Several beliefs, taken together, form the family of perspectives that contribute to this particular view. This is not a unique personal history, rather it is a story shared by many members of Henrys cohort. It describes cognitive development through four distinct stages: sensorimotor, preoperational, concrete, and formal. By 3 years old, high-income children knew almost double the number of words known by their low-income counterparts, and they had heard an estimated total of 30 million more words than the low-income counterparts (Hart & Risley, 2003). When John Watson wrote the book Psychological Care of Infant and Child in 1928, he sought to add clarification surrounding behaviorists views on child care and development. When all influences are considered together, itprovides a broader explanation of an adolescents development. Many diverse patterns of change, such as direction, timing, and order, can vary among individuals and affect the ways in which they develop. Cohorts share histories and contexts for living. For example, several contemporary studies support a model of development that is more continuous than Piaget's discrete stages (Courage & Howe, 2002; Siegler, 2005, 2006). The environmental factors, health and education, have been suggested by Neiss and Rowe to have as much effect on intelligence as inherited intelligence. It spans across several fields. 1. Glen Elder theorized the life course as based on five key principles: life-span development, human agency, historical time and geographic place, timing of decisions, and linked lives. In his view, children construct their knowledge through processes of assimilation, in which they evaluate and try to understand new information, based on their existing knowledge of the world, and accommodation, in which they expand and modify their cognitive structures based on new experiences. Inversely, the ability for adolescents to engage in spontaneous activity and creativity, both domains commonly associated with impulse behavior, decrease over the adolescent period in response to changes in cognition. Socioeconomic status is a way to identify families and households based on their shared levels of education, income, and occupation. And the 46-year old may have acquaintances, but rely more on family members to do things with and confide in. It can take complex, interconnected issues and narrow them down to the essentials. His book became highly criticized but was still influential in promoting more research into early childhood behavior and development. Scholars have noted that this lack of effective regulation often results in children engaging in behaviors without fully considering the consequences of their actions. The current view reflects the possibility that specific changes in development can occur later in life, without having been established at birth. Peers become more important for adolescents, who are exploring new roles and forming their own identities. By multidimensionality, Baltes is referring to the fact that a complex interplay of factors influence development across the lifespan, including biological, cognitive, and socioemotional changes. We tend to believe that our own cultures practices and expectations are the right ones. Keep in mind that theories are not facts; they are guidelines for investigation and practice, and they gain credibility through research that fails to disprove them. The dimensions of cognitive decline are partially reversible, however, because the brain retains the lifelong capacity for plasticity and reorganization of cortical tissue. I do not know about five principles of development, I can only offer a layman's view. We move through significant physical, cognitive, and psychosocial changes throughout our livesdo these changes happen in a systematic way, and to everyone? Source: Paul Baltes, as cited in Santrock (2002) f PRINCIPLES OF CHILD DEVELOPMENT Both, but mostly continuous as an individual learns and progresses, Many courses; there are variations between individuals and cultures, Both; development is influenced bybiological preparation and social experiences. In this way, this course covers and crosses multiple disciplines, such as psychology, biology, sociology, anthropology, education, nutrition, economics, and healthcare. In this module, well examine these questions and learn about the major stages of development and what kind of developmental tasks and transitions we might expect along the way. Proponents of the life-span. Without visual input, blind humans have demonstrated that tactile and auditory functions still fully develop and they can use tactile and auditory cues to perceive the world around them. This belief that our own culture is superior is calledethnocentrismand is a normal by-product of growing up in a culture. In the book, he warned against the inevitable dangers of a mother providing too much love and affection. Similarly, Elder showed that the Great Depression was a setting that significantly affected the development of adolescents and their corresponding adult personalities, by showing a similar common personality development across age groups. Likewise, whether or not development is best viewed as occurring in stages or rather as a gradual and cumulative process of change has traditionally been up for debate a question of continuity versus discontinuity. People of all ages offer words of wisdom to their younger counterparts in this WireTap video, from CBC Radio One. It included highly rewarding novel tasks that required attention control and became progressively more difficult to perform. 