Exam 15: Attention and Higher Cognition

Reflexive attention is

The _______ component of the ERP waveform is associated with higher-order auditory stimulus processing and late attentional selection.

The overall level of alertness of an individual is called _______, as distinguished from the process by which we select and focus on one or more stimuli, which is called _______.

Auditory attention produces an enhancement of the _______ ERP component, whereas visual attention produces enhancement of the _______ component.

Hemispatial neglect may lead to a person's inability to notice stimuli on one half of the body, even if both halves have been stimulated simultaneously. This phenomenon is referred to as

A patient is shown a hammer and a wrench but can only attend to and identify one of these objects at a time. This condition is called _______ and is associated with _______.

An fMRI of a person sitting staring out the window deep in thought and introspection would show activation of a circuit of brain regions called the _______ network.

What are the benefits of recording event-related potentials? Detail the specific components of ERPs and the information they provide about attentional processes.

What are ERPs and why are they essential for the study the neural basis of attention?

Discuss inattentional blindness. Explain how this type of "blindness" fits into the model of selective attention and give an example of a divided attention task in which such blindness may manifest.

In the shadowing experiment, subjects are presented simultaneously with different stimuli to each ear and asked to focus their attention only on one ear. The result is that subjects are unable to report much about the content in the unattended ear. Which form of attentional processing accounts for this difficulty?

In early-selection models of attention, when is information filtered out?

You are looking for your friend at a hockey game. She is easy to find as she is wearing a purple sweater, while everyone else is wearing blue and white. Your behavior is an example of a

Male frogs seeking mates vocalize among birds, insects, and the chorus of other species of frogs. That females are able to locate male frogs of their species among all the ambient noise provides an example of the _______ effect.

In humans, the _______ occupies the posterior quarter of the _______ and is involved in the orienting and shifting of attention.

You are talking to a friend while waiting for a bus, and while you converse you are also aware of passing vehicles so you are sure not to miss your bus. Which structure is responsible for filtering out distracting stimuli while you talk to your friend and wait for the bus?

Explain the voluntary and reflexive versions of the symbolic cuing task, and describe how they are related to early- and late-selection attentional models.

During ERPs in which the subject's attention is directed to find a particular target in an array and ignore distracters, a_______ is triggered at occipitotemporal sites contralateral to the visual target.

Patients with _______ lobe lesions struggle with task shifting and tend to _______ (continue beyond a reasonable degree in any activity).

Which research finding is inconsistent with the notion of free will?
