IntrospectionIntrospection is the examination of one's own conscious thoughts and feelings. In psychology, the process of introspection relies on the observation of one's mental state, while in a spiritual context it may refer to the examination of one's soul. Introspection is closely related to human self-reflection and self-discovery and is contrasted with external observation. It generally provides a privileged access to one's own mental states, not mediated by other sources of knowledge, so that individual experience of the mind is unique.
Reflection (physics)Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection (for example at a mirror) the angle at which the wave is incident on the surface equals the angle at which it is reflected. In acoustics, reflection causes echoes and is used in sonar. In geology, it is important in the study of seismic waves.
Specular reflectionSpecular reflection, or regular reflection, is the mirror-like reflection of waves, such as light, from a surface. The law of reflection states that a reflected ray of light emerges from the reflecting surface at the same angle to the surface normal as the incident ray, but on the opposing side of the surface normal in the plane formed by the incident and reflected rays. This behavior was first described by Hero of Alexandria (AD c. 10–70). Later, Alhazen gave a complete statement of the law of reflection.
Introspection illusionThe introspection illusion is a cognitive bias in which people wrongly think they have direct insight into the origins of their mental states, while treating others' introspections as unreliable. The illusion has been examined in psychological experiments, and suggested as a basis for biases in how people compare themselves to others. These experiments have been interpreted as suggesting that, rather than offering direct access to the processes underlying mental states, introspection is a process of construction and inference, much as people indirectly infer others' mental states from their behaviour.
Video game controversiesVideo game controversies refers to a wide range of debates on the social effects of video games on players and broader society, as well as debates within the video game industry. Since the early 2000s, advocates of video games have emphasized their use as an expressive medium, arguing for their protection under the laws governing freedom of speech and also as an educational tool. Detractors argue that video games are harmful and therefore should be subject to legislative oversight and restrictions.
Video game industryThe video game industry is the tertiary and quaternary sectors of the entertainment industry that specialize in the development, marketing, distribution, monetization and consumer feedback of video games. The industry encompasses dozens of job disciplines and thousands of jobs worldwide. The video game industry has grown from niche to mainstream. , video games generated annually in global sales. In the US, the industry earned about in 2007, in 2008, and 2010, according to the ESA annual report.
Video game developmentVideo game development (or gamedev) is the process of developing a video game. The effort is undertaken by a developer, ranging from a single person to an international team dispersed across the globe. Development of traditional commercial PC and console games is normally funded by a publisher and can take several years to reach completion. Indie games usually take less time and money and can be produced by individuals and smaller developers.
Structuralism (psychology)Structuralism in psychology (also structural psychology) is a theory of consciousness developed by Wilhelm Wundt and his student Edward Bradford Titchener. This theory was challenged in the 20th century. Structuralism as a school of psychology seeks to analyze the adult mind (the total sum of experience from birth to the present) in terms of the simplest definable components and then to find how these components fit together to form more complex experiences as well as how they correlate to physical events.
Diffuse reflectionDiffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection. An ideal diffuse reflecting surface is said to exhibit Lambertian reflection, meaning that there is equal luminance when viewed from all directions lying in the half-space adjacent to the surface.
Reflection (mathematics)In mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points; this set is called the axis (in dimension 2) or plane (in dimension 3) of reflection. The image of a figure by a reflection is its in the axis or plane of reflection. For example the mirror image of the small Latin letter p for a reflection with respect to a vertical axis (a vertical reflection) would look like q.
Glide reflectionIn 2-dimensional geometry, a glide reflection (or transflection) is a symmetry operation that consists of a reflection over a line and then translation along that line, combined into a single operation. The intermediate step between reflection and translation can look different from the starting configuration, so objects with glide symmetry are in general, not symmetrical under reflection alone. In group theory, the glide plane is classified as a type of opposite isometry of the Euclidean plane.
Gilbert RenaultGilbert Renault (August 6, 1904 – July 29, 1984), known by the nom de guerre Colonel Rémy, was a notable French secret agent active in World War II, and was known under various pseudonyms such as Raymond, Jean-Luc, Morin, Watteau, Roulier, Beauce and Rémy. Gilbert Renault was born in Vannes, France, the oldest child of a Catholic family of nine children. His father was a professor of Philosophy and English, and later the inspector general of an insurance company.
