Cognitive Learning01:21

Cognitive Learning

975
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
Tolman introduced the idea that behavior is influenced by...

Visual Agnosia01:12

Visual Agnosia

899
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Metacognition01:26

Metacognition

677
Metacognition is a conscious process where individuals are aware of their cognitive and executive processes, such as planning before solving a problem or self-monitoring during reading. For instance, a writer may need help with composing a piece. The situation involves a writer who is working on a piece of writing, but while doing so, they realize that something is missing. They notice that their characters lack depth or details. This realization occurs because the writer is reflecting on their...

Sensory Modalities01:15

Sensory Modalities

3.7K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Cognition and Behavior01:23

Cognition and Behavior

282
Social psychology examines the complex interplay between individual mental processes and social interactions. Historically, the field was divided into two domains: social behavior and social cognition. Researchers focusing on social behavior analyzed actions within social contexts, such as conformity, aggression, or cooperation. Meanwhile, social cognition researchers investigated how people perceive, interpret, and mentally represent their social environments. However, modern perspectives no...

Cognitivism01:17

Cognitivism

2.7K
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...

    • Robotics
    • Cognitive Science

    Background:

    • Visual navigation is crucial for embodied agents in large environments.
    • Intelligent behavior relies on cognitive abilities like memory and reasoning.

    • Demonstrated significant performance improvements in image-goal navigation tasks.
    • The framework effectively integrates heterogeneous cognitive modalities (memory and reasoning).
    • The approach leverages semantic relationships and object sequences for better navigation.

    Conclusions:

    • The proposed SMCG framework offers an effective approach to integrate memory and reasoning for intelligent visual navigation.
    • Hierarchical cognition extraction enhances the utilization of cognitive cues within the SMCG.
    • This unified semantic-level representation advances the capabilities of embodied agents in complex environments.
