Odour and Proustian memory: reduction of context‐dependent forgetting and multiple forms of memory

In Experiment 1, the reintroduction of the same ambient odour (lemon or lavender) improved performance four weeks later in both free recall and recognition of a word list. This was a cross‐over design that allowed direct comparison between congruent and incongruent odour conditions. A further comparison with an additional group showed that memory was not improved by the presence of a different odour. Experiment 2 investigated the effect of two odour cues (lemon and lavender) in the same cross‐over design using three learning and memory tests: (1) free recall of a word list; (2) problem solving; and (3) spatial learning. While recall of the word list and spatial learning were best when the same odour was present at both learning and test, there was no such context‐dependent effect for the problem‐solving task. However, the presence of the lavender odour at test improved performance in the problem‐solving task, irrespective of the odour present at the first exposure. Thus although lavender had some effect on problem solving, we saw context‐dependent retrieval only in free recall and spatial learning. We discuss the implications of this dissociation.

Exploring the relationship between secondary traumatic stress,professional identity and career factors for counsellors

This study used a correlational research design to explore the relationship between secondary traumatic stress, counsellor professional identity and career factors, including work setting and amount of counselling experience, among counsellor practitioners. A sample of 1,218 counsellors completed an online survey including the Secondary Traumatic Stress Scale (STSS), Professional Identity Scale in Counseling and career factors. Career factors included context of work environments including years of experience, licence status, type of practice and work setting. Multiple regression analysis with forward selection demonstrated that, out of all the variables, professional identity emerged as the best predictor of secondary traumatic stress. One-way ANOVA showed significant group differences in the level of counsellors' secondary traumatic stress based on work setting, level of experience, type of practice and gender. Discussion explores how career and personal factors impact counsellor experiences of professional identity and secondary trauma in mental health settings.     

Do We Know Where We Stand? Neighborhood Relative Income,Subjective Social Status,and Health

Bridging research on relative income and subjective social status (SSS), this study examines how neighborhood relative income is related to ones' SSS, and in turn, physical and mental health. Using a survey sample of 1807 U.S. adults, we find that neighborhood median income significantly moderates the relationship between household income and self‐reported physical and mental health. Low‐income individuals living in high‐income neighborhoods (i.e., relative disadvantage) report better physical and mental health than low‐income individuals living in low‐income neighborhoods. In addition, high‐income individuals living in low‐income neighborhoods (i.e., relative advantage) report higher SSS (relative to neighbors), whereas low‐income individuals living in high‐income neighborhoods (i.e., relative disadvantage) also report higher SSS. We draw from social comparison theory to interpret these results positing that downward comparisons may serve an evaluative function while upward comparisons may result in affiliation with better‐off others. Finally, we demonstrate that SSS explains the relationship between neighborhood relative income and health outcomes, providing empirical support for the underlying influence of perceived social position.     

An analysis of reinforcement sensitivity theory and the five-factor model

Reinforcement Sensitivity Theory (RST) and the Five-Factor Model (FFM) are two prominent personality accounts that have emerged from different backgrounds. Although the two accounts are applied to similar research topics, there is limited empirical work examining the correspondence between them. The current study explored the relationship between RST-based personality traits and the FFM domains and facets in an undergraduate sample (n = 668). Regression analyses indicated that Sensitivity to Punishment (SP) was positively associated with Neuroticism and Agreeableness, and negatively associated with Extraversion, Openness, and Conscientiousness. In contrast, Sensitivity to Reward (SR) was positively associated with Extraversion and Neuroticism, and negatively associated with Agreeableness and Conscientiousness. Exploratory analyses at the facet level specified the relationship between SP, SR, and each domain. A factor analysis was also conducted to explore the higher-order factor structure of RST and the FFM domains. Three factors emerged, which we labelled SP, Stability-Impulsivity, and Sensation Seeking. Taken together, these findings suggest that there is substantial overlap between these two accounts of personality. Copyright © 2007 John Wiley & Sons, Ltd.

