Marginally perceptible outcome feedback, motor learning and implicit processes

Participants struck 500 golf balls to a concealed target. Outcome feedback was presented at the subjective or objective threshold of awareness of each participant or at a supraliminal threshold. Participants who received fully perceptible (supraliminal) feedback learned to strike the ball onto the target, as did participants who received feedback that was only marginally perceptible (subjective threshold). Participants who received feedback that was not perceptible (objective threshold) showed no learning. Upon transfer to a condition in which the target was unconcealed, performance increased in both the subjective and the objective threshold condition, but decreased in the supraliminal condition. In all three conditions, participants reported minimal declarative knowledge of their movements, suggesting that deliberate hypothesis testing about how best to move in order to perform the motor task successfully was disrupted by the impoverished disposition of the visual outcome feedback. It was concluded that sub-optimally perceptible visual feedback evokes implicit processes.     

When 9 is not on the right: Implications from number-form synesthesia

Number-form synesthetes consciously experience numbers in spatially-defined locations. For non-synesthete individuals, a similar association of numbers and space appears in the form of an implicit mental number line as signified by the distance effect–reaction time decreases as the numerical distance between compared numbers increases. In the current experiment, three number-form synesthetes and two different non-synesthete control groups (Hebrew speaking and English speaking) performed a number comparison task. Synesthete participants exhibited a sizeable distance effect only when presented numbers were congruent with their number-form. In contrast, the controls exhibited a distance effect regardless of congruency or presentation type. The findings suggest that: (a) number-form synesthesia impairs the ability to represent numbers in a flexible manner according to task demands; (b) number-form synesthesia is a genuine tangible experience, triggered involuntarily; and (c) the classic mental number line can be more pliable than previously thought and appears to be independent of cultural-lingo direction.     

Beyond perception: Testing for implicit conceptual traces in high-load tasks

The present commentary addresses the main results obtained in the Butler and Klein [Butler, B. C., & Klein, R. (2009). Inattentional blindness for ignored words: Comparison of explicit and implicit memory tasks. Consciousness and Cognition, 18, 811–819.] study and discusses them in relation to the Perceptual Load Theory of Lavie [Lavie, N. (1995). Perceptual load as a necessary condition for selective attention. Journal of Experimental Psychology: Human Perception and Performance, 21, 451–68.]. The authors claim that the use of implicit indexes of conceptual distractor processing in high-load situations would be an important addition to the load literature, which would benefit the research field regardless of their positive or negative findings.     

Dual effects of implicit bystanders: Inhibiting vs. facilitating helping behavior

Encouraging consumers to engage in helpful behavior is a perennial task of marketers in non-profit and for-profit organizations. Recent research suggests that merely imagining the presence of others can lead to less helping behavior on a subsequent unrelated task (Garcia, S.M., Weaver, K.D., Moskowitz, G.B., and Darley, J.M. (2002). Crowded minds: The implicit bystander effect. Journal of Personality and Social Psychology, 83, 843–853.). The present analysis uncovers the boundary conditions of this effect. Across four studies, we establish that the degree to which a group situation fosters public scrutiny is an important moderator. When group primes are paired with public scrutiny, their inhibitive effect on helping behavior diminishes, and helping behavior on a subsequent task tends to increase. The present research thus adds complexity to previous findings by suggesting that implicit bystanders can both decrease and increase helping behavior.     

内隐自尊效应及内隐自尊与外显自尊的关系

研究运用内隐联想测验对内隐自尊进行了研究和测量,同时还运用结构方程建模对外显自尊和内隐自尊的结构关系进行了研究,结果表明：(1)东方文化下内隐自尊是存在的,个体无意识中对自我持有一种积极的评价,但强度不如西方个体。(2)内隐自尊与外显自尊是相对独立的两个不同的结构,二者间仅存在低的正相关。     

