汉语发展性阅读障碍儿童的视知觉学习*

研究采用知觉学习经典范式中的视觉搜索任务探讨汉语发展性阅读障碍儿童的知觉学习过程。研究考察了阅读障碍儿童与正常儿童在简单搜索任务、复杂搜索任务和限制时间的复杂搜索任务上的知觉学习特点。结果发现,阅读障碍儿童在复杂搜索任务中初始搜索时间显著长于正常控制组;在限制时间的复杂搜索任务中更进一步发现阅读障碍儿童的反应正确率显著低于正常控制组儿童;而且两组儿童视觉搜索任务的正确率与汉语阅读的识字量成绩存在显著相关。上述结果表明,汉语发展性阅读障碍儿童存在复杂搜索的知觉学习缺陷,这种缺陷可能在某种程度上与儿童的阅读技能发展有关。     

Psychological implications of a vision disorder

The paper discusses how the condition of crossed‐eyes affects a baby's eye contact with mother and potentially results in the loss of a vital emotional connection with her during the earliest days of life. This loss may contribute to a rupture that arrests emotional development at a deep psychic level. It is suggested that, in the same way as premature separation, the rupture can precipitate a ‘fusional complex’, a defence that develops to protect the infant against psychotic anxieties. The paper proposes that psychological development atrophies in this place and creates a blind spot. These ideas are explored through analytic theory and developmental literature. The dreams of a patient and his art are used to illustrate a 10‐year ‘alchemical’ process of bringing repressed material into consciousness and transformation. Healing the psychological wounds of deficits in early eye contact may be found to bring sight to a blind spot that was created by the nature of the condition itself.     

McGurk Effect in Gender Identification: Vision Trumps Audition in Voice Judgments

Demonstrations of non-speech McGurk effects are rare, mostly limited to emotion identification, and sometimes not considered true analogues. We presented videos of males and females singing a single syllable on the same pitch and asked participants to indicate the true range of the voice–soprano, alto, tenor, or bass. For one group of participants, the gender shown on the video matched the gender of the voice heard, and for the other group they were mismatched. Soprano or alto responses were interpreted as “female voice” decisions and tenor or bass responses as “male voice” decisions. Identification of the voice gender was 100% correct in the preceding audio-only condition. However, whereas performance was also 100% correct in the matched video/audio condition, it was only 31% correct in the mismatched video/audio condition. Thus, the visual gender information overrode the voice gender identification, showing a robust non-speech McGurk effect.     

Semantic and Syntactic Associations During Word Search Modulate the Relationship Between Attention and Subsequent Memory

Two experiments were conducted to investigate how linguistic information influences attention allocation in visual search and memory for words. In Experiment 1, participants searched for the synonym of a cue word among five words. The distractors included one antonym and three unrelated words. In Experiment 2, participants were asked to judge whether the five words presented on the screen comprise a valid sentence. The relationships among words were sentential, semantically related or unrelated. A memory recognition task followed. Results in both experiments showed that linguistically related words produced better memory performance. We also found that there were significant interactions between linguistic relation conditions and memorization on eye-movement measures, indicating that good memory for words relied on frequent and long fixations during search in the unrelated condition but to a much lesser extent in linguistically related conditions. We conclude that semantic and syntactic associations attenuate the link between overt attention allocation and subsequent memory performance, suggesting that linguistic relatedness can somewhat compensate for a relative lack of attention during word search.     

Visual arts in counselling adults with depressive disorders

This study provides a better understanding of using visual arts in counselling adults with depressive disorders. Three in-depth case studies were conducted in the counselling unit of a mental health hospital in Malaysia. Both qualitative and quantitative research methods were applied to explore three adult participants’ counselling experiences. They attended six individual counselling sessions, which included four art-making activities, and two after-session interviews, for approximately two months. Interpretative Phenomenological Analysis was used to analyse the qualitative data. The findings showed that through the therapeutic use of visual arts, the participants were able to explore and express various emotions, face their problems, communicate better with themselves and the counsellor, achieve a deeper self-understanding, and make meaningful progress in counselling, even though some of them experienced a sense of uncertainty at the beginning of some art-making activities.     

