The role of auditory context in action-effect-related motor adaptation

Previous research indicates that adding auditory effects to a (silent) action can lead to substantial efficiency gains in the performance of the action, while compromising the connection between the motor and the auditory event (e.g., by removing, or by delaying the auditory effects), leads the agent to compensate for the loss of auditory feedback by executing actions in a way which increases the probability of success or enhances feedback in other modalities, thus departing from the optimal action performance. The current study explored how this motor adaptation was affected when the quality of auditory feedback was reduced by contextual factors, while keeping the physical link between the action and auditory effect intact. In two experiments, participants elicited pure tones by pinching a force sensitive resistor (FSR). In some of the conditions action-effect contingency was reduced by intermixing externally initiated tones with the self-induced ones. Pinch-force measurements indicated that action optimization was affected by contextual factors. The influence of auditory context was the most pronounced when the discrimination of self-induced and external tones was made difficult by the similarity and temporal proximity of the self-induced and external tones. In these conditions, tone eliciting actions were more forceful in comparison to conditions in which no external tones were presented, and in comparison to conditions in which the external tones were easily distinguishable from self-induced ones. This suggests that contextual factors can induce similar motor adjustments as manipulating the physical connection between the action and its sensory consequences.     

双任务并存条件下的信息提取

将短时记忆再认与长时记忆范畴判断两类不同性质的信息提取任务相并列,探讨了双任务条件下的信息提取过程是如何进行的。实验结果表明,双任务并存时,ｎｏ反应的总平均反应时不等于两种任务单独进行时各自ｎｏ反应的平均反应时之和（减去一次视觉动作反应时后）,而是与其中一个较后完成的过程的ｎｏ反应平均反应时相近。因此推断双任务并存时,信息提取过程不是完成一个再进行另一个的系列加工过程,而是二者同时平行加工的过程。

Time and direction preparation of the long latency stretch reflex

This study investigated time and direction preparation of motor response to force load while intending to maintain the finger at the initial neutral position. Force load extending or flexing the index finger was given while healthy humans intended to maintain the index finger at the initial neutral position. Electromyographic activity was recorded from the first dorsal interosseous muscle. A precue with or without advanced information regarding the direction of the forthcoming force load was given 1000 ms before force load. Trials without the precue were inserted between the precued trials. A long latency stretch reflex was elicited by force load regardless of its direction, indicating that the long latency stretch reflex is elicited not only by muscle stretch afferents, but also by direction-insensitive sensations. Time preparation of motor response to either direction of force load enhanced the long latency stretch reflex, indicating that time preparation is not mediated by afferent discharge of muscle stretch. Direction preparation enhanced the long latency stretch reflex and increased corticospinal excitability 0–20 ms after force load when force load was given in the direction stretching the muscle. These enhancements must be induced by preset of the afferent pathway mediating segmental stretch reflex.     

Affect,Desire, and Judgement in Spinoza's Account of Motivation

Two priority problems frustrate our understanding of Spinoza on desire [cupiditas]. The first problem concerns the relationship between desire and the other two primary affects, joy [laetitia] and sadness [tristitia]. Desire seems to be the oddball of this troika, not only because, contrary to the very definition of an affect (3d3; 3 General Definition of the Affects), desires do not themselves consist in changes in one's power of acting, but also because desire seems at once more and less basic than joy and sadness. The second problem concerns the priority of desires and evaluative judgements. While 3p9s and 3p39s suggest that evaluative judgements are (necessarily) posterior to desires, Andrew Youpa has recently argued that passages in Ethics 4 indicate that rational evaluative judgements can give rise to, rather than arise out of, desires. I aim to offer solutions to these problems that reveal the elegance and coherence of Spinoza's account of motivation. Ultimately, I argue that whereas emotions and desires stand in a non-reductive, symmetrical relationship to one another, evaluative judgements must be understood as asymmetrically dependent on, and reducible to, emotions or desires. This interpretation sheds light on our understanding of Spinoza's cognitivist account of emotion. For Spinoza, while emotions are representational, they are not underpinned by evaluative judgements. Rather than inflating emotions to include evaluative judgements, he deflates evaluative judgements, treating them as emotions, or valenced representations, and nothing more.     

