This document contains the abstracts for the 2018 Scandinavian Workshop on Applied Eye Tracking (SWAET 2018) which was held at Copenhagen Business School, Denmark, 23 to 24 August, 2018..

David Deutsch (forthcoming) offers a solution to the Epistemic Problem for Everettian Quantum Theory. In this note I raise some problems for the attempted solution.

Abstract: This paper proposes to carve out a new position in the scientific realism/antirealism debate and argue that it captures some of the most important realist and some of the most important antirealist considerations. The view, briefly stated, is that there is always a fact of the matter about whether the singular statements science gives us are literally true, but there is no fact of the matter about whether the non-singular statements science gives us are literally true. I call this view singularist semirealism. Singularist semirealism sides with scientific realism with regards to singular statements but it is an antirealist view with regards to non-singular statements. In this sense, singularist semirealism could be considered to be 'the best of both worlds'.

AbstractWith its origin in the Samveda, composed between 1500–900 BC, the art music of India has evolved through ages and come to be regarded as one of the oldest surviving music systems in the world today. This paper aims to provide an overview of the fundamentals governing Hindustani music (also known as North Indian music) as practiced today. The deliberation will mainly focus on the melodic aspect of music making and will attempt to provide a musicological base for the main features associated with the melody: intonation and improvisation; thus covering the soundscape on the micro as well as macro level. The larger objective of this endeavour is to identify relevant directions for the application of computational approaches to Hindustani music.

This paper focuses on social perception, an area of research that lies at the interface between the philosophy of perception and the scientific investigation of human social cognition. Some philosophers and psychologists appeal to resonance mechanisms to show that intentional and goal-directed actions can be perceived. Against these approaches, I show that there is a class of simple goal-directed actions, whose perception does not rely on resonance. I discuss the role of the STS (superior temporal sulcus) as the possible neural correlate of perception of goal-directed actions. My proposal is intermediate between claims according to which we perceive intentional actions and claims according to which we cannot perceive goal-directed actions.

The reward system of science is the priority rule. The first scientist making a new discovery is rewarded with prestige, while second runners get little or nothing. Michael Strevens, following Philip Kitcher, defends this reward system, arguing that it incentivizes an efficient division of cognitive labor. I argue that this assessment depends on strong implicit assumptions about the replicability of findings. I question these assumptions on the basis of metascientific evidence and argue that the priority rule systematically discourages replication. My analysis leads us to qualify Kitcher and Strevens’s contention that a priority-based reward system is normatively desirable for science.

Summary Can preverbal infants utilize logical reasoning such as disjunctive inference? This logical operation requires keeping two alternatives open (A or B), until one of them is eliminated (if not A), allowing the inference: B is true. We presented to 10-month-old infants an ambiguous situation in which a female voice was paired with two faces. Subsequently, one of the two faces was presented with the voice of a male. We measured infants' preference for the correct face when both faces and the initial voice were presented again. Infant pupillary response was measured and utilized as an indicator of cognitive load at the critical moment of disjunctive inference. We controlled for other possible explanations in three additional experiments. Our results show that 10-month-olds can correctly deploy disjunction and negation to disambiguate scenes, suggesting that disjunctive inference does not rely on linguistic constructs. Highlights • 10-month-old infants have no logical operators in their lexicon • Nevertheless, they can use logical deduction in case of an ambiguous situation • They correctly deduce which faces and voices are paired through disjunctive inference • Infants' performance in this task can be followed by measuring their pupil dilation Biological Science, Neuroscience, Cognitive neuroscience, Behavioral Neuroscience Graphical abstract

Abstract Sound patterns in heritage languages are often highly variable, potentially with influences from majority languages. Yet, the core phonological system of the heritage language tends to remain stable. This article considers variation in the phonetic and phonological patterns of /r/ in American Norwegian heritage language speakers from neighboring communities in western Wisconsin, in the Upper Midwestern United States. Drawing on acoustic data from speakers born between 1879 and 1957, I examine the distribution of four rhotic allophones, including an English-like approximant, over time. These data reveal an increase of approximants that is structured within the Norwegian phonological system and its processes. Furthermore, analyzing these changes with the proposed modular framework provides clarity for how heritage language sound systems do and do not change under contact and contributes to our understanding of the asymmetric phonetic and phonological heritage language patterns.

It is known that, although the level of light is the primary determinant of pupil size, cognitive factors can also affect pupil diameter. It has been demonstrated that photographs of the sun produce pupil constriction independently of their luminance and other low-level features, suggesting that high-level visual processing may also modulate pupil response. Here, we measure pupil response to artistic paintings of the sun, moon, or containing a uniform lighting, that, being mediated by the artist's interpretation of reality and his technical rendering, require an even higher level of interpretation compared with photographs. We also study how chromatic content and spatial layout affect the results by presenting grey-scale and inverted versions of each painting. Finally, we assess directly with a categorization test how subjective image interpretation affects pupil response. We find that paintings with the sun elicit a smaller pupil size than paintings with the moon, or paintings containing no visible light source. The effect produced by sun paintings is reduced by disrupting contextual information, such as by removing color or manipulating the relations between paintings features that make more difficult to identify the source of light. Finally, and more importantly, pupil diameter changes according to observers' interpretation of the scene represented in the same stimulus. In conclusion, results show that the subcortical pupillary response to light is modulated by subjective interpretation of luminous objects, suggesting the involvement of cortical systems in charge of cognitive processes, such as attention, object recognition, familiarity, memory, and imagination.
