BMI,age, Mate Value,and Intrasexual Competition in Chilean Women

Attractiveness is the most important component of women intrasexual competition and it certainly has an impact in female’s perceived mate value (i.e., the value of an individual to the opposite sex as a potential mate). In the realm of intrasexual competition women are eager to emphasize their attractiveness and compete with rivals displaying these cues. Accordingly, age is an important feature of women’s appeal to the opposite sex; youth is highly valued by men, and is perceived by women as an important component of their attractiveness. Another trait that is a reliable cue of health and fertility is Body Mass Index (BMI). A large body of literature has associated BMI to female attractiveness. However, more information is necessary about the associations of BMI and age with mate value, and female intrasexual competition. In the present research we report two studies that examined the associations of BMI and age with estimates of self-perceived mate value and intrasexual competition in Chilean women (18–39 years). More specifically, we hypothesized inverse relationships of BMI and age with mate value (N?=?234), and intrasexual competition (N?=?308). We found partial support to our propositions. The results revealed inverse associations between BMI, mate value and mating success, but BMI with intrasexual competition were not related. In contrast, age had a strong and negative effect on intrasexual competition. We discuss our results within the framework of Evolutionary Psychology and consider the central role of attractiveness (estimated from BMI and age) in the mating strategies of women.     

A review of Evidence‐Based Evaluation of Measures for Assessing Social and Emotional Well‐Being in Indigenous Australians

Addressing low levels of social and emotional well‐being (SEWB) in Indigenous communities has been a national strategic priority for over 10 years and yet progress in assessing the impact of interventions has been slow. One of the key factors limiting the development of evidence‐based practice has been the lack of well‐validated instruments to assess SEWB and how it changes over time as a result of intervention. This article systematically reviews available measures, classifying them in terms of the evidence base that exists to support their use. It is concluded that there is an ongoing need to develop psychometrically sound, comprehensive, culturally appropriate measures to operationalise Indigenous SEWB at a population health, programme evaluation, and clinical level. It is suggested that seven pathways be followed to achieve this goal, including the need to recognise that the gold standard status for Indigenous measurement tools cannot be ascribed based on evidence‐based assessment criteria alone.     

Kinematic adaptation to sudden changes in visual task constraints during reciprocal aiming

In a series of three experiments the visual modulation of movement during a reciprocal aiming task was examined when participants were confronted with sudden changes in visually specified task constraints. Amplitude and precision constraints were manipulated independently in Experiments 1 and 2, respectively, while their simultaneous effects were analyzed in Experiment 3. Analysis of the evolution of kinematic characteristics following a sudden change in task constraints revealed two different times scales of adaptation: a rapid adjustment occurring during the deceleration phase of the first movement following change and a more gradual adaptation, affecting the kinematic pattern as a whole, occurring over the next few movements. Overall, the results indicate that visual information with respect to the adequacy of the unfolding movement is continuously monitored, even under the least constraining conditions, and serves to modulate the pattern of movement to (a) comply with the (new) task constraints and (b) optimally tailor the pattern of movement to the situation at hand. We interpret these findings in the framework of a dynamical perspective on movement organization, with information modulating the parameters of an otherwise invariant underlying dynamical structure.     

Examining patterns suggestive of acquisition during functional analyses: A consecutive controlled series of 116 cases

The functional analysis approach described by Iwata et al. (1982/1994) has been used widely to determine the variables evoking and maintaining challenging behavior. However, one potential concern with conducting functional analyses is that repeated exposure to contingencies may induce a novel functional relation. To examine the likelihood of these potential iatrogenic effects, we evaluated social test conditions of the functional analysis for 116 participants and searched for patterns of responding indicative of acquisition. Patterns suggestive of acquisition occurred in 13.70% of tangible reinforcement conditions; however, the prevalence was only slightly lower in the attention condition (8.75%). Much lower prevalence was observed for the escape condition (2.13%). When grouped by quotient score, a pattern of acquisition was just as likely to be observed in the attention condition as in the tangible condition. Additionally, patterns indicative of acquisition were no more likely to be observed with participants who emitted automatically reinforced challenging behavior.     

What Latina Mothers Think of Evidence-Based Parenting Practices: A Qualitative Study of Treatment Acceptability

Parent training has great potential to alter the developmental trajectories of young Latino children with or at risk for behavior problems. However, traditional parent training programs may seem culturally irrelevant or inappropriate to Latino parents as they promote practices that are based on white, middle class standards. The current study of treatment acceptability used focus group and key informant interviewing methodology to investigate Latina mothers’ views on the causes of young children's misbehavior and the acceptability of evidence-based parenting strategies. The sample consisted of Spanish- and English-speaking Latina mothers of 3- to 6-year-olds recruited from day-care centers and preschools in New York City. Focus groups were conducted with 34 mothers, and key informant interviews with 5 mothers whose children had behavior problems. Results showed that the most commonly viewed causes of child misbehavior were child temperament, fighting in the home, and negative peer influence. Mothers found some evidence-based parenting strategies acceptable (e.g., the use of praise, social rewards) and others objectionable (e.g., selective ignoring in pubic situations, the elimination of spanking). For some strategies, there was little consensus on its acceptability (e.g., time-out). Taken together, results highlight the critical need for aligning parent and clinician goals at the outset of treatment, and of including a strong psychoeducational component in parent training programs because not all of its components are consistent with Latino cultural norms and beliefs.     

Uncomfortable images in art and nature

The ratings of discomfort from a wide variety of images can be predicted from the energy at different spatial scales in the image, as measured by the Fourier amplitude spectrum of the luminance. Whereas comfortable images show the regression of Fourier amplitude against spatial frequency common in natural scenes, uncomfortable images show a regression with disproportionately greater amplitude at spatial frequencies within two octaves of 3 cycles deg(-1). In six studies, the amplitude in this spatial frequency range relative to that elsewhere in the spectrum explains variance in judgments of discomfort from art, from images constructed from filtered noise, and from art in which the phase or amplitude spectra have been altered. Striped patterns with spatial frequency within the above range are known to be uncomfortable and capable of provoking headaches and seizures in susceptible persons. The present findings show for the first time that, even in more complex images, the energy in this spatial-frequency range is associated with aversion. We propose a simple measurement that can predict aversion to those works of art that have reached the national media because of negative public reaction.     

A quantitative review of overjustification effects in persons with intellectual and developmental disabilities

The overjustification hypothesis suggests that extrinsic rewards undermine intrinsic motivation. Extrinsic rewards are common in strengthening behavior in persons with intellectual and developmental disabilities; we examined overjustification effects in this context. A literature search yielded 65 data sets permitting comparison of responding during an initial no‐reinforcement phase to a subsequent no‐reinforcement phase, separated by a reinforcement phase. We used effect sizes to compare response levels in these two no‐reinforcement phases. Overall, the mean effect size did not differ from zero; levels in the second no‐reinforcement phase were equally likely to be higher or lower than in the first. However, in contrast to the overjustification hypothesis, levels were higher in the second no‐reinforcement phase when comparing the single no‐reinforcement sessions immediately before and after reinforcement. Outcomes consistent with the overjustification hypothesis were somewhat more likely when the target behavior occurred at relatively higher levels prior to reinforcement.
