Encoding instructions and stimulus presentation in local environmental context-dependent memory studies

Murnane and Phelps (1993) recommend word pair presentations in local environmental context (EC) studies to prevent associations being formed between successively presented items and their ECs and a consequent reduction in the EC effect. Two experiments were conducted to assess the veracity of this assumption. In Experiment 1, participants memorised single words or word pairs, or categorised them as natural or man made. Their free recall protocols were examined to assess any associations established between successively presented items. Fewest associations were observed when the item-specific encoding task (i.e., natural or man made categorisation of word referents) was applied to single words. These findings were examined further in Experiment 2, where the influence of encoding instructions and stimulus presentation on local EC dependent recognition memory was examined. Consistent with recognition dual-process signal detection model predictions and findings (e.g., Macken, 2002; Parks & Yonelinas, 2008), recollection sensitivity, but not familiarity sensitivity, was found to be local EC dependent. However, local EC dependent recognition was observed only after item-specific encoding instructions, irrespective of stimulus presentation. These findings and the existing literature suggest that the use of single word presentations and item-specific encoding enhances local EC dependent recognition.     

Hearing living symbols and nonliving icons: Category specificities in the cognitive processing of environmental sounds

The neurocognitive processing of environmental sounds and linguistic stimuli shares common semantic resources and can lead to the activation of motor programs for the generation of the passively heard sound or speech. We investigated the extent to which the cognition of environmental sounds, like that of language, relies on symbolic mental representations independent of the acoustic input. In a hierarchical sorting task, we found that evaluation of nonliving sounds is consistently biased toward a focus on acoustical information. However, the evaluation of living sounds focuses spontaneously on sound-independent semantic information, but can rely on acoustical information after exposure to a context consisting of nonliving sounds. We interpret these results as support for a robust iconic processing strategy for nonliving sounds and a flexible symbolic processing strategy for living sounds.     

Is it even worth it? The effect of loss prospects in the outcome distribution of a public goods dilemma

Contributions to public goods are premised on the expectation that the collective will realize benefit in excess of the value of required contributions. However, past research has focused on public goods of fixed and known value, for which the added value of the produced public good is obvious. Research has largely ignored public goods whose eventual value is uncertain at the time contribution decisions are made. Two studies explored the effects of outcome variance on individuals’ contributions to a public good and their reasons for contributing. Contributions were negatively affected by loss prospects in the distribution of possible outcomes. Further, loss prospects directly discouraged contributions because of loss aversion, and indirectly discouraged contributions by fueling fears that others would not contribute. The negative effects of loss prospects were stronger when social uncertainty was low. Implications for social dilemma research and the effective management of collective action are discussed.     

Correlates of household smoking bans in low-income families of children with and without asthma

Exposure to secondhand smoke (SHS) harms all children's health, especially children with asthma. Yet, children with asthma are as likely to live with smokers as healthy children. Household smoking bans are being advocated to reduce children's harm from SHS. To measure the effect of household smoking bans on child SHS exposure and to examine correlates of strict smoking bans in a low-income, diverse sample, 91 children with asthma were matched to 91 healthy children. All had at least one smoker living in their homes. Nicotine dosimeters, child cotinine assays, and maternal reports quantified child SHS exposures. Maternal reports of household smoking rules, behaviors, and beliefs, and other family characteristics were also gathered. The presence of a strict household smoking ban vastly reduced children's SHS exposures and was associated with fewer cigarettes smoked by the mother and by other family members, the belief that SHS was a personal health risk, having children with asthma, and living in a single-family home. Many children are exposed to high levels of SHS at home. Strict household smoking bans greatly decrease, but do not eliminate children's SHS exposure. Even in disadvantaged families, mutable factors were associated with strict smoking bans. Increased dissemination and use of established public health strategies are needed to reduce children's SHS exposures.     

A multi-factorial framework for understanding reckless driving—appraisal indicators and perceived environmental determinants

The current study adopted an approach, in which reckless driving is perceived as related to both personal and environmental factors. Young drivers (N = 295) reported on reckless driving related threat and challenge appraisals, their perceived control over reckless driving, their disregard for negative consequences of this specific behavior, positive feedback received on their driving, environmental driving-climate and negative driving modeling. The dependent measure was self-reported frequency of reckless driving. Findings indicated that challenge and self-efficacy appraisals, along with negative environmental influences were related to higher frequency of risky driving, whereas threat appraisals, as well as positive feedback, were related to a lower frequency of reckless driving. In addition, whereas for men, self-efficacy in driving strongly predicted reckless driving, disregard for negative consequences was an important predictor for women. The results are discussed in view of an evaluating process of personal cognitive-emotional resources and environmental support proposed by Lazarus. Recommendations are made regarding the potential effectiveness of using positive appeals in prevention interventions.     

Évaluer la satisfaction envers l’espace de travail : développement d’une échelle et première validation

Organizational space is a meaningful environment that can contribute to the well-being of the individual or lead to dissatisfaction and stress. The objective of this research is to develop a scale of satisfaction of employees toward their work place and test its factorial structure and internal validity. Two principal satisfaction factors have been isolated in an exploratory study carried out among 214 participants. A second-order factorial structure has been established in a cross-validation of the scale during a confirmatory study applied to a second sample of 261 participants. The internal consistency of the satisfaction dimensions, the adequacy of the measurement model to the data, and the stability of the factorial structure are proof of the good psychometric qualities of this scale.

Born to learn or born to win? Birth order effects on achievement goals

Given the widespread use and well-known consequences of achievement goals in different competence-relevant situations, it is important to gain a thorough understanding of how these differences in goal pursuit are formed. Using different analytic approaches, we show that birth order lies at the heart of people’s goal preferences as we consistently found that firstborns have developed a preference for mastery goals (which are based on self-referenced standards of competence), whereas secondborns have developed a preference for performance goals (which are based on other-referenced standards of competence). These findings may help explain why people differently define, experience, and respond to competence-relevant situations, including the workplace, the classroom, and the ball field.     

Mental Contamination in Obsessive-Compulsive Disorder: Associations With Contamination Symptoms and Treatment Response

The most common symptom of obsessive-compulsive disorder (OCD) is contamination fear. Feelings of contamination can be provoked through contact with a physical contaminant, referred to as contact contamination (CC), as well as in the absence of one, referred to as mental contamination (MC). Prior research indicates that CC and MC are distinct, and MC may interfere with treatment for CC. However, no study to date has examined how MC may be associated with responses to physical contaminants and treatment response for CC. This study examined the relationships between CC and MC in a sample of individuals with elevated contamination symptoms (N = 88), half of whom met diagnostic criteria for OCD. Participants engaged in three sessions of exposure and response prevention (ERP) for CC and completed self-report measures and behavioral tasks assessing CC and MC at pretreatment, posttreatment, and follow-up. As hypothesized, at pretreatment, MC was positively associated with reactivity to physical contaminants, even after participants washed their hands. ERP for CC was associated with unique changes in CC and MC across self-report and behavioral measures, and greater pretreatment MC predicted greater posttreatment CC, though this effect was evident in only one of two CC measures. Additionally, specificity analyses indicated changes in MC were independent of changes in disgust propensity, a related construct. Pretreatment disgust propensity also predicted treatment outcome, though the addition of pretreatment disgust propensity as a covariate reduced the relationship between pretreatment MC and posttreatment CC to nonsignificance. Results suggest MC plays an important role in the manifestation and treatment of CC symptoms and may represent a manifestation of disgust proneness. Theoretical and clinical implications are discussed.
