SCiP at 35: An idiosyncratic history of the Society for Computers in Psychology

SCiP history may be divided into three eras: the Paleozoic (1971–1982), the Mesozoic (1982–1994), and the Cenozoic (1994-present). Following a list of Secretary-Treasurers, a list of all SCiP Presidents is provided in Table 1. Next I present personal highlights, including the first symposium on psychology and the World-Wide Web; David Rumelhart’s mathematical explanation of connectionism; and Stevan Harnad’s discussion of “freeing” the journal literature. I observe that a small conference is becoming more intimate and that much of our mission involves figuring out how to conduct high-quality scientific research with consumer-grade electronics. I argue that we are an increasingly international organization, that graduate students are welcome, and that we should become more inclusive in the areas of gender and ethnicity and should make membership more meaningful. I conclude by looking ahead and attempting to predict the future.     

Twenty years of Internet-based research at SCiP: A discussion of surviving concepts and new methodologies

This discussion of the symposium 20 Years of Internet-Based Research at SCiP: Surviving Concepts, New Methodologies compares the issues faced by the pioneering Internet-based psychology researchers who presented at the first symposia on the topic, at the 1996 annual meeting of the Society for Computers in Psychology, to the issues facing researchers today. New methodologies unavailable in the early days of Web-based psychological research are discussed, with an emphasis on mobile computing with smartphones that is capitalizing on capabilities such as touch screens and gyro sensors. A persistent issue spanning the decades has been the challenge of conducting scientific research with consumer-grade electronics. In the 1996 symposia on Internet-based research, four advantages were identified: easy access to a geographically unlimited subject population, including subjects from very specific and previously inaccessible target populations; bringing the experiment to the subject; high statistical power through large sample size; and reduced cost. In retrospect, it appears that Internet-based research has largely lived up to this early promise—with the possible exception of sample size, since the public demand for controlled psychology experiments has not always been greater than the supply offered by researchers. There are many reasons for optimism about the future of Internet-based research. However, unless courses and textbooks on psychological research methods begin to give Web-based research the attention it deserves, the future of Internet-based psychological research will remain in doubt.     

Group discussion as interactive dialogue or as serial monologue: the influence of group size

Current models draw a broad distinction between communication as dialogue and communication as monologue. The two kinds of models have different implications for who influences whom in a group discussion. If the discussion is like interactive dialogue, group members should be influenced most by those with whom they interact in the discussion; if it is like serial monologue, they should be influenced most by the dominant speaker. The experiments reported here show that in small, 5-person groups, the communication is like dialogue and members are influenced most by those with whom they interact in the discussion. However, in large, 10-person groups, the communication is like monologue and members are influenced most by the dominant speaker. The difference in mode of communication is explained in terms of how speakers in the two sizes of groups design their utterances for different audiences.     

The Collective Preference for Shared Information

Decision-making groups prefer to discuss shared information that all members know instead of unshared information that a single member knows. This bias toward discussing shared information can lead groups to make suboptimal decisions when unshared information is critical for good decision making. This preference for discussing shared information may stem from group members' positive evaluations of each other's task capabilities when shared information is communicated. Members who already are perceived as capable (i.e., those high in status, experts, and leaders) need not bolster their image by communicating shared information. Instead, they discuss unshared information more than members perceived as less capable. As members low in status gain respect by communicating shared information, they may risk mentioning unshared information later during discussion. Assigning group leaders, informing members of their expert roles, and allowing ample time for discussion may increase groups' discussion of unshared information.     

The communication of social stereotypes: the effects of group discussion and information distribution on stereotypic appraisals

Stereotypes are fundamentally social constructs, formulated and modified through discussion and interaction with others. The present studies examined the impact of group discussion on stereotypes. In both studies, groups of participants discussed their impressions about a hypothetical target group after having read behaviors performed by target group members. These behaviors included both stereotypic and counterstereotypic examples, and the distribution of these behaviors varied across discussion group members. In some groups only 1 member knew of the counterstereotypic behaviors; in other groups this information was distributed across all group members. In general, discussion led to a polarization of the target group stereotypes, but this effect was lessened when the counterstereotypic behaviors were concentrated in 1 group member. In this case, these counterstereotypic behaviors were discussed more and retained better.     

