A Study Of Figural After-Effects In The Inverted-“T”-Illusion, Wayne H. Bartz

Masters Theses

Introduction

The term figural after-effect refers to the spatial displacement of a visual figure induced by the inspection of a prior figure. In the figural after-effect paradigm, an observer fixates on a figure called the inspection figure for some time. Fixation is then shifted to a test figure. Any spatial displacement in the test (second) figure is termed the figural after-effect. Generally, maximal figural after-effects are attained with 60 second inspection followed immediately by short test figure exposure (Hammer, 1949; Graham, 1951; Krauskopf, 1954; Parducci and Brookshire, 1956; Sagara and Oyama, 1957; and Kohler and Wallach, 1944). This study is …

Masters Theses

Chapter I

Introduction

The problem of alcoholism is one of the oldest problems in the history of mankind. Today it ranks world-wide as a major public health problem. Yet, constructive study and research on the subject did not gain much momentum until about 1935.

An Investigation Of The Horizontal-Vertical Illusion, Frederick J. Boersma

Masters Theses

Experimenters have used the inverted "T" to illustrate the horizontal-vertical illusion for many years. This illusion is characterized by the subject perceiving the horizontal line as shorter than the vertical line.

Credit is usually given to Fick (1851) for being first to call attention to the discrepancy between horizontal and vertical estimates. He demonstrated this by visually noticing that a bright square on a dark background looks like an oblong object. Hicks (1906) stated that Oppel was the first person to actually investigate the horizontal-vertical illusion.

The classical theory generally states that an equal length vertical line in a "T" …