The contribution of visual processing to academic achievement in adolescents born extremely preterm or extremely low birth weight

Children born extremely preterm (EP, <28 weeks) and/or extremely low birth weight (ELBW, <1000 g) have more academic deficiencies than their term-born peers, which may be due to problems with visual processing. The aim of this study is to determine (1) if visual processing is related to poor academic outcomes in EP/ELBW adolescents, and (2) how much of the variance in academic achievement in EP/ELBW adolescents is explained by visual processing ability after controlling for perinatal risk factors and other known contributors to academic performance, particularly attention and working memory. A geographically determined cohort of 228 surviving EP/ELBW adolescents (mean age 17 years) was studied. The relationships between measures of visual processing (visual acuity, binocular stereopsis, eye convergence, and visual perception) and academic achievement were explored within the EP/ELBW group. Analyses were repeated controlling for perinatal and social risk, and measures of attention and working memory. It was found that visual acuity, convergence and visual perception are related to scores for academic achievement on univariable regression analyses. After controlling for potential confounds (perinatal and social risk, working memory and attention), visual acuity, convergence and visual perception remained associated with reading and math computation, but only convergence and visual perception are related to spelling. The additional variance explained by visual processing is up to 6.6% for reading, 2.7% for spelling, and 2.2% for math computation. None of the visual processing variables or visual motor integration are associated with handwriting on multivariable analysis. Working memory is generally a stronger predictor of reading, spelling, and math computation than visual processing. It was concluded that visual processing difficulties are significantly related to academic outcomes in EP/ELBW adolescents; therefore, specific attention should be paid to academic remediation strategies incorporating the management of working memory and visual processing in EP/ELBW children.     

网络成瘾倾向者对负性表情注意的脱离困难

采用Young编制的IAT量表从382名青少年中筛选出网络成瘾倾向者15名,非网络成瘾控制组被试18名,利用视觉搜索范式比较了两组被试对真人面孔和卡通面孔表情的注意偏向差异。结果表明：（1）在注意快速定向阶段,当要求被试快速准确地从中性面孔矩阵中搜索高兴或者愤怒面孔时,相较于控制组被试,网络成瘾倾向者搜索愤怒面孔更迅速,尤其表现为对卡通愤怒面孔的快速定向优势;（2）在注意的维持和脱离阶段,当在愤怒或高兴面孔矩阵中搜索中性面孔时,相较于控制组被试,网络成瘾倾向者在更具威胁性的真人愤怒面孔矩阵中最难脱离。结论：网络成瘾倾向者具有负性注意偏向特点,表现为对负性表情具有快速定向和解脱困难。且相较于控制组被试,网络成瘾倾向者对卡通面孔注意定向更快而更难从真人愤怒面孔矩阵中脱离,也说明了其注意偏向主要为对负性信息的注意解除困难。     

Bridging novelty and familiarity-based recognition memory: A matter of timing

Novelty detection is essential to adapt to changes. However, the relationship between novelty detection and visual recognition memory remains unclear. To characterize the temporal dynamics of novelty and its connection to familiarity, we probed early behavioural performance of novelty and familiarity in 31 participants using a speeded go/no-go recognition task with a 600-ms response deadline. Responses to familiarity and novelty produced symmetrical biases and correlated accuracies and biases, but novelty decisions were less accurate and had slower minimal reaction times (410?ms). These processes thus appear to be independent, as suggested by a more efficient system in the case of familiarity, but with common factors bringing overlapping contributions to both processes. This may possibly be explained by the more fluent processing of repeated stimuli, but with familiarity and novelty potentially relying on one decision criterion, as suggested by the correlated and remarkably symmetrical biases. This study supports models that conceptualize novelty and familiarity decisions as two partly overlapping processes.     

Diversity and Dance: Exploring the Therapeutic Implications of World Dance

This phenomenological study examined the potential power of world dance as a therapeutic tool. The lived experiences of adult females (N = 16) were explored to understand the purposive essence of dance and subsequent benefits to mental health. Findings revealed 15 themes in total: 11 themes highlighted potential benefits of world dance, such as social support and stress relief, and four themes noted potential obstacles to using world dance as a therapeutic tool, such as access or finances. Implications for using world dance within creative counseling practice are provided.     

Using Visual Journaling in Individual Counseling: A Case Example

The purpose of this article is to describe and illustrate through a hypothetical case example how visual journaling, a form of expressive arts counseling, can be adapted for use in individual counseling. Counselors may consider using visual journaling as a counseling intervention when working with clients who may not have words for what they are feeling or experiencing, and for clients who tend to be very analytical. Visual journaling can be a way to bypass the intellect and give clients another way to access their experience.
