Summary
This study investigated cognitive control and its relationship with uncertainty tolerance (UT) and need for cognitive closure (NCC). Findings suggest minimal correlation between cognitive control measures and these individual difference variables.
Area of Science:
- Psychology
- Cognitive Science
Background:
- Cognitive control is crucial for goal-directed behavior, involving decision-making amidst distractions and adapting to conflicting information.
- Individual differences in cognitive control are linked to psychopathology, but the relationship with uncertainty tolerance (UT) remains unexplored.
- UT and cognitive control both relate to performance in ambiguous situations, suggesting potential overlap.
Purpose of the Study:
- To examine the relationship between cognitive control, uncertainty tolerance (UT), and need for cognitive closure (NCC).
- To investigate if individual differences in UT and NCC correlate with established measures of cognitive control.
Main Methods:
- Two web-based experiments utilized a flanker task to assess cognitive control.
- Behavioral indices, including congruency effects (CEs) and congruency-sequence effects (CSEs), were measured.
- Participants included N=111 in Experiment 1 and N=116 in Experiment 2.
Main Results:
- Small-to-zero correlations were found between congruency effects (CEs), uncertainty tolerance (UT), and need for cognitive closure (NCC).
- A subtle correlation (r=.18) was observed between NCC and congruency-sequence effects (CSEs) in Experiment 2.
- Bayesian analyses generally supported the null hypotheses, indicating limited evidence for a relationship.
Conclusions:
- Cognitive control, as measured by CEs and CSEs, shows minimal association with uncertainty tolerance and need for cognitive closure.
- The findings suggest that these constructs, while related to ambiguity, may operate through distinct mechanisms.
- Further research is needed to fully elucidate the complex interplay between cognitive control and individual difference variables.

Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

The transfer function is a fundamental concept in the analysis and design of linear time-invariant (LTI) systems. It offers a concise way to understand how a system responds to different inputs in the frequency domain. It serves as a bridge between the time-domain differential equations that describe system dynamics and the frequency-domain representation that facilitates easier manipulation and analysis.

83.1K
All the digits in a measurement, including the uncertain last digit, are called significant figures or significant digits. Note that zero may be a measured value; for example, if a scale that shows weight to the nearest pound reads “140,” then the 1 (hundreds), 4 (tens), and 0 (ones) are all significant (measured) values.
