Aha! experiences leave a mark: facilitated recall of insight solutions

The present study investigates a possible memory advantage for solutions that were reached through insightful problem solving. We hypothesized that insight solutions (with Aha! experience) would be remembered better than noninsight solutions (without Aha! experience). 34 video clips of magic tricks were presented to 50 participants as a novel problem-solving task, asking them to find out how the trick was achieved. Upon discovering the solution, participants had to indicate whether they had experienced insight during the solving process. After a delay of 14 days, a recall of solutions was conducted. Overall, 55 % of previously solved tricks were recalled correctly. Comparing insight and noninsight solutions, 64.4 % of all insight solutions were recalled correctly, whereas only 52.4 % of all noninsight solutions were recalled correctly. We interpret this finding as a facilitating effect of previous insight experiences on the recall of solutions.     

Intentional and Non-Intentional Assessments of Emotion Experiences: Comparisons of Old and New Measures

In two studies, we compared intentional and non-intentional measures of emotional well-being in terms of reliability and validity. In the first study, we expanded on the findings of ?im?ek (2011 ?im?ek, Ö. F. (2011). An Intentional Model of Emotional Well-Being: The Development and Initial Validation of a Measure of Subjective Well-Being. Journal of Happiness Studies, 12, 421–442. [Google Scholar]) by showing that an intentional measure of emotional well-being, namely the Emotional Well-Being Scale, accounted for unique variance in both negative and positive mental health indicators above and beyond the variance accounted for by Larsen and Diener's Scales (1992), which measures all dimensions of affect circumplex. The correlated traits-correlated uniqueness model results showed that the original-intentional version of the Emotional Well-Being Scale explained more variance in the measurement model than the non-intentional version. The second study showed that the results were similar for the intentional vs. non-intentional versions of the Positive and Negative Affect Schedules (Watson, Clark &; Tellegen, 1988 Watson, D., Clark, L. A., &; Tellegen, A. (1988). Development and validation of brief measures of positive and negative affect: The PANAS scales. Journal of Personality and Social Psychology, 54, 1063–1070. [Google Scholar]). The intentional version of the Positive and Negative Affect Schedules accounted for more variance in the criteria than the non-intentional version.     

The Effect of Temporal Distance on Attitudes toward Imprecise Probabilities and Imprecise Outcomes

Many personal, managerial, and societal decisions involve uncertain or ambiguous consequences that will occur in the future. Yet, previous empirical research on ambiguity preferences has focused mainly on decisions with immediate outcomes. To close this gap in the literature, this paper examines ambiguity attitudes toward future prospects, particularly how they may differ from the attitudes toward comparable prospects in the present. On the basis of a recent paradigm, we first distinguish between two types of ambiguity: imprecise probabilities and imprecise outcomes. Then, in accordance with construal level theory, which shows that temporal distance increases the relative importance of outcomes over probabilities in evaluating prospects, we conjecture that temporal distance would moderate attitudes toward imprecise probabilities but amplify attitudes toward imprecise outcomes. Through a series of experiments, we demonstrate that when the prospects are in the future, individuals are less averse toward imprecise probabilities and more seeking toward imprecise outcomes. However, the effect is most prominent for prospects where both the probability and outcome dimensions are concurrently imprecise. The paper ends with a discussion on how dimension salience may have contributed to this result. Copyright © 2012 John Wiley & Sons, Ltd.     

The interference problem for the betting interpretation of degrees of belief

The paper’s target is the historically influential betting interpretation of subjective probabilities due to Ramsey and de Finetti. While there are several classical and well-known objections to this interpretation, the paper focuses on just one fundamental problem: There is a sense in which degrees of belief cannot be interpreted as betting rates. The reasons differ in different cases, but there’s one crucial feature that all these cases have in common: The agent’s degree of belief in a proposition A does not coincide with her degree of belief in a conditional that A would be the case if she were to bet on A, where the belief in this conditional itself is conditioned on the supposition that the agent will have an opportunity to make such a bet. Even though the two degrees of belief sometimes can coincide (they will coincide in those cases when the bet has no expected causal bearings on the proposition A and the opportunity to bet have no evidential bearings on that proposition), it is the latter belief rather than the former that guides the agent’s rational betting behaviour. The reason is that this latter belief takes into consideration potential interferences that bet opportunities and betting itself might create with regard to the proposition to be betted on. It is because of this interference problem that the agent’s degree of belief in A cannot be interpreted as her betting rate for A.     

