Telematics: Decision Time for Detroit

BUSINESS STRATEGY REVIEW, Issue 2 2001
Anjan Chatterjee
With implications for navigation, safety, entertainment and vehicle maintenance as well as regulation and infrastructure investment in roads, telematics has the potential to transform driving more than any other innovation for decades. In the already well-established Asian telematics industry, revenue tends to come from extra charges at the time of vehicle-sale, with most subsequent services provided free. The US model has evolved differently, with much of the cost of telematics hardware and software subsidized in the initial vehicle sale price and revenue coming from services used. The decision to invest in telematics is therefore riskier in the US. This article first briefly summarizes the potential of telematics. It then analyzes the investment risks, particularly for automakers. It concludes with recommendations on how the US auto industry can minimize risk and make the most of the opportunities. [source]

Characterizing visual behaviour in a lineup task,

APPLIED COGNITIVE PSYCHOLOGY, Issue 7 2009
Jamal K. Mansour
Eye tracking was used to monitor participants' visual behaviour while viewing lineups in order to determine whether gaze behaviour predicted decision accuracy. Participants viewed taped crimes followed by simultaneous lineups. Participants (N,=,34) viewed 4 target-present and 4 target-absent lineups. Decision time, number of fixations and duration of fixations differed for selections vs. non-selections. Correct and incorrect selections differed only in terms of comparison-type behaviour involving the selected face. Correct and incorrect non-selections could be distinguished by decision time, number of fixations and duration of fixations on the target or most-attended face and comparisons. Implications of visual behaviour for judgment strategy (relative vs. absolute) are discussed. Copyright © 2009 John Wiley & Sons, Ltd. [source]

Odor-mediated patch choice in the parasitoid Venturia canescens: temporal decision dynamics

ENTOMOLOGIA EXPERIMENTALIS ET APPLICATA, Issue 2 2009
Yin-Quan Liu
Abstract Parasitoids foraging for hosts in a heterogeneous environment would greatly benefit if they could decide already from a distance in which areas search for resources would be most profitable and to avoid areas of low fitness returns. Interestingly, the temporal dynamics of the decision process in parasitoid patch choice have rarely been investigated. In a Y-tube olfactometer, we tested whether thelytokous and arrhenotokous females of the parasitoid wasp Venturia canescens (Gravenhorst) (Hymenoptera: Ichneumonidae) respond to differences in cues indicating the quality of a host-containing patch and choose more profitable patches. Special attention was given to the time it took females to make their choices (patch choice time) when differences in patch quality were either qualitative (absence vs. presence of hosts and kairomone) or quantitative (various concentrations of hosts and kairomone, and presence of competitors). We found that both thelytokous and arrhenotokous wasps only chose the higher-quality patch based on odor cues when the difference was qualitative. When patches differed only with respect to the number of hosts, or the presence or absence of competing female parasitoids, no significant preference could be found in females of either strain of the parasitoid. In contrast, both the time until females reached the junction of the Y-tube olfactometer (response time) and the time until females decided for either patch (decision time) varied with parasitoid strain and odor treatment. Thelytokous wasps were faster than arrhenotokous wasps in their response time and in their decision time. However, females of both strains responded faster with increasing number of total hosts releasing kairomone. Yet, decision time for patches did not significantly vary as a function of patch quality offered to Venturia wasps. [source]

On undesirable consequences of thinking: framing effects as a function of substantive processing

JOURNAL OF BEHAVIORAL DECISION MAKING, Issue 2 2007
Eric R. Igou
Abstract Three studies investigate the impact of effortful constructive processing on framing effects. The results replicated previous findings: Participants avoided the risky option when the scenario was framed in terms of gains, but preferred this option when the scenario was framed in terms of losses. Importantly, framing effects were most pronounced when conditions allowed for an effortful constructive processing style (i.e., substantive processing). This impact of decision frames varied when decision time served as an indicator for the elaboration extent (Study 1), and also when processing motivation (accountability; Study 2) and processing ability (decision time; Study 3) were manipulated. Moreover, effortful processing did not increase framing effects when contextual cues reduced the necessity for constructive thinking (Study 1). We suggest that decision frames may take on very different roles as a function of the ambiguity of the decision problem, and the degree and style of processing.

