Travel choice and the goal/process utility distinction

The concept of utility emanating from decision theory is employed in applied research aiming to understand and forecast the travel choices the general public make. Related to a distinction between telic and autotelic motivational theories, it is argued that in this area the prevalent definition of utility as goal-related evaluations of outcomes of activities (goal utility) needs to be complemented by the notion that utility is also experienced from performing the activities themselves (process utility). The validity of the distinction thus introduced between goal and process utility was demonstrated empirically in two studies of choices of travel destinations. In Experiment 1, one group of students rated the likelihood of patronizing fictitious grocery stores and another group rated the likelihood of impulse purchases in these stores. In addition to travel time, the rated likelihood of patronizing the stores was independently affected by the number of desirable goods available to purchase (goal utility) and the quality of personal services provided by staff (process utility). In contrast, the rated likelihood of impulse purchases was only affected by the latter. In Experiment 2, similar results were obtained for choices of fictitious grocery stores by a representative sample of car-owning households participating in a travel survey.     

Combining whole-school and targeted programs for the reduction of bullying victimization: A randomized,effectiveness trial

Despite the extensive evaluation of school-based interventions for bullying, victimization remains a significant problem in schools. Bullying victimization is significantly predicted by contextual (school-related) factors. As a consequence whole-school programs have been commonly used to prevent and reduce bullying victimization. Evidence also points to individual risk factors (such as emotional distress) in predicting victimization, yet programs to prevent bullying victimization by changing these individual risks are far less developed. Few studies have approximated “real-world” implementation conditions in their trials. The current effectiveness trial evaluated the combination of a whole-school program designed to prevent bullying perpetration and victimization together with a targeted intervention for at-risk students, teaching them individual and dyadic strategies to reduce their anxiety and manage victimization, allowing schools some latitude to implement programs as they typically would. Students from Grades 3 and 4 (N = 8,732) across 135 schools were randomly assigned to one of four conditions: combined intervention; whole-school intervention only; individual intervention only; and care as usual. Victimization decreased significantly and similarly across all four conditions at 12 and 24 months following baseline. Similar reductions and failure to discriminate conditions were found on other key constructs: anxiety; bullying perpetration; and depression. Possible reasons for the failure to demonstrate victimization prevention differences and lessons learned from this large, effectiveness trial are considered.     

Impact of decision goal on escalation

This research investigates the sunk-cost effect or escalation defined as the irrational tendency to choose to continue to invest money, time, or effort following unsuccessful investments. Building on previous research demonstrating a loss-sensitivity principle in sequential decision making, the hypothesis was proposed that a loss-minimization goal would lead to stronger effects of sunk outcomes (prior gains and losses) than would a gain-maximizing goal. The hypothesis was investigated in three experiments with undergraduates responding to investment decision scenarios. Although the tendency to continue investments was always larger for gain-maximizing than for loss-minimizing goal instructions, the sunk-outcome effect was stronger in the former case. However, when the decisions were personal and concerned lower stakes rather than business investments involving large amounts of money, the expected stronger effect of sunk outcomes was found for loss-minimizing goal instructions. Another finding was that the expected value was never ignored, thus suggesting that future research should focus on the joint effects of the expected value and sunk outcomes.     

Outcome-Desirability Bias in Resource Management Problems

Sequences of numbers representing prior resource size were presented to participants in a common-pool resource dilemma. The numbers were sampled from uniform probability distributions with either a low variance (low resource uncertainty) or a high variance (high resource uncertainty). Presentations were both sequential and simultaneous. Three groups of 16 undergraduates either estimated the size of the resource when it did not represent value to them; requested an amount from the resource, identified with a sum of money, when the outcome of the requests only depended on resource size; or requested from the resource (sum of money) when the outcome of the requests depended on both resource size and how much others in a group requested. In support of an individual outcome-desirability bias due to selective recall of the number sequences, after sequential presentation larger requests were observed when resource uncertainty was high than when it was low. No effects of resource uncertainty or presentation were found on the estimates of resource size. Whether or not the outcome of the requests depended on others' requests made little difference.     

