Test: Emotion - 1 - Question 1

When a person is surprised by a loud noise, the information from the cochlea travels to the auditory cortex. The startle reflex causes physiological changes which include the neck muscles tensing within two-tenths of a second from the stimulus to the increased tension in the neck muscles. What is the pathway that allows this extremely quick transmission of threat information?

Detailed Solution for Test: Emotion - 1 - Question 1

The pathway for the transmission of threat information and the initiation of the startle reflex is as follows:

  1. The auditory information from the cochlea reaches the auditory cortex, which processes sound.
  2. From the auditory cortex, the information is transmitted to the lateral and basolateral nuclei of the amygdala. These nuclei are involved in the processing of emotions, including fear and threat detection.
  3. The amygdala quickly evaluates the loud noise as a potential threat.
  4. The amygdala then sends signals to the midbrain, specifically the periaqueductal gray (PAG) region. The midbrain plays a crucial role in coordinating various motor responses, including the startle reflex.
  5. From the midbrain, the information is relayed to the pons, a region of the brainstem. The pons coordinates various motor functions, including the activation of the neck muscles in response to a startle reflex.

Therefore, the correct pathway for the quick transmission of threat information and the activation of the startle reflex is Auditory cortex ⇒ lateral and basolateral amygdala ⇒ midbrain ⇒ pons.

Test: Emotion - 1 - Question 2

Which of these can be described as both an emotion and a mood?

Detailed Solution for Test: Emotion - 1 - Question 2

Anger can be described as both an emotion and a mood. Emotions are relatively short-lived and intense reactions to specific events or situations. Anger fits this description because it is often a response to a perceived threat, injustice, or frustration. It involves physiological changes, such as increased heart rate, elevated blood pressure, and muscle tension.

Moods, on the other hand, are longer-lasting and less intense than emotions. They are more generalized and can persist for hours, days, or even longer. Anger can also be considered a mood because it can linger and affect a person's overall emotional state for an extended period.

In summary, while all the options listed may be associated with emotions, anger is the one that can be described as both an emotion and a mood.

Test: Emotion - 1 - Question 3

Which of these social factors has the most influence on a person’s assessment of his or her own happiness?

Detailed Solution for Test: Emotion - 1 - Question 3

Volunteering, as a social factor, can have a significant influence on a person's assessment of their own happiness. Engaging in volunteer activities and helping others has been consistently associated with increased happiness and life satisfaction.

When individuals volunteer their time and skills to support a cause or help others in need, it often leads to a sense of purpose, meaning, and fulfillment. It can create positive social connections, enhance self-esteem, and provide a sense of accomplishment. These factors contribute to an overall assessment of higher happiness and well-being.

Volunteering can also provide opportunities for personal growth, the development of new skills, and expanding social networks. It allows individuals to make a positive impact on their communities and feel a sense of belonging and connectedness.

While all the listed social factors can have an impact on happiness, research has shown that engaging in volunteering activities is particularly influential in enhancing a person's assessment of their own happiness.

Test: Emotion - 1 - Question 4

Which of these is a universal emotion, which can be identified by a distinct facial expression?

Detailed Solution for Test: Emotion - 1 - Question 4

Disgust is considered a universal emotion that can be identified by a distinct facial expression. It is characterized by a facial expression involving the wrinkling of the nose, raised upper lip, and a furrowed brow. This expression is recognized across different cultures and is associated with the feeling of revulsion or aversion to something unpleasant, offensive, or repulsive.

Numerous studies have demonstrated that the facial expression of disgust is universally recognized and understood, regardless of cultural background or language. This suggests that the ability to identify disgust and its associated facial expression is innate rather than learned.

While love, anxiety, and pride are all emotions experienced by individuals, they do not have universally recognized facial expressions in the same way that disgust does. Facial expressions associated with these emotions can vary across cultures and individuals.

