Marginal Dishonesty: The Adding-to-10 Task

Source: Julian Wills & Jay Van Bavel—New York University Classical economic theory asserts that people are rational and self-interested. In addition to seeking wealth and status, people are motivated by other goals. As a result, financial motives can sometimes be dwarfed by other internal needs, such as maintaining a positive self-concept or affiliating with other group members. Ethical dilemmas, such as the temptation to cheat on taxes, can result when these motives are in conflict. On...

Source: Laboratories of Judith Danovitch and Nicholaus Noles—University of Louisville Jean Piaget was a pioneer in the field of developmental psychology, and his theory of cognitive development is one of the most well-known psychological theories. At the heart of Piaget’s theory is the idea that children’s ways of thinking change over the course of childhood. Piaget provided evidence for these changes by comparing how children of different ages responded to questions and problems that he...

2025
The video outlines a process for creating genetically modified CAR T cells through the CRISPR-Cas9 System. Infecting T cells with CRISPR and CAR lentiviruses results in modifications to the target gene and the synthesis of a chimeric antigen receptor or CAR, ultimately leading to the formation of genetically modified CAR T cells.

This video demonstrates a technique for generating antigen-specific chimeric antigen receptor (CAR) T cells through retroviral transduction. Activated murine CD8+ T cells are added to a microwell plate coated with recombinant fibronectin fragments. Retroviral vectors containing transgenic RNA encoding an antigen-specific chimeric antigen receptor (CAR) are then introduced, and the plate is centrifuged to facilitate transduction. After incubation, the transduced cells express antigen-specific...

The lymphodepletive and immunomodulatory effects of chemotherapy and radiation standard of care can be leveraged to enhance the antitumor efficacy of T cell immunotherapy. We outline a method for generating EGFRvIII-specific chimeric antigen receptor (CAR) T cells and administering them in the context of glioblastoma standard of care.
FAQs
Maintaining a stable relationship with the lead vehicle requires continuous adjustments rather than a single reaction. When the lead vehicle accelerates or decelerates, the participant changes acceleration or braking to manage speed and headway. Researchers can then examine how consistently control is preserved as traffic conditions change, making the task sensitive to alterations in attention and response.
Reaction time, speed variability, time to collision, and braking behavior capture different aspects of driver performance. Reaction time reflects how quickly a participant responds, while speed variability shows how consistently speed is regulated. Time to collision and braking behavior add information about responses to changing traffic conditions, allowing researchers to examine effects on control and attention.
Headway and braking behavior show how participants manage distance and speed when the lead vehicle changes its movement. Differences in these responses can indicate how individuals perceive and respond to changing driving conditions. Researchers may therefore compare these measures across participants or conditions to study the effects of stress, fatigue, drugs, distraction, or individual differences in risk perception.
A participant completes the task in a driving simulator or an instrumented vehicle while responding to programmed changes in the lead vehicle’s speed. The study records how the participant adjusts acceleration and braking while maintaining the driving scenario. Researchers then evaluate measures such as reaction time, speed variability, time to collision, and braking behavior.
Researchers use the task when they need a standardized way to examine driving performance and attention under changing traffic conditions. It can support investigations of distraction, fatigue, drugs, stress, and individual differences in risk perception. Because the task produces measurable responses, it also helps compare driver behavior across experimental conditions.
The task provides behavioral measures that can help characterize how drivers respond to changes in speed, following distance, and braking demands. Those observations are relevant to human factors research and the study of vehicle-assistance systems. By examining control, attention, and response patterns, researchers can evaluate driver behavior within contexts involving traffic safety and vehicle support technologies.
