Language Signaling High Proportions and Generics Lead to Generalizing,but Not Essentializing,for Novel Social Kinds

Generics (e.g., “Dogs bark”) are thought by many to lead to essentializing: to assuming that members of the same category share an internal property that causally grounds shared behaviors and traits, even without evidence of such a shared property. Similarly, generics are thought to increase generalizing, that is, attributing properties to other members of the same group given evidence that some members of the group have the property. However, it is not clear from past research what underlies the capacity of generic language to increase essentializing and generalizing. Is it specific to generics, or are there broader mechanisms at work, such as the fact that generics are terms that signal high proportions? Study 1 (100 5–6 year-olds, 140 adults) found that neither generics, nor high-proportion quantifiers (“most,” “many”) elicited essentializing about a novel social kind (Zarpies). However, both generics and high-proportion quantifiers led adults and, to a lesser extent, children, to generalize, with high-proportion quantifiers doing so more than generics for adults. Specifics (“this”) did not protect against either essentializing or generalizing when compared to the quantifier “some.” Study 2 (100 5–6 year-olds, 112 adults) found that neither generics nor visual imagery signaling high proportions led to essentializing. While generics increased generalizing compared to specifics and visual imagery signaling both low and high proportions for adults, there was no difference in generalizing for children. Our findings suggest high-proportion quantifiers, including generics, lead adults, and to some extent children, to generalize, but not essentialize, about novel social kinds.     

“I’m not a feminist, but…”: factors contributing to the discrepancy between pro-feminist orientation and feminist social identity

Using constructs from theories of social identity and collective action, hypotheses were developed concerning variables that predict pro-feminist orientation among those who resist the feminist label, as compared to variables that predict willingness to identify as a feminist. Predictors that were expected to be important to the latter, but not the former group, included (1) positive evaluation of feminists, (2) belief in collective action, (3) recognition of discrimination, and (4) previous exposure to feminist thought. The sample consisted of 47 male and 94 female college students (60% Anglo, 16% Asian-American, 7% African-American, 9% Hispanic, and 7% “Other”), aged 17–50 years. Using separate multiple regressions, support for the differential inclusion of all but the third variable was found. Also as predicted, the genders did not differ in pro-feminist orientation, although college women were more willing than college men to identify as feminist. Results are discussed as potentially important to understanding willingness to engage in collective advocacy.     

Self-motion perception during locomotor recalibration: more than meets the eye

Do locomotor aftereffects depend specifically on visual feedback? In 7 experiments, 116 college students were tested, with closed eyes, at stationary running or at walking to a previewed target after adaptation, with closed eyes, to treadmill locomotion. Subjects showed faster inadvertent drift during stationary running and increased distance (overshoot) when walking to a target. Overshoot seemed to saturate (i.e., reach a ceiling) at 17% after as little as 1 min of adaptation. Sidestepping at test reduced overshoot, suggesting motor specificity. But inadvertent drift effects were decreased if the eyes were open and the treadmill was drawn through the environment during adaptation, indicating that these effects involve self-motion perception. Differences in expression of inadvertent drift and of overshoot after adaptation to treadmill locomotion may have been due to different sets of ancillary cues available for the 2 tasks. Self-motion perception is multimodal.     

Disparities in access to family physicians among transgender people in Ontario,Canada

Background: Informed by the Gelberg-Andersen behavioral model for vulnerable populations, this study examined the prevalence of and factors associated with not having a family physician among transgender (trans) people in Ontario, Canada.

Methods: Data were drawn from a respondent-driven sampling (RDS) survey of trans Ontarians age 16 and above (n = 433) conducted between 2009 and 2010. All analyses were weighted using RDS II methods. Prevalence ratios were estimated using average marginal predictions from logistic regression models.

