The cognitive approach is highly influential in all areas of psychology (e.g., biological, social, neuroscience, developmental, etc.). Because all known brain areas are involved in multiple processes, knowledge of activity of a single area cannot by itself establish what that brain area was doing at the time. Neuroscience; See All. (2002). 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). Unlike neuropsychological testing, neuroimages are intuitive and concrete (everyone understands that a hole in your head may cause thinking or behavior problems) and naturally command attention because of their novelty, beauty, and associations with scientific authority. I remain hopeful, as does Bruer, that the indirect evidence from neuroimaging and other neuroscience research has the potential to suggest teaching strategies and environmental stimuli that are valuable for learning. Many different techniques are classified as psychophysiological. 10, 434445. Psychobiol. Educational Researcher, November 1989, 18 . 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. (2012). 7, 343348. After the accident, Gage's personality was said to have changed as a result of the damage the frontal lobe of his brain. Front. Neurosci. 8:276. doi: 10.3389/fnins.2014.00276, Bryck, R. L., and Fisher, P. A. Psychol. Part of the problem is that neuroscience evidence is genuinely mind boggling. The essential neuro claim made by his team was that Mr. Weinstein's arachnoid cyst impaired his rationality. Neuroevidence such as brain scans have several strengths. The impoverished brain: disparities in maternal education affect the neural response to sound. 6:238. doi: 10.3389/fnhum.2012.00238, Lipina, S., Segretin, S., Hermida, J., Prats, L., Fracchia, C., Camelo, J. L., et al. Trends Cogn. Modern neuropsychological tests are well characterized in terms of specificity, sensitivity, and predictive values. It is of increasing interest in the courtroom as well, and each year the number of cases using neuroscience-based evidence rises.2 The reasons for this are clear enough. Nat. Psychol. . A strength of the biological approach is that it provides clear predictions, for example, about the effects of neurotransmitters or the behaviors of people who are genetically related. Neurosci. doi: 10.1523/JNEUROSCI.4812-10.2010, Beaver, K. M., Wright, J. P., DeLisi, M., and Vaughn, M. G. (2012). Neurosci. (2014). Culturally, neuroscience is a currency that enjoys very high capital, and public fascination with neuroscience is evident in the news and popular culture.1 Neuroscience is cool: prestigious, high-tech, complex, philosophically rich, and beautiful. At first glance, this assertion seems reasonable. Sensitive periods in functional brain development: problems and prospects. Presciently, in 2006 Morse identified signs of a cognitive pathology he labeled brain overclaim syndrome (BOS). Front. (2013). Front. For instance, Brito and Noble (2014) have proposed early linguistic environment and stress as the candidate mechanisms through which poverty influences structural (i.e., language hemisphere, hippocampus, amygdala and prefrontal cortex) and functional (i.e., language, memory, social-emotional processing, cognitive control, self-regulation) brain development, based on recent findings considering different systems and levels of organization. 67, 87100. 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. Thus, neuroscientific evidence generated during the last decade in the study of childhood poverty has helped to identify the early linguistic environment and the regulation of stress as two main aspects to consider in dealing with the conceptual and methodological challenges, and as future directions in the area. Perhaps this is inevitable, considering the vast complexity of our brains in comparison to the miniscule amount that we know. Finally, we find it important to improve the knowledge on the conceptualization of childhood poverty in terms of how children experience deprivation, and the generation of innovative ways to operationalize it in suitable terms for neuroscientific approaches (Lipina et al., 2011). Neuropsychological testing, unlike neuroimaging for the purposes of cognitive assessment, is generally extensively validated and normed. The impact of poverty on the development of brain networks. Cognitive neuroscience combines the experimental strategies of cognitive psychology with various techniques to actually examine how brain function supports mental activities. 15) determined to be important to his needs.16. Neurobiological pathways linking socioeconomic position and health. Overview of Neuroscience Perspective Modern science is highly based on the structural and functional study of the brain. Furthermore, neuroscience currently lacks the evidence base to predict, based on neuroimaging, how likely cysts like Mr. Weinstein's cause impairment. Leading this research in normal humans are the new techniques of functional brain imaging: positron emission tomography (PET) and magnetic resonance imaging (MRI). Finally, in the interests of justice, when we recognize that neuroscience is being misused or misrepresented, we must be forthright in communicating this information to finders of fact. doi: 10.1016/j.dcn.2010.12.001, DAngiulli, A., Lipina, S. J., and Olesinska, A. All of this should help contribute with the identification and the better comprehension of the mechanisms of mediation of early adversity on brain development. doi: 10.1016/j.tics.2008.11.003, Hackman, D. A., Farah, M. J., and Meany, M. J. 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). For example, Ganzel et al. Critical period: a history of the transition from questions of when, to what, to how. (2014). Enhanced efficiency of the executive attention network after training in preschool children: immediate changes and effects after two months. (2010) have suggested that properties (i.e., magnitude, duration and chronicity), and types (e.g., social exclusion vs. physical threat) of stressors in early adverse developmental contexts modulate the impact on neural networks involved in acute and chronic responses to stress. This is a fundamental problem in the field and will only improve with better study designs that include larger sample sizes.40. However, Mr. Weinstein agreed to a plea deal of manslaughter, and the matter never went to trial. doi: 10.1523/JNEUROSCI.2102-13.2013, Smith, L. B., and Thelen, E. (2003). Things such as emotions, social pressures, environmental factors, childhood experiences, and cultural variables can also play a role in the formation of psychological problems. 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). (2011). Dev. Youth Stud. The biological residue of childhood poverty. doi: 10.1002/dev.20057, Jolles, D. D., and Crone, E. A. Acad. Acad. Sci. We will also finally get a good sense of the range of what brains in the general population look like and how they change over time. Differential susceptibility to rearing environment depending on dopamine-related genes: new evidence and a meta-analysis. 