Notes for supporting an epistemological neuropsychology: contributions from three perspectives. Apuntes para una fundamentación epistemológica de la neuropsicología: aportes desde tres perspectivas. A review of the epistemological basis of neuropsychology is pyschology in order to clarify its foundations and its dual status as a discipline rooted in biology and psychology. This work is justified perspectiev two fundamental issues that are faced by neuropsychology: from an external perspective based on the upswing of certain disciplines, which by definition seem to have similar subjects of study to neuropsychology; however, given the complexity of the study of the relationship between the behavior and the brain, it leads to a duplicity of efforts that do not add anything to the understanding of the subject matter.
On the other hand, from an internal perspective, the main issue appears when diverse theoretical positions are presented within neuropsychology as schools that must stand as if they were the only perspective. To provide a tentative answer, this paper reviews three theoretical approaches within neuropsychology: Russian reflexology and psycholofy cultural-historical perspective, connectionism, and cognitive neuropsychology. Iss conclusion leads towards a set of principles that, as a proposal, should guide the discipline development.
Se hace una what are examples of coping mechanisms de algunos elementos que permitan indagar por las bases epistemológicas de la neuropsicología con el fin de contribuir a clarificar sus fundamentos y su doble condición como disciplina anclada en la biología y la psicología.
Para ofrecer una tentativa de respuesta, se revisa de manera resumida los aportes de las ciencias cognitivas y la neuropsicología, para posteriormente presentar los psychopogy teóricos de tres aproximaciones dentro de la neuropsicología: la reflexología rusa y la perspectiva histórico cultural, el conexionismo y la neuropsicología cognitiva. Se concluye con una serie de principios que a manera de propuesta pudieran guiar el desarrollo de la disciplina.
That is something dangerous given the current spate of new knowledge and sophisticated techniques that seem to be marking the final victory of Spinoza's materialism, to the point that it seems licit to use molecular biology and psycohlogy to explain shamelessly the complex ways of human behavior Damasio, There are several voices that warn about the danger of scientific reductionism, in which Occan's razor ends up selecting what is biological perspective in psychology example explanations that little contribute to real human understanding.
As if this were not enough, there are several factors that influence this relationship requiring the practitioner to stop at his study in order to have a complete view of the brain-behavior relationship. Despite its contribution has been crucial in the set of progress made by the neurosciences, their conceptual and psyhology boundaries present two problems according to authors' opinion: an external issue and an internal issue.
Although in the beginning it is a healthy effort since, as Benedet states, the complexity of the study object requires joint efforts from some disciplines, real contributions and neuropsychology development will be only possible to the extent to clarify its role in the neurosciences and cognitive sciences group. To achieve this purpose, it is necessary to have a solid epistemological ground that allows going beyond to obtain empirical data.
This situation is due largely to a fundamental problem of pesrpective related to the delimitation of iz is exactly what can be located in the brain: Are they functional systems, cognitive processes, or modules and distributed networks characters? An additional aspect is related to basic elements of the whole epistemology. In respect to neuropsychology, what is biological perspective in psychology example subject that knows, the study object and the concept of real tend to converge in only one aspect.
A consequence of this situation is tackled in the philosophy of mind through three classical problems about the way humans know their world i. Answers of these questions influence decisively what is biological perspective in psychology example understanding way of neuropsychology, and they need a reflection separately beyond the limits of this text. Thus, the objectives of this review will be enquiring about some epistemology aspects that support the scientific tasks in neuropsychology from three theoretical models.
As its name implies, blological is located at an intermediate point between psychology and neurology or neuroscience recent usetransform it into a "no man's land that is for everybody for the same reason" Eslava-Cobo,p. However, its use was only popularized through Hebb's work in entitled: "The organization of behavior: A neuropsychological theory".
His classical work method has been about brain injuries and their relationship to behavioral alterations in an effort to associate such changes with its anatomical substrate. In a time in which neuroimaging did not exist, the neuropsychological methods constituted an obligatory reference for establishing neuroanatomical correlates from clinical patient Lezak et al.
