The present study investigated interactions between iconic memory and long-term memory during visual search. The contextual cueing paradigm was combined with a brief presentation procedure to determine whether statistical learning takes place from flashed displays and acts as a cue to guide spatial attention within iconic memory in subsequent visual search. In five experiments, participants were exposed to search displays that were presented for only 50 ms and had to detect a target among 11 distractors. Half of those displays were repeated across the task and half were presented once. The results revealed a contextual cueing effect in four of the experiments, revealing the capacity of the human brain to extract spatial regularities from very brief visual presentations and to later activate this knowledge to guide attention within a representation briefly maintained within iconic memory.

Iconicity is a relationship of resemblance between the form and meaning of a sign. Compelling evidence from diverse areas of the cognitive sciences suggests that iconicity plays a pivotal role in the processing, memory, learning, and evolution of both spoken and signed language, indicating that iconicity is a general property of language. However, the language-specific aspect of iconicity, illustrated by the fact that the meanings of ideophones in an unfamiliar language are hard to guess (e.

This article explores the concept of transgenerational trauma. I draw from two distinct archives to approach the "transgenerational" in a more nuanced manner - one that moves beyond a linear past-to-present trajectory. The first of these is the Freudian archive, where I revisit the concept of to shed light on the temporal dynamics between past and present, particularly in the affective responses of young black students during interactions with their white peers.

The phenomenon of near-death experience (NDE) is attracting a growing attention among researchers of various fields. In this study, we looked at NDE from a cognitive perspective to find out how NDE events are embodied when people recall and describe them. We examined the descriptions of a group of people talking about what they had experienced in the state of NDE.

In the present study, an attempt was made to replicate results found about the influence of valence on prioritisation and decay in iconic memory. Hereby, the evaluative conditioning effect was used to induce valence for formerly neutral stimuli. The effect is gained by pairing neutral stimuli with either positive, negative, or neutral images in a conditioning phase.

Background: Assistive technology is becoming increasingly accessible and affordable for supporting people with dementia and their care partners living at home, with strong potential for technology-based prompting to assist with initiation and tracking of complex, multistep activities of daily living. However, there is limited direct comparison of different prompt features to guide optimal technology design.
Objective: Across 3 experiments, we investigated the features of tablet-based prompts that best support people with dementia to complete activities of daily living at home, measuring prompt effectiveness and gaining feedback from people with dementia and their care partners about their experiences.
