What causes scale errors in children?

A recent article by DeLoache et al. has documented an intriguing phenomenon in the development of action planning in young children. When children act on toy replicas of larger objects they make scale errors that are consistent with the full-sized object. Although the actions selected are inappropriate, their execution accurately takes into account the true size of the target. This phenomenon permits tests of the predictions of the perception-action and planning-control models of vision for action.     

What Do North American Babies Hear? A large‐scale cross‐corpus analysis

A range of demographic variables influences how much speech young children hear. However, because studies have used vastly different sampling methods, quantitative comparison of interlocking demographic effects has been nearly impossible, across or within studies. We harnessed a unique collection of existing naturalistic, day‐long recordings from 61 homes across four North American cities to examine language input as a function of age, gender, and maternal education. We analyzed adult speech heard by 3‐ to 20‐month‐olds who wore audio recorders for an entire day. We annotated speaker gender and speech register (child‐directed or adult‐directed) for 10,861 utterances from female and male adults in these recordings. Examining age, gender, and maternal education collectively in this ecologically valid dataset, we find several key results. First, the speaker gender imbalance in the input is striking: children heard 2–3× more speech from females than males. Second, children in higher‐maternal education homes heard more child‐directed speech than those in lower‐maternal education homes. Finally, our analyses revealed a previously unreported effect: the proportion of child‐directed speech in the input increases with age, due to a decrease in adult‐directed speech with age. This large‐scale analysis is an important step forward in collectively examining demographic variables that influence early development, made possible by pooled, comparable, day‐long recordings of children's language environments. The audio recordings, annotations, and annotation software are readily available for reuse and reanalysis by other researchers.     

Is Justice Binary?: A Free‐Will‐Related Exploration

Abstract: This article asks whether justice is binary, whether matters are either‐or with respect to it. This question has been inexplicably neglected, and the elementary conceptual work has not been done. We consider this question through exploring the implications of free‐will‐related justice. We see that there are actually two questions of very different scope here, and that two distinct notions of binarity need to be distinguished. In the process, the plausibility of considering justice as a binary notion is evaluated.     

Naturally better? A review of the natural‐is‐better bias

People are frequently exposed to products and services that are labeled natural (e.g., Nature Made Vitamins or GoJo Natural Orange Hand Cleaner). The frequency with which this label is used suggests that it delivers an advantage in marketing and sales. Our review examines the preference for and perception of naturalness and reveals that people have a bias for items described as natural in many domains including foods, medicine, beauty products, cigarettes, and lighting. These preferences abound even when the natural item is identical or not objectively better than the non‐natural or synthetic item. We believe this bias may be driven by a natural‐is‐better default belief as well as the belief that natural items are safer than non‐natural items. Although a bias for natural items is apparent, this literature is in its infancy, and we suggest three areas that will help build and refine the empirical research base and theory: the measurement of behavior, the examination of individual differences, and the development of methods for reducing the bias. A better understanding of the naturalness bias relevant to these areas will lead to a more comprehensive understanding of the area, including factors that may cause and reduce it.     

Delusion‐proneness or miscomprehension? A re‐examination of the jumping‐to‐conclusions bias

Previous research has consistently shown that individuals with delusions typically exhibit a jumping‐to‐conclusions (JTC) bias when administrated the probabilistic reasoning ‘beads task’ (i.e., decisions made on limited evidence and/or decisions over‐adjusted in light of disconfirming evidence). However, recent work in this area has indicated that a lack of comprehension of the task may be confounding this finding. The purpose of the present study was to evaluate the influence of task administration, delusion‐proneness, and miscomprehension on the elucidation of the JTC bias. A total of 92 undergraduate university students were divided into one of two task conditions (i.e., non‐computerised and computerised) and were further identified as either delusion‐prone or non‐delusion‐prone and as comprehending or non‐comprehending the task. Overall, 25% of the sample demonstrated a JTC bias, and just over half made illogical responses consistent with a failure to comprehend the task. Qualitative evidence of comprehension revealed that these ‘illogical responses’ were being driven by a misunderstanding of task instructions. The way the task was administrated and levels of delusion‐proneness did not significantly influence JTC. However, miscomprehending participants were significantly more likely to exhibit the bias than those who did comprehend. These results suggest that miscomprehension rather than delusion‐proneness may be driving the JTC bias, and that future research should include measures of miscomprehension.     

Cultural differences in self‐recognition: the early development of autonomous and related selves?

