Prenatal tobacco exposure: developmental outcomes in the neonatal period

Smoking during pregnancy is a persistent public health problem that has been linked to later adverse outcomes. The neonatal period--the first month of life--carries substantial developmental change in regulatory skills and is the period when tobacco metabolites are cleared physiologically. Studies to date mostly have used cross-sectional designs that limit characterizing potential impacts of prenatal tobacco exposure on the development of key self-regulatory processes and cannot disentangle short-term withdrawal effects from residual exposure-related impacts. In this study, pregnant participants (N = 304) were recruited prospectively during pregnancy, and smoking was measured at multiple time points, with both self-report and biochemical measures. Neonatal attention, irritable reactivity, and stress dysregulation were examined longitudinally at three time points during the first month of life, and physical growth indices were measured at birth. Tobacco-exposed infants showed significantly poorer attention skills after birth, and the magnitude of the difference between exposed and nonexposed groups attenuated across the neonatal period. In contrast, exposure-related differences in irritable reactivity largely were not evident across the 1st month of life, differing marginally at 4 weeks of age only. Third-trimester smoking was associated with pervasive, deleterious, dose–response impacts on physical growth measured at birth, whereas nearly all smoking indicators throughout pregnancy predicted level and growth rates of early attention. The observed neonatal pattern is consistent with the neurobiology of tobacco on the developing nervous system and fits with developmental vulnerabilities observed later in life.     

Examining children in English High Courts with and without implementation of reforms authorized in Section 28 of the Youth Justice and Criminal Evidence Act

This study examined whether the implementation of Section 28 of the Youth Justice and Criminal Evidence Act (1999) improved lawyers' questioning strategies when examining child witnesses in England. The government's Section 28 pilot study involved judges holding Ground Rules Hearings, during which restrictions and limitations were placed on the duration, content, and manner of questions to be asked. Afterwards, children's cross‐examinations were pre‐recorded and later played as part of their evidence at trial. The current study compared cases involving 6‐ to 15‐year‐old alleged victims of sexual abuse in which Section 28 was (n = 43) and was not (n = 44) implemented. Defence lawyers in Section 28 cases asked significantly fewer suggestive questions and more option‐posing questions than defence lawyers in Nonsection 28 cases. Younger children complied more with defence lawyers' suggestive questions. Ground Rules Hearings improved lawyers' questioning strategies, regardless of the case's involvement in the Section 28 pilot study.

Conservative protestants and engagement with sexual minorities living with HIV: the role of disgust and recategorizing contact

Conservative Protestants in the United States have historically distanced themselves from gay men, lesbians, and transgender persons living with HIV based largely on fears of moral contamination which are propagated by disgust. We argue how disgust can implicitly reify social divides that engender condemnation and subjugation. However, we will propose that it is achievable to safeguard the traditional tenets of sexuality and gender among conservative Protestants and actively oppose misapplications of those tenets to exclude persons living with HIV. We will support our thesis by describing the work of a medical clinic founded on conservative Protestant ideology that serves hijras and kotis living with HIV in India. We will introduce how applications of recategorizing contact, cognitive consistency, and cultural scaffolding are formative in maintaining one’s ideological integrity without enacting exclusion based on fear and disgust.     

The influence of peers on young adult substance use.

Data collected from 294 young adults, ages 19 to 25, and both a same- and an opposite-gender best friend or mate across 3 annual assessments were analyzed to examine the similarity to and influence of the peer on the young adult's substance use. The authors found similarity across time between both peers and the young adult in cigarette use, alcohol use, binge drinking, and, in most cases, marijuana use. In prospective analyses, peer use predicted young adult cigarette use, binge drinking, and problem use by the young adults. Results were generally consistent across gender and for both same- and opposite-gender peers. Findings emphasize peer influence contribution to young adult substance use and suggest the design of interventions that involve both young adults and their peers.     

