Visually guided foraging in virtual worlds: Domain-general properties of search behavior.

Sarah K. Salo, Alastair D. Smith

Everyday human behavior involves economically driven search for visually relevant targets in complex three-dimensional environments. However, psychological research has typically examined visual search and foraging mechanisms separately, with insights into search emphasizing attentional efficiency and accounts of foraging highlighting decision making and …

Navigating Knowledge: Effects of State-Induced Curiosity on Children's Word Learning and Search Strategies.

Anna Caunt, Shaun Dordoy, Rana Abu‐Zhaya, Alastair D. Smith

Early learning takes place within complex, multimodal environments where curiosity plays a critical role in guiding exploratory behaviors and supporting cognitive development. While trait curiosity shapes children's early learning experiences, state curiosity is context-dependent fostering early learning, in-part, through information seeking behaviors. …

A timely warning: Clock drawing errors in young adults and the long-term validity of cognitive screens

Alastair D. Smith, Sarah K. Salo

Objective: The clock drawing test (CDT) assesses multiple cognitive functions, including visuospatial construction and executive planning, and it is a core feature of many cognitive screens. Recent evidence indicates that young adults may experience difficulties producing an accurate response and we present …

Probability cueing in large-scale environmental search: The role of landmark cues in statistical learning.

Shaun Dordoy, Rory Baxter, Alastair D. Smith

Efficient environmental search is an important and adaptive everyday skill. A particular feature of theoretical interest is whether large-scale search is informed by the spatial statistics of the environment-probability cueing is a robust effect in two-dimensional visual search tasks, but studies of …

Unreliable landmarks disrupt egocentric navigation in desktop virtual environments.

Rory Baxter, Alastair D. Smith

Navigation relies on the integration of both allocentric (world-centered) and egocentric (navigator-centered) spatial cues. An influential real-world navigational task dissociated allocentric place learning from egocentric path integration, highlighting the decline in allocentric cue use associated with cognitive aging. This report describes a …

Characterising the inconsistency between perceived and actual sleep and its impact upon cognition and mood

Hannah Windmill, Alastair D. Smith, Matthew E. Roser, Ashwin Dhanda et autres

Sleep profoundly influences human behaviour across cognition, affect, and daily experience. This study evaluated how subjective reports and objective measures of sleep capture the interaction between sleep quality and quantity on cognition and affect. We collected subjective sleep reports using the Pittsburgh …

Characterising the anxiogenic network from functional connectivity analysis of the CO2 challenge model

Daniel Graham, Jonathan F. Marsden, Alastair D. Smith, Gary R. Smerdon et autres

The CO 2 challenge model (CCM) is a gas inhalation paradigm that provides precisely controlled anxiety induction in experimental settings. Despite its potential as an experimental model of anxiety, our understanding of the neural effects of the CCM is incomplete. This study …
