| reinforcement | 1. <neurology> An increase of force or strength; denoting specifically the increased sharpness of the patellar reflex when the patient at the same time closes the fist tightly or pulls against the flexed fingers or contracts some other set of muscles. See: Jendrassik's manoeuvre. 2. <dentistry> A structural addition or inclusion used to give additional strength in function; e.g., bars in plastic denture base. 3. <psychology> In conditioning, the totality of the process in which the conditioned stimulus is followed by presentation of the unconditioned stimulus which, itself, elicits the response to be conditioned. See: reinforcer, schedules of reinforcement, classical conditioning, operant conditioning. (05 Mar 2000) |
|---|---|
| reinforcement schedule | <psychology> A schedule prescribing when the subject is to be reinforced or rewarded in terms of temporal interval in psychological experiments. The schedule may be continuous or intermittent. (12 Dec 1998) |
| reinforcement, verbal | Use of word stimulus to strengthen a response during learning. (12 Dec 1998) |
| primary reinforcement | Satisfaction of physiological needs or drives, such as that supplied by food or sleep. (05 Mar 2000) |
| secondary reinforcement | Reinforcement through something which, while it does not satisfy the need directly, has been associated with direct satisfaction of the need, such as the effect on behaviour of a food or beer commercial on television. (05 Mar 2000) |
| social reinforcement | <psychology> The strengthening of a response with a social reward such as a nod of approval, a parent's love or attention. (12 Dec 1998) |
| bone scan: falsely negative metastases | <radiology> Anaplastic tumours, reticulum cell sarcoma, renal cell carcinoma, thyroid carcinoma, histiocytosis, neuroblastoma, multiple myeloma (positive scan usually due to recent or impending fracture) (12 Dec 1998) |
| ventilators, negative-pressure | Body ventilators that assist ventilation by applying intermittent subatmospheric pressure around the thorax, abdomen, or airway and periodically expand the chest wall and inflate the lungs. They are relatively simple to operate and do not require tracheostomy. These devices include the tank ventilators ("iron lung"), portalung, pneumowrap, and chest cuirass ("tortoise shell"). (12 Dec 1998) |
| gram-negative | <microbiology> A common class of bacteria normally found in the gastrointestinal tract that can be responsible for disease in man (sepsis). Bacteria are considered to be gram-negative because of their characteristic staining properties under the microscope, where they either do not stain or are decolourised by alcohol during Gram's method of staining. This is a primary characteristic of bacteria that have a cell wall composed of a thin layer of peptidoglycan covered by an outer membrane of lipoprotein and lipopolysaccharide containing endotoxin. The gram staining characteristics of bacteria have resulted in an important classification system for the identification of bacteria. See: gram-positive (06 Oct 1997) |
| gram-negative aerobic bacteria | <microbiology> A large group of aerobic bacteria which show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative aerobic rods and cocci | <microbiology> A group of gram-negative bacteria consisting of rod- and coccus-shaped cells. They are both aerobic (able to grow under an air atmosphere) and microaerophilic (grow better in low concentrations of oxygen) under nitrogen-fixing conditions but, when supplied with a source of fixed nitrogen, they grow as aerobes. (12 Dec 1998) |
| gram-negative anaerobic bacteria | <microbiology> A large group of anaerobic bacteria which show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative anaerobic cocci | <microbiology> A group of anaerobic coccoid bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative anaerobic straight, curved, and helical rods | <microbiology> A group of anaerobic, rod-shaped bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-negative bacteria | <microbiology> Bacteria which lose crystal violet stain but are stained pink when treated by gram's method. (12 Dec 1998) |
| negative reinforcement |
Refers to an increase in the frequency of a response by removing an aversive event immediately after the response is performed.

| negative reinforcement |
Reward generated by the removal of painful or stressful conditions or events.

|
| negative reinforcement |
Encouraging a correct behavior by punishing any behaviors other than it. An example is putting a child into "time out" after she throws a tantrum. According to most adult learning research negative reinforcement is not recommended for most adult learning situations.
