Pubertal development shapes perception of complex facial expressions

We previously hypothesized that pubertal development shapes the emergence of new components of face processing (Scherf et al., 2012; Garcia & Scherf, 2015). Here, we evaluate this hypothesis by investigating emerging perceptual sensitivity to complex versus basic facial expressions across pubertal development. We tested pre‐pubescent children (6–8 years), age‐ and sex‐matched adolescents in early and later stages of pubertal development (11–14 years), and sexually mature adults (18–24 years). Using a perceptual staircase procedure, participants made visual discriminations of both socially complex expressions (sexual interest, contempt) that are arguably relevant to emerging peer‐oriented relationships of adolescence, and basic (happy, anger) expressions that are important even in early infancy. Only sensitivity to detect complex expressions improved as a function of pubertal development. The ability to perceive these expressions is adult‐like by late puberty when adolescents become sexually mature. This pattern of results provides the first evidence that pubertal development specifically influences emerging affective components of face perception in adolescence.     

Emotion,gender, and gender typical identity in autobiographical memory

Gender differences in the emotional intensity and content of autobiographical memory (AM) are inconsistent across studies, and may be influenced as much by gender identity as by categorical gender. To explore this question, data were collected from 196 participants (age 18–40), split evenly between men and women. Participants narrated four memories, a neutral event, high point event, low point event, and self-defining memory, completed ratings of emotional intensity for each event, and completed four measures of gender typical identity. For self-reported emotional intensity, gender differences in AM were mediated by identification with stereotypical feminine gender norms. For narrative use of affect terms, both gender and gender typical identity predicted affective expression. The results confirm contextual models of gender identity (e.g., Diamond, 2012 Diamond, L. M. (2012). The desire disorder in research on sexual orientation in women: Contributions of dynamical systems theory. Archives of Sexual Behavior, 41, 73–83. doi: 10.1007/s10508-012-9909-7[Crossref], [PubMed], [Web of Science ®] , [Google Scholar].

The effect of motion at encoding and retrieval for same- and other-race face recognition

In an experimental study, we assessed the role of motion when encoding and recognizing unfamiliar faces, using an old/new recognition memory paradigm. Our findings revealed a clear advantage for learning unfamiliar faces moving non-rigidly, compared with static faces. This advantage for motion was found with both same- and other-race faces. Furthermore, results indicate that it is more important that the face is learnt in motion than recognized from a moving clip. Interestingly, despite a reliable other-race effect being revealed, participants were able to utilize motion information exhibited by other-race faces in a manner akin to the motion advantage found for same-race faces. The implications of these findings are discussed in relation to the nature of the stored face representations, considering whether the facilitative role found here can be explained by factors other than motion per se.     

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.     

The Presence of Self-Stigma,Perceived Stress,and Suicidal Ideation among Selected LGBT Filipinos

Minority group members experience what is known as “minority stress,” by which individuals suffer stress because of their membership in stigmatized social categories. In turn, minority stress may lead to self-stigmatization. This occurs when minority group members experience a sense of shame created by the view of the majority culture and then incorporate the majority opinion into their self-image. Because it is cumulative with the stress an individual is already experiencing, self-stigmatization may become a significant stressor itself, possibly contributing to the development of suicidal ideation. A total of 609 self-identified LGBT individuals were asked to answer a battery of psychological tests to assess the interrelationships between self-stigma, perceived stress, and suicidal ideation. As expected, perceived stress predicted suicidal ideation, whereas self-stigmatization predicted both perceived stress and suicidal ideation. Structural equation modeling confirms the predictive value of self-stigma together with perceived stress in determining the suicidal ideation present among LGBT Filipinos. Self-stigma exerted a direct effect upon suicidal ideation not accounted for by perceived stress.     

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.
