Functional Cerebral Distance
Functional Cerebral Distance is a neuropsychological principle developed by Marcel Kinsbourne. It states that, "...separate control centers that are functionally close together (i.e., highly connected in functional cerebral space) will conflict if they are independently engaged in unrelated activity." In other words, when a person attempts to perform multiple tasks associated with functionally close brain structures, interference occurs and performance is affected. The concept of functional cerebral distance is the basis for some research into hostility. According to the Direction Model, anger activates the left prefrontal cortex. Counting also activates similar functional cerebral space, creating competition between the two activities according to Kinsbourne. This is the basis behind "counting to 10" when one is feeling angry or frustrated. Kinsbourne's work is also the basis for Capacity Theory, which postulates that diminished right frontal lobe capacity is the cause for overly ...

Neuropsychology
Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology focus on how injuries or illnesses of the brain affect cognitive and behavioral functions. It is both an experimental and clinical field of patient-focused psychology. Thus aiming to understand how behavior and cognition are influenced by brain function. It is also concerned with the diagnosis and treatment of behavioral and cognitive effects of neurological disorders. Whereas classical neurology focuses on the pathology of the nervous system and classical psychology is largely divorced from it, neuropsychology seeks to discover how the brain correlates with the mind through the study of neurological patients. It thus shares concepts and concerns with neuropsychiatry and with behavioral neurology in general. The term ''neuropsychology'' has been applied to lesion studies in huma ...

Marcel Kinsbourne
Marcel Kinsbourne (3 November 1931 – 21 April 2024) was an Austrian-born pediatric neurologist and cognitive neuroscientist who was an early pioneer in the study of brain lateralization. Background Kinsbourne was born in Vienna, Austria on 3 November 1931. He obtained his M.D. degree (styled B.M., BCh., Oxon.) in 1955 and D.M. degree in 1963 at Oxford University, where he served on the Psychology Faculty from 1964, before relocating to the United States in 1967. He held Professorships in both neurology and psychology at Duke University and the University of Toronto, and he headed the Behavioral Neurology Research Division at the Shriver Center in Boston, Massachusetts. He also served as Presidents of the International Neuropsychological Society and the Society for Philosophy and Psychology. Kinsbourne died in Winchester, Massachusetts on 21 April 2024, at the age of 92. Work Kinsbourne was the first to identify and systematically describe the infant disorder "opsoclonus myocl ...

Cerebral Cortex
The cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is the largest site of Neuron, neural integration in the central nervous system, and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness. The six-layered neocortex makes up approximately 90% of the Cortex (anatomy), cortex, with the allocortex making up the remainder. The cortex is divided into left and right parts by the longitudinal fissure, which separates the two cerebral hemispheres that are joined beneath the cortex by the corpus callosum and other commissural fibers. In most mammals, apart from small mammals that have small brains, the cerebral cortex is folded, providing a greater surface area in the confined volume of the neurocranium, cranium. Apart from minimising brain and cranial volume, gyrification, cortical folding is crucial for the Neural circuit, brain circuitry ...

Hostility
Hostility is seen as a form of emotionally charged aggressive behavior. In everyday speech, it is more commonly used as a synonym for anger and aggression. It appears in several psychological theories. For instance it is a Facet (psychology), facet of neuroticism in the Revised NEO Personality Inventory, NEO PI, and forms part of personal construct psychology, developed by George Kelly (psychologist), George Kelly. Hostility/hospitality For hunter gatherers, every stranger from outside the small tribal group was a potential source of hostility. Similarly, in archaic Greece, every community was in a state of hostility, latent or overt, with every other community - something only gradually tempered by the rights and duties of hospitality. Tensions between the two poles of hostility and hospitality remain a potent force in the 21st century world. Us/them Robert Sapolsky argues that the tendency to form in-groups and out-groups of Us and Them, and to direct hostility at the latter ...

Emotion
Emotions are physical and mental states brought on by neurophysiology, neurophysiological changes, variously associated with thoughts, feelings, behavior, behavioral responses, and a degree of pleasure or suffering, displeasure. There is no scientific consensus on a definition. Emotions are often reciprocal determinism, intertwined with mood (psychology), mood, temperament, personality psychology, personality, disposition, or creativity. Research on emotion has increased over the past two decades, with many fields contributing, including psychology, medicine, history, sociology of emotions, computer science and philosophy. The numerous attempts to explain the origin, functional accounts of emotion, function, and other aspects of emotions have fostered intense research on this topic. Theorizing about the evolutionary origin and possible purpose of emotion dates back to Charles Darwin. Current areas of research include the neuroscience of emotion, using tools like positron ...

Prefrontal Cortex
In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the cerebral cortex. It is the association cortex in the frontal lobe. The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47. This brain region is involved in a wide range of higher-order cognitive functions, including speech formation (Broca's area), gaze ( frontal eye fields), working memory ( dorsolateral prefrontal cortex), and risk processing (e.g. ventromedial prefrontal cortex). The basic activity of this brain region is considered to be orchestration of thoughts and actions in accordance with internal goals. Many authors have indicated an integral link between a person's will to live, personality, and the functions of the prefrontal cortex. This brain region has been implicated in executive functions, such as planning, decision making, working memory, personality expression, moderating ...

Capacity Theory
Capacity theory is the theoretical approach that pulled researchers from Filter theories with Kahneman's published 1973 study, ''Attention and Effort'' positing attention was limited in overall capacity, that a person's ability to perform simultaneous tasks depends on how much "capacity" the jobs require. Further researchers - Johnson and Heinz (1978) and Navon & Gopher (1979) - went further with Kahneman's study. Shalom Fisch used Kahneman's capacity theory, just as others did for their research, to publish a paper on children's understanding of educational content on television. It is a communication theory based on a model which is used to explain and predict how children learn from educational television programming. It is formed by combining cognitive psychology Cognitive psychology is the scientific study of human mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. Cognitive psychology originated in the 1960s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frontal Lobe
The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a Sulcus (neuroanatomy), groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral sulcus (Sylvian fissure). The most anterior rounded part of the frontal lobe (though not well-defined) is known as the frontal pole, one of the three Cerebral hemisphere#Poles, poles of the cerebrum. The frontal lobe is covered by the frontal cortex. The frontal cortex includes the premotor cortex and the primary motor cortex – parts of the motor cortex. The front part of the frontal cortex is covered by the prefrontal cortex. The nonprimary motor cortex is a functionally defined portion of the frontal lobe. There are four principal Gyrus, gyri in the frontal lobe. The precentral gyrus is directly anterior to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negative Affectivity
In psychology, 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 (emotion), guilt, fear, and Anxiety, 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.
