Cognitive Development
Cognitive abilities make available a
way for us to handle the information that we receive from our senses. These
processing abilities include how we determine what our actions should be, how
we are able to compare one thing to another, remember past events, keeping what
we learn in memory, evaluate things and situations, and analyze information in
order to make decisions. There appears to be some instinctive element that is
present within our cognitive functioning. The strength of the heredity argument
is considered unsettled science at this time. However, Robert Plomin states,
"The evidence for a strong genetic contribution to general cognitive
ability is clearer than for any other area of psychology" (Davis, 2004). Genetics notwithstanding, most
of the research available considers cognitive ability to be a learned skill/s.
One of the key issues with cognitive
development is when it does not occur as it should within the individual. Most
development issues will have a direct impact on a person being able to learn,
and these issues more often than not will need to be addressed and acted upon
to help correct them to any degree. Cognitive functioning is not only
side-tracked through developmental issues, it can also be affected by physical
injury to the brain as well. No matter what the situation might be for an
individual cognitive functioning, when not up to speed, can in many cases be
brought closer to where it should be, and those with "normal"
functioning can be taken to higher levels of learning.
Childhood
Cognitive Development
Many opinions and much research has
been done in relation to cognitive development during the childhood years. Jean
Piaget (1896-1980) posited that children, "are actively involved in their
own cognitive development" (Jacobs, 2002).
Piaget's theory of cognitive development was based on the idea that, "the
mind, through its interaction with the environment, undergoes a series of
metamorphoses...as children grow their brains achieve new and more advanced
connections for different kinds of thinking" (Jacobs, 2002). Piaget's took his theory, based on assimilation and
accommodation and delineated it into stages. He referred to the childhood years
(from birth to 12 years old) as the sensorimotor stage, preoperational stage,
and concrete operational stage. His final stage, formal operations, applied to
those form 12 years old through adulthood. However, Piaget did not "corner
the market" on childhood cognitive development. Others would follow his
with ideas that were similar and that were somewhat contrary.
The social-cognitive perspective is
a type of hybrid approach to understanding childhood development that includes
cognitive functioning. In more recent times, "Albert Bandura and others
have demonstrated that much of what we know and do is acquired through the
process of observational learning" (Duffy
& Eastwood, 2005). What they mean here is that large portions of
what is learned throughout childhood in particular, and life in general, is
learned by watching other people model a behavior or activity without the
learner receiving any reinforcer at the time the activity is observed. This
makes the environment in which a child is raised a very important aspect of
their cognitive development. As they grow and use the knowledge acquired from observational
learning, the reinforcer not received at the point of learning will be present
at the time of acting of what was learned. The outcome can be good or bad based
on the information gathered during observation. One aspect of Bandura's idea is
that repeated exposure to, "violence in films, television, video games,
and other media not only desensitize us to violence but also induce violence in
children and adults" (Duffy & Eastwood,
2005). Thinking about how behavior patterns have seemingly disintegrated
over time should cause someone to pause after reading this last statement. How
true does it ring?
Adolescence
and Cognitive Development
Cognitive development as defined in
the opening portion of this paper could also be amended to include the ability
to think and reason. During the childhood years, the cognitive development
process (ability to think) becomes, as Piaget would say "concrete."
However, when adolescence is reached a more complex form of cognition begins
including reason, abstract thinking, and comparative thinking.
Cognitive change does not happen
overnight. The cognitive function changes that occur all along the lifespan
occur slowly, but never does it seem as slow, at least to the person in
process, than it does during the adolescent years (12-18 years old). The change
during these years, unlike Piaget's spurts of growth during childhood, is more
along the lines of the, "information-processing perspective (that) sees
changes in cognitive abilities as gradual transformations in the capacity to
take in, use, and store information" (Feldman,
2003). Education during these years is vital (assuming the educators are
proceeding properly) to cognitive growth. It is during these years that,
"people organize their thinking about the world, develop strategies for
dealing with new situations, sort facts, and achieve advances in memory
capacity and perceptual abilities" (Feldman,
2003). This information should make us keenly aware of the importance of
what a person is taught at this stage of life.
