Trajectory of risky decision making for potential gains and losses from ages 5 to 85

The ability to make advantageous decisions in the face of uncertainty is an essential human skill, yet the development of such abilities over the lifespan is still not well understood. In the current study, from childhood through older adulthood, we tracked the developmental trajectory of risk taking for gains and losses, and expected value (EV) sensitivity in risky choices. In the gain domain, risk‐taking decreased consistently across the lifespan. In the loss domain, risk‐taking was relatively constant across ages, a result we attribute to the pervasiveness of loss aversion. EV sensitivity showed an inverted‐U‐shaped function, increasing from childhood to adulthood but then decreasing for the elderly, which occurred for both risky gains and risky losses. This finding is consistent with neuropsychological and neuroanatomical evidence concerning the role of the frontal lobe in decision making, which is relatively late to develop during childhood but may degrade earlier in the later years.

A bad taste in the mouth: gustatory disgust influences moral judgment

Can sweet-tasting substances trigger kind, favorable judgments about other people? What about substances that are disgusting and bitter? Various studies have linked physical disgust to moral disgust, but despite the rich and sometimes striking findings these studies have yielded, no research has explored morality in conjunction with taste, which can vary greatly and may differentially affect cognition. The research reported here tested the effects of taste perception on moral judgments. After consuming a sweet beverage, a bitter beverage, or water, participants rated a variety of moral transgressions. Results showed that taste perception significantly affected moral judgments, such that physical disgust (induced via a bitter taste) elicited feelings of moral disgust. Further, this effect was more pronounced in participants with politically conservative views than in participants with politically liberal views. Taken together, these differential findings suggest that embodied gustatory experiences may affect moral processing more than previously thought.     

A Comparison of Population-Averaged and Cluster-Specific Approaches in the Context of Unequal Probabilities of Selection

Sampling designs of large-scale survey studies are typically complex, involving multiple design features such as clustering and unequal probabilities of selection. Single-level (i.e., population-averaged) methods that use adjusted variance estimators and multilevel (i.e., cluster-specific) methods provide two alternatives for modeling clustered data. Although the literature comparing these methods is vast, comparisons have been limited to the context in which all sampling units are selected with equal probabilities (thus circumventing the need for sampling weights). The goal of this study was to determine under what conditions single-level and multilevel estimators outperform one another in the context of a two-stage sampling design with unequal probabilities of selection. Monte Carlo simulation methods were used to evaluate the impact of several factors, including population model, informativeness of the design, distribution of the outcome variable, intraclass correlation coefficient, cluster size, and estimation method. Results indicated that the unweighted estimators performed similarly across conditions, whereas the weighted single-level estimators tended to outperform the weighted multilevel estimators, particularly under nonideal sample conditions. Multilevel weight approximation methods did not perform well when the design was informative. An empirical example is provided to demonstrate how researchers might investigate the implications of the simulation results in practice.     

Idiom Comprehension in Mandarin-Speaking Children

This study examines the effect of familiarity, context, and linguistic convention on idiom comprehension in Mandarin speaking children. Two experiments (a comprehension task followed by a comprehension task coupled with a metapragmatic task) were administered to test participants in three age groups (6 and 9-year-olds, and an adult control group). Laval (Journal of Pragmatics 35(2):723–739, 2003) showed that familiarity had an effect on idiom comprehension for French 9-year-olds. However, our finding showed that familiarity was important for 6-year-old Chinese children when a context was not given. Abkarian et al. (Journal of Speech and Hearing Research 35:580–587, 1992) claimed that context has little or no effect on comprehension for children under 6. Our results show that context has an effect on 6-year-old children’s understanding of idioms in a different way. Overall, our major research findings are: (1) Familiarity first appeared in responses at age 6. (2) Context played an important role in idiom comprehension and had different effects on different age groups. (3) Linguistic convention starts from age 6 on, and a significant effect took place at the age of 9. (4) Metapragmatic knowledge showed at the age of 6 and could surface even younger. As context and linguistic convention have a substantial effect on the comprehension of idioms, it is necessary to take them into account to explain language functioning and communicative situations.     

