Lamarckian Evolutionary Theory

Lamarck proposed the first theory suggesting that nature follows an ascending order. He argued that the diversity of species is due to changes in the behavior of living things and the need for adaptation, rather than geological catastrophes as previously believed. Lamarck formulated his theory on two principles:

• Law of Use and Disuse: Organisms develop or atrophy organs based on how frequently they are used.
• Law of Inheritance of Acquired Characteristics: These physical changes are transmitted to offspring, explaining how one species evolves into another.

The Process of Hominization

Hominization is defined as the process of morphological, psychological, and social evolution that enabled the appearance of the human... Continue reading "Lamarckian Evolution and the Process of Hominization" »

Basic Components of Development

• Affective Development: The capacity for emotion, controlling emotions, feelings, and passions.
• Cognitive Development: The evolution experienced by a person in notional components, intellect, and personality.
• Social Development: The process by which a person, from childhood, will cultivate skills and knowledge that will make them an active and mature member of their society.
• Moral Development: Achieving their own personal behavior, responsive to values, norms, rules, and customs accepted by the social environment in which the person grows.
• Motor Development: Development that examines changes in human motor skills from birth to old age, the factors involved in these changes, and their relation to other areas of

Understanding Human Behavior in Organizations

1. People plan, organize, direct, and control.
2. The Human Resource Administration (ARH) intends to treat people as individuals and as important organizational resources.
3. Organizations are composed of people, groups, and organizations.
4. Factors that impact human behavior include personality, learning, motivation, perception, and values.
5. Three approaches to studying human behavior are: man as a transactor, man whose conduct is directed at a target, and the open system model.
6. Motivation is what drives a person to act in a certain way, originating a propensity toward a specific behavior.
7. The three principles explaining human behavior are: behavior is caused, motivated, and oriented toward goals.
8. The motivational

Early Study of Non-Verbal Signals

Since 1914 to 1940, there was considerable interest in how people communicate through facial expressions.

Disciplines in Communication Study

The investigation of communication draws from 5 disciplines: psychology, psychiatry, anthropology, sociology, and ethology.

Culture Shapes Non-Verbal Cues

We take for granted premises about masculinity and femininity that originate from culture. Human culture can provide behavior patterns consistent or not consistent with the gender of the individual. Conventions, such as how people dress or style their hair, also help convey cultural norms.

Gender, Culture, and Behavior Patterns

Studies of three different tribes showed variations in gender roles. In one, both sexes were ferocious... Continue reading "Understanding Non-Verbal Communication Research" »

Scope and Limits of Corpus Formation

Formation of a shared corpus by psychologists: selection and hierarchy of criteria according to the public. Theoretical and methodological explanations advance in a clear direction.

Limits:

• Generally qualitative
• Primarily fit-adaptive systems assessed by the extent to which they describe and explain behavior

The Experimental Method in Psychology

Aims to discover the effects of one variable on another.

• Dependent variables: Observed behavior or effect.
• Independent variables: The treatment manipulated by the researcher.

Beginning with a scientifically solvable problem, a hypothesis is proposed and empirically verified (numerically). During the experiment, data collection is performed using measuring instruments.

Limitations:

Understanding Motivation: Definition and Core Concepts

Motivation is the reason or purpose for which an individual feels the impulse to act in a certain way and achieve a goal. Sometimes there are several causes for the same behavior, and sometimes one cause creates several behaviors.

The Motivation Process

The motivation process is a personal feeling that the individual experiences. While internal, it occurs externally through behavior. One can speak of motivation as a process involving five key stages:

1. Need: A need is born.
2. Tension: An imbalance between what we want and what we have.
3. Impetus (Impulse): An impulse arises that leads to trying to satisfy the created need.
4. Behavior: The individual performs an action to cover the need.
5. Satisfaction: The

Perspectives on Cultural Diversity

When individuals encounter beliefs, behaviors, and customs different from their own, they react in various ways. There are several distinct positions regarding cultural diversity:

1. Ethnocentrism

This is the attitude of judging and valuing the culture of other groups based on the criteria or beliefs of one's own culture. From this perspective, one's own culture is considered superior, leading to the criticism of different or foreign elements. This attitude serves as the foundation for phenomena such as imperialism and colonization.

2. Racism

Racism refers to any belief, attitude, or behavior based on the conviction that certain races are superior to others, often classifying other groups as subhuman. It manifests... Continue reading "Understanding Cultural Diversity: Key Perspectives and Attitudes" »

Foundations of Gestalt Therapy

The Gestalt approach has been influenced by several key areas:

• Freud's psychoanalysis
• Existential philosophy
• Phenomenology
• Gestalt psychology, particularly its theory of perception (figure-ground, the law of fitness)
• Eastern religions (Buddhism, Zen)
• Psychodrama
• The theory of muscular armor (W. Reich)
• The theory of Indifference (Sigmund Kretschmer, Friedlander)

Key Concepts in Gestalt Therapy

Contact and Awareness: Key concepts upon which Gestalt therapy is based include:

• The outside world: Sensory contact with objects and events occurring in the present moment (what I see, touch, and so on, right now).
• The inner world: Sensory contact with internal events, such as muscular tension, uncomfortable sensations, tremors, sweating,

Emotional Reactions to Health Loss

Emotional reactions to the loss of health are frequent and varied. Common reactions include:

• Anxiety: Feelings of worry or fear.
• Aggressiveness: Displays of rage.

When faced with unpleasant emotions, people often employ psychological strategies known as defense mechanisms. These are automatic, unconscious reactions to emotionally challenging situations, designed to help individuals cope.

Common Defense Mechanisms

• Denial: Refusing to acknowledge the reality of the situation.
• Manic Defense: Reacting with excessive excitement or happiness to mask distress. These two mechanisms are common initially but tend to fade as the illness becomes more apparent.
• Repression: Suppressing awareness of the illness.
• Regression: Adopting

Language Localization and Brain Areas

Language localization: Identification of circuits involved in language-related activities within the hemispheres. The Wernicke-Geschwind model influences the cortical localization of language.

Wernicke's Area

An area of the left temporal cortex; Wernicke's area is considered the center of language comprehension.

Expressive Language

Concerning the production of language, related to writing or speaking.

Broca's Aphasia

A disorder of speech production without a deficit related to language comprehension. For example, a patient asked about a dental appointment responds with choppy and unintelligible speech: "Yes ... Monday ... and Dick Pope ... Wednesday at nine o'clock in the morning ... and at ten in the morning... Continue reading "Language Localization: Broca's and Wernicke's Areas Explained" »
