Below is a list of factors that may increase the chances of developing Post Traumatic Stress Disorder (PTSD). Which of these are likely to be factors?
I. Childhood neglect or abuse
II. Being threatened with a weapon
III. Witnessing traumatic events, such as death and killing
IV. Lacking a good support system
V. Having an on-going persistent chronic condition, such as heart disease or diabetes
All of these are factors that can contribute to PTSD, except for an on-going chronic physical health condition. On-going mental health conditions, such as depression and anxiety, can contribute to PTSD (usually in combination with more actue problems of experiencing or witnessing trauma), and physical conditions can increase the likelihood of depression, but alone, they do not increase the likelihood of developing PTSD.

A person who experienced a life-threatening accident, a natural disaster, or abuse can present with __________.
Post-traumatic stress disorder occurs when a person who has gone through a significant trauma, a life-threatening accident, a natural disaster, or abuse shows stress symptoms that impair the person's ability to function. Psychosomatic disorder is a real, physical disorder that has a psychological cause. Tension headaches have real pain caused by muscle spasm, but stress and anxiety have a role in causing the symptoms. Schizophrenia is a form of psychosis in which there is a loss of contact with reality. MRI and PET scans show brain abnormalities and changes in function. Panic disorder runs in families, but whether it is due to genetics or environment is not clear. Panic disorder is characterized by sudden, brief attacks of intense fear that cause physical symptoms. Epileptic-like activity in the brain is thought to be the cause of intermittent explosive disorder which is characterized by recurrent episodes of aggression toward people or property.

Panic disorders are considered to be one of the most frequent groups of anxiety disorders. Which of the following symptoms are characteristic of panic disorders?
Individuals with a panic disorder suffer from sudden, overwhelming and repeated attacks of terror, which can occur out of nowhere. Major changes in behavior and persistent anxiety over having further attacks are characteristic of panic disorders. Often external stimuli or internal thoughts can trigger these attacks.
The other choices are incorrect. The fear of no escape possibilities in crowded situations is considered to be one criteria of agoraphobia, not of panic disorder. The exaggerated fear of specific objects or situations is characteristic for phobic disorders, not of panic disorder. Last, generalized anxiety disorder is marked by the diffuse state of general worries and fears, which are not based on a specific object or event. This is not the best description listed to fit the characteristics for panic disorder.

If a person were diagnosed with agoraphobia, then which of the following scenarios would best describe their behavior due to the disorder?
Agoraphobia occurs when a patient fears situations that make them feel trapped, embarrassed, or helpless. They may fear an actual event or even simply the anticipation of an event. This is more likely to occur in a crowded area, such as a subway or metro bus, than it would simply interacting with a few strangers at a given time. In other words, they may experience a lack of desire to interact with strangers to avoid embarrassment, but that is not a situation in which they would feel trapped or helpless.

What is the most likely diagnosis in a 24-year-old man who avoids a job he really wants because of an intense fear that he will be humiliated or rejected when meeting unfamiliar people?
Social anxiety disorder is the correct answer. The fear is judged to be out of proportion to the actual risk of the social interactions and is causing significant impairment in occupational functioning, which is concerning for social phobia. Social anxiety disorder should be suspected when intense fear of social interactions, in which the individual may be scrutinized by others, is out of proportion to the actual threat of the social situation and causes significant impairment in important areas of functioning, and the fear is not better explained by some other mental disorder.

Which of these answers is an example of cultural assimilation?
Cultural assimilation is the process of adopting elements from another culture. Thus, the correct answer is a Native American changing his hairstyle to reflect the hairstyle of white people. It is the less powerful culture that most often adapts to the more powerful culture.

If a patient were diagnosed with claustrophobia, then which area of their brain would show increased activity in an MRI study?
The amygdala, along with the insular cortex and the limbic system, demonstrates hyperactivity when a person experiences high levels of fear and/or anxiety, and would show hyperactivity in a patient with an anxiety disorder.
On the other hand, the other choices are incorrect. For example, Wernicke's area is associated with comprehension of spoken language, while the occipital lobe is associated with visual perception. Last, the parietal lobe helps integrate various forms of sensory input with each other to create an understanding of the world.

