Modules 11-12: Development: Prenatal, Newborn, Infancy, and Childhood

  1. Stages of Prenatal Development

    • There are 3 stages:

      • Germinal Stage

      • Embryonic Stage

      • Fetal Stage

    • These stages are not the same as trimesters.

  2. Teratogen

    • Definition: A teratogen is any substance that can cause developmental malformations in a fetus.

    • Common teratogens include:

      • Alcohol

      • Nicotine

      • Certain infections (e.g., rubella)

      • Environmental pollutants (e.g., lead)

  3. Critical Period

    • Definition: A critical period is a specific timeframe during development when the presence or absence of certain stimuli has a profound effect on development.

  4. Object Permanence

    • Definition: Object permanence is the understanding that objects continue to exist even when they cannot be observed. This concept typically develops around 8 to 12 months of age.

  5. Fine vs. Gross Motor Skills

    • Fine motor skills involve small muscle movements (e.g., grasping, manipulating small objects).

    • Gross motor skills involve larger muscle groups (e.g., crawling, walking).

  6. Schema

    • Definition: A schema is a cognitive framework that helps organize and interpret information.

    • Assimilation vs. Accommodation:

      • Assimilation: Incorporating new experiences into existing schemas without changing them.

      • Accommodation: Changing existing schemas to incorporate new information.

  7. Piaget’s 4 Stages of Cognitive Development

    • Sensorimotor Stage

    • Preoperational Stage

    • Concrete Operational Stage

    • Studying Attachment: Typically studied using the Strange Situation procedure.

    • Types of Attachment Styles:

      • Secure Attachment: Child feels safe and can explore.

      • Insecure Avoidant: Child avoids closeness and does not seek comfort upon reunion.

      • Insecure Resistant: Child is clingy and dependent but is resistant to comfort during reunion.

  9. Temperament

    • Innate Temperament: Many researchers believe temperament is biologically based.

    • Three Categories of Temperament:

      • Easy: Adaptable and positive mood.

      • Difficult: Irregular in habits and negative mood.

      • Slow-to-Warm-Up: Inactive but can slowly adapt with a consistent environment.

    • Gender Identity: Personal sense of one's own gender.

    • Gender Expression: External manifestation of gender, expressed through clothing, behavior, etc.

    • Sexuality: Broad term including sexual orientation, desires, and preferences.

    • Sexual Orientation: Pattern of emotional, romantic, or sexual attraction to others.

  2. Primary vs. Secondary Sex Characteristics

    • Primary: Directly related to reproduction (e.g., ovaries, testes).

    • Secondary: Not directly involved in reproduction but distinguish male from female (e.g., breast development, body hair).

  3. Androgyny

    • Definition: A blend of both masculine and feminine traits in personality or behavior.

  4. Gender Typing

    • Definition: The process by which a child becomes aware of their gender and thus behaves accordingly by adopting gender-specific roles.

  5. Kinsey Scale

    • A scale that measures sexual orientation on a continuum, ranging from heterosexual to homosexual.

Module 17: Sensation and Perception

  1. Sensation vs. Perception

    • Sensation: The process of detecting physical energy from the environment (e.g., sights, sounds).

    • Perception: The process of organizing and interpreting sensory information.

  2. Top-Down vs. Bottom-Up Processing

    • Top-Down: Interpretation of sensory input guided by prior knowledge, experience, and expectations.

    • Bottom-Up: Processing begins with the sensory input itself and builds perceptions from this.

  3. Absolute vs. Difference Threshold

    • Absolute Threshold: The minimum intensity of a stimulus that can be detected 50% of the time.

    • Difference Threshold: The minimum difference between two stimuli that can be detected 50% of the time (also known as just noticeable difference or JND).

  4. Sensory Adaptation

    • Definition: Diminished sensitivity to a stimulus as a consequence of constant exposure to that stimulus.

  5. Perceptual Set

    • Definition: A mental predisposition to perceive one thing and not another based on expectations.

Module 18: Vision

  1. Light Characteristics

    • Wavelength: Determines the color of light (hue).

    • Amplitude: Determines the intensity or brightness of light.

  2. Parts of the Eye

    • Rods: Responsible for vision in low light; located mainly in the peripheral regions of the retina.

    • Cones: Responsible for color vision and detail; concentrated in the fovea (central part of the retina).

  3. Young-Helmholtz Trichromatic Theory vs. Opponent Processing Theory

    • Trichromatic Theory: Suggests that color perception is based on three primary colors: red, green, and blue.

    • Opponent Process Theory: Posits that color perception is controlled by the activity of two opponent systems: a blue-yellow mechanism and a red-green mechanism.

  4. Visual Information Processing

    • Steps include:

    1. Light enters the eye.

    2. Projects onto the retina.

    3. Photoreceptors (rods and cones) transform light into neural signals.

    4. Signals are processed through several layers of neurons.

    5. Information sent to the brain.

    • For detailed sequences, refer to figure 18.11 in the textbook.

  5. Monocular vs. Binocular Cues

    • Monocular Cues: Depth cues that require only one eye (e.g., texture gradient, interposition).

    • Binocular Cues: Depth cues that depend on the use of both eyes (e.g., retinal disparity).

  6. Visual Cliff

    • Definition: An apparatus used to study depth perception in infants. It tests whether infants can perceive depth through their actions.

  7. Gestalt Psychology

    • Figure and Ground Principle: Distinguishes between the object (figure) and its background (ground).

    • Principles of Grouping:

      • Proximity: Objects close to each other are grouped together.

      • Similarity: Similar objects are grouped together.

      • Closure: The mind fills in gaps to create a complete, whole object.

Module 19: Nonvisual Senses

  1. Hearing

    • Processes include: sound waves entering the ear, vibrating the tympanic membrane, which then moves the ossicles, leading to stimulation of the cochlea and hair cells.

    • The ear consists of three parts:

      • Outer Ear: Pinna and auditory canal.

      • Middle Ear: Ossicles (hammer, anvil, stirrup).

      • Inner Ear: Cochlea, semicircular canals.

    • Conductive vs. Sensorineural Hearing Loss:

      • Conductive loss occurs when sounds cannot efficiently travel through the outer and middle ear.

      • Sensorineural loss occurs due to damage to the inner ear or auditory nerve.

    • Hearing Aid vs. Cochlear Implant:

      • Hearing aids amplify sound, while cochlear implants convert sounds into electrical signals directly stimulating the auditory nerve.

  2. Four Skin Senses

    • Pressure

    • Temperature

    • Pain

    • Itch

  3. Phantom Limb Sensations

    • Definition: Sensations (including pain) perceived from an amputated limb.

  4. Smell

    • Relies on olfactory receptor cells to detect airborne molecules.

  5. Taste

    • Five Tastes:

    1. Sweet (indicates energy sources)

    2. Salty (indicates sodium essential for physiological processes)

    3. Sour (indicates acidity)

    4. Bitter (potential toxins)

    5. Umami (savory, indicates protein)

    • Refer to table 19.1 in the textbook for detailed classification.

  6. Kinesthesia Sense

    • Definition: The sense that provides information about the movement and position of the body parts.

  7. Vestibular Sense

    • Definition: Sense relating to balance and spatial orientation.

    • Receptors: Located in the semicircular canals and vestibular sacs of the inner ear.

    • Brain Connection: Nerve signals are sent to the cerebellum and other parts of the brain associated with balance and coordination.
