Cognitive Maps in Rats and Men Edward Chance Tolman made many significant findings to the studies of learning, memory and motivation. Today Tolman would be considered a Cognitive Behaviorist, he developed his own brand of behaviorism which emphasized the purposeful nature behind an organism's actions, taking into account it's goals and motivations. “He is best remembered for being a pioneer in cognitive psychology during a time when behaviorists dominated the field. Tolman made several significant…

Rats are various medium sized rodents. "True rats" are members of the genus Rattus, the most important of which to humans are the black rat, Rattus rattus, and the brown rat, R. norvegicus. Many members of other rodent genera and families are also called rats and share many characteristics with true rats. A rat has an average life span of 2-3 years[1]. Rats are distinguished from mice by their size; rats generally have bodies longer than 12 cm (5 in). Contents [hide] * 1 Species and description…

The present study found supporting evidence for incubation effects, where participants in the incubation condition scored higher averages on the RAT. This finding supports the first hypothesis that incubation will improve problem solving performance on the RAT. This study has demonstrated and confirmed results from previously mentioned studies on the positive effects of incubation on problem solving (eg., Smith & Blankenship, 1991; Segal, 2004; Baird et al., 2012; Sio & Ormerod, 2009). However, no…

obtained from Provet (Auckland, NZ). Ethanol was obtained from PureScience (Wellington, NZ). Cocaine-HCl (BDG Synthesis, Wellington, NZ) was dissolved in physiological saline (0.9%) containing heparin sodium (3 U/mL) and made up to a solution of 1.65 g/L (rats were considered to average 330 g). Each intravenous infusion was 0.1 mL and delivered over a period of 12 s (0.5 mg/kg/infusion). For intraperitoneal injections, cocaine-HCl was dissolved in physiological saline to a concentration of 2 mg/mL. Surgery…

Results: For the experiment we observed a total of 8 trials. Each trial consisted of two rats. The rats were 25-day-old Long-Evans hooded rats. Each rat was randomly assigned to one of two drug groups. The groups were either administered 1.0 mg/kg of Naloxone or an injection of saline. Among the 8 trials, 4 of the trials the rats were given Saline, and among the other 4 trials the rats were given Naloxone A pin response can be described as when one of the animals lies on its back , with its spinal…
