Properties of the diversity effect in category-based inductive reasoning

Four experiments investigated how people judge the plausibility of category-based arguments, focusing on the diversity effect, in which arguments with diverse premise categories are considered particularly strong. In Experiment 1 we show that priming people as to the nature of the blank property determines whether sensitivity to diversity is observed. In Experiment 2 we find that people's hypotheses about the nature of the blank property predict judgements of argument strength. In Experiment 3 we examine the effect of our priming methodology on people's tendency to bring knowledge about causality or similarity to bear when evaluating arguments, and in Experiment 4 we show that whether people's hypotheses about the nature of the blank property were causal predicted ratings of argument strength. Together these results suggest that diversity effects occur because diverse premises lead people to bring general features of the premise categories to mind. Although our findings are broadly consistent with Bayesian and Relevance-based approaches to category-based inductive reasoning, neither approach captures all of our findings.     

Alternative antecedents, probabilities, and the suppression of fallacies in Wason's selection task

Three experiments examined the influence of a second rule on the pattern of card selections on Wason's selection task. In Experiment 1 participants received a version of the task with a single test rule or one of two versions of the task with the same original test rule together with a second rule. The probability of q was manipulated in the two-rules conditions by varying the size of the antecedent set in the second rule. The results showed a significant suppression of q card and not-p card selections in the alternative-rule conditions, but no difference as a function of antecedent set size. In Experiment 2 the size of the antecendent set in the two-rules conditions was manipulated using the context of a computer printing double-sided cards. The results showed a significant reduction of q card selections in the two-rules conditions, but no effect of p set size. In Experiment 3 the scenario accompanying the rule was manipulated, and it specified a single alternative antecedent or a number of alternative antecedents. The q card selection rates were not affected by the scenario manipulation but again were suppressed by the presence of a second rule. Our results suggest that people make inferences about the unseen side of the cards when engaging with the task and that these inferences are systematically influenced by the presence of a second rule, but are not influenced by the probabilistic characteristics of this rule. These findings are discussed in the context of decision theoretic views of selection task performance (Oaksford & Chater, 1994).     

Regret as autobiographical memory

We apply an autobiographical memory framework to the study of regret. Focusing on the distinction between regrets for specific and general events we argue that the temporal profile of regret, usually explained in terms of the action–inaction distinction, is predicted by models of autobiographical memory. In two studies involving participants in their sixties we demonstrate a reminiscence bump for general, but not for specific regrets. Recent regrets were more likely to be specific than general in nature. Coding regrets as actions/inactions revealed that general regrets were significantly more likely to be due to inaction while specific regrets were as likely to be due to action as to inaction. In Study 2 we also generalised all of these findings to a group of participants in their 40s. We re-interpret existing accounts of the temporal profile of regret within the autobiographical memory framework, and outline the practical and theoretical advantages of our memory-based distinction over traditional decision-making approaches to the study of regret.     

Attachment insecurity,depression, and the transition to parenthood

In a longitudinal study of adult attachment and depression during the transition to parenthood, 76 couples completed questionnaires on three occasions: during the second trimester of pregnancy, and six weeks and six months postbirth. On the first and second occasions, the couples were also interviewed about their experiences of pregnancy and parenthood, respectively. Measures were also completed at similar time intervals by a comparison group of 74 childless couples. Attachment security was assessed in terms of the dimensions of discomfort with closeness and relationship anxiety. Relationship anxiety was less stable for transition wives than for other participants. Relationship anxiety also predicted increases in new mothers’ depressive symptoms, after controlling for a broad range of other risk factors. However, the association between relationship anxiety and maternal depression was moderated by husbands’ caregiving style. Maternal depression was linked to increases in husbands’ and wives’ attachment insecurity and marital dissatisfaction. Results are discussed in terms of the impact of depression and negative working models of attachment on couple interaction.     

Measuring romantic jealousy: Validation of the multidimensional jealousy scale in Australian samples

Although a number of questionnaires have been developed to measure romantic jealousy, there is a lack of independent research that has substantiated their psychometric properties and minimal research that has tested and applied these measures in a consistent and reliable way. We aimed to address these gaps by providing the first validation study of an existing measure of romantic jealousy—the Multidimensional Jealousy Scale (MJS). The MJS was subjected to exploratory and confirmatory factor analyses in two separate samples of individuals in romantic relationships of at least 2 months duration. A 17‐item Short‐Form MJS (SF‐MJS) was supported, with three factors representing cognitive, emotional, and behavioural jealousy. Internal reliabilities were high. Consistent evidence supported the discriminant and concurrent validity of the SF‐MJS. Overall, the current research provides a brief, validated measure of romantic jealousy for use in the general population. Potential clinical uses are discussed.     

