Neural correlates of sensory‐enabling presentation: An fMRI study of image zooming and rotation video effects on online apparel shopping

For experience products, such as apparel, sensory‐enabling presentations that provide a sense of tactile experience have been suggested as an effective strategy to reduce perceived risk and increase the likelihood of a pleasurable shopping experience. Using functional Magnetic Resonance Imaging (fMRI), we investigated whether sensory‐enabling presentations, specifically, image zooming and rotation videos, would evoke different cognitive and affective brain functions during product evaluation and purchase decision processes. The results suggested that whereas image zooming may evoke more visual perception in the product evaluation process, the rotation view evokes more mental imagery, pleasure, and reward anticipation during the purchase decision process.

On the Algebraizability of the Implicational Fragment of Abelian Logic

In this paper we consider the implicational fragment of Abelian logic \({{{\sf A}_{\rightarrow}}}\) . We show that although the Abelian groups provide an semantics for the set of theorems of \({{{\sf A}_{\rightarrow}}}\) they do not for the associated consequence relation. We then show that the consequence relation is not algebraizable in the sense of Blok and Pigozzi (Mem Am Math Soc 77, 1989). In the second part of the paper, we investigate an extension of \({{{\sf A}_{\rightarrow}}}\) in the same language and having the same set of theorems and show that this new consequence relation is algebraizable with the Abelian groups as its equivalent algebraic semantics. Finally, we show that although \({{{\sf A}_{\rightarrow}}}\) is not algebraizable, it is order-algebraizable in the sense of Raftery (Ann Pure Appl Log 164:251–283, 2013).     

Optimisation and mathematical explanation: doing the Lévy Walk

The indispensability argument seeks to establish the existence of mathematical objects. The success of the indispensability argument turns on finding cases of genuine extra-mathematical explanation (the explanation of physical facts by mathematical facts). In this paper, I identify a new case of extra-mathematical explanation, involving the search patterns of fully-aquatic marine predators. I go on to use this case to predict the prevalence of extra-mathematical explanation in science.     

Comparing methods for measuring peak look duration: Are individual differences observed on screen-based tasks also found in more ecologically valid contexts?

Convergent research points to the importance of studying the ontogenesis of sustained attention during the early years of life, but little research hitherto has compared and contrasted different techniques available for measuring sustained attention. Here, we compare methods that have been used to assess one parameter of sustained attention, namely infants’ peak look duration to novel stimuli. Our focus was to assess whether individual differences in peak look duration are stable across different measurement techniques. In a single cohort of 42 typically developing 11-month-old infants we assessed peak look duration using six different measurement paradigms (four screen-based, two naturalistic). Zero-order correlations suggested that individual differences in peak look duration were stable across all four screen-based paradigms, but no correlations were found between peak look durations observed on the screen-based and the naturalistic paradigms. A factor analysis conducted on the dependent variable of peak look duration identified two factors. All four screen-based tasks loaded onto the first factor, but the two naturalistic tasks did not relate, and mapped onto a different factor. Our results question how individual differences observed on screen-based tasks manifest in more ecologically valid contexts.

Urgently Yours: Temporal Communication Norms and Psychological Distance

Communicators have at their disposal an ever‐increasing variety of modalities by which to transmit messages. Do the prominent norms attached to different communication modalities contain information in and of themselves? The present investigation considers this question through the lens of text messages and emails, hypothesized to confer different normative information about urgency. Text messages (vs. emails)—or any communication inferred by receivers to have been sent with greater urgency—cause the content of those messages to seem, in the eyes of receivers, closer in time (Study 1), closer in space (Study 2), and more likely to occur (Study 3). Moderation and mediation analyses confirm the role of urgency underlying the relationship between modality and distance. We provide evidence for these effects in a series of laboratory studies together with a field study in which real text messages and emails impact not only inferred distance but also a behavior deriving therefrom. Theoretical and practical implications highlight the importance, for both researchers and practitioners, of understanding how the medium of communication can shape interpretation of the message.
