Question 1

1. Identity vs. role confusion: adolescence focuses on exploring roles and values, forming identity or experiencing confusion about self.
2. Intimacy vs. isolation: young adulthood requires forming close, committed bonds; avoidance can lead to isolation and loneliness. (correct answer)
3. Generativity vs. stagnation: midlife focuses on contributing to society and the next generation through mentoring and productivity.
4. Trust vs. mistrust: infancy centers on learning caregiver reliability, shaping basic expectations about safety and dependability.

Explanation: This scenario illustrates an unresolved intimacy vs. isolation crisis from Erikson's theory, which occurs during young adulthood (ages 20-40). The 30-year-old's avoidance of close relationships and resulting loneliness, combined with fear of dependence, indicates difficulty forming the intimate bonds that are central to this developmental stage. During this period, individuals who have successfully resolved their identity crisis in adolescence are ready to form committed, intimate relationships with others. Those who struggle with intimacy may experience isolation and loneliness, often due to fears of losing their independence or being hurt in close relationships. The fear of dependence suggests that this person may be protecting their autonomy at the expense of meaningful connection. This differs from identity vs. role confusion (adolescent self-concept formation), generativity vs. stagnation (midlife contribution to society), and trust vs. mistrust (infant caregiver relationships). The emphasis on romantic and friendship relationships and the struggle with emotional closeness characterizes this stage.

Question 2

1. Conventional morality: behavior focuses on pleasing others and obeying laws to maintain social order and avoid disapproval from authority.
2. Preconventional morality: behavior is guided by avoiding punishment and seeking rewards, with limited concern for broader principles.
3. Postconventional morality: reasoning appeals to universal ethical principles and individual rights, sometimes prioritizing them over laws. (correct answer)
4. Preconventional morality: behavior is guided by group loyalty, prioritizing approval from friends and family over abstract principles.

Explanation: This statement reflects postconventional morality, specifically Stage 6 (universal ethical principles) in Kohlberg's theory. At this highest level of moral development, individuals make decisions based on universal ethical principles such as justice, human rights, and dignity, even when these principles conflict with laws or social expectations. The person's willingness to break "an unjust law to protect human rights" demonstrates moral reasoning that transcends legal and social conventions to focus on abstract ethical principles. This level of moral reasoning is relatively rare and represents the most sophisticated form of moral thinking. It differs from preconventional morality (focused on personal consequences) and conventional morality (focused on social approval and law adherence). Postconventional thinkers recognize that laws are social contracts that should serve justice and human welfare, and they may engage in civil disobedience when laws conflict with fundamental human rights.

Question 3

1. Preconventional morality: rule-following is based on avoiding punishment, with little concern for others' expectations or social approval.
2. Conventional morality: reasoning centers on social approval and meeting expectations of authority figures or groups to be seen as good. (correct answer)
3. Postconventional morality: rules are evaluated by universal principles, and expectations are secondary to justice and human rights.
4. Postconventional morality: reasoning centers on gaining rewards and avoiding costs, treating morality as a personal trade-off calculation.

Explanation: This reasoning exemplifies conventional morality, specifically Stage 3 (interpersonal conformity) in Kohlberg's theory. At this level, moral decisions are guided by the desire to maintain approval from others and meet social expectations, particularly those of authority figures and respected groups. The child's concern about disappointing teachers demonstrates that their moral reasoning is based on maintaining positive relationships and gaining approval rather than on abstract principles or fear of punishment. This represents moral development beyond preconventional thinking (which focuses on personal consequences) but has not yet reached postconventional reasoning (which emphasizes universal ethical principles). The focus on others' expectations and emotional reactions (disappointment) rather than rules themselves indicates Stage 3 reasoning. This type of moral thinking is common during late childhood and adolescence when peer and authority approval becomes increasingly important for self-concept and social belonging.

Question 4

1. Permissive parenting: warm and accepting but provides few rules or expectations, rarely using consistent consequences for misbehavior.
2. Uninvolved parenting: low warmth and low control, offering minimal supervision, guidance, or emotional involvement in daily life.
3. Authoritarian parenting: high control and low warmth, emphasizing obedience, strict discipline, and limited negotiation or explanation. (correct answer)
4. Authoritative parenting: warm, responsive, and firm, using reasoning and consistent limits while encouraging independence and dialogue.

