Document Summary

Webers law= difference threshold, dl/s=k stevens power law, magnitude estimation, p=ksto the power of n response compression: stimulus intensity is higher than percieved (exponent less than 1) response expansion: stimulus intensity is lower than percieved (exponent higher than 1) Visual search: find one stimulus amoung many as fast as possible. Info can be passed within or between neurons. If passed within, the exchange is all electrical (change in potentials) Electricity in the brain: energy resulting from charged particles, (neg moving towards positive, vise versa) Charged molecules called ions (positive is cations and negative is anions) Two types that play important role of electrical ions within axon: sodium ions (na+), and potassium (more inside, k+) Organic anions (protiens) that have negative charges and are found inside the cell, they cause the stron negative charge to create a negative potential within the cell.