A study done recently showed that several management approaches, in addition to behavioral therapy interventions, may be necessary in preschool-aged children with moderate to severe attention-deficit/hyperactivity disorder (ADHD). That is, medication and some alternative therapies may be needed for preschool-aged children with ADHD who do not respond or do not follow behavior therapy. The researchers evaluated disruptive behavior in 74 children four to five years of age who were followed for 24 months. The children were randomized to either behavior therapy plus placebo or behavior therapy plus methylphenidate, and ADHD-related behaviors were compared. Parents reported ADHD symptoms observed at 6, 12, and 24 months. The researchers also noted several signs and symptoms of adverse effects that may have been due to the medication, such as insomnia, anorexia, irritability, and reduced growth and weight gain. The researchers found the children who received behavior therapy plus methylphenidate had significant reductions in ADHD symptoms at all time points compared to children who received behavior therapy plus placebo.
Severity of ADHD was taken into account by presence of symptoms of marked impairment in social functioning. The researchers eliminated the possible role of delays in social development not specific to ADHD by analyzing children whose symptoms of social functioning impairment clearly resulted from inattention, hyperactivity, and impulsivity. Specifically, inattention was identified as the child wandering off task that was not due to lack of understanding or disobedience; hyperactivity was identified as excessive talking or fidgeting when not appropriate; and impulsivity was identified as hasty actions without forethought by the child and with significant potential to harm the child. Symptoms affecting the relationship and mental health of the child’s parents were also treated as reflective of severity of ADHD. For example, parents who experienced majorly reduced psychological well-being as a result of their child’s behavior reflected severe ADHD, and from the results, parents of children with severe ADHD who received behavior therapy plus methylphenidate reported a significant reduction in feeling unable to handle stress because of child’s behavior.
One of the researchers also found that use of some alternative therapies may be supported when combined with behavior therapy. In particular, there were decreases in hyperactive behaviors in children who were placed on additive-free diets. This finding may be of particular significance because eliminating artificial food additives may be done without risk of safety and avoids the potential adverse effects of medication.
Which conclusion is best supported by the findings in the study?
Methylphenidate shows an early response when added to behavior therapy is the correct answer. Attention-deficit/hyperactivity disorder is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity. The history must reveal that symptoms of inattention or hyperactivity and impulsivity are present in more than one setting, as symptoms may be absent when the patient is interacting in the clinician's office. Evidence-based behavior therapy should be prescribed as the first line of therapy for preschool-aged children, and stimulant medications may be prescribed for the preschooler with severe ADHD or inadequate response to behavior therapy.

Which of the following is not a reasonable recommendation to provide for the management of moderate to severe ADHD?
ADHD symptoms may be associated with artificial food additives in diet, so behavior therapy may be avoided by adhering to additive-free diet is the correct answer. Behavior therapy should be prescribed for all preschool-aged children as treatment for ADHD. Stimulant medications may be prescribed for moderate to severe ADHD and when behavior therapy fails to provide improvement in ADHD symptoms.

Lithium is a medication that is effective in the treatment of __________.
The manic and depressive phases of bipolar disorder can be treated with the mood stabilizer lithium. Lithium is used for the prevention of future depression and suicide and for the prevention of future mania. Schizophrenia is treated with antipsychotic medications. Medications to reduce nightmares, insomnia, and startle reactions are used in the treatment of post-traumatic stress disorder. Benzodiazepines and selective serotonin reuptake inhibitors (SSRIs) are used to treat panic disorders. SSRIs are also used to treat obsessive-compulsive disorder.

A patient goes to her primary care doctor complaining of mood swings affecting her in such a way that she often feels either very "high" or very "low." She denies any thoughts of worthlessness or of hurting herself, doesn't have trouble concentrating on tasks, and has no psychotic episodes when she is "low." When feeling "high," she has increased energy and happiness. Her symptoms are indicative of which of the following mood disorders?
Cyclothymic disorder is a mild form of bipolar disorder where a person mood swings over a period of years that go from mild depression to elevated mood and excitement.
Individuals with any form of bipolar disorder will most likely experience some psychotic episodes. During manic episodes, they will have delusions of grandeur, racing ideas and speech, distractibility and high-risk behaviors. They generally sleep and eat less often during these episodes as well. A patient with cyclothymic disorder lacks the vegetative symptoms associated with major depressive disorders. They can concentrate normally and lack both suicidal ideations and feelings of worthlessness when "low."

