Understanding the visual constraints on lexical processing: New empirical and simulation results (Experiment 4)

Aaron Veldre, Lili Yu, Sally Andrews & Erik Reichle
It is well known that visual acuity is not uniform across the visual field. Acuity instead decreases precipitously from the center of vision. The region of maximum acuity, called the fovea, is comprised of the central 2º of the visual field, with a region of rapidly decreasing acuity called the parafovea extending an additional 5º of visual angle to either side of this. Although the photoreceptors required for perceiving fine detail are largely limited to...

1. Theory of Mind and emotion recognition in the Reading the Mind in the Eyes test: a factor analysis

Wendy Higgins, Vince Polito, Robert Ross & Robyn Langdon
3.1. Baron-Cohen and colleagues created The Reading the Mind in the Eyes Test (RMET, Baron-Cohen et al., 2001) as a test of theory of mind (ToM) ability in autistic adults. In experimental research, the RMET is now one of the most widely used tools to assess ToM in a variety of clinical and nonclinical populations. However, a limited understanding of the psychometric properties of the RMET, including its factor structure and its validity as a...

Sexual dimorphism in size and shape of the head in the sea snake Emydocephalus annulatus

Richard Shine & Claire Goiran
In snakes, divergence in head size between the sexes has been interpreted as an adaptation to intersexual niche divergence. By overcoming gape-limitation, a larger head enables snakes of one sex to ingest larger prey items. Under this hypothesis, we do not expect a species that consumes only tiny prey items to exhibit sex differences in relative head size, or to show empirical links between relative head size and fitness-relevant traits such as growth and fecundity....

Evolution of songbird eggs colour

Kiara L'Herpiniere
To understand why avian eggs are so variable in colour and patterning, we investigated contemporary species that provide insights into the evolutionary transitions that occurred during the early radiation of the songbirds. We quantified egg colour and patterning from museum collections of 269 species of Australian passerine and collated it to nest type data (cup or dome nesting species). Using phylogenetically reconstructed trait data, we showed that the ancestral passerine egg was likely to be...

Zebra finch song and distance call amplitude measurements: A transmission experiment and observational transects in the natural environment

Hugo Loning, Simon C. Griffith & Marc Naguib
Birdsong is typically seen as a long-range signal functioning in mate attraction and territory defense. Among birds, the zebra finch is the prime model organism in bioacoustics, yet almost exclusively studied in the lab. In the wild, however, zebra finch song differs strikingly from songbirds commonly studied in the wild as zebra finch males sing most after mating and in the absence of territoriality. Using data from the wild, we here provide an ecological context...

Understanding degraded speech leads to perceptual gating of a brainstem reflex in human listeners

Heivet Hernandez Perez, Jason Mikiel-Hunter, David McAlpine, Sumitrajit Dhar, Sriram Boothalingam, Jessica J.M. Monaghan & Catherine M. McMahon
The ability to navigate “cocktail-party” situations by focussing on sounds of interest over irrelevant, background sounds is often considered in terms of cortical mechanisms. However, subcortical circuits such as the pathway underlying the medial olivocochlear (MOC) reflex modulate the activity of the inner ear itself, supporting the extraction of salient features from auditory scene prior to any cortical processing. To understand the contribution of auditory subcortical nuclei and the cochlea in complex listening tasks, we...

Categorisation and the other-race effect

Daniel Guilbert
This experiment is designed to test social-cognitive explanations for the other-race effect in face recognition. In particular, this study tests whether categorisation of own-race faces reduces the other-race effect.

Investigating effects of semantic variables on word production

Leonie Lampe, Solène Hameau, Audrey Bürki, Nora Fieder, Paul Sowman & Lyndsey Nickels
This project investigates whether word production is affected by semantic variables. Specifically, we will simultaneously examine six feature-based semantic variables (number of near semantic neighbours, semantic similarity, number of semantic features, typicality, intercorrelational density, distinctiveness). This work will inform word production theory by (1) clarifying and dissociating effects of these semantic variables on word production; and (2) studying their temporal dynamics using EEG.

Loneliness and Interpersonal Emotion Regulation Effort

Kristina Mei, Katharine Greenaway, Ella Moeck & Hoang Tran
This study investigates interpersonal emotion regulation, which is the process by which people change others’ emotions (extrinsic) or their own emotions (intrinsic) through social means. We are interested in understanding how the amount of effort invested in interpersonal emotion regulation relates to loneliness in everyday life.

Rates of expansion of invasive cane toads in New South Wales

Richard Shine, Lincoln Mcgregor, Matthew Greenlees & Mark DeBruyn
Geographical variation in abiotic and biotic conditions can significantly affect the rate that an invasive species expands its range. The colonisation of Australia by cane toads (Rhinella marina) has attracted extensive research, but mostly in tropical regions rather than cooler climatic zones. We assembled multiple datasets to characterise the historical spread of toads at their southern (cool-climate) invasion front in north-eastern New South Wales (NSW). Perhaps because toads are relatively easy to find, visual and...

Development of orthographic expectations during spoken word training in second language learners

Vowel hyperarticulation in infant-directed speech – a meta-analysis

Irena Lovcevic, Titia Benders, Riccardo Fusaroli, Sho Tsuji & Christina Dideriksen
3.1. When addressing infants, adults produce a special speech register known as infant-directed speech (IDS) (Fernald & Simon, 1984), which can be differentiated from adult-directed speech (ADS) by a number of linguistic, acoustic, and visual properties (Chong, Werker, Russell, & Carroll, 2003; Cooper & Aslin, 1990; Fernald & Simon, 1984; Kalashnikova, Carignan, & Burnham, 2017; Kuhl et al., 1997). In this study, we are focused on one of these features, vowel hyperarticulation. Vowel hyperarticulation refers...

Abundance of lungworm parasites in invasive cane toads from burned and unburned sites

Richard Shine, Shannon Kaiser & Matthew Greenlees
The frequency and severity of wildfires are increasing due to anthropogenic modifications to habitats and to climate. Post-fire landscapes may advantage invasive species via multiple mechanisms, including changes to host-parasite interactions. We surveyed the incidence of endoparasitic lungworms (Rhabdias pseudosphaerocephala) in invasive cane toads (Rhinella marina) in near-coastal sites of eastern Australia, a year after extensive fires in this region. Both the prevalence of infection, and number of worms in infected toads, increased with toad...

Data from: Evaluating the foraging performance of individual honey bees in different environments with automated field RFID systems

Theotime Colin, Ryan J Warren, Stephen R Quarrell, Geoff R Allen & Andrew B Barron
Measuring the individual foraging performances of pollinators is crucial to guide environmental policies that aim at enhancing pollinator health and pollination services. Automated systems have been developed to track the activity of individual honey bees, but their deployment is extremely challenging. This has limited the assessment of individual foraging performances in full-strength bee colonies in the field. Most studies available to date have been constrained to use downsized bee colonies located in urban and suburban...

Orthographic facilitation of spoken word learning in noise

Andrea Salins, Linda Cupples, Greg Leigh & Anne Castles
It is well established that noisy environments compromise hearing and the ability to learn in children and adults (e.g., Klatte, Bergstrom, & Lachmann, 2013; Ljung, Sorqvist, Kjellberg, & Green, 2009). Researchers have shown that providing spellings during spoken word learning is beneficial for children with typical and atypical development. Further, this benefit has also been observed in second language learners. Providing spellings along with phonology may provide a more stable anchor than providing phonology alone,...
