“…More recently, however, other researchers have concluded that graphs should be used primarily when people have to use their judgement to analyse trends and make forecasts (Coll et al, 1991;Tullis, 1988); in fact, Dickson et al (1986) argue that there is no point in producing them for any other purpose. Our findings are consonant with this view: using the task information did not require judgement of trends and overall performance level did not differ between display formats.…”

Medical students estimated probabilities that medical school applicants selected randomly from a defined population would be offered a place on the basis of information about eight characteristics of each one. Estimates were biased in favour of acceptance and this was unaffected by mere provision of base rate information. However, a first experiment showed that provision of this information reduced miscalibration after each candidate had been discussed within small groups of participants. A second experiment showed beneficial effects of providing people with the range of probability responses derived from a statistical model of how candidates' characteristics influenced whether or not they were offered a place. Numerical and graphical representations of this information both improved calibration but did so by having different effects on the distribution of participants' probability responses.

“…There is some consensus that graphical presentation produces better performance than tabular presentation when people are required to use their judgment to analyze trends and to make forecasts (Coll, Thyagarajan & Chopra, ; Dickson, DeSanctis & McBride, ; Tullis, ). Harvey and Bolger () confirmed that graphical presentation is superior for this purpose when data contain trends and showed that this was because trend damping was much greater with tabular presentation.…”

People made forecasts from real data series. The points in the series were un‐trended and independent. Hence, forecasts should have been on the mean value. However, consistent with previous research on forecasting biases, forecasts were too close to the last data point. It appears that forecasters see positive sequential dependence where none exists. In three experiments, we examined this bias in different types of forecasting task: point forecasting, probability density forecasting, and interval forecasting. In all cases, we found that it was greater when the data series were displayed using continuous line graphs than when it was displayed using discrete point graphs. Consistent with arguments made by Zacks and Tversky (Memory and Cognition, 27:1073, 1999), we suggest that people are more likely to group data together and to see patterns in them when those data are presented in a continuous than in a discrete format. These findings have implications for forecasting practice.

“…This general principle of organization for cognitive compatibility is an aspect of Cognitive Match Interface Design (COMIND) promulgated by Co11 et al in several previous papers (Co11 & Coll, 1989;Coll, Thyagarajan, & Chopra, 1991;Co11 & Wingertsman, 1990). The COMIND message is that a computer system must be designed so that it operates in a manner which parallels the human thought process, so that it, in effect, anticipates the needs and actions of the user.…”

In a two‐experiment sequence, we examine task time across several orderings of menu lists. Findings demonstrate that it is not sufficient to consider good physical layout in screen design (as some researchers suggest), and that good physical layout is subordinate to good conceptual layout. A second purpose of these two experiments is to extend previous work to encompass smaller menus of item size nine and fewer, an important area, since guidelines recommend menus with nine or fewer items for maximizing the effectiveness of the user interface. © 1993 John Wiley & Sons, Inc.
