Bimodal familiarization re-sensitizes 12-month-old infants to other-race faces

Perceptual narrowing in the domain of face perception typically begins to reduce infants’ sensitivity to differences distinguishing other-race faces from approximately 6 months of age. The present study investigated whether it is possible to re-sensitize Caucasian 12-month-old infants to other-race Asian faces through statistical learning by familiarizing them with different statistical distributions of these faces. The familiarization faces were created by generating a morphed continuum from one Asian face identity to another. In the unimodal condition, infants were familiarized with a frequency distribution wherein they saw the midpoint face of the morphed continuum the most frequently. In the bimodal condition, infants were familiarized with a frequency distribution wherein they saw faces closer to the endpoints of the morphed continuum the most frequently. After familiarization, infants were tested on their discrimination of the two original Asian faces. The infants’ looking times during the test indicated that infants in the bimodal condition could discriminate between the two faces, while infants in the unimodal condition could not. These findings therefore suggest that 12-month-old Caucasian infants could be re-sensitized to Asian faces by familiarizing them with a bimodal frequency distribution of such faces.     

Attentional engagement during syllable discrimination: The role of salient prosodic cues in 6- to 8-month-old infants

Prosodic cues drive speech segmentation and guide syllable discrimination. However, less is known about the attentional mechanisms underlying an infant's ability to benefit from prosodic cues. This study investigated how 6- to 8-month-old Italian infants allocate their attention to strong vs. weak syllables after familiarization with four repeats of a single CV sequence with alternating strong and weak syllables (different syllables on each trial). In the discrimination test-phase, either the strong or the weak syllable was replaced by a pure tone matching the suprasegmental characteristics of the segmental syllable, i.e., duration, loudness and pitch, whereas the familiarized stimulus was presented as a control. By using an eye-tracker, attention deployment (fixation times) and cognitive resource allocation (pupil dilation) were measured under conditions of high and low saliency that corresponded to the strong and weak syllabic changes, respectively. Italian learning infants were found to look longer and also to show, through pupil dilation, more attention to changes in strong syllable replacement rather than weak syllable replacement, compared to the control condition. These data offer insights into the strategies used by infants to deploy their attention towards segmental units guided by salient prosodic cues, like the stress pattern of syllables, during speech segmentation.     

Angry rumination moderates the association between perceived ethnic discrimination and risky behaviors

Perceived ethnic discrimination (PED) is associated with increased engagement in risky behaviors in ethnic minority emerging adults. Risky behaviors may reflect efforts to cope with emotional distress like depression or anxiety resulting from PED, particularly for individuals with poor emotion regulation skills. We hypothesized that the association between PED and risky behaviors would be particularly strong for emerging adults with tendencies for angry rumination. We further hypothesized that increased depressive and anxious symptoms would mediate the effect of the PED-rumination interaction on risky behaviors. In this survey study, 155 ethnic minority college students completed measures of PED, depressive and anxiety symptoms, trait angry rumination, and risky behaviors. Analyses revealed that angry rumination moderated the association between PED and greater risky behaviors. Depressive and anxiety symptoms did not mediate this effect. Although cross-sectional, these findings suggest that individuals with poor coping skills may be especially likely to respond to stressors such as PED by engaging in risky behaviors. Implications include using rumination-focused interventions in order to prevent engagement in risky behaviors in ethnic minority emerging adults.     

A gentle reminder that mean does not imply modal behavior: Few are in-group biased in minimal groups

Previous research reports that people organized into newly formed, arbitrary groups (i.e., minimal groups) are on average in-group biased. However, that people on average behave in a certain way does not imply that most people behave that way. Here, I report four studies (n = 224) demonstrating in-group biased average behaviors driven by a minority of about 30% participants. Further, only 14% reported allocating resources in a group-biased manner because they “favored the in-group.” I investigate and discuss how methodological issues related to non-normally distributed data, not taking participants’ intentions into account, and using fixed response matrices can lead to overestimations of how widespread in-group bias is in minimal groups.     

Non-binary and binary transgender youth: Comparison of mental health,self-harm,suicidality, substance use and victimization experiences

ABSTRACT

?Background: Little research has compared the mental health and victimization experiences of non-binary youth depending on their sex assigned at birth (SAAB), or compared these two groups with binary transgender youth.

Aims: To compare mental health, self-harm and suicidality, substance use and victimization experiences between non-binary and binary transgender young adults, both male assigned at birth (MAAB) and female assigned at birth (FAAB).

Methods: Online survey data from 677 participants from the “Youth Chances” community study of 16 to 25 year olds in the United Kingdom was analyzed, comparing across binary participants (transgender females (n = 105) and transgender males (n = 210)) and non-binary participants (MAAB (n = 93) and FAAB (n = 269)).

Results: Female SAAB participants (binary and non-binary) were more likely to report a current mental health condition and history of self-harm than male SAAB participants (binary and non-binary). Similarly, female SAAB participants (binary and non-binary) were more likely to report childhood sexual abuse than male SAAB participants (binary and non-binary); the reverse pattern was found for lifetime physical assault relating to being LGBTQ. Non-binary MAAB participants were less likely than the other groups to report past suicide attempts and previous help-seeking for depression/anxiety. Binary participants reported lower life satisfaction than non-binary participants. For all four groups, mental health problems, self-harm, suicidality, alcohol use and victimization experiences were generally higher than that of youth in general population studies.

Conclusions: These findings highlight the importance of considering both non-binary versus binary gender identity and SAAB in relation to mental health problems, self-harm, suicidality and substance use in transgender youth. The roles of sexual abuse, other abuse and discrimination in contributing to increased rates of mental illness and self-harm in non-binary and binary transgender individuals, particularly those who were assigned female at birth, relative to those assigned male, require investigation.     

Benevolent ageism: Attitudes of overaccommodative behavior toward older women

ABSTRACT

Stereotypes of older adults fit a paternalistic pattern, including elevated warmth and lowered competence, yet little effort has been made to elucidate this in an everyday context. This phenomenon was examined with an experimental vignette, in which a woman was offered unnecessary help; specifically, the age (young vs. old) and the independence (accepting vs. declining assistance) of the woman were manipulated. Attributions from a college-age sample toward the woman were examined. In the older conditions, hypotheses were confirmed that participants approved overaccommodative behaviors, endorsed higher warmth and lower competence, and attitudes were modified when the older women contradicted the paternalistic stereotype by declining assistance. That is, competence was modifiable for older women, whereas warmth was not. Implications of these findings as possible evidence of benevolent ageism and the malleability of the Stereotype Content Model are discussed.     

The Paradox Between Integration and Perceived Discrimination Among American Muslims

Muslim Americans are increasingly integrated into American life, displaying high socioeconomic status, political participation, and adherence to American values. However, they are evaluated more negatively than many other racial, ethnic, and religious minorities and are frequent targets of discrimination. This article examines the mismatch between the integration of Muslims and their poor reception. Drawing on theories of cultural fluency and cognitive dissonance, we argue that cultural integration can exacerbate, rather than mitigate, perceived discrimination because integrated individuals are socialized to expect fair treatment and can recognize and decode even subtle forms of discrimination due to high levels of cultural and language fluency. Using three nationally representative surveys and an opt-in, online study of American Muslims between 2007 and 2017, we find that integrated Muslims are consistently more likely than their counterparts to report individual- and group-level societal and political discrimination. The paradox between adopting the host culture and feeling marginalized poses a challenge to the assumption that integration naturally leads to a sense of belonging among minorities, with important implications for liberal democracies.
