This study addresses the question of how age of acquisition (AoA) affects grammatical processing, specifically with respect to inflectional morphology, in bilinguals. We examined experimental data of more than 100 participants from the Russian/German community in Berlin, all of whom acquired Russian from birth and German at different ages. Using the cross-modal lexical priming technique, we investigated stem allomorphs of German verbs that encode multiple morphosyntactic features. The results revealed a striking AoA modulation of observed priming patterns, indicating efficient access to morphosyntactic features for early AoAs and a gradual decline with increasing AoAs. In addition, we found a discontinuity in the function relating AoA to morphosyntactic feature access, suggesting a sensitive period for the development of morphosyntax.
Previous cross-modal priming studies showed that lexical decisions to words after a pronoun were facilitated when these words were semantically related to the pronoun’s antecedent. These studies suggested that semantic priming effectively measured antecedent retrieval during coreference. We examined whether these effects extended to implicit reading comprehension using the N400 response. The results of three experiments did not yield strong evidence of semantic facilitation due to coreference. Further, the comparison with two additional experiments showed that N400 facilitation effects were reduced in sentences (vs. word pair paradigms) and were modulated by the case morphology of the prime word. We propose that priming effects in cross-modal experiments may have resulted from task-related strategies. More generally, the impact of sentence context and morphological information on priming effects suggests that they may depend on the extent to which the upcoming input is predicted, rather than automatic spreading activation between semantically related words.
Previous research offers equivocal results regarding the effect of
social networking site use on individuals’ self-esteem. We con-
duct a systematic literature review to examine the existing litera-
ture and develop a theoretical framework in order to classify the
results. The framework proposes that self-esteem is affected by
three distinct processes that incorporate self-evaluative informa-
tion: social comparison processes, social feedback processing,
and self-reflective processes. Due to particularities of the social
networking site environment, the accessibility and quality of self-
evaluative information is altered, which leads to online-specific
effects on users’ self-esteem. Results of the reviewed studies
suggest that when a social networking site is used to compare
oneself with others, it mostly results in decreases in users’ self-
esteem. On the other hand, receiving positive social feedback
from others or using these platforms to reflect on one’s own self is
mainly associated with benefits for users’ self-esteem.
Nevertheless, inter-individual differences and the specific activ-
ities performed by users on these platforms should be considered
when predicting individual effects.
There is controversy in the literature in regards of the link between training load and injury rate. Thus, the aims of this non-interventional study were to evaluate relationships between pre-season training load with biochemical markers, injury incidence and performance during the first month of the competitive period in professional soccer players.

Multiple health behaviour change (MHBC) represents one of the best ways to prevent reoccurrence of cardiovascular events. However, few
individuals with cardiovascular diseases engage in this process. The
present study examined the role of compensatory health beliefs (CHB;
i.e., belief that a healthy behaviour compensates an unhealthy one)as
a drag to engagement in this process. Some studies have shown that
CHBs predict intention to engage in healthy behaviours, but no study
has investigated CHBs in individuals who actually need to change
multiple health behaviours. The goal was to better understand the
role of CHBs in intentions formation process among individuals with
cardiac diseases in an MHBC context. One hundred and four patients
completed a questionnaire at the beginning of their cardiac rehabilitation program. Results showed that: (1) CHBs negatively predicted intentions (2) but only for participants with high self-efficacy or low risk perception; (3) CHBs predictions differed depending on the nature of the compensating behaviour, and were more predictive when medication intake was the compensating one. Findings only partially confirmed previous research conducted on healthy individuals who were not in an MHBC process, and emphasized the importance of considering CHBs for individuals in this process.
Peer cultural socialisation
(2019)
This study investigated how peers can contribute to cultural minority students’ cultural identity, life satisfaction, and school values (school importance, utility, and intrinsic values) by talking about cultural values, beliefs, and behaviours associated with heritage and mainstream culture (peer cultural socialisation). We further distinguished between heritage and mainstream identity as two separate dimensions of cultural identity. Analyses were based on self-reports of 662 students of the first, second, and third migrant generation in Germany (Mean age = 14.75 years, 51% female). Path analyses revealed that talking about heritage culture with friends was positively related to heritage identity. Talking about mainstream culture with friends was negatively associated with heritage identity, but positively with mainstream identity as well as school values. Both dimensions of cultural identity related to higher life satisfaction and more positive school values. As expected, heritage and mainstream identity mediated the link between peer cultural socialisation and adjustment outcomes. Findings highlight the potential of peers as socialisation agents to help promote cultural belonging as well as positive adjustment of cultural minority youth in the school context.
According to recent literature sodium bicarbonate (NaHCO3) has been proposed as a performance enhancing aid by reducing acidosis during exercise. The aim of the current review is to investigate if the duration of exercise is an essential factor for the effect
of NaHCO3. To collect the latest studies from electronic database
of PubMed, study publication time was restricted from December 2006 to December 2016. The search was updated in July 2018. The studies were divided into exercise durations of > 4 or ≤ 4 minutes for easier comparability of their effects in different exercises. Only randomized controlled trials were included in this review. Of the 775 studies, 35 met the inclusion criteria. Study design, subjects, effects as well as outcome criteria were inconsistent throughout the studies. Seventeen of these studies reported
performance enhancing effects after supplementing NaHCO3. Eleven of twenty studies with exercise duration of ≤ 4 minutes showed positive and four diverse results after supplementing NaHCO3. On the other hand six of fifteen studies with an exercise duration of >4 minutes showed performance enhancing and two studies showed diverse results. Consequently, the duration of exercise might be influential for inducing a performance enhancing effect when supplementing NaHCO3, but to which extent, remains unclear due to the inconsistencies in the study results.

While the consequences of cyberbullying victimization have received some attention in the literature, to date, little is known about the multiple types of strains in adolescents’ lives, such as whether cyberbullying victimization and peer rejection increase their vulnerability to depression and anxiety. Even though some research found that adolescents with disabilities show higher risk for cyberbullying victimization, most research has focused on typically developing adolescents. Thus, the present study focused on examining the moderating effect of peer rejection in the relationships between cyberbullying victimization, depression, and anxiety among adolescents with autism spectrum disorder. There were 128 participants (89% male; ages ranging from 11–16 years old) with autism spectrum disorder in the sixth, seventh, or eighth grade at 16 middle schools in the United States. Participants completed questionnaires on cyberbullying victimization, peer rejection, depression, and anxiety. Results revealed that cyberbullying victimization was associated positively with peer rejection, anxiety, and depression among adolescents with autism spectrum disorder. Further, peer rejection was linked positively with depression and anxiety. Peer rejection moderated the positive relationship between cyberbullying victimization and depression, but not anxiety. Implications for prevention programs and future research are discussed.
