It is theorized that the brain works in a set sequence, as does a computer. The sequence goes as follows, "receives input, processes the information, and delivers an output". This theory suggests that we as humans will process information in a similar way. Like a computer receives input the mind will receive information through the senses. If ...
Two-alternative forced choice (2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input. For example, to determine a person's sensitivity to dim light, the observer would be presented with a ...
In social science, force-field analysis provides a framework for looking at the factors ("forces") that influence a situation, originally social situations. It looks at forces that are either driving the movement toward a goal (helping forces) or blocking movement toward a goal (hindering forces).
An example of the second type of discrimination paradigm, which administers stimuli successfully or serially, is a classic 1963 study in which participants are given two sequentially lifted weights and asked to judge whether the second was heavier or lighter than the first.
The force entity that is in focus is called the agonist and the force entity opposing it is the Antagonist (see a, figure 1). In the example, the door is the agonist and the force preventing the door from being opened is the Antagonist. Force entities have an intrinsic force tendency, either toward action or toward
Stevens' power law is an empirical relationship in psychophysics between an increased intensity or strength in a physical stimulus and the perceived magnitude increase in the sensation created by the stimulus.
[4] [5] Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). [5] The following process connects a person's concepts and expectations (or knowledge) with restorative and selective mechanisms, such as attention, that influence perception.
In cognitive psychology, attention and working memory have also been conceptualized as relying on two distinct processes. [3] Whether the focus be on social psychology or cognitive psychology, there are many examples of dual process theories produced throughout the past. The following just show a glimpse into the variety that can be found.
