Which method of threshold detection involves taking the average of the reversal
points to find the absolute threshold

Which method of measuring absolute threshold best corresponds to: Adjust intensity until stimulus is detected, repeat to find average intensity (FASTEST)

Which method of measuring absolute threshold best corresponds to: similar to limits but instead personalized to participant, reversal when stimulus can't be detected, average the reversals for threshold

Which method of measuring absolute threshold best corresponds to: decreasing of ascending strength of stimulus until crossover point (when answer changes), the avg of crossover points is the absolute threshold

Which method of measuring absolute threshold best corresponds to: present same number of different intensity stimuli in random order, threshold found when stimuli is detected 50% of the time (MOST ACCURATE)

T/F RGCS transmit signals directly to the primary visual cortex V1

The principle of ___ states that the object that we actually perceive is based on interaction of our nervous system with the proximal stimulus

In the perceptual process, ___ is the transformation of one form of energy to another

The clinical disorder of visual form agnosia was provided as an example of how we might fail to ___ an object, even though we detect the features of the object

In lecture, we did a priming experiment in which the prior images that people viewed influenced how they were likely to interpret an ambiguous rat-man picture. This was an example of how _______________________ affects perception and recognition.

In a perception experiment, you would like to measure the experience of the participant in response to some stimulus being presented. Since their experience is not directly observable, the experimenter must specify _______________ which give us something that can be observed and measured.

Which of the quantitative methods listed below is most accurate when attempting to find the absolute threshold for detecting a stimulus?

In lecture, which of the classical methods of determining the detection threshold did we say would use the data gathered from the participant to estimate the point at which the stimulus would be detected 50% of the time?

When determining the difference threshold for a given sensory dimension, Weber's law suggests that as the absolute value of the standard increases, the value of the JND (DL) will _________.

Response ________ in a magnitude estimation experiment occurs when doubling the stimulus intensity LESS than doubles the subjective magnitude of the stimulus.

Which structure or substance provides the most focal power in the eye?

An elderly woman finds that she needs to hold the newspaper farther and farther away to be able to read it. This indicates that her near point is increasing and she most likely has:

When working correctly in a young adult, the cornea and lens will focus light on to the back of the retina. When the cornea or lens causes the focal point to be beyond the retina, this is most generally called __________.

Floaters are the cellular debris located in the ...

When a photon of light causes the retinal molecule on an opsin strand to change shape and eventually break off, this specific process is called __________.

T/F Rods and cones are the only cells in the eye that transduce incoming light.

The foveal portion of the retina contains only cones -- about 50,000 - 110,000 of them. These provide great detail on items in the central focus of vision. ___________ is a condition in which primarily the fovea and immediately surrounding region are damaged, causing a loss of sight in this area.

After 3 to 4 minutes in the dark, which receptors would (generally) be most adapted?

In lecture, we discussed the spectral sensitivity and placement of different types of receptors. In general, _________ are the most common type of cone found in the eye.

According to our discussion in lecture, the  ________________________ helped originate the idea of sensory modularity. This is the notion that specific circuits or areas of the brain are primarily specialized for processing certain types of sensory information.  

When multiple axons connect to a single neuron, this is specifically called __________.

Single-cell recordings in the horseshoe crab were used to explore the phenomenon of:

In general, cells in the ___________ of the retina should have the greatest amount of lateral inhibition.
