Working Memory01:24

Working Memory

1.2K
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...

Cognitive Therapy01:25

Cognitive Therapy

1.4K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Rational Emotive Behavior Therapy

658
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

Information Processing Approach01:30

Information Processing Approach

793
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...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

847
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.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Cognitive deficits are a primary feature of schizophrenia and related psychotic disorders, significantly impacting daily functioning.
  • Behavioral interventions show promise for cognitive remediation, but optimizing delivery for cost-effectiveness is crucial.

Purpose of the Study:

  • To evaluate a novel, internet-delivered cognitive remediation (CR) program focused on working memory.
  • To assess the impact of this CR training, supplemented by weekly telephone support, on cognitive difficulties.

Main Methods:

  • A non-randomized study involving 56 participants diagnosed with psychosis.
  • Participants received either 8 weeks of CR training (approx. 20 hours) or treatment as usual (TAU).
  • Cognitive functions, including general cognitive ability, working memory, and episodic memory, were assessed pre- and post-intervention.

Main Results:

  • CR training led to significant improvements in trained working memory tasks.
  • Participants in the CR group also showed significant gains in verbal episodic memory.
  • No significant changes in general cognitive ability were observed; effect sizes for memory improvements were comparable to in-person training.

Conclusions:

  • Internet-based working memory training demonstrates efficacy as a cognitive remediation therapy for individuals with psychosis.
  • The study highlights the potential of accessible, internet-delivered interventions while acknowledging implementation challenges.