Moral internalism,amoralist skepticism and the factivity effect

Philosophers are divided over moral internalism, the claim that moral judgement entails some motivation to comply with that judgement. Against moral internalism, externalists defend the conceptual coherence of scenarios in which an individual makes genuine moral judgements but is entirely unmoved by them. This is amoralist skepticism and these scenarios can be called amoralist scenarios. While the coherence of amoralist scenarios is disputed, philosophers seem to agree that the coherence of amoralist scenarios is not affected by whether the amoralist is described as having moral knowledge or mere belief. But recent experimental research challenges this assumption. When evaluating amoralist scenarios, people’s intuitions lean towards externalism when the amoralist is described as knowing that X is morally wrong, whereas people’s intuitions lean towards internalism when the amoralist is described as believing that X is morally wrong. Call this the factivity effect. In this paper, I argue that the factivity effect is unlikely to be explained as an experimental artifact and that as a consequence, the traditional dispute over moral internalism and amoralist skepticism may need a major overhaul. The results of three studies testing the factivity effect provide support for this thesis. Implications of these results for the traditional debate over moral internalism are discussed.     

SNARC (spatial–numerical association of response codes) meets SPARC (spatial–pitch association of response codes): Automaticity and interdependency in compatibility effects

Concepts, including the mental number line, or addressing pitch as high and low, suggest that the spatial–numerical and spatial–pitch association of response codes (SNARC and SPARC) effects are domain-specific and thus independent. Alternatively, there may be dependencies between these effects, because they share common automatic or controlled decision mechanisms. In two experiments, participants were presented with spoken numbers in different pitches; their numerical value, pitch, and response compatibility were varied systematically. This allowed us to study SNARC and SPARC effects in a factorial design (see also Fischer, Riello, Giordano, &; Rusconi, 2013 Fischer, M. H., Riello, M., Giordano, B. L., &; Rusconi, E. (2013). Singing numbers?…?in cognitive space--a dual-task study of the link between pitch, space, and numbers. Topics in Cognitive Science, 5(2), 354–366. Retrieved from http://doi.org/10.1111/tops.12017[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Participants judged the stimuli on numerical magnitude, pitch, or parity (odd–even). In all tasks, the SNARC and SPARC effects had superadditive interactions. These were interpreted as both effects sharing a common mechanism. The task variation probes the mechanism: In the magnitude judgement task, numerical magnitude was explicit, whereas pitch was implicit; in the pitch judgement task, it was vice versa. In the parity judgement task, both dimensions were implicit. Regardless of whether they were implicit or explicit, both SNARC and SPARC effects occurred in all tasks. We concluded that by not requiring focal attention the common mechanism operates automatically.     

Measurement scales and scale independence in the analytic hierarchy process

One approach to evaluate the relative performance of decision alternatives with respect to multiple criteria is provided by the analytic hierarchy process. The method is based on pairwise comparisons between attributes, and several numerical measurement scales for the ratio statements have been proposed. The choice of measurement scale is re‐examined, and new arguments supporting the measurement scale of geometric progression are derived. Separately from the measurement scale considerations, the effects of the scale parameter in geometric measurement scale are also studied. By using a regression model for pairwise comparisons data, it is shown that the statistical inference does not depend on the value of the scale parameter in the case of a single pairwise comparison matrix. It is also shown when the scale independence of statistical inference can be achieved in a decision hierarchy. This requires the use of the geometric‐mean aggregation rule instead of the traditional arithmetic‐mean aggregation. The results of the case study demonstrate that the measurement scale and the aggregation rule have potentially large impacts on decision support. Copyright © 2000 John Wiley & Sons, Ltd.     

Judging Yourself as You Judge Others: Moral Development and Exculpation

This study investigated two main issues: Whether people's judgments about real-life moral transgressions are affected by the role they play in them and whether self-serving biases in such judgments vary with level of moral development. One-hundred twenty university students took Colby and Kohlberg's (1987) test of moral judgment and made open-ended and rating-scale judgments about three real-life transgressions they considered moral in nature. As expected, participants made more exculpatory judgments about transgressions they committed than they did about transgressions others committed, but participants did not judge transgressions committed against them more harshly than they judged transgressions committed against others. The higher participants scored on Kohlberg's test the less they externalized and excused their moral transgressions. Contrary to expectation, this relation also applied to moral judgments about transgressions committed by others against others. These findings have important implications for models of moral development and social cognition.     

FOK产生机制的实验研究

通过以初中生和大学生为被试的两个实验探讨了FOK（Feeling-of-Knowing即“熟知感”）的产生机制,是线索熟悉性还是靶项目的可提取性（或记忆强度）决定FOK判断的等级。识记材料为90对中文词对.分前后两部分让被试识记,前后两部分词对之间安排三种关系：①完全相同;②仅线索词相同,③完全不同,这三种关系可选成不同的靶项目记忆强度和不同的线索熟悉性.两组实验结果一致表明,FOK的等级判断的高低取决于线索熟悉程度,而不随靶项目的记忆强度而变化.
