The cost of richness: the effect of the size and diversity of decision sets on post-decision regret

Decision making is often made difficult by the knowledge that one has to live with the outcomes of one's choices and with the regret that these might engender. Formal theories propose that regret is proportional to the difference between the outcome of the option chosen and the expected outcome of the next best alternative that one may have chosen instead. It follows that the number of alternatives available for choice does not affect post-decisional regret. In this study, however, the authors proposed that regret is related to the comparison between the alternative chosen and the union of the positive attributes of the alternatives rejected. This general proposition yielded 2 hypotheses: (a) the larger number of alternatives from which one can choose and (b) the more diverse those alternatives are, the stronger the regret that an unsatisfactory choice would cause. These hypotheses were tested and supported by 4 experiments.     

To what extent do investors in a financial market anchor their judgments excessively? Evidence from the Hong Kong horserace betting market

A naturalistic study was employed to explore a new form of “basic anchoring.” In particular, we examined the degree to which decision makers in a financial market, the horserace betting market, anchored their probability judgments excessively on a factor present in the environment at the time the judgments were made and which was relevant and informative to the judgment: the advantage afforded by a horse's barrier‐position (BP). The results demonstrated that under certain conditions bettors anchored excessively on BP information revealed at previous race meetings, but not on the most recent race outcomes. In fact, bettors appeared to use the most recent race outcomes appropriately when forming probability estimates; but only when the results were in line with, what were likely to be, their expectations of BP advantage. Bettors with varying levels of expertise were shown to be subject to excessive anchoring, although greater expertise was generally associated with less excessive anchoring. The paper concludes that the manner and degree of basic anchoring in real‐world environments is complex. Copyright © 2009 John Wiley & Sons, Ltd.     

The effects of an interactive cognitive task (ICT) in suppressing fatigue symptoms in driving

BackgroundProlonged drive on inter-urban, monotonous roads has the potential of causing a decrease in the general level of arousal leading to a state of underload and fatigue. This study examines the effectiveness of an interactive cognitive task (ICT) in delaying fatigue symptoms induced by underload conditions. The ICT is an auditory-motor task which is based on the basic principles of a knowledge game known as “Trivia”.MethodTen participants took part in two experimental sessions of 140 min drive in a fixed-base simulator. In a within-subject counterbalanced design one session consisted of driving without ICT and the other included ICT operation. In the ICT session the game was activated after 60 min of driving.ResultsWhen activated, the ICT increased physiological indicators of arousal, increased subjective feelings of alertness, and improved driving performance. The physiological and driving performance measures revealed that the ICT activation had an immediate but localized influence on arousal. Post-drive questionnaires showed that in the ICT condition, the participants’ level of motivation increased and their feelings of sleepiness decreased.ConclusionsEngaging in cognitive tasks can counteract the effects of underload and increases driving safety as long as they are active. However, additional research is necessary to determine the effects of long term use.     

Full House of Fears: Evidence That People High in Attachment Anxiety Are More Accurate in Detecting Deceit

Lying is deep‐rooted in our nature, as over 90% of all people lie. Laypeople, however, do only slightly better than chance when detecting lies and deceptions. Recently, attachment anxiety was linked with people's hypervigilance toward threat‐related cues. Accordingly, we tested whether attachment anxiety predicts people's ability to detect deceit and to play poker—a game that is based on players' ability to detect cheating. In Study 1, 202 participants watched a series of interpersonal interactions that comprised subtle clues to the honesty or dishonesty of the speakers. In Study 2, 58 participants watched clips in which such cues were absent. Participants were asked to decide whether the main characters were honest or dishonest. In Study 3, we asked 35 semiprofessional poker players to participate in a poker tournament, and then we predicted the amount of money won during the game. Results indicated that attachment anxiety, but not other types of anxiety, predicted more accurate detection of deceitful statements (Studies 1–2) and a greater amount of money won during a game of poker (Study 3). Results are discussed in relation to the possible adaptive functions of certain personality characteristics, such as attachment anxiety, often viewed as undesirable.     

Impaired skill learning in patients with severe closed-head injury as demonstrated by the serial reaction time (SRT) task

A group of 20 patients who sustained closed-head injury (CHI) and a matched control group of 20 individuals were tested on the serial reaction time (SRT) task. Three different sequence-learning measures were generated from the task: two implicit and one explicit. The two implicit sequence-learning measures include: (1) the learning rate on the first five blocks of the repeated sequence, assumed to reflect primarily general reaction time learning, and (2) the difference between the fifth block of the repeated sequence and the sixth block, a random sequence that reflects implicit sequence-specific learning. In addition, an explicit measure of sequence learning was generated. The results indicate that the CHI group was impaired on the explicit measure of sequence learning. The groups did not differ on general reaction time learning, one of the implicit measures of sequence learning. However, the control group was superior to the CHI group in learning the specific sequence repeated in the SRT task. This pattern of results is unique to the CHI group, corresponding with neither that of amnesic patients nor with that of patients with dysfunction of the basal ganglia (i.e., Parkinson's diseases).     

