Reduction Semantics and Word Generalization

Reduction semantics refers to how children initially connect the few words they know to specific meanings. This involves using a word in a narrower sense, such as calling only their own pet "dog." Later, semantic extension or generalization occurs, where the same name is applied to a series of objects with similar shapes, such as calling every round object a "ball" or everything with wheels a "car."

Identifying Emotional Distress and Hearing Issues

When should one suspect severe emotional distress or hearing problems in children? If a baby does not respond to babbling or words by the age of one, they must undergo a hearing test. Furthermore, an unwillingness to communicate at an appropriate age can be... Continue reading "Early Childhood Development: Language and Emotions" »

Social Interaction and Human Responsibility

Social interaction is the responsibility of thinking and feeling human beings. Differences in this experience can be dramatic, impacting significant aspects of life such as government, religion, marriage, and education.

Defining the Learning Process

Learning is defined as a relatively permanent change in behavior resulting from practice. While all learning implies a change in behavior, not every change in behavior constitutes learning.

Key Behavioral Theories

• Skinner: His theory is based on the analysis of behavior, explaining learning through responses and incentives. This allows for behavior modification using positive reinforcement (reward) versus negative reinforcement (punishment).
• Pavlov: He discovered

Programs to Improve Intelligence

In modern psychology, intelligence remains a complex construct consisting of a set of mental processes and behavioral performances.

Origins of Programs to Improve Intelligence

• Social Studies
• Educational Studies
• Scientific Studies

Programs that teach people how to think assume that individuals differ in their intellectual potential. These differences are mainly due to skill factors and are, therefore, subject to change and improvement through training.

Major Programs to Improve Intelligence

Instrumental Enrichment Program (PEI)

The Instrumental Enrichment Program (PEI) (Feuerstein, 1980) is based on the theories of structural cognitive modifiability and mediated learning. It stands out for defining intelligence as a process... Continue reading "Effective Methods for Enhancing Human Intelligence" »

Functional Anatomy of the Cerebral Cortex

The cerebral cortex is divided into four lobes, which are named after the cranial bones that are closest and are: frontal, parietal, temporal, and occipital. In the prefrontal areas, distinctions can be made between those related to the processing of sensory information as well as motor commands. These areas are called primary, secondary, or tertiary depending on the level of information processing.

Localization of Cognitive Functions

Cognitive functions are localized in specific areas of the brain. However, this does not mean that cognitive function is mediated solely by a single region of the brain; it is more correct to say that certain areas are more involved than others in developing a type of function....

Chapter I — Introduction to Psychology

Psychology is the scientific study of behavior and mental processes; it includes not only what people do but also their biological activities, feelings, perceptions, memory, reasoning, and thoughts.

Where Psychologists Work

Psychologists are employed in various settings. Although the major sites are private practice and universities, many are found in hospitals, clinics, community mental health centers, and counseling centers.

Historical Foundations

Wilhelm Wundt established the foundations of psychology in Germany in 1879.

Early Perspectives

The first perspectives of psychology were structuralism, functionalism, and Gestalt theory.

Emphasis on Prevention and Diversity

Psychology is increasingly specializing... Continue reading "Foundations of Psychology: History, Methods, and Ethics" »

Types of Reinforcement

Bandura identifies three forms of reinforcement that promote learning by observation:

1. Direct Reinforcement: Reinforcing the observer directly when they reproduce the model's behavior.

2. Indirect or Vicarious Reinforcement: Reinforcing the model. Observing the consequences of others' behavior can modify behavior similarly to direct experience. Vicarious reinforcement:

• a) Informs observers about appropriate behavior based on success and failure patterns.
• b) Enhances practical learning through direct experience, as multiple observers can be exposed to the modeled behavior simultaneously.
• c) Reduces attention demands compared to direct experience.

3. Self-Reinforcement: Controlling one's own reinforcements without expecting... Continue reading "Observational Learning: Reinforcement and Classroom Application" »

Sensory Thresholds and Psychophysics

Sensory thresholds. Psychophysics studies the relationship between the physical nature of a stimulus and the sensory responses that occur in a person. Our ability to detect stimuli relies on different sensory thresholds:

• Absolute threshold: the minimum amount of stimulus we need to be aware of something and also the maximum amount of stimulation we can tolerate.
• Differential threshold: the difference in stimulus intensity needed to notice an increase or decrease prior to the stimulus.

Cognitive theory. Cognitive psychology researches how people process information and how these processes are represented in the world, and how these representations determine behavior. The terms feeling and perception are related... Continue reading "Sensory Thresholds, Perception and Optical Illusions" »

Observation: Concepts and Features

Observation is an inherent part of human nature, integrated into our psychology in relation to everyday events. It involves the perception of a phenomenon that is selected and recorded without manipulation, making the observer a passive witness of what has occurred.

Observation can vary in its degree of systematization, ranging from casual observation to those that adhere to strict methodological criteria.

Observation becomes a scientific technique when it meets the following criteria:

• It is part of an objective investigation.
• It is stated and recorded systematically.
• It is subject to checks and controls regarding validity and reliability.

Types of Observation

Self-Observation

Self-observation occurs when the observer... Continue reading "Understanding Observation: Types and Techniques" »

Vygotsky and the Crisis of Psychology (1896-1934)

During the period of 1896-1934, the Crisis of Psychology emerged because no existing school was conducive to the methods of observation, measurement, and testing alongside psychoanalysis. This era provided the basis for a theory regarding the processes of human psychology. Seeking an approximation to describe and explain brain mechanisms within a social context, Development Practice is based on Marxism and the historical changes that occur in society and material life.

The Origin of Higher Psychological Functions

Sociocultural theory posits that higher psychological functions originate from historical-social interaction. These functions are mediated by structure and language, involving subconscious... Continue reading "Vygotsky's Sociocultural Theory of Cognitive Development" »
