Object files can be purely episodic

Our ability to track an object as the same persisting entity over time and motion may primarily rely on spatiotemporal representations which encode some, but not all, of an object's features. Previous researchers using the 'object reviewing' paradigm have demonstrated that such representations can store featural information of well-learned stimuli such as letters and words at a highly abstract level. However, it is unknown whether these representations can also store purely episodic information (i.e. information obtained from a single, novel encounter) that does not correspond to pre-existing type-representations in long-term memory. Here, in an object-reviewing experiment with novel face images as stimuli, observers still produced reliable object-specific preview benefits in dynamic displays: a preview of a novel face on a specific object speeded the recognition of that particular face at a later point when it appeared again on the same object compared to when it reappeared on a different object (beyond display-wide priming), even when all objects moved to new positions in the intervening delay. This case study demonstrates that the mid-level visual representations which keep track of persisting identity over time--e.g. 'object files', in one popular framework can store not only abstract types from long-term memory, but also specific tokens from online visual experience.     

The Way It Is and the Way It Could Be: Fear,Lessness and the Quest for Fearless Dialogues™

“Fearless Dialogues? is the Civil Rights Movement of the 21st century,” says Dr. Bernard Lafayette, an original Freedom Rider and internationally renowned human rights activist. This article examines the history and philosophy of a burgeoning movement called Fearless Dialogues?, which seeks to alter the perspective of how we see and hear those who are perceived to be marginal. Drawing wisdom from a hard, heartfelt conversation documented in Ralph Ellison’s essay, “The Way It Is,” this interdisciplinary article utilizes resources from 20th and 21st century mystics to examine four primary fears that stifle dialogue and introduces an attitude of “lessness” that is necessary to create perspectival change.     

Educational–Occupational Mismatch,Race/Ethnicity,and Immigrant Wealth Attainment

This paper uses wealth attainment as an indicator of economic integration and assesses how educational–occupational mismatch (i.e., over/underqualification) and race/ethnicity affect the wealth attainment of a sample of legal permanent residents in the USA. Using data from the New Immigrant Survey, this paper finds that overqualification is positively associated with wealth attainment, but below the rate for adequately qualified workers in the same occupation. Underqualified immigrants are associated with a pattern of wealth attainment that is equivalent to the adequately qualified. Racial/ethnic wealth inequality among legal permanent residents generally reflects the well-documented pattern among the U.S. native-born. This paper concludes with a discussion that places these results alongside previous research that examines the relationship between educational–occupational mismatch and income among immigrants.     

Improving the Efficacy of Security Screening Tasks: A Review of Visual Search Challenges and Ways to Mitigate Their Adverse Effects

Security checkpoints are used to keep potentially dangerous items and individuals out of secure areas. Although technological advances can enhance security efficacy through both accuracy and speed, ultimate success or failure is largely determined by human performance. As such, it is necessary to minimize any shortcomings that stem from the limits of human cognitive abilities. Cognitive performance can be influenced by numerous factors, including those imposed by the search task (e.g., the number of prohibited items) and the basic abilities of the searchers themselves (e.g., competency and experience). Here, we review and discuss four specific challenges of the task itself that can negatively affect the accuracy of a security screening: target visibility, an unknown target set, the possible presence of multiple targets, and low target prevalence. For each, we present the challenge faced and the potential significance of the challenge and then offer possible solutions on the basis of the existing literature.

Metaphor in intergroup relations

Belonging to groups and relating to other groups are central parts of our lives, but they confront us with abstract ideas (e.g., identity and power) and nebulous feelings. To make sense of it all, people rely on conceptual metaphors: cognitive tools that ground abstractions in dissimilar, more concrete ideas that are easier to grasp. We review some common metaphors that people use in intergroup contexts—metaphors that draw on knowledge of such familiar experiences as physical cleansing and warmth sensations. We review evidence that these metaphors are not mere figures of speech, but have a systematic and practically important influence on intergroup attitudes and behavior. Most of this work shows that reliance on metaphor contributes to prejudice, stereotyping, and discrimination, sometimes without the person's awareness. Yet we consider the hopeful possibility that citizens, politicians, and researchers can harness the power of metaphor to promote intergroup harmony and peace.     

Theology and Interpretation: The Case of Aquinas and Calvin on Romans

This article explores how Aquinas's and Calvin's theology of justification, the law and the nature of human works integrate with their interpretations of Romans by analyzing their commentaries on 1:16b–17, focusing on the iustitia Dei, and 2:13, which addresses the relationship between works and justification. Aquinas's interpretation unfolds by emphasizing the work of Christ in and through sinners, while Calvin's interpretation emphasizes the work of Christ for and to sinners. I also demonstrate how the theological judgements embedded in these sections inform their reading of Romans as a whole.     

Cognitive pitfall! Videogame players are not immune to dual-task costs

With modern technological advances, we often find ourselves dividing our attention between multiple tasks. While this may seem a productive way to live, our attentional capacity is limited, and this yields costs in one or more of the many tasks that we try to do. Some people believe that they are immune to the costs of multitasking and commonly engage in potentially dangerous behavior, such as driving while talking on the phone. But are some groups of individuals indeed immune to dual-task costs? This study examines whether avid action videogame players, who have been shown to have heightened attentional capacities, are particularly adept multitaskers. Participants completed three visually demanding experimental paradigms (a driving videogame, a multiple-object-tracking task, and a visual search), with and without answering unrelated questions via a speakerphone (i.e., with and without a dual-task component). All of the participants, videogame players and nonvideogame players alike, performed worse while engaging in the additional dual task for all three paradigms. This suggests that extensive videogame experience may not offer immunity from dual-task costs.
