Mistrust Is the world a safe place or is it full of unpredictable events and accidents waiting to happen? Erikson's first psychosocial crisis occurs during the first year or so of life like Freud's oral stage of psychosexual development. The crisis is one of trust vs.
The development of memory in children becomes evident within the first 2 to 3 years of a child's life as they show considerable advances in declarative memory. This enhancement continues into adolescence with major developments in short term memoryworking memorylong term memory and autobiographical memory.
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.
Object permanence[ edit ] 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 stagesthe 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 errorswhere children look for an object at the location where they first discovered it rather than where they have just seen it placed.
Depth perception[ edit ] Studies in psychology  also suggest that three dimensionality and depth perception is not necessarily fully intuitiveand 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 Richard D. Walk found that human infants is able to 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 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. 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.
Language acquisition 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.Sep 12, · Erik Erikson: The History, Development, and Significance of His Work Erik Erikson has had a tremendous life and has left an amazing legacy.
He was an influential and pioneering psychologist, psychoanalyst, and author whose development of his psychosocial stages are immeasurable to the study of personalities.
Infant cognitive development is the study of how psychological processes involved in thinking and knowing develop in young children. Information is acquired in a number of ways including through sight, sound, touch, taste, smell and language, all of which require processing by our cognitive system.

A diagnosis of borderline personality disorder could, theoretically, mean that the psychiatrist made a serious attempt at evaluating defense mechanisms and ego integrity; or at least a matching of symptoms to DSM criteria.
It's theoretically possible, yes. The following literature review focuses on Erik Erikson's ideas as it critically analyses his psychosocial theory of human development by examining the eight stages of man, the key concepts within his theory, discussing the strengths, weaknesses and criticisms associated with his theory then concluding with the effectiveness of Erikson's theory in /5(16).