Explanation: This scenario describes authoritarian parenting, characterized by high control and low warmth. Authoritarian parents enforce strict rules with little explanation, expect immediate obedience, and use punishment rather than reasoning to manage behavior. They show minimal warmth or emotional responsiveness and rarely engage in discussion or negotiation with their children. This parenting style emphasizes respect for authority, order, and tradition, often at the expense of the child's autonomy and emotional needs. While children of authoritarian parents may be well-behaved and achieve academically, they often struggle with self-esteem, decision-making, and emotional expression. This contrasts with authoritative parenting (high warmth and control with reasoning), permissive parenting (high warmth but low control), and uninvolved parenting (low warmth and control). The key characteristics here are the strict rule enforcement, expectation of obedience without question, and lack of warmth or discussion.

Question 5

1. Secure attachment: infant seeks contact at reunion and is soothed quickly, returning to play and exploration after brief comfort.
2. Insecure-avoidant attachment: infant shows minimal distress and avoids caregiver at reunion, not seeking comfort or proximity.
3. Insecure-anxious/ambivalent attachment: infant shows intense distress and remains difficult to soothe, mixing clinging with resistance. (correct answer)
4. Disorganized attachment: infant shows contradictory or fearful behaviors, such as freezing, without a consistent reunion response pattern.

Explanation: This behavior describes insecure-anxious/ambivalent attachment in the Strange Situation. Children with this attachment style experience intense distress during separation and remain difficult to soothe even after the caregiver returns. The infant's extreme distress and inability to be comforted reflects the core characteristics of anxious-ambivalent attachment: high anxiety about caregiver availability and difficulty regulating emotions even when comfort is offered. This attachment style typically develops when caregiving is inconsistent—sometimes responsive and sometimes not—leaving the child uncertain about whether their needs will be met. The child's continued distress after reunion reflects their internal working model that caregivers are unreliable, even when physically present. This differs from secure attachment (quick soothing and return to exploration), avoidant attachment (minimal distress and caregiver avoidance), and disorganized attachment (contradictory or fearful behaviors). The key indicator is the intense distress that persists despite the caregiver's presence and attempts at comfort.

Question 6

1. Conventional morality: emphasizes being a good student and maintaining school rules to support social order and community expectations.
2. Postconventional morality: emphasizes fairness and rights, rejecting cheating because it violates ethical principles regardless of outcomes.
3. Preconventional morality: emphasizes self-interest and personal gain, judging actions by rewards and benefits to oneself. (correct answer)
4. Conventional morality: emphasizes fear of punishment, avoiding cheating only because teachers might catch and penalize the student.

Explanation: This reasoning reflects preconventional morality, specifically Stage 2 (instrumental exchange) in Kohlberg's theory. At this level, moral decisions are based on self-interest and personal gain, with individuals viewing moral behavior through the lens of "what's in it for me." The student's acceptance of cheating to obtain a scholarship demonstrates reasoning focused on personal benefits rather than broader ethical principles, social expectations, or concern for fairness to others. This represents a somewhat more sophisticated form of preconventional thinking than Stage 1 (which focuses purely on avoiding punishment) because it involves calculating trade-offs and future benefits. However, it still centers on self-interest rather than considering the impact on others or broader social values. This differs from conventional morality (which would consider social disapproval and rules) and postconventional morality (which would reject cheating based on universal principles of fairness and integrity).

Question 7

1. Secure attachment: infant explores actively with caregiver as safe base, shows moderate distress, and is soothed quickly at reunion.
2. Insecure-anxious/ambivalent attachment: infant shows clinginess, limited exploration, strong separation distress, and difficulty calming at reunion. (correct answer)
3. Insecure-avoidant attachment: infant explores without referencing caregiver, shows minimal distress, and avoids contact at reunion.
4. Disorganized attachment: infant displays freezing or contradictory behaviors, such as approaching while looking fearful or confused.

