Buford complains that he can play his tuba beautifully at home, but each time he tries to play at the local talent show he sounds like a bull elk in rutting season. His problem is explained by ___________________.
Correct Answer
A. The Yerkes-Dodson Law
Explanation
The Yerkes-Dodson Law suggests that performance is optimal at a moderate level of arousal. In Buford's case, he is able to play his tuba beautifully at home because he is likely in a comfortable and familiar environment, resulting in a lower level of arousal. However, when he tries to play at the local talent show, the increased pressure and unfamiliarity of the situation may cause him to become overly aroused, leading to a decline in performance and sounding like a bull elk in rutting season.
3.
According to the Cannon-Bard theory,
Correct Answer
A. The thalamus plays a central role in producing emotions.
Explanation
According to the Cannon-Bard theory, the thalamus plays a central role in producing emotions. This theory suggests that emotions are experienced simultaneously with physiological responses, and the thalamus is responsible for relaying sensory information to the brain. It is believed that the thalamus receives sensory input and sends signals to both the cortex (where cognitive processing occurs) and the autonomic nervous system (which controls physiological responses). Therefore, the thalamus is involved in the production of emotions by coordinating the communication between the sensory input and the physiological response.
4.
People from different cultures can recognize which facial expressions?
Correct Answer
D. All of these
Explanation
People from different cultures can recognize all of these facial expressions. Facial expressions are a universal form of nonverbal communication that can convey emotions such as fear, anger, and disgust. While there may be slight variations in the interpretation or intensity of these expressions across cultures, the basic recognition of these emotions through facial expressions is widely shared among humans.
5.
If the lateral hypothalamus is destroyed, a rat will ________________________.
Correct Answer
D. Refuse to eat until force-fed
Explanation
If the lateral hypothalamus is destroyed, a rat will refuse to eat until force-fed. The lateral hypothalamus is responsible for regulating hunger and appetite. When it is destroyed, the rat loses its ability to feel hunger and the motivation to eat. As a result, it will not eat voluntarily and will only consume food when it is forced to do so.
6.
If the ventromedial hypothalamus is destroyed, a rat will ______________.
Correct Answer
A. Eat until it becomes obese
Explanation
If the ventromedial hypothalamus is destroyed, a rat will eat until it becomes obese. The ventromedial hypothalamus is responsible for regulating feelings of satiety and controlling food intake. When it is damaged, the rat loses the ability to feel full and continues to eat excessively, leading to obesity.
7.
Intrinsic motivation occurs when ________________.
Correct Answer
B. There is no obvious external reward for one's behavior.
Explanation
Intrinsic motivation occurs when there is no obvious external reward for one's behavior. This means that individuals engage in an activity because they find it inherently enjoyable, interesting, or satisfying, rather than for any external benefits or incentives. Intrinsic motivation is driven by internal factors such as personal interest, curiosity, or a sense of accomplishment. It is often associated with higher levels of engagement, creativity, and long-term satisfaction.
8.
The hypothalamus has __________ hunger center(s).
Correct Answer
C. The most direct control over
Explanation
The hypothalamus has the most direct control over hunger. The hypothalamus is a region in the brain that plays a crucial role in regulating appetite and food intake. It contains specialized cells called hunger center, which are responsible for initiating feelings of hunger and regulating the body's energy balance. This means that the hypothalamus has the most direct influence on hunger and is involved in signaling when the body needs to eat.
9.
Push is to pull as __________ is to __________.
Correct Answer
D. Drive; incentive
Explanation
The relationship between "push" and "pull" reflects an opposite action. Similarly, the relationship between "drive" and "incentive" indicates a motivational force propelling action. In both cases, one term represents a force or action, while the other represents the motivating factor or direction influencing that action.
10.
Unlearned biological motives necessary for survival are termed
Correct Answer
A. Primary motives
Explanation
Primary motives refer to the innate biological drives that are necessary for an individual's survival, such as hunger, thirst, and sexual desire. These motives are unlearned and are essential for the individual's well-being and survival. Secondary motives, on the other hand, are learned motives that are not necessary for survival but are driven by social and psychological factors. Drives and stimulus motives are also related to motivation but do not specifically refer to the unlearned biological motives necessary for survival.
11.
Which theory of emotion holds the view that bodily changes PRECEDE emotion and that we experience an emotion AFTER our body reacts?
Correct Answer
D. The James-Lange theory
Explanation
The James-Lange theory of emotion suggests that our bodily changes occur before we experience an emotion. According to this theory, our body reacts to a stimulus, and then we interpret those bodily changes as a specific emotion. For example, if we encounter a dangerous situation, our body may first experience a rapid heartbeat and increased sweating, and then we interpret these physical changes as fear. This theory suggests that our emotions are a result of our bodily responses.
12.
In hunger, a set point is __________________.
Correct Answer
C. Related to the proportion of body fat your body normally maintains.
Explanation
The set point in hunger refers to the proportion of body fat that your body normally maintains. This means that when your body reaches a certain level of body fat, it triggers hunger signals to maintain that level. It is similar to a thermostat for blood sugar, which regulates the body's blood sugar levels. It is not related to the weight you maintain when you attempt to diet or determined by adult eating habits.
13.
What is the correct order of needs in Maslow's hierarchy?
Correct Answer
C. pHysiological; safety; love and belonging; esteem; self-actualization
Explanation
The correct order of needs in Maslow's hierarchy is physiological, safety, love and belonging, esteem, and self-actualization. This order suggests that individuals must first fulfill their basic physiological needs such as food, water, and shelter before moving on to the need for safety and security. Once these needs are met, individuals seek love and belonging, followed by the need for esteem and recognition from others. Finally, self-actualization, which refers to the realization of one's full potential and personal growth, becomes the ultimate goal.