Patients’ Attitudes Towards Disclosure of Genetic Test Results to Family Members: The Impact of Patients’ Sociodemographic Background and Counseling Experience

Many factors predict the intention to disclose genetic information to relatives. The article examines the impact of patients’ socio-demographic factors on their intention to disclose genetic testing results to their relatives. Data were collected in eight genetic clinics in Israel. Patients were requested to fill in a questionnaire after counseling. A convenience sample of 564 participants who visited these clinics was collected for a response rate of 85 %. Of them, 282 participants came for susceptibility testing for hereditary cancers (cancer group), and 282 for genetic screening tests (prenatal group). In the cancer group, being secular and having more years of education correlated positively with the intention to disclose test results to relatives. In the prenatal group, being married and female correlated positively with the intention to disclose. In the cancer group, being religious and with less years of education correlated positively with the view that the clinician should deliver the results to the family. In the prenatal group, being male and unmarried correlated positively with this belief. In both groups, being of young age correlated with the perception that genetic information is private. Varied sociodemographic factors affect the intention to inform family members. Thus, knowing the social background of patients will shed light on people’s attitudes to genetic information and will help clinicians provide effective counseling in discussions with patients about the implications of test results for relatives.     

Therapist empathy,homework compliance,and outcome in cognitive behavioral therapy for generalized anxiety disorder: partitioning within- and between-therapist effects

Although client-perceived therapist empathy relates to positive therapy outcomes, including in cognitive behavioral therapy (CBT), little is known about how empathy exerts its ameliorative effect. One possible way is by promoting clients’ subsequent homework compliance, a variable that also predicts positive outcomes in CBT. The present study sought to investigate simultaneously, in the context of 43 therapist–client dyads receiving 15 sessions of CBT for generalized anxiety disorder, (1) the association of early client-perceived therapist empathy (averaged over sessions 1, 3, 5) with mid-treatment client homework compliance (averaged over sessions 6, 8, 10); (2) the association of mid-treatment homework compliance on client posttreatment worry severity; and (3) the indirect effect of early perceived therapist empathy on posttreatment worry through mid-treatment homework compliance. Given that clients were nested within therapists, we examined both within- and between-therapist differences in clients’ ratings of therapist empathy and homework compliance, and tested both of these indices as predictors of the relevant dependent variables in a multilevel model. At the within-therapist level (i.e., differences between clients within a given therapist’s caseload), greater early empathy was associated with greater mid-treatment homework compliance. At the between-therapist level (i.e., differences between therapists across all of their cases), greater between-therapist homework compliance was related to lower posttreatment worry. Finally, homework compliance was not found to mediate the relationship between empathy and posttreatment outcome. The results underscore the importance of parsing client and therapist effects, and are discussed with regard to their training and research implications.     

Stress factors,social support,and violence in Israeli society: A quantitative analysis

In the present study violence in Israel for a period of 32 years (1950-1981) was analyzed, within a stress model according to which the probability of violence and agression as a reaction to stress will increase when social support systems fail or malfunction. Following this model, three types of variables were identified: 1. Measures of stress and social change: to the regular social stressors (i.e., inflation and unemployment), we added two measures of affluence (income per capita and rates of cars) as well as population density. 2. Measures of social support: rates of birth to unmarried mothers and marriage and divorce rates served as measures of the strength of the family. Another measure in this category was rates of psychiatric hospitalization. 3. Measures of violence: in addition to rates of homicide, robbery, and all offenses, inward directed aggression (suicide) was included in this category. At the first stage of the data analysis, Guttman's Smallest Space Analysis (SSA-1) was applied, providing a two-dimensional space diagram of the correlations between the variables. At the second stage, a multiple regression analysis was introduced. The findings indicate that the theoretical model received substantial support mainly from four stress measures (inflation, income per capita, cars, and population density) and one measure of social support (divorce). Unemployment contributed significantly (in the expected direction) only to homicide. Some theoretical implications of the findings, as well as their relevance to some developments in Israeli society are discussed, and suggestions are made for future research.

Relationship Quality among Chronically Ill Children and their Parents

The present study examined the quality of parent–child relationships as reported by 383 parents of chronically ill children. The medical condition category, child’s mobility, education type and childcare assistance were examined. Parents answered the Parent–Child Relationship Inventory (PCRI). In addition, 45 parents of chronically ill children were interviewed. The results indicated a significant difference in most aspects of the PCRI (limit setting, promotion of autonomy, communication, satisfaction and involvement) across medical condition categories. Further child variables (mobility, assistance and education type) had an effect on the PCRI subscales as well. Interview analysis revealed a difference in the reported quality of parent–child relationships between medical conditions categories. Parents of mentally ill children primarily felt anger and guilt in their relationship with their ill children, whereas parents of children with cancer and autoimmune disease primarily felt depressed. Our results suggest the need for further study of parent–child relationships in and between different chronic childhood medical conditions in an attempt to address parents’ and children’s needs in an optimal way.
