Is there a general task switching ability?

Participants were tested on two analogous task switching paradigms involving Shape/Size tasks and Vertical/Horizontal tasks, respectively, and three measures of psychometric intelligence, tapping fluid, crystallized and perceptual speed abilities. The paradigms produced similar patterns of group mean reaction times (RTs) and the vast majority of the participants showed switching cost (switch RT...

The role of prefrontal cortex and posterior parietal cortex in task switching.

Human ability to switch from one cognitive task to another involves both endogenous preparation without an external stimulus and exogenous adjustment in response to the external stimulus. In an event-related functional MRI study, participants performed pairs of two tasks that are either the same (task repetition) or different (task switch) from each other. On half of the trials, foreknowledge a...

The anodal tDCS over the left posterior parietal cortex enhances attention toward a focus word in a sentence

The posterior parietal cortex (PPC) has two attentional functions: top-down attentional control and stimulus-driven attentional processing. Using the focused version of the reading span test (RST), in which the target word to be remembered is the critical word for comprehending a sentence (focused word) or a non-focused word, we examined the effect of tDCS on resolution of distractor interferen...

Voluntary facial expression and hemispheric asymmetry over the frontal cortex.

Brain activity was monitored while 36 participants produced facial configurations denoting anger, disgust, fear, joy, and sadness. EEG alpha power was analyzed during each facial pose, with facial conditions grouped according to the approach/withdrawal motivational model of emotion. This model suggests that "approach" emotions are associated with relatively greater left frontal brain activity w...

Measuring task-switching ability in the Implicit Association Test.

Recently, the role of method-specific variance in the Implicit Association Test (IAT) was examined (McFarland & Crouch, 2002; Mierke & Klauer, 2003). This article presents a new content-unspecific control task for the assessment of task-switching ability within the IAT methodology. Study 1 showed that this task exhibited good internal consistency and stability. Studies 2-4 examined method-speci...
