意识的四个要素理论

基于实验事实 ,提出了意识内部结构的观念。按照本文提出的意识的四个要素理论 ,意识由意识的四个要素及它们之间的相互作用组成。意识的四个要素是意识觉醒、意识内容、意识指向和意识感情。讨论了意识四个要素的脑机制     

情绪智力的基础：情绪觉察的研究现状与展望

情绪觉察作为情绪智力的重要基础,指的是识别与描述自己和他人情绪的能力,对个体的心理健康,人际交往具有重要意义。为系统考察情绪觉察的研究现状,采用定性和定量相结合的方式回顾以往研究,即先采用文献计量学的方法定量分析该领域研究的概况,然后在此基础上,对研究的具体内容从概念界定、测量工具、神经基础、相关因素和干预研究五个方面作进一步系统梳理。最后,对以往研究进行了总结和展望,以期为今后研究提供借鉴。     

小学生课文图式意识、图式操作策略与图式行为关系的研究

本研究采用课文分析法对松原市蒙来小学１８４名五年级学生进行了实验研究,探讨了课文图式意识、图式操作策略及图式行为之间的关系。结果发现,它们三者之间的关系既相互依赖,又存在差异。课文图式操作策略对图式行为的影响比图式意识对其影响要大。说明提高学生课文图式能力的主要途径是加强图式操作策略的训练和培养。     

小学低段汉字识别和听写的发展轨迹：语素意识的预测作用

汉字识别和听写是字词水平上两项重要的读写技能。对127名一年级儿童进行了两年4个时间点的追踪调查,通过测查儿童的一般认知能力、语音意识、正字法意识和语素意识(包括同音语素意识、复合语素意识),探讨影响儿童汉字识别和听写发展的因素。利用潜变量增长模型,结果发现:(1)汉字识别呈线性发展趋势,听写呈先快后慢的非线性发展趋势,二者均存在补偿效应;(2)语素意识显著预测了汉字识别的起始水平和发展速度,但语素意识对听写的起始水平和发展速度均不具有显著的预测作用。研究结果表明儿童入学初始的汉字识别和听写水平并不决定后期的发展速度;语素意识对儿童汉字识别和听写发展的作用不同。     

急性应激损伤错误监控与错误后调整

生活中,个体会时时关注自己的行为结果并及时做出调整以适应环境的变化。但在应激下个体能否有效地监控行为并做出适应性调整依然未知。本研究招募了52名男性大学生被试,将其随机分入应激组与控制组,采用特里尔社会应激测试(Trier Social Stress Test, TSST)诱发个体的应激反应,并结合错误意识任务(Error Awareness Task,EAT)探索个体急性应激下的错误监控与错误后调整过程。应激指标的结果显示应激组个体在应激任务后唾液皮质醇、心率、应激感知自我报告和负性情绪均显著高于控制组,表明急性应激的诱发是成功的。行为结果显示应激组的错误意识正确率显著低于控制组,错误意识反应时显著短于控制组;进一步地,应激组个体在意识到错误之后的试次上正确率显著低于未意识到错误之后的试次,并且应激组个体在意识到错误之后的试次上正确率低于控制组。结果表明急性应激降低了个体对错误反应的监控水平,即便在辨别出错误反应的情况下,个体的行为监控与调节也更差。本研究说明急性应激会损伤行为监控系统,导致个体的行为适应性下降。     

未意识到错误影响错误后调整的电生理证据

现有研究一致认为意识到错误可引起错误后调整,但是未意识到错误能否促使个体进行错误后调整尚存争议。本实验采用基于go/no-go范式的错误意识任务考察上述问题,并根据被试对自己按键反应正误主观报告将no-go错误反应分为意识到错误和未意识到错误。行为结果发现,意识到错误和未意识到错误后正确率均显著高于正确击中试次(正确go试次)后正确率;但是,意识到错误后试次反应时显著快于正确击中后反应时,未意识到错误后反应时显著慢于正确击中后反应时。该结果表明两类错误均优化了错误后行为表现,但是意识到错误后被试调整速度加快,未意识到错误后被试调整速度减慢。进而,时频分析发现意识到错误相较于未意识到错误诱发显著更强的alpha波能量。并且,前者在错误意识主观报告前已诱发alpha波,后者在错误意识主观报告反应后诱发alpha波。该结果表明意识到错误一直处于持续的注意监控中,而未意识到错误是任务引起的暂时注意控制。因此,本实验说明错误意识影响错误后调整,意识到错误可能采用类似主动性控制的策略调节错误后行为,而未意识到错误可能采用类似反应性控制的策略调节错误后行为。     

