Traumatic Exposure and Psychological Well-Being: The Moderating Role of Cognitive Flexibility

This study examined the moderating role of cognitive flexibility between earthquake exposure and psychological well-being. The participants were 491 adolescents from three middle schools in Sichuan. Multivariable, hierarchical linear regressions were used to analyze the data. The findings showed that there were significant differences in psychological well-being for the dimension of relocation of school (T = ?3.09, p < 0.01), damage to property (F = 2.73, p < 0.05) and damage to school (F = 5.76, p < 0.01). Hierarchical regression analysis indicated that cognitive flexibility moderated the relation between being hurt during the earthquake and psychological well-being (B = 1.01, SE = 0.31, T = 3.22, p < 0.01).     

(Re)evaluating the Implications of the Autoregressive Latent Trajectory Model Through Likelihood Ratio Tests of Its Initial Conditions

The autoregressive latent trajectory (ALT) model synthesizes the autoregressive model and the latent growth curve model. The ALT model is flexible enough to produce a variety of discrepant model-implied change trajectories. While some researchers consider this a virtue, others have cautioned that this may confound interpretations of the model's parameters. In this article, we show that some—but not all—of these interpretational difficulties may be clarified mathematically and tested explicitly via likelihood ratio tests (LRTs) imposed on the initial conditions of the model. We show analytically the nested relations among three variants of the ALT model and the constraints needed to establish equivalences. A Monte Carlo simulation study indicated that LRTs, particularly when used in combination with information criterion measures, can allow researchers to test targeted hypotheses about the functional forms of the change process under study. We further demonstrate when and how such tests may justifiably be used to facilitate our understanding of the underlying process of change using a subsample (N = 3,995) of longitudinal family income data from the National Longitudinal Survey of Youth.     

Home environmental influences on children's language and reading skills in a genetically sensitive design: Are socioeconomic status and home literacy environment environmental mediators and moderators?

This twin study examined how family socioeconomic status (SES) and home literacy environment (HLE) contributes to Chinese language and reading skills. It included 312 Chinese twin pairs aged 3 to 11. Children were individually administered tasks of Chinese word reading, receptive vocabulary and reading‐related cognitive skills, and nonverbal reasoning ability. Information on home environment was collected through parent‐reported questionnaires. Results showed that SES and HLE mediated shared environmental influences but did not moderate genetic influences on general language and reading abilities. Also, SES and HLE mediated shared environmental contributions to receptive vocabulary and syllable and rhyme awareness, but not orthographic skills. The findings of this study add to past twin studies that focused on alphabetic languages, suggesting that these links could be universal across languages. They also extend existing findings on SES and HLE's contributions to reading‐related cognitive skills.     

Perception of Native English Reduced Forms in Adverse Environments by Chinese Undergraduate Students

Previous research has shown that learners of English-as-a-second-language (ESL) have difficulties in understanding connected speech spoken by native English speakers. Extending from past research limited to quiet listening condition, this study examined the perception of English connected speech presented under five adverse conditions, namely multi-talker babble noise, speech-shaped noise, factory noise, whispering and sad emotional tones. We tested a total of 64 Chinese ESL undergraduate students, using a battery of listening tasks. Results confirmed that the recognition of English native speech was more challenging for Chinese ESL learners under unfavorable listening conditions, in comparison to a noise-free listening condition. These findings carry significant implications for the importance of training and assessments on connected speech perception across various listening environments.     

Predicting the psychological health of older adults: Interaction of age-based rejection sensitivity and discriminative facility

We hypothesize that older adults who anxiously expect, readily perceive, and intensely react to social rejection because of their old age (i.e., have high age-based rejection sensitivity) are vulnerable to depression and poor social functioning. We further hypothesize that the association between age-based rejection sensitivity and poor psychological health would be attenuated among older adults who possess adequate cognitive coping ability—they can discern and respond discriminatively to subtle variations in situational demands (i.e., have high discriminative facility). Based on the results of a focus group study, we constructed an age-based rejection sensitivity measure, which predicts greater depression, poorer social functioning, greater loneliness, and lower life satisfaction among individuals in late adulthood. As hypothesized, the relationship between age-based rejection sensitivity and poor psychological health was weaker among older adults with high (vs. low) discriminative facility.     

