However, the learning potential from this task difficulty level will differ based on the: skill level of the performer; task complexity; task environment; Importantly, though increases in task difficulty may increase learning potential, increased task difficulty is also expected to decrease performance.
The model of hierarchical complexity (MHC) is a formal theory and a mathematical psychology framework for scoring how complex a behavior is. [4] Developed by Michael Lamport Commons and colleagues, [3] it quantifies the order of hierarchical complexity of a task based on mathematical principles of how the information is organized, [5] in terms of information science.
Intrinsic cognitive load is the inherent level of difficulty associated with a specific instructional topic. The term was first used in the early 1990s by Chandler and Sweller. [ 18 ] According to them, all instructions have an inherent difficulty associated with them (e.g., the calculation of 2 + 2, versus solving a differential equation ).
A desirable difficulty is a learning task that requires a considerable but desirable amount of effort, thereby improving long-term performance. It is also described as a learning level achieved through a sequence of learning tasks and feedback that lead to enhanced learning and transfer.
In psychiatry, derailment (aka loosening of association, asyndesis, asyndetic thinking, knight's move thinking, entgleisen, disorganised thinking [1]) categorises any speech comprising sequences of unrelated or barely related ideas; the topic often changes from one sentence to another.
Reliability provides a convenient index of test quality in a single number, reliability. However, it does not provide any information for evaluating single items. Item analysis within the classical approach often relies on two statistics: the P-value (proportion) and the item-total correlation (point-biserial correlation coefficient).
Cognitive complexity is a psychological characteristic or psychological variable that indicates how complex or simple is the frame and perceptual skill of a person.. A person who is measured high on cognitive complexity tends to perceive nuances and subtle differences while a person with a lower measure, indicating a less complex cognitive structure for the task or activity, does not.
Difficulty is considered a key predictor of behavior in psychology and is included in most recognized models of behavior change, such as the theory of planned behavior. Most of these models rely on people's perceptions and estimates of behavioral difficulty. That is, difficulty is considered to be subjective and person-dependent. [1]
