The audience effect causes people to change their behavior in the presence of another person. It can lead to better motor performance and greater generosity. Both human entities and invisible characters can induce this effect in young children and adults. In this study, we examined whether children’s imaginary companions can induce this effect. Accordingly, 49 children, aged 4 to 6 years, who had personified objects were subjected to a simple motor task (dropping marbles as fast as possible within 2 minutes) and moral task (deciding how many stickers to take from anonymous children) across three conditions: alone, in the presence of a human adult, and personified object, respectively. Performance on the simple motor task did not differ across conditions. However, children took more stickers in the presence of their personified objects than in the human conditions. These results are discussed in relation to children’s recognition of their personified objects.

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.

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.

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.
