neuroscience perspective strengths and weaknesses

Neuroscience as a field is hindered by underpowered study designs that involve sample sizes that are too small. Socioeconomic status and the developing brain. (2012). As discussed, small studies in individual laboratories can be useful for demonstrating proof of principle (brain defects in area X appear to cause impairment Y), but such studies cannot assess the strength of the causal relationship (akin to the genetic concept of penetrance). Developmental Cognitive Neuroscience in the Era of Networks and Big Development as a dynamic system. Neuroscience must also embark on large normative studies to understand the prevalence rates of brain defects and functional impairments in the general population. To find behavioral evidence that could corroborate or disconfirm the presence of cognitive impairment, the expert examined personal writings, journals, datebooks, calendars, checkbook records, and financial records for a three year period surrounding the time of the offense and concluded this analysis showed no evidence of impairment or change in his management of his everyday affairs (Ref. Cognitive perspective Theorist Ulric Neisser Lev Vygotsky Jean Piaget Main Idea The cognitive perspective is based on the assumption that the brain is the most essential factor in how an individual behaves or thinks. doi: 10.1016/j.neuroimage.2009.07.003, Rueda, M. R., Checa, P., and Cmbita, L. M. (2012). Not only do researchers fail to detect real effects, but of more concern, they may also falsely determine null effects to be real. Copyright 2015 Lipina and Segretin. Child Dev. Because of these known limitations, the American Academy of Neurology and the American Clinical Neurophysiology Society have adopted a position that recommends against the use of qEEG in civil and criminal judicial proceedings,10 although it should be noted that there are proponents of qEEG that dissent from this position.11. Psychol. The scientific nature of the approach is one worthy of discussing as it can be both a strength and weakness, as is its reductionist nature. Additionally, it should be important to use conceptual models aimed at understanding the transfer of gains across different domains beyond laboratory methodologies, such as school and work achievement (Crone and Ridderinkhof, 2011; DAngiulli et al., 2012; Goldin et al., 2014). 75, 610615. Cumulative risk and child development. Psychoanalysis refers to both a theory and a type of therapy based on the belief that all people possess unconscious thoughts, feelings, desires, and memories. Rev. Cognitive psychology--the study of how people think and process information--helps . doi: 10.1037/a0031808, Ganzel, B., Morris, P., and Wethington, E. (2010). J. Clin. 16, 708712. For such a purpose, it is necessary to encourage the design of interventions and the measurement of outcomes driven by theoretical models to include the consideration of underlying mechanisms at different levels of analysis. doi: 10.1111/desc.12081, Neville, H. J., Stevens, C., Pakulak, E., Bell, T. A., Fanning, J., Klein, S., et al. A dominant cognitive approach evolved, advocating that sensory information is manipulated internally prior to responses made - influenced by, for . Sci. Mr. Weinstein's lawyers signaled their intent to use the neuroimages at trial to establish that he was insane. J. Neurosci. Specifically, exposure of different species to enriched conditions, in comparison with either standard or deprived environments, has been associated with several structural changes in neurons and synapses, glial components, brain vasculature, brain cortex weight and thickness, rate of hippocampal cell neurogenesis, availability and metabolism of both neurotrophi factors and neurotransmitters in different brain areas, and neurotrophic and neurotransmitter gene expression (Hirase and Shinohara, 2014). Hum. Neurosci. (2010). You may wonder why there are so many different psychological approaches and whether one approach is correct and another wrong. Each technique has its strengths and weaknesses, and knowing them allows researchers to decide what each offers for . Lipina, S. J., and Posner, M. I. Environmental acoustic enrichment promotes recovery from developmentally degraded auditory cortical processing. 46, 156162. Similarly to many areas of study on the effects of poverty on development, epigenetic analyses of early brain development in humans are in their early stages. Neuropsychological testing, unlike neuroimaging for the purposes of cognitive assessment, is generally extensively validated and normed. Sensitivity and specificity can be estimated with small studies, but ascertaining predictive values requires knowledge of prevalence rates of the defect and impairment in the relevant population.41 For the nonspecialist, the basic concept to grasp is that without large surveys of brain structure and function in the general population, we cannot know how many people are walking around with brain imaging anomalies but are functioning normally, because such individuals rarely come to the attention of research studies. One of the main disadvantages of the cognitive psychology is that it refers to a