Fifteen‐ to 18‐month‐old infants from three nationalities were observed interacting with their mothers and during two self‐recognition tasks. Scottish interactions were characterized by distal contact, Zambian interactions by proximal contact, and Turkish interactions by a mixture of contact strategies. These culturally distinct experiences may scaffold different perspectives on self. In support, Scottish infants performed best in a task requiring recognition of the self in an individualistic context (mirror self‐recognition), whereas Zambian infants performed best in a task requiring recognition of the self in a less individualistic context (body‐as‐obstacle task). Turkish infants performed similarly to Zambian infants on the body‐as‐obstacle task, but outperformed Zambians on the mirror self‐recognition task. Verbal contact (a distal strategy) was positively related to mirror self‐recognition and negatively related to passing the body‐as‐obstacle task. Directive action and speech (proximal strategies) were negatively related to mirror self‐recognition. Self‐awareness performance was best predicted by cultural context; autonomous settings predicted success in mirror self‐recognition, and related settings predicted success in the body‐as‐obstacle task. These novel data substantiate the idea that cultural factors may play a role in the early expression of self‐awareness. More broadly, the results highlight the importance of moving beyond the mark test, and designing culturally sensitive tests of self‐awareness.     

How does social essentialism affect the development of inter‐group relations?

Psychological essentialism is a pervasive conceptual bias to view categories as reflecting something deep, stable, and informative about their members. Scholars from diverse disciplines have long theorized that psychological essentialism has negative ramifications for inter‐group relations, yet little previous empirical work has experimentally tested the social implications of essentialist beliefs. Three studies (N = 127, ages 4.5–6) found that experimentally inducing essentialist beliefs about a novel social category led children to share fewer resources with category members, but did not lead to the out‐group dislike that defines social prejudice. These findings indicate that essentialism negatively influences some key components of inter‐group relations, but does not lead directly to the development of prejudice.     

Employees’ perception of diversity management practices: scale development and validation

Scholars and practitioners are paying increasing attention to diversity management (DM). Despite this increase and an expanding literature, there exists a lack of psychometrically sound scales to measure DM practices and none that capture employees’ perception of DM practices (EPDMP). This dearth in literature has thus hindered DM research. To fill the gap, in the present paper, using a qualitative study and 3 quantitative studies in a sample of 590 employees across various sectors in the UK, a 9-item uni-dimensional EPDMP scale is developed and validated. Results from content adequacy, reliability, convergent, discriminant, nomological and incremental predictive validity assessments provide support for the measures use in diagnostic and theory testing efforts. This paper concludes with a discussion of the implications for theory, management practice and future research.     

A Meta‐Analytic Investigation of the Within‐Person Self‐Efficacy Domain: Is Self‐Efficacy a Product of Past Performance or a Driver of Future Performance?

We conducted a meta‐analysis to determine whether the within‐person self‐efficacy/performance relationship is positive, negative, or null and to compare the strength of the self‐efficacy/performance and past performance/self‐efficacy within‐person relationships. The self‐efficacy/performance within‐person corrected correlation was .23 but was weak and nonsignificant (ρ = .06) when controlling for the linear trajectory, revealing that the main effect was spurious. The past performance/self‐efficacy within‐person corrected correlation was .40 and remained positive and significant (ρ = .30) when controlling for the linear trajectory. The moderator results revealed that at the within‐person level of analysis: (a) self‐efficacy had at best a moderate, positive effect on performance and a null effect under other moderating conditions (ρ ranged from –.02 to .33); (b) the main effect of past performance on self‐efficacy was stronger than the effect of self‐efficacy on performance, even in the moderating conditions that produced the strongest self‐efficacy/performance relationship; (c) the effect of past performance on self‐efficacy ranged from moderate to strong across moderating conditions and was statistically significant across performance tasks, contextual factors, and methodological moderators (ρ ranged from .18 to .52). Overall, this suggests that self‐efficacy is primarily a product of past performance rather than the driving force affecting future performance.     

The impact of children’s lexical and morphosyntactic knowledge on narrative competence development: A prospective cohort study

The authors investigate the contribution of children's early comprehension of relational terms and morphosyntactic knowledge to the development of narrative competence in kindergarten and Grade 1. Narrative competence was assessed through the cohesion, coherence, and structure of children’s productions. The participants in this study were 714 Italian children. The authors measured their oral narrative competence through a storytelling task at the beginning and end of the kindergarten year. A total of 115 children were randomly selected and followed through Grade 1, and their narrative competence was measured again. According to the path analysis model, early morphosyntactic knowledge contributes to explain narrative competence in Grade 1. Early comprehension of relational terms contributes to narrative competence at the end of the school year. These findings confirm the importance of exploring the influence of early language skills on narrative competence development and suggests early intervention at the level of language antecedents of narrative competence.     

Wall‐to‐Wall or Patchwork? Linkages: Vehicles of Partnership

Career development services are often poorly interlinked. They overlap, yet they are can also be too far apart. They reach out, yet they do not always reach out to those who need the services the most. With examples from Denmark, this article indicates how and why career development services are linked in partnerships at different levels. Is a wall‐to‐wall carpet of career development services to be preferred over a patchwork quilt?     

Predictors of re‐employment: A question of attitude,behavior, or gender?

