EDA can distinguish between positive and negative emotions

Two basic methods for the measurement of EDA are the recording of [blank_start]skin conductance[blank_end] (SC) and [blank_start]skin potential[blank_end] (SP).

Spontaneous EDA refers to:

The outer layer of the skin is the:

The total number of sweat gland is:

Sweating is only thermoregulatory.

Stabiles are the people who are ____________ the median of SPR production while labiles are the people ___________.

A study showed that SCL and SCRs were [blank_start]significantly higher[blank_end] when signals came at fixed intervals than when they were variable.

The RTs to critical signals were found to be [blank_start]significantly faster[blank_end] for the high-arousal as compared to the low-arousal group.

It appears that faster RTs are associated with lower SCL.

When studying easy, moderately difficult, and difficult learning materials, SCLs and SCRs were significantly higher during the learning of:

Studies of EDA and verbal learning indicate that more successful learning, in general, tends to be associated with [blank_start]greater[blank_end] amounts of EDA. The higher levels of EDA are associated with [blank_start]increased[blank_end] alertness and effort when individuals are involved in the acquisition of [blank_start]novel[blank_end] materials. This same process is implicated in respect to SCL in short-term memory tasks. Moreover, threat-related stimuli have been found to produce larger numbers of SCRs, higher anxiety, and [blank_start]superior[blank_end] recall of the stimuli for phobic individuals compared to nonphobics.

Affect refers to:

What was Darwin's hypothesis regarding emotional expression?

The more naturally expressive subjects were [blank_start]less[blank_end] physiologically reactive to an emotional stressor than non-expressive persons, shown by SC and HR measures. This suggested that the differential physiological responding may be related to personality and cognitive style of expressive versus inhibited persons.

Discharge model of emotion suggests:

Bottle feeders reported more desire to pick up their infants, and had higher SCL and HR.

Electrodermal recovery rate is:

Subjects with large-amplitude SCRs when they detected a signal made fewer commission errors than those with small detection-related SCRs.

Persons whose SCRs habituate slowly are superior in auditory vigilance performance, because they detect more signals and show less decline in detection over time.

Better detection performance is related to lower levels of EDA, an indicator of PNS activity.

Prosopagnosia subjects (caused by brain damage at occipital and parietal areas on both sides of the brain) generated more frequent and significantly larger SCRs to faces of persons they had known but were now unable to recognise. They did not produce such SCR to slides of unfamiliar faces

Examples of autonomic discrimination without awareness include:

In the Neuronal model, Sokolov suggested that if the incoming existing neuronal models the OR:

The Neuronal model is primary involved with:

There has been evidence that the OR magnitude depends on the amount of stimulus change

In the Information-processing model, the OR is produced when a match is not found in:

In information processing model: The cognitive effort of searching long-term memory results in registration of the novel stimulus in [blank_start]long-term[blank_end] memory. The processing facilitates later retrieval, but produces [blank_start]inhibition[blank_end] of the OR because there is a match between the stimulus and memory trace is made.

The EDA response to missing stimuli takes longer than the production of an EDA to actual stimuli.

If conditioned stimulus is greater than or equal to the intensity of an unconditioned stimulus, then conditioning to that conditioned stimulus should not occur.

Which type of faces produced greater resistance to extinction?
