An analysis of the various forms of stimuli

Organism The characteristics of life Since there is no unequivocal definition of life, most current definitions in biology are descriptive. Life is considered a characteristic of something that preserves, furthers or reinforces its existence in the given environment. This characteristic exhibits all or most of the following traits: Living things require energy to maintain internal organization homeostasis and to produce the other phenomena associated with life.

Behavior Behavior refers to the movement of some part of an organism that changes some aspect of the environment.

Operant conditioning Operant behavior is the so-called "voluntary" behavior that is sensitive to, or controlled by its consequences. Specifically, operant conditioning refers to the three-term contingency that uses stimulus controlin particular an antecedent contingency called the discriminative stimulus SD that influences the strengthening or weakening of behavior through such consequences as reinforcement or punishment.

Respondent classical conditioning[ edit ] Main article: Classical conditioning Respondent classical conditioning is based on innate stimulus-response relationships called reflexes. In his famous experiments with dogs, Pavlov usually used the salivary reflex, namely salivation unconditioned response following the taste of food unconditioned stimulus.

Pairing a neutral stimulus, for example a bell conditioned stimulus with food caused the bell to elicit salivation conditioned response. Thus, in classical conditioning, the conditioned stimulus becomes a signal for a biologically significant consequence.

The Argument

Note that in respondent conditioning, unlike operant conditioning, the response does not produce a reinforcer or punisher e. Environment[ edit ] The environment is the entire constellation of stimuli in which an organism exists.

A stimulus is an "energy change that affects an organism through its receptor cells". Topographically by its physical features.

Temporally by when it occurs. Functionally by its effect on behavior. Reinforcement Reinforcement is the key element in operant conditioning [41] and in most behavior change programs. If a behavior is followed closely in time by a stimulus and this results in an increase in the future frequency of that behavior, then the stimulus is a positive reinforcer.

If the removal of an event serves as a reinforcer, this is termed negative reinforcement. Punishment psychology Punishment is a process by which a consequence immediately follows a behavior which decreases the future frequency of that behavior.

As with reinforcement, a stimulus can be added positive punishment or removed negative punishment. Broadly, there are three types of punishment: Extinction procedures are often preferred over punishment procedures, as many punishment procedures are deemed unethical and in many states prohibited.

Nonetheless, extinction procedures must be implemented with utmost care by professionals, as they are generally associated with extinction bursts. These novel behaviors are a core component of shaping procedures.

Discriminated operant and three-term contingency[ edit ] In addition to a relation being made between behavior and its consequences, operant conditioning also establishes relations between antecedent conditions and behaviors.

In other words, the relation between a behavior B and its context A is because of consequences Cmore specifically, this relationship between AB because of C indicates that the relationship is established by prior consequences that have occurred in similar contexts.

A behavior which occurs more frequently in the presence of an antecedent condition than in its absence is called a discriminated operant. The antecedent stimulus is called a discriminative stimulus SD.The design of a questionnaire will depend on whether the researcher wishes to collect exploratory information (i.e.

qualitative information for the purposes of better understanding or the generation of hypotheses on a subject) or quantitative information (to test specific hypotheses that have.

Why do we have dreams and what do they mean? These questions have for centuries been the subject of a debate that has recently become the center of a heated controversy. Other articles where Stimulus is discussed: aggressive behaviour: Physiological causes of aggression: inevitably triggered by a particular stimulus or by collections of stimuli. Depending on the internal state of the potential attacker, the same opponent may be attacked on one occasion but ignored on another. In particular, an individual’s tendency to attack a rival is influenced by the. In the nervous system, internal and external stimuli can elicit two different categories of responses: an excitatory response, normally in the form of an action potential, and an inhibitory response.

For example, if you touch a hot stove (US), you remove your hand quickly (UR). Everyday we are bombarded with various forms of stimuli. We see many people, we hear cars drive by, we feel the cool breeze, etc, but how can we prove that we are really experiencing these stimuli?

That is the question that Rene Descartes asked some three hundred fifty years ago, is there a. Occurs when special receptors in the sense organs are activated, allowing various forms of outside stimuli to become neural signals in the brain.

The most primitive part of our human brain is referred to as the “Primal Brain”. Although it controls the most complex of life-sustaining functions such as breathing, heart rate, etc., it is remarkably simple in terms of what types of stimuli trigger its attention.
