Meeting Life Challenges

To solve the problem of matching List-I with List-II, let's first understand each term:

(A) Task-Oriented Strategy typically involves practical approaches to tackle tasks and is often linked to dynamic situation specific reaction to stress.
(B) Emotion-Oriented Strategy involves managing emotions, such as talking to friends or watching T.V., to handle stress.
(C) Avoidance-Oriented Strategy involves avoiding stress-inducing situations or thinking, characterized by worrying about what to do rather than taking immediate action.
(D) Coping refers to maintaining a time schedule or developing structured ways to handle stress.
Based on these descriptions, the correct matching is:

• (A) Task-Oriented Strategy - (I) Dynamic situation specific reaction to stress
• (B) Emotion-Oriented Strategy - (IV) Talking to friends or watching T.V.
• (C) Avoidance-Oriented Strategy - (III) Worry about what I am going to do
• (D) Coping - (II) Maintaining a time schedule

Thus, the correct answer is (A) - (I), (B) - (IV), (C) - (III), (D) - (II).

Psychoneuroimmunology explores the interplay between psychological processes, the nervous system, and the immune response. Let's examine the given statements:

• (A) The leucocytes within the immune system identify and destroy antigens such as viruses. True. Leucocytes, or white blood cells, are crucial for identifying and eradicating pathogens like viruses.
• (B) Stress does not affect natural killer cell cytotoxicity. False. Stress is known to suppress immune functions, including the activity of natural killer (NK) cells, reducing their ability to destroy malignancies and infected cells.
• (C) Stress leads to the production of antibodies. True. Stress can stimulate the production of certain antibodies through the activation of the body's stress response systems.
• (D) There are several kinds of leucocytes, including the T cells, B cells, and natural killer cells. True. The immune system comprises various leucocytes such as T cells, B cells, and NK cells, which perform diverse roles in immune defense.
• (E) D-cells produce antibodies. False. D-cells are not involved in antibody production; B cells produce antibodies as part of the adaptive immune response.

Given this analysis, the correct statements are (A), (C), and (D). The correct answer is therefore: (A), (C) & (D) only.

The General Adaptation Syndrome (GAS) is a concept in psychology that explains the body's short-term and long-term reactions to stress. It is typically divided into three main stages:

1. Alarm Reaction: This is the initial stage where the body recognizes the presence of a noxious stimulus and begins a fight-or-flight response to meet the challenge. This stage corresponds to the presence of a stressor, and the body reacts immediately.
2. Resistance: If the stressor persists, the body enters the resistance stage. During this period, the body attempts to adapt to the stressor. Physiological responses are stabilized in an attempt to maintain homeostasis while still remaining alert and prepared for potential threats.
3. Exhaustion: Prolonged exposure to the stressor eventually leads to the exhaustion stage. At this point, the body's resources are depleted, and its ability to resist is compromised, potentially leading to illness or other health issues.

Given these stages, the correct sequence based on the provided options follows as:

• (B) Presence of a noxious stimulus
• (C) Alarm Reaction
• (A) Resistance
• (D) Exhaustion

The correct order of the General Adaptation Syndrome is therefore: (B), (C), (A), (D).

David's feelings of energy, heightened awareness, and excitement before a marathon are best categorized as eustress. In psychology, stress is commonly distinguished into two types: distress and eustress.

• Distress: This refers to negative stress, which can lead to anxiety, poor performance, and other harmful effects.
• Eustress: This is a positive form of stress that can enhance performance and well-being. It is often associated with feelings of excitement, motivation, and anticipation that improve focus and productivity. David's experience aligns with this definition, as his feelings are a precursor to anticipated good performance.
• Strain: Typically refers to the effort or tension resulting from stress, which is not directly linked to positive outcomes like eustress.
• Frustration: A feeling of being upset or annoyed, usually because of an inability to achieve something, which doesn't correlate with the positive anticipatory feelings David experiences.

Thus, David's emotional state before the marathon is an example of eustress, highlighting his readiness and enthusiasm for the upcoming challenge.

In the field of psychology, understanding how external factors such as noise impact task performance is crucial. Several characteristics influence this effect:

• Intensity: Refers to how loud the noise is. High intensity can significantly disrupt task performance by hindering concentration.
• Predictability: Involves whether the noise occurs at expected times. Unpredictable noise tends to be more disruptive because it can catch the individual off guard.
• Controllability: Concerns whether the individual can control or stop the noise. When individuals have control over noise, its negative impact on performance is usually reduced.

However, Luminance, which relates to light intensity and brightness, does not determine the effect of noise on task performance. Therefore, it is the characteristic that does not contribute to how noise affects task performance.

Holmes and Rahe stress scale is a list of 43 stressful life events that can contribute to illness. Each event is assigned a score representing its severity. For this question, we need to arrange the events in sequence from highest to lowest severity based on the scale.

1. Death of a close family member (D): This event ranks among the highest on the Holmes and Rahe scale due to its profound emotional impact and long-term effects on life stability.
2. Unexpected accident or trauma (A): Such events also carry high scores due to their sudden nature and potential for causing significant disruption in a person's life.
3. Illness of a family member (C): The stress caused by dealing with an illness in the family can be significant, though generally less severe than death or personal trauma.
4. Break-up with a friend (B): While personal relationships are very important, the stress score is lower compared to severe family-related events.
5. Change in eating habits (E): This is considered a lower-stress event, as changes in lifestyle habits are often manageable with minimal long-term effects.

Thus, the correct sequence from highest to lowest severity is: (D), (A), (C), (B), (E).
