Developmental Sequences and Theories

The Evolution of Attachment

The evolution of attachment follows this sequence:

• Preference for members of the same species.
• Typical preferences for caregivers.
• Clear preference for attachment figures and rejection of strangers.
• Development of some independence from attachment figures.

Motor and Cognitive Development

Proximodistal Law: A child develops the muscles of the elbow first and then the wrist.

Longitudinal Design: Uses a single sample from which it takes several measurements at different time points.

Attachment Characteristics: Attachment is characterized by behavior, mental models, and feelings.

Graphic Expression: The development of graphic expression is driven by maturation and social processes.

Preschool

Reliability and Validity in Selection

The quality of selection depends on using appropriate instruments. Predictors must be valid and reliable to successfully integrate employees.

Reliability

Reliability refers to the consistency of an instrument. It is used to ensure that the same results are obtained in successive applications under the same conditions.

• Test-Retest: Measures stability by comparing results over time. A higher coefficient indicates greater reliability.
• Internal Consistency: Measures the degree of homogeneity within the contents of the instrument.

Validity

Validity refers to the accuracy and precision of a measure.

Empirical Validity

• Concurrent: Determines the relationship between the predictor and the criterion at the same moment. It

Early Concepts of Intelligence

In psychology, the concept of intelligence has evolved over time and is defined in different ways according to various authors.

Francis Galton: Biological Fitness

One of the first was Francis Galton (19th century), who defined intelligence as a general biological fitness, determined by genetic factors considered unmodifiable. Galton thus argued that education and teaching could not change this inherent intelligence.

Binet and Simon: The First IQ Test

In the 20th century, Binet and Simon published the first modern intelligence test. Its main objective was to identify students needing help to meet school requirements. In collaboration with Simon, Binet published revisions of his intelligence scale.

Factorial Theories

Psychological Therapies

Definition:

It is a working relationship between a therapist and a client to develop more satisfying ways of being in the world.

Treatment Techniques:

1. Psychoanalysis: Sigmund Freud

   • Concept of Pathology: Instinctual conflicts that are beyond the reach of consciousness.
   • Objectives: To reveal the meaning of the unconscious.

   • Techniques:

     1. Free Association:

        The patient informs the therapist of their thoughts and memories that come to mind, regardless of their perceived importance. This facilitates the surfacing of repressed memories and desires for conscious acceptance.

     2. Interpretation of Dreams:

        Repressed desires during wakefulness are manifested in dreams in a disguised form.

     3. Transference:

        The patient transfers to the therapist hostility,

Principal Component Analysis for Change Detection

When applied to Principal Component Analysis (PCA) to detect changes, a multitemporal file is generated with the bands corresponding to the two dates. PCA is then applied to this file. The primary components collect image stability, while the secondary components recognize the information that does not change. Two common techniques used in this context are multitemporal regression and change vectors.

Scatter Plots and Band Correlation

A scatter plot (dispersograma) is used to analyze the correlation between bands and assist in band selection. It reveals the presence of clusters. For instances of no apparent reflectance, factors include vertical observation of the atmosphere. Without a reflector,...

Situational Factors in Attraction

These factors are necessary for the emergence of a relationship.

Physical or Spatial Proximity

Proximity is a necessary precondition for attraction to develop between two people. It provides the opportunity to discover shared interests. Key aspects include:

• Accessibility: People who are physically closer are more accessible.
• Friendship Formation: Proximity makes it more likely to create a friendship.
• Familiarity: We are taught from a young age not to deal with strangers; proximity increases familiarity, which in turn increases attraction.

In the early stages of a relationship, physical presence can decisively influence whether further contact occurs. In sporadic...

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

Foundations of Psychological Thought

The controversy surrounding fundamental psychological problems stems from the differing ways various schools of thought define the nature of human beings.

Behaviorism: Skinner, Thorndike, and Watson

This school focuses on observable and measurable behavior through experimental and observational methods. Key concepts include:

• Stimulus-response mechanisms.
• Application of animal behavior studies to human behavior.
• Objectivity in the description and prediction of behavior.

Structuralism: Wundt and Titchener

Structuralism emphasizes the introspective study of human reports. Key aspects include:

• Analyzing the structure of consciousness, consisting of sensations, images, and feelings.
• The practice of looking inward.
• Separating

Classification of Journalistic Genres

Journalistic genres can be broadly categorized based on their primary focus:

• Informational: This genre sticks strictly to facts, without expressing judgment or opinion. Examples include news reports, factual interviews, and objective reports.
• Hybrid: Combines factual information with the reporter's views or interpretations. Examples include columns and chronicles.
• Opinion-Based: Expresses a specific point of view or opinion on an event or news. Examples include articles and editorials.

Understanding the Interview Process

An interview consists of a conversation between a reporter and an interviewee, conducted to gather information or opinions of public interest.

Challenges of Telephone Interviews

While telephone interviews are a chosen research method, they present several distinct disadvantages:

• It is often unknown where the phone is located, potentially affecting the interviewee's environment.
• The presence of other individuals in the room cannot be ascertained, which might influence responses.
• It is more difficult to gauge the interviewee's comfort or willingness to answer questions, impacting data quality.
• Some problems are general to telephone surveys, while others are specific to the subject matter being discussed.
