Dispositional affect

Dispositional affect, similar to mood, is a personality trait or overall tendency to respond to situations in stable, predictable ways. This trait is expressed by the tendency to see things in positive or negative way. People with high positive affectivity tend to perceive things through “pink lens” while people with high negative affectivity tend to perceive things through “black lens”. The level of dispositional affect effects the sensations and behavior immediately and most of the time in unconscious way, and its effect can be prolonged (between a few weeks to a few months). Many researches show that there is a correlation between dispositional affect (both positive and negative) and important aspects in psychology and social science, such as personality, culture, decision making, negotiation, psychological resilience and coping with stressful life events. That is why this topic is important both in social psychology research and organizational psychology research.

Conceptual distinctions from emotion and mood
Besides dispositional affect, there are other concepts for expressions of emotion such as mood or discrete emotions. These concepts are different from dispositional affect though there is a connection among them.
 * Dispositional affect is different from emotion or affect, by being a personality trait while emotion is a general concept for subjective responses of people to certain situations. Emotion includes both general responses (positive or negative emotion) and specific responses (love, anger, hate, fear, jealousy, sadness etc. The strength of emotions a person feels can stem from his level of dispositional affect.
 * Dispositional affect is also different from moods since mood relates to general feeling that usually tends to be diffusing and not focused on a specific cause or object. Though mood is specific, it is not a personality trait. Still, positive affectivity can explain why a person has good mood in general, since positive affectivity means viewing the world in a good light. The same thing is true for negative affectivity which can explain why a person has bad mood in general, since negative affectivity means viewing the world in a dark light.

Dimensions
In general, though emotion researchers disagree about the way that emotions and dispositional affect should be classified, a common classification of emotions assumes that each emotion is a combination of pleasantness (pleasant or unpleasant) and activation (high or low)) . For example, excitement is a combination of pleasantness and high activation, while calmness is a combination of pleasantness and low activation. Dispositional Affect is also a combination of pleasantness and activation. According to this classification, the different combinations of high or low pleasantness and high or low activation create four Quarters. In line with the classification mentioned above, there is a well-known and common model that is being used in organizational psychology research to analyze and classify dispositional affect, which was developed by Watson and Tellegen . The researchers claim that there are two dimensions of dispositional affect: positive affectivity and negative affectivity and that each person has a certain level of both positive affectivity and negative affectivity. Hence, according to the model and contrary to intuition, positive affectivity does not represent the opposite of negative affectivity, but a different aspect from it. According to Watson & Tellegen one must regard these quarters as two pivots which determine the positive affectivity and negative affectivity of a person. These two dimensions of dispositional affect are bipolar, distinct and independent, relating to different emotion groups, so that each person can be classified with a positive affectivity and negative affectivity grade.
 * Positive affectivity - describes a person's tendency to be cheerful and energetic, and who experience positive moods, (such as pleasure or well-being), across a variety of situations. Individuals who have low levels of positive affectivity tend to be low energy and sluggish or melancholy. High level of positive affectivity represents the extent to which an individual feels energetic and excited, while low level of positive affectivity represents the extent to which an individual feels sadness, sluggishness or weariness ".
 * Negative affectivity - describes a person's tendency to be distressed and upset, and have a negative view of self over time and across situations. It is important to explain that low levels of negative affectivity are perceived as positive traits since they represent individuals who are more calm, serene and relaxed. High levels of negative affectivity represents the extent to which an individual feels anger, irritability, fear or nervousness, while low level of negative affectivity represents the extent to which an individual feels calm and serene ".

Measurement
Operationalizations for dispositional affect can be measured by questionnaires. In English researchers Use the Positive And Negative Affectivity Scale (PANAS). According to the instructions of this questionnaire, the individual is asked to indicate to what extent he or she feels a certain feeling or emotion such as happy, sad, excited, enthusiastic, guilty, distressed, afraid, etc. An individual has to indicate the most appropriate answer to each item (feeling or emotion) on a scale ranging from 1-5 (1- Very slightly or not at all, 5- Extremely). Early mapping of these emotions by the researchers, helps determine the positive affectivity and negative affectivity of the individual. Another advantage that was discovered while developing this questionnaire is that though it is intended for personality analysis, people can respond to the questions according to specific time frames, for example people can indicate the emotions or sensations they feel at this moment, in the past week, or in general. This way we can learn about dispositional affect to a certain situation and not only about dispositional affect as a general personality trait. By responding to the questions about feelings "in general" we can learn about positive and negative affectivity as a personality trait. By responding to the questions about feelings "at this moment" we can learn about situational dispositional affect as a response to a certain situation. For example, Rafaeli et al., showed in their research that waiting in line cause an increase in negative affectivity levels.