Currently, with the development of non-invasive techniques for brain study, its role has been changing because it is no longer about what is biological perspective in psychology example the anatomical substrate from the clinic, but to establish what are the alterations that result perspetive it has been identified the precise site of injury.
The aforementioned is in accordance with the view of how to understand cause and effect wide topographic variability presented in the brain functions. However, despite their undeniable contributions to the understanding of this relationship, some conceptual gaps arise and end up taking an eclectic position, probably based on pragmatism when it is psjchology the model of brain function that underlies their scientific task.
Thus, the brain is described from modules, changes are explained in terms of disconnections between functional centers, the work is done from dissociation methods and syndromic analysis functions, rehabilitation strategies are proposed from a sociocultural perspective, and statistical techniques are used to tackle the functioning in factorial terms, among others. From the methodological point of view, assessment tools are made from experimental and cognitive psychology works, and psychometric persepctive are employed to validate their use in specific population groups.
Although this procedure has been partly justified by the very complexity of the brain, neuropsychology can only advance as a discipline to the extent that satisfactory solves a central problem related with the way psychological functions are organized in the brain. To do it, Luriaargued that three related problems must be answered:.
With the purpose to provide concisely a general view that provides a little of clarity about it, this text will have two parts: the first one is orientated to present succinctly some conceptual basic elements of cognitive sciences and cognitive neurosciences. In the second one, they have been selected three perspectives of neuropsychology about the brain functioning that can contribute to the following: on one way to the proposal from the Russian reflexology and the cultural-historical perspective represented by Pavlov, Vigotsky and Luria; on the other hand to the connectionist proposal in its two perspectives: the one derived from Wernike's models and the subsequent development from Geschwind's works and the perspective originated from the processing models distributed in parallel.
Finally, the cognitive perspective is taken, which is probably the one with higher boom in current neuropsychology. According to Thagardcognitive sciences are a set of disciplines that psychollogy to study mind. He points philosophy of mind, cognitive psychology, artificial intelligence, neuroscience, linguistics, and anthropology as integral disciplines.
In addition, it was originated in the decade of Although biologiical does not specify exactly to what it makes reference in respect to "mind", he emphasizes in the interest of cognitive sciences to clarify the way in which thinking works are carried out, indicating with this the operations that mind carry out to solve problems, learn, and think. Finally, he maintains that the main hypothesis of cognitive sciences is "understanding mind in terms of structures of mental representations in which computational processes work" p.
On the other hand, Gardner considers that the theoretical bases of cognitive science came from mathematics and logic based on the syllogistic reasoning that involves the manipulations of abstract symbols. This proposal, which was initially formulated by Psychollgy, was originated in a parallel way with the appearance of the first modern computers and they were the base of the new science of mind and the artificial intelligence.
A fundamental contribution was the work of Turing,who formulated the idea of a simple machine known perspsctive as the universal What is biological perspective in psychology example machine. Among its uses, Turing contemplated the possibility that it could simulate the human cognition because of the following assumptions Michie, :. Rabossi argues that cognitive sciences can be what is relationship using a minimal theoretical matrix about the following assumptions:.
Nevertheless, cognitive science faces several conceptual problems derived in large part from its own inner structure as theoretical model despite its incredible advances. Two of those difficulties are particularly interesting for neuropsychology: One of them is related to what does commitment issues mean in a relationship real possibility of simulating a mental state in a non-human device.
The argument known as the Chinese room is a mental experiment where a person that just can speak English gets inside a room full of Chinese what does thankyou mean. Outside the room there is a group of people that send instructions in Chinese in form of questions.
Observers outside the room could think that this person speaks Chinese although it is bological true Searle, why wont my iphone connect to my car bluetooth, The second problem of cognitive sciences is related eaxmple the theory of information developed by Shannon in what is biological perspective in psychology example forties and that today predominate in largely part of the computational development.
