Normal body, beautiful body: discrepant perceptions reveal a pervasive 'thin ideal' from childhood to adulthood

We aimed to determine the developmental trajectory for the 'thin ideal' by evaluating discrepancies in objective ratings of female body attractiveness and normality in a sample of children and adults. One hundred and sixty Australian middle class male and female participants from four different age groups (range: 4-26 years) viewed sets of photos depicting female bodies that varied systematically on the dimension of width. Six photo sets were presented. Participants ranked three sets according to their perceptions of body normality and ranked the other three sets in terms of body attractiveness. Results indicated that for all age groups, attractiveness ratings were significantly thinner than normality ratings. These findings indicate that the thin ideal is already present in primary school children and remains stable into adulthood, with concerning implications for body dissatisfaction and related disorders. Further research is required to clarify the developmental origins of preferences for thinner-than-normal female bodies.     

The Social Construction of Copyright Ethics and Values

This study is based on analysis of copyright policies and 26 interviews with science and engineering faculty at three research universities on the topic of copyright beliefs, values, and practices, with emphasis on copyright of instructional materials, courseware, tools, and texts. Given that research universities now emphasize increasing external revenue flows through marketing of intellectual property, we expected copyright to follow the path of patents and lead to institutional emphasis of policies and practices that enhanced universities’ intellectual property portfolios, accompanied by an increase in copyrighting by professors. Although this pattern occurred with regard to institutions, professors offered a more varied pattern, with some fully participating in commercialization of copyright and embracing entrepreneurial values, while others resisted or subverted commercial activity in favor of traditional science and engineering values.     

Participant loss due to "fussiness" in infant visual paradigms: a review of the last 20 years

One hundred and one published articles that used visual habituation or violation-of-expectation techniques with infants of 12 months or younger were surveyed. Information was compiled on the number of infants who failed to complete experimental procedures due to "fussiness" or other factors. Also noted for each experiment was whether or not infants as a group demonstrated differential responding to the test display. On average 13.7% (range 0-62%) of infants failed to complete these visual procedures as a result of fussiness. There was no correlation between experimental outcome and infant attrition due to fussiness or to any other factor. We thus found no evidence to suggest that differential exclusion rates systematically influence experimental outcomes. However, we urge researchers to provide operational definitions of "fussiness."     

Initial Attraction to Organizations: The influence of trait inferences

Organization personality perceptions have been defined as the set of personality characteristics associated with organizations. Previous research supports five distinct factors of organization personality perceptions: Boy Scout, Innovativeness, Dominance, Thrift, and Style. The purpose of this research was to understand how individuals' initial attraction to firms is influenced by their perceptions of the degree to which firms display these traits. Results of the present investigation indicated that organization personality perceptions accounted for significant variance in initial organizational attraction, after controlling for perceptions of the degree to which the jobs at the organizations offer traditional attributes. In addition, several self‐rated Big Five personality characteristics interacted with dimensions of organization personality perceptions to influence attraction. Implications for the use of organization personality in future recruitment research are discussed.     

Toddler subtraction with large sets: further evidence for an analog-magnitude representation of number

Two experiments were conducted to test the hypothesis that toddlers have access to an analog-magnitude number representation that supports numerical reasoning about relatively large numbers. Three-year-olds were presented with subtraction problems in which initial set size and proportions subtracted were systematically varied. Two sets of cookies were presented and then covered. The experimenter visibly subtracted cookies from the hidden sets, and the children were asked to choose which of the resulting sets had more. In Experiment 1, performance was above chance when high proportions of objects (3 versus 6) were subtracted from large sets (of 9) and for the subset of older participants (older than 3 years, 5 months; n = 15), performance was also above chance when high proportions (10 versus 20) were subtracted from the very large sets (of 30). In Experiment 2, which was conducted exclusively with older 3-year-olds and incorporated an important methodological control, the pattern of results for the subtraction tasks was replicated. In both experiments, success on the tasks was not related to counting ability. The results of these experiments support the hypothesis that young children have access to an analog-magnitude system for representing large approximate quantities, as performance on these subtraction tasks showed a Weber's Law signature, and was independent of conventional number knowledge.     

Individual differences in neonatal “imitation” fail to predict early social cognitive behaviour

The influential hypothesis that humans imitate from birth – and that this capacity is foundational to social cognition – is currently being challenged from several angles. Most prominently, the largest and most comprehensive longitudinal study of neonatal imitation to date failed to find evidence that neonates copied any of nine actions at any of four time points (Oostenbroek et al., [2016] Current Biology, 26, 1334–1338). The authors of an alternative and statistically liberal post‐hoc analysis of these same data (Meltzoff et al., [2017] Developmental Science, 21, e12609), however, concluded that the infants actually did imitate one of the nine actions: tongue protrusion. In line with the original intentions of this longitudinal study, we here report on whether individual differences in neonatal “imitation” predict later‐developing social cognitive behaviours. We measured a variety of social cognitive behaviours in a subset of the original sample of infants (N = 71) during the first 18 months: object‐directed imitation, joint attention, synchronous imitation and mirror self‐recognition. Results show that, even using the liberal operationalization, individual scores for neonatal “imitation” of tongue protrusion failed to predict any of the later‐developing social cognitive behaviours. The average Spearman correlation was close to zero, mean r_s = 0.027, 95% CI [?0.020, 0.075], with all Bonferroni adjusted p values > .999. These results run counter to Meltzoff et al.'s rebuttal, and to the existence of a “like me” mechanism in neonates that is foundational to human social cognition.     

Examining creative performance over time using hierarchical linear modeling: An illustration using film directors

Longitudinal performance of 73 film directors are examined using hierarchical linear modeling (HLM). The HLM analyses model intraindividual performance trajectories (i.e., performance change over time) and interindividual differences in the trajectory parameters (i.e., initial status and rate of change in performance). Results reveal that as a group, directors' performance over careers, measured by critics' ratings, can be described using a quadratic trajectory with an increase in ratings following the initial film, followed by an eventual decline in ratings in later films. However, at the intraindividual level, directors differ in their initial status as well as rate of linear change, and some directors follow an accelerating or decelerating performance pattern. These interindividual differences in initial status, direction of change, and rate of change are related to the mean number of films per year directed by the individual. Implications and future research challenges for modeling longitudinal creative performance with HLM are discussed.     

Do young infants respond socially to human hands?

This study revealed that 4- and 6-month-old infants produced social-communicative behaviours only in response to faces, and not in response to hands. However, infants’ spontaneous responses to hands were unique in that they scanned the space above the hands, perhaps searching for a face.     

Toddlers' categorization of typical and scrambled dolls and cars

Previous research has demonstrated discrimination of scrambled from typical human body shapes at 15–18 months of age [Slaughter, V., & Heron, M. (2004). Origins and early development of human body knowledge. Monographs of the Society for Research in Child Development, 69]. In the current study 18-, 24- and 30-month-old infants were presented with four typical and four scrambled dolls in a sequential touching procedure, to assess the development of explicit categorization of human body shapes. Infants were also presented with typical and scrambled cars, allowing comparison of infants’ categorization of scrambled and typical exemplars in a different domain. Spontaneous comments regarding category membership were recorded. Girls categorized dolls and cars as typical or scrambled at 30 months, whereas boys only categorized the cars. Earliest categorization was for typical and scrambled cars, at 24 months, but only for boys. Language-based knowledge, coded from infants’ comments, followed the same pattern. This suggests that human body knowledge does not have privileged status in infancy. Gender differences in performance are discussed.