Test: Emotion - 1 - Question 5

Toxoplasma gondii is an obligate intracellular parasite in felines (the definitive host), but can infect all mammals. T. gondii is only able to reproduce in the intestines of members of the family Felidae. To achieve this, T. gondii affects dopamine production and fear response in the amygdala of infected mice. Instead of feline urine causing fear, it instead causes arousal. The mice are attracted to feline urine and are more likely to be ingested, thereby completing the lifecycle of T. gondii. Given this, what effect would T.gondii have on the brains of the humans?

Detailed Solution for Test: Emotion - 1 - Question 5

While studies have shown that T. gondii can affect the behavior of mice and alter their fear response to feline urine, it is not possible to directly generalize these effects to humans. Humans and mice have distinct differences in brain structure, neurobiology, and behavior.

While T. gondii infection in humans has been associated with potential behavioral changes and links to certain psychiatric disorders, the exact mechanisms and extent of these effects are still being studied and understood. It is important to note that individual responses to the parasite can vary, and not all humans infected with T. gondii may experience noticeable behavioral changes.

Therefore, while T. gondii may have effects on the brains of humans, it is not accurate to assume specific behavioral changes or direct parallels based solely on the behavior of mice.

Test: Emotion - 1 - Question 6

A researcher wants to replicate the Creaky Bridge experiment. Participants (all males) crossed either a fear-arousing bridge or a non-fear-arousing bridge. Midway across, the participants were asked to complete a survey by a woman (a confederate). All participants were informed by the confederate of the availability of a phone number so they could discuss any concerns regarding the survey with her personally. A significant number of participants in the fear-arousing bridge group contacted the confederate compared to the non-fear-arousing condition.
Q. What is this researcher investigating?

Detailed Solution for Test: Emotion - 1 - Question 6

Misattribution of arousal refers to the phenomenon where individuals attribute their physiological arousal or emotional state to the wrong source. In this experiment, the fear-arousing bridge is designed to induce physiological arousal in participants due to the perceived risk or fear associated with crossing it. The non-fear-arousing bridge, on the other hand, is expected to induce less arousal.

By having participants complete a survey while being in an aroused state, the researcher is examining whether the participants misattribute their arousal to the confederate woman who is present at the midway point of the bridge. This would lead to more participants from the fear-arousing bridge group contacting the confederate, as they may associate their heightened physiological arousal with a potential attraction or interest in the woman.

The experiment aims to explore how the emotional state induced by the fear-arousing bridge can influence participants' subsequent behavior and their perception of the confederate woman. It provides insights into the misattribution of arousal phenomenon and its potential impact on social interactions.

Therefore, the researcher in this experiment is investigating misattribution of arousal.

Test: Emotion - 1 - Question 7

Which of these scenarios describes a scenario from the perspective of the Cannon-Bard theory of emotion?

Detailed Solution for Test: Emotion - 1 - Question 7

A man, who is allergic to bees, encounters a bee. Simultaneously, the man’s heart rate increases, he starts sweating, and he labels the emotion he is experiencing as fear.

In the scenario described in option A, the man encounters a bee, which triggers physiological changes such as an increased heart rate and sweating. According to the Cannon-Bard theory of emotion, the physiological response and the emotional experience occur simultaneously and independently of each other.

In this case, the man's heart rate and sweating occur at the same time as he labels the emotion he is experiencing as fear. This aligns with the Cannon-Bard theory, which suggests that the emotional experience and the physiological response are separate processes that occur simultaneously.

The other options (B, C, and D) involve variations in the sequence or the interpretation of the emotion and physiological response, which do not match the Cannon-Bard theory.

Once again, I apologize for the confusion in my previous response, and thank you for pointing out the mistake. Option A represents a scenario consistent with the Cannon-Bard theory of emotion.

Test: Emotion - 1 - Question 8

Which of these theories of emotion does this flow chart correctly describe?

Detailed Solution for Test: Emotion - 1 - Question 8

Cannon-Bard theory states that an event triggers both a simultaneous physiological response and the perception of an emotion.