Physical and mental aspects

 * Physical health - When it comes to people with different illness, it is interesting to see that there are differences in the physical health according to the levels of dispositional affect. Individuals who have high levels of positive affectivity, had longer life span, reported fewer pains and illness symptoms (such as blood pressure), and were less likely to develop a cold when exposed to a virus compared with individuals who have high levels of negative affectivity, while both had the same illness. It was also discovered that when it comes to people with chronic diseases that has decent prospects for long-term survival, (such as coronary heart disease), people may benefit from high levels of positive affectivity. However, when it comes to people with chronic diseases that has short - term Prognoses (e.g., metastatic breast cancer) and poor survival chances, high levels of positive affectivity may be detrimental to the health of these individuals, possibly as a consequence of underreporting of symptoms resulting in inadequate care, or of a lack of adherence to treatment.
 * Life style - Even when it comes to healthy individuals, it seems that there are differences between people's life style, due to their dispositional affect trait .Individuals who have high levels of positive affectivity, tend to attend healthier activities such as improved sleep quality, more physical exercise, and more intake of dietary vitamins, and tend to socialize more often and maintain more and higher-quality social ties. It was also found that high levels of positive affectivity may result in more and closer social contacts because it facilitates approach behavior, and because others are drawn to form attachments with pleasant individuals.
 * Psychological resilience and coping with stressful life events - Research findings show that there is a relationship between positive affectivity and improved physical health and healthier life style, but what is the explanation to the correlation between dispositional affect and psychological resilience and coping with stressful life events? Physiology gives one explanation, which claims that individuals who have high levels of positive affectivity, have lower levels of the stress hormones (such as epinephrine, norepinephrine, and cortisol), so that it creates a psychological resilience that provides positive resources to confront stressful life events . On the other hand, the broaden-and-build theory provides a different explanation from the physiological one, and claim that individuals who have high levels of positive affectivity and experience positive events in the present, create a spiral or “snow ball” effect, that may lead to higher probability to experience positive events in the future as well. This means that happiness and well-being sensations in the present, are the ones which creates the likelihood to feel the same in the future, which helps us in building a strong and improved system of coping with stressful life events.

Culture
Though it is agreed that there are differences between one culture and another, most of the differences that were addressed in researches are related to the comparison between individualism and collectivism. In individualistic cultures, it was found that there is a strong relationship between dispositional affect (either positive or negative) and general life satisfaction (though the relationship was stronger for positive affectivity compared to negative affectivity). On the other hand, in many collectivistic cultures, it was found that there is a no relationship between negative affectivity and general life satisfaction, and it may result from the great variance in the ways that different cultures regulate their positive affectivity compared to negative affectivity.

Decision making and negotiation

 * Decision making - In dealing with interesting and important situations, it was found that individuals who have high levels of positive affectivity make a thorough and efficient cognitive processing, and therefore their decision making process is more efficient, flexible, creative and innovative. It was also found that positive affectivity facilitate creativity, cognitive flexibility, novel responses, openness to new information and dealing with mental problems. This stems from the fact that positive affectivity encourages problem solving approach and searching for variety, in order to achieve a suitable result. At last, it was found that high levels of positive affectivity does not encourage risk taking, though it does facilitates negotiation processes, and improves the results of face to face negotiation processes, in order to reach to agreement.
 * Negotiation - When individuals negotiate, it was found that high levels of positive affectivity was related to optimistic view of the upcoming results, planning and using cooperation strategies, and better results regarding the agreements that were made, both in personal (and not formal) negotiation, and group (formal) negotiation. It was also found that positive affectivity increases the likelihood to use cooperation strategies (but not other strategies such as “an eye for an eye”) and improves the results of the negotiation, even if just one of the negotiators has the desired trait of positive affectivity, and increases the likelihood and willingness to agree with counter–arguments, and behavior changes as a result . Another support for the findings presented above, showed that high levels of positive affectivity was related to willingness to compromise and give up, finding creative solutions, using cooperative strategies, less cheating and better results in negotiation processes . On the contrary to the findings about positive affectivity, it was found that high levels of negative affectivity was related to usage of competitive strategies, and much worse results regarding the agreements that were made. Another support for these finding showed that high levels of negative affectivity was related to competition, lower offers, rejecting ultimatums and lower combined gains, as a result of the negotiation process, and minimum willingness to continue the cooperation strategy in the future.
