具体实施方式
为了使得本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在 该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。
为了保持本公开实施例的以下说明清楚且简明，本公开省略了已知功能和已知部件的详细说明。
图1示出根据本公开实施例的记忆能力的训练方法的流程图，如图1所示，所述训练方法包括步骤S101至S108：
在步骤S101中，由处理器，呈现与记忆能力的训练相关的第一任务。具体说来，第一任务可以包括多种，在一些实施例中，第一任务可以为现有的与记忆能力的训练相关的任务，如言语工作记忆任务，在另一些实施例中，还可以自行设定第一任务，例如，以游戏的形式将文字、数字、图片等呈现给受训者，在一定时间后让受训者从当前的呈现内容中选出之前所呈现过的内容，或者让受训者默写出之前所呈现过的文字、数字等，在此不做具体限定。
在步骤S102中，获取由近红外光谱检测设备采集的受训者响应第一任务期间的第一脑区的第一血氧数据和第二脑区的第二血氧数据。其中，第一脑区与第二脑区均与记忆能力相关，受训者响应于第一任务时，第一脑区和第二脑区的对应的血氧数据也会相应的发生变化。由近红外光谱检测设备所采集的血氧数据的时间分辨率和空间分辨率较好，且抗运动干扰能力和抗电磁干扰能力较强，基于受训者在响应于第一任务期间的血氧数据来表征受训者的记忆能力的情况，可靠性较高，使得对受训者的记忆能力的训练效果较好。
在步骤S103中，由处理器，基于所获取的第一血氧数据和第二血氧数据来确定表征第一脑区和第二脑区的功能连接性的第一功能连接参数。具体说来，各个脑区之间具有功能连接性，与记忆能力相关的各个脑区之间的功能连接参数能够很好的表征受训者的记忆能力，通过对获取到的各个脑区对应的血氧数据进行处理来确定表征第一脑区和第二脑区的功能连接性的第一功能连接参数，能够很好的反映受训者在响应于第一任务期间的记忆力的情况。
在步骤S104中，由处理器，基于第一功能连接参数来确定并呈现第一反馈内容。受训者根据呈现的第一反馈内容以改善反馈第一反 馈内容为目标进行一下轮训练，从而实现对受训者的记忆能力的训练，可靠性高，训练效果较好。
在步骤S105中，由处理器，呈现与记忆能力的训练相关的第二任务。在一些实施例中，第一任务和第二任务可以为相同类型的任务，也可以为不同类型的任务。例如，呈现的任务为数字，在每一轮训练中都随机呈现数字给受训者，在一定时间后让受训者判断当前呈现的数字是否为之前呈现过的数字。又例如，可以分阶段对受训者的记忆能力进行训练，在第一阶段中的每一轮训练中呈现第一任务，其中，第一任务为数字，在根据呈现的反馈内容判断受训者的记忆能力得到一定程度的提升后，在第二阶段的训练中向受训者呈现较为较为复杂的图案，如此能够逐步的提升受训者的记忆能力，使得训练效果较好。
在步骤S106中，获取由近红外光谱检测设备采集的受训者根据第一反馈内容自我调节后再响应第二任务期间的第一脑区的第三血氧数据和第二脑区的第四血氧数据。在一些实施例中，可以以声音、字幕等形式提示受训者进行自我调节，在第二任务期间尽可能的去改善反馈内容，以实现对受训者的记忆能力的训练。
在步骤S107中，由处理器，基于所获取的第三血氧数据和第四血氧数据来确定表征第一脑区和第二脑区的功能连接性的第二功能连接参数。
在步骤S108中，由处理器，基于第二功能连接参数来确定并呈现第二反馈内容。
在一些实施例中，反馈内容可以为分数、奖金等，以便于受训者理解记忆能力的训练情况，增加趣味性。
在一些实施例中，可以通过设定训练次数、训练时长等来控制对受训者的训练，例如，设置终止训练的次数，在受训者完成相应次数的训练后自动结束训练，不再呈现任务。在一些实施例中，还可以根据反馈内容来控制对受训者的训练，例如，反馈内容为分数，在分数达到一定数值时自动结束训练。
