"The executive system is a theorized cognitive system in psychology that controls and manages other cognitive processes. It is responsible for processes that are sometimes referred to as the executive function, executive functions, supervisory attentional system, or cognitive control. However, executive function and cognitive control are not synonymous with an executive system with the former potentially carried out by specific brain areas or networks (e.g., anterior cingulate cortex and prefrontal cortex in attention, cf. Botvinick et al., 2001; see also Verguts & Notebaert, 2009). The concept is used by psychologists and neuroscientists to describe a loosely defined collection of brain processes that are responsible for planning, cognitive flexibility, abstract thinking, rule acquisition, initiating appropriate actions and inhibiting inappropriate actions, and selecting relevant sensory information."

"A cognitive bias is a pattern of deviation in judgment that occurs in particular situations. Implicit in the concept of a ""pattern of deviation"" is a standard of comparison; this may be the judgment of people outside those particular situations, or may be a set of independently verifiable facts. Cognitive biases are instances of evolved mental behavior. Some are presumably adaptive, for example, because they lead to more effective actions in given contexts or enable faster decisions when faster decisions are of greater value. Others presumably result from a lack of appropriate mental mechanisms, or from the misapplication of a mechanism that is adaptive under different circumstances. Cognitive bias is a general term that is used to describe many observer effects in the human mind, some of which can lead to perceptual distortion, inaccurate judgment, or illogical interpretation."

"Mental chronometry is the use of response time in perceptual-motor tasks to infer the content, duration, and temporal sequencing of cognitive operations. Mental chronometry is studied using the measurements of reaction time (RT). Reaction time is the elapsed time between the presentation of a sensory stimulus and the subsequent behavioral response. In psychometric psychology it is considered to be an index of speed of processing. That is, it indicates how fast the thinker can execute the mental operations needed by the task at hand. In turn, speed of processing is considered an index of processing efficiency. The behavioral response is typically a button press but can also be an eye movement, a vocal response, or some other observable behavior." More... |

"A psychological reward is a process that reinforces behavior - something that, when offered, causes a behavior to increase in intensity. Reward is an operational concept for describing the positive value an individual ascribes to an object, behavioral act or an internal physical state. Natural rewards include those that are necessary for the survival of species, such as eating, drinking, sex, and fighting. Secondary rewards derive their value from the primary reward, and include shelter, money, pleasant touch, beauty, music, etc. The functions of rewards are based directly on the modification of behavior and indirectly on the sensory properties of rewards. For instance, altruism may induce a larger psychological reward, although it doesn't cause sensations. Rewards are generally considered more effective than punishment in enforcing positive behavior. Rewards induce learning, approach behavior and feelings of positive emotions." More... |

Attitudes are generally positive or negative views of a person, place, thing, or event- this is often referred to as the attitude object. People can also be conflicted or ambivalent toward an object, meaning that they simultaneously possess both positive and negative attitudes toward the item in question. " More... |

Perception is not the passive receipt of these signals, but can be shaped by learning, memory and expectation.

"Psychomotor agitation is a series of unintentional and purposeless motions that stem from mental tension and anxiety of an individual. This includes pacing around a room, wringing one's hands, pulling off clothing and putting it back on and other similar actions. In more severe cases, the motions may become harmful to the individual, such as ripping, tearing or chewing at the skin around one's fingernails or lips to the point of bleeding. Psychomotor agitation is a symptom typically found in major depressive disorder or obsessive-compulsive disorder, and sometimes the manic phase in bipolar disorder, although it can also be a result of an excess intake of stimulants. The middle aged and the elderly are more at risk to express this condition." More... |

"In psychology and psychiatry, anhedonia is defined as the inability to experience pleasure from activities formerly found enjoyable, e.g. hobbies, exercise, social interaction or sexual activity. As a clinical symptom in depression, anhedonia rates highly in making a diagnosis of this disorder. The Diagnostic and Statistical Manual of Mental Disorders (DSM) describes a ""lack of interest or pleasure"" but these can be hard to tell apart given that people become less interested in things which do not give them pleasure. The DSM criterion of weight loss is probably related to it and many depressed people with this symptom describe a lack of enjoyment of food. People suffering from anhedonia in association with depression generally feel good in the morning and unhappy in the evenings and can portray any of the non-psychotic symptoms and signs of depression."

Insomnia is most often defined by an individual's report of sleeping difficulties. Insomnia is typically followed by functional impairment while awake. One definition of insomnia is difficulties initiating and/or maintaining sleep, or nonrestorative sleep, associated with impairments of daytime functioning or marked distress for more than 1 month. Hypersomnia is a disorder characterized by excessive amounts of sleepiness. Hypersomnia can be caused by brain damage and disorders such as clinical depression. Insomnia affects at least 80% of depressed people. Hypersomnia, or oversleeping, can also happen, affecting 15% of depressed people." More... |

"Somatic symptoms are common in patients with MDD, including fatigue and lack of energy and painful physical symptoms such as headaches and back pain. According to an analysis of data from the World Health Organization, 69% of patients in primary care settings meeting the DSM-IV/ICD-10 criteria for depression presented somatic symptoms as their primary reason for seeking medical care. Somatic symptoms in depressed patients, in particular painful physical symptoms, are associated with more severe depression of longer duration and greater functional impairment, poorer clinical outcome and higher health-care costs. Furthermore, the overlap of somatic symptoms associated with depression with other medical illnesses can impact accurate diagnosis and lead to the under-recognition of depression and misdiagnosis (Vaccarino et al, 2008; PMID: 18280580)."

"In cardiology, the QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle. In general, the QT interval represents electrical depolarization and repolarization of the left and right ventricles. A prolonged QT interval is a biomarker for ventricular tachyarrhythmias like torsades de pointes and a risk factor for sudden death." More... |

"The baroreflex or baroreceptor reflex is one of the body's homeostatic mechanisms for maintaining blood pressure. It provides a negative feedback loop in which an elevated blood pressure reflexively causes heart rate and, thus, blood pressure to decrease; in similar fashion, decreased blood pressure activates the baroreflex, causing heart rate and, thus, blood pressure to rise."

Child abuse can occur in a child's home, or in the organizations, schools or communities the child interacts with. There are four major categories of child abuse: neglect, physical abuse, psychological/emotional abuse, and child sexual abuse. Child abuse (physical, emotional, sexual, or neglect) is also associated with increased risk of developing depressive disorders later in life. Such a link has good face validity given that it is during the years of development that a child is learning how to become a social being. Abuse of the child by the caregiver is bound to distort the developing personality and create a much greater risk for depression and many other debilitating mental and emotional states." More... |