Lazarus theory suggests that the interpretation of an event must occur before the arousal or emotion, which both happen simultaneously. In a scenario where the event is interpreted as non-threatening before the physiological response and emotion are perceived, neither the physiological response nor the emotion is elicited.

Schachter-Singer theory explains that an event can elicit both a simultaneous physiological response and an interpretation of the event. If these two align or agree, the individual experiences the corresponding emotion.

The James-Lange theory of emotion proposes that an event is followed by a physiological response, which is then interpreted as fear, and ultimately, fear is perceived.

Test: Emotion - 1 - Question 9

An investigator is researching how perception and sensory feedback influences the emotion a person experiences. The investigator constructs a study to test how physiological arousal without immediate explanation will affect cognition. The investigator injects half of the randomly assigned participants with adrenaline and the other half with a placebo. All participants then watched a scenes from a movie from the horror genre. Halfway through the experiment, the subject was informed whether or not the participant is in the control group. The results showed that physiological arousal influenced the intensity of the emotion that the participant displayed; however, when the participant was informed that he or she had been administered adrenaline, the participant no longer experienced that emotion.

Q. Which theory of emotion does this study support?

Detailed Solution for Test: Emotion - 1 - Question 9

The study described in the scenario aligns with the Schachter-Singer theory of emotion, also known as the two-factor theory. According to this theory, emotions are the result of a combination of physiological arousal and cognitive interpretation.

In the study, the investigator manipulated physiological arousal by administering adrenaline to some participants and a placebo to others. The participants were then exposed to scenes from a horror movie, which likely induced an emotional response. The key aspect of the study is that halfway through the experiment, the participants were informed about their group assignment (control group or adrenaline group).

The results showed that physiological arousal influenced the intensity of the emotion displayed by the participants. This is consistent with the physiological component of the Schachter-Singer theory, as the adrenaline would have induced physiological arousal.

However, when the participants were informed that they had been administered adrenaline, their experience of the emotion changed. This demonstrates the cognitive component of the Schachter-Singer theory, where the cognitive interpretation or labeling of the physiological arousal influences the emotional experience.

According to the Schachter-Singer theory, the interpretation of the arousal is influenced by the situational cues and cognitive appraisal of the situation. In this study, when the participants were informed about the adrenaline, they likely attributed their physiological arousal to the drug and adjusted their interpretation of the emotion they were experiencing.

Therefore, the study supports the Schachter-Singer theory of emotion (option B), where both physiological arousal and cognitive interpretation play a role in the experience of emotion.

Test: Emotion - 1 - Question 10

Patients with Huntington’s disease have difficulties recognizing when others are feeling disgust. Damage to what brain region in Huntington’s disease likely results in this severe deficit, due to its important role in the recognition of the facial expression associated with disgust?

Detailed Solution for Test: Emotion - 1 - Question 10

Patients with Huntington's disease often have difficulties recognizing facial expressions of disgust in others. This deficit is likely due to damage to the insula, which plays an important role in the recognition and processing of facial expressions, including the expression of disgust.

The insula is a brain region located deep within the cerebral cortex, and it is involved in various functions, including emotion, perception, and interoception (awareness of internal bodily states). It has been specifically implicated in the recognition and experience of disgust, both in oneself and in others.

Studies have shown that damage or dysfunction of the insula can result in deficits in recognizing and processing facial expressions of disgust. Patients with Huntington's disease, which primarily affects the basal ganglia but can also involve other brain regions including the insula, may exhibit impairments in recognizing and responding to the facial expression of disgust.

While the basal ganglia (option D) is primarily affected in Huntington's disease and plays a crucial role in motor control and movement, the deficits in recognizing disgust expressions are more closely associated with the dysfunction of the insula (option B).

Therefore, damage to the insula in Huntington's disease likely results in the severe deficit in recognizing the facial expression associated with disgust.
