Leisure activities, caregiving demands and catecholamine levels in dementia caregivers

This study examined whether satisfaction from leisure activities moderates the relationship between caregiving demands (i.e., hours per day spent caring for a spouse with dementia) and resting levels of the catecholamines norepinephrine (NE) and epinephrine (EPI). Spousal caregivers (n?=?107; mean age?=?73.95?±?8.12 years) were assessed in home for plasma levels of NE and EPI, amount of care provided, and leisure satisfaction. Regression was used to determine whether leisure satisfaction moderated the relationship between hours providing care per day and catecholamine levels. A significant interaction was found between hours caregiving and leisure satisfaction for NE, but not for EPI. Post?hoc regressions were conducted for both NE and EPI. At low leisure satisfaction, time spent caring for a spouse was positively associated with plasma NE (β?=?0.41; p?=?0.005) and EPI (β?=?0.44; p?=?0.003). In contrast, at high levels of satisfaction, time caregiving was not significantly associated with plasma NE (β?=?-0.08; p?=?0.57) or EPI (β?=?0.23; p?=?0.12). These findings suggest that leisure satisfaction may protect caregivers from increases in catecholamines, which have been implicated in cardiovascular risk. Further support for these findings may impact psychological treatments for distressed caregivers.     

Understanding childcare satisfaction and its effect on workplace outcomes: The convenience factor and the mediating role of work‐family conflict

Building on Hobfoll's (1989, 2001) conservation of resources theory, we posit childcare is an essential resource to working parents. In addition to previously demonstrated childcare satisfaction (CCS) dimensions, we propose and demonstrate empirical support for a convenience dimension of CCS. Satisfaction with caregiver convenience refers to a parent's evaluation of the caregiver's location and availability. We hypothesize that time‐related dimensions of CCS (caregiver dependability and convenience) relate to employee well‐being and withdrawal, because they diminish time‐based family interfering with work (FIW). We also propose quality‐related CCS dimensions (caregiver attentiveness, communication, and cost) relate to psychological well‐being, because they reduce strain‐based FIW. Survey data from a sample of 316 university employees (faculty and staff) who were parents of under school‐age children (infancy through preschool) revealed time‐based FIW as an explanatory mechanism for the relationships between satisfaction with caregiver convenience and both turnover intentions and absenteeism (due to childcare issues). In addition, strain‐based FIW mediated the effects of satisfaction with caregiver attentiveness on well‐being and satisfaction with caregiver cost on well‐being. This study expands previous research on CCS by demonstrating that CCS is related to important work outcomes in part because it reduces time‐ and strain‐based FIW.     

Assessment of executive functioning in childhood epilepsy: The Tower of London and BRIEF

Children and adolescents with epilepsy are known to demonstrate executive function dysfunction, including working memory deficits and planning deficits. Accordingly, assessing specific executive function skills is important when evaluating these individuals. The present investigation examined the utility of two measures of executive functions—the Tower of London and the Behavioral Rating Inventory of Executive Functioning (BRIEF)—in a pediatric epilepsy sample. Ninety clinically referred children and adolescents with seizures were included. Both the Tower of London and BRIEF identified executive dysfunction in these individuals, but only the Tower of London variables showed significant relations with epilepsy severity variables such as age of epilepsy onset, seizure frequency, number of antiepileptic medications, etc. Further, the Tower of London and BRIEF variables were uncorrelated. Results indicate that objective measures of executive function deficits are more closely related to epilepsy severity but may not predict observable deficits, as reported by parents. Comprehensive evaluation of such deficits, therefore, should include both objective measures as well as subjective ratings from caregivers.     

Assessing the Effectiveness of a Trauma-Oriented Approach to Treating Prostituted Women in a Prison and a Community Exiting Program

Women who have been prostitutes are social work clients in many clinical, correctional, and community settings. Unique programming that addresses the high levels of trauma symptoms reported by prostituted women has yet to be explored. The purpose of this study is to explore the effectiveness of a group trauma and abuse intervention for prostituted women from two settings, prison and a community exiting program. A quasi-experimental research design was used. Twenty-nine women participated in a 12-week psychoeducational trauma and abuse intervention program called Esuba. All participants reported decreases in trauma symptoms, but the prison group showed a greater number of significant changes in trauma symptomology than the community group. Implications for practice and future research implications are discussed.     

Conscious thoughts from reflex-like processes: A new experimental paradigm for consciousness research

The contents of our conscious mind can seem unpredictable, whimsical, and free from external control. When instructed to attend to a stimulus in a work setting, for example, one might find oneself thinking about household chores. Conscious content thus appears different in nature from reflex action. Under the appropriate conditions, reflexes occur predictably, reliably, and via external control. Despite these intuitions, theorists have proposed that, under certain conditions, conscious content resembles reflexes and arises reliably via external control. We introduce the Reflexive Imagery Task, a paradigm in which, as a function of external control, conscious content is triggered reliably and unintentionally: When instructed to not subvocalize the name of a stimulus object, participants reliably failed to suppress the set-related imagery. This stimulus-elicited content is considered ‘high-level’ content and, in terms of stages of processing, occurs late in the processing stream. We discuss the implications of this paradigm for consciousness research.     

Chickadees fail standardized operant tests for octave equivalence

Octave equivalence occurs when an observer judges notes separated by a doubling in frequency perceptually similar. The octave appears to form the basis of pitch change in all human cultures and thus may be of biological origin. Previously, we developed a nonverbal operant conditioning test of octave generalization and transfer in humans. The results of this testing showed that humans with and without musical training perceive the octave relationship between pitches. Our goal in the current study was to determine whether black-capped chickadees, a North American songbird, perceive octave equivalence. We chose these chickadees because of their reliance on pitch in assessing conspecific vocalizations, our strong background knowledge on their pitch height perception (log-linear perception of frequency), and the phylogenetic disparity between them and humans. Compared to humans, songbirds are highly skilled at using pitch height perception to classify pitches into ranges, independent of the octave. Our results suggest that chickadees used that skill, rather than octave equivalence, to transfer the note-range discrimination from one octave to the next. In contrast, there is evidence that at least some mammals, including humans, do perceive octave equivalence.     

Reply to the Comments of Longuenesse and Ginsborg

In this discussion I respond to some of the criticisms raised by Béatrice Longuenesse and Hannah Ginsborg to my account of Kant's aesthetic theory presents in Kant's Theory of Taste.     

Different perspectives on measuring lifestyle engagement: a comparison of activity measures and their relation with cognitive performance in older adults

Given the limitations associated with assessing activity engagement via the frequency of specific activities, it may be valuable to consider the characteristics of an activity. The method of asking individuals to report the amount of time spent engaging in activities that have certain characteristics was compared to a specific activity questionnaire, and a daily diary regarding their relation to cognitive functioning. Participants 60–90 years old (n = 187) completed the activity measurement methods and a series of cognitive tasks. Structural equation models showed that all three activity methods were predictive of adults’ cognitive performance, but no measure predicted all outcomes. Each activity measure provided unique information. Notably, the combination of the measurement types predicted more variance than any of the measures alone. There is additional power to predict cognition when multiple activity measurement methods are used, and daily assessment can be a valuable tool to augment traditional specific activity questionnaires.
