認(rèn)知神經(jīng)心理學(xué)是認(rèn)知心理學(xué)的一個(gè)分支，其目的是了解大腦的結(jié)構(gòu)和功能如何與特定的心理過(guò)程相聯(lián)系。認(rèn)知心理學(xué)是一門研究心理過(guò)程如何影響我們儲(chǔ)存和產(chǎn)生新記憶、產(chǎn)生語(yǔ)言、識(shí)別人和物體的認(rèn)知能力，以及我們推理和解決問(wèn)題的能力的科學(xué)。認(rèn)知神經(jīng)心理學(xué)特別強(qiáng)調(diào)研究腦損傷或神經(jīng)疾病的認(rèn)知影響，以期推斷出正常認(rèn)知功能的模型。證據(jù)是基于對(duì)個(gè)別腦損傷患者的案例研究，這些患者的腦區(qū)存在缺陷，而患者則表現(xiàn)出雙重離解。雙解離包括兩名患者和兩項(xiàng)任務(wù)。一名患者在一項(xiàng)任務(wù)中受損，而另一名患者在另一項(xiàng)任務(wù)中正常，而另一名患者在第一項(xiàng)任務(wù)中正常，在另一項(xiàng)任務(wù)中受損。例如，患者A在閱讀印刷文字時(shí)表現(xiàn)較差，而在理解口語(yǔ)文字時(shí)表現(xiàn)正常;患者B在理解書面文字時(shí)表現(xiàn)正常，而在理解口語(yǔ)文字時(shí)表現(xiàn)較差?？茖W(xué)家可以解釋這些信息來(lái)解釋單詞理解是如何有一個(gè)單一的認(rèn)知模塊的。從這些研究中，研究人員推斷大腦的不同區(qū)域是高度專門化的。認(rèn)知神經(jīng)心理學(xué)可與認(rèn)知神經(jīng)科學(xué)區(qū)分開(kāi)來(lái)，認(rèn)知神經(jīng)科學(xué)也對(duì)腦損傷患者感興趣，但特別關(guān)注揭示認(rèn)知過(guò)程背后的神經(jīng)機(jī)制

Cognitive neuropsychology is a branch of cognitive psychology that aims to understand how the structure and function of the brain relates to specific psychological processes. Cognitive psychology is the science that looks at how mental processes are responsible for our cognitive abilities to store and produce new memories, produce language, recognize people and objects, as well as our ability to reason and problem solve. Cognitive neuropsychology places a particular emphasis on studying the cognitive effects of brain injury or neurological illness with a view to inferring models of normal cognitive functioning. Evidence is based on case studies of individual brain damaged patients who show deficits in brain areas and from patients who exhibit double dissociations. Double dissociations involve two patients and two tasks. One patient is impaired at one task but normal on the other, while the other patient is normal on the first task and impaired on the other. For example, patient A would be poor at reading printed words while still being normal at understanding spoken words, while the patient B would be normal at understanding written words and be poor at understanding spoken words. Scientists can interpret this information to explain how there is a single cognitive module for word comprehension. From studies like these, researchers infer that different areas of the brain are highly specialised. Cognitive neuropsychology can be distinguished from cognitive neuroscience, which is also interested in brain damaged patients, but is particularly focused on uncovering the neural mechanisms underlying cognitive processes
