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...

Actor-Observer Effect01:23

Actor-Observer Effect

345
The actor-observer effect, a cognitive bias closely linked to the fundamental attribution error, refers to the tendency for individuals to attribute their behavior to external, situational factors while explaining others’ behavior in terms of internal, dispositional traits. This asymmetry in attribution significantly influences social perception and judgment.Cognitive Mechanisms Behind the EffectTwo primary psychological mechanisms contribute to the actor-observer effect: differences in...

The Influence of Cognition on Affect01:29

The Influence of Cognition on Affect

190
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...

Observational Learning01:12

Observational Learning

841
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Causes of Social Behavior II: Cognitive Processes

190
Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...

Cognitive Theories: Schachter-Singer Theory of Emotion01:20

Cognitive Theories: Schachter-Singer Theory of Emotion

1.5K
Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.
Physiological Arousal and Cognitive Labeling
According to this theory, when an individual experiences...

Area of Science:

  • Cognitive psychology
  • Computational modeling
  • Gerontology

Background:

  • Repeated cognitive assessments provide valuable data for understanding cognitive performance.
  • Current methods often focus on extracting cognitive markers but do not fully leverage them for outcome prediction.

Purpose of the Study:

  • To introduce and demonstrate a partially observable predictor modeling approach.
  • To integrate cognitive markers and demographic covariates for predicting clinically relevant outcomes.

Main Methods:

  • Developed a Bayesian multilevel modeling framework for predictive process modeling.
  • Simultaneously extracted cognitive markers from repeated assessment data.
  • Combined learning features and demographic variables to predict mild cognitive impairment.

Main Results:

  • The partially observable predictor approach successfully integrates cognitive markers and demographic data.
  • Demonstrated the utility of this approach in predicting mild cognitive impairment using real-world data.
  • The model effectively links cognitive performance features to clinical outcomes.

Conclusions:

  • The proposed modeling approach enhances the predictive utility of cognitive markers.
  • This framework offers a valuable tool for predicting clinical outcomes such as mild cognitive impairment.
  • Facilitates a deeper understanding of individual differences in cognitive aging and disease prediction.