5.Development involves growth, maintenance and regulation. Henry shares many normative age-graded influences with his peers, such as entering the workforce at the same time, or having kids around the same age, but also normative history-graded experiences such as living through the Vietnam War and the Cold War. Watch this video from Big Brothers Big Sisters of America to learn more about the power of mentoring. Early Development is essential for later development. Low-income children perform significantly more poorly than their middle- and high-income peers on a number of educational variables: They have significantly lower standardized test scores, graduation rates, and college entrance rates, and they have much higher school dropout rates. At the University of Chicago, experts are working with low-income families, visiting them at their homes, and encouraging them to speak more to their children on a daily and hourly basis. In lifespan development, we need to rely on a systematic approach to understanding behavior, based on observable events and the scientific method. Learning occurs in a social context; considering the relationship between the environment and a persons behavior. One principle is physical growth and taking care of your body. Lifespan Perspective. In this research, low-income children made significant gains in their language development, likely as a result of attending the specialized preschool (Schechter & Byeb, 2007). Baltes states that the development of a particular domain does not occur in a strictly linear fashion but that development of certain traits can be characterized as having the capacity for both an increase and decrease in efficacy over the course of an individuals life. According to the process of selective optimization, individuals prioritize particular functions above others, reducing the adaptive capacity of particulars for specialization and improved efficacy of other modalities. As adolescents gain the ability to effectively regulate their actions, they may be forced to sacrifice other features to selectively optimize their reactions. Development is Children collecting rubber for wartime salvage. This approach is based on several key principles: Lifelong developmentmeans that development is not completedin infancy or childhood or at any specific age; it encompasses the entire lifespan, from conception to death. Similarly, Elder showed that the Great Depression was a setting that significantly affected the development of adolescents and their corresponding adult personalities, by showing a similar common personality development across age groups. Plasticity denotes intrapersonal variability and focuses heavily on the potentials and limits of the nature of human development. The notion of plasticity emphasizes that there are many possible developmental outcomes and that the nature of human development is much more open and pluralistic than originally implied by traditional views; there is no single pathway that must be taken in an individuals development across the lifespan. Baltes theory also states that the historical socio-cultural setting had an effect on the development of an individuals intelligence. For example, the religious teachings and traditions of a family may create a climate that makes the family feel stigmatized and this indirectly impacts the childs view of themselves and others. One experiment designed by Rder and colleagues (1999) compared the auditory localization skills of people who are blind with people who are sighted by having participants locate sounds presented either centrally or peripherally (lateral) to them. During childhood, individuals have difficulty effectively regulating their actions and impulsive behaviors. This chapter will briefly describe the seven major theoretical perspectives or theories on human development: . Their nutritional needs are different, and their primary psychological concerns are also distinctive. Development is Gradual 3. The areas of influence that Baltes thought most important to the development of intelligence were health, education, and work. This relation between developmental gains and losses occurs in a direction to selectively optimize particular capacities. Another psychologist who recognized the importance of the environment on development was American psychologist, Urie Bronfenbrenner (1917-2005), who formulated the ecological systems theory to explain how the inherent qualities of a child and their environment interact to influence how they will grow and develop. In addition, lifespan development can be divided into four levels depicting advanced functionality and character changes as an individual moves from one level to another. Lifespan developmentinvolves the exploration of biological, cognitive, and psychosocial changes and constancies that occur throughout the entire course of life. No single age period is more crucial, characterizes, or dominates human development. There are also emotional and social changes involving regulating emotions, interacting with peers, and possibly dating. Positive youth development in the united states: Research findings on evaluations of positive youth development programs. A theory about how people come to gradually acquire, construct, and use knowledge and information. Urie Bronfenbrenners theory stressing the importance of studying a child in the context of multiple environments, or ecological systems. As Henry grows up and has a family of his own, he is motivated by images of success tied to his past experience: he views a successful man as one who can provide for his family financially, who has a wife who stays at home and cares for the children, and children who are respectful but enjoy the luxury of days filled with school and play without having to consider the burdens of societys struggles. These could include milestones like earning a masters degree or getting a certain job offer or other events like going through a divorce or coping with the death of a child.