"Many developmentalists find middle schools to be developmentally regressive - they force children to step backward" (Berger, 2011). What does this mean in terms of cognitive development? "Long-term academic trajectories - the choice to stay in school or to drop out and the selection in high school of academic college-prep courses versus basic-level courses - are strongly influenced by experience in grades 6-8" (Berger, 2011). It should be accurate to suggest that this is the point of cognitive growth that the phenomena of evaluation apprehension (Cottrell) arises. Why is this important? Evaluation apprehension, "concern for how others are evaluating us" (Myers, 2010) can help or hurt a person's cognitive progress by altering how much effort they put forth to grow cognitively based on how they feel about being evaluated, and to some extent those evaluating them. This, in my opinion, is but one point of many as to why standardized testing is not good for most people during this stage of life or anytime for that matter.
While addressing the education aspect of cognitive development, omitting the technological component would leave out one of the most relative aspects of cognitive development at this stage of life. The internet, cell phones, and video games tend to eat away at the day. They are time-killers to put it mildly. There could be the usual discussion about how to properly use the internet, what is appropriate to send in a text message, and what video game rating is too explicit for someone of this age bracket. However, these things pale in comparison to two other sinister outcomes of using these tools and games. Sleep deprivation and addiction are concerns that all parents should have when it comes to using these mediums. The Mayo Clinic posted a report about adolescent sleep issues that is very pertinent to this discussion,
"Most teens need about nine hours of sleep a night — and sometimes more — to maintain optimal daytime alertness. But few teens actually get that much sleep regularly, thanks to factors such as part-time jobs, early-morning classes, homework, extracurricular activities, social demands, and use of computers and other electronic gadgets. More than 90 percent of teens in a recent study published in the Journal of School Health reported sleeping less than the recommended nine hours a night. In the same study, 10 percent of teens reported sleeping less than six hours a night.
"Many developmentalists find middle schools to be developmentally regressive - they force children to step backward" (Berger, 2011). What does this mean in terms of cognitive development?

Although
this might seem like no big deal, sleep deprivation can have serious consequences. Tired teens can find it
difficult to concentrate and learn, or even stay awake in class. Too little sleep also might contribute to mood
swings and behavioral problems. Another
major concern is drowsy driving, which can lead to serious — even deadly — accidents" (Mayo Clinic, 2011).
Lack of sleep can inhibit information intake that in turn can leave gaps in learning. The gaps can be stumbling blocks in the cognitive development future of the person who allows games to keep them from sleeping enough.
The other issue, addiction, can be just as, if not more, devastating in terms of cognitive development. Like sleep deprivation, "Addiction of any kind limits life experience, with the harm especially severe when the brain is still growing" (Berger, 2011). Does the brain grow throughout adolescence? It does continue to grow, and a quick glance at the physiological aspects of brain development reinforce the warning of Berger, "The final stage is synaptogenesis, or the formation of synapses. Although the process (brain growth) begins before birth, it continues throughout life as neurons form new synapses and discard old ones" (Kalat, 2009). With limits on life experiences and improper brain functioning (due to the fact the prefrontal cortex is not fully developed until a person is in their early 20s), it would make cognitive development much more difficult at best or non-existent at worse.
Leaving the negative side of adolescence, can there be healthy ways to address cognitive development? Robert J. Sternberg, in his resume that was posted on the Yale website recorded one of the best short descriptions of, not only his study of intelligence, but a great map to help understand how to maximize cognitive growth,
" My research is motivated primarily by a theory of successful intelligence, which attempts to account for the intellectual sources of individual differences that enable people to achieve success in their lives, given the socio-cultural context in which they live. Successfully intelligent people discern their strengths and weaknesses, and then figure out how to capitalize on their strengths, and to compensate for or remediate their weaknesses. Successfully intelligent individuals succeed in part because they achieve a functional balance among a "triarchy" of abilities: analytical abilities, which are used to analyze, evaluate, judge, compare and contrast; creative abilities, which are used to create, invent, discover, imagine; practical abilities, which are used to apply, utilize, implement, and activate. Successfully intelligent people are not necessarily high in all three of these abilities, but find a way effectively to exploit whatever pattern of abilities they may have. Moreover, all of these abilities can be further developed. A fundamental idea underlying this research is that conventional notions of intelligence and tests of intelligence miss important kinds of intellectual talent, and overweigh what are sometimes less important kinds of intellectual talent" (University of Oregon, 2001).