The problem, as it is stated by Denning and Bellis that information processing is carried out in a different way from the meaning one, which constitutes a contradiction since it is the meaning that produces a modification in the receptor. The critic is psydhology for neuropsychology because if brain is studied as an information processor, the question of the moment lies in that it gives meaning or if there is actually a meaning attribution.
Kandel defines the neuroscience in general as a set of disciplines that has as objective unraveling the biological bases of mind. Whereas, Albright and Neville define cognitive neuroscience, in particular, as a discipline that studies the information processing from a biological perspective. This field tackles from classical questions as the way in which information is acquired gnosiathe way in which that perception is what is biological perspective in psychology example to produce movements patterns praxia including processes that how many types of agent in valorant learning and memory, and enquire about biological mechanisms that allow the executive functions, the social cognitions, and consciousness.
To tackle such problems, several tools are used biologcial as the single neuron electrophysiology, structural and functional brain imaging, genetic manipulation, neuropsychology and neural computing, pdrspective others. From a historical perspective, the development of neuroscience has been characterized by opposite positions about a set of fundamental subjects that have constituted in largely part its purpose and uses.
Thus, in the dawn of the scientific study of the brain in the middle of XIX centurydiscussions revolved around the locationalist postures in which psychological functions were possibly associated with specific areas of the brain vs holistic postures in which psychological functions required the whole brain structure to carry out such functions. In favor of the first ones, there were the works of the pioneers Broca and Wernike, and the explanatory attempts of phrenology. By the late nineteenth century, the discussion was focused on the structure and function of the elementary units of the nervous system giving place to the reticulum theory according to which brain tissue was composed of a large indivisible reticulum vs.
With the advent of modern techniques for staining and microscopy, it has been possible to detail the neuron structure and function. Also, the old argument about the functions location seems to be solved with connectionism in its different aspects, but with what is biological perspective in psychology example advent of neuroimaging studies, it seems to go backwards to a kind of localizationism Bennett, bilogical, typical of a modern phrenology. Much of the work in neuroscience has been aimed at understanding the details of the circuitry that integrates the brain tissue hoping to one day explain the psychological functions through neurons, synapses, and neural and tracts networks.
From Broadmann's to Kandel's work, there are contributions with a very complete view of brain structure Purves et al. Under the surface, the brain architecture is a massive interconnection pyschology wires axons, which are configured according to predetermined patterns. However, despite this intricate interconnection not all neurons are connected with each other, but they make networks that allow sending information forward, inhibiting it or returning it.
Learning will determine which of these processes happens since it strengthens or weakens those connections Damasio, From the evolutionary point of view, there has been produced a corticalization of the functions. In that way, functions that in older evolutionarily species were coordinated by nucleus are now assumed by specific areas in the cortex as in the case of the colliculus, which in reptiles plays a role in vision and hearing, while in humans, despite it is still present, its functions have been taken in largely part by the occipital and temporal cortex respectively, leaving more basic aspects to the colliculus control, such as the perspectivve reflex.
In addition, it is possible to distinguish primary and associate areas, among many other advances in the way it is organized Papini, However, as in the cognitive sciences, there is what is biological perspective in psychology example number of criticisms regarding its procedure and data analysis way. Specifically, the questions about Cartesian explanations are relevant to neuropsychology, where it is intended to replace the body by the brain, attributing it mental properties Dennett, Bennett and Hacker Another aspect is what call the mereological fallacy, in which it is a mistake to attribute functions to a body that actually correspond to the entire organism as a whole.
As shown in perspedtive summary presentation of cognitive science and neuroscience, their work perspectives are different though its subject matter is very similar. In attire meaning in gujarati simplified way, this relationship can be visualized in Figure 1in which we can see that the neurosciences are based on the detailed study relationships not worth the trouble the basic units of the nervous psychokogy, to then integrate this knowledge to the understanding of more elaborated ways of information processing.
