Assessing Dexterity with Reaching Tasks
0 Views •
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.

Children who have complex communication needs can benefit from the use of a speech-generating device (SGD). Cognitive skills were identified as having an impact on the ability to navigate between levels of SGDs. This protocol describes the steps needed for Speech-language Pathologists to assess cognitive skills and navigational abilities.

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...

2014
This protocol describes the 5-choice serial reaction time task, which is an operant based task used to study attention and impulse control in rodents. Test day challenges, which are modifications of the standard task, increase flexibility of the task and can be combined with other manipulations to more fully characterize behavior.
FAQs
Latency to descend or fall provides a time-based outcome, whereas movement patterns and positional stability describe how the subject responds. Considering these measures together can distinguish a delayed response from an altered movement pattern or reduced ability to remain positioned. This multidimensional readout strengthens assessment of motor coordination, balance, and postural control.
Height and positioning conditions are important sources of experimental consistency. A defined elevation establishes a common challenge, while standardized placement reduces variation in the starting situation. Consistent conditions make differences in latency, movement patterns, or position maintenance more interpretable when comparing animals exposed to different disease, drug, or genetic conditions.
A single timing value may not capture the full behavioral response. Two subjects could show similar latency while displaying different movement patterns or differing abilities to maintain position. Recording these outcomes together provides a broader view of motor performance and helps identify whether an observed change concerns timing, coordination, balance, or postural control.
Investigators should define the elevation and positioning conditions before testing, place each animal in the same standardized manner, and record the prespecified behavioral outcomes. These include latency to descend or fall, observed movement patterns, and maintenance of position. Using the same recording approach supports objective comparisons across experimental conditions.
The assessment is useful when researchers need behavioral evidence of motor impairment associated with neurological injury, disease, drug exposure, or genetic alteration. It can be applied to compare motor function among experimental conditions and to examine whether performance changes as a disease progresses or after an intervention is evaluated.
Repeatedly examining standardized behavioral outcomes can provide objective measures for comparing motor function across relevant experimental conditions. Changes in latency, movement patterns, or position maintenance may indicate altered performance associated with disease or exposure. In preclinical studies, these measures help assess progression and evaluate treatment effects without relying on a single behavioral feature.