本公开的实施例所提供的记忆能力的训练方法，通过获取受训者在响应任务期间的各个脑区的血氧数据，基于该血氧数据确定各个脑 区之间的功能连接参数，进而确定反馈内容并将其呈现给受训者，以训练受训者的记忆能力，可靠性高，训练效果较好。
在一些实施例中，第一脑区和第二脑区选自由额叶脑区、顶叶脑区、额叶脑区的分区和顶叶脑区的分区构成的组，且彼此至少部分不同。具体说来，额叶脑区和顶叶脑区均与记忆能力密切相关，在一些实施例中，可以获取部分额叶脑区和部分顶叶脑区的血氧数据来确定功能连接参数，例如，根据获取的分别位于额叶脑区和顶叶脑区的两个信号通道的血氧数据来确定功能连接参数，计算量较少，节省资源。在一些实施例中，近红外光谱检测设备可以包括数个信号通道，数个信号通道均匀的布置并覆盖于全部的额叶脑区和顶叶脑区，处理器获取的额叶脑区的第一血氧数据和顶叶脑区的第二血氧数据可以为近红外光谱检测设备处理后的血氧数据，例如，第一血氧数据为红外光谱检测设备对额叶脑区的各个信号通道中对应采样点的血氧数据进行平均得到的血氧数据，第二血氧数据为红外光谱检测设备对顶叶脑区的各个信号通道中对应采样点的血氧数据进行平均得到的血氧数据，如此根据第一血氧数据和第二血氧数据确定额叶脑区和顶叶脑区的功能连接参数，进而根据该功能连接参数确定的反馈内容也更可靠，使得对受训者的记忆能力的训练效果也较好。
在一些实施例中，第一反馈内容和第二反馈内容中的各个反馈内容基于相应的功能连接参数与其基准值的差值来确定。其中，基准值的确定方法可以有多种。在一些实施例中，各个功能连接参数的基准值为如下的任何一种：功能连接参数的理论值；受训者属于的人群样本的功能连接参数的平均值；或者基于受训者在静息期间的第一脑区的第五血氧数据和第二脑区的第六血氧数据，并利用与第一功能连接参数相同的定义来确定的第三功能连接参数。具体的，可以人为设定功能连接参数的理论值并将其作为基准值，也可以通过获取受训者属于的人群样本在响应于任务期间的血氧数据，并基于该血氧数据来确定各个样本的功能连接参数，以及该人群样本的功能连接参数的平均值，并将该平均值作为基准值。在一些实施例中，还可以利用受训者在静息期间的各个脑区的血氧数据来确定第三功能连接参数，并将其作为基准值，其中，静息期间可以指受训者处于静息状态，具体的， 静息状态可以指受训者不进行脑力活动，处于相对放松、平静状态，例如，不对受训者呈现任何内容，或以文字、声音等形式提示受训者不进行思考，保持放松状态等。
在一些实施例中，第一反馈内容和第二反馈内容中的各个反馈内容是一定范围内的反馈分数。将反馈内容以分数的形式呈现给受训者，以便于受训者更好的理解其记忆能力的训练情况，并且能够提示受训者以改善反馈分数为目的进行下一轮的训练，提升训练效果。
在一些实施例中，第一功能连接参数和第二功能连接参数中的各个功能连接参数通过公式(1)和公式(2)来计算：
Figure PCTCN2019111806-appb-000005
Figure PCTCN2019111806-appb-000006
其中，i表示第一脑区，j表示第二脑区，k为采样点序号，K为采样点总数，，x i(k)为第一脑区i的第k个采样点的血氧浓度值，x j(k)为第二脑区j的第k个采样点的血氧浓度值，
Figure PCTCN2019111806-appb-000007
分别为任务期间的第一脑区i和第二脑区j的平均血氧浓度值，r ij为第一脑区i和第二脑区j的血氧数据之间的相关系数，Z为受训者响应任务期间的功能连接参数，r为与记忆能力相关的成对的脑区的血氧数据之间的相关系数。
在一些实施例中，第一反馈内容和第二反馈内容中的各个反馈内容通过公式(3)来确定：
Figure PCTCN2019111806-appb-000008
其中，Z base为所述受训者在静息期间的功能连接参数，Z为响应任务期间的功能连接参数，SD为所述受训者在所述静息期间的功能连接参数的标准差，Score为反馈分数。通过以上公式可以基于所获取的各个脑区的血氧数据确定表征各个脑区之间的功能连接性的功 能连接参数，由于血氧数据的时间分辨率和空间分辨率较好，且抗运动干扰能力和抗电磁干扰能力均较强，使得根据该功能连接参数确定的反馈内容的可靠性也较高，如此能够提升训练效果。
