Comprehensive Notes on Emotional Development and Developmental Psychology Theories

Overview of Major Developmental Theories

  • Psychoanalytic Theories: Freud and Erikson     - Sigmund Freud’s Psychosexual Stages:         - Proposes universal developmental stages tied to specific erogenous zones.         - Oral Stage (01year0-1\,year): The primary focus is early nourishment; the id operates under the pleasure principle.         - Ego Development: Emerges later in the first year, representing reason and mediation with reality.         - Anal Stage (age2age\,2): Focuses on toilet training and control.         - Phallic Stage (36years3-6\,years): Focuses on the genitals and the development of the Superego, which involves the internalization of parents’ standards for acceptable behavior.         - Latency Stage (612years6-12\,years): A period of dormant sexual feelings.         - Genital Stage (13+years13+\,years): Focuses on mature sexual interests.     - Erik Erikson’s Psychosocial Stages:         - Identified 88 stages, each associated with a specific crisis or conflict (e.g., Trust vs. Mistrust).     - Theoretical Weaknesses: Both theories are often criticized for being too vague to be empirically tested.     - Lasting Influence: Freud contributed to modern attachment theory, cognitive science, and neuroscience; Erikson remains influential in adolescent research regarding identity development.

  • Learning Theories     - Watson’s Behaviorism: Demonstrated through the "Little Albert" experiment, showing how fear can be conditioned.     - Skinner’s Operant Conditioning: Focused on reinforcement and punishment.         - Attention as Reinforcement: Negative behaviors can be maintained by attention; "time outs" are used to remove this reinforcement.         - Intermittent Reinforcement: Demonstrated by the supermarket example (giving in to a tantrum occasionally makes the behavior harder to extinguish).         - Behavior Modification Therapy: The application of these principles to change behavior.     - Social Learning Theory (Albert Bandura): Emphasized Vicarious Learning through observation, famously demonstrated by the Bobo Doll experiment.

  • Theories of Social Cognition     - These theories emphasize self-socialization.     - Selman’s Stage Theory of Role Taking:         - 1.1. Realizing others have different perspectives.         - 2.2. Realizing different perspectives are not always due to a lack of information.         - 3.3. Being able to systematically compare different perspectives.         - 4.4. Taking the perspective of the ‘generalized other’.     - Dodge’s Information-Processing (IP) Theory of Social Problem Solving:         - Analyzes the role of cognition on social behavior, particularly aggressive behavior and the hostile attributional bias (interpreting neutral actions as hostile).     - Dweck’s Theory of Self-Attributions and Achievement Motivation:         - Incremental/Growth Mindset: Focusing on learning goals.         - Entity/Fixed Mindset: Focusing on performance goals.         - Praising children differently leads to different achievement motivations.

  • Ecological Theories     - Ethological and Evolutionary Theories:         - Ethological View: Behavior patterns in animals (e.g., imprinting) are shaped by evolution just like physical traits.         - Evolutionary View: Based on Darwinian concepts; adaptive genes shaped current behaviors. Large brains allow for high neural plasticity, leading to a tradeoff: a prolonged childhood.         - Play: Serves as a platform for learning.         - Parental Investment Theory: Includes concepts like the Cinderella Effect.     - Bronfenbrenner’s Bioecological Model: Five systems influence development:         - Microsystem: Immediate environment (family, school).         - Mesosystem: Connections between components of the microsystem.         - Exosystem: Indirect environments (e.g., a parent’s flexible or remote working hours).         - Macrosystem: Social and cultural values (e.g., national laws).         - Chronosystem: Changes over time (e.g., the rise of technology use).

