  1. Question: associative learning • Complete the following description of Hebbian synaptic plasticity:Neurons that _________ together, _______together. ANSWER: fire, wire Exam III practice questions

  2. Question: motion detection • The motion detection circuit shown to the right will respond maximally to a target of the appropriate velocity movinga) from LEFT-to-RIGHTb) from RIGHT-to-LEFT temporal summation ‘AND’ gate ANSWER: from LEFT-to-RIGHT; the pathway with the delay element must be excited first. Exam III practice questions

  3. Question: honeybee foraging • Approximately what fraction of a worker bee’s life is spent as a forager? ANSWER: about 50%; (lifespan is about 1 month, foraging during last 2 weeks) Exam III practice questions

  4. Question: honeybee associative learning • For effective learning in the honeybee proboscis extension reflex paradigm, the ____ should precede the ____ by about 3 seconds.a) US, URb) CS, CRc) CS, USd) CR, UR ANSWER: (c); the conditioned stimulus (odor) should precede the unconditioned stimulus (sucrose) by about 3 seconds. Exam III practice questions

  5. Question: honeybee associative learning • In the Montague et al. model of bee foraging, the probability for selecting a blue flower P[b] is given by: P[b] = 1/(1 + exp(-b(xb-xy)))What is the probability for selecting a yellow flower?a) P[y] = 1/(1 + P[b])b) P[y] = 1 - P[b]c) P[y] = 1/(1 + exp(-b(xb+xy)))d) P[y] = P[b]/(1+P[b]) ANSWER: (b) Exam III practice questions

  6. Question: ant foraging • If no new pheromone is deposited along an ant trail, how quickly does it evaporate (half-life) ?a) about 0.5-1.0 secondsb) about 0.5-1.0 minutesc) about 0.5-1.0 hoursd) about 0.5-1.0 days ANSWER: (c) Exam III practice questions

  7. Question: memory systems • Which of the following types of memory would be considered ‘dispositional’ rather than ‘representational’ (circle all that apply) ?a) episodicb) explicitc) procedurald) semantic ANSWER: (c) Exam III practice questions

  8. Question: active sensing systems • Place the following active sensing systems in order based on the spatial extent of their probe emission, from narrowest to widest: bats, dolphins, electric fish. _____________________________________ ANSWER: dolphins, bats, electric fish Exam III practice questions