This longitudinal study examined the predictive value of attitudes, personal‐related variables, job search behaviour, and demographic variables on re‐employment among 142 assembly workers who had been made redundant. Participants completed a questionnaire within a week after leaving their jobs, and another 15 months later. Results of hierarchical logistic regression revealed that gender (being male), was the strongest predictor of re‐employment. Willingness to relocate and desire to change occupation also increased the odds of re‐employment 15 months after dismissal. On the other hand ‐ having children at home and anonymous‐passive job‐search behaviour, which is more prevalent among women, decreased the odds for re‐employment. The study is contributing to research by revealing gender differences in job search behaviour and the importance of focusing qualitative differences instead of merely quantitative measures in job‐search behaviour. And even more important, despite attitude and job‐search behaviour, there is still differences that seems to be related to gender and family responsibility.     

Cosmetic Surgery: A Common and Accepted Form of Self‐Improvement?1

The pursuit of beauty through alteration of physical appearance is a growing trend. Rates of cosmetic surgery have soared, suggesting that surgery is a common, acceptable solution to the desire for self‐improvement. Despite indications that surgeries are increasing in frequency, there have been few empirical investigations about popular attitudes toward cosmetic surgery. In the present study, 302 female undergraduate students were surveyed. Approximately 3% of the sample had undergone cosmetic surgery themselves, and half knew at least 1 person among their friends and family who had undergone cosmetic surgery. As hypothesized, approval and reported future likelihood of cosmetic surgery were predicted by greater media exposure, greater vicarious experience of cosmetic surgery, and greater importance of appearance to self‐worth. No significant differences among ethnic groups were found.     

What makes relational reasoning smart? Revisiting the perceptual‐to‐relational shift in the development of generalization

Development of reasoning is often depicted as involving increasing use of relational similarities and decreasing use of perceptual similarities (‘the perceptual‐to‐relational shift’). We argue that this shift is a special case of a broader developmental trend: increasing sensitivity to the predictive accuracy of different similarity types. To test this hypothesis, we asked participants (3‐, 4‐, 5‐year‐olds and adults) to generalize novel information on two types of problems – offspring problems, where relational matches yield accurate generalizations, and prey problems, where perceptual matches yield accurate generalizations. On offspring problems, we replicated prior findings of increasing relational matches with age. However, we observed decreasing relational matches on prey problems. Provided feedback on their responses, 3‐year‐olds showed the same trend. Findings suggest that the relational shift commonly observed in categorization and analogical reasoning may reflect a general increase in children's sensitivity to cue validity rather than an overall preference to generalize over perceptual similarity.     

Prolonged development of auditory skills: A role for perceptual anchoring?

Many auditory skills continue to develop beyond infancy and even into adolescence, but the factors underlying this prolonged development remain poorly understood. Of interest here is the contribution of on-line statistical learning of stimulus repetitions (anchoring) to the development of auditory spectral and temporal discrimination, as well as the potential contributions of auditory attention and working memory. Children, aged 6–13 years, as well as adults (age range: 21–33 years) were tested on auditory frequency and duration discrimination. Each type of discrimination was measured in two conditions (XAB and XXXAB) designed to afford different levels of anchoring by varying the number of repetitions of a standard stimulus (X) prior to the presentation of the test tone (A or B) in each trial. Auditory attention and working memory were also assessed. Whereas duration and frequency discrimination in either condition did not reach adult level prior to 11 years of age, the magnitude of the anchoring effect was similar across ages. These data suggest that perceptual anchoring matures prior to the attainment of adult-like discrimination thresholds. Likewise, neither attention nor working memory could account for the observed developmental trajectories. That auditory discrimination and anchoring follow dissociable developmental trajectories suggests that different factors might contribute to the development of each. We therefore conclude that although anchoring might be necessary for attaining good auditory discrimination, it does not account for the prolonged development of auditory frequency and duration discrimination in school-aged children.     

Discrimination: A Challenge to First‐Person Authority?

It is no surprise that empirical psychology refutes, again and again, assumptions of uneducated common sense. But some puzzlement tends to arise when scientific results appear to call into question the very conceptual framework of the mental to which we have become accustomed. This paper shall examine a case in point: Experiments on colour-discrimination have recently been taken to refute an assumption of first-person authority that appears to be constitutive of our ordinary notion of perceptual experience. The paper is to show that those experiments do not refute this assumption, and will suggest that the impression to the contrary is, ultimately, due to two factors: to misleading imagery and, above all, to mistaken translation from the technical idiom of empirical psychology into the plain English we use every day. This is to take the mystery out of what we shall see to constitute a pretty puzzle; it is to remind us just how careful we need to be when drawing conclusions from results of scientific psychology; and it is to bring out the virtues of methods commonly lumped together under the entirely misleading label of 'ordinary language philosophy', of methods far more useful than their common caricature would make one think.