process that we cannot directly observe, as it relies heavily on inference. We are well-suited to analyze behaviors, having evolved both neural hardware (expanded areas of the brain that support theory of mind)44 and software (folk psychology)45 to ascribe intentions to the behaviors of others as a matter of survival.46 However, the same areas of brain that allow mentalization also enable deception47 because we can best deceive when we know how other minds work; behaviors can be faked, so malingering is a perennial concern. Despite the effort it takes and the fraught nature of decision-making in which freedom, life, and treasure hang in the balance, that is the way it should be. Acad. Neurosci. This also implies: (a) the support of methodological innovations in the analysis of neural connectivity for studies that compare different intervention contexts (e.g., home, school, community), its mediators, and the potential requirements for the intervention designs (e.g, Jolles and Crone, 2012; Lipina and Posner, 2012); and (b) the generation of alternative methodologies aimed at overcoming limits in sample size, timing of longitudinal designs, and levels of analysis (Gianaros and Hackman, 2013). To answer the question of how likely is brain defect X to cause impairment Y, we must have a sense of how many people with the brain defect have impairment and how many do not (if many people have the brain defect but not the impairment, the causal relationship is weak). Vulnerable Child. The nervous system not only works to produce thoughts, emotions, and behavior, but also controls important body functions, like breathing. Frontiers | Strengths and weakness of neuroscientific investigations of For confirmation, we must look to other kinds of evidence. No use, distribution or reproduction is permitted which does not comply with these terms. doi: 10.1038/nrn2639, Michel, G. F., and Tayler, A. N. (2005). Family-based training program improves brain function, cognition and behavior in lower socioeconomic status preschoolers. Psychological Perspectives And Strengths And Weaknesses doi: 10.1016/j.tics.2008.11.003, Hackman, D. A., Farah, M. J., and Meany, M. J. Some of the strengths of this theory include the focus on both the positive nature of humankind and the free will associated with change. weaknesses attention emotion learning / memory motivation perception too oriented towards micro-level considerations can lack specificity: nature vs nurture refers to practically every aspect/variable affecting human responses. (2013b). In all of these studies, there has been an emphasis on the behavioral levels of analysis (e.g., Goldin et al., 2014; Segretin et al., 2014), and both neuroimaging techniques and molecular and behavioral genetics have been included in some cases (Rueda et al., 2005, 2012; Bryck and Fisher, 2012; Espinet et al., 2013; Neville et al., 2013b). 138, 109133. In addition, based on overactivity and the amygdala's known role as the brain's fear center, the defendant likely had overwhelming levels of fear at the time of an alleged offense, thus arguing for diminished culpability. In this study, these theories will be . Educational Researcher, November 1989, 18 . Front. Hearing ability depends on different degrees of environmental noise exposure (Zhou and Merzenich, 2012), and acoustic enrichment of the environment may promote recovery of auditory cortical processing (Zhu et al., 2014). Sci. A bar chart can be generated by a grade schooler on her smartphone, but a functional magnetic resonance image (fMRI), for example, carries with it the imprimatur of big science, as it requires expensive machines and legions of geeks to generate. (2012). I have found that although neuroevidence is rarely dispositive on its own, it can be very useful to direct and support other kinds of evidence, such as neuropsychological testing and old-school behavioral analysis. It can help researchers find ways to prevent or treat problems that . doi: 10.1111/j.1467-8624.2011.01641.x, Evans, G. W., Li, D., and Whipple, S. S. (2013). However, the most pernicious error here, one that is not easy to spot, is the claim that because the amygdala is the fear center, activity there indicates that the defendant was experiencing high levels of fear. 27, 549579. These three types of evidence work well together because they can compensate for each other's relative weaknesses, while combining their strengths. Knowing how things typically work can help shed light on what may happen when there are problems. Perspect. If ADHD is seen as a problem of inhibition, planning and control, then it is logical that tests of general intelligence, which were not designed to measure these cognitive processes (Wasserman . Cognitive Approach in Psychology Explicit and implicit issues in the developmental cognitive neuroscience of social inequality. [13] Sources: Gardner, H., and Hatch, T. Multiple Intelligences Go to School: Educational Implications of the Theory of Multiple Intelligences. Prog. Trends Cogn. Moreover, the consideration of sensitive periods for many processes susceptible to different socioeconomic conditions and timing of intervention requires a revision of the agendas in other