Psychosexual Stages of Personality: Oral

Psychosexual Stages of Personality: Oral

The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Parental Care

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Instinctive Drift

Instinctive Drift

Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

Area of Science:

Behavioral science
Developmental psychology
Obesity research

Background:

Motivation to eat, measured by effort for food, correlates with obesity.
High food reinforcement is associated with increased calorie consumption, mediating obesity risk.
Early infant feeding behaviors, like avid sucking, predict later adiposity.

Purpose of the Study:

To review methods for measuring food reinforcement in infants and young children.
To present novel prenatal and postnatal predictors of infant food reinforcement.
To propose mechanisms underlying the developmental trajectory of food reinforcement.

Main Methods:

Review of existing literature on food reinforcement measurement.
Synthesis of research on early feeding behaviors and adiposity.
Exploration of potential developmental pathways for food reinforcement.

Main Results:

Food reinforcement is a significant predictor of obesity across the lifespan.
Early life factors, including prenatal and postnatal influences, are associated with infant food reinforcement.
Energy intake plays a mediating role in the food reinforcement-obesity relationship.

Conclusions:

Understanding the origins of food reinforcement is crucial for early obesity prevention.
Prenatal and postnatal environments may shape infant food reinforcement.
Further research is needed to elucidate the developmental trajectory and underlying mechanisms of food reinforcement.
