Understanding other peoples actions: intention and attention.

This study investigated the extent to which observation of an action performed by a human actor or a robotic arm may kinematically prime the performance of an observer subsequently required to perform a similar action. In Experiment 1, an actor reached ...

Failures of retrieval and comparison constrain change detection in natural scenes.

In a change detection paradigm, a target object in a natural scene either rotated in depth, was replaced by another object token, or remained the same. Change detection performance was reliably higher when a target postcue allowed participants to ...

Change deafness: the inability to detect changes between two voices.

A shadowing task was used to demonstrate an auditory analogue of change blindness (the failure to detect a change in a visual scene), namely change deafness. Participants repeated words varying in lexical difficulty. Halfway through the word list, either ...

Phase attraction in sensorimotor synchronization with auditory sequences: effects of single and periodic distractors on synchronization accuracy.

Four experiments showed that both single and periodic distractor tones affected the timing of finger taps produced in synchrony with an isochronous auditory target sequence. Single distractors had only small effects, but periodic distractors occurring at ...

Vanishing dual-task interference after practice: has the bottleneck been eliminated or is it merely latent?

Practice can, in some cases, largely eliminate measured dual-task interference. Does this absence of interference indicate the absence of a processing bottleneck (defined as an inability to carry out certain stages in parallel)? The authors show that a ...

Postrecognition of interleaved melodies as an indirect measure of auditory stream formation.

Primitive processes involved in auditory stream formation are measured with indirect, objective method. A target melody interleaved with a distractor sequence is followed by a probe melody that was identical to the target or differed by 2 notes. ...

Convergence of different versions of the continuous performance test: clinical and scientific implications.

The Continuous Performance Test has been used for the last 40 years to measure sustained attention or vigilance in many different populations. Different versions of the test have been developed, but little is known about how similar these tests are, and ...

Attending to the distractor and old/new discriminations in negative priming.

When participants ignore an irrelevant distractor they typically show impaired responding to that item if it becomes the relevant stimulus on a subsequent trial. In Experiment 1 (N = 64), a masked white colour name was presented briefly before a Stroop ...

Changing your mind: on the contributions of top-down and bottom-up guidance in visual search for feature singletons.

Observers, searching for targets among distractor items, guide attention with a mix of top-down information--based on observers knowledge--and bottom-up information--stimulus-based and largely independent of that knowledge. There are 2 types of top-down ...

Graspable objects grab attention when the potential for action is recognized.

Visually guided grasping movements require a rapid transformation of visual representations into object-specific motor programs. Here we report that graspable objects may facilitate these visuomotor transformations by automatically grabbing visual ...
