Q

Describe James-Lange Theory

A

This theory states that emotion is a result of physiological reactions to different events around us; stimulus results in physiological arousal which leads to a secondary response in which emotion is labeled
“I feel afraid because I tremble”

Q

Describe Schachter-Singer Theory

A

This states that both arousal and the labeling of arousal based on environment must occur in order for an emotion to be experienced;
“I label my trembling as fear because I appraise the situation as dangerous”

Q

What is the function of the Amygdala?

A

Signals the cortex about stimuli related to attention and emotions, processes the environment by detecting external cues and learns from the persons surroundings in order to produce emotion, prepares for a fight-or-flight response

Q

What is the function of the Hippocampus?

A

Primarily involved in creating long term memories;
In conjunction with the amygdala and hypothalamus it is involved in the storage and retrieval of emotional memories and producing emotional response;
Aids in creating context for stimuli to lead to an emotional experience;

A

Emotional Experience

29
Q

Function of Ventromedial Prefrontal Cortex

A

Decision-making & Emotional Responses

30
Q

Characteristics of the ANS

A

Part of the PNS, divided into two systems, located in the medulla oblongata and regulated by the hypothalamus

31
Q

What is the function of the ANS

A

Physiological reactions associated with specific emotions; skin temperatures, HR, BR and BP

32
Q

Parasympathetic Nervous System

A

Rest & Digest Response

  • Increase stomach activity
  • Pupillary constriction
  • Decreased blood flow to muscles
  • Decreased HR and Respiration rate
33
Q

Sympathetic Nervous System

A

Fight or Flight Response

  • Releases epinephrine from adrenal glands
  • Increases HR and Respiration rate
  • Increases Blood Glucose & BP
  • Pupillary dilation
  • Slows digestive activity
34
Q

What is the galvanic skin response?

A

It measures emotion, the autonomic response includes BP, HR, RR and Muscle Tension

35
Q

What is Appraisal?

A

It is the subjective evaluation of a situation that induces stress

36
Q

What are the stages of appraisal?

A

Primary & Secondary Appraisal

37
Q

Primary Appraisal is

A

the initial examination which results in identification of stress as irrelevant, benign-positive or stressful

38
Q

Secondary Appraisal is

A

an evaluation of one’s ability to cope with stress; it involves evaluation of harm, threat and the challenge

39
Q

What are the categories of stressors?

A

A

Pressure, Control, Predictability, Frustration & Conflict

43
Q

What does control produce?

A

Reduced stress levels if one is in control of their surroundings and increased stress levels if one cannot control their stress levels

44
Q

What does predictability produce?

A

It reduces stress levels if the daily scenario can be predicted

45
Q

What does frustration produce?

A

It increases stress levels when attaining a goal or need is prevented

A

Stressors that arise from the need to make a choice

47
Q

What are the three kinds of conflict stressors?

A

Approach-Approach
Avoidance-Avoidance
Approach-Avoidance

48
Q

Describe Approach-Approach conflicts

A

These result from the need to choose between two desirable options

49
Q

Describe Avoidance-Avoidance conflicts

A

These result from the need to choose between two negative options

50
Q

Describe Approach-Avoidance

A

These result when only one choice that has either positive or negative outcomes

51
Q

How does stress effect psychological functions?

A

It causes depression, anxiety or PTSD

52
Q

What are the physiological responses to stressors?

A

The body reacts via sympathetic nervous systems initiating increase in HR and decrease in digestion; all available energy being reserved for reacting to the stressful event

53
Q

What are the sequences of responses in General Adaptation Syndrome?

A

Alarm
Resistance
Exhaustion

54
Q

Describe the Alarm reaction

A

The body prepares itself to deal with stressors;

Hypothalamus stimulates the pituitary to secrete ACTH which stimulates production of cortisol;

Activates secretion of epinephrine and norepinephrine

55
Q

What is the function of cortisol?

A

Maintain the steady supply of blood sugar needed to respond to stressful events

56
Q

Describe the Resistance reaction

A

The continuous release of hormones allows the sympathetic nervous system to remain engaged to fight the stressor;

57
Q

Describe the Exhaustion reaction

A

When the body can no longer maintain an elevated response with sympathetic nervous system activity; there is an increased susceptibility to illnesses and medical conditions, anxiety, depression and poor judgments

58
Q

Emotional Responses to Stress

A

They influence our mood and sense of well-being

Elevated stress levels can result in people feeling irritable, moody, tense, fearful and helpless & difficulty with concentration and memory

59
Q

Behavioral Responses to Stress

A

Changes in daily activity, poor judgment, changing eating habits and irritability; these can include personal withdrawal, difficulties at work or school, substance use, aggression and suicide

60
Q

What are the two types of coping strategies?

A

They are either problem focused or emotionally focused

61
Q

What are problem focused strategies?

A

Working to overcome a stressor such as reaching out to family and friends for social support, confronting the issue head-on and creating/following a plan of problem-solving actions

62
Q

What are emotionally focused strategies?

A

Strategies center on changing one’s feelings about a stress - engaging in self control, distancing oneself from the issue, engaging in wishful thikning

63
Q

What does stress management do?