Explanation: This behavior pattern describes insecure-anxious/ambivalent attachment in the Strange Situation. Children with this attachment style show excessive anxiety about caregiver availability, which manifests as staying close to the caregiver, limited exploration of the environment, and extreme distress at separation. The infant's reluctance to explore, tendency to stay near the caregiver, and high level of separation distress all indicate an insecure attachment where the child cannot use the caregiver as a secure base for exploration. This attachment style typically develops when caregiving is inconsistent—sometimes responsive, sometimes not—leaving the child uncertain about caregiver availability and anxiously vigilant about maintaining proximity. It differs from secure attachment (confident exploration with caregiver as safe base), avoidant attachment (independent exploration with minimal separation distress), and disorganized attachment (contradictory or fearful behaviors). The combination of limited exploration, proximity-seeking, and intense separation anxiety are hallmarks of anxious-ambivalent attachment.

Question 8

1. Industry vs. inferiority: school-age children compare competence with peers, developing confidence through mastery or inferiority after failure. (correct answer)
2. Autonomy vs. shame and doubt: toddlers develop independence in self-care, feeling shame when caregivers restrict exploration and choices.
3. Intimacy vs. isolation: young adults form committed relationships, risking loneliness and isolation when they avoid closeness.
4. Integrity vs. despair: older adults evaluate life achievements, feeling acceptance or despair about missed opportunities and regrets.

Explanation: This scenario illustrates a negative resolution of Erikson's industry vs. inferiority crisis, which occurs during middle childhood (ages 6-11). During this stage, children focus on developing competence in academic skills, sports, and other culturally valued activities, often comparing their performance to that of their peers. The 12-year-old's feelings of inferiority after repeated difficulty in math compared to classmates demonstrates the potential negative outcome of this stage. When children consistently experience failure or perceive themselves as less competent than their peers, they may develop a sense of inferiority that can persist and affect their self-concept and motivation. This crisis emphasizes the importance of providing children with opportunities for success and recognizing their unique strengths while helping them develop skills in areas where they struggle. This differs from earlier stages like initiative vs. guilt (preschool planning and leadership) and later stages like identity vs. role confusion (adolescent self-concept formation). The focus on academic competence and peer comparison is characteristic of this developmental period.

Question 9

1. Insecure-avoidant attachment: infant shows little separation distress and avoids caregiver at reunion, appearing indifferent and not seeking comfort. (correct answer)
2. Secure attachment: infant shows separation distress and seeks contact at reunion, quickly calming and returning to exploration.
3. Insecure-anxious/ambivalent attachment: infant becomes extremely distressed and is difficult to soothe, showing clingy and resistant reunion behavior.
4. Disorganized attachment: infant exhibits fearful, contradictory, or disoriented behaviors at reunion, lacking a consistent coping strategy.

Explanation: This behavior pattern describes insecure-avoidant attachment in the Strange Situation. Children with avoidant attachment have learned to suppress their attachment behaviors and appear independent and self-reliant. The infant's lack of distress at separation and ignoring behavior at reunion reflects an adaptive strategy developed in response to caregiving that is emotionally unavailable or rejecting of attachment needs. While these children appear unaffected by separation, research shows they experience internal stress but have learned that seeking comfort may lead to rejection. This attachment style often results from caregivers who are consistently unresponsive to emotional needs or who actively discourage attachment behaviors. It differs from secure attachment (appropriate distress and comfort-seeking), anxious-ambivalent attachment (extreme distress and conflicted reunion behavior), and disorganized attachment (contradictory or fearful behaviors). The key indicators are the minimal separation distress and consistent avoidance of caregiver contact at reunion.

Question 10

1. Identity vs. role confusion: adolescents explore values and roles, aiming to develop a coherent sense of self and future direction. (correct answer)
2. Intimacy vs. isolation: young adults seek committed relationships and close bonds, struggling with loneliness when connections feel unsafe.
3. Industry vs. inferiority: school-age children compare competence to peers, building confidence through mastery of academic and social skills.
4. Generativity vs. stagnation: midlife adults focus on contributing to society and guiding the next generation through work and caregiving.

Explanation: This scenario illustrates Erikson's identity vs. role confusion crisis, which occurs during adolescence (approximately ages 12-18). During this stage, teenagers explore different roles, values, and beliefs to develop a coherent sense of self and future direction. The 16-year-old's behavior of trying different friend groups and career ideas represents the healthy exploration necessary for identity formation. Successfully resolving this crisis leads to a strong sense of identity, while failure results in role confusion and uncertainty about one's place in society. This differs from other Erikson stages: industry vs. inferiority focuses on competence in school-age children, intimacy vs. isolation involves forming close relationships in young adulthood, and generativity vs. stagnation concerns contributing to society in midlife.

