the failure to become aware of stimuli that one is physically capable of sensing is called:
The failure to become aware of stimuli that one is physically capable of sensing is called sensory neglect or inattentional blindness.
This phenomenon occurs when our attention is focused on one particular task or stimulus, causing us to miss other stimuli that are present. Our brains are constantly processing large amounts of information, and when we are not actively attending to a particular sensation, our brain may not register it. For example, if we are focused on a conversation, we may not notice a car honking outside. This phenomenon is common and can be useful in certain situations, but it can also be dangerous if it leads to a failure to detect important information. It is important to remain vigilant and actively engage in our surroundings to avoid sensory neglect.

attitudes are comprised of three dimensions: cognition, affect, and _______.
Attitudes are comprised of three dimensions: cognition, affect, and conation. The conation dimension refers to the behavioral component of attitudes, which encompasses an individual's tendency to act or behave in a particular way based on their attitude.
It represents the behavioral intentions or actions that arise from one's attitudes and beliefs. The conation dimension reflects the link between attitudes and behavior.
While cognition involves the beliefs, thoughts, and knowledge individuals hold about an object, and affect refers to the emotional or evaluative component of attitudes, conation focuses on the behavioral aspect. It encompasses the actions, intentions, and behaviors that result from the cognitive and affective components of attitudes.
Understanding the conation dimension is crucial because it helps explain how attitudes influence behavior. Attitudes alone may not always lead to behavioral outcomes, as various factors can mediate the translation of attitudes into actions. The conation dimension bridges the gap between attitudes and behavior, shedding light on the active component of attitudes that propels individuals to act in accordance with their attitudes or intentions.

norms that guide everyday casual interactions. violators are sanctioned subtly or not at all. (example: making out- deep kissing- with a partner in some public places is frowned upon)
Norms that guide everyday casual interactions and are subtly or not at all sanctioned when violated are known as folkways.
Folkways are informal social norms that govern customary behaviors and etiquette in society. These norms are often specific to particular cultural or social groups and can vary across different contexts. Unlike more formal norms, such as laws or legal regulations, the violation of folkways typically results in mild disapproval, social discomfort, or informal sanctions rather than severe consequences. Examples of folkways include appropriate dress codes for specific occasions, greetings and gestures, table manners, or public displays of affection. While making out or deep kissing in some public places may not be explicitly prohibited by laws, it is often considered a violation of social norms and can lead to disapproving glances, comments, or other subtle forms of social pressure. Folkways play a role in maintaining social order, harmony, and cultural expectations within a community or society.

_________ see personality as nothing more than a set of learned responses.
Behaviorists see personality as nothing more than a set of learned responses.
Behaviorists, as a psychological perspective, emphasize the role of environmental factors and learning experiences in shaping and determining personality. According to behaviorism, personality is viewed as a result of conditioning processes, where individuals acquire specific behaviors through the reinforcement and punishment of their actions.
Behaviorists reject the notion of innate or unconscious influences on personality and instead focus on observable behaviors and the environmental contingencies that shape them. They believe that personality can be understood and modified through the study and manipulation of environmental stimuli and behavioral responses. In this perspective, personality is seen as a product of external influences rather than inherent traits or characteristics.

What should be used first when dealing with problem behaviors?
When dealing with problem behaviors, it is important to use positive reinforcement techniques first. Positive reinforcement is a technique that involves rewarding desirable behaviors in order to encourage their repetition. This technique has been found to be particularly effective in modifying behavior in children, adolescents, and adults.
Positive reinforcement can be used in a variety of ways, such as offering praise, providing tangible rewards, or giving privileges. The key is to find a reward that is meaningful to the individual and that they will be motivated to work for. For example, a child who loves video games may be motivated to complete their homework by being offered extra screen time. Alternatively, a teenager who loves sports may be motivated to clean their room by being offered a ticket to a game. Using positive reinforcement has several advantages. Firstly, it helps to build positive relationships between the individual and their caregiver or teacher. This is because positive reinforcement techniques focus on praising and rewarding good behavior rather than punishing bad behavior. This positive approach is more likely to be perceived as fair and respectful, which can help to reduce conflicts and build trust.
Secondly, positive reinforcement can be used to teach new behaviors or skills. For example, if a child is having difficulty sharing with others, positive reinforcement can be used to encourage them to take turns and share their toys. Over time, this positive reinforcement will help the child to learn new social skills and become more cooperative.
Finally, positive reinforcement can be used to maintain good behavior. By providing rewards for good behavior, individuals are more likely to continue behaving in the desired way. This can help to prevent relapse into problem behaviors and promote long-term behavior change.

