Retroactive adjustment of perceived time

Accurately timing acoustic events in dynamic scenes is fundamental to scene analysis. To detect events in busy scenes, listeners must often identify a change in the pattern of ongoing fluctuation, resulting in many ubiquitous events being detected later than when they occurred. This raises the question of how delayed detection time affects the manner in which such events are perceived relative to other events in the environment.To model these situations, we use sequences of tone-pips with a time–frequency pattern that changes from regular to random (‘REG–RAND’) or vice versa (‘RAND–REG’). REG–RAND transitions are detected rapidly, but the emergence of regularity cannot be established immediately, and thus RAND–REG transitions take significantly longer to detect. Using a temporal order judgment task, and a light-flash as a temporal marker, we demonstrate that listeners do not perceive the onset of RAND–REG transitions at the point of detection (∼530 ms post transition), but automatically re-adjust their estimate ∼300 ms closer to the nominal transition.These results demonstrate that the auditory system possesses mechanisms that survey the proximal history of an ongoing stimulus and automatically adjust perception to compensate for prolonged detection time, allowing listeners to build meaningful representations of the environment.     

Prominence vs. aboutness in sequencing: A functional distinction within the left inferior frontal gyrus

Prior research on the neural bases of syntactic comprehension suggests that activation in the left inferior frontal gyrus (lIFG) correlates with the processing of word order variations. However, there are inconsistencies with respect to the specific subregion within the IFG that is implicated by these findings: the pars opercularis or the pars triangularis. Here, we examined the hypothesis that the dissociation between pars opercularis and pars triangularis activation may reflect functional differences between clause-medial and clause-initial word order permutations, respectively. To this end, we directly compared clause-medial and clause-initial object-before-subject orders in German in a within-participants, event-related fMRI design. Our results showed increased activation for object-initial sentences in a bilateral network of frontal, temporal and subcortical regions. Within the lIFG, posterior and inferior subregions showed only a main effect of word order, whereas more anterior and superior subregions showed effects of word order and sentence type, with higher activation for sentences with an argument in the clause-initial position. These findings are interpreted as evidence for a functional gradation of sequence processing within the left IFG: posterior subportions correlate with argument prominence-based (local) aspects of sequencing, while anterior subportions correlate with aboutness-based aspects of sequencing, which are crucial in linking the current sentence to the wider discourse. This proposal appears compatible with more general hypotheses about information processing gradients in prefrontal cortex (Koechlin & Summerfield, 2007).     

Second order change and evidence‐based practice

Since its inception, family therapy (FT) has been distinguished by its explicit theoretical and practical focus on families and relationships as systems, with an emphasis on second order rather than first order change. As a result of these conceptual underpinnings we suggest that FT needs to look for manifestations of change which differ from individually focused disciplines such as clinical psychology. Studies of second order change have most commonly appeared in the form of conceptual papers and doctoral dissertations. We begin by revisiting the conceptual underpinnings of second order change. Building on this framework, we develop these aspects of change within the framework of recent developments in the empirical study of change. Finally, we point towards some promising directions for further evaluative work of FT as well as ways to incorporate some of these principles into training of FT students.     

Individual differences in (non-visual) processing style predict the face inversion effect

Recent research suggests that individuals with relatively weak global precedence (i.e., a smaller propensity to view visual stimuli in a configural manner) show a reduced face inversion effect (FIE). Coupled with such findings, a number of recent studies have demonstrated links between an advantage for feature-based processing and the presentation of traits associated with autism among the general population. The present study sought to bridge these findings by investigating whether a relationship exists between the possession of autism-associated traits (i.e., as indicated by individuals'"autism quotient" [(AQ) and the size of the FIE. Participants completed an on-line study in which the AQ was measured prior to a standard face recognition task where half of the faces were inverted at test. The results confirmed that higher AQ levels were predictive of smaller FIEs. Implications for a common underlying factor relating to processing orientation are discussed.     

A Bayesian Model of Biases in Artificial Language Learning: The Case of a Word‐Order Universal

In this article, we develop a hierarchical Bayesian model of learning in a general type of artificial language‐learning experiment in which learners are exposed to a mixture of grammars representing the variation present in real learners’ input, particularly at times of language change. The modeling goal is to formalize and quantify hypothesized learning biases. The test case is an experiment ( Culbertson, Smolensky, & Legendre, 2012 ) targeting the learning of word‐order patterns in the nominal domain. The model identifies internal biases of the experimental participants, providing evidence that learners impose (possibly arbitrary) properties on the grammars they learn, potentially resulting in the cross‐linguistic regularities known as typological universals. Learners exposed to mixtures of artificial grammars tended to shift those mixtures in certain ways rather than others; the model reveals how learners’ inferences are systematically affected by specific prior biases. These biases are in line with a typological generalization—Greenberg's Universal 18—which bans a particular word‐order pattern relating nouns, adjectives, and numerals.     