Question 11

1. Secure attachment: infant seeks proximity at reunion and calms quickly, returning to play with caregiver as a safe base.
2. Insecure-anxious/ambivalent attachment: infant clings and resists at reunion, remaining highly distressed and hard to soothe.
3. Insecure-avoidant attachment: infant avoids caregiver at reunion, limiting contact-seeking even when distressed, showing emotional distancing. (correct answer)
4. Disorganized attachment: infant shows fearful, confused, or contradictory behaviors at reunion, lacking a consistent approach strategy.

Explanation: This behavior describes insecure-avoidant attachment in the Strange Situation. The pattern of crying at separation but then turning away and avoiding contact at reunion is characteristic of children who have developed an avoidant attachment style. These children have learned to suppress their attachment behaviors because seeking comfort has previously been met with rejection or inconsistent responses. The crying at separation shows that the child does experience distress and has formed an attachment bond, but the avoidance at reunion represents an adaptive strategy to cope with anticipated rejection. This emotional distancing protects the child from further hurt but also prevents them from receiving comfort when it might be offered. This differs from secure attachment (seeking and accepting comfort), anxious-ambivalent attachment (clinging yet resisting comfort), and disorganized attachment (contradictory or fearful behaviors). The key pattern is the combination of separation distress with reunion avoidance, indicating suppressed attachment needs rather than absence of attachment.

Question 12

1. Integrity vs. despair: late adulthood involves evaluating one's life, achieving acceptance and meaning or feeling regret and bitterness. (correct answer)
2. Generativity vs. stagnation: midlife adults focus on productivity and supporting others, or feel self-absorbed and unproductive.
3. Intimacy vs. isolation: young adults seek close relationships and commitment, or experience loneliness and emotional distance.
4. Trust vs. mistrust: infancy centers on reliable caregiving to build security, or inconsistent care leading to suspicion and fear.

Explanation: This scenario illustrates successful resolution of Erikson's integrity vs. despair crisis, which occurs in late adulthood (65+ years). During this final stage of psychosocial development, individuals reflect on their lives and evaluate their accomplishments, relationships, and choices. Those who feel satisfied with their life choices and can accept both successes and failures develop ego integrity—a sense of wholeness and acceptance of their life as it was lived. The 70-year-old's satisfaction and acceptance rather than regret indicates successful navigation of this crisis. Failure to resolve this stage results in despair, bitterness, and regret over missed opportunities. This differs from earlier stages like generativity vs. stagnation (midlife focus on contributing to others), intimacy vs. isolation (young adult focus on relationships), and trust vs. mistrust (infant focus on caregiver reliability).

Question 13

1. Disorganized attachment: reunion behavior is confused or fearful, including freezing or contradictory actions without a consistent strategy.
2. Secure attachment: infant seeks caregiver at reunion and is soothed quickly, returning to play and exploration with confidence.
3. Insecure-anxious/ambivalent attachment: infant shows intense distress and ambivalent reunion behavior, both seeking and resisting comfort. (correct answer)
4. Insecure-avoidant attachment: infant shows minimal distress and avoids caregiver at reunion, acting indifferent and self-reliant.

Explanation: This behavior pattern describes insecure-anxious/ambivalent attachment in the Strange Situation. Children with this attachment style experience intense separation anxiety and show conflicted behavior at reunion, simultaneously seeking contact with the caregiver while also resisting comfort and remaining difficult to soothe. This pattern typically develops when caregiving is inconsistent—sometimes responsive and sometimes not—leading the child to be uncertain about the caregiver's availability. The child's extreme distress followed by clingy yet resistant behavior reflects their internal conflict between needing comfort and fearing rejection. This differs from secure attachment (quick soothing and return to play), avoidant attachment (minimal distress and avoidance), and disorganized attachment (contradictory or fearful behaviors). The key indicators are the intensity of distress and the ambivalent reunion behavior that combines approach and resistance.

Question 14

1. Autonomy vs. shame and doubt: toddlers develop independence in basic tasks, risking shame when caregivers are overly controlling or critical.
2. Initiative vs. guilt: preschoolers plan activities and assert power through play, feeling guilt when efforts are harshly discouraged. (correct answer)
3. Trust vs. mistrust: infants learn whether caregivers reliably meet needs, shaping expectations about safety and dependability in relationships.
4. Industry vs. inferiority: school-age children seek competence through achievement, feeling inferior when they cannot meet performance standards.

