The search for talent: the Holy Grail

There is a  common idea,  noticeable from psychologists and educational experts, about put  labels to learners and give them a place in an imaginary continuous line that cluster outstanding skills in the right side and educational needs at the left side.

If it's looked the continuum, everybody at the left or right requires special education or supports, and at this case, it must be admitted that not everyone learns the same way. But a second glance, suggests that all who are in the middle of the curve, have no problem.

Certainly there is no more pride for  parents that their child can be declared as gifted, while there is no greater grief than when someone tells them that their child will not be able to learn more than  few skills. The rest of the parents clean the sweat when their stems are declared as normal, not having this any other implication beyond what a psychologist says.

Going deep into this subject, there is much more that experts do not report.

The forward of the book La educación de niños con talento en Iberoamerica (Education of gifted children at Ibero-America) opens saying, "All people are entitled to receive an education that develops their full potential and allow them to build a life plan" (Benavides, Maz, Castro and White, 2004).

With  this idea, then it is clear that those who are at  the left side of the  curve would have the opportunity to develop skills while those who have the right side can not move beyond, since they know more than anybody else, they have reached the maximum their abilities based on scales of talent.

The text describes programs, ideas and notes about  how to work with  talented children in several countries, but if these children are the greatest intellectual achievement, is it possible to teach even more?.

The talent from psychology

In the purest psychometric eagerness has been measured the intelligence and the possible capabilities, searching to find those common features on the continuum of the curve of intelligence. For those who are at the left, it was assumed that lack the intellectual, emotional or social skills to relate with those who are at the center of the continuum (Winner, 1998; Artigas Pallares, 2003, Martos and Help 2004). While those who are at the right have a high intellectual capacities measured with psychometric instruments (Pendarvis, Howley & Howley, 1990; Lohman, 2000; Lohman, Korb and Lakin, 2008). But they lack the emotional skills to adapt to those who have left or center of the continuum (Genovard and Castello, 1990; Freeman, 2005; Freeman, 2008; Freeman, 2010).

But not everything that intelligence tests measure is useful to adapting to the environment: for example there are important aspects of the real-world intelligence that are not considerate. On the other hand there is a debate if that perspective is confusing intelligence with rationality, issues that do not necessarily go hand by hand (Stanovich, 2009). That's why even the smartest people can do things that are considered irrationals. At the same time, psychometric tests forget an important feature of the brain: emotions (Freeman, 2008). This aspect has been widely documented as the primary difficulty in children considered talented.

Stanovich (2009) shows that there are features such as divergent thinking or aspects of the  everyday life that have nothing to do with what psychological tests measure, moreover, when students have the opportunity  to reply  to problems, it may surprise to expertise researchers, for example, when gifted children can talk to  others about science and feel good by providing creative answers, beyond which we have assumed is the only one correct answer ( Freeman, 2003), or when a child, considered with limited capacity, achieved a task for which he or she has worked for several hours. And  those that are supposed are  the differences, actually are the result of the brain architecture, which is molded with repetition and experimenting with  the environment  (Manaut-Gil-Casares Vaquero, Quintero-Gallego, Pérez-Santamaría, Gomez-Gonzalez, 2004).

Thus, from the speech of educational experts that sounds so melodious, the obvious question is: IF "All persons are entitled to receive an education that develops their full potential and allow them to build their project of life", Why is segmented the continuum?, Why can we have only one position?, Why can't be together?, maybe to create an elite education?.

From the standpoint of Renzulli (1978) the differences between the continuum are not only concentrated in one area as many authors propose (Parra, Ferrando, Prieto and Sanchez, 2005; Rogers, 2006; Valadez Sierra, Betancourt Berbena Morejon and Zavala, 2006) they are determined from different skills set out in three areas: high intelligence, creativity and involvement in the task.

