infants before this age are too young to understand object permanence, which explains why infants at this age do not cry when their mothers are gone – "Out of sight, out of mind". A lack of object permanence can lead to
A-not-B errors, where children look for an object at the location where they first discovered it rather than where they have just seen it placed.
Depth perception Studies in psychology also suggest that
three dimensionality and
depth perception is not necessarily fully
intuitive, and must be partially learned in infancy using an
unconscious inference. The acquisition of depth perception and its development in infant cognitive systems was researched by professor Richard D. Walk. Walk found that human infants can discriminate depth well from an "innate learned" point of view: they are able to discriminate depth from the age at which they can be tested. However, their visual mechanisms are still maturing. Walk discovered that infants are better able to discriminate depth when there is a definitive pattern separating the deeper and shallower areas than if either one is at all indefinite, and that the depth and distance must be of a certain level of distance in order to be successfully distinguished by the infant. According to Walk there is a clear development of perceptual behaviour, as with increasing age it is shown that children are able to discriminate between depths more accurately, and gauge more subtle differences between depths.
Physical laws Largely thanks to the innovative strategies developed by professor
Renee Baillargeon and her colleagues, significant insights have been developed regarding how young infants comprehend natural physical laws. Much of this research depends on carefully observing when infants react as if events are unexpected. For example, if an infant sees an object that appears to be suspended in mid-air, and behaves as if this is unexpected, then this suggests that the infant has an understanding that things usually fall if they are not supported. Baillargeon and her colleagues have contributed evidence, for example, about infants' understanding of object permanence and their reasoning about hidden objects.
Shared intentionality The noted above hypotheses plausibly explain
perception development when the nervous system of the young organism has already mastered the mode to distinguish relevant stimuli from the cacophony of electromagnetic waves, chemical interactions, and pressure fluctuations. The
Shared intentionality approach attempts to describe environmental learning in the previous developmental period (even before birth) when nothing is still known, and the young organism just learns how to assimilate basic common meanings. declared observed inter-brain activity under conditions without communication in pairs while subjects were solving the shared cognitive problem, and they registered an increased inter-brain activity in contrast to the condition when subjects solved a similar problem alone. These data show that collaborative interaction without sensory cues can emerge in mother-child dyads, providing Shared intentionality, which indicates to the immature organism the essential sensory stimulus of the actual cognitive problem.
Language From birth, babies are learning to communicate. The communication begins with crying and then begins to develop into cooing and babbling. Infants develop their speech by mimicking those around them. Gestures and facial expressions are all part of language development. In the first three months of life babies will generally use different crying types to express their different needs, as well as making other sounds such as cooing. They will begin mimicking facial expressions and smiling at the sight of familiar faces. Between the ages of 4–6 months infants have a greater response towards different tones in voices, and greater engagement, watching the speaker's face. The child's own language skills develop with larger variation in babbling sounds, and elicit responses in conversation through babbling. From 7 months to the end of their first year babies are able to understand frequently heard words and can respond to simple requests. Their babbling becomes more complex and they communicate with it as if they are making sense, they use babbling to express their desires. Non-verbal communication also develops and actions such as waving goodbye are produced. This is also the period in which babies often say their first word, an important milestone in the child's life. There are a number of theories as to how children acquire language, including the work of Skinner, who argued that language is learnt via reinforcement. Skinner argued that echoic verbal behavior is essential to child language acquisition. Parents reinforce language by responding with attention and correcting mistakes, promoting more accurate language development. Others argue that language acquisition is innate, such as
Chomsky. He argues that all babies are born with an innate language faculty helping them learn language naturally during infancy, later referred to as the LAD (Language Acquisition Device), acquiring language rapidly, without conscious access. This provides them with an inherent understanding of linguistic principles which allows them to learn and produce language, even with limited input from caregivers or the ability to hear speech. This allows humans to produce and understand an infinite number of novel sentences from a finite number of grammatical rules. He acknowledges that the environment acts as a trigger for pre-existing structures for language learning. involving the support and 'scaffolding' by caregivers. This involves correction of poor language, expanding vocabulary, modelling sentences, and prompting of speech.
Empathy Empathy involves the ability to recognize one's own and others feelings, and regulate emotional response accordingly. In the first few days of life, babies are able to discriminate distress cues by human voices and cry when other babies cry. From 3–7 months, infants can identify sad vocalizations and facial expressions. From 5–10 months, they show a preference for prosocial characters in shows, being aversive to harm caused by others. Children at 24 months are aware of their wrongdoing, and show shame-like responses from 29 months. Infants with a secure attachment, related to consistent parental care, appear to show more empathy. This suggests that empathy is not an automatically developed skill, but one that is activated based on experience.
Metacognition Self-awareness The most common technique used in research for testing self-awareness in infants is a mirror test known as the "
Rouge Test". The rouge test works by applying a dot on an infant's face and then placing them in front of the mirror. If the infant investigates the dot on their nose by touching it, they are thought to realize their own existence and have achieved self-awareness. A number of research studies have used this technique and shown self-awareness to develop between 15 and 24 months of age. Some researchers take language such as "I, me, my, etc." as an indicator of self-awareness. Rochat (2003) described a more in-depth developmental path in acquiring self-awareness through various stages. He described self-awareness as occurring in 5 stages beginning from birth.
Symbolic thought Symbolic thought refers to the ability to use words, images, and other symbols to represent words or feelings. During the preoperational stage a child's capacity for symbolism increases, this is shown by their increase in language use during this stage. This can also be seen by the way children play with objects, a stick becomes a sword and a box becomes armor. Children in this stage still might not understand that a map represents a real place, and that a picture of food does not have a smell.
Theory of mind Theory of mind refers to the ability to understand and predict what others are thinking and feeling, involving recognizing that others have different beliefs. First order theory of mind refers to one's ability to understand their own mental life, while second order theory of mind refers to one's ability to understand the mental lives of others. Infants show early signs of understanding belief-related situations. However, they are generally thought to possess implicit mentalization—fast, non-conscious, and non-verbal—rather than explicit mentalization, which is slower, conscious, verbal, and typically emerges around 4 years of age. Implicit mentalization includes, for example, the ability to recognize when a communicative partner has incorrect or incomplete information about a relevant aspect of the world. Multiple independent studies suggest that, in such situations, infants communicate more frequently and accurately to share their knowledge with others. However, infants do not consistently perform well on tasks that require them to predict others’ behavior based on false beliefs, as reflected in the difficulty of replicating some of these findings. Children with
Autism struggle with theory of mind, showing mindblindness, a difficulty understanding other people's thoughts and feelings, finding other individuals confusing and unpredictable. This is seen where autistic children show less pretend play and lower joint attention.
Executive function Executive function is a high-order cognitive ability, which allows you to sustain, switch and inhibit cognitive functions. It is involved in the processes of coordination, planning and goal-directed actions. Executive function emerges in the first year of life, and strengthens throughout childhood and adolescence. Cognitive abilities in infancy are predictive of executive functions at age 11, having long-term implications on memory and attention. == Cultural differences in development ==