Results: An estimated 17.2% (95% CI, 11.0 to 22.9) of trans Ontarians (median age = 28.7, 77.3% White) did not have a regular family physician. In multivariable analyses accounting for other predisposing and need-related factors, transfeminine persons (trans women and non-binary persons assigned a male sex at birth) who were Indigenous and/or persons of color were less likely than other transfeminine persons to have a family doctor. In addition, trans persons who were homeless or had unstable housing were less likely to have a family doctor than those who were adequately housed.

Conclusions: These results provide the first quantitative evidence of health disparities by race and gender within a Canadian transgender population and suggest a social gradient in access to care within Ontario's “universal health insurance” system.     

童年中期儿童社交地位、社交自我知觉与孤独感的关系研究

以554名3～6年级的小学生为被试,采用量表法、同伴提名法探讨童年中期儿童社交地位、社交自我知觉与孤独感的关系。结果表明:(1)3～6年级小学生的孤独感有显著的性别差异,男生的孤独感显著高于女生。(2)不同社交地位的儿童其孤独感也不同,低接纳组儿童的孤独感显著高于一般接纳组和高接纳组,而一般接纳组与高接纳组儿童的孤独感差异不显著。(3)在高接纳组儿童中,社交自我知觉消极的儿童其孤独感显著高于社交自我知觉一般的儿童,社交自我知觉一般的儿童其孤独感显著高于社交自我知觉积极的儿童;但是在一般接纳组和低接纳组中,社交自我知觉不同的儿童其孤独感并没有显著差异。     

Identifying careless responses in questionnaire research: a serendipitous finding

The present study describes a possible method by which potentially meaningless responses to questionnaires can be easily identified. Given an inadvertent mistake in the design of a questionnaire packet, we found that 10% of respondents provided invalid responses to items.     

Clinician Perspectives of Diagnosis and Perceived Client Change in “Real World” Psychotherapy for Youth Emotional and Behavioral Disorders

We investigated the extent to which clinician-assigned diagnoses of emotional and behavioral disorders and clinicians’ perceptions of client change are consistent with structured measures of youth clinical functioning and parent/family characteristics within the context of usual care or “real world” psychotherapy. A total of 54 therapists from two publicly-funded youth outpatient mental health clinics and 128 youths and parents from the therapists’ combined caseloads were included in the study. Clinician-assigned diagnosis and youth and family demographics were collected at the initial visit, clinician-reported perceived client change was collected at 6-month follow-up, and structured measures of youth clinical functioning and parent/family characteristics were collected at both time points. Results indicate some overlap between clinician-assigned diagnosis, clinician-reported perceived client change, and structured measures of youth clinical functioning and parent/family characteristics after controlling for demographic factors. Results are discussed in terms of implications for the implementation of evidence-based practices in real world community settings.     

Chimpanzees demonstrate individual differences in social information use

Studies of transmission biases in social learning have greatly informed our understanding of how behaviour patterns may diffuse through animal populations, yet within-species inter-individual variation in social information use has received little attention and remains poorly understood. We have addressed this question by examining individual performances across multiple experiments with the same population of primates. We compiled a dataset spanning 16 social learning studies (26 experimental conditions) carried out at the same study site over a 12-year period, incorporating a total of 167 chimpanzees. We applied a binary scoring system to code each participant’s performance in each study according to whether they demonstrated evidence of using social information from conspecifics to solve the experimental task or not (Social Information Score—‘SIS’). Bayesian binomial mixed effects models were then used to estimate the extent to which individual differences influenced SIS, together with any effects of sex, rearing history, age, prior involvement in research and task type on SIS. An estimate of repeatability found that approximately half of the variance in SIS was accounted for by individual identity, indicating that individual differences play a critical role in the social learning behaviour of chimpanzees. According to the model that best fit the data, females were, depending on their rearing history, 15–24% more likely to use social information to solve experimental tasks than males. However, there was no strong evidence of an effect of age or research experience, and pedigree records indicated that SIS was not a strongly heritable trait. Our study offers a novel, transferable method for the study of individual differences in social learning.