Can a child with Down syndrome or Asperger be creative?, If your reply at the speed of light that does not, then please do not continue reading this article,  you are not creative. Creativity involves providing innovative responses to common problems. And it's not a mystery that daily work requires creativity and divergent thinking abilities, however, this is not developed at educational institutions at basic or higher level (Solomon, 2007).

Considering its capacity, each new brain must be trained to grow from environmental stimulation; a process that needs decades and each person must discover for itself all skills needed to be employed on that journey called Life (Tubino, 2004). And it doesn't depend of any curricula or educative legislation.

Accepting that the human brain still evolving (Fox, 2011), depends on synaptic communication, the development of structures and protein exchanges neurotransmitters (Haier, 2009), makes learning a more complex issue than just locate someone on one side or the other of an imaginary line, and open a door to understand that learning is not something that can be X-rayed by a test applied at a specific time.

Neuroscience research suggests that human abilities depend on the neural network architecture, which is related to the space where the brain develops, as it is confined to the skull, shaping each structure in a particular way, some areas can be over-exposed to stimuli preventing the development of other areas, under two assumptions: the law of survival of the fittest and its use related with environmental responses (Roberts, Anderson, Husain, 2010). So that it’s not possible to talk about standardized education and less, support the idea that everyone learns the same way.

And it must be added the fact that there are other actors in education, research showing that success in the case of gifted children, has a big support of maternal scaffolding, that makes the difference between passing from a skill to another (Morrisey, 2011) and the same from mother of children with developmental disorders, since they are who promote socialization skills in their kids, if there is any doubt, it's only needed one question:  who did teach you how keep attention while reading?.

Talent does not equal intelligence

The talent or giftedness refers to that ability or skill set which has a particular facility (Prado Suarez, 2006), but the definition of any author, never says that it is restricted to the fine arts or science or sports. If so, where do entrepreneurial talent, or create or play video games fall?.

Intelligence is adaptation to the environment (Genovard and Castello, 1990; VanTassel-Baska, Xuemei Feng, Brown, Bracken, Stambaugh, French, McGowan, Worley, Quek and Bai, 2008), an action that requires talent. Though not necessarily arrive together, this worth mentioning, for example that as highlighted in the Savant, which is a developmental disorder that is part of the autistic spectrum. Main feature of this syndrome is that people can have a widely talent developed at the same time a profound intellectual difficulty (Winner, 1998).

Thus, it is argued that the provision of skills of each person, although it has a genetic aspect, at the same time depends on environmental stimulation (Willard-Holt, 2008).  Every one can have a special talent for playing the piano in an extraordinary way, but if you never had a piano in front, the talent can not be developed. That's why experience shapes capacities that will be most useful. However, genetic damage as those presented in the development disorders also shape brain structure.

Brain studies reveal that the patterns of gray and white matter and metabolic efficiency may delineate individual differences related to intelligence. That's why the smartest brains work differently (not better) in the strongest areas that has a better domain (Haier, 2009).

What structures will be more developed?, those that are  used more frequently, and that is because of the skills that create, cause more satisfaction in completing tasks. That feeling of: I can do it (Prado Suarez, 2006). However, under the law of the strongest, the strengthened  structures, will push and eventually block the development of the  other less useful  (Haier, 2009) which is why you can not be expert in everything, because the skills will be permeated by the use and management of them.

In the case of arithmetic, it’s found that the frontal lobe is more involved in this activity, and also opens the path to memory processes and analytical thinking (Serra-Grabulosa, Pérez-Pàmies, Lachica, Membrives, 2010), Even though, a good mathematician not necessarily is a good writer of poetry or have social skills. Einstein maybe is a good example.

Conclusion

In conclusion, it can be said that the differences in the continuum that psychologists have called intelligence, is simply due to the cytoarchitecture of the brain and that it results from interactions, and this determines the capabilities that each possesses. Starting from the extreme neuronal flexibility that, that which is not known today, can be learned from the appropriate teaching strategy, which may be different for each depending on experience.

