If vision can be considered the basis of geographic inquiry, then it must involve looking with discrimination--the ability to discern clues in our surroundings that speak to spatial processes or patterns in all aspects of geography--physical, cultural, economic, and so on. Geographic thinking also involves making spatial generalizations. We do…

Although it is acknowledged that adults integrate features into a representation of the whole face, there is still some disagreement about the onset and developmental course of holistic face processing. We tested adults and children from 4 to 6 years of age with the same paradigm measuring holistic face processing through an adaptation of the…

We calculated visual ability in 13 strains of mice (129SI/Sv1mJ, A/J, AKR/J, BALB/cByJ, C3H/HeJ, C57BL/6J, CAST/EiJ, DBA/2J, FVB/NJ, MOLF/EiJ, SJL/J, SM/J, and SPRET/EiJ) on visual detection, pattern discrimination, and visual acuity and tested these and other mice of the same strains in a behavioral test battery that evaluated visuo-spatial…

The present article discusses the possibility that behavioral recovery following brain damage is not dependent on the functional reorganization of neural tissue but is rather the result of the continued normal operation of spared neural mechanisms. (Editor)

Conducted two experiments which employed discrimination learning methods to test predictions related to the difficulty of discrimination of lateral reversals and of inversions when shapes are presented: (1) successively, (2) simultaneously in lateral alignment, and (3) simultaneously in vertical alignment. Subjects were 6-year-old children. (SDH)

An examination of the extent to which adults and children (7 and 11 years old) were able to make discriminations between fixations directed at their eyes and at different positions on their faces. (SDH)

This article describes a study to determine the effect of presentation mode and letter similarity on visual discrimination learning and to determine what effect the differential initial learning conditions have on subsequent paired associate learning. (PD)

Infants' visual perception of number change was investigated in three studies. These studies focused on infants' perception of events in which the total number of objects in a small group was changed through addition of another object. Involving 60 infants 5 months of age, Study I attempted to determine whether subjects perceived the properties in…

Butler (1980) compared errors representing intrusions and mislocalizations on 3x3 letter displays under pattern-mask versus no-mask conditions and found that pattern masking increased character mislocalization errors (naming a character in the display but not in the target position as being the target) over intrusion errors (naming a character not…

The paper reviews issues in evaluating the manual communications skills of pre-college hearing impaired students, including testing of visual discrimination and visual memory, simultaneous communication, and attention span. (CL)

TEN PAIRS OF BLIND CHILDREN AGED SIX TO 13 YEARS WHO HAD SOME VISION WERE MATCHED BY PRETEST SCORES ON A TEST OF VISUAL DISCRIMINATION. A CRITERION GROUP, DESIGNATED THE PRINT COMPARISON GROUP, HAD SLIGHLY HIGHER RECORDED DISTANCE ACUITIES AND USED VISION AS THE PRIMARY MEANS OF LEARNING. PAIRS OF EXPERIMENTAL SUBJECTS DAILY RECEIVED 45 MINUTES OF…

A STUDY WAS CONDUCTED TO DETERMINE WHETHER PEOPLE CAN CHANGE THEIR PERCEPTUAL PROCESSING STRATEGIES TO INCLUDE TESTS FOR THE PRESENCE OF ONLY THOSE STIMULUS FEATURES NECESSARY FOR THE TASK AT HAND. LEARNING DURING PRACTICE AND THE EFFECT OF AGE ON THE ABILITY TO USE OPTIMAL STRATEGIES WERE INVESTIGATED. A DISJUNCTIVE REACTION TIME PROCEDURE WAS…

THE EFFECTIVENESS OF TWO TRAINING METHODS TO FOCUS ATTENTION ON THE CRITICAL FEATURES OF LETTER-LIKE FORMS WAS STUDIED. SUBJECTS WERE 32 KINDERGARTEN PUPILS. SIX NONSYMETRICAL, STANDARD LETTER-LIKE FORMS AND FOUR TRANSFORMATIONS, CONSISTING OF RIGHT-LEFT AND UP-DOWN REVERSALS, 180 DEGREES AND 90 DEGREES ROTATION, WERE USED AS STIMULI TO LEARNING.…
