The stimulus–response model is a conceptual framework in psychology that describes how individuals react to external stimuli.According to this model, an external stimulus triggers a reaction in an organism, often without the need for conscious thought.
When the ISI is shorter, for example between two flashing lines alternating back and forth, we perceive the change in stimuli to be movement. [1] Wertheimer discovered that the space between the two lines is filled in by our brains and that the faster the lines alternate, the more likely we are to perceive it as one line moving back and forth.

Fear appraisals are the mental evaluations made in response to experiencing fear-inducing stimuli and are also known as threat appraisals. Fear appeal literature is primarily focused on understanding key fear appraisal processes in humans, with the intention of using it to drive social campaigns and behavioural interventions.
External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response. In order for a stimulus to be detected with high probability, its level of strength must exceed the absolute threshold ; if a signal does reach threshold, the information is transmitted to the central nervous system (CNS), where ...
Stimulus–response (S–R) compatibility is the degree to which a person's perception of the world is compatible with the required action. S–R compatibility has been described as the "naturalness" of the association between a stimulus and its response, such as a left-oriented stimulus requiring a response from the left side of the body.
All organisms, and apparently all cell types, sense and respond to mechanical stimuli. [6] MSCs function as mechanotransducers capable of generating both electrical and ion flux signals as a response to external or internal [7] stimuli. [8] Under extreme turgor in bacteria, non selective MSCs such as MSCL and MSCS serve as safety valves to ...

For example, the hippocampus is believed to be involved in spatial and declarative memory, as well as consolidating short-term into long-term memory. Studies have shown that declarative memories move between the limbic system, deep within the brain, and the outer, cortical regions. These are distinct from the mechanisms of the more primitive ...
