John O'Keefe FRS FMedSci (born November 18, 1939) is an American-British neuroscientist, psychologist and a professor at University College London.. O'Keefe discovered place cells in the hippocampus, and that they show a specific kind of temporal coding in the form of theta phase precession.
Eysenck's three-factor model of personality was a causal theory of personality based on activation of reticular formation and limbic system. The reticular formation is a region in the brainstem that is involved in mediating arousal and consciousness. The limbic system is involved in mediating emotion, behavior, motivation, and long-term memory.
Personality neuroscience uses neuroscientific methods to study the neurobiological mechanisms underlying individual differences in stable psychological attributes. . Specifically, personality neuroscience aims to investigate the relationships between inter-individual variation in brain structures as well as functions and behavioral measures of persistent psychological traits, broadly defined ...
The Spectrum Model: This model proposes that associations between personality and psychopathology are found because these two constructs both occupy a single domain or spectrum and psychopathology is simply a display of the extremes of normal personality function.
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus, and the subiculum are the components of the hippocampal formation located in the limbic system.
The integration of this information in the hippocampus makes the hippocampus a practical location for cognitive mapping, which necessarily involves combining information about an object's location and its other features. [19] O'Keefe and Nadel were the first to outline a relationship between the hippocampus and cognitive mapping. [8]
The social cognitive theory of personality views personality development in terms of reciprocal interactionism, that is, a perspective that considers the relationship of person-society as an interactive system that defines and molds personal development.
1861 – Paul Broca discovered an area in the left cerebral hemisphere that is important for speech production, now known as Broca's area, founding neuropsychology. 1869 – Francis Galton published Hereditary Genius, arguing for eugenics. He went on to found psychometrics, differential psychology, and the lexical hypothesis of personality.