What else would you want them to know about you, your development, and your experiences to really understand you? Perhaps you have three: childhood, adulthood, and old age. In essence, lifespan theories explain observable events in a meaningful way. Baltes wrote that these three influences operate throughout the life course, their effects accumulate with time, and, as a dynamic package, they are responsible for how lives develop. In what ways have you changed? Can you identify it? He believed that all behaviors are learned, or conditioned, as evidenced by his famous Little Albert study, in which he conditioned an infant to fear a white rat. In this course, we will strive tolearn about each phase of human development and the physical, cognitive, and psychosocial changes, all the while making cross-cultural and historical comparisons and connections to the world around us. Development Proceeds from General to Specific 6. The table below reviews how each of these major theories approaches each of these issues. Neuronal changes to the limbic system and prefrontal cortex of the brain, whichbegin in puberty lead to the development of self-regulation, and the ability to consider the consequences of ones actions (though recent brain research reveals that this connection will continue to develop into early adulthood). With this type of development, there is a gradual change. Cultureis often referred to as a blueprint or guideline shared by a group of people that specifies how to live. In one longitudinal study, they found that although all the parents in the study engaged and interacted with their children, middle- and high-income parents interacted with their children differently than low-income parents. Are important aspects of development missing and if so, are they common for most of your cohort or unique to you? It seeks to understand how our personalities and traits are the product of our genetic makeup and biological factors, and how they are shaped by our environment, including our parents, peers, and culture. Undesired development or behaviors could potentially be prevented or changed. Other assumptions of a life-span perspective include: The aging process is multidirectional and involves both losses and gains. Lifespan theorists believe that development is life-long, and change is apparent across the lifespan. Psychologists, sociologists, neuroscientists, anthropologists, educators, economists, historians, medical researchers, and others may all be interested and involved in research related to the normative age-graded, normative history-graded, and nonnormative influences that help shape development. Most Traits are Correlated in Development and Others. Watson was the founder of the field of behaviorism, which emphasized the role of nurture, or the environment, in human development. Historic contexts shape our life choices and motivations as well as our eventual assessments of success or failure during the course of our existence. In what ways have you remained the same? Physical Domain Erik Erikson presented a model emphasizing the challenges and tasks presented across one's lifespan as key to understanding . Development is Continuous 2. Because most of us enter into a close relationship at some point, it is useful to know what psychologists have learned about the principles of liking and loving. This has been exemplified in numerous studies, including Nesselroade and Baltes, showing that the level and direction of change in adolescent personality development was influenced as strongly by the socio-cultural settings at the time (in this case, the Vietnam War) as age-related factors. Consider two very different cultural responses to menstruation in young girls. Over the course of puberty, neuronal changes modify this unregulated behavior by increasing the ability to regulate emotions and impulses. we need to rely on a systematic approach to understanding behavior, based on observable events and the scientific method. Research suggests that these achievement gaps are strongly influenced by differences in socioeconomic factors that exist among the families of these children. As you can see, our development is influenced by multiple contexts, so the timing of basic motor functions may vary across cultures. We will explore this idea further in our discussion of psychosexual development, but first, we must identify the parts of the self in Freuds model, or in other words, what constitutes a persons personality and makes us who we are. For example, individuals may sacrifice their capacity to be spontaneous or creative if they are constantly required to make thoughtful decisions and regulate their emotions. Sternberg describes contextual intelligence as the ability to understand what is called for in a situation (Sternberg, 1996). Childhood 6. Behavior is motivated by inner forces, memories, and conflicts that are generally beyond peoples awareness and control. As an example, recently researchers have been analyzing how other senses compensate for the loss of vision in blind individuals. Development is multidimensional, meaning it involves the dynamic interaction of factors like physical, emotional, and psychosocial development Development is multidirectional and results in gains and losses throughout life This training program focused intensively on aural language reception accuracy and cognitively demanding exercises that have been proven to partially reverse the age-related losses in memory. Other developmental theories focus on growth that happens throughout the lifespan, such as Eriksons theory of psychosocial development. 4. Vygotskys theory that emphasizes how cognitive development proceeds as a result of social interactions between members of a culture. Baltes, P. (1987). It is based on the idea that humans process the information they receive, rather than merely respond to stimuli. These findings suggest that when vision is absent in development, the auditory cortices in the brain recruit areas that are normally devoted to vision, thus becoming further refined. Finally, the work of Darwin, the British biologist famous for his theory of evolution, led others to suggest that development proceeds through evolutionary recapitulation, with many human behaviors having their origins in successful adaptations in the past. In Baltes theory, the paradigm of contextualism refers to the idea that three systems of biological and environmental influences work together to influence development. Rate of Development Varies Person to Person 5. The key here is to understand that behaviors, motivations, emotions, and choices are all part of a biggerpicture. Watch this video from Big Brothers Big Sisters of America to learn more about the power of mentoring. Watson explained that love, along with everything else as the behaviorist saw the world, is conditioned. Adolescents may also be forced to sacrifice their fast reaction times toward processing stimuli in favor of being able to fully consider the consequences of their actions. For example,Eriksonstheory that teenagers struggle with identity assumes that all teenagers live in a society in which they have many options and must make an individual choiceabout their future.
