The Impact of Self-Affirmation on Health-Related Cognition and Health Behaviour: Issues and Prospects

In a recent paper (Harris & Epton, Social and Personality Psychology Compass, 2009; 3 , 962–978), we reviewed the evidence showing that self-affirming – the act of reflecting upon cherished values or attributes – can reduce resistance to health-risk information. In this companion paper, we extend the discussion of issues arising from that review and describe key questions for future research. Overall, we regard the picture emerging from this nascent literature as encouraging. Nevertheless, more needs to be discovered about how self-affirming achieves its effects and their limits. Despite lowering an important barrier to health behaviour change by reducing message resistance, there is currently only limited evidence that self-affirming changes subsequent health behaviour. We consider why. We also discuss issues to address in interventions involving self-affirmation and examine evidence that self-affirming alters relationships between variables. There is also scope for extending the range of samples, health information and health behaviours examined and for assessing more spontaneous self-affirmation.     

The development of infants’ use of property-poor sounds to individuate objects

There is evidence that infants as young as 4.5 months use property-rich but not property-poor sounds as the basis for individuating objects (Wilcox, Woods, Tuggy, & Napoli, 2006). The current research sought to identify the age at which infants demonstrate the capacity to use property-poor sounds. Using the task of Wilcox et al., infants aged 7 and 9 months were tested. The results revealed that 9- but not 7-month-olds demonstrated sensitivity to property-poor sounds (electronic tones) in an object individuation task. Additional results confirmed that the younger infants were sensitive to property-rich sounds (rattle sounds). These are the first positive results obtained with property-poor sounds in infants and lay the foundation for future research to identify the underlying basis for the developmental hierarchy favoring property-rich over property-poor sounds and possible mechanisms for change.     

Connecting Data to Action: How the Santa Cruz County Community Assessment Project Contributes to Better Outcomes for Youth

Community indicator projects have the potential to deliver new knowledge about the quality of life in local communities and drive actions to improve them (Phillips 2003; Holden Social Indicators Research 92:429–448, 2009; Memon and Johnstone 2008). However, the connection between the information produced by community indicator projects and the actions taken to improve conditions in communities remains under-researched (Holden Social Indicators Research 92:429–448, 2009; Hezri and Dovers Ecological Economics 60:86–99, 2006). This is because community indicator projects have mainly been conceptualized as producing information for action rather than as part of an action process (Memon and Johnstone 2008). This paper provides a case study of a community indicator project with an explicit plan to move beyond the data and into action. A review of one of the oldest community indicator projects in the United States, the Santa Cruz County Community Assessment Project (CAP) demonstrates how an action oriented community improvement cycle has contributed to measurable improvements for children and youth in one California County. The paper identifies key elements that were important for turning CAP data into local actions and concludes with lessons for community indicator practitioners and questions for future research.     

A multi-informant longitudinal study on the relationship between aggression, peer victimization, and dating status in adolescence

Adolescent peer-aggression has recently been considered from the evolutionary perspective of intrasexual competition for mates. We tested the hypothesis that peer-nominated physical aggression, indirect aggression, along with self-reported bullying behaviors at Time 1 would predict Time 2 dating status (one year later), and that Time 1 peer- and self-reported peer victimization would negatively predict Time 2 dating status. Participants were 310 adolescents who were in grades 6 through 9 (ages 11-14) at Time 1. Results showed that for both boys and girls, peer-nominated indirect aggression was predictive of dating one year later even when controlling for age, peer-rated attractiveness, and peer-perceived popularity, as well as initial dating status. For both sexes, self-reported peer victimization was negatively related to having a dating partner at Time 2. Findings are discussed within the framework of intrasexual competition.     

Inhibition of return for target discriminations: the effect of repeating discriminated and irrelevant stimulus dimensions

Inhibition of return (IOR) refers to slowed reaction times when a target repeats in the same location as a preceding stimulus. In four experiments, the participants were presented with two successive stimuli, S1 and S2. In Experiments 1 and 2, the participants made a speeded discrimination of the identity or orientation of both S1 and S2 (Experiment 1) or of S2 only (Experiment 2). An IOR effect occurred for the repetition of stimulus location, but a facilitatory effect occurred if the stimulus remained unchanged or if an overt response was repeated. In Experiments 3 and 4, the participants localized S1 and S2 (Experiment 3) or S2 only (Experiment 4) to the left or right of center. In this case, repeating the same stimulus had no effect: IOR occurred any time stimulus location repeated. These results demonstrate that the expression of IOR is modulated by the repetition of a target object, but only when the task requires the discrimination of that object; when no discrimination is required, IOR is unaffected.     

Visual attention and word recognition in stroop color naming: is word recognition "automatic"?

In Stroop color naming, color targets were accompanied by a color word or a color word plus a neutral word that reduces or "dilutes" the Stroop effect. Abrupt-onset cues called the focus of attention to one stimulus or another. Cuing influenced the size of the Stroop effect but never eliminated it. Unlike the Stroop effect itself, Stroop dilution from the neutral word could be eliminated, by cuing the color word. Focusing visual attention on the color word protected it from Stroop dilution; focusing visual attention on the neutral word did not prevent Stroop interference. Thus, spatial attention is a modulator, protecting visual data from crosstalk, but a word need not be the focus of visual attention to be recognized.     

Effects of a Perseverative Interest-Based Token Economy on Challenging and On-Task Behavior in a Child with Autism

We compared the effects of a token economy intervention that either did or did not include the perseverative interests of a 7-year-old boy with autism. An alternating treatment design revealed that the perseverative interest-based tokens were more effective at decreasing challenging behavior and increasing on-task behavior than tokens absent the perseverative interest during an early literacy activity. The beneficial effects were then replicated in the child’s classroom. The results suggest that perseverative interest-based tokens might enhance the effectiveness of interventions based on token economies.     

Personality moderates the interaction between positive and negative daily events predicting negative affect and stress

A 30-day diary study examined personality moderators (neuroticism and extraversion) of the interaction between positive and negative daily events predicting daily negative affect and night-time stress. Multilevel analyses revealed positive daily events buffered the effect of negative daily events on negative affect for individuals low in neuroticism and individuals high in extraversion, but not for individuals high in neuroticism or individuals low in extraversion. Positive daily events also buffered the effect of negative daily events on that night’s stress, but only for participants low in neuroticism. As such, this research linked today’s events to tonight’s stressfulness. This study advances our understanding of how neuroticism and extraversion influence within-person associations between positive and negative events predicting negative affect and stress.     

Parenting Behavior and Cognitions in a Community Sample of Mothers with and without Symptoms of Attention-deficit/Hyperactivity Disorder

Although attention-deficit/hyperactivity disorder (ADHD) in adults has recently emerged as an important area of research, little attention has been given to the family functioning of women with ADHD, particularly in their role as mothers. We examined parenting self-esteem, locus of control, and disciplinary styles in a community sample of mothers with varying levels of ADHD symptoms. Women with high levels of ADHD symptoms reported more occupational and psychiatric problems than women with lower levels of ADHD symptoms. They also reported lower parenting self-esteem, a more external parenting locus of control, and less effective disciplinary styles. The findings suggest that women with ADHD symptoms may face a number of difficulties within the parenting domain.
