PSYCH 1 Lecture Notes - Lecture 6: Cranial Nerves, Phototropism, Phototaxis
Document Summary
Patellar (knee), eye blink, sneeze, and cough reflexes: mediated by the spinal or cranial nerves no higher thinking involved. Fairly basic: can be linked to survival, but are not learned", didn"t have to learn to blink, taxis, more rare, but can be initiated by a myriad of different stimuli across different species. Phonotaxis response to sound stimuli: startle/ avoidance (jump) from loud sounds. Set responses that do not vary in repertoire: they are very species specific!! All things done by a single species. Imprinting in greylag geese (konrad lorenz: herding instincts of specific dog species. Egg laying of sea turtles: linked to critical periods, appreciating the critical periods. Imprinting, aggressive tendencies: happen in moments that are really important in life, may mess with the situation. Light pollution and environmental changes have messed with the prevalence of these stimuli and upset the order of actions that the sea turtles have relied on for centuries in order to survive.