Emotional Development and the Marshmallow Test

  • The Marshmallow Test (Mischel, 2015)     - A study on the ability to delay gratification.     - Coping Strategies for Waiting:         - Distraction Techniques: Talking, singing, making up games, or trying to sleep.         - Focused Attention: Staring directly at the treat (often leads to failure to wait).     - Findings:         - Some children prefer a guaranteed, immediate reward over a larger future reward.         - The ability to delay gratification is linked to self-control and willpower.     - Longitudinal Success: Early self-control predicted success later in life.         - Performance in the task predicted SAT scores (Eigstietal.,2006Eigsti\,et\,al.,\,2006) and higher educational levels (Ayduketal.,2000Ayduk\,et\,al.,\,2000).     - Conclusion: Emotions are basic to human experience, but learning to regulate them has long-term consequences.

Defining Emotions and Feelings

  • Distinguishing Terms (McLaren, 2024)     - Emotion: A physiological experience or state of awareness that provides information about the world.     - Feeling: The conscious awareness of the emotion itself.

  • Components of Emotion (Izard, 2010)     - Emotions are combinations of physiological and cognitive responses to thoughts or experiences, consisting of five components:         - 1.1. Neural Responses: The brain processing information.         - 2.2. Physiological Factors: Heart rate, breathing rate, and hormone levels (e.g., a racing heart).         - 3.** **Subjective Feelings:** The internal experience of fear or joy.\n        - 4.** Emotional Expressions: Visible signs like raised eyebrows or a mouth pulled back.         - 5.** **Desire to Take Action:** The urge to escape, approach, or change the environment (e.g., running away from a dog).\n- **Key Developmental Questions:**\n    - Do we experience physiological reactions and then label them, or do we assess a situation cognitively first?\n    - Are emotions innate or learned?\n    - How does cognition influence emotional experience?\n\n# Theories of Emotional Development\n\n- **Discrete Emotions Theory**\n    - Proposed by **Charles Darwin (1872)** in *The Expression of the Emotions in Man and Animals*.\n    - Emotions are biologically and neurologically innate, evolved for adaptation.\n    - Emotions are basic, automatic, and universal across all people, including infants.\n    - **Definition:** Each emotion has a specific and distinctive set of bodily and facial reactions.\n    - **Evidence:**\n        - Infants express recognizable, discrete emotions before being taught them (Izard\,et\,al.,\,2010).\n        - Facial expressions are similar worldwide (Ekman\,\&\,Cordaro,\,2011).\n        - Vocalizations of basic emotions (anger, joy) are recognized across diverse cultures (Sauter\,et\,al.,\,2010).\n\n- **Functionalist View on Emotions**\n    - Developed by researchers like **Campos et al. (1994)andSaarnietal.()** and **Saarni et al. (2006)**.\n    - Emotions help individuals manage relationships with their environment.\n    - Emotions are not discrete; they vary based on the social environment and are goal-driven.\n    - **Role of Action:** The function of emotions is to promote actions that achieve goals.\n    - **Examples:**\n        - **Disgust:** Goal is avoiding contamination/illness; meaning is "this may make me ill"; action is rejection.\n        - **Fear:** Goal is maintaining integrity; meaning is "this is threatening"; action is flight or withdrawal.\n        - **Anger:** Goal is attaining an end state; meaning is "there is an obstacle"; action is forward movement to eliminate the obstacle.\n\n# The Emergence of Basic Emotions\n\n- **The Six Basic Emotions:** Happiness, fear, anger, sadness, surprise, and disgust.\n    - These are universal, serve survival/communication, and emerge early in life.\n- **The AFFEX System:**\n    - Used for coding basic emotions in infants by linking facial muscle movements to specific emotions (Izard\,\&\,Dougherty,\,1980).\n    - **Specific Facial Indicators:**\n        - **Sadness:** Mouth corners turned down, lips pressed/trembling, brow slightly furrowed.\n        - **Surprise:** Eyes wide open, eyebrows arched, mouth in a round "O" shape.