Vespula germanica and Vespula vulgaris are two common European wasps that have ecological and economic importance as a result of their artificial introduction into many different countries and environments. Their success has undoubtedly been aided by their capacity for visually guided hunting, foraging, learning and using visual cues in the context of homing and navigation. However, the visual sys

To investigate multimodal signals in cat–human communication we recorded 36 cat–owner interactions in everyday situations that were judged by the owners for valence (negative, mixed or positive). We then coded the videos for behaviour using an ethogram including vocal, visual and tactile (multimodal) signals. Vocalisations were segmented and acoustic measures of duration and F0 obtained. In cats,

Background: Few neuroimaging studies have investigated structural brain differences associated with variations in pain distribution. Objective: To explore structural differences of the brain in fibromyalgia (FM), temporomandibular disorder pain (TMD) and healthy pain-free controls (CON) using structural and diffusion MRI. Methods: A case–control exploratory study with three study groups with diffe

Research has shown that speakers of different languages may differ in their cognitive and perceptual processing of reality. A common denominator of this line of investigation has been its reliance on the sensory domain of vision. The aim of our study was to extend the scope to a new sense—taste. Using as a starting point crosslinguistic differences in the category boundaries of edible bulbs, we ex

This chapter provides an overview of current research on thinking-for-speaking and second language acquisition. The Thinking-for-Speaking hypothesis (Slobin, 1996) posits that whilst in the process of producing speech, speakers channel their attention according to the linguistic categories of their language. As a result, speakers of different languages think differently during speech production. W

This chapter reviews the available empirical evidence for a universal metaphoric structure such as TIME IS SPACE and its effects on temporal cognition in L2 users. The chapter covers previous experimental evidence that lends support to the psychological reality of the TIME IS SPACE metaphor, while also revealing cross-linguistic differences in how this fundamental metaphor is instantiated across t

The temporal focus hypothesis (TFH) entails that individuals who value the past tend to conceptualize it in front, whereas individuals who value the future tend to map the future in front instead (de la Fuente et al., 2014). This varies as a function of culture, individual differences, and context. Here, we extend this line of inquiry by testing a contextual variable, namely COVID-19 quarantine st

This study investigated whether the brain utilizes morphologically induced tones for semantic processing during online speech perception. An auditory comprehension task was conducted while measuring event-related potentials (ERPs). The study tested whether a discrepancy between contextual expectations and the tonal realizations of the target word would yield an N400 effect, indicative of semantic

This paper examines the linguistic relativity principle (Whorf, 1956) by investigating the impact of grammatical gender on cognition in simultaneous bilinguals of three-gendered Ukrainian and Russian. It examines whether speakers of three-gendered languages show grammatical gender effects on categorisation, empirically addressing claims that such effects are insignificant due to the presence of th

The Editors’ and Readers’ Choice Awards were established in 2022 to celebrate some of the outstanding articles published every year in the Journal of Comparative Physiology A. The recipients of the 2024 Editors’ Choice Awards were selected based on votes cast by the Editorial Board on articles published in 2023. In the category Original Paper, this distinction goes to ‘Views from ‘crabworld’: the

In this study, we investigated the prosody of domestic cat meows produced in different contexts. Prosodic cues – i.e., variation in intonation, duration, voice quality and fundamental frequency – in humans as well as in nonhuman animals carry information about idiosyncratic traits of the signaller, including sex, age, and physical and mental state. The duration, fundamental frequency (F0) and into

Deep convolutional neural networks (CNNs) have been shown to predict poverty and development indicators from satellite images with surprising accuracy. This paper presents a first attempt at analyzing the CNNs responses in detail and explaining the basis for the predictions. The CNN model, while trained on relatively low resolution day- and night-time satellite images, is able to outperform human

This study explored how non-signers exploit their gestural repertoire during a process of handshape conventionalisation. We examined how communicative context, interaction and time affect the transition from iconically-motivated representations to linguistically-organised, generalised forms. 100 non-signers undertook a silent gesture-elicitation task, describing pictures in one of four conditions:

Purpose: The aim of this study is to explore teachers’ experience and understanding of classroom communication after participating in a speech-language pathologist (SLP) led in-service training on classroom communication. Method: This qualitative study used a focus group approach to explore how teachers describe their classroom communication. Twenty primary-school teachers participated. Thematic a

Diary methods have long been used as pedagogic tools in learning, and as part of reflective practice in teacher education, but less often as data collection instruments in educational research. This is in part due to implementation challenges emerging from the time and literacy demands they place on participants. To illustrate the use of diary methods in educational research, we juxtapose two diar

This study examines the effects of teachable agents’ expressed self-efficacy on students. A total of 166 students, 10- to 11-years-old, used a teachable agent-based math game focusing on the base-ten number system. By means of data logging and questionnaires, the study compared the effects of high vs. low agent self-efficacy on the students’ in-game performance, their own math self-efficacy, and t

Perception is not a passive process but the result of an interaction between an organism and the environment. This is especially clear in haptic perception that depends entirely on tactile exploration of an object. We investigate this idea in a system-level brain model of somatosensory and motor cortex and show how it can use signals from a humanoid robot to categorize different object. The model
