Does exercise lead to integration of two tasks?

Supervisor: prof.dr. Willem Verwey

A series of studies with the Discrete Sequence Production (DSP) tasks showed that people learn and automate a movement sequence by developing motor representations called motor chunks (for an overview, see Abrahamse et al., 2013). It is not clear to what extent some task can be integrated with a practiced keying task. To determine this, an experiment will be performed in which participants, while learning a keying sequence, will also hear a high or low tone at a fixed location. They are instructed to count the number of low tones. The question is whether performance of the keying sequence will deteriorate if the tones are presented at another time during sequence execution.

Selecting a movement pattern

Supervisor: prof.dr. Willem Verwey

Previous research has shown that the selection of a response takes place on the basis of the expected feedback. This, however, has not yet been investigated for movement patterns. The aim of this research project is to have participants learn movement patterns that are associated with a particular feedback (i.e., an action-effect). Subsequently, we will examine whether the selection of the movement pattern is disturbed if the movement pattern is preceded by another action-effect.

The effect of an unexpected stimulus on the performance of a learned key press sequence

Supervisor: prof.dr. Willem Verwey

A series of studies with the Discrete Sequence Production (DSP) tasks showed that people learn and automate a movement sequence by developing motor representations called motor chunks (for an overview, see Abrahamse et al., 2013). Basically, these chunks make the use of key-specific stimuli after the first unnecessary. However, it is not clear to what extent these stimuli are still being used after practice. To investigate this, participants will first learn two key press sequences. In the test phase, the stimuli will sometimes be displayed at an unexpected moment, and the effects of this manipulation will be assessed.
