Summary
Some infants who bottom shuffle, a precursor to walking, may develop autism spectrum disorder (ASD). Early attention to social and cognitive development in these infants is crucial for timely diagnosis and intervention.
Area of Science:
- Developmental Pediatrics
- Neurodevelopmental Disorders
- Infant Locomotion
Background:
- Bottom shuffling is an infant locomotion method preceding independent walking.
- Shuffling infants typically exhibit favorable developmental outcomes.
- This study investigates the clinical and neurodevelopmental profiles of shuffling infants.
Purpose of the Study:
- To identify clinical features of infants who bottom shuffle.
- To determine neurodevelopmental outcomes in shuffling infants.
- To explore the association between bottom shuffling and autism spectrum disorder (ASD).
Main Methods:
- Retrospective chart review of 48 shuffling infants at a child development center (2007-2015).
- Exclusion of infants with cerebral palsy, Down syndrome, or congenital disorders.
- Analysis of family history, neurological findings, and developmental outcomes, including ASD diagnosis.
Main Results:
- 42% of shuffling infants were diagnosed with ASD during follow-up.
- No significant differences in gross motor development were observed between infants with and without ASD.
- Infants with ASD showed higher rates of poor eye contact and delayed first word speech.
- Family history of bottom shuffling was less common in infants later diagnosed with ASD.
Conclusions:
- A subset of infants who bottom shuffle may later be diagnosed with ASD.
- Early identification of social and cognitive delays is vital for shuffling infants.
- This highlights the importance of monitoring neurodevelopmental trajectories in shuffling populations.

01:19Autism Spectrum Disorder
765
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:26Modeling in Therapy
288
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

01:29Biological Causes of Schizophrenia
354
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.

01:28Social Anxiety Disorder
276
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

01:29Psychological and Sociocultural Causes of Schizophrenia
357
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...

Attachment is a long-standing connection or bond with others. While Attachment Theory was conceived in developmental psychology to describe infant-caregiver bonding, it's been extended into adulthood to include romantic relationships.