\n        - **Happiness:** Smiling (open or closed mouth), raised cheeks causing squinting.\n        - **Anger:** Furrowed brow forming an "X" shape, square-shaped mouth (sometimes teeth), flared nostrils.\n        - **Disgust:** Wrinkled nose, flared nostrils, mouth wide open with lips pulled back, sometimes tongue sticking out.\n        - **Fear:** Eyes wide open, brows raised in the center (triangle shape), mouth pulled back into a grimace.\n\n- **Developmental Milestones of Basic Emotions**\n    - **Happiness:**\n        - **First Month:** Smiles primarily during REM sleep or when stroked (reflexive, not social).\n        - **3-8\,weeks:** Smiles in response to external stimuli (touch, high voices).\n        - **3\,months(sometimes(sometimes6-7\,weeks):** **Social Smiles** directed toward people.\n        - **3-4\,months:** Laughter during pleasurable activities like tickling.\n    - **Fear:**\n        - **First Months:** Little evidence of distinct fear reactions.\n        - **7\,months:** Initial signs of fear and recognition of fear in others.\n        - **Fear of Strangers:** An early adaptive form of fear; infants rely on parents for protection. Braungart-Rieker (2010)foundnofearat) found no fear at4\,months,asignificantincreaseat, a significant increase at8\,months,andstabilityuntil, and stability until16\,months.\n    - **Separation Anxiety:**\n        - Emerges around 8\,months; involves distress when the caregiver leaves.\n        - Tends to decline around 15\,months((Kagan,\,1976).\n        - Universal across cultures (U.S., Israeli kibbutzim, !Kung San groups).\n    - **Anger:**\n        - Adaptive for self-defense and goal-directed behavior.\n        - By 1st\,birthday,infantsclearlyexpressanger(, infants clearly express anger (Lemerise\,\&\,Dodge,\,2008).\n        - Peaks at 18-24\,months((Cole\,et\,al.,\,2011).\n        - Declines between 3-6\,yearsduetoincreasedlanguageskillsandregulationskills(due to increased language skills and regulation skills (Kopp,\,1992).\n    - **Sadness:**\n        - Occurs in situations similar to anger but is less frequent by preschool years. It helps draw support from caregivers.\n    - **Surprise:**\n        - Not a "startle" reflex (which is present at birth). Surprise requires cognitive understanding and emerges by 6\,months.\n        - Often transforms quickly into other emotions like happiness.\n    - **Disgust:**\n        - Evolutionary purpose to avoid toxins. Children learn disgust by observing adults.\n        - Before 3-4\,years, children use words like "yucky" since they don't understand the word "disgust."\n\n# Self-Conscious Emotions and Beyond\n\n- **Self-Conscious Emotions:**\n    - Include guilt, shame, jealousy, empathy, pride, and embarrassment.\n    - Unlike basic emotions, these require a sense of self as separate from others, typically emerging around 2\,years\,of\,age.\n    - Represents **discontinuous growth** (a sudden shift).\n    - Influenced by awareness of societal standards and how others judge them.\n- **Understanding Others' Emotions:**\n    - **3\,months:** Infants distinguish happiness, surprise, and anger (demonstrated via **habituation paradigm**).\n    - **7\,months:Infantsdiscriminatefearandsadness;brainwavepatternsdifferwhenobservingfearfulvs.angryfaces(:** Infants discriminate fear and sadness; brain wave patterns differ when observing fearful vs. angry faces (Kobiella\,et\,al.,\,2008).\n    - **Social Referencing:** By 12\,months, infants use parental facial/vocal cues specifically to navigate ambiguous situations (staying close if parent shows fear, approaching if happy).\n- **Environmental Factors:**\n    - Exposure to adversity (e.g., orphaned children in Sierra Leone) can enhance sensitivity to anger while decreasing recognition of sadness as an adaptation for self-preservation.\n    - Low emotion recognition ability at 6\,years is linked to high levels of loneliness.\n- **Real vs. Fake Emotions:**\n    - **Display Rules:** Informal norms about when and how to express or suppress emotions.\n    - **3-year-olds:** Can attempt to mask negative emotions (e.g., hiding disappointment over a gift), though it is often obvious.\n    - **5-year-olds$$:** Show significant improvement in understanding and producing false emotions for social politeness.