多决策方法多交流方式的群体决策比较

采用人员选拔的实验室模拟实验,以160名被试组成40个4人群体,对4种决策方法和2类交流方式的群体决策进行了比较。结果发现（1）决策方法和交流方式对于讨论过程的信息交流具有显著影响;（2）以计算机为中介进行决策的被试知觉到的任务难度要高于面对面决策条件;决策方法对于群体成员有关实验任务难度知觉具有主效应;交流方式和决策方法对于群体决策过程满意感和结果满意感没有显著影响;（3）在以投票轮次来表明群体达成一致意见所需时间上,决策方法对于投票轮次具有显著影响。恶魔式辩护、辨证式查询两种方法下所需的投票轮次多于专家意见法和自由讨论法的投票轮次。     

群体决策过程中的信息取样偏差

一般认为,决策群体的优势是能综合各个成员拥有的不完整信息,形成对所有决策备择方案的无偏差的认识,从而作出最佳选择。但“群体讨论中的有偏差信息取样模型’认为,群体在决策中往往表现出倾向于讨论两种信息：(1)各成员讨论前都拥有的信息;(2)支持成员在讨论前所偏好的信息。该实验通过模拟人员选拔决策形式的实验室实验,对这一模型的假设进行验证。研究结果表明,大多数群体选择了一开始受到大多数成员支持的候选人,而非实际的最佳人选;群体讨论非但未纠正,反而加强了成员对候选人原有的歪曲印象。     

The impact of information distribution,ownership, and discussion on group member judgment: The differential cue weighting model

It is often assumed that groups or teams pool knowledge and consider more information than individuals. However, numerous group decision-making studies have found that groups tend to focus on information that members had in common before group discussion instead of exchanging members’ unique information. This paper extends previous research and introduces the differential cue weighting (DCW) model to explain how group members form and revise their judgments during group discussion. It is proposed that information cues are differentially weighted depending on the combination of three factors: the cue’s initial distribution, its ownership by the member, and its addition to group discussion. An empirical study provides support for the DCW model, demonstrating that, for individual judgment, unique information can be just as influential as common information, but only for the member who contributed it to discussion.     

Managing anger for teamwork in Hong Kong: goal interdependence and open–mindedness

Anger is part of working in a team, as is dealing with its frustrations and conflicts. The cooperative–competitive approach to conflict suggests that how open–mindedly the anger incident is discussed impacts on its dynamics and outcomes. Results from critical incident interviews of organization members in Hong Kong clarify how team members can manage their anger. Structural equation and other analyses suggest that open–minded discussion of the anger–inducing incident promotes productivity and strengthens relationships; thereby developing commitment and a belief that team members are resourceful. These constructive dynamics and outcomes were found to occur when team members had co–operative but not competitive nor independent goals. Results were interpreted as suggesting that even in a society where collectivist and conflict–negative values are influential, anger can be managed constructively through an open–minded discussion of the incident.     

Consistency of Response to Personality Inventory Items as a Function of Length of Interval Between Test and Retest

Summary

Four member discussion groups (N = 80 male and female college students) were set up in which two members favored each side of the issue. In half the groups, the involvement of the members in the issue under discussion was relatively high; in the other half it was relatively low. While the potential for intragroup tension was greater in the high involvement group, this threat was successfully dealt with by a significantly larger number of tension reducing statements and statements deflecting hostility towards objects outside the group. These defensive maneuvers were particularly marked for one of the two discussion topics which appeared to be intrinsically more involving.     

An impoverished machine: Challenges to human learning and instructional technology

Many of the limitations to human learning and processing identified by cognitive psychologists over the last 50 years still hold true, including computational constraints, low learning rates, and unreliable processing. Instructional technology can be used in classrooms and in other learning contexts to address these limitations to learning. However, creating technological innovations is not enough. As part of psychological science, the development and assessment of instructional systems should be guided by theories and practices within the discipline. The technology we develop should become an object of research like other phenomena that are studied. In the present article, I present an informal account of my own work in assessing instructional technology for engineering thermodynamics to show not only the benefits, but also the limitations, in studying the technology we create. I conclude by considering several ways of advancing the development of instructional technology within the SCiP community, including interdisciplinary research and envisioning learning contexts that differ radically from traditional learning focused on lectures and testing.     

EFFECT OF GROUP PERFORMANCE ON SUBSEQUENT INDIVIDUAL PERFORMANCE:

Abstract— Does group discussion and deliberation on one issue or task influence the members' decisions or opinions on other issues? In contrast to past research looking solely at changes in responses to the same item discussed by the group, this study examined whether group interaction results in members changing the way they make judgments on related items in the future. The results show that group discussion and consensus on one set of judgments led to a significant convergence of judgmental strategies that extended to a related (but different) set of judgments the members made later as individuals.     

Self-image,perception of peers' risk acceptance and risky shift

Twelve four-person female groups of subjects displaying the typical underestimation of their peers' (relative to their own) risk acceptance were compared with twelve groups of subjects who (slightly) overestimated their peers' risk acceptance. Risk level was measured by responses to a set of hypothetical decision situations known to elicit risky shift on the basis of previous research. Risky shift following group discussion was not found to be different for the two types of groups, casting doubt on the widely suggested role of peer underestimation in risky shift. Nor was risky shift affected by whether or not group members stated their individual decisions publicly at the close of discussion. Larger group risky shifts were accompanied by higher self-ratings given by group members on a number of polarity scales. In discussing the findings, we outline an explanation of group-induced shifts in risk taking, emphasizing the motivational and informational inducements provided by group discussion whereby group members come to discard their prior positions in favor of more aspired ones.     

