You are how you speak: The roles of vocal pitch and semantic cues in shaping social perceptions.

Social perceptions of speakers are influenced by their voice information, including vocal characteristics and semantic content. Our study investigated how individuals' warmth- and competence-related perceptions of speakers were affected by vocal pitch levels (i.e., high/low) and three kinds of semantic cues (i.e., prosocial, antisocial, and neutral) simultaneously. We have three key findings. First, antisocial cues negatively affected social perceptions, regardless of speakers' gender. However, prosocial cues did not have positive impacts on evaluations of speakers because ratings were similar between prosocial cues and neutral cues. Second, female vocal pitch mattered for warmth-related perceptions but not for competence-related perceptions. The role of semantic cues should be additionally considered when investigating the impact of male vocal pitch on these perceptions. For example, higher-pitched men in prosocial contexts were perceived as warmer, while low-pitched men in antisocial contexts were judged as more competent. Third, the connection between vocal pitch and two kinds of perceptions showed an opposite trend, in which high pitch was related to more warmth but less competence, while the low pitch was associated with less warmth but more competence. These findings extend the understanding of the role of vocal pitch in the formation of stereotypes of strangers in different semantic contexts.

Longitudinal Links Between Parental Failure Mindsets, Helicopter Parenting, and Fixed Mindset of Intelligence in Adolescents.

Evidence for the prospective associations among parental failure mindset, helicopter parenting, and children's intelligence mindset is lacking. This three-wave longitudinal study (12 months apart between waves) addressed this research gap by testing whether perceived maternal helicopter parenting mediated the link between perceived maternal failure mindset and intelligence mindset. Participants included 525 Chinese adolescents (47.2% girls, Mage = 15.41 years, SD = 0.22). Random-intercept cross-lagged analysis suggests that mothers with stronger failure-is-debilitating mindsets are more likely to engage in helicopter parenting, which may in turn contribute to stronger endorsements of a fixed mindset of intelligence in their adolescent children. The relation between maternal helicopter parenting and children's intelligence mindset appeared to be reciprocal, i.e., children's fixed mindset may elicit more helicopter parenting over time.

Effects of Biological Determinism on Beliefs and Attitudes About Transgender People: Psychological Essentialism and Biased Assimilation.

This experimental study examined the effects of biological attributions on individuals' beliefs and attitudes toward transgender people and the moderating role of right-wing authoritarianism (RWA). We randomly assigned 183 Chinese university students (men: n = 85, women: n = 98) to read one of three fictitious articles. The first article suggested that transgender identity was causally linked to biology (biological determinist condition), the second one highlighted the interplay between biological and environmental factors (epigenetic condition), whereas the third article did not mention the origins of transgender identity (control condition). Consistent with the biased assimilation hypothesis, the effects of biological attributions depended on individual differences in RWA. Low-RWA participants showed higher levels of naturalness and discreteness/homogeneity beliefs about transgender identity in the biological determinist condition than those in the control condition. By contrast, high-RWA participants displayed higher levels of discreteness/homogeneity beliefs but similar levels of naturalness beliefs when they read the biological determinist message compared with the control group. Low-RWA participants showed higher levels of naturalness but similar levels of discreteness/homogeneity beliefs in the epigenetic condition compared with the control, whereas high-RWA participants exhibited lower levels of naturalness and higher levels of discreteness/homogeneity beliefs when they read the epigenetic message compared with the control group. This study also suggests that, contrary to attribution theory, presenting information regarding the biological basis of transgender identity does not necessarily lead to more positive attitudes because (a) it triggers essentialist thinking and (b) the effects of biological attributions depend on recipients' authoritarian dispositions.

Cross-notation knowledge of rational numbers predicts fraction arithmetic.

BACKGROUND: Recent research showed that cross-notation magnitude knowledge of fractions and decimals was related to better performance in fraction arithmetic, but it remains unclear whether it made an independent contribution to fraction arithmetic longitudinally when other cognitive variables are considered. AIMS: To examine the extent to which children's earlier knowledge of cross-notation magnitude predicted subsequent performance in fraction addition and subtraction as well as fraction multiplication and division longitudinally. SAMPLE: Three hundred and fifty-four Chinese children (Mage = 112.1 months). METHODS: During the first wave of assessment, a range of cognitive abilities of children were measured, including within-notation fraction and decimal magnitude comparisons, whole-number arithmetic fluency, non-verbal intelligence, attentive behaviours, counting recall, word-level reading, and phonological awareness. Twelve months later, the same children were assessed again with two tasks of fraction arithmetic: fraction addition and subtraction as well as fraction multiplication and division. RESULTS AND CONCLUSIONS: Multiple linear regressions showed that within-notation fraction and decimal magnitude knowledge predicted fraction addition and subtraction longitudinally, after the effects of working memory, nonverbal intelligence, language skills, attentive behaviour, and whole-number arithmetic were controlled. Cross-notation magnitude knowledge made independent contributions to fraction addition and subtraction longitudinally beyond the influence of within-notation fraction and decimal magnitude knowledge and other covariates. However, within-notation fraction and decimal magnitude knowledge were not associated with fraction multiplication and division, whereas cross-notation magnitude knowledge remained a unique predictor. These findings suggest that it may be useful to incorporate cross-notation knowledge in the assessments of children's mathematics abilities and teaching.

Body weight contingent self-worth predicts depression in adolescent girls: The roles of self-esteem instability and interpersonal sexual objectification.

This 3-year longitudinal study examined the extent to which body weight contingent self-worth (CSW) predicted depressive symptoms in 439 adolescent girls and the roles of unstable self-esteem and interpersonal sexual objectification in this association. Half-longitudinal mediation showed that the indirect effect of body weight CSW on depression via instability of self-esteem was significant. Prior levels of body weight CSW predicted increases in unstable self-esteem, which predicted increments in depressive symptoms over time. However, earlier levels of depression did not significantly predict increases in self-esteem instability. Moderation analyses indicated that the indirect effect was conditional upon individuals' experience of interpersonal sexual objectification. The positive link between body weight CSW and unstable self-esteem was stronger in girls who experienced more interpersonal sexual objectification. The direct effect of body weight CSW on depression was also moderated by interpersonal sexual objectification. Taken together, basing self-worth on body weight appears to be a risk factor for depression through its association with unstable self-esteem in adolescent girls and sexually objectifying experiences serve to exacerbate the connection between body weight CSW and adverse outcomes.
