Computational Evidence for the Subitizing Phenomenon as an Emergent Property of the Human Cognitive Architecture

A computational modeling approach was used to test one possible explanation for the limited capacity of the subitizing phenomenon. Most existing models of this phenomenon associate the subitizing span with an assumed structural limitation of the human information processing system. In contrast, we show how this limit might emerge as the combinatorics of the space of enumeration problems interacts with the human cognitive architecture in the context of an enumeration task. Subitizing‐like behavior was generated in two different models of enumeration, one based on the ACT‐R cognitive architecture and the other based on the principles of parallel distributed processing (PDP). Our results provide good qualitative fits to results obtained in a variety of empirical studies.     

Behaviors of ADHD and Peer Relationship Difficulties in Chinese and American Youths: Role of Co-Occurring Behaviors of Depression and Anxiety

Abstract

The co-occurrence of behaviors of attention-deficit/hyperactivity disorder (ADHD) with behaviors of anxiety or behaviors of depression is the norm, but little is known on how the co-occurrence accounted for youths’ peer relations. The authors report results on difficult peer relations in relation to behaviors of ADHD, co-occurring behaviors of depression, and behaviors of anxiety from three studies on 862 youths in China and in the United States. Study 1 included 313 ethnically and socioeconomically diverse American youths; Study 2 included 250 youths who were adopted out of Chinese orphanages by American parents; and Study 3 included 299 youths from Beijing, China. Data on difficult peer relations and behaviors of ADHD, depression, and anxiety were collected with the third edition of Behavior Assessment System for Children-Self Report of Personality. In all three studies, each type of problems alone significantly predicted difficult peer relations, but behaviors of ADHD were not significant when co-occurring behaviors of depression or co-occurring behaviors of anxiety were considered. Despite that the youths in our study had different cultural and personal backgrounds, there was no evidence that behaviors of ADHD were detrimental to youths’ peer relations when behaviors of depression or anxiety were considered. Implications for intervention were discussed.     

Death in the new age

Modern death is characterized by secularization, and the related features of medical‐ization, privatization and individualism, and is increasingly criticized from an expressivist position. This is the context in which a considerable volume of New Age writing on death and dying has emerged. The article explores New Age concepts of the soul and of reincarnation, the basis for these beliefs and the effect they have on care of the dying, the willingness of New Age carers to let the dying person be him or herself, and New Age theodicies. It is concluded that the New Age concern with the soul of the dying represents a significant attempt to reverse the secularization of death, though the success of this endeavour may be undermined by emphasis on the variety of personal experience and meaning.     

The role of culture and traditions in how young children’s identities are constructed

ABSTRACT

This article explores how cultures and traditions influence the construction of young children’s identities. Identity is conceptualised as a constantly changing narrative based on how an individual sees him or herself and how s/he is perceived. We all have multiple, intersecting identities. Different meanings of culture are discussed, highlighting norms and values, ‘culture-as-the-arts’, and space for growth. Primary and secondary socialisation is emphasised, recognising the influence factors such as gender, race, class and religion. The effect of the home and of the macro-culture and different micro-cultures and traditions is considered. In relation to children’s spirituality, trusting relationships and hospitable environments, and the need to counter messages given by an individualistic and consumerist macro-culture are highlighted. An apprenticeship approach is advocated, where adults encourage questioning and strive to maintain children’s sense of agency, with a gradual transfer of power as children become older and/or more confident. It is suggested that researchers and practitioners should take more account of external factors such as gender, race and class in relation to children’s spirituality.