Sternberg is quite an intelligent man, and his contributions to the inner-workings of cognitive functioning are very helpful. His insights can help parents understand the role "true" intelligence plays in the life of their teenager, and from there the parents should be able to help foster cognitive growth in their teenager. Although intelligence and cognitive ability are not exactly the same, they are inter-related and inter-twined to the point that improvement in one should have a positive effect on the other. Cognitive ability can be, in most people, improved (fluidly) to a mature point (of crystallized intelligence). So, therefore a discussion of intelligence is relevant to the overall idea of this paper. So, in transition to adulthood, find the words of Sternberg from an audio transcript of an interview in which he "defines intelligence" in a most interesting way,
"I prefer to refer to it as "successful intelligence." And the reason is that the emphasis is on the use of your intelligence to achieve success in your life. So I define it as your skill in achieving whatever it is you want to attain in your life within your socio-cultural context-Meaning that people have different goals for themselves, and for some it's to get very good grades in school and to do well on tests, and for others it might be to become a very good basketball player or actress or musician. So, it's your skill in obtaining what you want in life within your socio-cultural context [which] means that if you want to be an axe murderer it wouldn't count--by capitalizing on your strengths and compensating for, or correcting, your weaknesses. And what that means is that people differ in their personal profiles. Some people are good at one thing; some are good at another thing. And if you look at people who attain success by their own standards, they're generally people who found something they do really well. And it can be very different things for different people. For some, it's doing well on IQ tests, or SATs. For others it might be playing basketball. For others it might be being a politician. So they capitalize on their strengths. And the things that they don't do so well-They find ways either to compensate, meaning that they perhaps have someone else do the things they don't do well, or they have them done by electronic means or whatever. Or correcting their weaknesses- They make themselves better at whatever it is they didn't do so well, by adapting to, shaping and selecting environments, which means that some of the time you change yourself to fit the environment. That's adaptation. So if you started a new job or a new relationship, part of the time you change yourself to fit the job or to fit the relationship. And shaping means that part of the time you change the environment that is. So you might try to modify the job to make it a better fit to you, or you might try to change the relationship to make it more what you hoped it would be. And selection means that sometimes you just get out. Being successfully intelligent means knowing when you're in the wrong place at the wrong time--the wrong job, the wrong relationship, the wrong place to live---Um, through a combination of analytical, creative and practical abilities. You need creative skills to come up with ideas; you need analytical abilities to know whether they're good ideas-to evaluate the ideas-and you need practical abilities to make your ideas work and to persuade other people that your ideas are worth listening to. So that's the definition" (Plucker, 2003).
Adult Cognitive Development
Emerging Adults
Often defined in terms of those who are ages 18-25 this period of life seems to have as much, if not more, in terms of cognitive development potential. This is also the beginning of the, "postformal thought" stage of life that, "originated because several developmentalists agreed that Piaget's fourth stage, formal operational thought, was inadequate to describe adult thinking" (Berger, 2011). However, when discussing cognitive development is there any real development? Do adults acquire "new" intellectual capabilities? The answer could be no. If that is the case then, "adulthood has no stages" (Berger, 2011). Maybe, maybe not?
Emerging adulthood reveals quite a bit of evidence for continued cognitive growth. One of the first things one might notice is the ability to combine the subjective with the objective. Subjectivity being emotionally driven based on the perceptions of life events, and objectivity being the way things really are (intellectual and logical in nature) sometimes need to be combined to make informed decisions in adulthood. "Without this consolidation of intellect and emotion, behavioral extremes...or cognitive extremes (such as believing that one is the best or the worst person on Earth) are common" (Berger, 2011).
The most important (as some consider it) cognitive advancement usually comes into play during this stage of life. The ability to, "consider a thesis and its antithesis simultaneously and arrive at a synthesis" (Berger, 2011) is called dialectical thought, and it is often considered the pinnacle of all cognitive development. There is one caveat to the synthesis arrived at employing this type of thought process, sometimes one should not strive to create a synthesis. Some things in life are separated into thesis/antithesis for a reason. Truth and non-truth cannot be synthesized into something that has objective meaning. If something is objectively true, it implies that anything opposite (antithetical) to it is false, and no amount of synthesis can blend the two. However, not to take the discussion too deep, if I say chocolate ice cream is the best, and you say vanilla ice cream is the best, I have formed a thesis and you have formed an antithesis. Who is right? Dialectical thought would enable us to agree that both are very good in spite of the fact that I prefer chocolate and you prefer vanilla.
There are other areas that come into play in emerging adult cognitive development. Gender differences tend to become clearer based on how each processes role ideas. Faith also becomes something to struggle with during this time for many people.
Middle Adulthood
Basic adulthood spans the ages of 25-40 (or even up to 65 in some opinions). The references from Sternberg are equally as applicable here as they were in the section on adolescence. IQ tends to be the big focus of those who study cognitive development during these years.
