Attribute‐based differentiation of alternatives

An intermediate step is introduced to the dialogue decision process for decision analysis. Alternatives are refined after they have been generated within a strategy table but before they are subject to more detailed evaluation. Two or more judges create a subjective mapping from alternatives to attributes that will later be mapped to criteria. In strategy tables, each of the alternative strategies consists of a coherent set of choices made across several decisions that are to be coordinated. These strategic alternatives are modified so as to increase their differentiation in the attribute space, rather than in the decision space alone. When criteria weights are unknown, the best alternative from the modified set may be superior to the best alternative from the original set. Furthermore, analysis of the resulting alternatives may yield a better mapping of the value response surface for the action space, in the sense that this mapping leads to eventual construction of a higher value alternative. Results are reported for a consulting engagement incorporating the proposed step. Copyright © 2003 John Wiley & Sons, Ltd.     

Proactive and reactive aggression in early adolescence as precursors to anti- and prosocial behavior in young adults

Three groups of adolescents who were 14 years old in 1974 were formed on the basis of peer nominations and teacher ratings in an ongoing longitudinal study: 1) reactively aggressive (REA) individuals who displayed reactive, that is, self-defensive aggression but not proactive aggression (43 boys, 35 girls); 2) proactively aggressive (PROA) individuals who attacked another person without a reason (56 boys, 35 girls); and 3) nonaggressive (NONA) individuals who were low in proactive and reactive aggression (48 boys, 45 girls). The groups were compared at ages 8, 14, and 27 in variables representing the constructs of a two-dimensional model of emotional and behavioral regulation. The REA Ss were characterized by higher self-control, especially constructiveness, at each age and better adult adjustment than the PROA Ss. The PROA males were prone to externalizing problems and criminality in adulthood, whereas the PROA females were prone to internalizing problems and neuroticism in adulthood. Both exhibited conduct problems in adolescence, and became heavy users of alcohol in adulthood. The PROA Ss had more children at age 27 than the other Ss. © 1996 Wiley-Liss, Inc.     

How Power States Influence the Persuasiveness of Top‐Dog versus Underdog Appeals

Although both top‐dog and underdog positioning appeals are widely used in marketing and advertising, little is known about which strategy is more effective in persuading consumers. By introducing a sense of power, a social variable that is inherently relevant to the nature of the top‐dog versus underdog classification, we propose that consumers' responses to these two appeals are influenced by their psychological experience of power. Specifically, low‐power consumers will respond to top‐dog appeals more favorably because associating with top dogs facilitates power restoration. In contrast, high‐power consumers will respond to underdog appeals more favorably because supporting underdogs facilitates power expression. In four experimental studies, we provide consistent support for our main predictions as well as the underlying processes. Studies 1 and 2 demonstrate the differential effect of consumers' power states on their attitudes toward top‐dog versus underdog appeals. Providing process evidence, Studies 3 and 4 identify boundary conditions under which the basic effect was eliminated. These findings contribute to the persuasion literature and power research and provide important implications for positioning strategy and advertisement development.     

The effect of presentation format and encoding strategy on associative memory distortion

IntroductionPrevious studies using semantically related words revealed more accurate memory when the items were encoded visually rather than auditorily and when mental images were created during encoding. However, how the level of memory distortion is affected by the creation of different mental imagery formats or by techniques that should suppress generation of mental images has rarely been investigated.ObjectiveThe aim of the present studies was to investigate the ways in which the encoding strategy affects the accuracy of memory reports for two presentation formats of semantically related words: verbal and pictorial.MethodIn experiment 1, the participants were asked to memorize either pictures or their verbal equivalents (words) from the same category, using one of two encoding strategies: uttering the words or counting backwards. In experiment 2, pictorially or auditory presented material was encoded together with the creation of either visual or auditory mental images of the items. The results of the experimental groups were compared to control groups that received no specific instruction.ResultsHigher levels of false recognition, together with lower rates of correct recognition, were observed for words, presented either visually or auditory, relative to pictures. Moreover, self-generation of additional code during the processing of information favored the reduction of false recognitions.ConclusionEncoding strategies that engaged dual coding reduced false recognition. The results are discussed within the distinctiveness heuristic phenomenon.     

The impact of familiarization strategies on the missing-letter effect

When reading a text and searching for a target letter, readers make more omissions of the target letter if it is embedded in frequent function words than if it is in rare content words. While word frequency effects are consistently found, few studies have examined the impacts of passage familiarity on the missing-letter effect and studies that have present conflicting evidence. The present study examines the effects of passage familiarity, as well as the impacts of passage familiarization strategy promoting surface or deep encoding, on the missing-letter effect. Participants were familiarized with a passage by retyping a text, replacing all common nouns with synonyms, or generating a text on the same topic as that of the original text, and then completed a letter search task on the familiar passage as well as an unfamiliar passage. In Experiment 1, when both familiar and unfamiliar passages use the same words, results revealed fewer omissions for the retyping and synonyms conditions. However, in Experiment 2, when different words are used in both types of texts, no effect of familiarization strategy was observed. Furthermore, the missing-letter effect is maintained in all conditions, adding support to the robustness of the effect regardless of familiarity with the text.     

工作记忆成分的年龄相关差异对算术策略运用的预测效应

Holistic Information Integration in Child Decision Making

Weighted‐additive (WADD) strategies require decision makers to integrate multiple values weighted by their relevance. From what age can children make choices in line with such a WADD‐strategy? We compare multi‐attribute decisions of children (6–7; 8–10; 11–12‐year‐olds) with adults in an open information‐board environment without pre‐decisional information search. In two experiments, we classify decision strategies based on individual choice patterns and find that in all age groups the majority of participants are users of a WADD‐strategy. Simple decision heuristics such as lexicographic strategies were applied rarely by children and not at all by adults. In two additional follow‐up studies, we further investigate the underlying process of WADD‐application by analysing decision latencies in combination with a retrospective think‐aloud study. Results suggest that children did not apply WADD‐strategies in a deliberate fashion in our experiments. Overall, our findings demonstrate that the ability to make good and quick decisions by holistically integrating information is already present in young children.

The Influence of Time Estimation and Time‐Saving Preferences on Learning to Make Temporally Dependent Decisions from Experience

In this paper, we merge research related to experiential learning, temporal perception, and the value of time and money by examining decisions where the timing of action (response) determines the outcome received. We predicted that time‐saving preferences and impatience would decrease maximization (i.e., taking action when it returned the largest reward), and that the constraints of temporal perception would compound their effects. Across three studies, participants undershot on average (i.e., responded earlier than the period of time during which a response would return the maximal reward) showed a preference for shorter‐delay options and often did not find the maximal reward. In addition, participants' reliance on temporal perception increased undershooting, increased preferences for shorter‐delay options, and reduced maximization. Nevertheless, participants who found the maximal reward continued to maximize at a high rate rather than opting for shorter delays and smaller rewards. Thus, while most participants appeared to have a preference for saving time, most behaved as reward maximizers rather than temporal discounters. Copyright © 2017 John Wiley & Sons, Ltd.
