注意对视听语义整合加工的影响

采用2×3的被试内实验设计,将注意条件和目标刺激类型作为实验变量,考察了指向不同感觉通道的注意对视听语义整合加工的不同影响。结果发现,只有在同时注意视觉和听觉刺激时,被试对语义一致的视听刺激反应最快,即产生冗余信号效应。而在选择性注意一个感觉通道时,语义一致的视听刺激并不具有加工优势。进一步分析发现,在同时注意视觉和听觉时语义一致视听刺激的加工优势源自于其视觉和听觉成分产生了整合。也就是说,只有在同时注意视觉和听觉时,语义一致视听刺激才会产生整合,语义不一致视听刺激不会产生整合。而在选择性注意一个感觉通道时,不论语义是否一致,视听刺激均不会产生整合。     

儿童对父母关爱的感知能力的发展

为了说明儿童能否感知到父母在情感、生理和行为三个方面的关爱,研究采用情境故事考察了幼儿园中班及小学二、四、六年级169名儿童对父母关爱的感知能力的发展特点。结果表明：随着年龄的增长,儿童对父母关爱的感知能力在不断发展;女孩对父母情感关爱的感知显著高于男孩;独生子女对父母生理关爱的感知显著高于非独生子女;高同伴接纳水平儿童对父母生理关爱的感知显著高于低同伴接纳水平儿童。     

Impact of Excessive Journal Self-Citations: A Case Study on the Folia Phoniatrica et Logopaedica Journal

There is an increasing trend towards assessing the scientific performance of researchers and institutions of higher learning in the form of journal publications and the associated citations. Currently, the journal impact factor (JIF) value is the most widely used measure for any academic contents. However, there are growing concerns for the unethical practices adopted by journal editors to manipulate the JIF computations. Recently, a Swiss journal, Folia Phoniatrica et Logopaedica which has a JIF value of 0.655 in the year 2006 registers a remarkable JIF increment (of 119%) to 1.439 in the year 2007. It is believed that the journal can achieve such a prominent JIF improvement by publishing a single editorial article that self-cited 66 of its own articles published either in the year 2005 or 2006. The journal has been revoked of any JIF value in the following year of 2008. Thus, it is interesting to review the possible alternative bibliographical trend for the journal should the self-cite event has been avoided, the circumstances leading to the decision by the editor to publish such an article and the possible ethical implications or lessons that can be derived from this incident.     

Effects of implicit power motive on the processing of anger faces: An event-related potential study

Implicit motives are one form of motivation that regulates cognitive and emotional processing. In this study, we investigated the impact of implicit power motive (nPower) on the processing of anger faces. Event-related potentials were recorded while high- and low-nPower individuals performed a face version of an emotion Stroop task comprised of anger and neutral faces. It was found that nPower does not modify early perceptual and attentional components (P2 and N2), but a later component is affected. Indeed, power-motivated participants showed enhanced P3/LPPs (Late positive potentials) amplitude compared to low-nPower subjects, in response to anger stimuli. These findings demonstrate that anger faces have greater salience for high-nPower individuals and are subject to a more salient, conscious processing.     

Neuroanatomy of childhood disruptive behavior disorders

Our aims were to (1) examine possible neuroanatomical abnormalities associated with the Disruptive Behavior Disorders (DBDs) as a group and (2) assess neuroanatomical anomalies specific to each DBD (i.e., conduct disorder [CD] and oppositional defiant disorder). Cortical thickness analysis and voxel-based morphometry were analyzed in 47 8-year-old boys (22 DBDs with and without CD and/or ODD and 25 healthy controls) from Magnetic Resonance Imaging brain scans. DBD symptoms were assessed using the Dominic-R. In DBD subjects relative to controls, we found (1) a decreased overall mean cortical thickness; (2) thinning of the cingulate, prefrontal and insular cortices; and (3) decreased gray matter density (GMd) in the same brain regions. We also found that scores on the Dominic-R were negatively correlated with GMd in the prefrontal and precuneus/superior temporal regions. There was a subdiagnostic main effect for CD, related to thinning of the middle/medial frontal, and for ODD in the left rectal/orbitofrontal. Findings suggest that thinning and decreased GMd of the insula disorganizes prefrontal circuits, diminishing the inhibitory influence of the prefrontal cortex on anger, aggression, cruelty, and impulsivity, and increasing a person's likelihood of aggressive behavior. These findings have implications for pathophysiologic models of the DBDs, their diagnostic classification system, and for designing more effective intervention programs.     

Parent-Child Engagement in Decision Making and the Development of Adolescent Affective Decision Capacity and Binge Drinking

The goal of this study was to investigate how parents’ engagement of their child in everyday decision-making influenced their adolescent’s development on two neuropsychological functions, namely, affective decision-making and working memory, and its effect on adolescent binge-drinking behavior.We conducted a longitudinal study of 192 Chinese adolescents. In 10th grade, the adolescents were tested for their affective decision-making ability using the Iowa Gambling Task (IGT) and working memory capacity using the Self-ordered Pointing Test (SOPT). Questionnaires were used to assess perceived parent-child engagement in decision-making, academic performance and drinking behavior. At one-year follow-up, the same neuropsychological tasks and questionnaires were repeated.Results indicate that working memory and academic performance were uninfluenced by parent-child engagement in decision-making. However, compared to adolescents whose parents made solitary decisions for them, adolescents engaged in everyday decision-making showed significant improvement on affective decision capacity and significantly less binge-drinking one year later.These findings suggest that parental engagement of children in everyday decision-making might foster the development of neurocognitive functioning relative to affective decision-making and reduce adolescent substance use behaviors.

儿童和少年情绪障碍相关社会心理因素探讨

儿童和少年情绪障碍是一组由家庭环境因素、认知倾向和个性心理等多种社会心理因素共同作用、相互影响的疾病。家庭是一个系统,对儿童和少年的心理和行为的塑造存在影响。家庭环境和个性因素是以认知倾向为中介产生对情绪的影响,家庭环境因素又影响了认知倾向的形成和个性的发展。从以上三个方面进行探讨,旨在为儿童和少年情绪障碍者的心理干预提供科学的理论依据。     

癌痛的治疗和人文关怀
