Smartphone use and daily cognitive failures: A critical examination using a daily diary approach with objective smartphone measures

While smartphones have brought many benefits and conveniences to users, there is continuing debate regarding their potential negative consequences on everyday cognition such as daily cognitive failures. A few cross-sectional studies have found positive associations between smartphone use and cognitive failures. However, several research gaps remain, such as the use of cross-sectional designs, confounds related to stable individual differences, the lack of validity in self-report measures of smartphone use, memory biases in retrospective self-reports, and the lack of differentiation between smartphone checking and smartphone screen time. To simultaneously address the aforementioned shortcomings, the current study examined the within-person associations between various objective indicators of smartphone use and daily cognitive failures using a 7-day daily diary study. Multilevel modelling revealed that smartphone checking, but not total smartphone screen time, predicted a greater occurrence of daily cognitive failures at the within-person level. Surprisingly, we also found negative within-person associations between smartphone screen time for social- and tools-related applications and daily cognitive failures, suggesting that some types of smartphone use may temporarily benefit one's cognitive functioning. This finding demonstrates the importance of studying the specific functions of smartphone use and their differential cognitive consequences, as well as highlights the complex relations between smartphone use and cognition.     

管仲和亚里士多德法治思想异同论

管仲和亚里士多德分别在古代中国和希腊大致同时提出了法治理论,旗帜鲜明地提倡法治反对人治。然而,由于对于法律与法治的不同理解,管仲的法治是君主用法律维护其统治的“以法治国”,亚里士多德的法治则是用良法规范社会的“依法治国”。两者的“法治”内涵虽然不同,但法治思想中的“法律至上”对我国的法治建设有所启示。     

Ophthalmological problems of the premature infant

Preterm infants are more likely than term infants to have significant abnormalities of all parts of the visual system leading to reduced vision. The most common problem is retinopathy of prematurity (ROP). The frequency and severity of this disorder is inversely related to gestational age. Damage ranges from minor to catastrophic. Preterm infants also have higher rates of amblyopia, strabismus, refractive error, and cortical visual impairment. The later problem is largely associated with neonatal brain injury. Years later, these children may develop glaucoma and retinal detachments.     

A preliminary scale for assessing attitudes toward homosexuals in the military

This paper reports a factor analytical study of responses to statements of attitudes concerning lesbians and gay men in the military by 72 23.4-yr.-old members of the U.S. Marine Corps Reserve. Using exploratory factor analysis with an oblique rotation four factors were found which accounted for 64.9% of the total common variance. A factor labeled Trust accounted for 40.6% of the common variance, Comfort accounted for 8.7%, Acceptance accounted for 8.2%, and the fourth factor, Threat, accounted for 7.5%. Cronbach a ranged from .63 to .78. Validity was .75 when scores were correlated with those on the Attitudes Toward Lesbians and Gay Men scale, supporting the 4-factor interpretation. It is recommended that additional factor analyses be performed to further investigate the validity of the four factors and that of the entire scale.     

Fierce Words: Repositionings of Caste and Devotion in Traditional rvaisnava Hindu Ethics

In the 13th and 14th centuries CE the ?rvaisnava Hindu community of south India struggled to integrate the traditional values of the older brahmanical hierarchical system with the devotional egalitarianism that had come to the fore with fresh force in the Tamil vernacular tradition in the 7^th and 8^th centuries and thereafter. One of the most vexed aspects of this integration pertained to caste, and whether devotionalism foreclosed a continuation of traditional caste distinctions: do divine love and grace mandate radical egalitarianism? ?rvaisnava theologians were divided on the issue, some more conservative, some more radical in their rhetoric about continuity and change. Yet, as this essay argues, none were willing to go to the extremes either of dismissing caste structures entirely or of entirely subordinating devotion to caste. New values were to take primary place, while old norms were to be reinterpreted and given new meanings. Analyzing well–known examples from the tradition they argued instead a balance between norms and exceptions, treating violations of caste as occasions to glorify the power of devotion but without predicting the end of caste altogether. Attention to this case sheds light on caste and devotion in the Hindu context, the nature of ethical debate in India, and consequently too ways in which rhetoric functions more widely in ethical analysis.     

Automatic attraction of attention to former targets in visual displays of letters

Shiffrin and Schneider (1977, Experiment 4d) reported that after consistent training in search for particular alphanumeric characters, presentation of one of these characters (former targets) as a distractor impeded detection of simultaneously presented current targets. Even if presented in an irrelevant display location, the former target appeared to attract attention. Here, we analyze weaknesses in the design of Experiment 4d and report four follow-up experiments ranging from a fairly close replication of the original multiframe experiment to a rather conventional single-frame search study. In each experiment, presentation of former targets consistently impeded detection of simultaneously presented current targets. The results suggest that automatic attention attraction to individual alphanumeric characters develops not only in the special experimental paradigm used by Shiffrin and Schneider, but also in standard visual search tasks. The fact that attention appeared to be attracted by shapes as complex as individual letters supports the assumption that simultaneously presented visual stimuli can be compared in parallel against memory representations of alphanumeric characters.     

Prescribing conventional antipsychotics at two Veterans Administration hospitals: are there geographical differences?

The medical records of 110 patients receiving conventional antipsychotics at two geographically distinct Veterans Administration hospitals (Syracuse, New York, and Omaha, Nebraska) were reviewed. The most common reasons for continuation of conventional antipsychotics were good response and patient or physician choice. Frequently, physicians did not discuss the reasons for continuing conventional antipsychotics or the availability of alternative therapies with their patients. Geographic differences in physicians' prescribing practices of conventional antipsychotics were apparent.     

Pubertal transition, stressful life events, and the emergence of gender differences in adolescent depressive symptoms

This study examined the role of both pubertal and social transitions in the emergence of gender differences in depressive symptoms during adolescence. This study generated the following findings: (a) Gender differences in depressive symptoms emerged during 8th grade and remained significant through 12th grade. (b) Pubertal status in 7th grade was related to adolescent depressive symptoms over time. (c) Early-maturing girls represented the group with the highest rate of depressive symptoms. (d) Depressive symptoms measured in 7th grade predicted subsequent symptom levels throughout the secondary school years. (e) Recent stressful life events were associated with increased depressive symptoms. (f) Early-maturing girls with higher levels of initial symptoms and more recent stressful life events were most likely to be depressed subsequently. The findings demonstrate the importance of the interaction between the pubertal transition and psychosocial factors in increasing adolescent vulnerability to depressive experiences.
