Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 1

A team of developmental psychologists are testing the taste sensation in children. The researchers want to make sure that the tastants utilized do not interact with charged particles. Which of these tastant combinations should the researcher use?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 1

The combination of a sweet tastant and an umami tastant would ensure that the tastants do not interact with charged particles. Sweet taste is typically associated with the detection of sugars, which are not charged particles. Umami taste, as mentioned earlier, is associated with the detection of amino acids, which are also not charged particles. Therefore, using a combination of a sweet tastant and an umami tastant would meet the researcher's requirement of avoiding interactions with charged particles.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 2

Which of these papillae categories does not contain taste buds?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 2

Filiform papillae are the smallest and most numerous type of papillae on the human tongue, but they do not contain taste buds. Instead, they primarily function in providing a rough texture to the tongue's surface and are involved in tactile sensations. Unlike circumvallate, fungiform, and foliate papillae, filiform papillae do not have taste buds present on their surface.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 3

Which statement describes a difference between the pathways for taste and the pathways for vision, hearing, and touch?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 3

This statement describes a difference between the pathways for taste and the pathways for vision, hearing, and touch. In the case of taste, the sensory information is primarily processed and perceived from the ipsilateral side, meaning that the signals from the taste receptors on one side of the tongue are processed on the same side of the brain. On the other hand, for vision, hearing, and touch, the sensory information is mostly processed in a contralateral manner, meaning that the signals from one side of the body are processed on the opposite side of the brain. This contralateral processing is a characteristic feature of the pathways for vision, hearing, and touch.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 4

Which of these is NOT a theory of how odor is coded in the brain?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 4

The gate control theory of olfaction is not a theory of how odor is coded in the brain. It is a theory that applies to pain perception and suggests that the experience of pain can be modulated by the activation of specific neural mechanisms that act as "gates" to either allow or block pain signals from reaching the brain. This theory does not directly relate to the coding of odor in the brain.

On the other hand, the other options are theories that propose different mechanisms for how odor is coded in the brain:

B. Vibrational theory of olfaction suggests that odorant molecules vibrate at specific frequencies, and the receptors in the nose detect these vibrations to distinguish different odors.

C. Labeled-line theory of olfaction proposes that specific odorant receptors in the nose are selectively activated by different odor molecules, and these receptors send specific signals to the brain that correspond to different odors.

D. Steric theory of olfaction suggests that the shape and size of odorant molecules determine their odor qualities, and the receptors in the nose detect these molecular features to identify different odors.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 5

Many studies have shown auditory processing occurs in sleep. This is the premise behind smoke detectors. A smell researcher is interested in whether smell can be utilized in a similar fashion. The researcher chooses two odors, peppermint and pyridine. Although peppermint and pyridine have different hedonic valence, the trigeminal strength of the two odors was equal.
Why was trigeminal strength controlled in this experiment?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 5

The trigeminal nerve is responsible for transmitting sensory information from the face, including sensations such as touch, pain, and temperature. In the context of smell, the trigeminal nerve can also be stimulated by certain odorous compounds, leading to sensations of irritation, cooling, or warmth in the nasal cavity.

By controlling for the trigeminal strength of the two odors in the experiment, the researcher ensures that any differences in perception or response to the odors are not solely due to differences in trigeminal stimulation. If the trigeminal strength of the two odors were not controlled, the participants' responses might be influenced by the varying trigeminal sensations produced by each odor, rather than the odor's specific qualities or hedonic valence.

Controlling for trigeminal strength allows the researcher to isolate and examine the specific effects of the odor itself, independent of any trigeminal stimulation, and determine whether smell can be utilized in a manner similar to auditory processing in sleep, as hypothesized.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 6

One tool that smell researchers use to investigate the role of pheromones on emotion, motivation, and cognition is called an emotional Stroop test. Similar to the typical Stroop test, a participant will show interference, increased latency, to name the color of the words that have an emotional connotation to the participant. Utilizing this test, smell researchers investigated the effects of ∆4,16-androstadien-3-one (androstadienone) which appears to function as a pheromone in humans. A cotton swab diluted in a strongly fragranced carrier solution before being applied to the upper lip of each participant. The carrier solution alone was administered to the control participants. Both groups were primed with a narrative discussing either a positive or negative emotional experience. The groups were then given a test with either positive or negatively valenced words, based on the narrative type. The effects of both narrative conditions for both groups of participants and the neutral word list are shown in Figure.
What conclusion can be made from the Figure?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 6
  • Pheromones cause automatic behavioral effects in members of the same species. In humans, these effects are much more subtle, and can be tested by the pheromone’s modulation of attention, emotion, or cognition.
  • Interference occurs when the participant takes longer to read a word because it is emotionally charged than a neutral word.
  • The interference experienced when naming emotionally valenced words was increased by the administration of androstadienone.
  • The administration of androstadienone had no effect on color naming with neutral words.
  • The experimental group showed a more pronounced interference effect in the positive and negatively valenced tasks, but no difference in the neutral words task.
Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 7

Where is the first place in the brain where the olfaction and gustation systems integrate?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 7

The first place in the brain where the olfaction and gustation systems integrate is the orbitofrontal cortex. The orbitofrontal cortex is a region in the frontal lobes of the brain that is involved in the processing and integration of sensory information, including olfactory and gustatory inputs. It plays a crucial role in the perception and evaluation of taste and smell, as well as the integration of these sensory modalities with other cognitive and emotional processes. The orbitofrontal cortex receives inputs from the olfactory bulb (part of the olfactory system) and the gustatory system, allowing for the integration and interpretation of taste and smell sensations.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 8

Which answer describes the correct pathway that a signal takes from the olfactory mucosa to the frontal lobe of the brain?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 8

The correct answer is A. The olfactory pathway begins with the olfactory receptors in the olfactory mucosa, located in the upper part of the nasal cavity. From there, the olfactory information is transmitted to the olfactory bulb, where the signal is processed and relayed to the amygdala and the piriform cortex. The amygdala plays a role in emotional processing and the piriform cortex is involved in olfactory perception. Finally, the processed information is transmitted to the orbitofrontal cortex, which is responsible for further processing, integration, and evaluation of olfactory sensations, as well as the association of odors with emotional and cognitive responses.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 9

Which cranial nerve is primarily responsible for transmitting olfactory (smell) information from the nasal cavity to the brain?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 9

The olfactory nerve, also known as cranial nerve I, is primarily responsible for transmitting olfactory (smell) information from the olfactory receptors in the nasal cavity to the brain. Cranial nerve II (Optic nerve) is responsible for vision, cranial nerve V (Trigeminal nerve) is responsible for sensations in the face, including touch and pain, and cranial nerve VII (Facial nerve) is responsible for gustatory (taste) information from the anterior two-thirds of the tongue.

Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 10

Which part of the brain is primarily responsible for processing and interpreting complex odor information?

Detailed Solution for Test: Taste (Gustation) and Smell (Olfaction) - 1 - Question 10

The temporal lobe is primarily responsible for processing and interpreting complex odor information. It is involved in the recognition and identification of specific smells. The frontal lobe is associated with higher-order cognitive functions, the occipital lobe with visual processing, and the parietal lobe with sensory integration and spatial awareness.
