Developmental changes in the discrimination of dynamic human actions in infancy

Recent evidence suggests that adults selectively attend to features of action, such as how a hand contacts an object, and less to configural properties of action, such as spatial trajectory, when observing human actions. The current research investigated whether this bias develops in infancy. We utilized a habituation paradigm to assess 4-month-old and 10-month-old infants' discrimination of action based on featural, configural, and temporal sources of action information. Younger infants were able to discriminate changes to all three sources of information, but older infants were only able to reliably discriminate changes to featural information. These results highlight a previously unknown aspect of early action processing, and suggest that action perception may undergo a developmental process akin to perceptual narrowing.     

Capuchin monkeys (Cebus apella) let lesser rewards pass them by to get better rewards

Self-control is defined as foregoing an immediate reward to gain a larger delayed reward. Methods used to test self-control comparatively include inter-temporal choice tasks, delay of gratification tasks, and accumulation tasks. To date, capuchin monkeys have shown different levels of self-control across tasks. This study introduced a new task that could be used comparatively to measure self-control in an intuitive context that involved responses that required no explicit training. Capuchin monkeys (Cebus apella) were given a choice between two food items that were presented on a mechanized, revolving tray that moved those foods sequentially toward the monkeys. A monkey could grab the first item or wait for the second, but was only allowed one item. Most monkeys in the study waited for a more highly preferred food item or a larger amount of the same food item when those came later, and they inhibited the prepotent response to grab food by not reaching out to take less-preferred foods or smaller amounts of food that passed directly in front of them first. These data confirm that the mechanisms necessary for self-control are present in capuchin monkeys and indicate that the methodology can be useful for broader comparative assessments of self-control.     

Age at menarche and digit ratio (2D:4D): relationships with body dissatisfaction, drive for thinness, and bulimia symptoms in women

This study examined the hypothesis that lower prenatal androgen exposure and earlier puberty are associated with more dysfunctional eating attitudes and behaviors. Relationships between both age at menarche (AAM) and 2D:4D (a marker of prenatal androgen exposure), and EDI-2-Body Dissatisfaction, EDI-2-Drive for Thinness, and EDI-2-Bulimia scores, were examined in women using correlations and regressions. Earlier menarche was associated with higher drive for thinness after controlling for BMI and negative affect, but only in women who were not exclusively heterosexual. Higher 2D:4D was associated with higher Bulimia and Body Dissatisfaction scores, but only in exclusively heterosexual women, and relationships disappeared when covariates were controlled. Later AAM and higher 2D:4D were unique predictors of higher Bulimia scores for exclusive heterosexuals when BMI was controlled. These findings suggest future research should examine sexual orientation as a mediator or moderator of prenatal and postnatal organizational hormonal effects on women's disordered eating attitudes and behaviors.     

Preliminary support for links between media body ideal insecurity and women's shoe and handbag purchases

Two studies examined the relationship between women's insecurity-arousing comparisons with female models and shoe/handbag ownership. Idealized media images appear capable of threatening some women's sense of attractiveness and it may be that as a result, accessorizing becomes particularly appealing because it helps increase physical attractiveness without drawing attention to one's figure, the object of the threatening comparisons. In Study 1 (N=922), a correlational study, the more women reported that they feel insecure when they see attractive female models, the more shoes they tended to own. In Study 2 (N=286), we manipulated whether women saw images of attractive female models or not. The more women exhibited insecurity following exposure to the images of attractive models, the more shoes and handbags they tended to own. In both studies, these effects did not hold for ownership of trousers, an item of clothing that draws attention toward one's body.     

Detecting and Deterring Insufficient Effort Responding to Surveys

Purpose  

Responses provided by unmotivated survey participants in a careless, haphazard, or random fashion can threaten the quality of data in psychological and organizational research. The purpose of this study was to summarize existing approaches to detect insufficient effort responding (IER) to low-stakes surveys and to comprehensively evaluate these approaches.     

Effects of Fluency Versus Accuracy Training on Endurance and Retention of Assembly Tasks by Four Adolescents with Developmental Disabilities

Schools are increasingly being encouraged to teach vocational skills to middle and high school students. Although extensive research exists demonstrating the benefits of fluency instruction when teaching academic skills to this population of students, few studies have examined the importance of fluency training when teaching vocational skills. Using an alternating treatments design, the present study examined the effects of fluency versus accuracy training on 4 students’ fluency in completing 2 vocational tasks. Following the training phase, students completed each task during 20- and 40-min work sessions to assess endurance and retention of the trained skills. Overall, results suggest that the fluency condition produced greater work productivity.

Social Support and Subjective Health in Fibromyalgia: Self-Compassion as a Mediator

Individuals with fibromyalgia report lower levels of health-related quality of life (HRQL) compared to other chronically ill populations and interpersonal factors (i.e., social support) may influence risk. What is less understood is how intrapersonal factors (i.e., self-compassion) may impact the social support-HRQL linkage. We examined the association between social support and HRQL in a sample of persons with fibromyalgia and tested the potential mediating role of self-compassion. Self-identified adults in the United States with fibromyalgia (N?=?508) were recruited from state, regional, and national organizations and support groups and completed an online battery of self-report questionnaires including: Multidimensional Health Profile—Psychosocial Functioning Index, Short-Form 36 Health Survey, and Self-Compassion Scale-Short Form. Individuals with greater subjective social support reported higher levels of self-compassion and, in turn, higher mental HRQL. These findings provide greater information about psychosocial constructs and HRQL and extend our understanding of self-compassion among individuals living with fibromyalgia.

Effects of Brief Interventions on Internalizing Symptoms and Substance Use in Youth: A Systematic Review

Internalizing problems (e.g., depression, anxiety) and substance use are common among young people and often co-occur. However, youths face myriad barriers to access needed treatment, and existing evidence-based interventions tend to focus on internalizing problems or substance use, rather than both simultaneously. Brief interventions that target both problems may, therefore, be an efficient and accessible resource for alleviating youth difficulties; however, this possibility has been insufficiently evaluated. This systematic review evaluated the intervention characteristics and quality of six studies spanning 2015 to 2019 that examined intervention effects on internalizing and substance use outcomes. Based on independent calculations and author reports (respectively), 3–4 interventions significantly reduced youth internalizing symptoms; 3–5 reduced youth substance use; and 2–3 reduced symptoms in both domains. All six interventions identified substance use as a primary target. Four interventions were administered by interventionists to youths in inpatient, outpatient, primary care, or school settings. The remaining two studies delivered content through voicemail messages or an online design. Interventions ranged from?~?15 to 240 min. Results highlight the sparsity and heterogeneity of youth-focused brief interventions that have evaluated program effects on both internalizing problems and substance use outcomes, suggesting a clear need for integrated supports that are also designed for accessibility. Future investigations of brief youth-focused interventions should assess program effects on both internalizing and substance use outcomes; examine mechanisms driving the varied efficacy of identified interventions; and create, refine, and test interventions with potential to address co-occurring internalizing problems and substance use in young people.