Differences Between Minority,Majority, and Unanimous Group Members in the Communication of Information

This article integrates research on minority influence and information sampling in groups. The traditional information‐sampling paradigm implies that the discussion bias for common over unique information affects all types of groups universally. We proposed an alternative in which information sampling depends on the composition of opinions. We proposed that groups with a minority opinion may focus more on unique information and that a minority opinion may lead majority members to consider more preference‐inconsistent information. In a study that tested how minority, majority, and unanimous group members differ in their discussion of information, results lent no support for the alternative conception of information sampling. However, when the minority prevailed, minority members repeated significantly more common information than when the majority prevailed.     

Analyse interlocutoire d’une plainte exprimée par une équipe mobile de soins palliatifs

This article points out the merits of conducting an interlocutory analysis of a group meeting held between two administrations of a questionnaire. Here, the Company Climate Questionnaire was filled out individually by the members of the group before and after the meeting. Changed attitudes toward the supervisory staff were observed after the discussion. All participants were members of a mobile palliative care team at a university hospital. The verbal interaction analysis allowed us to identify the collaborative facet of the complaint that surfaced, and to determine what inter - subjective processes arising during the group discussion triggered the expressed changes of opinion.     

Shift toward risk and heterogeneity of groups

Groups that were homogeneous and heterogeneous in terms of risk preferences were varied orthogonally across conditions of information exchange and discussion. The shift toward risk for heterogeneous group members was significantly larger than for homogeneous group members, who did not differ from a control condition. Further analyses showed that two possible alternative hypotheses, time differentials for discussion and regression toward the mean, were not tenable. The data support (a) the “at least as willing” interpretation of Brown's risk-as-value hypothesis, and (b) the necessity of constituting groups for heterogeneity and homogeneity with great care.     

团体决策支持系统和团体讨论对团体决策的影响

通过模拟实验的方法,探讨了团体决策支持系统（GDSS）和团体讨论对团体决策的影响。以大学生为被试,运用小组决策任务,对小组决策过程进行了研究。实验记录了在有无GDSS的支持和有无团体讨论两个变量所决定的4种实验条件下,小组决策取得结果的正确性和组内的一致性。用ANOVA方法分析了4种条件下的实验结果,发现GDSS能提高团体决策的正确性,而团体讨论将有助于成员做出一个正确的、一致的决策     

Using Relative Confidence Judgments to Evaluate Group Effectiveness

The performance of groups can be greatly influenced by their ability to identify their best member. This study investigated this issue in the context of a quantitative judgment task. Relative confidence judgments were used to determine the extent to which group members were able to identify their best member. The effectiveness of groups was also compared across three experimental conditions that varied in terms of the specific instructions group members were given about the group discussion. Results indicate that group members were often able to identify the most accurate member even though the judgment task did not have a demonstrable solution. Groups were also at least as accurate as their best member nearly 40% of the time. The group process intervention that encouraged group members to try to determine the most accurate individual judgment fared better than the intervention that focused on intraindividual accuracy rankings. Groups in this condition also showed the strongest correspondence between identifying the best member and performing at this level. Groups assigned to an unstructured group discussion condition performed nearly as well as those assigned to the more successful of the two interventions.     

Research Agenda to Facilitate Community Participation In HIV Vaccine Research: A Participatory Approach

This article reports on a participatory process to generating a research agenda to guide research on community participation in HIV vaccine research. Community members representing stakeholder parties involved in the HIV vaccine research enterprise were invited to participate in the process. Fourty-five participants participated in the process and we used interactive techniques to stimulate discussion and interaction between community members at different levels of the HIV vaccine research enterprise. Through the process we generated a locally grounded research agenda to guide research on community participation in HIV vaccine research that originates out of the experiences, challenges and concerns of community members.     

Gender Differences in Family Communication About Organ Donation

In this study we investigated gender differences in willingness to donate organs and conversations with family members about organ donation. Results from a snowball sample of 353 men and 488 women (average age = 41–50) indicated that men are less willing to donate and less likely to have conversations about organ donation. When such conversations do occur, men are less likely to include within them topics of conversation that are associated with more positive responses from family members. Women are more likely to include a mention of their desire to donate organs, discussion of the need for organs, and an explanation of why they would/would not like to donate their organs. They are also more likely to mention moral/altruistic/religious reasons for donation or to tell/use a narrative in the discussion. Men, however, more commonly discussed whether signing a donation card would affect medical care. Women report higher agreed compliance from family members. Directions are provided for future research and campaign development by taking these differences into consideration.