Cognitive deficits in relation to personality type and hypothalamic-pituitary-adrenal (HPA) axis dysfunction in women with stress-related exhaustion

Exhaustion caused by long-term work-related stress may cause cognitive dysfunction. We explored factors that may link chronic stress and cognitive impairment. Personality, psychiatric screening, and behavior were assessed by self-reporting measures in 20 female patients (mean age 39.3 years; range 26-53) with a preliminary diagnosis of stress-related exhaustion and in 16 healthy matched controls. Cognitive performance was investigated with a detailed neuropsychological test battery. Cortisol axis function was assessed by urinary and saliva collections of cortisol, dexamethasone suppression, Synacthen response, and corticotropin-releasing hormone (CRH) tests. Proinflammatory cytokines were measured. Hippocampal volumes were estimated by magnetic resonance imaging. Multivariate and univariate statistical methods were used to explore putative differences between groups and factors linked to cognitive impairment. Cognitive function clearly differed between groups, with decreased attention and visuospatial memory in the patient group, suggesting frontal cortex/medial temporal cortex-network dysfunction. Increased harm avoidance and persistence was present among patients, with lowered self-directedness linked to lower quality of life, increased anxious and depressive tendencies, and experiences of psychosocial stress. Attention was decreased with concomitantly impaired visuospatial memory. The pituitary (adrenocorticotropic hormone, ACTH) response to CRH was decreased in patients, with an increased cortisol/ACTH response to CRH. However, cortisol production rates, diurnal or dexamethasone-suppressed saliva cortisol levels, and the cortisol response to Synacthen were unaltered. Hippocampal volumes did not differ between groups. These findings suggest that cognitive dysfunction in stress-related exhaustion is linked to distinct personality traits, low quality of life, and a decreased ACTH response to CRH.     

Activity rescheduling: reasoned or habitual?

Utility maximization is widely used to model individuals’ activity scheduling and rescheduling behavior. Utility maximization is based on the assumption that the modeled behavior is the result of a reasoned decision. An alternative to a planned behavior is habitual behavior, whose execution process has become automatic due to its repeated performance. Compared to activity scheduling, little is known about the activity rescheduling behavior. In this paper, we focus our attention on the rescheduling behavior. We step back and ask a basic question: is the activity rescheduling behavior reasoned or habitual? Our initial expectation is that rescheduling behavior is mostly habitual behavior due to its feature of repeated performance. We answer this question by conducting an experiment. Results from the experiment confirm our original null hypothesis that rescheduling behavior is mostly a habitual behavior.     

Social influence on predictions of simulated stock prices

Herding in financial markets refers to that investors are influenced by others. This study addresses the importance of consistency for herding. It is suggested that, in financial markets perceptions of consistency are based on repeated observations over time. Consistency may then be perceived as the agreement across time between investors' predictions. In addition, consistency may be related to variance over time in each investor's predictions. In an experiment using a Multiple Cue Probability Learning paradigm, 96 undergraduates made multi‐trial predictions of future stock prices given information about the current price and the predictions made by five fictitious others. Consistency was varied between the others' predictions (correlation) and within the others' predictions (variance). The results showed that the predictions were significantly influenced by the others' predictions when these were correlated. No effect of variance was observed. Hence, participants were influenced by the others when they were in agreement, regardless of whether they varied their predictions over trials or not. Copyright © 2008 John Wiley & Sons, Ltd.     

The development of reflection-impulsivity: further data

The MFF20 was administered to 617 children aged 7–12yr. The resulting development trends for latency and errors suggest errors decrease to about age 10 yr then level off while a corresponding, though less dramatic, increase in latency was observed. These results were obtained without evidence of ceiling or floor effects or any evidence of a decrease in the relationship between latency and errors after age 10 yr, in contrast to those obtained by Salkind and Nelson (1980).     

STUDIES IN VISUAL PERCEPTION OF ARCHITECTURAL SPACES AND ROOMS

G arling T. Studies in visual perception of architectural spaces and rooms. V. Aesthetic preferences. Scand. J. Psychol ., 1972. 13 , 222–227.—Depicted urban spaces were rated by 24 subjects with respect to pleasantness. The results for colour photographs, 'detailed' and 'undetailed' perspective drawings were compared. As a common basis for aesthetic preferences, the factors 'variation', 'umbrageousness' and 'openness' were suggested. These factors accounted for 69 % of the variance in multiple linear regression.
