The effects of viewing different types of information were investigated in people judging the social acceptability of alternative forest harvest systems. Approximately 500 Tasmanians were shown still-simulated images of four harvest systems (a clearfell system, two aggregated retention systems, and a selective system) and were asked to judge their acceptability. Individual interviews were conducted with 12 of the participants. It was anticipated that people holding different beliefs about the consequences of harvesting would have different responses to information. Cluster analysis was used to group participants according to these beliefs. Responses to still images were compared with responses to two other types of information: information about consequences of the harvest systems in the form of indicator symbols, and information about regeneration over time, presented as visual animations. The effects of information differed across both harvest system and belief cluster groups of participants. The largest effects of information occurred in people who held a mix of beliefs about consequences. Within this group, participants who viewed the indicators rated a 30% aggregated retention system higher and selective harvesting lower, than those who did not view the indicators. Viewing animated sequences led to slightly higher ratings of the more intensive harvest systems and significantly lower ratings of the selective harvest system than those based on the still images. The interview data provided examples of interviewees viewing information critically against their own values and beliefs. Only some interviewees appeared to use it in judging social acceptability.
本研究旨在调查人们在评判替代森林采伐系统的社会可接受性时，观看不同类型信息的效果。约 500 名塔斯马尼亚人观看了四种采伐系统（皆伐系统、两种集材保留系统和择伐系统）的静态模拟图像，并被要求评判其可接受性。对其中 12 名参与者进行了个体访谈。人们预期，对采伐后果持有不同信念的人对信息会有不同的反应。聚类分析用于根据这些信念对参与者进行分组。将静态图像的反应与其他两种信息类型的反应进行比较：以指标符号形式呈现的采伐系统后果信息，以及以视觉动画形式呈现的随时间推移的再生信息。信息的效果在采伐系统和信念聚类组的参与者中均有所不同。信息的最大影响出现在对后果持混合信念的人群中。在这群人中，观看指标的参与者对 30%的集材保留系统的评价高于未观看指标的参与者，对择伐的评价则低于未观看指标的参与者。观看动画序列导致对更密集的采伐系统的评价略高，对择伐系统的评价明显低于基于静态图像的评价。访谈数据提供了一些受访者根据自己的价值观和信念批判性地看待信息的例子。只有一些受访者似乎在评判社会可接受性时使用了这些信息。