Knowing when to hold ‘em: regret and the relation between missed opportunities and risk taking in children,adolescents and adults

Regret over missed opportunities leads adults to take more risks. Given recent evidence that the ability to experience regret impacts decisions made by 6-year-olds, and pronounced interest in the antecedents to risk taking in adolescence, we investigated the age at which a relationship between missed opportunities and risky decision-making emerges, and whether that relationship changes at different points in development. Six- and 8-year-olds, adolescents and adults completed a sequential risky decision-making task on which information about missed opportunities was available. Children also completed a task designed to measure their ability to report regret when explicitly prompted to do so. The relationship between missed opportunities and risky decision-making did not emerge until 8 years, at which age it was associated with the ability to explicitly report regret, and was stronger in adults than in adolescents. These novel results highlight the potential importance of the ability to experience regret in children and adolescents’ risky decision-making.     

A longitudinal investigation of relational catalyst support of goal strivings

The goal of this work was to test a theoretical model of relational catalyst (RC) support provision that promotes thriving in non-adverse times. We tested a pathway proposed by Feeney and Collins that explains how RC support in the context of close relationships might lead to thriving. We proposed that once RC support has been received, it functions through the mechanisms of being perceived to be responsive to one’s needs and promoting perceived capability. Perceived capability should promote indices of thriving including self-esteem, goal accomplishment, growth, and specific and general availability of support. This model was supported in two studies of married couples using observational and longitudinal methods surrounding the support of goal strivings. Results indicate that (a) partner support of goal strivings predicted important indicators of thriving over time, and (b) both received and perceived RC support work together and play important roles in predicting these outcomes.     

Predictors of caregiving in adult intimate relationships: an attachment theoretical perspective.

Romantic couples (N = 194) participated in an investigation of caregiving processes in adulthood. In Phase 1, couple members completed questionnaires designed to identify attachment style differences in caregiving behavior and to explore the underlying (personal and relationship) mechanisms that lead people with different attachment styles to be effective or ineffective caregivers. Results revealed that social support knowledge, prosocial orientation. interdependence, trust, and egoistic motivation mediated the link between attachment style and caregiving. In Phase 2, responsive caregiving was assessed behaviorally by exposing one member of the couple to a stressful laboratory situation and experimentally manipulating his or her need for support. Results revealed that attachment style and mediating mechanisms identified in Phase 1 also predicted observable support behavior in a specific episode in which a partner had a clear need for support.     

The dependency paradox in close relationships: accepting dependence promotes independence

Using multiple methods, this investigation tested the hypothesis that a close relationship partner's acceptance of dependence when needed (e.g., sensitive responsiveness to distress cues) is associated with less dependence, more autonomous functioning, and more self-sufficiency (as opposed to more dependence) on the part of the supported individual. In two studies, measures of acceptance of dependency needs and independent functioning were obtained through couple member reports, by observing couple members' behaviors during laboratory interactions, by observing responses to experimentally manipulated partner assistance provided during an individual laboratory task, and by following couples over a period of 6 months to examine independent goal striving as a function of prior assessments of dependency acceptance. Results provided converging evidence in support of the proposed hypothesis. Implications of the importance of close relationships for optimal individual functioning are discussed.     

The relationship between counterfactual thinking and emotional reactions to event outcomes: Does one account fit all?

By enabling a comparison between what is and what might have been, counterfactual thoughts amplify our emotional responses to bad outcomes. Well-known demonstrations such as the action effect (the tendency to attribute most regret to a character whose actions brought about a bad outcome) and the temporal order effect (the tendency to undo the last in a series of events leading up to a bad outcome) are often explained in this way. An important difference between these effects is that outcomes are due to decisions in the action effect, whereas in the temporal order effect outcomes are achieved by chance. In Experiment 1, we showed that imposing time pressure leads to a significant reduction in the action but not in the temporal order effect. In Experiment 2, we found that asking participants to evaluate the protagonists (“who ought to feel worse?”) led to a significant reduction in the temporal order but not in the action effect. The results suggest that the action and temporal order effects require different explanations and are consistent with other work that suggests that when decisions lead to bad outcomes a comparison of decision quality is an important determinant of the emotional response attributed to the protagonists.
