Which effect is likely to result from damage to the amygdala?
Single case studies have thus far indicated that amygdala damage: (i) impairs memory for emotional events; (ii) impairs the processing of certain emotion expressions; and (iii) compromises social development and functioning.
Which of the following problems is most likely to result in an increased ability to identify the emotional expression of people viewing pleasant and unpleasant pictures?
What problems would most likely result in an increased ability to identify the emotional expression of people viewing pleasant and unpleasant pictures? Damage to the left hemisphere. Investigators have found that individuals who suffer prefrontal cortex damage: Often make bad decisions.
What part of the brain is key for learned fears?
The fear response starts in a region of the brain called the amygdala. This almond-shaped set of nuclei in the temporal lobe of the brain is dedicated to detecting the emotional salience of the stimuli – how much something stands out to us.

What is the amygdala responsible for?
The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
What happens when the amygdala detects a threat to survival?
If the amygdala senses danger, it makes a split-second decision to initiate the fight-or-flight response before the neocortex has time to overrule it. This cascade of events triggers the release of stress hormones, including the hormones epinephrine (also known as adrenaline) and cortisol.
Which type of leukocyte destroys tumor cells and cells infected with viruses?
Infected cells are identified and destroyed by natural killer (NK) cells, lymphocytes that can kill cells infected with viruses or tumor cells (abnormal cells that uncontrollably divide and invade other tissue).
Which theory tells that emotions occur when physical arousal is labeled or interpreted on the basis of experience and situational cues?
The two-factor theory of emotion focuses on the interaction between physical arousal and how we cognitively label that arousal. In other words, simply feeling arousal is not enough; we also must identify the arousal in order to feel the emotion.
What is an example of the Cannon Bard theory?
What is this? The Cannon-Bard theory of emotion states that stimulating events trigger feelings and physical reactions that occur at the same time. For example, seeing a snake might prompt both the feeling of fear (an emotional response) and a racing heartbeat (a physical reaction).
What part of the brain controls love?
The hypothalamus is one of the brain regions that makes up the limbic system and is often considered the main control centre of love.
Is fear an emotion?
Fear is one of the most basic human emotions. It is programmed into the nervous system and works like an instinct. From the time we're infants, we are equipped with the survival instincts necessary to respond with fear when we sense danger or feel unsafe.
Do emotions come from the heart or brain?
Psychologists once maintained that emotions were purely mental expressions generated by the brain alone. We now know that this is not true — emotions have as much to do with the heart and body as they do with the brain. Of the bodily organs, the heart plays a particularly important role in our emotional experience.
Why do certain people suspect that a diet high in corn may lead to an increase in aggressive behavior?
Why do certain people suspect that a diet high in corn may lead to an increase in aggressive behavior? Corn is low in tryptophan and high in phenylalanine.
Which theory asserts that we experience emotion after we experience autonomic arousal?
The James-Lange theory of emotion asserts that emotions arise from physiological arousal.
What common measure of fear or anxiety is popular because it can be used with non humans as well as humans quizlet?
The common measure of fear or anxiety that is popular because it can be used with non-humans as well as humans is: the startle response.
What is amygdala and hippocampus?
The amygdala is specialized for input and processing of emotion, while the hippocampus is essential for declarative or episodic memory. During emotional reactions, these two brain regions interact to translate the emotion into particular outcomes.
What is Broca's area function?
Broca's area is a key component of a complex speech network, interacting with the flow of sensory information from the temporal cortex, devising a plan for speaking and passing that plan along to the motor cortex, which controls the movements of the mouth.
What does the nucleus accumbens do?
Introduction: The nucleus accumbens is considered as the neural interface between motivation and action, playing a key role on feeding, sexual, reward, stress-related, drug self-administration behaviors, etc.
What happens when your amygdala becomes triggered?
The amygdala triggers a person's fight-or-flight response. This leads to the release of hormones that prepare the body to fight the source of danger or flee from it. Amygdala hijack occurs when the amygdala activates the fight-or-flight response when there is no serious threat to a person's safety.
What happens when the amygdala is stimulated?
Stimulation of the amygdala causes intense emotion, such as aggression or fear. Irritative lesions of temporal lobe epilepsy have the effect of stimulating the amygdala. In its extreme form irritative lesions of temporal lobe epilepsy can cause a panic attack.
What is amygdala hijack phenomenon?
Amygdala hijack is an emotional response to stress, often thought of as losing control of one's emotions. An example of this is where you are talking to a friend and they do not appear to be listening to you, ignore what you say, or maybe talk over the top of you. This kind of interaction can make you 'snap'.
Which type of leukocyte destroys tumor cells and cells infected with viruses quizlet?
What do Natural Killer Cells do? Attack tumor cells and cells that are infected with viruses.
Where are leukocytes destroyed?
The lifespan of white blood cells ranges from 13 to 20 days, after which time they are destroyed in the lymphatic system. When immature WBCs are first released from the bone marrow into the peripheral blood, they are called "bands" or "stabs." Leukocytes fight infection through a process known as phagocytosis.
What destroys body cells that are infected with a pathogen?
The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen. The main cells of the immune system are lymphocytes known as B cells and T cells.
Which sequence of events in emotional responses is characteristic of the James-Lange theory of emotion?
James argues that the sequence of events in experiencing emotion is: Emotion stimulus → Physiological Response Pattern → Affective Experience.
Which of the following theories of emotion would explain that you see a bear feel a bear and then you run?
The James-Lange Theory of Emotion Your emotional reaction depends upon how you interpret those physical reactions. For example, suppose you are walking in the woods and see a grizzly bear. You begin to tremble, and your heart begins to race.
Which hypothesis is consistent with Schachter and Singer's study of physiological arousal and emotional experience?
facial feedback hypothesis. Which hypothesis is consistent with Schachter and Singer's study of physiological arousal and emotional experience? a. Activation of the central nervous system facilitates emotional experience.
