Amount of Mental Practice and Performance of a Simple Motor Task

The level of aspiration and performance was examined for 25 male psychiatric inpatients whose mean age was 57.4 yr. and mean length of hospitalization was 23–6 yr. For a simple motor task involving flipping a plastic chip over a goal line, each patient expressed the ward and his personal pretask levels of aspiration, performed the task, and expressed his personal posttask aspiration. The expressions of both the ward and pretask levels of aspiration were less than the mean score of a nonhospitalized referent group. Both performance and posttask levels of aspiration were greater than the pretask level. More patients predicted they would perform worse than the other patients on the ward than predicted they would perform better. The patients appropriately shifted their levels of aspiration either up after success or down after failure. The results were discussed according to expectations from classical theory as well as findings with schizophrenics. Implications for further research were discussed.

The Difference

After prolonged practice (1300 10-sec trials) the tapping speed of the nonpreferred hand reached that of the preferred hand on a simple finger-tapping task. Analysis of the intertap intervals showed the variability of the duration of intertap intervals was smaller for the preferred than for the nonpreferred hand; the difference was not affected by the prolonged practice for N = 1.

Illustrative Application

Recent advances in neuroimaging techniques have provided precise spatial localization of brain activation applied in several neuroscience subareas. The development of functional magnetic resonance imaging (fMRI), based on the BOLD signal, is one of the most popular techniques related to the detection of neuronal activation. However, understanding the interactions between several neuronal modules is also an important task, providing a better comprehension about brain dynamics. Nevertheless, most connectivity studies in fMRI are based on a simple correlation analysis, which is only an association measure and does not provide the direction of information flow between brain areas. Other proposed methods like structural equation modeling (SEM) seem to be attractive alternatives. However, this approach assumes prior information about the causality direction and stationarity conditions, which may not be satisfied in fMRI experiments. Generally, the fMRI experiments are related to an activation task; hence, the stimulus conditions should also be included in the model. In this paper, we suggest an intervention analysis, which includes stimulus condition, allowing a nonstationary modeling. Furthermore, an illustrative application to real fMRI dataset from a simple motor task is presented.

Definition Of

To examine the type of proprioceptive information which subjects include in the definition of tension, 52 subjects were asked to indicate the location of where they felt tension while engaging in a simple motor task. Responses indicated that tendon stretch, muscle tension, and other cues are utilized in the subject's definition of tension.