I Think We’re Alone Now: Solitary Social Behaviors in Adolescents with Autism Spectrum Disorder

Research into emotional responsiveness in Autism Spectrum Disorder (ASD) has yielded mixed findings. Some studies report uniform, flat and emotionless expressions in ASD; others describe highly variable expressions that are as or even more intense than those of typically developing (TD) individuals. Variability in findings is likely due to differences in study design: some studies have examined posed (i.e., not spontaneous expressions) and others have examined spontaneous expressions in social contexts, during which individuals with ASD—by nature of the disorder—are likely to behave differently than their TD peers. To determine whether (and how) spontaneous facial expressions and other emotional responses are different from TD individuals, we video-recorded the spontaneous responses of children and adolescents with and without ASD (between the ages of 10 and 17 years) as they watched emotionally evocative videos in a non-social context. Researchers coded facial expressions for intensity, and noted the presence of laughter and other responsive vocalizations. Adolescents with ASD displayed more intense, frequent and varied spontaneous facial expressions than their TD peers. They also produced significantly more emotional vocalizations, including laughter. Individuals with ASD may display their emotions more frequently and more intensely than TD individuals when they are unencumbered by social pressure. Differences in the interpretation of the social setting and/or understanding of emotional display rules may also contribute to differences in emotional behaviors between groups.     

Mindfulness and Emotional Distress: the Mediating Role of Psychological well-Being

The present cross-sectional study aimed to clarify the relationships among specific facets of dispositional mindfulness, psychological well-being, and emotional distress. To understand the relationships among these variables is crucial in order to expand the knowledge of the processes underlying mindfulness effects and to develop effective interventions. The participants (119 Italian males and females; mean age = 29 years) completed self-report questionnaires assessing mindfulness (i.e., observing, describing, acting with awareness, non-judging of inner experience, non-reactivity to inner experience), emotional distress, and psychological well-being. Path analysis revealed that each facet of mindfulness played a unique role in influencing emotional suffering. In line with our prediction, no significant correlation emerged between the observing facet and either psychological well-being or emotional distress. Both the capacity to describe inner events and to act with awareness had an indirect effect on emotional distress, which was fully mediated by the perception of psychological well-being. On the other hand, the capacity for non-reacting to emotions and thoughts directly influenced emotional distress. Interestingly, non-judging inner events showed both a direct and indirect effect on the outcome variable. These findings confirmed the significant role of psychological well-being in mediating the relationship between some facets of mindfulness and emotional distress. Moreover, different mindfulness abilities play specific roles in reducing emotional distress, so mindfulness should be considered as a multidimensional construct.     

Perceptions of Adequate Personal Time and Wellbeing among African American Families with Adolescents

The current study examines the perception of adequate personal or leisure time, and its association with family and caregiver functioning, among a sample of low-income African American families. The investigation is grounded in Conservation of Resources (COR) theory which predicts that caregivers who perceive more adequate personal time will also report higher levels of optimism and lower levels of depressive symptoms, and will have adolescents who report more household routines and less psychologically controlling parenting. A total of 115 caregiver-adolescent (age 14–18) dyads were recruited from a low-income, predominantly African American neighborhood in a major metropolitan center in the United States as part of a larger survey on African American family life. Results indicate that caregivers report perceiving inadequate amounts of time to sleep, get enough exercise, and relax. Caregivers also report comparatively less adequate personal time than time with children. Analyses reveal that caregivers who perceive having more adequate leisure or personal time, report fewer depressive symptoms and higher levels of optimism, after controlling for perceptions of adequate financial resources. Alternatively, there was no association between perceptions of free or leisure time and parenting behaviors, including maintenance of household routines and the use of psychological control. The results underscore the need to examine non-material resources, and their association with wellbeing.     

Socioeconomic status and hippocampal volume in children and young adults

An individual's socioeconomic status (SES) is often viewed as a proxy for a host of environmental influences. SES disparities have been linked to variance in brain structures particularly the hippocampus, a neural substrate of learning and memory. However, it is unclear whether the association between SES and hippocampal volume is similar in children and adults. We investigated the relationship between hippocampal volume and SES in a group of children (n = 31, age 8–12 years) and a group of young adults (n = 32, age 18–25 years). SES was assessed with four indicators that loaded on a single factor, therefore a composite SES scores was used in the main analyses. Hippocampal volume was measured using manual demarcation on high resolution structural images. SES was associated with hippocampal volume in the children, but not in adults, suggesting that in childhood, but not adulthood, SES‐related environmental factors influence hippocampal volume. In addition, hippocampal volume, but not SES, was associated with scores on a memory task, suggesting that net effects of postnatal environmental factors, captured by SES, are more distal determinants of memory performance than hippocampal volume. Longitudinal investigation of the association between SES, hippocampal volume and cognitive functioning may further our understanding of the putative neural mechanisms underlying SES‐related environmental effects on cognitive development.
