Working Memory01:24

Working Memory

715
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Information Processing Approach

424
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Hindsight Biases

4.2K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

457
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

298
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

Cognitive Development During Adulthood01:30

Cognitive Development During Adulthood

701
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Area of Science:

  • Cognitive Psychology
  • Behavioral Economics

Background:

  • Performance in cognitive tasks is often assumed to reflect only ability.
  • The role of motivation in sustained task performance requires further investigation.

Purpose of the Study:

  • To investigate the impact of goal progress feedback on cognitive task performance.
  • To explore the relationship between feedback, motivation, and effort allocation.

Main Methods:

  • Two studies utilized a switching task paradigm.
  • Participants received goal progress feedback (remaining task portion) or no feedback.
  • Performance metrics, fatigue levels, and break durations were recorded.

Main Results:

  • Feedback group achieved higher asymptotic performance levels.
  • Participants receiving feedback reported less fatigue.
  • Shorter breaks between task blocks were observed in the feedback group.

Conclusions:

  • Asymptotic performance is influenced by both ability and motivation.
  • Goal progress feedback enhances cognitive performance by increasing motivation.
  • This feedback mechanism offers a cost-effective method to improve performance in educational and organizational settings.
