Sequential and myopic: On the use of feedback to balance cost and utility in a simulated electricity efficiency task

While there is extensive research on feedback, little research is aimed at the use of feedback to optimise conflicting goals. A task modelled after In Home Displays for providing feedback about electricity cost was designed to investigate the effects of feedback frequency, detail, and stability, when participants try to balance cost and utility. Frequent feedback proved to be advantageous in a deterministic system, but feedback aggregated over time was advantageous in a system with noisy feedback. Surprisingly, performance was better with noisy feedback, where the probabilism, in effect, acted as a filter, highlighting the applications that are most important for the cost and the utility. Computational modelling suggested that the best-fitting model assumes that the participants are sequential, considering one goal at a time, first satisfying the cost budget, only thereafter trying to maximise the utility, and reflexive, myopically responding primarily to the feedback explicitly available on a given trial.     

Preference or ability: Exploring the relations between risk preference,personality, and cognitive abilities

Key issues in the behavioral sciences are if there exist stable risk preferences that generalize across domains and if these are best measured by revealed risk preference (RRP) in behavioral decision tasks or by surveys eliciting stated risk preference (SRP). We applied network analysis to data from a representative Swedish sample to investigate the relations between RRP, SRP, personality characteristics, and cognitive abilities, using in total over 70 measurements. The results showed that different measures of RRP were poorly intercorrelated and formed a community together with measures of numerical and cognitive abilities. Measures of SRP were weakly correlated with measures of RRP and identified in a distinctly separate community, along with personality characteristics and gender. The ensuing analyses provided support for a model suggesting that RRPs are contaminated by demands on numerical and cognitive abilities. RRPs may thus suffer from poor construct validity, whereas SRPs may better capture people's everyday risk preferences because they are related to more stable traits.

Feedback in Couple and Family Therapy: A Randomized Clinical Trial

Routine Outcome Monitoring (ROM) is recommended as a psychotherapy procedure to serve as clinical feedback in order to improve client treatment outcomes. ROM can work as a warning signal to the therapist if the client shows signs of no change or deterioration. This study has investigated whether any difference in outcome could be detected between those clients in couple and family therapy who used the Systemic Therapy Inventory of Change (STIC) feedback system (ROM condition) versus those who were offered treatment without the use of STIC (“treatment as usual” or TAU condition). A sample of 328 adults seeking couple and family therapy in Norway was randomly assigned to ROM versus TAU conditions. Outcome measures were The Outcome Questionnaire–45 and The Revised Dyadic Adjustment Scale. The results demonstrated no significant differences in outcomes between the ROM and TAU. Possible explanations of this result related to design and implementation issues are discussed.     

Linda versus World Cup: Conjunctive Probabilities in Three-event Fictional and Real-life Predictions

Conjunction errors in probability judgments have been explained in terms of representatives, non-normative combination procedures, and linguistic, conversational, or conceptual misunderstandings. In two studies, a three-event variant of the classical Linda scenario (Tversky and Kahneman, 1983) was contrasted with estimates of Norway’s chances in three coming World Cup soccer matches. Conjunction errors occurred even in the latter, real-life prediction task, but much less frequently than in the fictional Linda case. Magnitude of the conjunction effect was found to be dependent upon type of constituent (fictional versus dispositional), unequal versus equal probabilities of constituent events, prediction of positive versus negative outcomes, and, for real-life predictions only, umber of constitutent events. Fictional probability ratings were close to but lower than representativenss ratings, giving evidence for a representativeness and adjustment-for-uncertainty strategy, whereas probabilities of real-life events were given a causal model interpretation.     

Validation of an ipsative personality measure (DISCUS)

The purpose of this study was to examine the construct validity of an ipsative personality test (DISCUS), and various effects of the ipsative format of the test. Both an ipsative and a normative version of the DISCUS test was administered to a sample of undergraduate students (N = 103), along with an adjective based personality test that measures the Big-Five personality traits (5PFa). The results indicated that the normative and the ipsative version of DISCUS are not equivalent, and caution is needed when using the ipsative version for psychometric evaluations as in validation studies. The four DISCUS dimensions (Dominance, Influence, Stability, and Carefulness) represented combinations of the Big-Five traits rather than independent traits as indicated by the correlations with the Big-Five measure.     

Defining Discrimination in the Personal/Group Discrimination Discrepancy

Members of low-status groups typically report that their group experiences more discrimination than they do personally, a phenomenon referred to as the personal/group discrimination discrepancy. It is hypothesized that manipulating the meaning of discrimination affects the personal/group discrimination discrepancy. In three studies, 301 female undergraduates (259 Whites; 42 non-Whites) from a large midwestern university read vignettes depicting discriminatory events that varied according to severity and frequency. Participants in high-frequency conditions perceived both more personal and group discrimination than low-frequency participants, and they showed smaller personal/group discrepancies. This effect was found for work-related discrimination and social sexism. Results indicate that severe and infrequent events are what people typically think of as discrimination and that using the term discrimination affects personal and group judgments. The importance of defining discrimination when investigating the personal/group discrimination discrepancy is discussed.     

Dynamic brain imaging: Event-related optical signal (EROS) measures of the time course and localization of cognitive-related activity

This paper describes the concept of dynamic brain imaging and introduces a new methodology, the event-related optical signal, or EROS. Dynamic brain imaging allows one to study noninvasively the time course of activity in specific brain areas. Brain imaging data can contribute to the analysis of the subcomponents of the human information processing system and of their interactions. Several brain imaging methods provide data that possess spatial and temporal resolution at various degrees and can be used for this purpose. In this paper, we focus on the EROS method, which yields data with millisecond temporal resolution and subcentimeter spatial resolution. We describe the fundamentals of this method and report several examples of the types of data that can be obtained with it. Finally, we discuss the possibility of combining different imaging methods, as well as the advantages and limitations that can be expected in this process.
