Differences in performance in CAMCOG-R domains between old and oldest old patients with Alzheimer’s disease

The purpose of this study is to evaluate the neuropsychological performance in a ≥90-year-old population with Alzheimer disease (AD) in comparison with younger elderly patients. We retrospectively studied all patients with AD attended in a specialized clinic between 1999 and 2011. Age, sex, educational level, and sensory loss data were collected. Neuropsychological evaluation included Mini-Mental State Examination and Global Deterioration Scale. We used the eight Cambridge Cognitive Assessment (CAMCOG-R) domains to evaluate and compare the neuropsychological performance in the younger than 90 years old (<90) and older than 90 years old (≥90) groups. We selected 2931 patients, 2897 <90 (98.83%) and 34 ≥90 years old (1.17%). The ≥90 group had significant lower punctuations in memory, praxis, and abstract thinking CAMOCG-R domains with 1.49, 0.75, and 0.58 less points, respectively, (p < 0.05). Neuropsychological characteristics of cognitive decline seem to be different in ≥90 compared to <90 years old patients. According to age, the biggest differences in the CAMCOG-R performance are in the memory, praxis, and abstract thinking domains.

Science‐based interviewing: Information elicitation

This article describes an ethical and effective science‐based model of interviewing. An initial planning phase assists the investigative team in separating facts from inferences, decreases the likelihood of errors based on cognitive biases, and prompts careful preparation of the environment. The interview begins with an explanation of why the subject is being questioned. The interviewer then metaphorically hands the interview over to the subject, making him the talker and the interviewer the listener. The interviewer engages in active listening, soliciting as much information from the subject as possible by deploying tactics that enhance memory based on science, including elements of the cognitive interview. Cues to deception are found in the details of the story, rather than in signs of anxiety or nonverbal behaviours, and by deploying Strategic Use of Evidence. This model has been shown to increase cooperation, decrease resistance, and provoke useful information in real‐world criminal interviews.     

Positive memory enhancement training for individuals with major depressive disorder

When in a negative mood state, individuals with major depressive disorder (MDD) may have difficulties recalling positive autobiographical memories in a manner that repairs that negative mood. Using cognitive bias modification techniques, investigators have successfully altered different aspects of cognition among individuals with MDD. However, little has been done to investigate the modification of positive autobiographical memory recall. This study examined the impact of a novel positive memory enhancement training (PMET) on the memories and subjective affective experiences of individuals with MDD (N = 27). Across a series of trials, participants first recalled a sad memory to elicit a negative mood state. They then recalled a happy memory and completed procedures to elicit a vivid, here-and-now quality of the memory. PMET procedures were hypothesized to promote mood repair via the recall of increasingly vivid and specific positive memories. PMET participants demonstrated improved memory specificity and greater perceived ability to “relive” positive memories. The procedures also repaired mood; PMET participants’ affect following recall of positive memories did not differ from control participants’ affect following recall of neutral memories. Results provide preliminary support for PMET as a method to improve the quality of positive memories and facilitate emotion regulation in MDD.     

谣言传播的情境、内容、传播者与受众特征及相关认知神经科学研究

什么样的谣言更容易获取信任、得到传播？面对谣言,为何有人理性批判,有人则毫不犹豫地点“赞”、转发？这是大众和研究者们共同关注的问题。本文主要从情境、内容特征、传播者与受众特征这三个维度论述了影响谣言传播的因素。从情境特征来看,谣言在模糊且具有潜在威胁的情境中更易传播,封闭的舆论场也助长了谣言传播;从内容特征来看,包含适当情绪内容、针对特定对象的谣言更易得到传播;从传播者与受众特征来看,一方面,可靠消息源会增强人们的传播意愿;另一方面,受众的认知局限、人格特质、动机、价值观等,均可能造成认知偏差或歪曲,助长谣言传播。以往研究多采用问卷调查法,今后需要更多严格控制变量的实验研究,从行为和神经层面深入探讨谣言传播的机制。最后,社交媒体数据采集与分析技术的发展,尤其是计算传播学等交叉学科的发展,为谣言传播研究提供了新的思路和方法。     

