Implicit Motor Learning after Unilateral Stroke Using Serial Reaction Time Task

The serial reaction time task: implicit motor skill learning?

Since its development 20 years ago, the serial reaction time task (SRTT) has gone from being a tool used by psychologists (Nissen and Bullemer, 1987) to one that, in the last few years, has been embraced by a wider community (Fig. 1). Embedded within this task is a sequence, a connected series of events, that engages processes supporting the temporal organization of behavior, the formation of h...

Implicit and Explicit Knowledge in the Serial Reaction Time Task

Motor learning of a dynamic balancing task after stroke: implicit implications for stroke rehabilitation.

BACKGROUND AND PURPOSE After a stroke, people often attempt to consciously control their motor actions, which, paradoxically, disrupts optimal performance. A learning strategy that minimizes the accrual of explicit knowledge may circumvent attempts to consciously control motor actions, thereby resulting in better performance. The purpose of this study was to examine the implicit learning of a d...

Motor learning by observation: evidence from a serial reaction time task.

This study sought evidence of observational motor learning, a type of learning in which observation of the skilled performance of another person not only facilitates motor skill acquisition but does so by contributing to the formation of effector-specific motor representations. Previous research has indicated that observation of skilled performance engages cognitive processes similar to those o...

Stimulus-dependent modulation of perceptual and motor learning in a serial reaction time task

In two experiments, we investigated the impact of spatial attributes on the representation acquired during a serial reaction time task. Two sequences were used, in which structural regularities occurred either in the horizontal or in the vertical locations of successive stimuli. After training with the dominant hand, participants were required to respond with the non-dominant hand to either the...

Implicit learning of a perceptual-motor skill after stroke.

BACKGROUND AND PURPOSE A motor skill can be learned implicitly, without awareness of what is being learned. The purpose of this study was to examine the ability of adults who had unilateral stroke to learn implicitly a perceptual-motor task. SUBJECTS Subjects were 47 people who were poststroke and 36 control subjects. METHODS Participants performed sequences of hand movements in response to...