Under the motto: “Everyone is entitled to receive an education that develops their full potential and allow them to build their project to life", there shouldn’t be distinction what side of that continuum is, left, right or in the middle, all people have the ability to build a life project, based on their own abilities and who is not able to tie your shoes, you may have the ability to paint pretty colorless pictures.

Academic skills are not the only ones that are valid in life; there are also artistic and sporting activities. There are sports stars, who have not reached higher education, but they have adapted to environmental needs and above all, they are happy.

Under this idea, the separation of the continuum although it may have educational benefits, it makes no sense neuro cognitively, and that all people have the right to find a place in life, a happy childhood and successful adulthood.

Memory and language

Alma Dzib Goodin

When we talk about memory, in general is associated with the past and memories, however, memory has a lot to do with language, because while we structure a phrase, many temporal associations are carried out either at present, past or future. I don't think is necessary explaining too much this aspect, since everybody suffers with   verbal conjugation at the first years of formal education.

And this is because the brain is constantly influenced by spatial and temporal patterns across of all the senses (Hawkins and Blakeslee, 2004), and then we say, of course, I had read that!, or it tastes like ... and ate it at....

During a conversation, is important to pay attention if you are talking in present tense, past or future, since this depends on the structure and meaning of the sentence. Of course, this is not knowledge that a newborn uses from day 1, it's one of the many tasks to be learned over time, related with brain maturation, environmental demands and verbal skills, some of them imposed by genetics.

Then, how can a brain work with multitasks?. It does this primarily by electrical impulses that travel through the synaptic connections, that are fired every 5 milliseconds, which work  parallelizing tasks, I mean, it does many things at once and at different levels, it performs tasks consciously and others unconsciously and also pay attention to the environment and the details (Hawkins and Blakeslee, 2004; Glöckner and Witteman, 2009).

But if focus at the language, the maximum achievement of the neocortex is the grouping of ideas, which can occur in prospective, this is, think ahead. During a conversation, we can predict what the speaker will say or do, this is an important process not only for language, but when we are driving a car, or watching a movie, which is an aspect of memory (Brewer and Marsh, 2010).

And of course, it's not possible ignore the great speed with which it is possible to remember something when the stimulation and the conditions are right. This is called reaction time in laboratory experiments, but that is pure fun when we play table games that require a unique quick response, which of course is a process that requires an active memory and familiarity of stimuli (Brewer and Gimbel, 2011).

But I guess, you reader   know your strengths in aspects of memory. Despite what teachers say that we must remember everything they say, our brain has something else in mind (that is literally). And while some people have better visual memory, and can remember what they saw or read just once and remember the name of the author of the book or article they read, there are some others who remember much better if the stimuli are auditory, and they learn to read loud to retrieve information better. There are also those who remember motor tasks and they are able to remember things when they do a movement. And I can not forget to mention my deep admiration for those who can recognize flavors, or the aroma of fine wine or a good meal.

Tasks that seem simple become complex when we try to explain them, for example, the recognition of faces is a complex but essential aspect in life. This process begins in the first days of life; it depends on the maturity of the oculomotor muscles and provides assurance that the caregiver is always the same. But it’s not the only one, because the sense of smell provides protection while babies develop the ability to focus objects. Thus, little by little they are making a complex network of processes that, with no doubt, help  to let us to know that we talk to someone we  know.

So, How do you remember a face?, Is it remembered or recognized?, this will be  another topic, that I will take as a  excuse to write again, but the fact is that  process is complicated: it starts with the rapid identification of the face, if it has similar racial characteristics, this can be a first  kind of identification, if not, you will have to considerate many details: the color of eyes, its location, shape, distance between them, the characteristics of each one and then the shape of the face, color, contour, form hair, color of the eyebrows, lips, cheekbones (Ewing, Pellicano and Rhodes, 2010), thus intersect other details such as whether the person is attractive, if we recognize that person and then, maybe we will try to find a  name in the library of memory, making a comparison  between face, name and a location where that person have seen  before.... and all that will be done in millisecond,

Of course, sometimes the process is not accurate, and the identification finishes with no an idea who is speaking with us. And even in that case, you can try some  clues as: if the other person knows or not my name?, the topic of conversation?, If I talk about this then I know this place, other clues can be the tone of voice, familiarity ... the system continues the search until it can  finds a positive recognition ... but you don't have to feel shamed if all the process fails, it may be easier to recognize the voice, or other aspects, such as recognizing the other person car, bag, shoes? ... each person is inclined to recognize objects in the environment in a distinctive manner.

