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...

Assessing Dexterity with Reaching Tasks

Reaching tasks are employed in behavioral neuroscience to investigate motor learning and forelimb dexterity. Much like human hands, rodents have dexterous forepaws, which are necessary for executing coordinated and precise motor movements. Experimenters may utilize food rewards to train rodents to reach and for testing their reaching abilities. These tasks help behavioral neuroscientist in understanding how CNS injuries, such as a stroke, may impair reaching ability and dexterity in humans.

The murine model of irreversible unilateral ureteric obstruction (UUO) is presented together with the model of reversible UUO in which the ureteric obstruction is relieved by anastomosis of the severed ureter into the bladder. These models enable the study of renal inflammation and scarring as well as tissue remodeling.

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...
FAQs
Performance depends on coordinating several responses rather than simply moving toward the goal. The individual must inhibit its first approach, detect that direct access is blocked, and shift toward an alternative route. This sequence makes the task useful for examining how behavioral control and problem solving operate when an expected path no longer produces access.
Visual information can indicate where the goal remains located, while spatial information helps the individual organize movement around the barrier. Effective detour behavior therefore requires selecting a route that preserves access despite obstruction. Differences in route choice may reveal how individuals use these cues to guide movement during problem-solving behavior.
The visible goal can continue to encourage a direct approach even after the barrier makes that response ineffective. Inhibiting this initial tendency allows the individual to disengage from the blocked path and consider another option. Researchers can therefore use task performance to examine whether changes in behavioral control affect adaptation to blocked access.
Completion time, errors, and route choice provide complementary measures of performance. Time can indicate how quickly the individual adapts, errors can reflect unsuccessful responses to the obstruction, and route choice can show how it solves the access problem. Considering these measures together gives a broader picture than relying on task completion alone.
The same behavioral challenge can be examined across different species or experimental conditions, with performance differences interpreted through completion time, errors, and selected routes. Such comparisons can help identify variation in problem solving, inhibitory control, spatial reasoning, or cognitive flexibility. The design also supports examination of how experience, development, or neurological function relates to performance.
Variation in task outcomes may reflect more than problem-solving ability alone. Motivation can influence how readily an individual persists, while experience and development may affect adaptation, route selection, and control of the initial approach. Researchers can examine these factors by comparing differences in completion time, errors, and behavior across relevant groups or experimental conditions.