性别-学科刻板印象的加工模式实验研究

性别刻板印象是在继种族刻板印象之后,逐渐受到研究者们关注的热点问题。本文运用内隐联想测量法来探讨大学生性别一学科刻板印象的加工模式,采用3×2×2的三因素完全随机设计进行实验研究。结果表明：内隐和外显的性别-学科刻板印象出现了实验分离现象。三个不同的内隐测量组的被试均不同程度认为男女性在学习文科时能力相当,学习理科方面则男性明显优于女性。但在外显测试中被试们却认为两者在学习文理科时无差异。结论：内隐性别一学科刻板印象更倾向于一种自动化加工,采用的是“自上而下”的省时省力加工模式。而外显性别一学科刻板印象趋向于自动加工与控制加工相结合,是一种“自下而上”、“三思而答”的加工模式。     

An impossibility theorem for verisimilitude

In this paper, we show that Arrow’s well-known impossibility theorem is instrumental in bringing the ongoing discussion about verisimilitude to a more general level of abstraction. After some preparatory technical steps, we show that Arrow’s requirements for voting procedures in social choice are also natural desiderata for a general verisimilitude definition that places content and likeness considerations on the same footing. Our main result states that no qualitative unifying procedure of a functional form can simultaneously satisfy the requirements of Unanimity, Independence of irrelevant alternatives and Non-dictatorship at the level of sentence variables. By giving a formal account of the incompatibility of the considerations of content and likeness, our impossibility result makes it possible to systematize the discussion about verisimilitude, and to understand it in more general terms.     

Implicit Motives Modulate Attentional Orienting to Facial Expressions of Emotion

We conducted two studies (Ns=52 and 60) to test the notion that the incentive salience of facial expressions of emotion (FEE) is a joint function of perceivers’ implicit needs for power and affiliation and the FEE’s meaning as a dominance or affiliation signal. We used a variant of the dot-probe task (Mogg & Bradley, 1999a) to measure attentional orienting. Joy, anger, surprise, and neutral FEEs were presented for 12, 116, and 231 ms with backward masking. Implicit motives were assessed with a Picture Story Exercise. We found that power-motivated individuals orient their attention towards faces signaling low dominance, but away from faces that signal high dominance, and (b) that affiliation-motivated individuals show vigilance for faces signaling low affiliation (rejection) and, to a lesser extent, orient attention towards faces signaling high affiliation (acceptance).     

Recognition failure of recallable words: problems of mathematical constraint and dependence

The graph space of P ( RN | RL ) vs. P ( RN ), probabilities of recognition given recall and overall recognition, is the setting for the Tulving-Wiseman (TW) function of recognition failure research. According to Hintzman (1991, 1992), the moderate scatter of data points about the TW curve is an artefactual regularity caused by a mathematical constraint when P ( RN ) < P ( RL ). However, both constrained and unconstrained (when P ( RN ) ≥ P ( RL )) points conform equally well to the TW function, consistent with the unobserved fact that the location of both kinds of points is determined by the same mathematical rule. Hintzman's claim that there is no regularity in the data plot when P ( RN ) < P ( RL ) other than that produced by the constraint is not supported by this study. He based his claim on an incorrect use of the measure of dependence (association) called gamma. The graph space corresponding to gamma is that of P ( RN | RL ) vs. P ( RN | nRL ), as shown by using the Bayes function (Bayes' theorem). The margin-free measure gamma is a function of two thetas, theta being a margin-sensitive measure of dependence that is the parameter of the Bayes function. The variance of gamma reflects the fact that it is compounded of the theta variances, so a margin-free measure is obtained at the expense of greater variability.     

影响被告人供述的因素及其对策的研究

以１９５名执法人员和１８５名服刑犯人为被试,采用问卷法研究了影响被告人供述的因素以及相应的对策建议。结果表明：（１）有１０种因素被认为对被告人未能形成供述动机有影响作用,有９种因素被认为对被告人形成如实供述动机有影响作用,其中,执法人员所认为的影响作用基本上都比服刑犯人所认为的要大,同时,双方具有各自的倾向性;（２）有１５种因素被认为对愿意供述的被告人未能如实供述可能存在影响作用,其中６种因素确实有一定的影响;（３）有９种对策被普遍认为对解决被告人不愿供述问题有效,有１０种对策被认为对解决愿意供述的被告人未能如实供述的问题有效,同时,执法人员和服刑犯人在关于对策有效性的评价上具有互补性。
