Excitation-transfer Theory
Excitation-transfer theory purports that residual excitation from one stimulus will amplify the excitatory response to another stimulus, though the hedonic valences of the stimuli may differ. The excitation-transfer process is not limited to a single emotion. For example, when watching a movie, a viewer may be angered by seeing the hero wronged by the villain, but this initial excitation may intensify the viewer's pleasure in witnessing the villain's punishment later. Thus, although the excitation from the original stimulus of seeing the hero wronged was cognitively accessed as anger, the excitation after the second stimulus of seeing the villain punished is cognitively assessed as pleasure, though part of the excitation from the second stimulus is residual from the first. However, the excitation-transfer process requires the presence of three conditions. One: the second stimulus occurs before the complete decay of residual excitation from the first stimulus. Two: there is the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stimulus (physiology)
In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity (excitability). Sensory receptors can receive information from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a homeostatic control system. External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response. In order for a stimulus to be detected with high probability, its level of strength must exceed the absolute threshold; if a signal does reach threshold, the information is transmitted to ...

Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Mediated Messages
''Mediated: How the Media Shapes Your World and the Way You Live in It'' is a non-fiction book by anthropologist Thomas de Zengotita published in 2005 by Bloomsbury about the effect of the media in the Western world. Summary ''Mediated'' aims at creating awareness rather than offering ready-made solutions to remedy the intrusion of too much media in our industrial societies. Rather than writing yet another pamphlet against the media, the author chooses to focus on the mechanisms and the processes of our ''mediated'' society. The basis of his analysis is that the opposite of reality is not phony or superficial, it is optional. We choose between options to determine who we are, to make statements to the world about who we are. People, he argues, have always done so, but the difference with today's situation is that we have a lot more options. In terms of options, comparing the modern world with the post-modern world is like comparing a breeze with a hurricane. The media force ...

Communication Stimuli
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a universal phenomenon and a specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions. An important distinction is between verbal communication, which happens through the use of a language, and no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Media
Mass media refers to a diverse array of media technologies that reach a large audience via mass communication. The technologies through which this communication takes place include a variety of outlets. Broadcast media transmit information electronically via media such as films, radio, recorded music, or television. Digital media comprises both Internet and mobile mass communication. Internet media comprise such services as email, social media sites, websites, and Internet-based radio and television. Many other mass media outlets have an additional presence on the web, by such means as linking to or running TV ads online, or distributing QR codes in outdoor or print media to direct mobile users to a website. In this way, they can use the easy accessibility and outreach capabilities the Internet affords, as thereby easily broadcast information throughout many different regions of the world simultaneously and cost-efficiently. Outdoor media transmit information via such media ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Experiment
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into Causality, cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experiment, natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Media Violence Research
The studies of violence in mass media analyzes the degree of correlation between themes of violence in media sources (particularly violence in video games, television and films) with real-world aggression and violence over time. Many social scientists support the correlation. However, some scholars argue that media research has methodological problems and that findings are exaggerated. Other scholars have suggested that the correlation exists, but can be unconventional to what is mainly believed. Complaints about the possible deleterious effects of mass media appear throughout history; Plato was concerned about the effects of plays on youth. Various media/genres, including dime novels, comic books, jazz, rock and roll, role playing/computer games, television, films, internet (by computer or cell phone) and many others have attracted speculation that consumers of such media may become more aggressive, rebellious or immoral. This has led some scholars to conclude statements made by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Media Influence
In media studies, mass communication, media psychology, communication theory, and sociology, media influence and the media effect are topics relating to mass media and media culture's effects on individual or an audience's thoughts, attitudes, and behavior. Whether it is written, televised, or spoken, mass media reaches a large audience. Mass media's role and effect in shaping modern culture are central issues for study of culture. At present, mass media is the mainstream trend of media development, information dissemination presents the characteristics of diversification and interaction, and its influence on social life is also constantly expanding. The influence of ''mass media'' or 'The media effect' affects many aspects of human life, which can include voting a certain way, individual views and beliefs, or skewing a person's knowledge of a specific topic due to being provided false information. The overall influence of mass media has increased drastically over the years, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biochemistry
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells,Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs, as well as organism structure and function.Miller (2012). p. 62. Biochemistry is closely related to molecular biology, which is the study of the molecular mechanisms of biological phenomena.As ...

Psychophysiology
Psychophysiology (from Ancient Greek, Greek , ''psȳkhē'', "breath, life, soul"; , ''physis'', "nature, origin"; and , ''wiktionary:-logia, -logia'') is the branch of psychology that is concerned with the physiology, physiological bases of psychology, psychological processes. While psychophysiology was a general broad field of research in the 1960s and 1970s, it has now become quite specialized, based on methods, topic of studies and scientific traditions. Methods vary as combinations of electrophysiological methods (such as EEG), neuroimaging (MRI, Positron emission tomography, PET), and neurochemistry. Topics have branched into subspecializations such as social, sport, cognitive, cardiovascular, clinical and other branches of psychophysiology. Background Some people have difficulty distinguishing a psychophysiologist from a Physiological psychology, physiological psychologist, two very different perspectives.

Arousal
Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception. It involves activation of the ascending reticular activating system (ARAS) in the brain, which mediates wakefulness, the autonomic nervous system, and the endocrine system, leading to increased heart rate and blood pressure and a condition of sensory alertness, desire, mobility, and readiness to respond. Arousal is mediated by several neural systems. Wakefulness is regulated by the ARAS, which is composed of projections from five major neurotransmitter systems that originate in the brainstem and form connections extending throughout the cortex; activity within the ARAS is regulated by neurons that release the neurotransmitters acetylcholine, norepinephrine, dopamine, histamine, and serotonin. Activation of these neurons produces an increase in cortical activity and subsequently alertness. Arousal is important in regulating consciousness, attention, alertn ...
