Aftereffects for face attributes with different natural variability: Children are more adaptable than adolescents

Adults can be adapted to a particular facial distortion in which both eyes are shifted symmetrically (Robbins, R., McKone, E., & Edwards, M. (2007). Aftereffects for face attributes with different natural variability: Adapter position effects and neural models. Journal of Experimental Psychology: Human Perception and Performance, 33, 570–592), but they do not show as great adaptation to an asymmetrical eye distortion. We adapted children and adolescents to symmetrical and asymmetrical eye distortions and measured the aftereffects. Children (aged 6–12, mean age 9 years) showed larger aftereffects than adolescents (aged 13–18, mean age 15 years) and demonstrated aftereffects of a similar magnitude for both asymmetrical and symmetrical distortions. Adolescents only showed aftereffects for symmetrical distortions. We propose that children may have a more flexible face norm and neural responses that allow a broader range of adapted states compared to adolescents.     

人格特质与主观幸福感:情绪调节的中介作用

通过对1163名大学生被试进行人格特质、情绪调节策略的使用以及主观幸福感的测查,本研究探讨了气质性人格特质(神经质和外倾性)这种稳定的内在心理结构对主观幸福感产生影响的可能机制。结果发现:(1)除直接影响个体的主观幸福感外,神经质和外倾性还会通过重新评价策略的使用间接影响主观幸福感;(2)人格特质和重新评价策略的使用可以有效预测个体主观幸福感的变异;(3)习惯性地使用表达抑制策略对个体的主观幸福感并没有显著的影响。这些结果表明重新评价策略的使用在人格特质对主观幸福感的影响中具有重要的中介作用。该发现对进一步制定改善和提高个体的主观幸福感的干预措施具有重要的启示和指导意义。     

Processing time predictions of current models of perception in the classic additive factors paradigm

This article explores the consequences for factorial additivity in a Sternberg [(1969). The discovery of processing stages: Extensions of donders method In: W.G. Koster (Ed.), Attention and performance II, Acta Psychologica, 30, 276-315] additive-factors paradigm of the assumptions adopted by models of perception that relate the representation of a stimulus to decision time. Three example models, signal detection theory with the latency-distance hypothesis, stochastic general recognition theory, and a random walk model of exemplar classification, are interrogated to determine what type of interaction they predict factors will yield in a hypothetical factorial (choice) reaction time experiment in which the ‘empirical’ factors’ effects are manifest as parameter changes. All frameworks make the critical assumption that decision time depends on the perceptual representation of the stimulus as well as the architecture. As a consequence, nonadditivity of factors thought to affect different “stages” in the classical approach emerges within the current modeling approach. The nature of this influence is revealed through analytic investigations and simulation. Earlier empirical findings of failures of selective influence that have defied adequate explanation are reinterpreted in light of the present findings.     

“Kiss Your Period Good-Bye”: Menstrual Suppression in the Popular Press

The purpose of this study was to analyze the content of popular press articles about menstrual suppression, a relatively new and controversial health care option. Twenty-two American and Canadian articles, published before the FDA approval of Seasonale, were coded for basic information about and indications for menstrual suppression, viewpoints included, and coverage of risks and benefits. Menstrual suppression was most often recommended for women with menstrual disorders but was also recommended to menstruating women in general as a matter of convenience. Advocates of menstrual suppression were quoted twice as often as opponents. Monthly menstruation was frequently described as messy, inconvenient, bothersome, unhealthy, and unnecessary. From this analysis, we concluded that popular press coverage of menstrual suppression is insufficient and biased. The articles reflect and reinforce the taboo status and medicalization of menstruation. This coverage may have primed potential consumers to anticipate the FDA approval of Seasonale eagerly, to evaluate it uncritically, and to pursue it as a birth control and menstrual health option. Implications for research, health care providers, and menstrual activists are discussed.An earlier version of this paper was presented at the June 2003 meeting of the Society for Menstrual Cycle Research, Pittsburgh, PA.     

Unconscious arithmetic: Assessing the robustness of the results reported by Karpinski,Briggs, and Yale (2018)

In 2012, a study by Sklar et al. reported that participants could solve invisible subtractions. This notion of unconscious arithmetic has been influential because it challenges current theories of consciousness. In 2016, Karpinski et al. published a direct replication reporting evidence for unconscious addition rather than subtraction. About a year later, the study was retracted due to a computation error in the analysis pipeline. After this error was corrected, no evidence for unconscious addition nor subtraction was obtained. Recently, Karpinski et al. republished the study by applying the exclusion criteria used in Sklar et al. The reanalysis found weak evidence for unconscious subtraction. To assess the robustness of these results, we examine how sensitive the results are to data analytic decisions. We outline a set of 250 analyses that we consider justified to perform. We show that none of the analyses indicates evidence for unconscious subtraction.     

