Alexander Bain (1818–1903) is well known for his two influential textbooks, The senses and the intellect (1855) and The emotions and the will (1859). In comparison, Bain's Mind and body: The theories of their relation (1872) has been of limited interest to historians, and it is here where he presents one of the first neural network models. This paper addresses the historical foundations of Bain's neural network model and explores some of his primary influences. Additionally, this study addresses some of the reasons Bain's Mind and Body did not receive the historical notice his earlier works garnered.  相似文献

With the growing appreciation of the importance of early learning experiences for children's healthy development, attention to the cultivation and maintenance of a qualified workforce has steadily increased. Such a workforce must have not just the knowledge and skills related to child development and early learning, but also be linguistically and culturally prepared to meet the needs of an increasingly diverse child and family population. To ensure a highly qualified workforce, programs and policymakers must attend to both the “pipeline” through which new early childhood educators (ECEs) enter the workforce and the “pathways” by which ECEs work toward and obtain the necessary education and credentials for different roles within the field. In line with the aims of this special issue, this paper leverages the first‐person account style to describe barriers to and creative solutions for the development of practitioners in low‐resourced communities in Chicago, with the goal of informing practice and policy. We describe three prior and ongoing partnership programs between community‐based organizations and institutions of higher education, each tailored to support a unique population in the ECE pipeline on the pathway for increased educational attainment and credentialing. Each program is grounded in a specific community of Chicago, a diverse city with a sizable population of children raised in non‐English speaking homes. Each program addresses specific needs of the communities they serve, especially around the recruitment, retention, and promotion of bilingual ECEs. Program administrators and community members describe each programs’ goals, development, and key components unique to their target population as well as key takeaways. We conclude with an overview of critical components that we identified across these programs in order to create pathways for change within the workforce and the communities they serve.  相似文献

Psychological predictors of problem mobile phone use.   总被引:1,自引:0,他引:1  
Mobile phone use is banned or illegal under certain circumstances and in some jurisdictions. Nevertheless, some people still use their mobile phones despite recognized safety concerns, legislation, and informal bans. Drawing potential predictors from the addiction literature, this study sought to predict usage and, specifically, problematic mobile phone use from extraversion, self-esteem, neuroticism, gender, and age. To measure problem use, the Mobile Phone Problem Use Scale was devised and validated as a reliable self-report instrument, against the Addiction Potential Scale and overall mobile phone usage levels. Problem use was a function of age, extraversion, and low self-esteem, but not neuroticism. As extraverts are more likely to take risks, and young drivers feature prominently in automobile accidents, this study supports community concerns about mobile phone use, and identifies groups that should be targeted in any intervention campaigns.  相似文献

The relationship between co-occurring personality disorders and anxiety disorders (panic disorder with or without agoraphobia, social phobia, and generalized anxiety disorder) was examined, taking into account the effect of major depression. This article describes findings for 622 participants in the Harvard/Brown Anxiety Research Project, a longitudinal follow-up study of DSM-III-R-defined anxiety disorders. A total of 24% of participants had at least one personality disorder, with avoidant, obsessive compulsive, dependent, and borderline most common. Generalized anxiety disorder, social phobia, and major depression were positively associated with the occurrence of one or more personality disorders, whereas panic disorder with agoraphobia was not associated. Major depression was associated in particular with dependent, borderline, histrionic, and obsessive compulsive personality disorders and social phobia was associated with avoidant personality disorder. Whereas some of our findings confirm results from earlier studies, others are somewhat inconsistent with previous results and indicate the need for further investigation.  相似文献

Gene-environment interactions are presumed to shape human behavior during early development. However, no human research has demonstrated that such interactions lead to stable individual differences in fear responses. We tested this possibility by focusing on a polymorphism in the promoter region of the gene for the serotonin transporter (5-HTT). This polymorphism has been linked to many indices of serotonin activity. Specifically, we tested the hypothesis that an interaction between children's 5-HTT status and maternal reports of social support predicts inhibited behavior with unfamiliar peers in middle childhood. Results were consistent with this hypothesis: Children with the combination of the short 5-HTT allele and low social support had increased risk for behavioral inhibition in middle childhood.  相似文献

This study examined sex differences in body image change and its correlates over the course of a 12-week strength-training program. Participants were 28 men and 16 women (M age = 21.6, SD = 2.4) who completed pre- and post-intervention measures of body image (Body Areas Satisfaction Scale, Social Physique Anxiety Scale, and Drive for Muscularity Scale) and subjective and objective assessments of body fat, muscularity, and strength. They participated in a 12-week, 5-day/week full-body progressive resistance training program. Significant body image improvements were found for both sexes (p < .05). Correlates of body image change varied somewhat between the sexes. For men, body image improvements were correlated only with subjective physical changes. For women, body image improvements were correlated with subjective physical changes as well as objective increases in strength. These results suggest that although men and women derive body image improvements from strength training, they may benefit for different reasons.  相似文献

Muscle dysmorphia – a pathological preoccupation with muscularity – appears to be a form of body dysmorphic disorder (BDD) with a focus on muscularity. However, little is known about muscle dysmorphia in men with BDD, and no study has compared men with BDD who do and do not report muscle dysmorphia. To explore this issue, we reviewed the histories of 63 men with BDD; we compared those rated as having a history of muscle dysmorphia with those who had BDD but not muscle dysmorphia in several domains. The 14 men with muscle dysmorphia resembled the 49 comparison men in demographic features, BDD severity, delusionality, and number of non-muscle-related body parts of concern. However, those with muscle dysmorphia were more likely to have attempted suicide, had poorer quality of life, and had a higher frequency of any substance use disorder and anabolic steroid abuse. Thus, muscle dysmorphia was associated with greater psychopathology.  相似文献

The aim of this study was to investigate the toddler and preschool predictors of early peer social preference. Behavioral and social functioning were examined in a sample of children across the toddler and preschool years from parent and teacher observations. Kindergarten social behavior and peer social preference were assessed in the children's kindergarten classrooms using standard sociometric techniques. Results indicated that parent report of toddler externalizing behavior and teacher report of preschool problem behavior, as indexed by aggressive behavior, social skills, and emotional regulation, were predictive of peer liking in kindergarten. However, this relation was mediated by specific behaviors evidenced in the kindergarten classroom. For boys, overt aggression mediated these relations. For girls, sharing and engaging in sneaky behavior in kindergarten mediated the relation between preschool problem behaviors and peer status. These results indicate that specific behaviors displayed in the peer group account for the relation between early problem behavior and peer status. Moreover, these data point to the importance of considering gender when examining developmental trajectories and outcomes.  相似文献
