Age differences in visual statistical learning

Recent work has shown that older adults' lessened inhibitory control leads them to inadvertently bind co-occurring targets and distractors. Although this hyper-binding effect may lead to the formation of more superfluous associations, and thus greater interference at retrieval for older adults, it may also lead to a greater knowledge of information contained within the periphery of awareness. On the basis of evidence that younger adults only show learning for statistical regularities contained within attended information, we asked whether older adults may also show learning for regularities contained within to-be-ignored information. Older and younger adults viewed a series of red and green pictures and performed a 1-back task on one of the colors. Unbeknownst to participants, both color streams were organized into triplets that occurred sequentially. Implicit memory for the triplets from both the attended and ignored streams was tested using a speeded detection task. Replicating previous work, younger adults demonstrated more learning for the attended triplets than the unattended triplets. Older adults, however, demonstrated similar learning for both the attended and ignored triplets, suggesting that contrary to popular belief, they may actually know more than younger adults about the world around them, including how seemingly irrelevant events co-occur.

Conditionals and inferential connections: toward a new semantics*

Abstract

In previous published research (“Conditionals and Inferential Connections: A Hypothetical Inferential Theory,” Cognitive Psychology, 2018), we investigated experimentally what role the presence and strength of an inferential connection between a conditional’s antecedent and consequent plays in how people process that conditional. Our analysis showed the strength of that connection to be strongly predictive of whether participants evaluated the conditional as true, false, or neither true nor false. In this article, we re-analyse the data from our previous research, now focussing on the semantics of conditionals rather than on how they are processed. Specifically, we use those data to compare the main extant semantics with each other and with inferentialism, a semantics according to which the truth of a conditional requires the presence of an inferential connection between the conditional’s component parts.     

Trauma is not the whole story: Trajectories of responses to childhood disasters intertwining with Life following the Indian Ocean tsunami

In an era of global threats, understanding the implications of disasters on young people's life course is of central importance. A particular emphasis should be placed on non-Western economically developing societies that are considered as vulnerable and are less studied, and on social groups within these societies that are underrepresented. The present study focuses on young Sri Lankan women who experienced the 2004 Indian Ocean tsunami as children. Thirteen young women generated their life stories in semi-structured interviews, 12 years after the disaster had elapsed. Holistic narrative analysis revealed new variations and in-depth meanings in disaster response trajectories and presented the intertwining courses of the responses to the Potentially Traumatic Event (PTE) with ecological aspects throughout development, as in Trajectories intertwining with Life (TiL). This study provides empirical, methodological, conceptual and practical innovations to the study of human development throughout the life course, within the interdisciplinary fields of trauma and disasters.

Highlights

• This research is interested in how childhood disaster response trajectories among an understudied population are understood through an ecological-developmental perspective.
• Life stories uncover Trajectories intertwining with Life (TiL) among Sri Lankan women who were children during the Indian Ocean tsunami.
• The TiL unique outcomes, integrating trauma responses as inseparable from ecological and developmental aspects, offer various theoretical and applied implications.
