Question 1

One of the phenotype's most salient aspects is increased rates of ______ and ______ behaviors.

Accepted Answer

Increased rates of internalizing and externalizing behaviors are key aspects of certain phenotypes, reflecting a broad categorization of problematic or symptomatic behaviors. Internalizing behaviors are directed inward and can include anxiety and depression, while externalizing behaviors are directed outward and can include aggression and defiance.

Question 2

______ refers to the processes by which certain genes are activated (or expressed) and thereby contribute to the production of the proteins necessary to build and sustain a person.

Accepted Answer

Genetic expression is the correct term for the processes by which genes are activated or expressed, leading to the production of proteins essential for building and sustaining a person.

Question 3

The hypothalamic-pituitary-adrenal (HPA) axis comprises the ______, ______, and ______.

Accepted Answer

The HPA axis is a complex set of direct influences and feedback interactions among the hypothalamus, the pituitary gland, and the adrenal glands. It is a major part of the neuroendocrine system that controls reactions to stress and regulates many body processes, including digestion, the immune system, mood and emotions, sexuality, and energy storage and expenditure.

Question 4

______ whether due to a flattened diurnal slope, elevated basal levels, or hyperreactivity can have adverse effects across a number of systems, inhibiting immune and cognitive function.

Accepted Answer

High levels of cortisol can lead to various adverse effects on the body, including impaired immune and cognitive functions. Cortisol is known as the stress hormone, and its elevated levels or abnormal patterns can negatively impact health.

Question 5

______ of activity in the amygdala were also reported in response to fearful faces for children who had been institutionalized and thus more likely to have experienced neglect.

Accepted Answer

Higher levels of activity in the amygdala are typically reported in response to fearful faces in children who have experienced neglect or trauma, such as those who have been institutionalized. This is because the amygdala plays a key role in processing emotions, including fear, and can become hypersensitive due to adverse experiences.

Question 6

What were the results of the epigenome-wide association studies of the genomes or genotypes of maltreated youth compared with genomes of children who were not maltreated?

Accepted Answer

Epigenome-wide association studies have shown that maltreated youth exhibit differences in methylation, particularly in introns, which play a significant role in the regulation of genetic expression. This suggests that maltreatment can lead to epigenetic changes that may affect gene expression and potentially influence development and health outcomes.

Question 7

One measure that more effectively isolates the activity of the PNS is ______.

Accepted Answer

Respiratory Sinus Arrhythmia (RSA) is a measure that effectively isolates the activity of the Parasympathetic Nervous System (PNS). It refers to the natural increase in heart rate that occurs during inhalation and the decrease in heart rate that occurs during exhalation, which is mediated by the PNS.

Question 8

______ are certain areas of the brain, including the fusiform gyrus and superior temporal sulcus, that monitor for environmental threats.

Accepted Answer

The answer of ______ are certain areas of the brain,...

Question 9

In the broadest sense, it is the ______ that aggregates and processes our sensory experiences of the environment and thereby shapes and modulates the activity of "lower level" systems such as the ANS and HPA axis to fit that environment.

Accepted Answer

The brain aggregates and processes our sensory experiences of the environment, influencing the activity of systems like the ANS (Autonomic Nervous System) and HPA (Hypothalamic-Pituitary-Adrenal) axis to adapt to environmental demands.

Question 10

A number of studies have examined whether aggressive and withdrawn behaviors can be linked to maltreatment's effects at the level of the endophenotype, with different investigators focusing on the autonomic nervous system, HPA axis, and brain.The common question in these studies is ______?

Accepted Answer

The common question in these studies is whether the effects of maltreatment on the phenotype (observable characteristics or behaviors) are mediated by its effects on the endophenotype (biological or genetic processes underlying these characteristics or behaviors).

Question 11

The autonomic (ANS) is divided into two branches ______ and ______.

Accepted Answer

The autonomic nervous system (ANS) is divided into two main branches: the parasympathetic nervous system and the sympathetic nervous system. These two branches work together to maintain homeostasis in the body by controlling involuntary bodily functions such as heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.

Question 12

______ is an aspect of the environment that leads to "strong, frequent, or prolonged activation of the body's stress management system."

Accepted Answer

A toxic stressor is defined as an aspect of the environment that leads to strong, frequent, or prolonged activation of the body's stress management system. This type of stress can have significant negative impacts on health and development.

Question 13

What are the two ways brain activity can be monitored?

Accepted Answer

Functional magnetic resonance imaging (fMRI) and event-related potentials (ERPs) are two methods used to monitor brain activity. fMRI measures brain activity by detecting changes associated with blood flow, while ERPs are derived from electroencephalography (EEG) and measure brain response to specific sensory, cognitive, or motor events.

Question 14

While internalizing and externalizing may be protective in the short term, over the long term these could be ______?

Accepted Answer

The answer of While internalizing and externalizing may be protective...

Question 15

The mixed findings regarding maltreatment and the function of the ANS can be explained using the principle of ______.

Accepted Answer

Allostasis explains the mixed findings regarding maltreatment and the function of the ANS by describing how the body responds to stress through changes in physiological systems to maintain stability through change, rather than maintaining a constant internal environment as suggested by homeostasis. This concept accounts for the variability in ANS responses to maltreatment.

Question 16

Please discuss three different areas the authors point to as directions for future research.

Accepted Answer

The answer of Please discuss three different areas the authors...

Question 17

______ refers to the continuous and largely involuntary process of monitoring the environment for threats.

Accepted Answer

Neuroception refers to the process by which the nervous system evaluates risk in the environment without conscious thought, helping to identify threats for protective responses.

Question 18

Please explain the two different ways that brain activity can be monitored as discussed in the chapter.

Accepted Answer

The answer of Please explain the two different ways that...

Question 19

In Gottlieb's formulation of biodirectional influence, he indicated that ______ occupies the space between the genotype and phenotype.

Accepted Answer

Gottlieb's formulation of bidirectional influence suggests that neural activity is the intermediary process that occupies the space between the genotype (an organism's genetic makeup) and phenotype (the observable characteristics or traits of an organism). This emphasizes the role of neural processes in the expression of genetic information into observable traits.

Question 20

The association between maltreatment and hyporeactivity in response to stress ______.

Accepted Answer

The association between maltreatment and hyporeactivity in response to stress does not imply causation. It indicates a correlation, but other factors could contribute to this relationship, and causation cannot be assumed without further evidence.
