Asymmetry of the effective visual field in reading

In three experiments, subjects’ eye movements were recorded as they read from a computer-controlled CRT. The amount of information available to the left and right of the fixation point was varied in order to determine the characteristics of the effective visual field in reading. Experiments 1 and 2 demonstrated that readers do not obtain useful information during a fixation more than 3 or 4 letters to the left of their fixation point. The results of Experiment 3 indicated that the effective visual field does not extend any further to the left than the beginning of the word currently fixated, independent of the number of letters available to the left of fixation. When combined with the results of other research on the perceptual span in reading, the results of these experiments indicate that the effective visual field extends from the beginning of the currently fixated word (but no further than 4 characters to the left of fixation) up to about 15 characters to the right of fixation.

Prediction and judgment as indicators of sensitivity to covariation of continuous variables

The present study used both judgments of strength of relationship and measures of the ability to predict one variable from another to assess subjects’ sensitivity to the covariation of two continuous variables. In addition, one group of subjects judged strength of relationship after merely observing the presentation of 60 pairs of two-digit numbers, and a second group made strength judgments after being actively engaged in predicting one member of a pair when given the other. The prediction and judgment data provide different pictures of subjects’ sensitivity to covariation. The subjects were quite poor at estimating strength of relationship but, by some measures, good at predicting one variable from another. Judgments were not strongly influenced by whether subjects had previously engaged in overt prediction. The implications of these results for the literature on covariation estimation are discussed.     

An exploratory analysis of sex differences in gossip

This study examined sex differences in the quantity, targets, tone, and topics of gossip in the conversations of 76 male and 120 female college students. Contrary to popular beliefs, results indicated that the gossip of men and women contained similarities as well as differences. The data revealed that women spent more time gossiping than men and that women were much more likely than men to gossip about close friends and family members. However, no significant sex differences were uncovered regarding the derogatory tone of gossip and men and women were found to gossip about many of the same topics.We are grateful to Karl Seman, Marilla Ross, Robin Ansher, and Jack Schmaly, who served as observers during the data-collection phase of the study, and to Richard Weiner, who conducted the statistical analysis.
