Affect Measures
Affect measures (measures of affect or measures of emotion) are used in the study of human affect (including emotions and mood), and refer to measures obtained from self-report studies asking participants to quantify their current feelings or average feelings over a longer period of time. Even though some affect measures contain variations that allow assessment of basic predispositions to experience a certain emotion, tests for such stable traits are usually considered to be personality tests. Differentiating affect from other terms Scholarly work has noted the problematic nature of using the terms “emotion”, “affect” and “mood” interchangeably. A lack of thorough understanding of these concepts could influence the choice of measures used in assessing the emotional components of interest in a study, leading to a less optimal research result. The differentiation among these key concepts in affect research in the current era is becoming increasingly important, as consi ...

Affect (psychology)
Affect, in psychology, refers to the underlying experience of feeling, emotion or mood. History The modern conception of affect developed in the 19th century with Wilhelm Wundt. The word comes from the German ''Gefühl'', meaning "feeling." A number of experiments have been conducted in the study of social and psychological affective preferences (i.e., what people like or dislike). Specific research has been done on preferences, attitudes, impression formation, and decision-making. This research contrasts findings with recognition memory (old-new judgments), allowing researchers to demonstrate reliable distinctions between the two. Affect-based judgments and cognitive processes have been examined with noted differences indicated, and some argue affect and cognition are under the control of separate and partially independent systems that can influence each other in a variety of ways (Zajonc, 1980). Both affect and cognition may constitute independent sources of effects within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Likert Scale
A Likert scale ( , commonly mispronounced as ) is a psychometric scale commonly involved in research that employs questionnaires. It is the most widely used approach to scaling responses in survey research, such that the term (or more fully the Likert-type scale) is often used interchangeably with ''rating scale'', although there are other types of rating scales. The scale is named after its inventor, psychologist Rensis Likert. Likert distinguished between a scale proper, which emerges from collective responses to a set of items (usually eight or more), and the format in which responses are scored along a range. Technically speaking, a Likert scale refers only to the former. The difference between these two concepts has to do with the distinction Likert made between the underlying phenomenon being investigated and the means of capturing variation that points to the underlying phenomenon. When responding to a Likert item, respondents specify their level of agreement or disagree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-report Inventory
A self-report inventory is a type of psychological test in which a person fills out a survey or questionnaire with or without the help of an investigator. Self-report inventories often ask direct questions about personal interests, values, symptoms, behaviors, and traits or personality types. Inventories are different from tests in that there is no objectively correct answer; responses are based on opinions and subjective perceptions. Most self-report inventories are brief and can be taken or administered within five to 15 minutes, although some, such as the Minnesota Multiphasic Personality Inventory (MMPI), can take several hours to fully complete. They are popular because they can be inexpensive to give and to score, and their scores can often show good reliability. There are three major approaches to developing self-report inventories: theory-guided, factor analysis, and criterion-keyed. Theory-guided inventories are constructed around a theory of personality or a prototype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positive Affectivity
Positive affectivity (PA) is a human characteristic that describes how much people experience positive affects (sensations, emotions, sentiments); and as a consequence how they interact with others and with their surroundings. People with high positive affectivity are typically enthusiastic, energetic, confident, active, and alert. Research has linked positive affectivity with an increase in longevity, better sleep, and a decrease in stress hormones. People with a high positive affectivity have healthier coping styles, more positive self-qualities, and are more goal oriented. Positive affectivity also promotes an open-minded attitude, sociability, and helpfulness. Those having low levels of positive affectivity (and high levels of ''negative'' affectivity) are characterized by sadness, lethargy, distress, and un-pleasurable engagement (see negative affectivity). Low levels of positive affect are correlated with social anxiety and depression, due to decreased levels of dopamine. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negative Affectivity
Negative affectivity (NA), or negative affect, is a personality variable that involves the experience of negative emotions and poor self-concept. Negative affectivity subsumes a variety of negative emotions, including anger, contempt, disgust, guilt, fear, and nervousness. Low negative affectivity is characterized by frequent states of calmness and serenity, along with states of confidence, activeness, and great enthusiasm. Individuals differ in negative emotional reactivity.Tellegen, A. (1985). Structures of mood and personality and their relevance to assessing anxiety, with an emphasis on self-report. In A. H. Tuma & J. D. Maser (Eds.), Anxiety and the Anxiety disorders, (pp. 681-706), Hilssdale, NJ: Erlbaum. Trait negative affectivity roughly corresponds to the dominant personality factor of anxiety/neuroticism that is found within the Big Five personality traits as emotional stability. The Big Five are characterized as openness, conscientiousness, extraversion, agreeableness, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotion Classification
Emotion classification, the means by which one may distinguish or contrast one emotion from another, is a contested issue in emotion research and in affective science. Researchers have approached the classification of emotions from one of two fundamental viewpoints: # that emotions are discrete and fundamentally different constructs # that emotions can be characterized on a dimensional basis in groupings Emotions as discrete categories In discrete emotion theory, all humans are thought to have an innate set of basic emotions that are cross-culturally recognizable. These basic emotions are described as "discrete" because they are believed to be distinguishable by an individual's facial expression and biological processes. Theorists have conducted studies to determine which emotions are basic. A popular example is Paul Ekman and his colleagues' cross-cultural study of 1992, in which they concluded that the six basic emotions are anger, disgust, fear, happiness, sadness, and su ...