If a person is assaulted on the street of a large city in the middle of the day with many people around, the likelihood that someone will call for help will actually decrease in relation to the larger crowds. This phenomenon is known as which of the following?
According to the bystander effect, there is diffusion of responsibility; thus, most people assume, often mistakenly, that “someone else” will take the necessary actions such as calling the police or ambulance. The likelihood of someone taking appropriate action is inversely correlated with the number of people at the scene.
While intriguing, the other choices are incorrect. A self-serving bias is the tendency to attribute successes to ourselves and failures to external causes. Conformity is where one adjusts one’s thinking or behavior because of that of others. Deviance is described as a violation of society’s standards of conduct or expectations. Groupthink is a psychological phenomenon that occurs within a group of people, in which the desire for harmony or conformity in the group results in an irrational or dysfunctional decision-making outcome.

Diana takes the subway to and from school every day. Her family’s apartment, situated in a low-income neighborhood of New York City, is a thirty-minute walk from the subway station. During her trips to the subway, Diana loves to watch people work, play, and socialize. She feels very safe in her community because she trusts the people around her.
Diana sees a large man yelling at a woman. He shoves the woman and she tries to run away, but the man grabs her. Even though she is yelling, none of the other pedestrians pay any attention. Which of the following social terms describes the scene that Diana is observing?
Also called bystander apathy, the “bystander effect” describes cases where individuals do nothing to help someone in need when other people are around. Many think that if no one else is reacting, then it must mean that the problem is not worth solving. A landmark case occurred in New York when Kitty Genovese was stabbed to death in a public area. Although 38 people witnessed the murder, no one stepped in to help. This scenario is a classic example of the bystander effect. Although the people could be described as conforming to one another, bystander effect is a more specific description.

On a different occasion, Diana stumbles on a set of stairs and crashes towards the pavement. She reaches out to break her fall and feels a crackling sensation as her hand hits the ground. She finds a large scrape across her palm that does not completely heal for weeks. For months after this event, Diana feels anxious whenever she sees a set of stairs. In terms of classical conditioning, the sight of stairs would be described as which of the following?
When Diana sees a set of stairs, they act as a stimulus to induce anxiety. Since she did not feel this way before the accident, the sight of stairs would be a “conditioned stimulus.” Anxiety is the “conditioned response.” The initial stumble and injury would be the “unconditioned stimulus” and “response,” respectively.

Alice's dog is very anxious around cats; every time he sees one he whines. Alice began taking her dog for a walk every morning and passed the neighbor's house with cats that perched themselves on the windowsill. Her dog would whine until the cats were out of sight. Eventually, the cats disappeared from the windowsill; however, her dog continued to whine whenever he saw the neighbor's house.
In this example, what is the unconditioned stimulus (US), unconditioned response (UR), neutral stimulus (NS), conditioned stimulus (CS), and conditioned response (CR)?
The unconditioned stimulus is the cats and the unconditioned response is whining. This is because it is made clear that, from the beginning, the dog whines upon seeing cats. No conditioning has occurred to cause this behavior. The house represents the neutral stimulus, because it is being paired with the unconditioned stimulus (i.e. the cats). Walking past the house with the cats every morning represents the period of the dog's conditioning (i.e. he is repeatedly seeing the unconditioned stimulus paired with the neutral stimulus).
Eventually, the unconditioned stimulus (the cats) disappears. This is the period after conditioning, and if conditioned well, then the dog will continue to whine (which is now the conditioned response) when seeing the house (which is now the conditioned stimulus).
For comparison, Pavlov's dogs always salivated (unconditioned response) in response to seeing food (unconditioned stimulus). During the conditioning period, a neutral stimulus (a bell) was rung while showing the food to the dogs (i.e. the neutral stimulus is paired with the unconditioned stimulus). Following the conditioning period, the bell alone (no food) triggered salivation in the dogs. The bell became the conditioned stimulus and the salivation became the conditioned response.