情绪性记忆的定向遗忘效应

刺激的情绪性具有增强记忆的效果,那么,带有情绪信息的刺激对遗忘又会产生怎样的影响？已有研究从行为及认知神经机制层面探讨了情绪性刺激对定向遗忘效应的影响,但结果并不一致。总结已有文献发现,以情绪性刺激的材料类型、情绪效价、唤醒度和熟悉度为主的客观因素和以被试的情绪状态为主的主观因素均为影响定向遗忘效应产生及其稳定性的重要原因。这类研究是对有意遗忘研究领域的重要补充,也加深了人们对有意遗忘机制的理解。     

一种非参数化的Q矩阵估计方法：ICC-IR方法开发

摘要：相对于参数化的方法,本研究根据题目测量模式关系开发出ICC指标,并提出基于理想得分的ICC指标法进行Q矩阵估计。Monte Carlo模拟研究与实证研究发现（1）基于理想得分ICC指标法估计Q矩阵具有很好的效果,当属性个数越少、基础题个数越多,估计效果越好。（2）相对于以往方法——D2统计量的方法,ICC-IR法效果更好,并且是一种非参数化的方法,计算简单快捷。（3）实证数据分析表明,ICC-IR法估计的Q矩阵在模型拟合度上也优于D2统计量方法。     

A psychometric comparison of anxiety-relevant attention measures

Background and Objectives: Preferential attention to threat, emotional response inhibition, and attentional control each purportedly play a key role in anxiety disorders. Divergent psychometric properties among attention measures may produce differential detection of anxiety-related associations and treatment-related changes. However, no studies have directly compared the psychometric properties of these attention measures in the same sample.

Design: Eighty-five young adults (M?=?19.41 years, SD?=?1.47, 48 Females) completed a cognitive task battery and a subset of 60 participants (M?=?19.42 years, SD?=?1.48, 33 Females) completed the task battery again approximately two weeks later.

Method: To assess preferential attention to threat, emotional response inhibition, and attentional control, the cognitive task battery included a dot-probe task, emotion and gender Stroop tasks, and a flanker task. Tasks varied in how attention was directed and if emotional stimuli were included. Internal consistency and test-retest reliability were compared across measures.

Results: Within the same sample, internal consistency and reliability differed across attention measures. Explicit attention measures (emotional Stroop and flanker) exhibited stronger internal consistency and greater test-retest reliability compared to implicit measures (dot-probe and gender Stroop).

Conclusions: These results inform clinical research using attention measures to assess anxiety-related differences and treatment response.     

Relations between empathy and anxiety dimensions in inpatient adolescents

Background and objectives: A better understanding of the relationships between empathy and internalizing disorders is needed to plan therapeutic interventions for children and adolescents. Several studies have revealed positive relations of internalizing symptoms to personal distress and affective empathy. However, there is a lack of studies that take into account the multidimensional nature of anxiety in its relation to empathy.

Design: Structural equation modeling was used to test the moderated mediation model of the relations between empathy, depression and anxiety dimensions and the moderating role of gender on these associations in inpatient adolescents.

Method: A total of 403 inpatient adolescents aged 12–17 years completed the Basic Empathy Scale, the Multidimensional Anxiety Scale for Children, and the Beck Depression Inventory-II.

Results: Affective empathy was positively related to all the anxiety dimensions – most strongly to separation/panic and humiliation/rejection anxiety, whereas cognitive empathy was negatively related to social and separation/panic anxiety. Relations between affective and cognitive empathy and anxiety were partly mediated by depressive symptoms. No evidence of a moderating role of gender has been found.

Conclusions: Our results suggest that processes associated with empathy may play a role in the development or maintenance of anxiety symptoms.