72, 450461. doi: 10.1002/dev.20058, Miller, G. E., and Chen, E. (2013). This means that the understanding of the role of the epigenome on the behavioral modifications driven by early experiences could contribute to our understanding of the relationship between childhood poverty and brain development. You may wonder why there are so many different psychological approaches and whether one approach is correct and another wrong. 84, 5875. Hum. Environmental enrichment and the brain. Disclosures of financial or other potential conflicts of interest: None. (2012). doi: 10.1016/j.neuroscience.2014.09.031, Holtmaat, A., and Svoboda, K. (2009). What are the links between maternal social status, hippocampal function and HPA axis function in children? Considering the opportunities and setbacks mentioned in the previous two sections, we propose a set of main points that require reconsideration and optimized approaches. Experience-dependent structural synaptic plasticity in the mammalian brain. The nervous system not only works to produce thoughts, emotions, and behavior, but also controls important body functions, like breathing. (2013). I have participated in several of these cases in my early career and have seen enough to report that there is trouble afoot. Relevance can be a concern as well, as it is often unclear how exactly certain neuropsychological test concepts, such as executive functioning, line up with legally relevant mental states and capacities. 15, 516527. These three types of evidence work well together because they can compensate for each other's relative weaknesses, while combining their strengths. Another technique invented in his laboratory, CLARITY,55 renders the brain transparent and, coupled with fluorescent molecular dyes, has allowed us to see for the first time intact brain circuits that traverse the whole brain. Nat. Neuroscience continues to experience stunning progress in several important areas. The study of how adverse environmental conditions (e.g., socioeconomic status (SES) or poverty) influence brain organization and reorganization during development includes different approaches. For example, people who go to funerals wear black, but it would be an error of logic to assume that all people who wear black go to funerals. 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. J. Neurosci. 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. human cognition - came to the fore of psychological thought during the mid twentieth century, overlooking the stimulus-response focus of the behaviourist approach. Commentary: neurocognitive consequences of socioeconomic disparities. Not only do researchers fail to detect real effects, but of more concern, they may also falsely determine null effects to be real. Strengths and weaknesses of biopsychology research. Neuroscience and Psychology offer a powerful insight as to what is happening in our brains and those of others. Strengths and Weaknesses of Humanistic Theory. (2011). Predictors of cognitive enhancement after training in preschoolers from diverse socioeconomic backgrounds. On the other hand, what should we do if the neuroevidence conflicts with behavioral evidence? A gradient of childhood self-control predicts health, wealth and public safety. ), a physician who recognized physiological psychology in the treatment of illnesses and linked the physical and psychological together. The developing brain: from theory to neuroimaging and back. Ct. 1992), Medical-legal inferences from functional neuroimaging evidence, Frye v. United States, 293 F. 1013 (D.C. Cir. For the testing specialist, the challenge is to ascertain the predictive value of a given brain defect on a proposed functional impairment. I encourage readers to view Mr. Weinstein's brain scans, which are widely available on the web and in several journal articles.27 The cyst is impressive, and based on what we know about the function of the frontal lobes, its placement certainly raises the possibility that it impaired his impulse control and rationality. 3, p 403). Inevitably, however, the curves overlap; some stroke patients will have better impulse control than some healthy controls, and some healthy subjects will have worse impulse control than some stroke patients. A limitation is that most biological explanations are reductionist. The CASP offers corrections to McGill and Busse's three critiques and clarifies the Association position that the assessment of students suspected of having a Specific Learning Disability involves a comprehensive evaluation that provides information regarding both environmental factors that include data on instruction and interventions as . Trust your gut is a piece of advice often thrown . Development as a dynamic system. (2009). Environmental noise exposure degrades normal listening processes. 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. doi: 10.1111/j.1467-8624.2011.01641.x, Evans, G. W., Li, D., and Whipple, S. S. (2013). Neurosci. Fourth, we suggest the development of innovative studies directed at analyzing plasticity of complex cognitive and emotional processes, and their respective windows of opportunities for intervention (Lipina and Colombo, 2009; DAngiulli et al., 2012; Lipina and Posner, 2012). Specifically, tasks involving language, cognitive control and memory demands have provided evidence that suggests that these systems may be the most frequently affected by SES adverse environments. U S A 102, 1493114936. U S A 111, 64436448. Sci. Advances in technology over the past 20 years have given modern neuro-researchers tools of unprecedented power to probe the workings of the most complex machine in the universe (as far as we know). I have witnessed neuroscience repeatedly misrepresented and misused. Training the brain: practical applications of neural plasticity from the intersection of cognitive neuroscience, developmentalpsychology and prevention science. doi: 10.1097/PSY.0b013e3181e1a23c, Goldin, A. P., Hermida, M. J., Shalom, D. E., Elias Costa, M., Lopez-Rosenfeld, M., Segretin, M. S., et al. Furthermore, we must understand the kinds of questions neuroscience will never be able to answer. doi: 10.1146/annurev.neuro.27.070203.144327, Hirase, H., and Shinohara, Y. Neural correlates of socioeconomic status in the developing human brain. Psychol. Front. 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. Knowing how things typically work can help shed light on what may happen when there are problems. Rev. 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. Functional MRI and PET do not measure brain activity directly, but rather signals that derive from neurovascular correlates of brain activity.
