Some abnormal behaviours may be related to environmental conditions (e.g. captive housing) whereas others may be due to medical conditions. The list does not include behaviours in animals that are genetically modified to express abnormal behaviour (e.g. reeler mice). A polar bear performing stereotyped pacing.
Stranding in these circumstances is a behavior in which a whale temporarily beaches itself to reach prey on land near to the shoreline. Adult whales have been observed helping juveniles with many aspects of this behavior by pushing them up and down the beach, guiding them towards prey, and intervening when the juveniles find themselves in danger.
The novel object recognition (NOR) test is an animal behavior test that is primarily used to assess memory alterations in rodents. It is a simple behavioral test that is based on a rodents innate exploratory behavior. The test is divided into three phases: habituation, training/adaptation and test phase.
Rating traits involve a group of observers that scrutinize the behavioural traits of an individual animal. Observers are typically given a list of characters and/or descriptions to use as a reference for interpreting animal behaviour then use the list to rate the behaviours. [11] The rating method uses observers and data recording instruments. [1]
Skinner's studies on animals and their behavior laid the framework needed for similar studies on human subjects. Based on his work, developmental psychologists were able to study the effect of positive and negative reinforcement. Skinner found that the environment influenced behavior and when that environment is manipulated, behaviour will change.
Deception in animals is the voluntary or involuntary transmission of misinformation by one animal to another, of the same or different species, in a way that misleads the other animal. Robert Mitchell identifies four levels of deception in animals.
Ethograms are used extensively in the study of welfare science. Ethograms can be used to detect the occurrence or prevalence of abnormal behaviours (e.g. stereotypies, [5] [6] feather pecking, [7] tail-biting [8]), normal behaviours (e.g. comfort behaviours), departures from the ethogram of ancestral species [9] and the behaviour of captive animals upon release into a natural environment.