suppose you are reading a novel and gradually fall asleep and begin to dream . how would your brain waves change during this sequence of events ?
Initially, the brain enters a relaxed state characterized by alpha waves, followed by theta and delta waves, during deep sleep and rapid eye movement (REM) sleep.
As you start to fall asleep while reading, your brain waves transition from a state of wakefulness, characterized by beta waves, to a more relaxed state. This relaxed state is associated with alpha waves, which indicate a relaxed and drowsy state of mind. Alpha waves are typically observed when the eyes are closed, and the mind begins to disengage from the external environment.
During the transition from drowsiness to deeper sleep, the brain waves shift further. As you enter non-rapid eye movement (NREM) sleep, your brain activity slows down, and slower waveforms become prominent. Theta waves, which are slower and more synchronized than alpha waves, start to dominate during the early stages of NREM sleep. Theta waves are associated with light sleep and the early phases of dreaming.
As sleep deepens, the brain enters stages of NREM sleep where slower and more synchronized delta waves prevail. Delta waves are the slowest brain waves and are associated with deep sleep and restorative processes. During this stage, the brain is less responsive to external stimuli.
Finally, during REM sleep, which is the stage associated with vivid dreaming, brain activity becomes more active and resembles wakefulness. Rapid eye movements occur during this stage, and the brain exhibits a mix of beta and theta waves. These waves are similar to those observed when you are awake and actively engaged in mental processes, possibly reflecting the intense and immersive nature of dreaming.
As you fall asleep while reading a novel and transition into dreaming, your brain waves change. Initially, alpha waves signify a relaxed state. Then, theta waves become prominent during the early stages of sleep, followed by slower delta waves during deep sleep. During REM sleep, brain activity increases, resembling wakefulness with a mix of beta and theta waves. These changes in brain waves reflect the different stages of sleep and dreaming processes.

Option B is the most nearly correct statement because the Student's t distribution is used when the population standard deviation is unknown. The t distribution takes into account the uncertainty introduced by estimating the standard deviation from the sample data.
a. Option A states that we should use z instead of t when n is large. This statement is incorrect because when the sample size (n) is large, the sample mean tends to follow a normal distribution, and the standard deviation of the sample mean can be estimated using the population standard deviation (σ). In such cases, the z-distribution is appropriate. The t-distribution is used when the population standard deviation is unknown or when the sample size is small.
b.Option B is the closest to being right. When the population standard deviation (σ) is unknown, the Student's t distribution is employed.
This distribution accounts for the additional uncertainty introduced by estimating the standard deviation from the sample data. When the sample size is small, the t-distribution is more appropriate than the z-distribution.
c. Option C states that using the Student's t distribution instead of z narrows the confidence interval. This statement is incorrect. In reality, using the t-distribution instead of the z-distribution widens the confidence interval.
The t-distribution has fatter tails compared to the z-distribution, which reflects the increased uncertainty associated with estimating the population standard deviation from a small sample size. As a result, the confidence interval tends to be wider to accommodate this additional uncertainty.

The probable question may be:
Concerning confidence intervals, which statement is most nearly correct? Why not the others?
a. We should use z instead of t when n is large.
b. We use the Student’s t distribution when is unknown.
c. Using the Student’s t distribution instead of z narrows the confidence interval.
what is one reason contemporary mothers might be unlikely to give their children up for adoption?
Contemporary mothers may be unlikely to give their children up for adoption due to the stigma and negative perception surrounding adoption.
Historically, adoption was viewed as a last resort for unmarried and teenage mothers who were unable to provide for their children. This societal perception has led to a belief that adoption is a failure on the part of the mother to fulfill her maternal responsibilities. Additionally, the idea of giving up a child for adoption can be emotionally and psychologically taxing on the mother, which may discourage her from pursuing this option. With the availability of resources such as childcare, financial assistance, and counseling, contemporary mothers may feel empowered to make the decision to raise their child on their own.
Furthermore, the increase in open adoption options allows mothers to maintain a relationship with their child while also providing them with a stable and loving family. Overall, the negative stigma surrounding adoption and the emotional burden associated with giving up a child are reasons contemporary mothers may be unlikely to pursue this option.
