The purpose of the study was to explore the ways in which young South African children construct the notion of happiness. The small-scale study was conducted with children (n=42) in middle childhood between the ages of 6 and 13 years. Four fieldworkers were trained to elicit responses from young children through face-to-face, semi-structured interviews and six open-ended questions. This data collection strategy was twinned with the elicitation of graphic representations of ‘happiness’ as expressed and projected by the young children. Observations and audiotape data capturing served as secondary data sources. Interviews were transcribed verbatim and analysed through theme analysis. Axial coding followed open coding as themes emerged. Graphic representations were analysed using basic psychological analysis techniques and then correlated with established themes from the interview data. Results from the study indicate that the participants in the study constructed ‘happiness’ predominantly in terms of relationships, recreation and the attainment of material possessions. 相似文献

We developed masked visual analysis (MVA) as a structured complement to traditional visual analysis. The purpose of the present investigation was to compare the effects of computer‐simulated MVA of a four‐case multiple‐baseline (MB) design in which the phase lengths are determined by an ongoing visual analysis (i.e., response‐guided) versus those in which the phase lengths are established a priori (i.e., fixed criteria). We observed an acceptably low probability (less than .05) of false detection of treatment effects. The probability of correctly detecting a true effect frequently exceeded .80 and was higher when: (a) the masked visual analyst extended phases based on an ongoing visual analysis, (b) the effects were larger, (c) the effects were more immediate and abrupt, and (d) the effects of random and extraneous error factors were simpler. Our findings indicate that MVA is a valuable combined methodological and data‐analysis tool for single‐case intervention researchers. 相似文献

汉字识别中形音义激活时间进程的研究(Ⅰ) 总被引:6,自引:1,他引:5
分别采用基于语义的和基于语音的启动范畴判断作业,在不同的SOA条件下,考察高频汉字识别中形音义信息激活的相对时间进程。两个实验的结果表明,高频汉字形音义激活的时序为字形—字义—字音的顺序。这一结果揭示,高频汉字字义的提取更符合直通理论的预期。高频汉字的语音是自动激活的,但语音的激活可能发生在字义通达之后。 相似文献

Although considerable attention has been given to the development of institutional staff training and management programs, the generalized effects of such programs on staff and resident behavior have seldom been examined. This study evaluated a program for teaching institutional staff behavioral training and self-management skills during self-care teaching sessions with severely and profoundly retarded residents. Following baseline observations in three self-care situations (toothbrushing, haircombing, handwashing), four direct care staff were sequentially taught to use verbal instruction, physical guidance, and contingent reinforcement in the toothbrushing program. During maintenance, staff were simultaneously taught to record, graph, and evaluate resident and their own behavior in the toothbrushing sessions. Staff were taught use of the training and self-management skills through a sequence of written instructions, videotaped and live modeling, rehearsal, and videotaped feedback. Observer presence and experimenter supervision were gradually decreased during the maintenance condition. Results indicated that during training and maintenance staff: (a) learned to use the training skills appropriately and consistently in the example situation (toothbrushing); (b) applied the skills in the generalization situations (haircombing and handwashing); and thereafter (c) maintained consistent and appropriate use of the skills with infrequent supervision. In addition, important changes in retarded residents' independent self-care responding occurred as staff training skills developed. Results are discussed in terms of their implication for future research and continued development of effective staff training and management programs. 相似文献

We examined customer greeting by employees at one location of a sandwich restaurant chain. First, a preintervention analysis was conducted to determine the conditions under which greeting a customer within 3 s of his or her entry into the restaurant did and did not occur. Results suggested that an appropriate customer greeting was most likely to occur when a door chime was used to indicate that a customer had entered the store and when the store manager was present behind the service counter. Next, a performance improvement intervention, which consisted of the combination of the use of a door chime and manager presence, was evaluated. Results showed that during baseline, a mean of 6% of customers were greeted; during intervention a mean of 63% of customers were greeted. The addition of manager-delivered verbal and graphic group feedback resulted in 100% of customers being greeted across two consecutive sessions. 相似文献

基于单探测变化觉察和双任务范式,采用项目数量(3)×呈现时间(2)×文字线索(2)混合实验设计,对沉浸式虚拟学习环境图形加工特征和认知负荷进行探讨,以任务绩效法与主观测量法评定认知负荷。44名大学生的实验结果显示:(1)项目数量对虚拟空间图形识记主任务绩效和主观认知负荷有显著影响,项目数量越多,主任务正确率越低,反应时越长,主观评定认知负荷越高,同时加工刺激数量以4个为宜;(2)呈现时间对虚拟空间图形识记次任务绩效有显著影响,呈现时间越长,次任务正确率越高,呈现时间超过0.5s有利于次任务加工;(3)文字线索对虚拟图形识记认知负荷有显著影响,重复性文字线索会增加认知负荷。结果表明,在沉浸式虚拟环境中,图形加工的认知负荷特点与平面和三维图形基本一致,项目数量多、呈现时间短以及有重复性文字线索时,认知负荷更高;任务绩效和主观测量评定指标在反映认知负荷强度上不完全一致。 相似文献
