Epistemic perceptualism and neo-sentimentalist objections

Epistemic Perceptualists claim that emotions are sources of immediate defeasible justification for evaluative propositions that can (and do) sometimes ground undefeated immediately justified evaluative beliefs. For example, fear can constitute the justificatory ground for a belief that some object or event is dangerous. Despite its attractiveness, the view is apparently vulnerable to several objections. In this paper, I provide a limited defence of Epistemic Perceptualism by responding to a family of objections which all take as a premise a popular and attractive view in value theory – Neo-Sentimentalism – according to which values are analysed in terms of fitting emotions.     

面孔吸引力观察者参照:“角度效应”的眼动研究

以标准的黑白面孔图片作为实验材料,让41名大学生观看不同倾斜角度(左倾、竖直和右倾)的面孔图片,并对之进行面孔吸引力的评价,同时用眼动仪记录被试的眼动数据。结果显示:(1)被试观看左倾和右倾面孔的平均瞳孔大小显著小于观看竖直面孔的平均瞳孔大小,观看左倾面孔的平均瞳孔大小显著大于右倾面孔;(2)被试对左倾和右倾面孔的平均注视时间显著短于对竖直面孔的平均注视时间,同时对左倾面孔的注视时间显著长于右倾面孔;(3)被试对左倾和右倾面孔的平均注视次数显著少于对竖直面孔的平均注视次数。实验结果表明,面孔的倾斜角度很可能是影响面孔吸引力的一个重要因素,在面孔吸引力的审美偏好中存在"角度效应",即竖直面孔的吸引力高于倾斜面孔的吸引力,左倾面孔的吸引力高于右倾面孔的吸引力。     

Linguistic and prosodic aspects of child-directed speech: The role of maternal child-rearing experiences

This study explored if the quality of mothers’ reported child-rearing experiences influences the prosodic and linguistic features of maternal child-directed speech. Lexical, syntactic, functional and prosodic aspects of maternal speech directed towards their 24-month-old children were examined. Results showed that mothers with different child-rearing histories differed in the ways they talked to their children. Mothers who recalled the caregiving they received during childhood as characterized by high levels of care and low levels of control, used a lexically and syntactically more complex speech and expressed more positive emotions. This kind of input seems to be more attuned with the typical growing skills of two-year-old children. Implications for the study of mother–infant relationship as well as for the study of child language development are addressed.     

汉语成语谜语问题解决中思路竞争的眼动研究

在谜语问题解决过程中, 可能存在着通过简单联想和新异联想寻找答案这两种思路。两个实验中设置了包括寻常答案与新颖答案在内的若干备择答案(实验1为4个, 实验2为6个)供被试选择, 利用眼动技术记录被试在解题过程中的不同时间段内对新颖答案与寻常答案的平均注视时间, 考察汉语成语谜语问题解决中两种思路之间冲突的过程。实验1操纵了任务要求, 实验2操纵了规则线索的有效性。实验结果表明：(1)在成语谜语问题解决中的一段时间内新异联想和简单联想能够同时发生且形成竞争; (2)选择“新颖且合适答案”的任务要求, 提高了成功形成新颖语义联结的概率, 但是并没有加快新异联想发生、发展的进程, 也没有改变两种思路相互竞争的局面; (3)有效的规则线索可以抑制简单联想, 阻止其发生, 同时可以加快新异联想发生、发展的进程。     

合理性对汉语阅读中双字词语义预视效益的优势作用：眼动研究

语义预视效益(SPB)对于揭示阅读中读者能否从副中央凹提取高水平信息具有重要意义。关于SPB的产生机制仍然存在争议。本研究通过同时操控预视词的合理性和语义相关性考察了二者对汉语阅读中双字词SPB的影响。结果发现,合理性主效应显著,合理预视下目标词的注视时间显著短于不合理预视;语义相关性主效应不显著,未发现二者的交互作用。研究结果支持了语境匹配假说,进一步说明了汉语阅读中预视词的合理性对SPB的优势作用。     

Mixing virtue and vice: combining the immediacy effect and the diversification heuristic

Many of the most significant choices that people make are between vices, which exchange small immediate rewards for large delayed costs, and virtues, which exchange small immediate costs for large delayed rewards. We investigate the consequences of making a series of such choices either simultaneously or sequentially. We made two predictions. First, because many alternatives chosen under simultaneous choice will only be experienced following a delay, and because hyperbolic time discounting predicts that people will prefer delayed virtues but immediate vices, we predicted that people would choose more virtues in simultaneous than sequential choice. Second, due to the tendency to diversify portfolios of choices, we predicted a greater mix of virtues and vices in simultaneous than sequential choice. These predictions were confirmed in two experiments involving real choices; one between ‘highbrow’ and ‘lowbrow’ movies, and the other between ‘instant‐win’ and ‘prize‐draw’ lottery tickets. We conclude by posing the question of whether simultaneous or sequential choice results in decisions that more closely approximate what people ‘really’ want.

De‐legitimizing hostility and strengthening joint agency: Lutheran inter‐religious commitment today

The ELCA Declaration of Inter‐Religious Commitment is an important instrument for mainstreaming inter‐religious engagement in local communities and diverse ministries. This article assesses this recent policy document and highlights how the text engages Lutheran theological reasoning on “the neighbor” for a profound understanding of God's grace, theologically de‐legitimizes hostility and exclusion, and strengthens joint agency. This resonates with current concerns in the global Lutheran communion and the wider ecumenical movement.     

Movement Speed and Accuracy in Space and Time: The Complementarity of Error Distributions

Movement speed-accuracy trade-off is a function of the space-time constraints of the task. We investigated the space-time account of Hancock and Newell (1985) and the hypothesis of complementarity between the four moments of the error distribution in space and time. Twelve participants performed 15 conditions in a line drawing task composed of different spatial (10, 20, and 30 cm) and temporal (250 to 2,500 ms) criteria. The results showed that all moments of distributions changed systematically between conditions but there were some departures from the Hancock and Newell predictions. In contrast, individual analysis revealed the complementarity of the spatial and temporal error including a trade-off between the four moments of error. These findings support a complementary space-time account of movement speed and accuracy.     

Postural control,falls and Parkinson’s disease: Are fallers more asymmetric than non-fallers?

Postural control asymmetry is an important aspect of Parkinson’s disease (PD) that may be associated with falls. The aim of this study was to compare the postural control asymmetry during postural tasks between fallers and non-fallers in people with PD and neurological healthy age-matched controls (CG). Individuals with idiopathic PD (n = 24) and CG (n = 24) were sub-divided into groups of fallers and non-fallers based on their fall history over the past year. Participants performed blocks of three 30-s trials of quiet standing with feet in a side-by-side and semi-tandem stance position. The center of pressure parameters for each limb were measured and used to calculate the symmetry index. Fallers compared to non-fallers had decreased asymmetry of vertical force in the side-by-side condition. During the tandem-front leg condition, PD non-fallers increased asymmetry of the medial-lateral velocity of sway compared to CG non-fallers. In addition, for the tandem–back leg condition, PD non-fallers increased asymmetry of total displacement and medial-lateral root mean square and mean velocity of sway compared to PD fallers. The results of the study did not support the hypothesis that PD fallers are more asymmetric than PD non-fallers. On the contrary, our results indicated that PD non-fallers had higher postural control asymmetry, especially during the more challenging (semi-tandem standing) postural task.
