Age-related changes in word retrieval vary by self-reported anxiety but not depression symptoms

Tip-of-the-tongue states (TOTs) are known to increase in frequency across adulthood, but there is wide variability in older adults’ TOT rates, suggesting that individual difference factors contribute to TOT incidence. We investigated the role of affect by examining the relationship between self-reported anxiety and depression symptoms and the frequency of TOTs during a laboratory task. Participants were young, middle-aged and older adults in a population-based sample of adults aged 18–87. Increased anxiety was associated with fewer TOTs for the middle-aged group but more TOTs for the older adult group. There was no relationship between anxiety and TOTs for younger adults and no relationships between depression symptoms and TOT incidence for any age group. We discuss our results in terms of attentional control theory, which provides an explanation of how age may affect the relationship between anxiety and TOTs.     

Meta‐analysis of behavioral self‐management techniques used by students with disabilities in inclusive settings

This comprehensive review synthesizes findings from 29 studies in which students with disabilities utilized behavioral self‐management techniques in inclusive settings. Findings suggest that consistent with 2 earlier reviews of these types of studies, most behavioral self‐management techniques continue to be adaptable in inclusive settings with moderate to strong efficacy. This review identifies strengths as well common limitations of the studies, provides recommendations for future research and practice, and includes behavioral self‐management resources.     

In Her Own Words: Semi-structured Interviews of Women Veterans Who Experienced Military Sexual Assault

Twenty-one female veterans volunteered to talk about 29 events of military sexual assault (MSA) via semi-structured interviews covering pre-military abuse, during and immediately after the assault and reactions post-assault. The 14 who reported on-going abuse in childhood, also experienced multiple events of MSA. Common themes revealed that most events happened at night (52% specifically referenced night, while 69% most likely occurred at night), 24% in a car, and 24% while the victim was on duty. MSA was associated with a low use of weapons (17% with knives or guns) but a high use (52%) of physical violence (e.g., hitting, choking) and intimidation (59%). 69% knew their perpetrator prior to the assault and 12 of them (60%) were superiors. 34.5% of the perpetrators and 24% of the victims were drinking alcohol prior to the assault. 27.5% reported the MSA; however, 52% had to continue to interact with the perpetrator as part of her job. 67% reported being pregnant or seriously injured as a result of the MSA; however, only 28% received help. 71% disclosed that they had suicidal ideation 14% made suicide attempts while on active duty, and 38% made a suicide attempt some time in their lifetime post-MSA. 52% said the MSA lead to an early discharge from the military. 76% stated MSA interfered with their ability to have an intimate relationship. All participants graduated Warrior Renew sexual trauma treatment and reported positive responses. Although this is a small sample, findings may help generate hypotheses for larger scale studies.     

Fear Develops to the Conditioned Stimulus and to the Context during Classical Eyeblink Conditioning in Rats

In classical eyeblink conditioning, non-specific emotional responses to the aversive shock unconditioned stimulus (US), which are presumed to coincide with the development of fear, occur early in conditioning and precede the emergence of eyeblink responses. This two-process learning model was examined by concurrently measuring fear and eyeblink conditioning in the freely moving rat. Freezing served as an index of fear in animals and was measured during the inter-trial intervals in the training context and during a tone conditioned stimulus (CS) presented in a novel context. Animals that received CS-US pairings exhibited elevated levels of fear to the context and CS early in training that decreased over sessions, while eyeblink conditioned responses (CRs) developed gradually during acquisition and decreased during extinction. Random CS-US presentations produced a similar pattern of fear responses to the context and CS as paired presentations despite low eyeblink CR percentages, indicating that fear responding was decreased independent of high levels of learned eyeblink responding. The results of paired training were consistent with two-process models of conditioning that postulate that early emotional responding facilitates subsequent motor learning, but measures from random control animals demonstrate that partial CS-US contingencies produce decrements in fear despite low levels of eyeblink CRs. These findings suggest a relationship between CS-US contingency and fear levels during eyeblink conditioning, and may serve to clarify further the role that fear conditioning plays in this simple paradigm.     

Awareness and Preferences Regarding <Emphasis Type="Italic">BRCA1/2</Emphasis> Genetic Counseling and Testing Among Latinas and Non-Latina White Women at Increased Risk for Hereditary Breast and Ovarian Cancer

This study was an investigation of awareness, cognitions, and psychosocial and educational needs related to genetic counseling and testing among Latinas and non-Latina whites at increased risk for having a BRCA1/2 mutation. Sixty-three Latina and eighty-four non-Latina white women completed telephone surveys employing a mixture of quantitative and qualitative questions assessing awareness, benefits, risks, barriers, and genetic counseling communication preferences regarding BRCA1/2 testing. Among participants who had not previously had genetic counseling/testing, 56.9% of Latinas (29/51) and 34.8% of non-Latina white participants (24/69) were unaware of the availability of BRCA1/2 testing. In multivariate logistic regression analysis, Latina ethnicity was the only statistically significant independent factor associated with lack of awareness (OR = 0.42; 95% CI = 0.19–0.35). No appreciable differences were noted between ethnic groups regarding perceived benefits of BRCA1/2 testing or desired genetic counseling topics. These findings underscore the importance of increasing awareness of cancer genetic counseling and genetic testing among both Latina and non-Latina white populations.     

Speech perception as categorization

Speech perception (SP) most commonly refers to the perceptual mapping from the highly variable acoustic speech signal to a linguistic representation, whether it be phonemes, diphones, syllables, or words. This is an example of categorization, in that potentially discriminable speech sounds are assigned to functionally equivalent classes. In this tutorial, we present some of the main challenges to our understanding of the categorization of speech sounds and the conceptualization of SP that has resulted from these challenges. We focus here on issues and experiments that define open research questions relevant to phoneme categorization, arguing that SP is best understood as perceptual categorization, a position that places SP in direct contact with research from other areas of perception and cognition.     

Stress management interventions for HIV+ adults: a meta-analysis of randomized controlled trials, 1989 to 2006.

OBJECTIVE: Numerous studies document that stress accelerates disease processes in a variety of diseases including HIV. As a result, investigators have developed and evaluated interventions to reduce stress as a means to improve health among persons living with HIV. Therefore, the current meta-analysis examines the impact of stress-management interventions at improving psychological, immunological, hormonal, and other behavioral health outcomes among HIV+ adults. DESIGN: This meta-analytic review integrated the results of 35 randomized controlled trials examining the efficacy of 46 separate stress management interventions for HIV+ adults (N=3,077). MAIN OUTCOME MEASURES: Effect sizes were calculated for stress processes (coping and social support), psychological/psychosocial (anxiety, depression, distress, and quality of life), immunological (CD4+ counts and viral load), hormonal (cortisol, dehydroepiandrosterone sulfate [DHEA-S], cortisol/DHEA-S ratio, and testosterone) and other behavioral health outcomes (fatigue). RESULTS: Compared to controls, stress-management interventions reduce anxiety, depression, distress, and fatigue and improve quality of life (d+s=0.16 to 0.38). Stress-management interventions do not appear to improve CD4+ counts, viral load, or hormonal outcomes compared with controls. CONCLUSION: Overall, stress-management interventions for HIV+ adults significantly improve mental health and quality of life but do not alter immunological or hormonal processes. The absence of immunological or hormonal benefits may reflect the studies' limited assessment period (measured typically within 1-week postintervention), participants' advanced stage of HIV (HIV+ status known for an average of 5 years), and/or sample characteristics (predominately male and White participants). Future research might test these hypotheses and refine our understanding of stress processes and their amelioration.