disciplines addressing childhood poverty (e.g., many disciplines currently contend that the impacts of economic and social deprivation are permanent and irreversible) (DAngiulli et al., 2012). Strengths and neuroscience: developing a strengths focused habit Certain patterns have emerged: speculations clothed as facts, errors of logical reasoning, and hasty conclusions unsupported by evidence and unrestrained by caution. doi: 10.1111/j.1467-7687.2012.01147.x, Raizada, R. D. S., and Kishiyama, M. M. (2010). Neighborhood disadvantage and adolescent stress reactivity. The study of how adverse environmental conditions (e.g., socioeconomic status (SES) or poverty) influence brain organization and reorganization during development includes different approaches. I discuss two fundamental problems that limit the evidentiary utility of neuroscience-based claims: the problems of reverse inference and group-to-individual inference. In terms of impacts, mediating mechanisms, hypotheses and the interpretation of data obtained by applying molecular, behavioral, and neuroimaging techniques seems to focus mainly on the comparison of performance and degree of activation rather than the identification of mediating mechanisms (Hackman and Farah, 2009; Lipina and Colombo, 2009; Hackman et al., 2010; Raizada and Kishiyama, 2010; Lipina and Posner, 2012). 6:277. doi: 10.3389/fnhum.2012.00277, Hackman, D. A., and Farah, M. J. To answer the inverse question of whether impairment Y is likely to be caused by brain defect X, we must know how many people with impairment have the brain defect, and how many do not (if many people have the impairment but not the brain defect, then another cause is the more likely explanation). Youth Stud. However, as discussed above, neuroscience-based claims are limited by problems of reverse inference and group-to-individual inference and thus can rarely go beyond establishing that an impairment is plausible. Neuroscience as a field is hindered by underpowered study designs that involve sample sizes that are too small. Developmental cognitive neuroscience is being pulled in new directions by network science and big data. Since the mid-1990s, researchers have applied neurocognitive behavioral paradigms to compare the performance of children with disparate SES, and technological advances in neuroimaging have allowed for the analysis of neural networks (Hackman and Farah, 2009; Lipina and Colombo, 2009; Hackman et al., 2010; Raizada and Kishiyama, 2010; DAngiulli et al., 2012; Lipina and Posner, 2012; Gianaros and Hackman, 2013). Behaviourism: "Behaviourism (also called behavioural psychology) refers to a psychological approach which emphasises scientific and objective methods of investigation" (Simple Psychology, 2016). us. Neural correlates of socioeconomic status in the developing human brain. Neuroevidence such as brain scans have several strengths. doi: 10.1080/17450128.2010.521598, Lupien, S. J., McEwen, B. S., Gunnar, M. R., and Heim, C. (2009). Six Major Psychological Theories: Strengths and Weaknesses Term Paper Chapter 10.4: Research on Humanistic Theory - AllPsych In all these approaches, the focus of the analytical efforts was on the analysis of the mechanisms mediating stress responses, which took into consideration a number of guiding principles that could contribute to the understanding of childhood poverty. 51, pp 191192). When positive psychologists advocate a strengths-based approach, I hear it as an important . Commun. Psychobiol. This analysis is time-consuming and requires methodological innovations for the exploration of molecular pathways, systems and behavioral events, and phenomena simultaneously, and throughout the different stages of development (e.g., Rao et al., 2010). (2013). Evidence of the modulation of epigenetic mechanisms during early development in individuals growing under different rearing conditions (e.g., deprived SES, stress exposure) has recently been incorporated into this line of research. A gradient of childhood self-control predicts health, wealth and public safety. qEEG signals have not yet been adequately characterized in the general population, and definitions are needed to distinguish what is a normal or abnormal signal in the first place. Neuroscience Debate - Advantages and disadvantages table in A Level and the Neuroscience Perspective by bob joe - Prezi It is generally accepted now that brain functions are indeed localized (functional specialization18), but only to a certain extent. Alfred Adler's Theories of Individual Psychology and Adlerian Therapy Psychobiol. doi: 10.1111/desc.12087, Shonkoff, J. P., and Bales, S. N. (2011). In other words, although we may be guided by science in making moral decisions, ultimately they remain ours to make. doi: 10.1038/nrn2897, Hensch, T. K. (2004). (2012). However, that theory has not yet been proved by brain research. Search. Furthermore, we must understand the kinds of questions neuroscience will never be able to answer. Understanding the Strengths and Weaknesses of Intelligence and Environmental noise exposure degrades normal listening processes. Studying the nervous system advances understanding of our basic biology and body function.
