Experiments in Human Memory
Programs and Pictures
Joan Gay Snodgrass & Jin Fan
Since 1980 a set of pictures, designed and
standardized by Professor Joan G. Snodgrass of
These images are available from LSA in film, print or electronic form or as rights to reproduce the images in your instrument, screen or test. There is also a suite consisting of a) the pictures themselves, b) fragmented pictures at eight levels, c) programs for presenting the pictures and recording and analyzing data obtained from the presentations. These materials are suitable for memory research and clinical screens, instruction, laboratory exercises and classroom demonstrations.
- 260 STANDARDIZED PICTURES. This set contains the standardized pictures and their norms. For IBM they are .tif files which can be shown within popular word processor programs such as Word, or with an included graphics program. For Macintosh the pictures are presented in a hypercard stack. For the PC individual pictures are available at $1.50 ea. with a minimum order of 75 slides, prints or files or for a license to reproduce the images( $1.50 for each reproduction with a minimum of 75).
- NEW! High Resolution. For IBM, the pictures are offered on a CD in 3 folders each containing the 260 picures in jpg, tif and pct formats. The pct pictures are very high resolution – about 7000 x 8000 dpi.
- Email LSA for a sample of
each format.
Cat. # 4210-I (for IBM-Windows) or #4210-M (for Macintosh) $195.00 plus $7.95 S&H. - INSTRUCTIONAL GUIDE
for use of Standardized Pictures for Experiments
in Human Memory. This guide describes in detail the experiments and
procedures used in the contemporary study of human memory, with
illustrations of the use of standardized pictures as stimuli.
Cat. #4211-G $15.00 plus $7.95 S&H.
- EXPERIMENTS IN MEMORY FOR
PICTURES AND WORDS. The ten different kinds of memory
experiments covered in the manual above are programmed for convenient
administration by computer. They include both recall and recognition tests
as well as tests of temporal and spatial order and use and include the 260
standardized pictures. A virtual library of paradigms, this set permits
simple and sophisticated experimentation in human memory.
Cat. #4213-I (for IBM-Windows) or #4213-M (for Macintosh), $295.00 plus $7.95 S&H.
- FRAGPIX EXPERIMENTS.
This consists of a set of five programs using fragmented ( at 8 levels) pictures for such memory research as
testing priming in implicit memory. The programs present a study set of 15
fragmented pictures and then a test set of 30 pictures (half old and half
new). The programs differ in whether the study presentation is of a single
level of fragmented image or the ascending method of limits and whether
the response is typing the picture's name or clicking Yes/No buttons. The
software includes five sets of 30 pictures so that repeated testing can be
done. [For a reference, see Snodgrass, J. G., Smith, B., Feenan, K., & Corwin, J. (1987). Fragmenting
pictures on the Apple Macintosh computer for experimental and clinical
applications. Behavior Research Methods, Instruments, & Computers , 19, 270-274.]

- ULTRAFRAG -Program to
fragment any set of stimuli. This program permits an investigator to
fragment any set of stimuli or pictures using the method described in
Snodgrass et al. (1987) in which blocks of pixels are randomly deleted
from the image.

- Hard copy formats as well as 2"x2" slides are also available. Please inquire. LSA also publishes software in Experimental Psychology, Perception and Cognitive Rehabilitation including driving assessment. Let us know if you wish information.