Memory for autobiographical facts and events: a comparison of women reporting childhood sexual abuse and non‐abused controls

Although there is evidence that many adult survivors of childhood sexual abuse (CSA) have a period when they forget their abuse, existing research is equivocal about whether such individuals show other autobiographical memory impairments. The present study addressed some of the sampling and measurement problems apparent in previous studies and compared 74 women reporting a history of CSA with 60 non‐abused controls on their ability to recall facts and events from childhood. The results showed that the CSA group did not differ from the controls in the quality of their memories for autobiographical incidents. However, they were significantly less able than controls to recall specific facts about their personal history, such as significant addresses and names of significant individuals, after controlling for educational level, depression and childhood address changes. CSA group participants reporting a period of abuse forgetting appeared more impaired than those with continuous abuse memories in their recall of personal semantic facts, but were similar in their recall of autobiographical incidents. The findings suggest that experiencing a period of abuse forgetting is a more influential factor in predicting the ability to recall personal semantic facts than abuse status alone.

The influence of ethnicity,social class,and context on judgments about U.S. women

In 2 studies, the authors investigated impression formation as influenced by category-based stereotypes associated with ethnicity and social class. The participants in Study I made judgments about 1 target woman, described as interested in running for office in the Parent Teacher Organization (PTO) of her children's school. The hypothetical woman was presented to the respondents along with her photograph and information about her ethnic background (Anglo-Saxon, Latina, or Jewish) and occupation (middle class or working class). In Study 2, the authors changed the context and presented a younger target woman (also varied by ethnicity and social class) to the respondents as the new girlfriend of their older brother or cousin. In both studies, judgments were assessed by the participants' responses to 45 bipolar adjectives that, in each case, yielded 8 component factors. In both hypothetical contexts, social class was a powerful trigger for a variety of negative expectations: With respect to ethnicity, the Latina women were judged to be more unsuitable for the job of PTO vice president than were the Anglo-Saxon or Jewish women. The authors discussed potential psychological and social consequences of such category-based judgments.     

Self-esteem in schizophrenia: relationships between self-evaluation,family attitudes,and symptomatology

Participants with schizophrenia (N = 59) were assessed on self-evaluation, symptomatology, and positive and negative affect (expressed emotion) from significant others. An interview-based measure of self-evaluation was used and two independent dimensions of self-esteem were derived: negative and positive evaluation of self. As predicted, negative self-evaluation was strongly associated with positive symptoms, a more critical attitude from family members was associated with greater negative self-evaluation, and analyses supported a model whereby the impact of criticism on patients' positive symptoms was mediated by its association with negative self-evaluation. The interview-based method of self-esteem assessment was found to be superior to the questionnaire because its predictive effects remained after depressed mood was accounted for.     

Interviewee coaching, preparation strategies, and response strategies in relation to performance in situational employment interviews: an extension of Maurer, Solamon, and Troxtel (1998)

Voluntary attendance at an interview coaching session was positively related to situational interview performance, controlling for job knowledge, motivation to do well, race, and sex of 213 candidates applying for promotion into several police and fire department jobs in a large city. Discrete preparation strategies (e.g., participation in study groups, participation in role-playing) were related to participation in coaching and also were related to interview performance beyond what could be accounted for by coaching participation, shedding some light on the potential efficacy of specific preparation strategies for enhancing success in situational interviews. Most notably, coaching attendance and preparation by interviewees were positively associated with a tendency to use strategies in the interview that enhanced the organization of interviewees' answers, and this organization was positively associated with performance in the interview.     

Distinguishing common and task-specific processes in word identification: a matter of some moment?

The same 500 words were presented in 6 different word identification tasks (Experiment 1: lexical decision, semantic categorization, and 3 speeded naming tasks; Experiment 2: delayed naming). Reaction time (RT) distributions were estimated for each task and analyses tested for the effects of word frequency and animacy on various parameters of the RT distribution. Low frequency words yielded more skewed distributions than high frequency words in all tasks except delayed naming. The differential skew was most marked for tasks that required lexical discrimination. The semantic categorization task yielded highly skewed distributions for all words, but the word frequency effect was due to shifts in the location of the RT distributions rather than changes in skew. The results are used to evaluate the relative contributions of a common lexical access process and task-specific processes to performance in lexical discrimination and naming tasks.
