Summary
Cognitive function predicts dual-task performance in adults, regardless of age or hearing ability. This finding highlights the importance of cognitive assessments for understanding listening effort and speech-in-noise challenges.
Area of Science:
- Cognitive psychology
- Audiology
- Neuroscience
Background:
- Dual-task procedures assess cognitive load and listening effort.
- Standardized cognitive assessments and age-related changes in dual-task performance require further investigation.
- Data across aging populations are needed to understand performance trends.
Purpose of the Study:
- To investigate if cognitive function predicts dual-task performance in adults with and without hearing loss.
- To explore the relationship between cognitive abilities and performance on complex listening tasks.
Main Methods:
- Two age groups (30-50 and 60-80 years) with normal hearing were tested.
- Participants completed cognitive subtests (Woodcock-Johnson III) and hearing evaluations.
- Three perceptual-cognitive dual-task conditions were administered, involving auditory and visual processing.
Main Results:
- Cognitive function was found to predict dual-task performance.
- This predictive relationship held true irrespective of participants' age or hearing status.
Conclusions:
- Cognitive function is a significant predictor of dual-task performance, particularly in speech-in-noise scenarios.
- Further research on cognitive subtests' predictive value for listening effort is recommended.

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

01:24Revisionist Views of Adolescent and Adult Cognition
307
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

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...

The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...
