时间性前瞻记忆的练习效应及其人格差异

实验1和实验2分别探究在低难度和高难度进行中任务条件下是否存在TBPM的练习效应及其人格差异,结果发现无论在何种情况下,实验组的前瞻记忆成绩均显著高于控制组,说明TBPM的练习效应稳定存在;A-B型人格类型与组别交互作用均不显著,说明A型和B型人格在TBPM的练习效应上没有差异;实验组在总的时间监控次数和后期时间监控次数上均高于控制组,时间差均低于控制组,说明练习通过提高时间监控有效性和总的注意投入量来提高前瞻记忆成绩。     

中学生完成系列回忆任务错误类型发展的实验研究

本研究以初中一、三年级和高中二年级学生为被试,以三种类型的汉字(普通字、形似字和同音字)为实验材料,采用系列回忆任务的个别实验法,考察中学生完成系列回忆任务的错误类型特点。结果发现:1.各年级都出现了遗漏错误、侵入错误、移动错误和重复错误,其中移动错误随年级升高而减少且错误率最高。2.四种错误类型表现出不同的位置效应。3.同音字引起的错误率明显高于普通字和形似字。     

部件类型还是交错关系信息的习得促进问题解决？

本研究旨在探讨知觉组块中部件类型和空间交错关系信息的学习是否促进问题解决。研究采用学习-测试范式,71名有效被试（女性25名,平均年龄=20.51±2.35岁）先学习解答组块破解问题然后进行测试。研究分别在学习和测试阶段基于组块破解任务操纵了部件类型（汉字水平vs.笔画水平）和空间交错关系（交错vs.非交错）。学习阶段,被试分别在四组中完成组块破解练习;在测试阶段完成所有四组问题。研究发现,对交错关系信息的学习与利用相对于部件类型信息促进了问题解决：在涉及交错信息的测试任务上,涉及交错信息比非交错信息的学习条件解答率更高,反应时更短;反之则不是。然而部件类型则没有发现类似的促进效应。与此同时,交错关系信息的习得需要对任务的重复操作学习：涉及交错关系信息的组块破解学习成绩在不同任务间并不随时间推移而提高,但会随重复学习次数而提高。     

真实物体搜索中的视角依赖效应:来自眼动的证据

已有研究发现物体识别存在视角依赖效应,那么在真实物体搜索中是否也存在视角依赖效应呢?本研究采用物体阵列搜索任务,通过眼动技术探讨真实物体搜索中的视角依赖效应及其来源。结果发现:(1)图片提示的搜索绩效优于名称提示;(2)以名称提示时,常规视角的搜索绩效高于新异视角,与新异视角相比,以常规视角呈现的目标物体在扫描和确认阶段的注视点数较少且持续时间较短,表现出视角依赖效应;(3)以图片为提示时,搜索绩效与视角无关。由此可见,在以名称提示的物体搜索中,常规视角比新异视角条件下的注意引导更高效,对目标物体的确认也更快,扫描和确认阶段均存在视角依赖效应,支持目标模板的双功能理论。     

个体采纳与群体采纳：决策过程中的两类建议采纳行为

决策者借助外界的建议通常能够获得更好的决策结果, 但是个体和群体对待建议的态度和行为却不尽相同。基于已有研究, 阐述了个体和群体在建议采纳过程中的特点并分析了造成二者差异的因素, 主要包括二者在面对决策任务和外界建议时的不同表现。此外, 根据群体动力理论, 未来研究可以从群体的动力源因素(凝聚力, 驱动力, 耗散力)来解释和预测群体的建议采纳及其与个体建议采纳的差异, 以期为不同决策情景下决策人员的合理安排和配置提供参考。     

叠音姓名对人际知觉和态度的影响

基于刻板印象内容模型,通过三个实验考察了叠音姓名对人际知觉和态度的影响,并检验了性别特征的调节作用。研究结果表明:(1)叠音姓名会让人们觉得评价对象更像儿童,更温暖,但也更缺乏能力。(2)叠音姓名对人际知觉的影响受到姓名性别特征的调节。对于女性化姓名,叠音姓名对温暖和能力知觉的影响会削弱。(3)叠音姓名对人际态度的作用受到工作类型的影响。人们会觉得叠音姓名的人更适合从事服务性的工作,非叠音姓名的人更适合从事技术性的工作。     