14.
According to Maslow's theory, basic needs include ________________________.
Correct Answer
A. pHysiological needs, safety, and security
Explanation
According to Maslow's theory of hierarchy of needs, basic needs include physiological needs, safety, and security. This means that individuals need to fulfill their basic physiological needs such as food, water, and shelter, as well as feel safe and secure in their environment. These needs form the foundation of Maslow's hierarchy, as they must be met before individuals can move on to fulfilling higher-level needs such as love, belonging, and self-esteem.
15.
Which theory holds that we are afraid because we run or are angry because we strike?
Correct Answer
B. James-Lange
Explanation
The James-Lange theory holds that our emotions are a result of our physical responses to stimuli. According to this theory, we feel afraid because we run away from something or angry because we strike something. In other words, our emotions are a direct result of our bodily reactions.
16.
At the top of Maslow's hierarchy of motives are _________________.
Correct Answer
C. Self-actualization
Explanation
Self-actualization refers to the highest level of motivation in Maslow's hierarchy of needs. It represents the fulfillment of one's potential and the desire to become the best version of oneself. This level is characterized by personal growth, self-discovery, and the pursuit of meaningful goals. It encompasses aspects such as creativity, problem-solving, and self-fulfillment. Self-actualization is considered the ultimate goal of human motivation, as it allows individuals to fully realize their capabilities and find a sense of purpose and fulfillment in life.
17.
Which theory claims that emotions are organized in the brain and that emotional feelings and bodily expressions occur simultaneously?
Correct Answer
B. The Cannon-Bard theory
Explanation
The Cannon-Bard theory claims that emotions are organized in the brain and that emotional feelings and bodily expressions occur simultaneously. This theory suggests that when we experience an emotion, such as fear or happiness, our brain processes this information and triggers both the physiological response (such as increased heart rate or sweating) and the subjective experience of the emotion at the same time. This is in contrast to the James-Lange theory, which proposes that the physiological response comes before the subjective experience of the emotion.
18.
A part of the nervous system that prepares the body for emergencies is the __________ division.
Correct Answer
B. Sympathetic
Explanation
The sympathetic division of the nervous system is responsible for preparing the body for emergencies. It activates the fight-or-flight response, increasing heart rate, blood pressure, and respiration, while also suppressing non-essential functions such as digestion. This division helps the body respond quickly and effectively to perceived threats or stressful situations.
19.
A circadian rhythm refers to a cycle
Correct Answer
B. Of bodily activity approximately 24 hours in length.
Explanation
A circadian rhythm refers to a cycle of bodily activity approximately 24 hours in length. This means that certain bodily functions, such as sleep-wake cycles, hormone production, and body temperature, follow a regular pattern that repeats every 24 hours. This rhythm is regulated by an internal biological clock, which helps to synchronize our body's functions with the natural day-night cycle.
20.
The __________ describes the relationship between arousal level, task difficulty, and efficiency of performance.
Correct Answer
C. Yerkes-Dodson Law
Explanation
The Yerkes-Dodson Law describes the relationship between arousal level, task difficulty, and efficiency of performance. According to this law, there is an optimal level of arousal for each task, and performance is best when arousal is moderate. As arousal levels increase, performance improves up to a certain point, after which further increases in arousal lead to a decline in performance. This law suggests that both low and high levels of arousal can negatively impact performance, and that there is an inverted-U shaped relationship between arousal and performance.
21.
Which of the following is an assumption of arousal theory?
Correct Answer
D. Optimal levels of arousal exist for various activities.
Explanation
Arousal theory suggests that individuals have an optimal level of arousal for different activities. This means that different tasks or activities require different levels of arousal in order for individuals to perform at their best. Some activities may require higher levels of arousal to enhance performance, while others may require lower levels. Therefore, the assumption of arousal theory is that optimal levels of arousal exist for various activities.
22.
Electrically stimulating the lateral hypothalamus will cause a rat to
Correct Answer
A. Start eating
Explanation
Electrically stimulating the lateral hypothalamus triggers the activation of hunger centers in the brain, leading to an increase in appetite and the initiation of eating behavior. This region plays a crucial role in regulating feeding behavior and is responsible for initiating the motivation to eat. Therefore, when the lateral hypothalamus is stimulated, it prompts the rat to start eating.
23.
The body structure most closely associated with thirst is the
Correct Answer
C. Hypothalamus
Explanation
The hypothalamus is the body structure most closely associated with thirst. It is responsible for regulating various bodily functions, including the sensation of thirst. When the body is dehydrated, the hypothalamus detects this and triggers the sensation of thirst, prompting the individual to seek out and consume fluids. Additionally, the hypothalamus controls the release of antidiuretic hormone (ADH), which helps regulate fluid balance in the body. Therefore, the hypothalamus plays a crucial role in maintaining proper hydration levels.
24.
Extrinsic motivation stems from
Correct Answer
A. Obvious external factors
Explanation
Extrinsic motivation stems from obvious external factors, such as rewards, praise, or punishment. These external factors serve as incentives to engage in a certain behavior or task. Unlike intrinsic motivation, which comes from within and is driven by personal enjoyment or satisfaction, extrinsic motivation relies on external rewards or consequences to drive behavior. This can include things like money, recognition, or social approval. These external factors provide a tangible reason for individuals to perform a task or achieve a goal, even if they may not have a personal interest or enjoyment in the activity itself.
