Repetition priming across the adult lifespan--the long and short of it

Previous reports suggest that repetition priming (i.e., enhanced processing of a stimulus after experience with that stimulus) is long lasting and impervious to the effects of age, in contrast to the pattern found with explicit memory. However, the nature of repetition priming in aged individuals remains unclear, as conflicting findings have also been reported. We used a longitudinal design to examine how repetition priming is affected by multiple stimulus repetitions (three presentations) and different delay intervals (no delay, 1 day, 1 week, and 1 month) in young adults, as well as in two groups of aging adults (young-elderly and old-elderly). Our findings extend previous reports that priming is long lasting, even when 1 month intervenes between the initial experience with an item and the subsequent priming test of that item (Cave, 1997), and is relatively impervious to the effects of age (Mitchell, et al., 1990). In addition, a more detailed characterization of priming and the effects of aging was revealed. Although priming is long lasting, remaining significant even at the month delay for all groups, it did decline over time and the rate of that decline differed with age. Both young-elderly and old-elderly groups showed a marked drop-off at 1 day, whereas young adults did not show a decline until 1 week. All groups benefited from multiple repetitions; however, this benefit disappeared at the month delay (in contrast to recognition memory, where the benefit remained significant). These findings support the assertion that repetition priming and explicit memory reflect the operation of distinct systems, and that these systems may undergo different rates of change in aging.     

Even with the Best of Intentions: Paternal Involvement and the Theory of Planned Behavior

Implicit in much of the fatherhood discourse is the assumption that if fathers want to take an active role in their children's lives, they could and would do so. While research has highlighted the factors associated with fathers' involvement, very few, if any, of these studies have been guided by a theory that accounts for both fathers' involvement intentions and their ability to follow through on those intentions. The theory of planned behavior and its emphasis on attitudes, the beliefs of significant others, and whether one has control over engaging in behavior is a conceptual fit to respond to questions related to the complex nature of paternal involvement. Using data from the Fragile Families and Child Well‐being Study, the purpose of this study was to test the utility of the theory of planned behavior in predicting fathers' involvement intentions and reports of involvement. The results revealed that the theory of planned behavior can be useful in examining paternal involvement and should be used in future research to enhance the fatherhood literature.     

A survey of smoking status and cancer risk perceptions among participants attending a hospital-based head and neck screening program

Abstract

Screening for head and neck cancer is underutilized. Given that lack of knowledge of the risk factors may partially account for screening underutilization. we surveyed subjective risk and knowledge of risk factors for head and neck cancer among 124 individuals who attended a free. hospital-based head and neck cancer screening. Few participants were current smokers. Most attendees perceived their risk as similar to others of their age and sex. Personal health habits comprised almost all of the risk-decreasing factors, yet less than half of the risk-increasing factors. generated. Personal habits were less frequently endorsed than factors such as pollution and heredity. Those who mentioned a risk behavior, or a family cancer history, reported higher subjective risk. Those who mentioned a personal health habit reported lower subjective risk. Results highlight needed efforts to increase screening among high-risk individuals through targeted education messages.     

Social-cognitive processes as moderators of a couple-focused group intervention for women with early stage breast cancer.

OBJECTIVE: The purpose was to examine whether social-cognitive variables would moderate the efficacy of a couple-focused group intervention (CG) for women diagnosed with early stage breast cancer. DESIGN: Participants (N = 238) were randomly assigned to 6 sessions of a couple-focused group versus usual care. Intent to treat growth curve modeling analyses indicated that emotional expression and emotional processing moderated CG effects on depression. MAIN OUTCOME MEASURES: The primary outcome measures for this study were psychological distress and psychological well-being. RESULTS: Treatment attrition analyses separating out participants assigned to but not attending CG indicated that emotional expression, emotional processing, and protective buffering moderated the effects of CG among those who attended CG with the most consistent effects noted for emotional processing on indicators of distress and well-being. CONCLUSION: The CG intervention may be more effective for patients who begin the group experience using emotional approach coping strategies to deal with cancer.     

Contextual Themes in Career Decision Making of Female Clients Who Indicate Depression

Difficulties concerning female counseling center clients' career decision making were explored in this qualitative study. The authors reviewed counseling intake and progress notes of 18 female students who sought counseling services at a university counseling center and who presented career concerns and reported feeling depressed. Most women in this study described their career decision‐making difficulties in the context of relationships with their parents or significant others. Both external (i.e., family relationships, family and culture, and relationships with significant others) and internal (i.e., developmental, developmental and mental health issues, and skill deficits) conditions emerged as significantly affecting these women's career decision‐making process.     

Impulsivity Symptoms as Core to the Developmental Externalizing Spectrum

Impulsivity is posited to be a key part of the externalizing spectrum during childhood, but this idea has received minimal empirical attention. The goal of the present investigation was to utilize network analysis to determine whether behavioral impulsivity symptoms are key components of the externalizing network across several developmental periods from preschool into adolescence. Participants were 109 preschoolers (64 % male) ages 3 to 6, 237 children (59 % male) ages 6 to 9, 372 children (59 % male) ages 10 to 13, and 357 adolescents (59 % male) ages 13 to 17 and their parents. Parents completed ratings of Attention-Deficit/Hyperactivity Disorder (ADHD) and Oppositional Defiant Disorder (ODD) symptoms on a well-validated rating scale. Network analyses indicated that ADHD and ODD were somewhat differentiated in preschool, becoming united by behavioral impulsivity symptoms during early childhood, and then differentiating into inattention versus externalizing clusters later during childhood and in adolescence. Behavioral impulsivity symptoms were core to the externalizing spectrum across most developmental periods, but core inattentive and ODD symptoms were also identified in line with progressive differentiation. These results suggest the increasing importance of impulsivity symptoms across development, explaining externalizing comorbidity and potentially serving as a viable target for childhood interventions for externalizing problems.     

An Examination of the Factor,Convergent, and Discriminant Validity of the Behavioral Inhibition System and Behavioral Activation System Scales

The Behavioral Inhibition System and Behavioral Activation System Scales (BIS/BAS scales) are the most widely used measures designed to assess Gray’s Reinforcement Sensitivity Theory. However, questions remain regarding its factor, convergent, and discriminant validity. We assessed these properties in two samples of undergraduates (N = 723, N = 103). In Study 1, confirmatory factor analysis supported previous findings that suggested removal of several items, resulting in acceptable fit for a four-factor model. Convergent and discriminant validity were assessed for the original and revised scales. In Study 2, a public speaking task was used to assess validity of the scales in reference to positive/negative affect. Convergent and discriminant validity for the revised scales were not substantially different from the original scales. We suggest that future researchers should consider the use of the revised measure we describe. We also suggest that the creation of a revised BIS/BAS scale using new items may be warranted.
