教学心理学情感维度上的一种教材处理策略——心理匹配

在教学心理学领域中,人们往往习惯于从认知维度探索教材的优化处理策略,缺乏情感维度上的相应研究。奥苏贝尔虽提出意义学习的两个内在先决条件：一是学习者有同化新材料的认知结构;二是学习者有意义学习的心向．但他本人也仅从影响学生认知结构的角度,提出教材的认知处理策略──先行组织者策略．而未从影响学生心向的角度．提出教材的情感处理策略。鉴此,本文从情感维度上提出教材处理的心理匹配策略．以冀与认知策略一起共同优化处理教材、呈现教学内容环节,并阐明心理匹配策略的内涵、机制、作用和种类。     

Temporal factors influencing the pigeon's successive matching-to-sample performance: sample duration, intertrial interval, and retention interval

A successive matching-to-sample procedure that entails the sequential presentation of sample and test stimuli and the monitoring of response rates in a go/no-go discrimination of matching and nonmatching stimuli was studied as an alternative to the familiar delayed-matching paradigm of animal short-term memory. Three within-subject experiments studied the effects of sample duration (1 to 12 seconds), intertrial interval (5 to 50 seconds), and retention interval (1 to 50 seconds) on the pigeon's successive-matching performance. The results revealed that retention was (a) an increasing function of sample duration and intertrial interval, and (b) a decreasing function of retention interval. These results were in accord with those of more traditional short-term memory paradigms, and reveal the suitability of the successive-matching procedure for studying memory processes.     

通道呈现方式与感知学习风格的匹配性对粤-普双言切换代价的影响

选取不同感知学习风格的熟练粤-普双言者被试, 比较在不同通道呈现方式下他们刺激命名任务的表现, 由此考察感知学习风格与通道呈现方式的匹配性对熟练双言者双言切换代价的影响。结果发现, 被试在视觉线索呈现条件下要比在听觉线索条件下的切换代价小; 当感知学习风格与通道呈现方式匹配时, 双言切换代价更低。表明感知学习风格与通道呈现方式的匹配性对于双言切换代价有调节作用。     

Development and validation of the coach's task presentation scale: A quantitative self-report instrument

ObjectiveA major concern for coaches is the transmission of effective information in the moments before sport practice, when they communicate to players what they are supposed to do and how (Rink, 1994). The present study's main objective was to cover a gap in the sport psychology measurement field and to develop and validate a quantitative self-report instrument to measure the effectiveness of coaches' task presentation for athletes. The resulting instrument was the Escala de Presentación de las Tareas por Parte del Entrenador (EPTE) [Coach's Task Presentation Scale].DesignThe two studies developed to validate the EPTE used a cross-sectional research design.MethodParticipants in Study 1 included 830 college athletes aged between 18 and 27, who completed the EPTE. Participants in Study 2 included 677 college athletes aged between 17 and 29, who completed the EPTE and other questionnaires measuring coach's interpersonal style (autonomy support and controlling style) and basic psychological needs satisfaction/thwarting. Study 1 comprised translation, item formulation and examination of the reliability and factorial structure of the EPTE. Study 2 provided evidence of factorial validity and evidence of validity based on relationships with other variables in the context of the Self Determination Theory (Deci & Ryan, 2000).ResultsThe results of reliability analysis and the different sources of validity provided, demonstrated the instrument's adequacy in terms of psychometric properties.ConclusionsThe EPTE is a valid, reliable scale that can be used to measure the effectiveness of task presentation by coaches, according to the perception of athletes.     

数目和呈现方式对时距估计的影响

采用口头估计的方法,考察刺激的数目和呈现方式对时距估计的影响。以时距估计的平均值、准确性和变异性为指标,结果表明：（1）数目多少影响时距估计的平均值和准确性,数目少引起低估,数目多导致高估,数目多少与时距长度一致时,准确性高。（2）呈现方式影响时距估计的变异性,同时呈现时变异性最大;（3）数目和呈现方式的交互作用显著,固定频率和变化频率呈现时,数目影响时距估计。（4）随着时距的增加,时距估计的平均值由高估向低估,准确性由低向高发展。这表明时距和数目在心理表征上存在连接,数目和呈现方式在不同的时间范围内影响     

Inducing lucid dreams by olfactory-cued reactivation of reality testing during early-morning sleep: A proof of concept

The reliable induction of lucid dreams is a challenge in lucid dream research. In a previous study by our research group we were able to induce in about 50% of the participants a lucid dream in a single sleep laboratory night by combining a wake-up-back-to-bed sleep protocol and a mnemonic technique. In the present study, we extended our previous procedure by additional presentation of an odor during sleep to reactivate memory traces about reality testing. In total 16 male participants spent a single night in the sleep lab whereas the procedure induced in two participants a lucid dream (12.5%). The induction rate stays below the success rate of our previous study and therefore odor-cueing seems not a promising technique for inducing lucid dreams. Beside the odor presentation, several other methodological changes have been made, which will be discussed and hopefully help further dream engineering to improve induction techniques.     

Effect of task presentation on students’ performances in introductory statistics courses

Research on academic learning indicates that many students experience major difficulties with introductory statistics and methodology courses. We hypothesized that students’ difficulties may depend in part on the fact that statistics tasks are commonly viewed as related to the threatening domain of math. In two field experiments which we carried out in the ecological context of introductory statistics courses, the representation of a statistics task administered to undergraduate students in Psychology (Study 1; n = 127) and Biology (Study 2; n = 166) was manipulated. In both studies we found that students who reported the least favorable prior attainments in math had their performance thwarted when the task was presented as related to the math domain, whereas no performance impairment was observed when the task was presented as related to the verbal/linguistic domain. Implications of the findings for the design and delivery of introductory statistics and research methodology courses are discussed.

呈现方式与认知方式对文章标记效应的影响

采用纸笔呈现和视频显示终端(video display terminab,VDT)呈现两种形式,探讨了认知方式与文章标记类型对文章阅读效果的影响,结果表明: (1)文章标记对不同认知方式的读者影响不同,无论有无文章标记,场独立者对各类信息的保持量没有明显的变化,而文章的宏观标记能够使场依存者的阅读指向发生改变,场依存者会更加注意与标记有关的内容; (2)呈现方式对文章信息的保持量有显著的影响,纸笔呈现方式下,被试的信息保持量明显好于VDT呈现方式; (3)在VDT呈现条件下,场独立者对主题性信息的保持量显著高于场依存者.     

Spontaneous number representation in mosquitofish

While there is convincing evidence that preverbal human infants and non-human primates can spontaneously represent number, considerable debate surrounds the possibility that such capacity is also present in other animals. Fish show a remarkable ability to discriminate between different numbers of social companions. Previous work has demonstrated that in fish the same set of signature limits that characterize non-verbal numerical systems in primates is present but yet to provide any demonstration that fish can really represent number rather than basing their discrimination on continuous attributes that co-vary with number. In the present work, using the method of ‘item by item’ presentation, we provide the first evidence that fish are capable of selecting the larger group of social companions relying exclusively on numerical information. In our tests subjects could choose between one large and one small group of companions when permitted to see only one fish at a time. Fish were successful when both small (3 vs. 2) and large numbers (8 vs. 4) were involved and their performance was not affected by the density of the fish or by the overall space occupied by the group.
