Agonism and Antagonism: Quantification

Agonism and Antagonism: Quantification

When drugs are administered, they can elicit either an agonist or antagonist effect on the body. Agonism occurs when a drug activates a specific receptor, triggering a biological response. On the other hand, antagonism happens when a drug binds to the same receptors but blocks their activation, thereby preventing a biological response.
To quantify these effects, researchers use a dose-response curve, which provides valuable information about the potency and efficacy of a drug. Potency refers to...

Aggression

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Desensitization and Tachyphylaxis

Desensitization and Tachyphylaxis

Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

Three Developmental Domains

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Reliability and Validity

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Lazarus's Cognitive Appraisal Theory

Lazarus's Cognitive Appraisal Theory

Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

Summary

This study introduces a new Agonistic scale to measure sexual violence, suggesting it exists on a continuum rather than distinct categories. The psychometrically sound scale aids in understanding harassment and coercion.

Area of Science:

Psychology
Criminology
Sociology

Background:

Sexual violence encompasses diverse behaviors from harassment to homicide.
Current legal frameworks categorize these acts separately.
The Agonistic Continuum model proposes a unified construct underlying these behaviors.

Purpose of the Study:

To develop and validate a psychometric scale measuring the Agonistic Continuum.
To provide a tool for assessing sexual violence severity.
To challenge arbitrary categorizations of sexual violence.

Main Methods:

Classical test theory, exploratory factor analyses, taxometric analyses, and item response theory.
Data collected from a combined sample of MTurk workers and university students.
Development and testing of a 30-item Agonistic scale.

Main Results:

The 30-item Agonistic scale demonstrated sound psychometric properties.
Evidence supports the Agonistic Continuum model.
The scale effectively measures the severity of sexual violence.

Conclusions:

The new Agonistic scale offers a more nuanced understanding of sexual violence.
Findings support moving beyond discrete categories of sexual violence.
Implications for research on harassment and coercion, especially post-#MeToo.
