Testing two variances for superiority/non-inferiority and equivalence: Using the exhaustion algorithm for sample size allocation with cost

The equality of two group variances is frequently tested in experiments. However, criticisms of null hypothesis statistical testing on means have recently arisen and there is interest in other types of statistical tests of hypotheses, such as superiority/non-inferiority and equivalence. Although these tests have become more common in psychology and social sciences, the corresponding sample size estimation for these tests is rarely discussed, especially when the sampling unit costs are unequal or group sizes are unequal for two groups. Thus, for finding optimal sample size, the present study derived an initial allocation by approximating the percentiles of an F distribution with the percentiles of the standard normal distribution and used the exhaustion algorithm to select the best combination of group sizes, thereby ensuring the resulting power reaches the designated level and is maximal with a minimal total cost. In this manner, optimization of sample size planning is achieved. The proposed sample size determination has a wide range of applications and is efficient in terms of Type I errors and statistical power in simulations. Finally, an illustrative example from a report by the Health Survey for England, 1995–1997, is presented using hypertension data. For ease of application, four R Shiny apps are provided and benchmarks for setting equivalence margins are suggested.     

The Relationship between Emotional Intelligence and Domain-Specific and Domain-General Creativity

The Amusement Park Theory of Creativity, which represents both domain-specific and domain-general perspectives of creativity, calls for more research on how individual difference constructs are related to creativity at all ends of the domain-specificity and general spectrum. Toward this goal, this study examined emotional intelligence (using the Emotional Intelligence Scale) in relationship with both a domain-general measure (the Abbreviated Torrance Test for Adults) and a domain-specific measure (Kaufman Domains of Creativity Scale) in a sample of 281 Chinese undergraduates. Although emotional intelligence demonstrated no relationship with divergent thinking, it did positively predict all five domains of creativity on the self-report measure (ranging from .52 to .77). These findings add to the nuanced relationship between emotional intelligence and creativity and serve as a call for more work of this nature.     

未意识到错误影响错误后调整的电生理证据

现有研究一致认为意识到错误可引起错误后调整, 但是未意识到错误能否促使个体进行错误后调整尚存争议。本实验采用基于go/no-go范式的错误意识任务考察上述问题, 并根据被试对自己按键反应正误主观报告将no-go错误反应分为意识到错误和未意识到错误。行为结果发现, 意识到错误和未意识到错误后正确率均显著高于正确击中试次(正确go试次)后正确率; 但是, 意识到错误后试次反应时显著快于正确击中后反应时, 未意识到错误后反应时显著慢于正确击中后反应时。该结果表明两类错误均优化了错误后行为表现, 但是意识到错误后被试调整速度加快, 未意识到错误后被试调整速度减慢。进而, 时频分析发现意识到错误相较于未意识到错误诱发显著更强的alpha波能量。并且, 前者在错误意识主观报告前已诱发alpha波, 后者在错误意识主观报告反应后诱发alpha波。该结果表明意识到错误一直处于持续的注意监控中, 而未意识到错误是任务引起的暂时注意控制。因此, 本实验说明错误意识影响错误后调整, 意识到错误可能采用类似主动性控制的策略调节错误后行为, 而未意识到错误可能采用类似反应性控制的策略调节错误后行为。     

语言转向和西方心理学理论和研究的深入发展

语言转向是西方哲学自我批判的产物,对西方心理学摆脱“康德式难题”具有重要意义。该文以西方哲学语言转向的内在逻辑为理论背景,分析了由此引发的西方心理学研究主题、线索和路径变迁。分析哲学、解释学和结构主义是语言转向的三种方式,共同实现了20世纪的语言转向,影响心理学理论和研究的变迁,推动心理学关注语言建构和文本陈述,激发新的心理学理论和研究。     

低阶层大学生的炫耀性消费:自尊补偿与地位追求

近年来低阶层大学生炫耀性消费负性事件频发,研究以补偿性消费理论为基础,考察低阶层大学生炫耀性消费的内因与外因。实验一通过比较高、低状态自尊条件下不同阶层被试的炫耀性消费倾向来考察自尊的作用,结果表明低阶层大学生的炫耀性消费倾向受到其状态自尊的调节; 实验二通过比较不同阶层被试对地位及非地位符号商品的支付意愿来考察商品符号价值的作用,结果表明低阶层大学生只有在商品具有地位符号价值时,才会表现出比高阶层大学生更强烈的炫耀性消费倾向。     

叠音品牌名称对消费者知觉和态度的影响

品牌名称是重要的品牌资产, 在传递品牌价值、构建品牌形象和凸显品牌特征的过程中起到关键作用。以往研究发现, 品牌名称的语义特征和语音特征(元音、辅音)都会对消费者知觉和态度产生影响, 但少有研究考察叠音这种语音结构特征的作用。从婴儿图式的角度, 考察叠音品牌名称对消费者知觉和态度的影响, 并检验其作用机制和边界。具体内容包括：(1)考察叠音品牌名称对消费者品牌知觉(物理特征知觉、心理特征知觉)及其消费者态度的影响及其作用机制。(2)检验内部语音特征和外部线索特征在叠音品牌名称与消费者知觉之间的调节作用。(3)检验产品类型特征和消费者特征在叠音品牌名称和消费者态度之间的调节作用。     

Velocity dependence of the interocular transfer of dynamic motion aftereffects

It is well established that motion aftereffects (MAEs) can show interocular transfer (IOT); that is, motion adaptation in one eye can give a MAE in the other eye. Different quantification methods and different test stimuli have been shown to give different IOT magnitudes, varying from no to almost full IOT. In this study, we examine to what extent IOT of the dynamic MAE (dMAE), that is the MAE seen with a dynamic noise test pattern, varies with velocity of the adaptation stimulus. We measured strength of dMAE by a nulling method. The aftereffect induced by adaptation to a moving random-pixel array was compensated (nulled), during a brief dynamic test period, by the same kind of motion stimulus of variable luminance signal-to-noise ratio (LSNR). The LSNR nulling value was determined in a Quest-staircase procedure. We found that velocity has a strong effect on the magnitude of IOT for the dMAE. For increasing speeds from 1.5 deg s(-1) to 24 deg s(-1) average IOT values increased about linearly from 18% to 63% or from 32% to 83%, depending on IOT definition. The finding that dMAEs transfer to an increasing extent as speed increases, suggests that binocular cells play a more dominant role at higher speeds.