In general, though not exclusively, men are capable of distinguishing details between cars, a Porsche and a Lamborghini are not equal, a Prius and Acura are not similar at all, and Who can confuse a beetle and an MDX?. Personally, I only know that cars have wheels and need gasoline, sometimes.

But vision is not always the main form of recognition. I used to feel worry  the first few times I waited for him at the airport, for who is now my husband, I was not able to make a mental image of his face. I only remember he had blue eyes and red hair. So I just could wait for someone with these features, but it was a challenge. The only consolation was that maybe he could recognize me, and when that happened, his voice did not let me any doubt, he was the right person.

Of course, once the recognition is done, the face has a name ... the vision is related to language when is trying to tie a memory. When everything matches, it's not necessary more searching at the data banks, all features are tied, but the issue is more complex than it seems, because although all that is accomplished in a few seconds, the search for the information needs of different brain areas and all information is concentrated in the hippocampus (Ewing, Pellicano and Rhodes, 2010).

If a task as simple and everyday as face recognition takes so much work, just enough to imagine the process of recognition of words, tense, voice tones, volume, modulation and content during a conversation.

Starting from the idea that thought is private and language is public, and then speak is making public the private. (In so many years, I can not remember from whom I learned this in my first years at university). However, both processes are completely different. But this  is conceivable under the multi-tasking system, because while we feel good or bad with  the external temperature, we plan activities for the next few hours or the next day, make a to do list, we feel hunger, we make mental notes of what to say on the next business meeting, we try to remember if we fed the cat and locked  the closet door or if we turn off the light ... the tasks can be endless, but, language only accepts the execution of a letter at a time, to form a word that is part of a sentence, to form an idea, and is able to link with the following (Weimer and Palermo, 1974).

We remember  what it was said, what is being said and what we are going to say,  or we can predict the next sentence, in studies  of laboratory, researchers try to see  separate processes, but in everyday life, they  are seemingly inseparable.

And all this has been learned in daily interaction, even before a first word can be said, and when babies start practicing, of course they make verbal mistakes, because their memory is not consolidated yet. But nobody cares about these failed attempts; adults encourage toddler to try it again, and again.

Different brain areas are used depending the kind of speech, for example, if we are talking about colors, there is an isolated portion of the brain that needs to be involved, but if we are trying to do a voice recognition, or shapes, other areas must work together, because all processes are separated, and then re grouped into the brain, but yet it's not possible to understand how this is possible.


That's why learning in children, can not be based only in isolated memorization and meaningless, specially because there is a specific area where all information must be joined and summarized to give sense to the world. But on the other hand, remembering can be   too inconvenienced because when an area of the brain is over specialized, it means another area is compressed, and this can be the case of talented or gifted children for whom the neocortex is the raw material in exchange for neglecting the social skills (Herbert, 2005).

The clearest case of this are  people with a diagnosis of Savant Syndrome, whom are able to remember very little details of what captures their attention, but sometimes with an IQ less than 50 (Winner, 1998).

Remembering then, depends on the attention, of environmental stimulation and the hippocampal ability to recognize tasks (Brewer and Gimbel, 2011). Does it seem complex?, Well, if you  try to explain it using only electrical impulses, bio chemicals, neural connections and a little knowledge of neurophysiology, if it is, but it's an activity that every brain does every  day, every second each day of our lives ...
