Before “Inside Out,” there was another animated film that explored emotions and psychological and cognitive development. Based on the pioneering work of psychoanalyst Erik Erikson, animators John and Faith Hubley created “Everybody Rides the Carousel,” with segments illustrating Erikson’s stages of the human lifetime, each presenting a choice between confidence, independence, creativity, intimacy, learning — or weakness, fear, and isolation.

This is a more abstract, demanding film than “Inside Out,” but for those who want to continue to explore ideas about the way our emotions and memories guide our lives, this is well worth a look. Listen for Meryl Streep’s voice, early in her career, in this clip.
