In this video, we show a procedure to surgically isolate the corneoscleral button to generate an ex vivo porcine cornea model. The model is helpful for histological, pathological, and pharmacological studies due to its similarity to the human eye.

Piaget's Conservation Task and the Influence of Task Demands

2023
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...

Event-related Potentials During Target-response Tasks to Study Cognitive Processes of Upper Limb Use in Children with Unilateral Cerebral Palsy

Several children with unilateral Cerebral Palsy seem to disregard the preserved capacity of their affected upper limb. This Developmental Disregard is extensively described in the literature but the involved cognitive processes have not been studied. To study underlying cognitive factors of upper limb control, an event-related potential protocol was developed.

Learning and Memory: The Remember-Know Task
0 Views •
2023
Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Our experience of memory is varied and complex. Sometimes we remember events in vivid detail, while other times we may only have a vague sense of familiarity. Memory researchers have made a distinction between memories that are recollected versus those that are familiar. A recollected item is one that is not only remembered, but carries with it details of the time at which it was learned or encoded.
FAQs
Stimulus timing determines when a participant must detect and act on a target, while response rules specify whether to press or withhold the response. Changing either feature alters the cognitive and motor demands of a trial. Researchers can therefore examine whether performance changes reflect differences in attention, perception, decision-making, or motor control.
Reaction time indicates how quickly a participant responds, whereas errors show whether the response rule was followed accurately. Response consistency captures the stability of performance across trials. Examining these measures together helps distinguish speed from accuracy and shows whether an experimental condition affects reliable behavioral control rather than producing only an isolated fast or incorrect response.
A press-or-withhold design requires participants to identify the relevant stimulus and apply the correct response rule before acting. Performance therefore reflects more than the movement of pressing a button. Reaction time, errors, and consistency can indicate how attention, perception, decision-making, and motor control interact under defined experimental conditions.
Researchers need to define the stimulus timing, response instructions, target characteristics, and trial conditions consistently across the comparison being studied. These controls make it possible to attribute changes in reaction time, errors, or consistency to the experimental condition or cognitive demand rather than to unclear rules or shifting trial structure.
A typical procedure begins by giving participants instructions that specify when to press and when to withhold a response. The researcher then presents defined stimuli under controlled timing and trial conditions, while the participant responds using the designated button. The procedure records reaction time, accuracy-related errors, and consistency for later behavioral analysis.
Researchers can use the task when they need a direct behavioral measure of attention, perception, decision-making, motor control, or learning. Comparisons across experimental conditions can show how cognitive demands influence observable responses. The same measures may also help examine behavioral changes associated with neurological changes, provided the relevant conditions are carefully controlled.