Anger
Anger, also known as wrath or rage, is an intense emotional state involving a strong uncomfortable and non-cooperative response to a perceived provocation, hurt or threat. A person experiencing anger will often experience physical effects, such as increased heart rate, elevated blood pressure, and increased levels of adrenaline and noradrenaline. Some view anger as an emotion which triggers part of the fight or flight response. Anger becomes the predominant feeling behaviorally, cognitively, and physiologically when a person makes the conscious choice to take action to immediately stop the threatening behavior of another outside force. The English word originally comes from the term ''anger'' from the Old Norse language. Anger can have many physical and mental consequences. The external expression of anger can be found in facial expressions, body language, physiological responses, and at times public acts of aggression. Facial expressions can range from inward angling of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psychometrics
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally refers to specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, mental disorders, and educational achievement. The levels of individuals on nonobservable latent variables are inferred through mathematical modeling based on what is observed from individuals' responses to items on tests and scales. Practitioners are described as psychometricians, although not all who engage in psychometric research go by this title. Psychometricians usually possess specific qualifications such as degrees or certifications, and most are psychologists with advanced graduate training in psychometrics and measurement theory. I ...

Cronbach's Alpha
Cronbach's alpha (Cronbach's \alpha), also known as tau-equivalent reliability (\rho_T) or coefficient alpha (coefficient \alpha), is a reliability coefficient that provides a method of measuring internal consistency of tests and measures. Numerous studies warn against using it unconditionally, and note that reliability coefficients based on structural equation modeling (SEM) are in many cases a suitable alternative.Sijtsma, K. (2009). On the use, the misuse, and the very limited usefulness of Cronbach's alpha. Psychometrika, 74(1), 107–120. Green, S. B., & Yang, Y. (2009). Commentary on coefficient alpha: A cautionary tale.

Construct Validity
Construct validity concerns how well a set of indicators represent or reflect a concept that is not directly measurable. ''Construct validation'' is the accumulation of evidence to support the interpretation of what a measure reflects.Polit DF Beck CT (2012). Nursing Research: Generating and Assessing Evidence for Nursing Practice, 9th ed. Philadelphia, USA: Wolters Klower Health, Lippincott Williams & Wilkins Modern validity theory defines construct validity as the overarching concern of validity research, subsuming all other types of validity evidence such as content validity and criterion validity. Construct validity is the appropriateness of inferences made on the basis of observations or measurements (often test scores), specifically whether a test can reasonably be considered to reflect the intended construct. Constructs are abstractions that are deliberately created by researchers in order to conceptualize the latent variable, which is correlated with scores on a given measure ...

Conceptual Act Model Of Emotion
The theory of constructed emotion (formerly the conceptual act model of emotion) is a theory in affective science proposed by Lisa Feldman Barrett to explain the experience and perception of emotion. The theory posits that instances of emotion are constructed predictively by the brain in the moment as needed. It draws from social construction, psychological construction, and neuroconstruction. Motivation Barrett proposed the theory to resolve what she calls the "emotion paradox," which she claims has perplexed emotion researchers for decades, and describes as follows: People have vivid and intense experiences of emotion in day-to-day life: they report seeing emotions like "anger", "sadness", and "happiness" in others, and they report experiencing "anger", "sadness" and so on themselves. Nevertheless, psychophysiological and neuroscientific evidence has failed to yield consistent support for the existence of such discrete categories of experience. Instead, the empirical evidence ...
