Should we suppress or reappraise our stress?: the moderating role of reappraisal on cortisol reactivity and recovery in healthy adults

Background: People differ in their ability to regulate their physiological stress response. Individual differences in emotion regulation strategies such as suppression and reappraisal may explain this differential response to stress.

Objective: The aim of the current study was to assess whether daily use of suppression and reappraisal as well as their interaction predicted physiological stress reactivity and/or recovery, as assessed by variations in cortisol levels.

Method: Thirty-eight healthy young adults (13 men) completed the Emotion Regulation Questionnaire and were exposed to a psychosocial stressor, throughout which salivary cortisol was measured.

Results: Linear regressions showed main effects of reappraisal and suppression on cortisol reactivity and a main effect of suppression on cortisol recovery, where both strategies were positively associated with stress phases. Moreover, results showed a significant interaction of suppression by reappraisal in predicting both cortisol reactivity and recovery. Simple slope tests revealed that reappraisal moderated the association between suppression and both phases of cortisol responsivity.

Conclusion: Our results suggest that reappraisal represents a protective factor against the deleterious effects of suppression on stress responsivity. This study underlines the importance of investigating emotion regulation strategies as a means to understand individual differences in vulnerability to stress-related psychopathologies such as anxiety and depression.     

Critical processes in serial short-term memory: A developmental study

Two experiments are described which were designed to test the possible involvement of two operations in developmental auditory serial short-term memory (SSTM), namely rehearsal proficiency and item identification. The experiments provided mainly negative support for the notion that these operations are critical in developmental SSTM. As an alternative, the possibility that developmental differences in SSTM might have their origins in the processing of speech sound patterns was discussed.     

Prenatal daily musical exposure is associated with enhanced neural representation of speech fundamental frequency: Evidence from neonatal frequency-following responses

Fetal hearing experiences shape the linguistic and musical preferences of neonates. From the very first moment after birth, newborns prefer their native language, recognize their mother's voice, and show a greater responsiveness to lullabies presented during pregnancy. Yet, the neural underpinnings of this experience inducing plasticity have remained elusive. Here we recorded the frequency-following response (FFR), an auditory evoked potential elicited to periodic complex sounds, to show that prenatal music exposure is associated to enhanced neural encoding of speech stimuli periodicity, which relates to the perceptual experience of pitch. FFRs were recorded in a sample of 60 healthy neonates born at term and aged 12–72 hours. The sample was divided into two groups according to their prenatal musical exposure (29 daily musically exposed; 31 not-daily musically exposed). Prenatal exposure was assessed retrospectively by a questionnaire in which mothers reported how often they sang or listened to music through loudspeakers during the last trimester of pregnancy. The FFR was recorded to either a /da/ or an /oa/ speech-syllable stimulus. Analyses were centered on stimuli sections of identical duration (113 ms) and fundamental frequency (F₀ = 113 Hz). Neural encoding of stimuli periodicity was quantified as the FFR spectral amplitude at the stimulus F₀. Data revealed that newborns exposed daily to music exhibit larger spectral amplitudes at F₀ as compared to not-daily musically-exposed newborns, regardless of the eliciting stimulus. Our results suggest that prenatal music exposure facilitates the tuning to human speech fundamental frequency, which may support early language processing and acquisition.

Research Highlights

• Frequency-following responses to speech were collected from a sample of neonates prenatally exposed to music daily and compared to neonates not-daily exposed to music.
• Neonates who experienced daily prenatal music exposure exhibit enhanced frequency-following responses to the periodicity of speech sounds.
• Prenatal music exposure is associated with a fine-tuned encoding of human speech fundamental frequency, which may facilitate early language processing and acquisition.

     

A translational application of music for preschool cognitive development: RCT evidence for improved executive function,self-regulation,and school readiness

The benefits of active music participation and training for cognitive development have been evidenced in multiple studies, with this link leveraged in music therapy approaches with clinical populations. Although music, rhythm, and movement activities are widely integrated into children's play and early education, few studies have systematically translated music therapy-based approaches to a nonclinical population to support early cognitive development. This study reports the follow-up effects of the Rhythm and Movement for Self Regulation (RAMSR) program delivered by generalist preschool teachers in low socioeconomic communities. This randomized control trial (RCT) involved 213 children across eight preschools in disadvantaged communities in Queensland, Australia. The intervention group received 16–20 sessions of RAMSR over 8 weeks, while the control group undertook usual preschool programs. Primary outcome measures included executive function (child assessment of shifting, working memory, and inhibition) and self-regulation (teacher report), with secondary outcomes of school readiness and visual-motor integration. Data were collected pre- and post-intervention, and again 6 months later once children had transitioned into school. Results demonstrated significant intervention effects across the three time points for school readiness (p = 0.038, η_p² = 0.09), self-regulation (p < 0.001, η_p² = 0.08), and inhibition (p = 0.002 η_p² = 0.23). Additionally, the feasibility of building capacity in teachers without any music background to successfully deliver the program was evidenced. These findings are important given that children from low socioeconomic backgrounds are more likely to need support for cognitive development yet have inequitable access to quality music and movement programs.

Research Highlights

• Initial effects of self-regulation from a rhythm and movement program were sustained following transition into school for children from disadvantaged backgrounds.
• Delayed effects of inhibition and school readiness from a rhythm and movement program appeared 6 months post-intervention as children entered school.
• Generalist teachers can successfully implement a rhythm and movement program, which boosts critical developmental cognitive skills.

     

Theory-Based Health Behavior Change: Developing, Testing, and Applying Theories for Evidence-Based Interventions

Theories are needed to explain and predict health behavior, as well as for the design and evaluation of interventions. Although there has been a history of developing, testing, applying, and refining health behavior theories, debates and limitations in evidence exist: The component of theories which, for example, predicts change should be better elaborated so that we can more easily understand what actually drives behavior change. Theories need to be empirically testable in two ways. Theories need to specify a set of changeable predictors to describe, explain, and predict behavior change, and they should enable us to design an effective intervention that produces exactly those changes in behavior that are predicted by the relevant theory. To make this possible, theories need to be specified in such a way that they can be rigorously tested and falsified. Moreover, for the design of theory-based interventions it must be possible to derive change techniques from the theory and to use them to generate changes in behavior. Based on eight state-of-the-science articles that make conceptual and empirical contributions to the current debate on health behavior theories, various approaches are discussed to gain further insights into explaining and changing health behaviors and the iterative process of theory development.     

Values at Work: The Impact of Personal Values in Organisations

This paper reviews and integrates past research on personal values in work organisations, seeking to portray the role personal values play in shaping the choices and behaviour of individuals in work settings. We start by addressing the role of values in the occupational choice people make. We then review research on the relationships of personal values to a variety of behaviours at work. We continue with discussing the multiple paths through which managers’ values affect organisations and their members. In the last section, we address the interplay between organisational levels, and discuss the congruency between personal and organisational values and its implications for organisations and their employees. Together, the research reviewed indicates how the broadness and stability of values make them an important predictor of behaviour at various levels of the organisation. We end by discussing directions for future research on values in organisations.
