when testing for categorization in pigeons, herrnstein (1979) taught pigeons to categorize trees by discriminating trees from non-trees. which is a correct finding from this study?



Answer :

The correct findings from the study is c. Pigeons learned to successfully discriminate pictures of trees from pictures without trees, and also successfully generalized this skill to novel/new tree pictures.

Visual Stimuli of Pigeon:

There are parallels between how pigeons and people categorize visual stimuli in terms of colour photos. Pigeons can learn to distinguish between images based on whether there are people, trees, or bodies of water in them (Herrnstein, Loveland, & Cable, 1976). Pigeons can also categorise photos using the idea categories of cats, flowers, vehicles, and chairs, as demonstrated by Wasserman, Kiedinger, and Bhatt (1988, Experiment 2). Two teams of pigeons classified 80 slides in their experiment.

While those in the pseudocategory group were rewarded for classifying the stimuli based on four arbitrary categories, each of which contained an equal number of stimuli from the four concept categories, those in the category group were rewarded for classifying the stimuli according to their concept categories.
