Research Environments: Field and Laboratory Settings

Research environments can be in the field or the laboratory.

Core Approaches to Scientific Research

• Empiricism
• Dialectical Materialism
• Positivism
• Phenomenology
• Structuralism

Integration of Qualitative and Quantitative Methods

The qualitative and quantitative approaches are complementary and enrich research; they are complemented or replaced in some cases:

1. Carry out observation and evaluation of phenomena.
2. Lay down assumptions or ideas as a consequence of observation and assessment.
3. Test and demonstrate the degree to which assumptions or ideas are unfounded.
4. Review such assumptions or ideas on the basis of evidence or analysis.
5. Propose new observations and assessments to establish, modify, cement, substantiate

Scientific Hypothesis Formulation and Feyerabend's View

A hypothesis is an assumption about what happens in the world. The scientific method does not establish how a scenario arises or how it occurs to the scientist. In the formulation of hypotheses, factors come into play that may seem unscientific:

• Imagination
• Invention
• Chance
• Luck

Paul Feyerabend extends the influence of the imagination to all scientific procedure. He argues that the revolutionary discoveries of modern science are made possible by the freedom and spontaneity of scientific activity. To constrain scientific activity to a series of fixed steps makes science rather dogmatic and sterile. Feyerabend argues it is an illusion to think that these scientific discoveries are the result...

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.

Techniques of Control Activation

Objective: To teach the individual to control their own level of arousal through the direct modification of physiological conditions without the aid of external resources.

Techniques utilized:

• Progressive relaxation
• Autogenic training
• Passive relaxation
• And more...

Applications: Disorders associated with excessive activation or stress, pain problems, preparation for hospitalization, and various medical interventions.

Technical Exposure

Objective: Reduction of anxiety through the repeated presentation of the stimulus that causes anxiety.

Applications: The elimination of medical fears, phobias, and caution regarding blood and injections.

Operating Techniques to Acquire or Increase Behavior

Objective: To increase the probability... Continue reading "Behavioral Modification Techniques for Psychological Health" »

Humanistic theory C. Rogers developed a humanistic psychology whose primary purpose was to understand and improve personalidad.Reconoció that person's conduct is conditioned by:-The constitution biological-social forces, "Past experiences. But also defended personal liberty: In the theory of C. Rogers is crucial concept: Self: the configuration is consistent organized perceptions, values and ideals that form the image.

Direct observation is to collect and record information in a systematic and structured, the occurrence and duration of spontaneous behaviors of some people 2. Clinical Interview: A method...

Item 2: Behavioral Concepts

1. Define Learning

Learning is the process by which experience produces a permanent change in knowledge or behavior.

3. Define Key Behavioral Terms

• Punishment: A consequence that, immediately after a behavior, lowers the probability that the conduct is repeated.
• Reinforcement: Defined as an event presented immediately after the occurrence of a behavior that increases the likelihood that the conduct is repeated.

Positive Reinforcement

This means that when presented, it increases the chances for a response to occur again. Example: Giving points for participating in class makes a student repeat participation.

Negative Reinforcement

These are consequences that, when removed from the situation, increase the likelihood that the... Continue reading "Behavior Modification: Learning, Reinforcement, and Punishment Principles" »

Human Development: Progress and Well-being

Human development focuses directly on the progress of life and well-being; it is an evaluation of life. Human development is linked to strengthening specific skills related to the whole range of things a person can be and do in life. This involves the possibility for all people to increase their human potential fully and utilize that capacity in all areas—cultural, economic, and political—that is, in capacity-building.

Human development is about freedom to live as one likes.

Human development has to do with the expression of civil liberties and is associated with the possibility that all individuals are subjects and beneficiaries of development; that is, they are constituted as subjects.

Modifications

Perceived Conflict

Any conflict must be perceived; the degree of perception may reveal alternative solutions. While conflict solutions are theoretically unlimited, they are only possible when the situation is viewed within its proper context.

Conflict Sense

Perceptual processes can create or avoid conflicts through feelings and attitudes. When a conflict affects emotions and becomes personalized, it is defined as Conflict Sense—a phenomenon frequently observed in married couples.

Manifest Conflict

Manifest conflict occurs when both parties recognize the differences that prevent an agreement. When there is a conscious attempt to block the achievement of a counterparty's goals, the behavior is viewed as manifest conflict, which can escalate to verbal...

Sensation and Perception Fundamentals

• Sensation: The process of receiving information about the physical world through our sensory receptors.
• Perception: The process of selecting, organizing, and interpreting information from our sensory receptors.
• Sensory Receptors: Specialized cells responsible for transduction, converting physical energy into nerve impulses.
• Transduction: The conversion of physical energy into electrical signals by receptor cells.
• Absolute Thresholds: The smallest amount of a stimulus one can detect 50% of the time.
• Signal Detection Theory: Suggests that absolute thresholds for sensation are dependent on both physical energy and internal factors.
• Difference Threshold: The minimum amount of change in a stimulus required for a person

Psychoanalysis

Created by Sigmund Freud, psychoanalysis seeks to study psychology from an "internal" point of view; that is, it explores the human unconscious as the cause of virtually all human behavior. Psychoanalysis is based on free association and has utilized various techniques such as:

• Hypnosis
• Rorschach test (inkblot test)
• Dream interpretation

Since the original formulation by Freud, there has been much controversy regarding psychoanalysis, even among psychoanalysts themselves. Of particular note is the later contribution of Jacques Lacan.

Behaviorism

Behaviorism is a discipline that studies psychology by referring to the human body as if it functioned like a machine. In this view, the body issues a response to a stimulus; for example, if... Continue reading "Core Perspectives and Schools of Psychology" »