Explanation: This scenario illustrates Erikson's initiative vs. guilt crisis, which occurs during the preschool years (ages 3-5). During this stage, children begin to assert their independence by planning activities, making plans, and taking on leadership roles in play. The 3-year-old's insistence on doing things independently and subsequent guilt after being scolded demonstrates the central conflict of this stage. Successful resolution leads to a sense of initiative and confidence in one's ability to lead and make decisions, while failure results in guilt and reluctance to try new things. This differs from autonomy vs. shame and doubt (toddler focus on basic independence), industry vs. inferiority (school-age focus on competence), and trust vs. mistrust (infant focus on caregiver reliability). The key indicator here is the child's planning and leadership behaviors combined with guilt from criticism.

Question 15

1. Intimacy vs. isolation: young adults seek close, committed relationships and mutual sharing, risking loneliness if intimacy feels unsafe. (correct answer)
2. Identity vs. role confusion: adolescents explore roles and values to develop a coherent identity and sense of direction.
3. Generativity vs. stagnation: midlife adults focus on contributing to the next generation through work, mentoring, and caregiving.
4. Industry vs. inferiority: school-age children strive for competence in academics and skills, comparing achievements with peers.

Explanation: This scenario illustrates Erikson's intimacy vs. isolation crisis, which occurs during young adulthood (ages 20-40). During this stage, individuals focus on forming intimate, loving relationships with others, including romantic partnerships and close friendships. The 25-year-old's prioritization of forming a committed romantic partnership and fear of being alone demonstrates the central challenge of this stage. Successful resolution leads to the ability to form close, committed relationships and experience love and intimacy, while failure results in feelings of isolation and loneliness. This stage builds on the identity formation of adolescence—individuals need a clear sense of self before they can successfully merge their identity with another in intimate relationships. This differs from identity vs. role confusion (adolescent focus on self-concept), generativity vs. stagnation (midlife focus on contributing to society), and industry vs. inferiority (childhood focus on competence). The emphasis on romantic partnership and fear of loneliness are key indicators of this stage.

Question 16

1. Permissive parenting: high warmth with low demands, offering few firm limits and inconsistent discipline, often prioritizing child freedom. (correct answer)
2. Authoritarian parenting: strict rules with low warmth, expecting obedience and using punishment, with minimal negotiation or explanation.
3. Authoritative parenting: warm but firm, setting clear expectations and consistent consequences while encouraging independence and discussion.
4. Uninvolved parenting: detached and unresponsive, providing little guidance or affection and minimal monitoring of the child's behavior.

Explanation: This scenario describes permissive parenting, characterized by high warmth and affection combined with low demands and minimal rule enforcement. Permissive parents are emotionally supportive and nurturing but struggle to set and maintain consistent boundaries. They often avoid confrontation and allow children to make decisions that may not be developmentally appropriate, such as determining their own bedtime and screen time limits. While these parents mean well and maintain close emotional relationships with their children, the lack of structure can lead to difficulties with self-regulation and behavior problems. This contrasts with authoritative parenting (high warmth and high structure), authoritarian parenting (low warmth and high control), and uninvolved parenting (low warmth and low control). Children of permissive parents often struggle with self-discipline and may have difficulty respecting authority figures outside the home.

Question 17

1. Insecure-avoidant attachment: infant avoids caregiver at reunion and shows minimal distress, appearing emotionally distant and self-reliant.
2. Disorganized attachment: infant displays confused, contradictory, or apprehensive behaviors, suggesting a breakdown of organized attachment strategies. (correct answer)
3. Secure attachment: infant seeks comfort at reunion and is soothed quickly, then resumes exploration using caregiver as safe base.
4. Insecure-anxious/ambivalent attachment: infant clings and resists at reunion, remaining distressed and highly dependent on caregiver contact.