Alice's dog hates vacuum cleaners. He has been conditioned to bark every time she opens the closet door, because usually this means she will begin vacuuming. She begins storing her shoes in the closet and keeps the vacuum in the basement; however, he continues to bark when she opens the closet door. Consider the given processes associated with the scenario.
Process A
If Alice continues to open the closet door without beginning to vacuum, then eventually the dog will stop barking.
Process B
If Alice then stops using the closet altogether for several months, and then suddenly opens it again, the dog will begin barking.
What are the two processes (A and B) that best describe this scenario?
The process of repeatedly seeing the conditioned stimulus (e.g., the opening of the closet door) without the unconditioned stimulus (e.g., vacuuming) is extinction. The dog has stopped associating the opening of the closet door with the frightening vacuum.
If the subject is not exposed to the conditioned stimulus (e.g. opening the closet door) for a period of time (e.g. several months, though this could be shorter or longer depending on the situation) and then is suddenly re-exposed to the conditioned stimulus, then spontaneous recovery can occur. The conditioned response suddenly occurs again when exposed to the conditioned stimulus. In this case, Alice opens the door several months later and the dog barks again. If she continues to open the door again, without using the vacuum, the extinction process will occur again.
“Acquisition” is the initial process of conditioning, during which the neutral stimulus (e.g. opening of the closet door) is paired with the unconditioned stimulus (e.g. vacuuming). “Generalization” is when similar stimuli to the conditioned stimulus trigger the conditioned response. For example, if the dog began barking when Alice opened any door. “Discrimination” is when only the specific conditioned stimulus triggers the conditioned response (i.e. only the opening of the closet door, not any other, door) elicits the barking.

Russian psychologist Ivan Pavlov extensively studied learning in animals. Most significantly, he contributed to the idea that is currently referred to as classical conditioning. Many know him from the popularly cited Pavlovian dog study from the greater experiment known as Lectures on the Function of the Principle Digestive Glands (1897).
In the Pavlovian dog experiment, Pavlov paired a neutral stimulus with a pleasurable one. The neutral stimulus was the ringing sound of a metronome, while the pleasurable stimulus was food. Pavlov never fed his dogs without ringing the metronome first, and as a result, his dogs would later salivate upon hearing the sound of the metronome. This learning process is known as conditioning, and this this specific instance, classical conditioning.
Later, Pavlov began ringing the metronome without feeding the dogs. As a result, the dogs eventually stopped salivating upon hearing the metronome. This is known as extinction. Finally, upon reintroducing the metronome/food pairing, the dogs quickly began salivating again, which is known as spontaneous recovery.
The passage describes classical conditioning, which of the following best describes the relationship between classical conditioning and operant conditioning.
Classical conditioning, as described in the passage, pairs a stimulus (e.g. the sound of a bell) with another behavior (e.g. receiving food). Eventually, according to the precepts of classical conditioning the bell will elicit a response (e.g. salivating in anticipation of receiving food). On the other hand, operant conditioning is a type of learning that is mediated by punishments and rewards/reinforcements. The punishment or reinforcement either encourages or discourages the learner from repeating a certain behavior.

Prior to feeding his hamster, a young boy flicks the side of the hamster's cage so that the hamster hears a "bang" noise. He does this every time before feeding the hamster. Based on the passage and the idea of generalization, what behavior can we expect the hamster to perform upon hearing someone knock on the cage, instead of flicking the cage?
According to the idea of generalization, a stimulus similar to the conditioned stimulus will elicit the conditioned response. If this hamster has generalized the stimulus, then he will recognize the knock on his cage as being similar (or the same) as the flick on his cage. As a result, we can expect the hamster to run to his food dish in anticipation of being fed. If the hamster ignored the stimulus, then that would be a good example of discrimination, not generalization. Additionally, while it is possible, we have no reason to believe that the hamster would become fearful or would run on his wheel based on the idea of generalization.

Based on the passage and the idea of discrimination, what behavior can we expect the hamster to perform upon hearing someone knock on the cage, instead of flicking the cage?
According to the idea of discrimination, a conditioned stimulus can be distinguished from other stimuli. If the hamster has been able to discriminate, then it is likely that he will ignore the knock on the cage, and recognize that the knock sound is not the same as a flick sound. On the other hand, if the hamster generalizes the stimulus, then he will respond to the knock in the same way that he responds to the flick, and run to his food dish. Based on the idea of discrimination_,_ we have no reason to expect the hamster to run on his wheel, or to try to escape in fear.