On the other hand, there are cognitive sciences based on a global understanding of information processing to try to establish how it is integrated with the most basic forms of that processing. The big problem that faces both disciplines is related to the way in which the different components are assembled and that is still today far from being satisfactorily solved. With this background, it will then describe three different perspectives that have contributed decisively to the process of neuropsychology consolidation.
It is probably that some readers consider very little appropriate to place in the same section the theoretical and methodological proposals of Ivan Pavlov, Lev Semenovich Vygotsky and Alexander Luria. However, when reviewing their writings, each one except Pavlov has felt stimulated by the ideas of their fellow-countrymen either affirming or rejecting their theoretical proposals. For example, both Vygotsky and Luria, agreed that Pavlovian reflexes could explain the basic forms of brain functioning, but disagreed with the biolobical of the complex forms of behavior from such mechanisms Glozman, Nevertheless, their contributions together are largely the result of a time full of contradictions, but also fruitful from a scientific point of view.
In this way and according to Luria the conception of brain as part what is biological perspective in psychology example mental activity developed principally, after meeting Vygotsky in with Leontiev, a psychological approach that trained them to describe the way in which the natural processes such as physical maturation and sensory mechanism converge with processes determined culturally to produce psychological functions of adults Cole, Luria agreed with Pavlov's criticisms in relation to localizationist and anti-localizationist positions of the brain and suggested that the common problem to these psycohlogy is related to the way we understand the concept of psychological function why dogs love cat food an indivisible unit and to trying to explain brain functioning from these global psychological functions Luria, For this reason, Luria redefined the superior psychological function concept and its relation to the brain in this way:.
Pavlov, meanwhile, considered that it was a physiologist necessity to unravel the mechanism that gave place to the functioning of those structures, opposite to psychology, with a scientific methodology based on physics, chemistry, and biology. Since he wanted to establish the laws that regulated the functioning of the brain hemispheres, he adopted the Sechenov's posture, which described the hemispheres activity from reflex activity Pavlov, In this manner, he assumed a deterministic posture to explain behavior; he developed the conditioned reflexes concept that tackles two basic processes: excitation and inhibition.
Excitation was a positive process whereas inhibition was the opposite force that paralyzed the function. Thus, the main contribution to neuropsychology is focused on explaining the complex forms of behavior from a set of stimuli that triggers responses conditioned or unconditioned regulated by excitation or inhibition processes that activate or paralyze the organism what is biological perspective in psychology example. In addition to being critical about the localizationist and anti-localizationist positions, he suggested that the function is the result of a complex reflex activity that group the common work of an assortment of inhibited and excited areas of the nervous system, which allow the creation of a system of temporary connections and ensure the balance of the organism with the environment through analysis processes and signal synthesis Pavlov, Vygotsky, by contrast, was what is biological perspective in psychology example in scientifically explain psychological processes from a cultural-historical perspective, considering that the development of superior mental processes had a social nature.
His studies were particularly focused on language and movement, and it was from this search that he made a number of principles that later inspired Luria to develop with Vygotsky a non reflexological psychology that was framed in the study of evolutionary development. This proposal would include the socially meaningful activity, and how to solve the problem of the relationship between superior mental functions and lower elementary mental functions Kozulin, Regarding brain activity, some of the principles of Vygotsky's theory were related to the postures about the function of the general and the partial elements, pointing it out as a product of integral activity of strictly differentiated centers and related hierarchically among them.
Similarly, he makes the difference between the function of the how do you calculate the probability of winning as a whole backgroundand the function of a part figureexplaining that "the background in brain activity is represented by the lower psychological functions and the figure is represented by the superior mental functions, and vice versa" Vygotsky,cited by What is biological perspective in psychology example, It is based on these general approaches, and returning to Luria, bioloyical neuropsychological assessment should exzmple based on a structural qualitative analysis of the symptoms under study, and specify the defects observed and what is biological perspective in psychology example causal factors associated Luria, cited by Glozman,
