Religious Activity and Risk Behavior Among African American Adolescents: Concurrent and Developmental Effects

This study examines how religious activity is associated with risk behaviors, concurrently and developmentally among urban African American adolescents. Seven hundred and five African American youths were interviewed annually during high school. Retention rates for the study exceeded 90%. Frequency of religious activity, sexual intercourse, and alcohol, cigarette, and marijuana use were assessed at each wave. Growth curve analyses found negative concurrent associations between religious activity and each of the four risk behaviors. The developmental effects of religious activity varied by gender. Higher levels of religious activity in 9th grade predicted smaller increases in marijuana use among males and cigarette use among females. In addition, larger decreases in religious activity during high school were associated with greater increases in alcohol use among males and sexual intercourse among females. During high school, religious activity limits the development of certain types of risk behavior among African American youth, even after controlling for reciprocal effects.     

Creating activity schedules using Microsoft Powerpoint

We describe how PowerPoint presentation software can be used to create computer activity schedules to teach individuals with special needs. Presented are the steps involved in creating activity schedules with close-ended and open-ended activities, and for preparing schedules that include photos, sounds, text, and videos that can be used to occasion an individual's engagement in a variety of learning activities.     

Effects of the Novel Acetylcholinesterase InhibitorN-Octyl-1,2,3,4-tetrahydro-9-aminoacridine on Locomotor Activity and Avoidance Learning in Mice

The acetylcholinesterase reversible inhibitorN-octyl-1,2,3,4-tetrahydro-9-aminoacridine (THA-C8) is a new synthesized derivative of tacrine (THA) characterized by an alkyl chain in the molecular structure which ameliorates the penetrability of the compound into the central nervous system. THA-C8 (0.1–5 mg/kg) significantly reduced spontaneous locomotor activity in CD1 mice at a dose of 3 mg/kg. Moreover, THA-C8 (0.2–2 mg/kg) significantly improved shuttle-box avoidance acquisition at doses (0.25, 0.3, 1 mg/kg) not affecting locomotion and that are much lower than the doses reported to be effective for THA in animal models. From the data reported it seems that the new compound could be interesting for therapeutic purposes.     

自我信息的反应抑制优势：来自神经振荡的证据

为探明个体对自我信息的反应抑制神经机制,记录了被试在完成面孔识别的停止信号任务时的脑电信号。神经振荡结果显示,反应任务中,加工自我面孔引发了更大的同步化δ节律和去同步化β节律;停止任务中,自我面孔引发了更大的去同步化β节律,特别在大脑前额区和中线上。表明,自我信息的反应抑制优势发生在抑制控制阶段,在于增强的β节律的去同步化促进了运动准备,提高了后续的动作抑制的速度。     

当代大学生性道德价值取向调查研究

本研究以信度和效度较高的自编问卷,通过对我国经济发达不同地区的九所不同类别高校1673名大学生进行调查,揭示:不同类别大学生间的性道德观念存在显著差异;不过,大学生总体上对性道德持肯定态度,对性行为道德、边缘性行为道德的认可程度较高,对独自性行为存在矛盾心态,对同性恋倾向持否定态度。本研究提出:性行为道德由"贞操、感情、自愿、责任、忠诚"五因素构成;边缘性行为道德由"感情、自愿、责任"三因素构成。     

不同年级学生自然阅读过程信息加工活动特点研究

探讨不同年级学生自然阅读过程的信息加工活动特点,包括两个实验。实验１结果表明,低年级学生自然阅读后再复述文章时需要重读原文的时间比高年级学生要多,据此初步推知,低年级学生自然阅读过程可能主要是单一的语言解码信息加工活动,高年级学生自然阅读过程可能同时进行了语言解码与组织连贯的信息加工活动,以后者为主。实验２比较不同年级的学生在自然阅读、理解任务阅读与记忆任务阅读三种情况下对文章信息保持的效果,结果     

The Role of Rape Myth Acceptance and Psychopathy in Sexual Assault Perpetration

Perpetrators of sexual aggression consistently report higher scores on measures of psychopathy and acceptance of rape myths relative to nonperpetrators. However, less is known about psychopathy among nonincarcerated individuals and the relation between the two constructs has not been empirically examined among college perpetrators. To address this gap, both constructs were measured in a sample (N?=?308) of college men. Rape myth acceptance was positively correlated with psychopathy, and perpetrators scored higher on both constructs. Myths transferring responsibility to victims were related to Factor 1 psychopathy (i.e., callous and manipulative traits). The myth that “rape is trivial” was associated with Factor 1 and Factor 2 (i.e., impulsive and antisocial behavior), possibly suggesting that this myth is related to a larger tendency to excuse aggressive behavior. Although both constructs distinguished perpetrators when considered individually, rape myth acceptance did not explain unique variance in the presence of psychopathy.     

Perceived stress and everyday memory complaints among older adult women

Abstract

Memory complaints among older adults are often influenced by depression and anxiety, but the association of stress to memory complaints has received little attention. We examined the associations of perceived stress, life events, and activity level to everyday memory complaints among healthy older women, while controlling for the influence of depression and anxiety. Participants (N=54) completed self-report questionnaires on memory complaints, perceived stress, recent life events, activity level, depression, and anxiety. Partial correlation analyses indicated that higher levels of perceived stress were associated with higher levels of memory complaints when controlling for the influence of depression and anxiety, but that life events and activity level were not related to memory complaints. This study highlights that perceived stress, like depression and anxiety, is a psychological factor that influences the appraisal of cognitive ability; however, larger and more heterogeneous samples will be needed to better understand the multifactorial nature of memory complaints in older adulthood.
