The production of pantomime is a sensible task to detect praxis deficits. It is usually assessed by presenting objects visually or by verbal command. Verbal instructions are given either by providing the name of the object (e.g., "Show me how to use a pen") or by requiring the object function (e.g., "Show me how to write"). These modes of testing are used interchangeably. The aim of this study is to investigate whether the different instructions generate different performances. Fifty-one healthy participants (17-89 years old) were assessed on three pantomime production tasks differing for the instruction given: two with verbal instructions (Pantomime by Name and Pantomime by Function) and one with the object visually presented (Pantomime by Object). Results showed that Pantomime by Function produced the poorest performance and the highest frequency of Body Parts as Tool (BPT) errors, suggesting that the way the instructions are given may determine the performance in a task. Nuances in test instructions could result in misleading outcome.

In the present study, we used an item-method directed-forgetting paradigm to test whether instructions to forget or remember one item affect memory for subsequently studied items. In two experiments (...
An astonishing aspect of human cognitive flexibility concerns the ability to efficiently convert complex symbolic instructions into novel behaviors. In such ability, the rapid transformation of releva...
Most studies investigating the influence of primes on the processing of subsequent targets involve a main task in which responses are made to the targets, and a task that tests prime awareness. If the...
Instructions in sports are used to improve athletes' performance. However, instructions can also impair performance if they direct athletes' attention to a to-be-avoided behavior which paradoxically p...
The aim of this study was to investigate the effects of task complexity on the motor learning of by stroke survivors. Participants (N = 24) performed 150 trials of a simple or complex balance task d...
This study evaluates the effect of different modalities of dual-task training in the improvement of gait biomechanics, postural balance, falls episodes, executive functioning and quality o...
The child will complete computerized tasks and paper-pencil test, and will be presented with symbols, letters, or numbers on a computer screen and asked to respond by pressing a button on ...
The study aims to examine the effect of single-task, dual-task and analogy training during gait rehabilitation on conscious motor processing propensity, balance, walking ability and fear o...

The goal of the study is to show the concordance between the dual-task test achieved usually on an electronic treadmill and the dual-task test achieved with a cyclo-ergometer.
Timed test in which the subject must read a list of words or identify colors presented with varying instructions and different degrees of distraction. (Campbell's Psychiatric Dictionary. 8th ed.)
Set of instructions about how to prepare food for eating using specific instructions.
The observation and analysis of movements in a task with an emphasis on the amount of time required to perform the task.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
A projective test used to evaluate a broad range of personality variables including pathology of thought and perception. The subject's responses to inkblot prints are scored along with subjective interpretation by the test administrator.