Explanation: This behavior pattern describes disorganized attachment in the Strange Situation. Disorganized attachment is characterized by the absence of a consistent strategy for dealing with separation and reunion, resulting in confused, contradictory, or dazed behaviors. Children with this attachment style may freeze, show fear of the caregiver, or display conflicting behaviors like approaching and retreating simultaneously. The lack of a consistent reunion pattern and dazed behavior indicates that the child cannot organize a coherent response to the caregiver's return. This attachment style often results from frightening or severely inconsistent caregiving, sometimes involving trauma or abuse. It differs from the three organized attachment styles (secure, avoidant, and anxious-ambivalent) which all show predictable patterns of behavior. Disorganized attachment is associated with increased risk for behavioral problems, emotional dysregulation, and difficulties in later relationships. It represents a breakdown in the attachment system's ability to provide comfort and security.

Question 18

1. Preconventional morality: rule-following is driven by avoiding punishment and immediate consequences, rather than internalized standards. (correct answer)
2. Conventional morality: rule-following is driven by maintaining social order and meeting expectations, even without supervision.
3. Postconventional morality: rule-following is driven by universal principles and rights, with laws evaluated against ethical standards.
4. Conventional morality: rule-following is driven by personal gain calculations, weighing rewards and costs to maximize benefits.

Explanation: This reasoning exemplifies preconventional morality, specifically Stage 1 (punishment and obedience orientation) in Kohlberg's theory. At this level, moral behavior is driven primarily by the desire to avoid punishment and the presence of authority figures who can impose consequences. The child's rule-following only when adults are watching demonstrates that their moral reasoning is based on external control rather than internalized values or social expectations. This represents the most basic level of moral development, where right and wrong are determined by whether behavior will be detected and punished. This differs from conventional morality, where individuals follow rules to gain approval or maintain social order even without supervision, and postconventional morality, where behavior is guided by universal principles regardless of external monitoring. The key indicator is the conditional nature of the rule-following—it depends entirely on the presence of authority figures who might impose consequences.

Question 19

1. Disorganized attachment: infant displays confused, contradictory, or fearful behaviors at reunion, suggesting no coherent strategy for comfort. (correct answer)
2. Insecure-avoidant attachment: infant avoids caregiver at reunion and shows minimal distress, appearing indifferent to separation and return.
3. Secure attachment: infant seeks proximity and is soothed quickly at reunion, then returns to exploring the environment comfortably.
4. Insecure-anxious/ambivalent attachment: infant clings and resists comfort at reunion, remaining highly distressed and difficult to soothe.

Explanation: This behavior pattern describes disorganized attachment, also known as disoriented attachment, in the Strange Situation. Children with this attachment style display contradictory, confused, or fearful behaviors at reunion, such as approaching the caregiver while simultaneously showing fear or suddenly freezing and backing away. This pattern suggests a breakdown in organized attachment strategies and often results from caregiving that is frightening or severely inconsistent, sometimes involving abuse or trauma. The infant's approach followed by freezing and fearful backing away indicates they are caught between their biological drive to seek comfort and their fear of the caregiver. This differs from the three organized attachment styles: secure (consistent comfort-seeking), avoidant (consistent avoidance), and anxious-ambivalent (consistent but conflicted approach). Disorganized attachment is associated with increased risk for behavioral and emotional problems later in development.

Question 20

1. Trust vs. mistrust: infants develop basic trust when caregivers reliably meet needs, forming expectations that the world is safe. (correct answer)
2. Autonomy vs. shame and doubt: toddlers build independence in self-care, developing confidence when caregivers encourage choice-making.
3. Initiative vs. guilt: preschoolers plan activities and take leadership in play, feeling guilt when adults criticize their efforts.
4. Industry vs. inferiority: school-age children gain competence through achievement and peer comparison, building confidence in skills.

Explanation: This scenario illustrates successful resolution of Erikson's trust vs. mistrust crisis, which occurs during infancy (birth to 1 year). This first stage of psychosocial development centers on whether infants can trust their caregivers to reliably meet their basic needs for food, comfort, and affection. The consistently responsive caregiver helped the infant develop basic trust, which forms the foundation for all future relationships and social development. When caregivers are reliable and responsive, infants develop a sense that the world is safe and dependable, leading them to expect others to be trustworthy as well. This basic trust becomes an enduring aspect of personality that influences how individuals approach relationships throughout life. Failure to develop trust during this stage leads to mistrust, suspicion, and fear of others. This differs from later stages like autonomy vs. shame and doubt (toddler independence), initiative vs. guilt (preschool planning), and industry vs. inferiority (school-age competence). The caregiver's consistency and the infant's later expectation of dependability indicate successful trust development.