Dialogic reading and morphology training in Chinese children: effects on language and literacy

This study investigates the effects of parent-child shared book reading and metalinguistic training on the language and literacy skills of 148 kindergartners in Hong Kong. Children were pretested on Chinese character recognition, vocabulary, morphological awareness, and reading interest and then assigned randomly to 1 of 4 conditions: the dialogic reading with morphology training (DR + MT), dialogic reading (DR), typical reading, or control condition. After a 12-week intervention period, the DR intervention yielded greater gains in vocabulary, and the DR + MT intervention yielded greater improvement in character recognition and morphological awareness. Both interventions enhanced children's reading interest. Results confirm that different home literacy approaches influence children's oral and written language skills differently: Shared book reading promotes language development, whereas parents' explicit metalinguistic training within a shared book reading context better prepares children for learning to read.     

The two faces of dominance: The differential effect of ingroup superiority and outgroup inferiority on dominant-group identity and group esteem

The present paper provides evidence that dominant-group members distinguish dominance framed as ingroup superiority from dominance framed as outgroup inferiority, and that ingroup superiority enhances esteem for, and thus identification with, the group more than outgroup inferiority. In Experiment 1, Democrats report higher levels of party identification after being told that Democrats won an election than after being told that Republicans lost the election. These effects are attenuated among dominant group members whose values are in conflict with how dominance was achieved. In Experiments 2a and 2b, unearned dominance framed as ingroup superiority resulted in higher levels of White identification than unearned dominance framed as outgroup inferiority among Whites who did not value meritocracy. In contrast, Whites who valued meritocracy did not increase their levels of identification with the group. In Experiment 2b, this interactive effect on racial identification was mediated by esteem for the group.     

To see or not to see: infants prefer to follow the gaze of a reliable looker

In two experiments, we examined whether 14‐month‐olds understand the subjective nature of gaze. In the first experiment, infants first observed an experimenter express happiness as she looked inside a container that either contained a toy (reliable looker condition) or was empty (unreliable looker condition). Then, infants had to follow the same experimenter's gaze to a target object located either behind or in front of a barrier. Infants in the reliable looker condition followed the experimenter's gaze behind the barrier more often than infants in the unreliable looker condition, whereas both groups followed the experimenter's gaze to the target object located in front of the barrier equally often. In the second experiment, infants did not generalize their knowledge about the unreliability of a looker to a second ‘naïve’ looker. These findings suggest that 14‐month‐old infants adapt their gaze following as a function of their past experience with the looker.     

Variation in coordination of a discrete multiarticular action as a function of skill level

The authors investigated coordination modes that emerged as a function of the interaction between skill level and task constraints in a multiarticular kicking action. Five skilled, 5 intermediate, and 5 novice participants attempted to satisfy specific height and accuracy constraints in kicking a ball over a barrier. Skilled and intermediate groups demonstrated a functional coordination mode involving less joint involvement at the proximal joints and greater joint involvement at distal joints, mimicking a chip-like action in soccer. Conversely, the novice group tended to produce larger ranges of motion throughout the kicking limb in a driving-like kicking action. Key differences were also found for task outcome scores, joint angle-angle relations, and ball-trajectory plots between the skilled and intermediate groups and the novice group. Findings from this study demonstrated that joint involvement during this discrete multiarticular action is a function of skill level and task constraints rather than a consequence of a global freezing-freeing strategy suggested in some previous research. The authors also highlight the merit of using a model of the acquisition of coordination in examining how coordination modes for multiarticular actions differ as a function of skill.     

Age and culture modulate object processing and object—scene binding in the ventral visual area

Behavioral differences in the visual processing of objects and backgrounds as a function of cultural group are well documented. Recent neuroimaging evidence also points to cultural differences in neural activation patterns. Compared with East Asians, Westerners’ visual processing is more object focused, and they activate neural structures that reflect this bias for objects. In a recent adaptation study, East Asian older adults showed an absence of an object-processing area but normal adaptation for background areas. In the present study, 75 young and old adults (half East Asian and half Western) were tested in an fMR-adaptation study to examine differences in object and background processing as well as object—background binding. We found equivalent background processing in the parahippocampal gyrus in all four groups, diminished binding processes in the hippocampus in elderly East Asians and Westerners, and diminished object processing in elderly versus young adults in the lateral occipital complex. Moreover, elderly East Asians showed significantly less adaptation response in the object areas than did elderly Westerners. These findings demonstrate the malleability of perceptual processes as a result of differences in cohort-specific experiences or in cultural exposure over time.