The effects of different exercise types on visuospatial attention in the elderly

While the capability of visuospatial attention decreases with advanced aging, exercise is an effective primary prevention strategy to ward off the progression of such cognitive declines among the elderly. However, no studies have yet been conducted on the relationship between exercise type and visuospatial attention in the elderly. This study was thus carried out to explore the effects of open- and closed-skill exercise modes on visuospatial attention in the elderly using behavioral and cognitive electrophysiological measurements. Sixty elderly participants were divided into open-skill (n = 20), closed-skill (n = 20), or control (n = 20) groups according to their exercise-participation experience in the previous 24 months, and performed a visuospatial attention task with concomitant electrophysiological recording. The results showed that the two exercise groups (i.e., open- and closed-skill) exhibited shorter reaction times (RTs) and larger P3 amplitudes across conditions compared with the control group. Although the open- and closed-skill groups only showed approaching between-group significance on the RTs in the invalid condition and on the P3 amplitudes across conditions, only the open-skill group showed better inhibitory control of attention relative to the control group. These findings reveal the presence of neurocognitive effects on the visuospatial attention task in the two exercise groups, with significantly better performances in the open-skill group, demonstrating that regularly participating in such an exercise mode, as compared to the closed-skill one, could have more beneficial effects on visuospatial attention.     

Head and Trunk Control While Walking in Older Adults with Diabetes: Effects of Balance Confidence

Investigations of gait in older adults with diabetes mellitus (DM) have been primarily focused on lower limb biomechanical parameters. Yet, the upper body accounts for two thirds of the body's mass, and head and trunk control are critical for balance. The authors examined head and trunk control during self-selected comfortable, fast, and dual-task walking and the relationship between balance confidence and potential head-trunk stiffening strategies in older adults with DM without diagnosed diabetic peripheral neuropathy (DPN). Twelve older adults with DM without diagnosed DPN (DM group) and 12 without DM (no-DM group) were recruited. Walking speed, peak-to-peak head and trunk roll displacement, head and trunk roll velocity, and head-trunk correlation were measured while walking at a self-selected comfortable or fastest possible speed with or without a secondary cognitive task. The Activities-specific Balance Confidence scale measured balance confidence. Subtle group differences in axial segmental control (lower trunk roll velocity; higher head-trunk correlation) were apparent in older adults with DM even in the absence of DPN. Balance confidence was 19% lower in the DM group than in the no-DM group, and partially explained (34%) the group difference in head-trunk stiffening. These results emphasize the need for proactive monitoring of postural control and balance confidence before the onset of DPN.     

The generation and maintenance of visual mental images: evidence from image type and aging

Imagery is a multi-componential process involving different mental operations. This paper addresses whether separate processes underlie the generation, maintenance and transformation of mental images or whether these cognitive processes rely on the same mental functions. We also examine the influence of age on these mental operations for independence of components. In Experiment 1, younger (22 years) and older (69 years) adults generated and maintained general, specific, contextual and autobiographical visual mental images evoked in response to concrete nouns. The older adults had longer generation times, but there was no difference between the two groups on maintenance. Both groups had shortest generation and maintenance times for general images, whereas only the older adults took longest in generating autobiographical images. In Experiment 2, the total maintenance time and number of transformations for each type of image were compared in another group of younger and older adults. General images were less transformed and more subject to decay for both groups. The older people maintained the autobiographical mental images for longest compared to other image types. In conclusion, image generation, maintenance and transformation seem to be differently affected by type of image and aging, supporting a model of their cognitive segregation.     

Psychological type and counselling psychology trainees’ choice of counselling orientation

Clarifying the factors which influence choice of counselling orientation is important. This study investigated whether psychological type is associated with choice of orientation in counselling psychology trainees. Sets of questionnaires were sent to 210 counselling psychology trainees in four universities, which resulted in a sample of 84 participants. The measures were the Keirsey Temperament Sorter II and a short demographic questionnaire which also asked open-ended questions about chosen orientation. Participants who preferred SJ (Sensing-Judging) were more likely to choose the CBT model, NFJ (Intuition-Feeling-Judging) types the Psychodynamic model and NFPs (Intuition-Feeling-Perceiving) the Person-Centred model.
