Critical Thinking II01:25

Critical Thinking II

Critical thinking is a cognitive process with several attributes. The attributes of critical thinking include the following:
Structure of Self01:29

Structure of Self

Sigmund Freud's model of the human psyche is often illustrated using an iceberg analogy. The iceberg's visible tip represents the conscious mind, which includes thoughts and perceptions that individuals are immediately aware of. However, the larger, submerged portion of the iceberg represents the unconscious mind, a reservoir of repressed desires, instincts, and memories. According to Freud, human behavior is primarily shaped by this hidden realm.
Components of the Mind: Id, Ego, and Superego
Reason and Intuition01:37

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...
Protecting Self-Esteem01:27

Protecting Self-Esteem

Self-esteem, a central component of psychological well-being, is actively maintained through various cognitive and behavioral strategies. Individuals employ specific mechanisms to preserve a positive self-concept and mitigate threats to their self-worth, particularly in contexts involving social evaluation or personal feedback. Four primary techniques are commonly used to sustain self-esteem.Manipulating AppraisalsOne prominent strategy involves manipulating appraisals from others. Individuals...
Cerebrum: Anatomical Overview II01:11

Cerebrum: Anatomical Overview II

Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...
Cognitive Dissonance01:38

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Area of Science:

  • Evolutionary biology
  • Human genetics
  • Neuroscience

Background:

  • Human intellectual and emotional capacities are complex traits.
  • Understanding the genetic basis of these traits is crucial for evolutionary studies.

Purpose of the Study:

  • To analyze human mutation rates in relation to genes essential for intellectual and emotional fitness.
  • To investigate the potential decline of these human abilities.
  • To explore the evolutionary origins and historical changes in human cognitive and emotional traits.

Main Methods:

  • Analysis of human mutation rates.
  • Assessment of the number of genes contributing to intellectual and emotional fitness.

Main Results:

  • Evidence suggests a probable loss of human intellectual and emotional fitness.
  • The study indicates a potential negative trend in these essential human abilities.

Conclusions:

  • The findings raise critical questions about the evolutionary trajectory of human cognition and emotion.
  • Further research is needed to pinpoint when and how these changes began.
