Understanding Hypotheses and Variables

The word "hypothesis" has Greek roots: thesis, which means "what goes", combined with hypo, a particle meaning "under." So, a hypothesis is "what goes underneath."

Assumptions and Variables

Assumptions are theoretical statements, unverified, but likely references to variables or the relationship between variables. So, what is a variable? A variable is an observable characteristic of something. Variables are subject to change or variation, adopting different values. They can be categorized and are interrelated. Scientific research revolves around them.

The Role of Variables in Research

The purpose of scientific work is to discover the existence and magnitude of variables and to test the relationships that bind... Continue reading "Understanding Hypotheses and Variables in Research" »

Understanding Scientific Research

Scientific research is a systematic process that applies the scientific method to seek information relevant to understanding, verifying, correcting, or applying knowledge. It is the deliberate search for knowledge or solutions to scientific problems. The scientific method indicates the path to follow in this investigation and the techniques needed to traverse it. It is a process consisting of various steps, stages, or phases, interconnected in a logical, sequential, and dynamic manner to generate knowledge.

Key Types of Research

• Historical Research

  Describes what was. This method applies not only to history but also to natural sciences, law, medicine, or any other scientific discipline.

• Descriptive Research

  Interprets

Bureaucracy and Ideal Type Dysfunctions

Max Weber developed the first interpretation of the emergence of modern organizations. For him, organizations are a way of coordinating the activities of human groups or management of the goods they produce. Developing organizations depends on controlling information. Organizations have a strong hierarchy, where power tends to be concentrated at the top. According to Weber, all large organizations tend to be bureaucratic. Bureaucracy means "office desk to write," or "rule." Accordingly, bureaucracy means "government officials." Bureaucracy is often associated with paperwork and inefficiency. However, other authors have dealt with this reality from another point of view, as a model of care, precision, and... Continue reading "Max Weber's Bureaucracy: Ideal Type and Dysfunctions" »

A] Creative Imagination

The Imagination and Fantasy

Fantasy, as opposed to reality, is a fundamental element of our psyche. Freudian psychoanalysis emphasized the importance of the pleasure principle, and his disciple, Roheim, highlighted the role of fantasy in this principle, particularly the fantasy of magic. This magical thinking appears to be the earliest form of imagination in children and is crucial for development. Fantasy plays a significant role not only in the structure of imagination but also in personality development. Kant referred to fantasy as the imagination's unintentional production of images.

B] Definitions

• Evocation: The ability to reproduce past situations or states of consciousness without specific reference to past time.
• Eidetic

Short-Term Memory

Short-term memory is the center of consciousness, encompassing all thoughts, experiences, or information within a given period. Its duration is typically 15 to 20 seconds, or a maximum of 30 seconds. After this period, information is lost if not consolidated.

Information must be consolidated from short-term memory to long-term memory. Conversely, retrieving information from long-term memory requires transferring it back to short-term memory for use.

Long-Term Memory

Long-term memory is the lifelong repository of all the information we accumulate. Due to its unlimited capacity and duration, it is the richest and most complex memory structure, but also the most challenging to investigate.

While short-term memory is based on the physical... Continue reading "Understanding Memory: Short-Term, Long-Term, and Disorders" »

Brain Structure and Function

The brain is the most important organ of the nervous system. Weighing approximately 1200 grams, it consists of two hemispheres. It is responsible for motor actions in response to stimuli and hormonal reactions. The brain comprises:

Neocortex (Cerebral Cortex)

Processes information, prepares responses, and is responsible for reasoning. It is divided into 4 lobes with distinct features:

• Frontal (association)
• Temporal (auditory)
• Occipital (visual)
• Parietal (sensory, motor)

Mesocortex (Limbic System)

Plays an important role in psychic life and in regulating functions that affect emotional life in general.

Paleocortex

Governs the operation of very basic aspects such as sleep or appetite.

Ethnocentrism and Cultural Relativism

Ethnocentrism is the belief that one's own culture is the center of the world, in the sense that all other cultures are classified according to their degree of approximation to the mainstream culture. Ethnocentrism has sometimes been presented as a scientific doctrine, as the Nazis attempted to establish rigorous biological criteria to distinguish different races. A graphic illustration of the critique of ethnocentrism is provided by the anthropologist Claude Lévi-Strauss when he says that "The savage is he who calls another savage."

Although ethnocentrism is a critical concept, not all human cultures are comparable because there are significant differences between their cultural traits. While no culture... Continue reading "Ethnocentrism and Cultural Evolution: Understanding Differences" »

Cognitive psychology is a discipline that studies processes such as perception, memory, language, attention, and other processes involved in the handling of information by the subject.

Piaget's Theory of Cognitive Development

Jean Piaget is known for his genetic theory of cognitive development, which proposes that children actively construct their understanding of the world through interaction.

Intelligence, according to Piaget, is the ability to maintain a constant adaptation of the subject's schemas to the world in which they operate.

Adaptation explains the development process of learning and is divided into two sub-processes:

• Assimilation: Integrating new information or experiences into existing schemas. For example, understanding a new concept