The most notable part of cognitive development during these years is not the new information that these people will acquire, but utilization of what they have learned. "People in their forties and fifties are better at solving problems that require the use of a store of practical knowledge" (Davis, 2004). The reason for this is that, "when middle adulthood is reached, considerable information concerning everyday problems and ways to solve them has been accumulated" (Davis, 2004).
It is often cited that as people age their IQ declines. Nettleback and Rabbit (1992) suggested that, "poorer performance on IQ tests may be the result of physical rather than cognitive changes" (Feldman, 2003). Why was the decline determined to be physical and not cognitive? It was suggested as such because of the slower reaction times present in people as they age. So, just because some is older and slower does not necessarily mean they have dropped in cognitive functioning.
Late Adulthood
From a cognitive point of view, at this stage of life, "fluid intelligence begins a gradual decline...whereas crystallized intelligence continues to increase gradually" (Davis, 2004). Why is this the case when people reach late adulthood? The evidence suggests, "as we grow older, we begin to experience difficulties in successfully encoding new material" (Davis, 2004). More recent studies show that there is a decline in memory as well as encoding. Mather and Carstensen (2005) suggests if there is a motivating cognitive factor present it will often have a positive effect on attention and memory. They begin the study by confirming how control over cognitive processes declines with age,
"Perhaps the most widely acknowledged psychological change with age is the decline in cognitive processes, especially memory. However, not all cognitive processes decline with age – not even all types of memory. One general characterization is that older adults have impaired cognitive control that is associated with deterioration in prefrontal brain regions. Thus, older adults show deficits on attention and memory tasks that require the generation and maintenance of internal strategies rather than just reliance on external cues. For example, explicit recall of words studied a few minutes previously was shown to decline across a four-year period whereas implicit memory of recently studied words did not show a decline with age" (Mather & Laura, 2005).
The up-side to this study was that older adults improve in the area of emotional control, "In contrast with the declines seen in cognitive control, age does not impair emotional control.
Compared with younger adults, older adults report that they focus more on self-control of
their emotions and rate their emotion regulation skills as better" (Mather & Laura, 2005).
The down-side to the whole discussion of aging and cognitive ability consists in the ailments that arise as people age. The most common issue older adults deal with is depression that is usually brought about by the, "death of spouses and friends...declining health...which may rob older people of their sense of control" (Feldman, 2003).
Other cognitive bearing issues that arise at this stage of life are dementia "the most common mental disorder of the elderly" (Feldman, 2003), and Alzheimer's disease, "a progressive brain disorder that produces loss of memory and confusion" (Feldman, 2003). It has been published that, "almost 50% of people over the age of 85 are affected by Alzheimer's disease" (Feldman, 2003).
Cognitive is fleeting thing as we age. No matter what type of spin the researchers might put on it cognitive development builds from birth to middle adulthood and then begins its decent. Does life really matter after age 85? If we pass 85yrs old will we be cognizant enough to know or even care? The moral of the cognitive process is for each person to maximize their abilities while they have the ability to do so.
At this point, the words of Solomon seem apropos,
1 Remember also your Creator in the days of your youth, before the evil days come and the years draw near when you will say, “I have no delight in them”; 2 before the sun and the light, the moon and the stars are darkened, and clouds return after the rain; 3 in the day that the watchmen of the house tremble, and mighty men stoop, the grinding ones stand idle because they are few, and those who look through [a]windows grow dim; 4 and the doors on the street are shut as the sound of the grinding mill is low, and one will arise at the sound of the bird, and all the daughters of song will [b]sing softly. 5 Furthermore, [c]men are afraid of a high place and of terrors on the road; the almond tree blossoms, the grasshopper drags himself along, and the caperberry is ineffective. For man goes to his eternal home while mourners go about in the street. 6 Remember Him before the silver cord is [d]broken and the golden bowl is crushed, the pitcher by the well is shattered and the wheel at the cistern is crushed; 7 then the dust will return to the earth as it was, and the [e] spirit will return to God who gave it. 8 “ Vanity of vanities,” says the Preacher, “all is vanity!” (Ecclesiastes 12:1-8, NASB).
Conclusion
Application of the information contained within this paper is and will be useful in any endeavor. For me this information is useful in my current situation as someone who teaches, shares, preaches, and sings about the Good News of Jesus Christ. How, you may ask? It is very simple to explain how it is useful. When it comes to helping others come to know Jesus Christ I have wisdom in the words of the man I consider to be the "last great theologian,"
" Every generation of Christians has this problem of learning how to speak meaningfully to its own age. It cannot be solved without an understanding of the changing existential situation which it faces. If we are to communicate the Christian faith effectively, therefore, we must know and understand the thought forms of our own generation. These will differ slightly from place to place, and more so from nation to nation. Nevertheless there are characteristics of an age such as ours which are the same wherever we happen to be" (Schaeffer, 1968).