Rumination fosters indecision in dysphoria,

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 3 2010
Annette van Randenborgh
Abstract This study investigated the effects of rumination on indecision, assessed as high levels of perceived decision difficulty, low confidence in a decision, and decision latency. Dysphoric and nondysphoric participants were assigned to either a rumination or a distraction induction. Subsequently, they made four decisions with alleged real-life consequences. As predicted, rumination exhibited a negative effect on dysphoric participants' decision-making process. They experienced the decisions as more difficult and had less confidence in their choices. No effects emerged on the measure of decision time. Mediation analyses revealed that increased difficulty of the decisions was due to self-focused thinking as a cognitive consequence of rumination, while reduced confidence in the decisions was partly mediated by negative affect that resulted from rumination. The finding that rumination affects the important life domain of decision making by fostering indecision in dysphoric individuals is a central extension of previous studies on rumination's consequences. In addition, these results provide insight into the depressive symptom of indecisiveness by revealing its underlying mechanisms. © 2009 Wiley Periodicals, Inc. J Clin Psychol 66: 229,248, 2010.

Testing the boundaries of the choice overload phenomenon: The effect of number of options and time pressure on decision difficulty and satisfaction

PSYCHOLOGY & MARKETING, Issue 3 2009
Graeme A. Haynes
The number of alternatives available to people in many day-to-day decisions has greatly increased in Western societies. The present research sought to build upon recent research suggesting that having large numbers of alternatives can sometimes have negative consequences for individuals. In the present experiment, participants were presented with descriptions of either 3 or 10 prizes and asked to choose one, for which they were to be entered in a drawing. The number of alternatives was manipulated in conjunction with the amount of time people were allotted to make a decision (limited vs. extended decision time). Following their decisions, participants completed measures of decision-related difficulty, task enjoyment, satisfaction, and regret. Participants given a limited amount of time to choose with a larger set of alternatives found their decisions to be more difficult and frustrating than did participants in the other conditions. The larger set of alternatives led to less satisfaction, but not less regret, with people's decisions. Implications for research on the choice overload phenomenon are discussed. © 2009 Wiley Periodicals, Inc. [source]

Varieties of sameness: the impact of relational complexity on perceptual comparisons,

COGNITIVE SCIENCE - A MULTIDISCIPLINARY JOURNAL, Issue 3 2004
James K. Kroger
Abstract The fundamental relations that underlie cognitive comparisons,"same" and "different",can be defined at multiple levels of abstraction, which vary in relational complexity. We compared response times to decide whether or not two sequentially-presented patterns, each composed of two pairs of colored squares, were the same at three levels of abstraction: perceptual, relational, and system (higher order relations). For both 150 ms and 5 s inter-stimulus intervals (ISIs), both with and without a masking stimulus, decision time increased with level of abstraction. Sameness at lower complexity levels contributed to decisions based on the higher levels. The pattern of comparison times across levelswas not predictable solely from encoding times. The results indicated that relations at multiple levels of complexity can be abstracted and compared in working memory, with higher complexity levels requiring more processing time. We simulated the impact of relational complexity on response time using Learning and Inference with Schemas and Analogies (LISA), a computational model of relational comparisons based on dynamic binding of elements into roles in a relational working memory.

Personality and lexical decision times for evaluative words

EUROPEAN JOURNAL OF PERSONALITY, Issue 2 2010
Peter Borkenau
Abstract We studied personality influences on accessibility of pleasant and unpleasant stimuli in a sample of 129 students. Self-reports and reports by knowledgeable informants on extraversion, neuroticism, approach temperament and avoidance temperament were combined with a go/no-go lexical decision task that included pleasant, unpleasant and neutral words, and two response modes, manual and vocal. The data were analysed using multilevel modelling. Extraversion and approach temperament predicted faster identification of pleasant words than of neutral and of unpleasant words. Vocal responses took longer than manual responses, but mode of response did not interact with the valence of the words. Copyright © 2009 John Wiley & Sons, Ltd. [source]

Automatic effects of deviancy cues on creative cognition

EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 3 2005
Jens Förster
Three experiments test the existence of an automatic deviancy-creativity link. Using a lexical decision task, in Experiment 1 we found a semantic link between deviancy and creativity words in that decision times for creativity-related words were enhanced after subliminal deviancy priming. In Experiment 2, participants were led to think about either a punk or an engineer and afterwards were administered creative insight and analytical reasoning problems. According to a pretest, punks and engineers were judged as differing in uniqueness but not in creativity. Participants given ,punk' priming solved more creative insight problems and fewer analytical reasoning problems than those given ,engineer' priming. In Experiment 3, participants were incidentally exposed to abstract artworks symbolically expressing either the concept of conformity or deviancy and were subsequently asked to solve a creative generation task. Exposure to the artwork representing deviancy led to generation of more creative solutions than exposure to that representing conformity. Copyright © 2005 John Wiley & Sons, Ltd. [source]