If you have a choice,you have trouble: Stimulus valence modulates presentation‐order effects in preference judgment

It is well known that the presentation order of choice options often affects decision outcomes to a significant degree. However, despite the significance and wide occurrence of the effects, they are ignored in most preference models. Furthermore, psychophysical findings of stimulus‐magnitude dependent presentation‐order effects have not been acknowledged previously in the cognitive literature on preference judgments. Thus, the potential moderating effect of the level of stimulus magnitude (here, valence) on the direction and size of order effects in preference judgment has not been investigated previously. In two experiments, participants (117 and 204, respectively) rated their preference for pairs of everyday‐type objects and phenomena (e.g., apple–pear, headache–stomachache). Stimuli were spaced horizontally, and each participant received them in one of two opposite within‐pair presentation orders. Participants also rated the stimuli's valence on a scale from very bad to very good. The results showed a positive correlation between the rated valence and the tendency to prefer the first‐mentioned (left) stimulus; that is, the effect was greatest, and opposite, for choices between the most attractive and the most unattractive options, respectively. In terms of Hellström's ( 1979 ) sensation‐weighting model, the positive correlation is caused by a higher weight (i.e., impact on the preference judgment) for the left stimulus than for the right, which is possibly due to the left stimulus being compared to the right. The results suggest that researchers may have failed previously to find important moderators of presentation‐order effects in preference judgment due to the failure to use sufficiently attractive or unattractive stimuli.

发散思维的序列位置效应：创新想法动态产生机制的新视角

发散思维的序列位置效应是指随着时间的推移,单位时间内想法生成的数量逐渐降低,但想法的独创性逐渐升高的现象。联想理论和执行控制假说分别侧重对序列位置效应的个体差异和认知加工过程进行解释。神经影像学研究表明,在想法产生的整个阶段序列位置效应依赖于默认网络后部和突显网络的持续增强激活和协同合作;在想法产生的后期阶段,颞-顶区域alpha能量值以及执行控制网络与默认网络的协同模式增强。未来研究需要结合语义和神经动态分析等技术,对序列位置效应的特异性机制、动态加工机制以及影响因素进行深入探究,从而为解构创新思维的动态过程提供新的视角。     

Contingency and changing reality: Perspectives from Germany

The World Wide Web connects less and disconnects more. In Germany as in the United States, disconnecting factions digitize their ideologies and overnight multiply their adherents. Such forces of disruption are incessant. Appeal to constructivist theory reveals that beneath this destabilizing dynamic is awareness of contingency, the feeling of disempowerment in the face of an unpredictable and uncontrollable future. Religion has the potential for stabilizing, but religious leaders will need to reignite a faith in the future to make this happen.     

The Cross versus the Crescent: Karl Kumm’s Missiology

ABSTRACT

This article surveys the missiology promoted in the writings of the Protestant missionary Karl Kumm during the first decades of the twentieth century. Kumm was famous as a missionary explorer. He was the first European to successfully cross the region known as the Sudan, from the Niger bend to the Nile. He was also notable because he founded two different missions in two different places in Africa, both aimed at evangelizing the peoples of the Sudan. Lastly, Kumm was significant for having constructed in his various writings a highly influential case against the evangelization of Muslims and for the evangelization of traditionalist people. Kumm, his ideas and actions helped shape government policy towards Christian missions and Christian–Muslim relations in colonial Northern Nigeria.     

JUSTICE AS INHERENT RIGHTS: A RESPONSE TO MY COMMENTATORS

The critical comments by my fellow symposiasts on my book, Justice: Rights and Wrongs , have provided me with the opportunity to clarify parts of my argument and to correct some misunderstandings; they have also helped me see more clearly than I did before the import of some parts of my argument. In his comments, Paul Weithman points out features of the right order conception of justice that I had not noticed. They have also prodded me to clarify in what way rights are trumps; and both his comments and Bernstein's have prodded me to clarify certain aspects of the theistic account of human rights that I offered. Attridge's comments lead me to see that I was perhaps over-zealous in emphasizing the objective aspects of the semantic range of dikaiosunê as used in the New Testament and downplaying the subjective aspects. And O'Donovan's comments have provided me with the opportunity to make clear that my account of rights is not an immunities account that presupposes nominalism, and to emphasize the ways in which it is not an asocial individualistic account.