An Evaluation of Equivalence in Body Dissatisfaction Measurement Across Cultures

We evaluated gender-based and cross-cultural equivalence of the Body Dissatisfaction Scale of the Body Change Inventory in a sample of 4,005 adolescents from 7 cultures that represent diverse body image ideals and response styles. Results of multigroup confirmatory factor analyses demonstrated equivalence of the scale across gender but not across cultures. Follow-up analyses identified small but significant cross-cultural differences in response styles (specifically, acquiescence and middle response option endorsement) as the source of this noninvariance. We recommend use of this scale for gender-based comparisons but caution that researchers should evaluate the presence of response biases before making substantive conclusions about cross-cultural differences in body dissatisfaction.     

Assessment of Personality Organization in Couple Relationships: Factorial Structure of the Inventory of Personality Organization and Incremental Validity Over Neuroticism

Summary: Creative thinking was explored from several approaches to further understanding of the interrelationship of perception, personality, and cognition. College students (N = 45) were administered the Group Embedded Figures Test (GEFT), the Remote Associates Test (RAT), a questionnaire concerning RAT strategy, and two self-report scales. Field independent subjects were found to be significantly (p < .001) more creative than field dependents. Correlations between the RAT and GEFT and the self-report measures of conformity and creativity, while largely nonsignificant, were in the predicted directions. Results demonstrated that advanced strategy levels and insightful responses were significantly related to high performance on the RAT. Theoretical links between cognitive style and Piagetian concepts were discussed in regard to creative thought. Overall, these findings support the contention that the creative processes should be studied, not as isolated structures, but with relational and multifaceted emphasis.     

The efficacy of massage on short and long term outcomes in preterm infants

Purpose

Premature infants lack the tactile stimulation they would have otherwise experienced in the womb. Infant massage is a developmentally supportive intervention that has been documented for several decades to have a positive effect on both full term and preterm infants. The purpose of this study was to assess the short and long term benefits of massage on stable preterm infants.

Methods

A quasi experimental design was used, 66 infants were recruited from two university hospitals with tertiary level NICUs; 32 infants received the massage therapy by their mothers. Data collection by a researcher blind to the infants’ group assignments included weight at discharge, pain responses on the PIPP scale at discharge, length of stay in hospital, neuro-developmental outcome (Bayley scores) and breastfeeding duration at 12 months corrected age.

Results

Infants who were massaged had significantly lower scores on the PIPP after a heel-stick compared to before the massage and had lower PIPP scores at discharge compared to the control group. Massaged infants had higher cognitive scores at 12 months corrected age. Weight gain, length of stay, breastfeeding duration and motor scores did not differ between groups.

Conclusion

Stable preterm infants benefit from massage therapy given by their mothers and may be a culturally acceptable form of intervention to improve the outcomes of preterm infants.     

The neural basis of updating: Distinguishing substitution processes from other concurrent processes

Sörqvist, P. & Sætrevik, B. (2010). The neural basis of updating: Distinguishing substitution processes from other concurrent processes. Scandinavian Journal of Psychology, 51, 357–362. Most previous studies of updating processes have not been able to contrast processes of substituting items in memory with other concurrent processes. In the present investigation, we used a new task called “number updating” and an fMRI protocol to contrast the activation of trials that require item substitution (adding a new item to the working memory representation and suppressing an old item) with trials that involve no substitution (discarding the new item). Trials that require item substitution activated the dorsolateral prefrontal cortex, the posterior medial frontal cortex and the parietal lobes, areas typically seen activated for working memory tasks in general. Trials that do not require substitution activated the anterior medial frontal cortex. Studies examining executive functions have associated this area with cognitive conflict, and may represent suppression of the substitution processes.     

Professional and non-professional drivers’ stress reactions and risky driving

The aim of the present study was to investigate stress reactions, speeding, number of penalties and accident involvement among different driver groups (taxi drivers, minibus drivers, heavy vehicle drivers, and non-professional drivers). A total number of 234 male drivers participated in the study. The participants were asked to complete the Driver Stress Inventory (DSI) together with a demographic information form. Five dimensions of the DSI were measured; aggression, dislike of driving, hazard monitoring, fatigue proneness, and thrill-seeking. After controlling the effects of age and annual mileage, the results of the ANCOVAs revealed differences between different driver groups in terms of both risky driving behaviours and stress reactions in traffic. Regression analyses indicated that aggression, dislike of driving, and hazard monitoring dimensions of the DSI were related to accident involvement after controlling for the effects of age, annual mileage and driver group. Dislike of driving and thrill-seeking dimensions of the DSI were related to speeding on in-city roads.
