The conclusion drawn by Donald Griffin from his observations of heron’s fishing patterns may not provide an adequate explanation for the cognitive processes that occur with the patterns. One problem with drawing this conclusion is that he is observing the behavior of heron’s in their natural environment. When it comes to natural observation, causation and conclusions about behavior cannot be drawn. Griffin’s conclusion cannot be supported because it is anecdotal evidence that may hold personal biases. When anecdotal evidence is presented, it is difficult to distinguish between what was seen and what was inferred by the observer. Griffin’s point of view also holds an anthropomorphic stance because he is looking at the heron’s behavior from a human perspective. The heron’s fishing behavior may be the result of associative learning. It is natural sensation that a heron needs to catch fish for food. Through the process of trial and error, the heron may have learned to pair dropping a pebble in the water with retrieving food.

There are four different tasks that can be used to study visual perception including visual search task, forced-choice task, go/no-go task, and stimulus discrimination task. The visual search task involves scanning an image to find a specific target. The forced-choice task presents subjects with a pattern of choices in which they are forced to choose which choice they believe is the target stimulus. In the go/no-go task, participants will view a stimulus and respond with the appropriate action given to them by researchers. After responding with the desired action, a different stimulus will be presented, and subjects are asked to not perform the previous response. In the stimulus discrimination task, different stimuli are presented to the subject and they must differentiate between the target stimulus and the
