Binocular Rivalry

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Why do people have two forward-facing eyes? By presenting the brain with two ever so slightly different images it becomes possible to comprehend visual problems that are far more difficult to process through a single eye. Chief among these is the problem of 3-D perception, seeing the world in three dimensions, despite retinal inputs in only two dimensions. What happens if each eye receives two completely different images? That...

Binocular rivalry occurs when the eyes are presented with different images at the same location: one image dominates while the other is suppressed, and dominance alternates periodically. Rivalry is useful for investigating perceptual selection and visual awareness. Here we describe several easy methods for creating and using binocular rivalry stimuli.

Relationship with Other Adult Family Members and Siblings

Other adult family members and siblings play a crucial role in shaping children’s social and emotional development. While parents or primary caregivers are often the central figures in early attachment and socialization, other adults in a child’s life, such as grandparents, aunts, and uncles, can significantly influence developmental outcomes. These influences depend on each adult’s personality and may help compensate when a primary caregiver is emotionally distant or inconsistent. For...

Infants often form early attachments to older siblings, using them as a source of comfort during distress. As infants become more mobile, sibling conflict commonly increases over toys, personal space, and parental attention, particularly after about 18 months.Conflict and Social LearningAs toddlers become more involved in family interactions, they learn which behaviors please or annoy their siblings. Although disagreements may involve rivalry or frustration, they can also promote...

Microinjection of Interleukin-6 into the Bloodstream of TSC Zebrafish Larvae to Study Neuropsychiatric Disorder-Like Behaviors

To model how inflammatory signals influence neurodevelopment in genetically susceptible organisms, we present a protocol for microinjecting IL-6 into the duct of Cuvier (common cardinal vein) of zebrafish larvae, enabling controlled induction of inflammation and assessment of its developmental impact in the context of tuberous sclerosis complex (TSC).
FAQs
Competition can intensify when children compare the attention, recognition, resources, roles, or privileges they receive with those given to a sibling. Perceived differences in parental treatment may make one child feel overlooked or another feel pressured to maintain an advantage. These comparisons help explain why ordinary disagreements can become recurring patterns of jealousy, conflict, or competition within the family.
Children may interpret unequal treatment as evidence that a sibling is more valued, trusted, or favored, even when parents do not intend that message. Such perceptions can increase resentment and encourage further competition for recognition or privileges. Examining how children understand family treatment, rather than only the treatment itself, helps psychologists analyze the emotional processes sustaining rivalry.
Siblings may compete not only for parental attention but also for a separate role or identity within the family. When children seek recognition as different from one another, disagreements can become connected to status, expectations, or family roles. This process can produce tension, yet it also shows how sibling relationships develop alongside changing ideas about individuality and belonging.
Manageable disagreements can give children opportunities to practice negotiation, emotional regulation, and perspective-taking. These experiences may help them consider another person's viewpoint while working through competing needs or claims. The developmental value depends on the conflict remaining manageable; persistent or intense rivalry is more concerning because it may contribute to ongoing stress and conflict within the family.
Assessment should focus on the pattern and intensity of conflict, the children’s perceptions of parental treatment, and the roles played by attention, recognition, resources, and privileges. Psychologists can also consider whether disagreements remain manageable or contribute to stress. This broader view connects individual reactions with family dynamics instead of treating each argument as an isolated event.
Studying these interactions can guide strategies that emphasize fair communication, conflict resolution, and healthier sibling relationships. Attention to perceived favoritism, competition for roles, and changing family relationships may help families address the conditions driving disputes rather than only the visible argument. In clinical or research contexts, this perspective supports a more systematic understanding of family dynamics and relationship outcomes.