Providing Practicing Teachers Classroom Management Professional Development in a Brief Self-Study Format

This study examined the impact of a time efficient self-study method for providing practicing teachers with job-embedded professional development targeting specific classroom management skills. The training method employed print packets and videotapes that provided models of effective classroom management strategies for instruction-giving, praise, and time out. Participants were three master’s level speech therapists certified to teach speech and language delayed preschool children. The training materials were evaluated through observations of the teachers’ implementation of targeted practices in a multiple baseline across participants. Results indicated increases in all participants use of the management skills after training. The results suggest that this type of training method may help teachers increase their use of effective classroom management procedures. It is potentially noteworthy that the training program examined herein was largely teacher managed and was quite brief. Future directions and limitations of the study are discussed.Natalie J. Slider is now at Brownsburg Community School Corporation.     

Worried and wired: effects of health anxiety on information-seeking and health care utilization behaviors.

Although online health information-seeking has been widely studied and findings suggest a variety of motivations behind an individual's health information-seeking behavior, little is known about how this information influences health utilization behaviors. Thus, the current study investigates the relationship between online health information seeking and health care utilization such as visiting a doctor. Additionally, this project expands the literature by examining the moderating role of health anxiety. Results suggest that an individual's level of health anxiety moderates the relationship between online health information seeking and health care utilization decisions.     

The Social Nature of Perception and Action

ABSTRACT— Humans engage in a wide range of social activities. Previous research has focused on the role of higher cognitive functions, such as mentalizing (the ability to infer others' mental states) and language processing, in social exchange. This article reviews recent studies on action perception and joint action suggesting that basic perception–action links are crucial for many social interactions. Mapping perceived actions to one's own action repertoire enables direct understanding of others' actions and supports action identification. Joint action relies on shared action representations and involves modeling of others' performance in relation to one's own. Taking the social nature of perception and action seriously not only contributes to the understanding of dedicated social processes but has the potential to create a new perspective on the individual mind and brain.     

DO FEMINIST IDENTITY STYLES MODERATE THE RELATION BETWEEN PERCEIVED SEXIST EVENTS AND DISORDERED EATING?

Feminist consciousness is theorized to be a powerful resource against the detrimental effects of sexism. The present study examined whether feminist identity styles moderated the relation of perceived lifetime and recent sexist events to disordered eating for 256 college women. Using hierarchical moderated regression, we found two styles of feminist identity (i.e., synthesis and active commitment) buffered the relation between perceived sexist events and disordered eating; the three remaining styles of feminist identity did not moderate this relationship. For women low on synthesis and active commitment, both perceived lifetime and recent sexist events positively predicted disordered eating. In contrast, for women high on synthesis and active commitment, neither perceived lifetime nor recent sexist events predicted disordered eating. Our results substantiate extant theory that sexist events contribute more to the psychological distress of nonfeminist women than of feminist women.     

Sexual well-being and perceived stress in couples transitioning to parenthood: A dyadic analysis

Background/ObjectiveThe transition to parenthood encompasses several psychological and relational changes that might contribute to couples’ high levels of stress postpartum. Although common across the postpartum, couples’ sexual changes are frequently overlooked.MethodWe surveyed 255 mixed-sex new parent couples to examine the associations between sexual well-being—sexual satisfaction, desire, and postpartum sexual concerns—and perceived stress postpartum. Couples completed self-report questionnaires assessing perceived stress and sexual well-being.ResultsFor both mothers and fathers, greater sexual satisfaction was associated with their partners’ lower perceived stress and, for fathers, this was also associated with their own lower perceived stress. For mothers, greater partner-focused sexual desire was associated with their own lower perceived stress whereas, for fathers, greater partner-focused sexual desire was associated with their partners’ higher perceived stress. In addition, greater solitary sexual desire and postpartum sexual concerns were associated with both parents’ own higher perceived stress.ConclusionsThis study highlights the association between sexual well-being and couples’ postpartum stress, suggesting that more positive sexual experiences are linked to lower perceptions of stress across this vulnerable period. Couples’ sexual well-being may be an important target for interventions aimed at helping postpartum couples cope with stress.
