Temporal order perception of auditory stimuli is selectively modified by tonal and non-tonal language environments

The close relationship between temporal perception and speech processing is well established. The present study focused on the specific question whether the speech environment could influence temporal order perception in subjects whose language backgrounds are distinctively different, i.e., Chinese (tonal language) vs. Polish (non-tonal language). Temporal order thresholds were measured for both monaurally presented clicks and binaurally presented tone pairs. Whereas the click experiment showed similar order thresholds for the two language groups, the experiment with tone pairs resulted in different observations: while Chinese demonstrated better performance in discriminating the temporal order of two “close frequency” tone pairs (600 Hz and 1200 Hz), Polish subjects showed a reversed pattern, i.e., better performance for “distant frequency” tone pairs (400 Hz and 3000 Hz). These results indicate on the one hand a common temporal mechanism for perceiving the order of two monaurally presented stimuli, and on the other hand neuronal plasticity for perceiving the order of frequency-related auditory stimuli. We conclude that the auditory brain is modified with respect to temporal processing by long-term exposure to a tonal or a non-tonal language. As a consequence of such an exposure different cognitive modes of operation (analytic vs. holistic) are selected: the analytic mode is adopted for “distant frequency” tone pairs in Chinese and for “close frequency” tone pairs in Polish subjects, whereas the holistic mode is selected for “close frequency” tone pairs in Chinese and for “distant frequency” tone pairs in Polish subjects, reflecting a double dissociation of function.     

Here Today,Gone Tomorrow? Assessing How Timing and Repetition of Scandal Information Affects Candidate Evaluations

Scholars and political consultants alike know that during a campaign even the hint of a scandal has the potential to distract from a candidate's policy messages—or even worse—can have dire consequences on Election Day. But does it matter whether the scandal breaks early as opposed to late in the campaign? And how do citizens respond when the scandal drags on for weeks? This study represents the first effort to shed light on these temporal dynamics. Results reveal that timing affects the immediate impact of scandal information, the rate at which those initial effects decay, and candidate evaluations offered at the campaign's conclusion. Additionally, I develop two competing hypotheses regarding how citizens may process scandal information when it is repeated throughout a campaign. Empirical tests suggest that voters eventually reach a saturation threshold after which additional repetition of scandal information has negligible effects on evaluations unless new details are a prominent feature of ongoing coverage, in which case repetition can extend the negative effects of scandal.     

A threshold theory account of psychometric functions with response confidence under the balance condition

The study of thresholds for discriminability has been of long‐standing interest in psychophysics. While threshold theories embrace the concept of discrete‐state thresholds, signal detection theory discounts such a concept. In this paper we concern ourselves with the concept of thresholds from the discrete‐state modelling viewpoint. In doing so, we find it necessary to clarify some fundamental issues germane to the psychometric function (PF), which is customarily constructed using psychophysical methods with a binary‐response format. We challenge this response format and argue that response confidence also plays an important role in the construction of PFs, and thus should have some impact on threshold estimation. We motivate the discussion by adopting a three‐state threshold theory for response confidence proposed by Krantz (1969, Psychol. Rev., 76, 308–324), which is a modification of Luce's (1963, Psychol. Rev., 70, 61–79) low‐threshold theory. In particular, we discuss the case in which the practice of averaging over order (or position) is enforced in data collection. Finally, we illustrate the fit of the Luce–Krantz model to data from a line‐discrimination task with response confidence.     

The Baltimore Mural Project: An approach to threshold concepts in religious studies

The Baltimore Mural Project (BMP) seeks to connect religious studies education to the growing literature on threshold concepts in order to address bottleneck areas in student learning. The project is designed for undergraduate service courses comprised of mostly non‐majors: for example, world religions. Students in these courses often struggle to understand and apply the discipline's unique approaches to the study of religion (i.e. its threshold concepts). Rather than merely memorize certain facts about a religious tradition's myths [or world forming stories], rituals [or embodied disclosures], materials, and so on... students are asked to apply threshold concepts related to religion, art, and the social good to the study of murals in Baltimore. Through a series of project elements (including: field work, photography, digital geomapping, and quantitative, qualitative, and archival research) the BMP helps students who struggle with threshold concepts in religious studies by creatively connecting the more conventional aspects of world religions courses to social justice issues related to mural art in Baltimore. By experientially helping students to make these connections, they are able to find creative routes through otherwise hindering barriers to their learning in religious studies.     

