Two studies were conducted to determine the impact of infants' attachment classifications and behaviors on naive adults' impressions of their behavior and mental health. In Study 1, three groups of 44 adults viewed a videotape of episode 8 of the Strange Situation for either an avoidant, a resistant, or a secure male infant. After viewing the videotape, they made judgments about aspects of the infant's mental health. Adults viewed the resistant baby as less socially competent and more negative in affect than the other two babies and the secure baby as the least independent of the three babies. Parents rated babies as more intelligent than did nonparents. In Study 2, 15 parents were matched on race and gender with 15 nonparents. All adults viewed a videotape of the reunions of two secure, two avoidant, and two resistant male infants. Avoidant babies were viewed as more socially competent and independent than secure babies and the C2 baby was viewed as the least intelligent, least independent, least socially competent, and most affectively negative of the infants. Results are interpreted as underscoring the need to educate parents and paraprofessionals about the importance of infant distress and physical contact with parents.
