Abstract

Humans stand out among animals for unique capacities in domains such as language, culture, and imitation, yet it has been difficult to identify cognitive elements that are specifically human. Most research has focused on how information is processed after it is acquired, e.g., in problem solving or “insight” tasks, but we may also look for species differences in the initial acquisition and coding of information.

In this seminar, I will present data and a new model showing that nonhuman animals are limited in terms of remembering arbitrary single events and lack a capacity for recognizing and remembering sequences of stimuli.

Collating data from 108 experiments on stimulus sequence discriminations (from 13 bird and mammal species), we have demonstrated pervasive and systematic errors, that persist after thousands of learning trials in tasks that humans learn to near perfection within tens of trials. In conclusion, animals represent sequences of stimuli as unstructured memory traces. Because human-level cognition requires more accurate encoding of sequential information than afforded by memory traces, this suggest that improved coding of sequential information can be a key cognitive element that may set humans apart from other animals.

Om Allmänna seminarieserien

Institutionens forskningsavdelningar samarbetar i Allmänna seminarieserien, där nationella och internationella forskare inbjuds att tala om aktuella forskningsämnen. Seminarierna äger rum onsdagar kl 14-15 i rum 357 om annat ej anges. Extraseminarier kan förekomma på andra dagar och tider, bl a halvtidsseminarier i forskarutbildningen.
