Same face,same place,different memory: manner of presentation modulates the associative deficit in older adults

One of the more severe and consequential memory impairments experienced by older adults is the loss of the ability to form and remember associations. Although the associative deficit is often assumed to be unitary, memory episodes may contain different types of associations (e.g., item–item, item–context). Research in younger adults suggests that these different association types may involve different neural mechanisms. This raises the possibility that different association types are not equally affected by aging. In order to investigate this, the current study directly compared memory across item–item and item–context associations in younger and older adults by manipulating the manner of presentation of the associations. Results indicate that the associative deficit in aging is not uniform and that aging has a greater impact on item–context compared to item–item associations. The results have implications for theories of associative memory, age-related cognitive decline, and the functional organization of the medial temporal lobe in aging.     

Learning to teach through video playback: student teachers confronting their own practice

The aim of this study was to examine the use of video playback with student teachers to promote teacher learning and to analyse patterns of reflection. A total of 14 student teachers video recorded their lessons in the practice setting and later confronted their performance, facing their videotaped lesson during the course of an interview with their university supervisor. The interviews were then transcribed and coded. Our results indicate that video playback facilitates student teacher learning and that the quality of reflection ranges from routine to dialogic. This suggests that further research into how to elicit higher levels of reflection is needed. The role of the supervisor in promoting deeper thinking should be further examined.     

Seeing Is Believing: Using Video Feedback in Cognitive Therapy for Social Anxiety Disorder

Distorted negative self-images and impressions appear to play a key role in maintaining Social Anxiety Disorder (SAD). In previous research, McManus et al. (2009) found that video feedback can help people undergoing cognitive therapy for SAD (CT-SAD) to develop a more realistic impression of how they appear to others, and this was associated with significant improvement in their social anxiety. In this paper we first present new data from 47 patients that confirms the value of video feedback. Ninety-eighty percent of the patients indicated that they came across more favorably than they had predicted after viewing a video of their social interactions. Significant reductions in social anxiety were observed during the following week and these reductions were larger than those observed after control periods. Comparison with our earlier data (McManus et al., 2009) suggests we may have improved the effectiveness of video feedback by refining and developing our procedures over time. The second part of the paper outlines our current strategies for maximizing the impact of video feedback. The strategies have evolved in order to help patients with SAD overcome a range of processing biases that could otherwise make it difficult for them to spot discrepancies between their negative self-imagery and the way they appear on video.     

Using video-supported reflection in peer groups to increase instructional effectiveness

This article reports upon the findings of research that explored change in teachers’ reflective thought and practice on a core set of complex teaching practices after the teachers participated in video-supported reflection model. Five 4th–7th grade teachers participated in the model that paired video-supported collaborative reflection with a research-based observation instrument, Classroom Assessment Scoring System (CLASS). Classroom observation data was collected by video and scored to determine change in teaching practice. All video-supported collaborative dialogue sessions between peers were videotaped and transcribed. Findings point to the developmental process necessary when learning to critically reflect upon and enact complex instructional practices that are not already prominent in practice. Individual development of practice progressed as the collaborative dialogue group expanded their capacity for describing, understanding, and evaluating practice based upon a new schema of effective practice, intentionally enacting change resulting in significant increases in teacher performance.     

自闭症幼儿的视觉性自我认知实验研究

通过对平均心理年龄为23个月的6名自闭症幼儿的实验研究．甄别他们是否能从视觉上进行自我与他人的分化认知并进一步探索自闭症幼儿对镜像自我认知与录像自我认知上的差异;以秒为单位．对实验结果和过程进行了编码分析。结果表明：这6名幼儿在看自己的录像时,比看同伴的表现出更多的关注和喜悦;对录像的自我进行认知寸表现出更大的关注和积极情绪。由此推断他们已具有初步的自我认知。     

Behavioral intervention to treat selective mutism across multiple social situations and community settings

We evaluated a behavioral intervention for a 9-year-old girl with selective mutism. The intervention consisted of role play and video self-modeling. The frequency of spoken initiations, responses to questions, and communication breakdowns was measured during three social situations (i.e., ordering in a restaurant, meeting new adults, and playing with new children) and in three community settings. Results demonstrated increases in spoken initiations and responses and decreases in communication breakdowns across all situations and settings.     

From blooming,buzzing confusion to media literacy: The early development of television viewing

Television comprehension is a surprisingly demanding task for very young children. Based on a task analysis of television viewing and review of research, we suggest that by 6 months of age, infants can identify objects and people on screen. By 24 months they can comprehend and imitate simple actions contained in single shots and begin to integrate information across shots. Toddlers nevertheless suffer from the video deficit whereby their comprehension is less than from equivalent real life displays. During the preschool years they learn much of the grammar of filmic montage and can comprehend straightforward narrative productions. Essentially adult comprehension appears to be in place by 13 years of age.     

Group‐based evaluations for pupil‐on‐teacher violence: The impact of teacher intervention strategy

Although extreme violence to teachers is rare, the fact remains that in the UK, 29% of teachers report having been physically assaulted by a pupil (ATL, 2008a ). The ways in which responsibility for such assaults are attributed can have legal, educational and managerial implications. In the current study, teachers (N = 66), pupils (N = 68) and parents (N = 64) from a large secondary school in the UK read an incident report form outlining an incident depicting a pupil physically assaulting a teacher. The incident report was manipulated such that, prior to being assaulted, the teacher had either separated the assailant pupil from another pupil using a physical or non‐physical intervention. Results revealed that participating parents' and teachers' evaluations of the assailant's parents and the teacher differed from those of pupils in several ways. The results are discussed in terms of group‐based responsibility for deviant behaviour and implications for teacher behaviour in response to pupil on teacher violence.

Predicting the Early Developmental Course of Symptoms of Attention Deficit Hyperactivity Disorder

Data from the National Institute of Child Health and Human Development Study of Early Child Care were examined to test whether: attention deficit/hyperactivity disorder (ADHD) symptoms remain stable from 54 months through early elementary school; behavioral inhibition and attention deficits assessed at 54 months predict ADHD symptoms in elementary school, even after controlling for their temporal stability; and early behavioral inhibition and attention deficits moderate the longitudinal stability in ADHD symptoms. Data were examined using continuous and categorical measures of symptoms. Modest stability in ADHD symptoms from 54 months to third grade was found. Measures of inhibition and inattention predicted later teacher ratings uniquely, but no evidence was found for moderation. Measures of preschool behavioral inhibition also predicted “persistently at risk status” defined by elevated teacher ratings over time. Results are discussed in terms of executive and motivational facets of inhibition that may be related to early signs of ADHD.     

暴力电子游戏的短期脱敏效应：两种接触方式比较

比较主、被动接触暴力电子游戏的脱敏效应,以44名男性大学生为被试,利用生物反馈仪测量被试主动参与游戏或被动观看游戏录像前后,及随后观看暴力视频过程中皮电与心率的变化（脱敏效应的生理指标）。结果表明：（1）暴力电子游戏可以产生脱敏效应。接触游戏15分钟后,暴力游戏组观看暴力视频过程中皮电的增加值明显小于非暴力游戏组;（2）游戏的接触方式对于脱敏效应的程度无显著影响,但主动参与组对于游戏内容知觉到更高的愉快与更低的沮丧