在一些实施例中，第一任务和第二任务被呈现多次，每次的任务为：交替且接续地在第一时间段内呈现单个子内容接着在第二时间段内黑屏，也就是使得第一时间段和第二时间段交替且接续地发生；当呈现的单个子内容与前n(n可以为任何自然数)个子内容相同时，由受试者经由输入装置予以响应。例如，单个子内容为字母，将6个不重复的字母以2秒的时长呈现给受训者，在2秒后进入黑屏状态，在黑屏10秒后再呈现单个或多个字母，在受训者确定当前呈现的字母与之前呈现的字母相同时，可以通过输入装置予以响应，其中，输入装置可以为键盘、鼠标等。
在一些实施例中，第一任务和第二任务被呈现多次，每次的任务包括记忆阶段、保持阶段和询问阶段，在记忆阶段内呈现多个不重复的子内容供受训者记忆，保持阶段内提示受训者保持对子内容的记忆，询问阶段内随机呈现单个字母让受训者判定该子内容是否呈现过。在一些实施例中，可以以字幕、声音等形式提示受训者保持对子内容的记忆，例如在保持阶段，以呈现“+”的形式提示受训者保持对字内容的记忆。
在一些实施例中，子内容选自由字母、数字、图案、图形和符号构成的组中的任何一种。在一些实施例中，可以根据记忆能力对受训者进行阶段性训练，例如，在第一训练阶段呈现的子内容为较为简单的数字，以供记忆能力相对较弱的受训者进行训练，在第二训练阶段呈现较为复杂的字母和数字的混合内容，以供记忆能力相对较强的受训者或经过第一训练阶段的训练后其记忆能力有所提升的受训者进行训练，如此可以更加个性化，使得对受训者的记忆能力的训练效果较好。
在一些实施例中，呈现第一任务和第二任务之前，设有休息阶段，以便在休息阶段内提供相应的反馈内容。在实时的持续反馈过程中，受训者必须同时处理任务和反馈结果，如此容易对受训者的训练造成干扰，通过在下一轮的任务呈现之前设置休息阶段来呈现反馈内容， 以使呈现任务和反馈内容在时间上是分离的，能够提高训练的可靠性，提升训练效果。
在一些实施例中，训练方法还包括：根据第一反馈内容和第二反馈内容对受训者进行奖惩。通过反馈内容对受训者进行奖惩促使受训者尽可能的在下一轮训练中保持较好的记忆力，以得到较当前反馈内容更好的反馈内容，如此在实现对受训者的记忆能力的训练的同时还增加了趣味性，有利于提升训练效果。
图2示出根据本公开实施例的记忆能力的训练装置200的结构示意图，如图2所示，本公开还提供了一种记忆能力的训练装置200，训练装置200包括：第一呈现模块210，其配置为呈现与记忆能力的训练相关的第一任务；第一获取模块220，其配置为获取由近红外光谱检测设备采集的受训者响应第一任务期间的第一脑区的第一血氧数据和第二脑区的第二血氧数据；第一确定模块230，其配置为基于所获取的第一血氧数据和第二血氧数据来确定表征第一脑区和第二脑区的功能连接性的第一功能连接参数；第二呈现模块240，其配置为基于第一功能连接参数来确定并呈现第一反馈内容；第三呈现模块250，其配置为呈现与记忆能力的训练相关的第二任务；第二获取模块260，其配置为获取由近红外光谱检测设备采集的受训者根据第一反馈内容自我调节后再响应第二任务期间的第一脑区的第三血氧数据和第二脑区的第四血氧数据；第二确定模块270，其配置为基于所获取的第三血氧数据和第四血氧数据来确定表征第一脑区和第二脑区的功能连接性的第二功能连接参数；第四呈现模块280，其配置为基于第二功能连接参数来确定并呈现第二反馈内容。
在一些实施例中，第一呈现模块210呈现的第一任务可以包括多种，例如，第一任务可以为现有的与记忆能力的训练相关的任务，如言语工作记忆任务，在另一些实施例中，还可以自行设定第一任务，例如，以游戏的形式将文字、数字、图片等呈现给受训者，在一定时间后让受训者从当前的呈现内容中选出之前所呈现过的内容，或者让受训者默写出之前所呈现过的文字、数字等，在此不做具体限定。