Perceived emotion suppression and culture: Effects on psychological well‐being

Whether the negative effects of emotion suppression on psychological well‐being are applicable cross‐culturally is a long‐debated topic. The present study attempted to shed light on this debate, focusing on the effects of perceived emotion suppression and examining the psychological processes leading from perceived emotion suppression to lower psychological well‐being. We used a scale manipulation to lead 196 American and 213 Chinese participants to perceive themselves as having suppressed their emotions to a greater or lesser extent and then measured their life satisfaction. As expected, both the American and Chinese participants reported lower life satisfaction in the high‐suppression condition than in the low‐suppression condition; this negative effect was mediated by positive affect and moderated by self‐esteem. Specifically, perceived high emotion suppression decreased positive affect, which in turn led to lower well‐being. This effect was observed only for those with low self‐esteem, but the patterns and mechanisms were consistent cross‐culturally.     

Early top-down influences on bistable perception revealed by event-related potentials

A longstanding debate exists in the literature concerning bottom-up vs. top-down influences on bistable perception. Recently, a technique has been developed to measure early changes in brain activity (via ERPs) related to perceptual reversals (Kornmeier & Bach, 2004). An ERP component, the reversal negativity (RN) has been identified, and is characterized as an increase in negative potential over the posterior scalp from 150 to 350 ms for perceptual reversals compared to perceptual stability. This finding, although interesting, has not helped resolve issues related to the bottom-up vs. top-down debate because top-down influences have not been directly manipulated. The current study focused on resolving some of these issues by measuring the RN while observers maintained one of three 'intentional approaches', (1) try to reverse perception as often as possible, (2) try to stabilize perception for as long as possible, and (3) maintain a passive approach. Enhancements in RN amplitude were found for the intention-to-reverse condition compared to the passive condition. This finding suggests an early influence (150 ms) of top-down control on perceptual reversals of bistable figures. Results are discussed in terms of competing attention shifting vs. fatigue-based theories of bistable perception.     

不同类型的知觉刺激对语言理解的影响

采用知觉负载范式探讨知觉刺激对语言理解的影响。实验1考察被试在加工听觉概念和视觉概念时的表征形式。实验2进一步探讨在同一通道内部,形状概念和视觉概念的表征形式。实验1发现,在进行语言理解时,如果存在听知觉负荷,加工语言中的听觉信息时会变慢。如果存在视知觉负荷,加工语言中的视觉信息时错误率会增加。实验2发现,在涉及视觉信息的语言理解中,颜色知觉负荷产生了广泛的影响,而形状知觉负荷没有表现出这种效应。总的实验结果表明,不同类型的知觉刺激对语言理解产生了不同的影响。语言理解中存在着模态化和非模态化两种不同的加工模式。     

熟练和非熟练中英双语者不同认知控制成分的比较

使用面孔任务考察熟练中英双语者和非熟练中英双语者在不同认知控制成分上的差异。被试为60名大学生。结果表明,熟练中英双语者在抑制控制和转换上的反应时消耗量均显著小于非熟练中英双语者,但在反应抑制上的反应时消耗量与非熟练中英双语者没有显著差异。该结果说明,二语熟练程度越高,中英双语者的认知灵活性(转换)和抑制控制(干扰控制)能力就越强;但是二语熟练程度对反应抑制能力没有明显的影响。由此可以推测,二语学习能促进中英双语者的认知灵活性(转换)和抑制控制(干扰控制)能力,但是,二语学习对中英双语者的反应抑制能力没有明显的促进作用。     

The role of thought suppression in building mental blocks

This research examined the role of thought suppression in the formation of mental blocks. In Experiment 1, participants were asked to generate a series of creative associates for two target words after initially suppressing a word that was semantically related to one of the two target words. Participants produced fewer responses, and experienced a greater sensation of being mentally blocked, when attempting to produce associates for the target word that was semantically related to the suppressed word. In Experiment 2, participants either thought about or suppressed a series of words prior to completing a word fragment completion task. Each word either corresponded exactly to one of the word fragment solutions (target primes) or resembled one of the solutions but was slightly different in its orthographic properties (negative primes). Participants performed most poorly on the items for which they had initially suppressed negative primes.