CONSCIOUSNESS AND THE MACHINE

Abstract. We consider only the relationship of consciousness to physical reality, whether physical reality is interpreted as the brain, artificial intelligence, or the universe as a whole. The difficulties with starting the analysis with physical reality on the one hand and with consciousness on the other are delineated. We consider how one may derive from the other. Concepts of universal or pure consciousness versus local or ego consciousness are explored with the possibility that consciousness may be physically creative. We examine whether artificial intelligence can possess consciousness as an extension of the interrelationship between consciousness and the brain or material reality.     

Instructed versus shaped human verbal behavior: Interactions with nonverbal responding

Undergraduate students' presses on left and right buttons occasionally made available points exchangeable for money. Blue lights over the buttons were correlated with multiple random-ratio random-interval components; usually, the random-ratio schedule was assigned to the left button and the random-interval to the right. During interruptions on the multiple schedule, students filled out sentence-completion guess sheets (e.g., The way to earn points with the left button is to...). For different groups, guesses were shaped with differential points also worth money (e.g., successive approximations to “press fast” for the left button), or were instructed (e.g., Write “press slowly” for the left button), or were simply collected. Control of rate of pressing by guesses was examined in individual cases by reversing shaped or instructed guesses, by instructing pressing rates, and/or by reversing multiple-schedule contingencies. Shaped guesses produced guess-consistent pressing even when guessed rates opposed those characteristic of the contingencies (e.g., slow random-ratio and fast random-interval rates), whereas guesses and rates of pressing rarely corresponded after unsuccessful shaping of guesses or when guessing had no differential consequences. Instructed guesses and pressing were inconsistently related. In other words, when verbal responses were shaped (contingency-governed), they controlled nonverbal responding. When they were instructed (rule-governed), their control of nonverbal responding was inconsistent: the verbal behavior sometimes controlled, sometimes was controlled by, and sometimes was independent of the nonverbal behavior.     

Adaptive warning signals adjusted to driver passenger conversation: Impact of system awareness on behavioral adaptations

The study investigated behavioral adaptation caused by warning signals that adaptively support drivers engaged in a passenger conversation. Novel advanced driver assistance systems (ADAS) could monitor the driver state to provide warnings adjusted to the driver’s current need for support. While first research indicates positive effects of dynamically adjusting ADAS, the overall safety potential of such adaptive systems remains unclear as little is known about adverse behavioral effects. Occasional inappropriate support due to an incorrect prediction of the current driver state might lead to critical situations when drivers are aware of the adaptive nature of the system and thus rely on the expected system behavior. To better understand behavioral adaptation to dynamically adjusting warnings, 46 participants driving on a test track reacted to two types of warnings (auditory, vibrotactile-auditory) while engaging in driver-passenger conversation or not. In a compensating warning strategy, vibrotactile-auditory warnings were displayed during conversations and auditory warnings in situations without conversation. This strategy was compared to a non-compensating warning strategy in which these assignments were reversed. The impact of behavioral adaptation was measured by considering reactions to simulated failures of these strategies. The role of system awareness for behavioral adaptation was investigated by manipulating awareness of these warning strategies across groups. We found that vibrotactile-auditory warnings reduced the detrimental effects of conversation on reaction times. Crucially, adverse behavioral adaptation was observed whenever an expected vibrotactile-auditory warning was replaced by an auditory warning but this effect was restricted to drivers in the awareness group. The results show that adaptive warning signals optimize the effectiveness of warnings during driver-passenger conversation but adverse behavioral adaptation develops when drivers are aware of the underlying warning strategy. This implies that future adaptive systems are less likely to be associated with behavioral adaptation if the adaptive nature of the system remains unnoticeable to the driver. Our findings could be used for developing and optimizing user-centered ADAS.