Evaluative conditioning depends on higher order encoding processes

Evaluative conditioning (EC) is commonly conceived as stimulus-driven associative learning. Here, we show that internally generated encoding activities mediate EC effects: Neutral conditioned stimuli (CS) faces were paired with positive and negative unconditioned stimuli (US) faces. Depending on the encoding task (Is CS a friend vs. enemy of US?), Experiment 1 yielded either normal EC effects (CS adopting US valence) or a reversal. This pattern was conditional on the degree to which encoding judgements affirmed friend or enemy encoding schemes. Experiments 2a and 2b replicated these findings with more clearly valenced US faces and controlling for demand effects. Experiment 3 demonstrated unconditional encoding effects when participants generated friend or enemy relations between CS and US faces. Explicitly stated friend or enemy relations in Experiment 4 left EC effects unaffected. Together, these findings testify to the importance of higher order cognitive processes in conditioning, much in line with recent evidence on the crucial role of conditioning awareness.     

Do production patterns influence the processing of speech in prelinguistic infants?

The headturn preference procedure was used to test 18 infants on their response to three different passages chosen to reflect their individual production patterns. The passages contained nonwords with consonants in one of three categories: (a) often produced by that infant (‘own’), (b) rarely produced by that infant but common at that age (‘other’), and (c) not generally produced by infants. Infants who had a single ‘own’ consonant showed no significant preference for either ‘own’ (a) or ‘other’ (b) passages. In contrast, infants’ with two ‘own’ consonants exhibited greater attention to ‘other’ passages (b). Both groups attended equally to the passage featuring consonants rarely produced by infants of that age (c). An analysis of a sample of the infant-directed speech ruled out the mothers’ speech as a source of the infant preferences. The production-based shift to a focus on the ‘other’ passage suggests that nascent production abilities combine with emergent perceptual experience to facilitate word learning.     

Of Power and Compassion

Abstract: While military and economic power are obviously central instruments of policy in international relations, there are a number of reasons why power alone is insufficient to succeed in fighting terrorism. Three central reasons are discussed in this essay: the limitations and the dilemma of power; the proposition that the most threatening form of terrorism, such as al‐Qaeda's, is conducted by nonstate actors, conventional deterrence against whom is less effective; and the role of motivation in conflicts where the distribution of power is asymmetrical. In addition to these objective reasons, it is argued that the foreign‐policy strategies pursued ultimately affect the actors' own values.     

Internal Realism and the Problem of Religious Diversity

This article applies Hilary Putnam’s theory of internal realism to the issue of religious plurality. The result of this application – ‘internalist pluralism’ – constitutes a paradigm shift within the Philosophy of Religion. Moreover, internalist pluralism succeeds in avoiding the major difficulties faced by John Hick’s famous theory of religious pluralism, which views God, or ‘the Real,’ as the noumenon lying behind diverse religious phenomena. In side-stepping the difficulties besetting Hick’s revolutionary Kantian approach, without succumbing to William Alston’s critique of conceptual-scheme dependence, internalist pluralism provides a solution to significant theoretical problems, while doing so in a manner that is respectful of cultural diversity and religious sensitivities.

A new Bayesian procedure for the estimation of the referees' decision thresholds and agreement. The case of professional handball refereeing

In double refereeing, agreement between referees is fundamental for the achievement of a flawless and smooth refereeing activity. Nonetheless, the agreeement can be affected by several external and internal factors, with a negative impact on the consistency of the refereeing and the fluidity of the game. The referee’s Decision Threshold (DT) is the limit above which the evidence of a foul results in the call of an infraction by the referee. It represents the individual refereeing style, and it is one of the factors that can contribute to low agreement between the referees. We present an application of a new Bayesian procedure to estimate referee’s DT in a typical refereeing task. To this end, 56 italian professional handball (FIGH) referees were asked to evaluate 96 potential foul plays, belonging to four different infraction types: 7-m throw, passive play, offensive foul, disciplinary sanctions. The proposed method provides information about: (i) referee’s individual DT; (ii) the agreement between pairs of referees (i.e., one-to-one); (iii) the agreement between each referee and all the other referees (i.e., one-to-total); (iv) the agreement between each referee and a reference referee (i.e., one-to-expert); (v) the proportion of agreement between the referees and a reference referee for each potential foul play. Sport federations would profit by this procedure in different ways: by using the information about the DT to train referees, by detecting referees with a low agreement with their colleagues or with the reference referee, by focusing training on specific plays to improve the arbitration class internal consistency.
