工作记忆训练:一个很有价值的研究方向

采用不同的训练方法对不同人群的工作记忆进行训练的研究发现,工作记忆能力可以通过训练提高。通过工作记忆训练,个体的阅读能力、智力水平等得到提升。工作记忆的训练还可以改变人类大脑的活动,而且对于特殊儿童临床症状的缓解有一定的作用。工作记忆训练的研究对原有的认知理论以及相关理论模型提出了挑战,为工作记忆训练运用于教育、临床治疗等领域提供了实证支持,也为理解工作记忆开辟了新的方向。未来的研究应致力于改进训练内容、完善训练形式与指标、探索一套与工作记忆缺陷个体临床治疗相结合的工作记忆训练系统。     

工作记忆训练的研究述评*

以往研究表明,工作记忆是一个资源有限的系统,但近年来大量研究发现工作记忆成绩可以通过训练提高。工作记忆训练是指针对低容量的个体进行针对存储系统或者中央执行系统各成分的训练,以提升个体工作记忆绩效及影响任务相关脑区的活动。来自认知神经科学的证据在评估工作记忆训练的效果上起到了重要作用。虽然目前该领域的研究已经取得一定的成绩,但是利用工作记忆训练来改善个体的工作记忆在具体的方法、训练成效等问题上还存在一定的争议。     

心理旋转训练对5~6岁儿童空间能力和数学能力的影响

采用2（时间：前测/后测）×2（分组：实验组/控制组）的两因素混合实验设计,考察心理旋转游戏训练对5~6岁儿童空间及数学能力的影响。基于心理旋转的可塑性以及空间能力与数学能力之间的密切关系设计心理旋转干预方案,将36名被试分为实验组和控制组进行为期8周共24次的干预研究。研究结果表明：（1）空间能力与数学能力之间显著正相关;（2）心理旋转游戏有效地提高了5~6岁儿童的空间能力和数学能力,该训练方案具有良好的即时效果。     

音乐训练对4~5岁幼儿普通话声调范畴感知能力的影响

已有研究表明, 音乐训练能提高成人对普通话声调范畴感知的能力, 此种训练能否增强幼儿对声调范畴感知的能力?训练效果是否受到训练时间长短的影响?本研究对幼儿园4~5岁幼儿进行音乐训练, 共40人, 分成音乐组和控制组, 每组各20人, 追踪考察音乐训练和训练时间长短对幼儿声调范畴感知能力提升的影响。实验采用前测-中测-后测设计, 对音乐组开展每周3次, 每次30分钟, 以小钟琴演奏为主的音乐训练; 控制组不进行任何有组织的训练活动。结果发现, 12个月音乐训练提升了幼儿对声调范畴感知的程度, 表现为音乐组幼儿范畴边界宽度显著小于控制组, 而训练6个月时, 该优势并不显著。此外, 12个月音乐训练还加强了幼儿区分范畴内刺激声学差异的敏感性, 而对范畴间刺激的区分能力无显著提高。本研究结果支持了音乐学习的歌剧理论(OPERA), 音乐训练具有跨域迁移作用, 可提升4~5岁幼儿对普通话声调范畴感知的能力, 但只有长期持续的训练才可能真正提高幼儿的音高精细化加工水平。     

Multicultural training practices in community psychology programs

Surveyed the directors of 56 community psychology graduate programs to assess multicultural training practices and attitudes. Although most program directors agreed that multicultural training is important in their mission to educate students, less than half the programs (48%) required their students to take any relevant course work and only half of the programs surveyed had any faculty who were members of an ethnic minority group and one third had only one such faculty member. Furthermore, less than half the programs had a combination of training opportunities in place to integrate classroom, research, and field experiences relevant to multicultural issues. Finally, only 23% of program directors believed their training programs were successful for most students, suggesting the need to improve training.     

EFFECTS OF A MULTIFACETED TRAINING PROCEDURE ON THE ACQUISITION AND GENERALIZATION OF SOCIAL BEHAVIORS IN LANGUAGE-DISABLED DEAF CHILDREN

Effects of a multifaceted training procedure were assessed on the acquisition and generalization of social behaviors with 9 language-disabled deaf children. The training procedure consisted of (a) child training and (b) supervision, feedback, and goal setting directed by teachers and residential staff. Target behaviors were turn waiting, initiating interaction, and interacting with others. Procedures to promote generality of effects and to determine the social validity of the procedures were used. Data were collected within a multiple baseline design across behaviors. Results showed a functional relationship between introduction of the training procedure and increases in percentage of appropriate target behaviors for all 9 children. The effects were maintained throughout a 5- to 10-week follow-up period.     

Mirrors, Clocks, Maps, and Music: A South African Response to Family Therapy Supervision/Training

Once upon a time a training unit embarked upon a Journey. The Journey was to encompass a year's training and supervision in family therapy. Bags were packed to the brim with theory and training methods. One day the Unit left the bags behind to see what would happen if they travelled light and let the students bring their own luggage to the examination. Students were expected to describe their relationships with the interviewed families, and their training through a story. The great exam day came. Inspired students used innovative ideas and metaphors to describe the Journey. This article tells the story about these stories and the Unit's learning from them.     

Increasing accuracy and decreasing latency during clean intermittent self-catheterization procedures with young children.

We examined the effects of simulation training on performance of clean intermittent self-catheterization procedures with 2 young girls. Simulation training was conducted, after which independent performance was assessed within a multiple baseline design. The training resulted in increased accuracy and decreased latency for both girls.     

THE EFFECTS OF RESPONSE EFFICIENCY ON FUNCTIONALLY EQUIVALENT COMPETING BEHAVIORS

Three experiments addressed the role of response efficiency in the application of functional equivalence training. Functional equivalence training includes conducting a functional assessment of the problem behavior. Variables that predict and maintain the problem behavior are defined, and socially appropriate, functionally equivalent skills are identified and taught. The logic is that if the learner has a socially appropriate way to achieve the same function, he or she will be less likely to use problem behaviors. This study examined the role of response efficiency in functional equivalence training. Response efficiency was examined in terms of three variables: (a) physical effort, (b) schedule of reinforcement, and (c) the time delay between presentation of the discriminative stimulus and reinforcer delivery. Each of the three experiments involved a person who performed a set of problem behaviors and a functional assessment of the problem behaviors. A socially appropriate alternative response was taught, but this new response was less efficient than the problem behavior on one of the efficiency variables (effort, schedule, delay in time). The new behaviors did not compete successfully with the problem behaviors until a new, more efficient, alternative behavior was taught. These results are discussed in terms of our understanding of response covariation and the need in applied contexts to include response efficiency in any functional analysis assessment.