Lack of sleep can inhibit information intake that in turn can leave gaps in learning. The gaps can be stumbling blocks in the cognitive development future of the person who allows games to keep them from sleeping enough.
The other issue, addiction, can be just as, if not more, devastating in terms of cognitive development. Like sleep deprivation, "Addiction of any kind limits life experience, with the harm especially severe when the brain is still growing" (Berger, 2011). Does the brain grow throughout adolescence? It does continue to grow, and a quick glance at the physiological aspects of brain development reinforce the warning of Berger, "The final stage is synaptogenesis, or the formation of synapses. Although the process (brain growth) begins before birth, it continues throughout life as neurons form new synapses and discard old ones" (Kalat, 2009). With limits on life experiences and improper brain functioning (due to the fact the prefrontal cortex is not fully developed until a person is in their early 20s), it would make cognitive development much more difficult at best or non-existent at worse.

For example, explicit recall of words studied a few minutes previously was shown to decline across a four-year period whereas implicit memory of recently studied words did not show a decline with age" (Mather & Laura, 2005).
The up-side to this study was that older adults improve in the area of emotional control, "In contrast with the declines seen in cognitive control, age does not impair emotional control.
Compared with younger adults, older adults report that they focus more on self-control of
their emotions and rate their emotion regulation skills as better" (Mather & Laura, 2005).
The down-side to the whole discussion of aging and cognitive ability consists in the ailments that arise as people age. The most common issue older adults deal with is depression that is usually brought about by the, "death of spouses and friends...declining health...which may rob older people of their sense of control" (Feldman, 2003).
Other cognitive bearing issues that arise at this stage of life are dementia "the most common mental disorder of the elderly" (Feldman, 2003), and Alzheimer's disease, "a progressive brain disorder that produces loss of memory and confusion" (Feldman, 2003). It has been published that, "almost 50% of people over the age of 85 are affected by Alzheimer's disease" (Feldman, 2003).
Cognitive is fleeting thing as we age. No matter what type of spin the researchers might put on it cognitive development builds from birth to middle adulthood and then begins its decent. Does life really matter after age 85? If we pass 85yrs old will we be cognizant enough to know or even care? The moral of the cognitive process is for each person to maximize their abilities while they have the ability to do so.
At this point, the words of Solomon seem apropos,
1 Remember also your Creator in the days of your youth, before the evil days come and the years draw near when you will say, “I have no delight in them”; 2 before the sun and the light, the moon and the stars are darkened, and clouds return after the rain; 3 in the day that the watchmen of the house tremble, and mighty men stoop, the grinding ones stand idle because they are few, and those who look through [a]windows grow dim; 4 and the doors on the street are shut as the sound of the grinding mill is low, and one will arise at the sound of the bird, and all the daughters of song will [b]sing softly. 5 Furthermore, [c]men are afraid of a high place and of terrors on the road; the almond tree blossoms, the grasshopper drags himself along, and the caperberry is ineffective. For man goes to his eternal home while mourners go about in the street. 6 Remember Him before the silver cord is [d]broken and the golden bowl is crushed, the pitcher by the well is shattered and the wheel at the cistern is crushed; 7 then the dust will return to the earth as it was, and the [e] spirit will return to God who gave it. 8 “ Vanity of vanities,” says the Preacher, “all is vanity!” (Ecclesiastes 12:1-8, NASB).
Conclusion
Application of the information contained within this paper is and will be useful in any endeavor. For me this information is useful in my current situation as someone who teaches, shares, preaches, and sings about the Good News of Jesus Christ. How, you may ask? It is very simple to explain how it is useful. When it comes to helping others come to know Jesus Christ I have wisdom in the words of the man I consider to be the "last great theologian,"
" Every generation of Christians has this problem of learning how to speak meaningfully to its own age. It cannot be solved without an understanding of the changing existential situation which it faces. If we are to communicate the Christian faith effectively, therefore, we must know and understand the thought forms of our own generation. These will differ slightly from place to place, and more so from nation to nation. Nevertheless there are characteristics of an age such as ours which are the same wherever we happen to be" (Schaeffer, 1968).
