Cognitivism01:17

Cognitivism

2.9K
Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Introduction to Cognitive Psychology

2.7K
Cognitive psychology is the field of psychology dedicated to examining how people think. It attempts to explain how and why we think the way we do by studying the interactions among human thinking, emotion, creativity, language, and problem-solving, as well as other cognitive processes. Cognitive psychology studies how information is processed and manipulated in remembering, thinking, and knowing.
This field emerged in the mid-20th century, following a period dominated by behaviorism, which...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

926
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.

Psychosis: Goals of Pharmacotherapy

706
Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Drug Therapy01:28

Drug Therapy

449
The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

324
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Area of Science:

  • Neuroscience
  • Pharmacology
  • Clinical Neurology

Background:

  • Neurologic disorders, especially brain injury, often cause significant cognitive deficits.
  • Cognitive activators are compounds investigated for their potential to ameliorate these deficits.
  • Existing research presents various drug classes and assessment strategies.

Purpose of the Study:

  • To review compounds classified as cognitive activators for treating cognitive deficits.
  • To examine the efficacy of various drug interventions, including catecholamine agonists, cholinergic agonists, nootropics, gangliosides, and thyrotropin releasing hormone (TRH).
  • To discuss and recommend sensitive measures for assessing treatment efficacy.

Main Methods:

  • Literature review of studies on cognitive activators and their effects on cognitive-behavioral functioning.
  • Analysis of different approaches to assess treatment efficacy: physiological, psychometric, and behavioral measures.
  • Synthesis of findings from the authors' own work and other investigators.

Main Results:

  • Cognitive activators show potential in addressing cognitive deficits associated with neurologic disorders.
  • A critical evaluation of assessment methodologies is presented, distinguishing sensitive from less sensitive measures.
  • Specific recommendations for sensitive physiological, psychometric, and behavioral measures are provided.

Conclusions:

  • Cognitive activators represent a promising therapeutic avenue for cognitive impairments post-brain injury.
  • Careful selection of sensitive outcome measures is crucial for accurately evaluating treatment efficacy.
  • Further research integrating these findings can advance the clinical application of cognitive activators.
