Psychophysics is essential for studying perception phenomena through sensory information. Here we present a protocol to perform a two-interval forced-choice task as implemented in a previous report on human psychophysics where participants estimated the duration of visual, auditory, or audiovisual intervals of aperiodic trains of pulses.

The goal of this protocol is to measure the center of pressure (COP) replacement using a high spatial resolution sensor sheet to reflect the spatial stability in a precision grip. The use of this protocol could contribute to greater understanding of the physiology and pathophysiology of grasping.

Piaget's Conservation Task and the Influence of Task Demands

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

2023
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.
FAQs
Force magnitude indicates how much pressure an individual can generate, whereas timing measures when force is produced and adjusted. Changes across trials add information about consistency and performance shifts over time. Examining these measures together helps separate aspects of strength from broader motor control, coordination, or learning-related changes.
Force regulation reflects the ability to adjust pressure rather than simply produce a single maximal output. Researchers can examine changes in applied force across repeated trials to evaluate control and consistency. This distinction is important because an individual may generate force yet show altered regulation, coordination, or adaptation during the task.
Timing shows how force production unfolds during the behavioral trial, complementing the recorded force magnitude. Differences in when pressure is applied or changed can provide evidence about motor coordination and control. Together, temporal and force-related measurements offer a more complete view of sensorimotor performance than either measure considered alone.
The basic setup uses a force-sensitive handle or bar that a participant or animal can grip. The individual applies pressure while the device records force magnitude, timing, and changes across trials. This arrangement produces quantitative behavioral data that researchers can examine for performance differences, repeated-trial changes, and treatment-related effects.
Researchers apply the task when they need objective measures of hand or forelimb motor performance. It can support studies of strength, coordination, motor control, learning, neurological injury, and experimental treatments. Because the same force-related outcomes can be collected across trials, the method is useful for evaluating changes in sensorimotor behavior.
The recorded behavioral measures provide a quantitative index of how force is generated and regulated. In behavior research, these outcomes can be related to sensorimotor function and to changes associated with neurological injury or experimental intervention. The data therefore help investigators study observable motor performance while considering the neural mechanisms that support force generation and regulation.
