Differentiation of Self Predicts Life Satisfaction through Marital Adjustment

Abstract

Previous studies have documented the link between differentiation of self and life satisfaction. However, the underlying mechanisms explaining these associations are yet to be tested at the dyadic level. This study examined the mediating role of marital adjustment in the association between differentiation of self and life satisfaction among 113 Turkish heterosexual married couples (N?=?226). Analyses using the Common Fate Model demonstrated that differentiation of self was associated with higher levels of marital adjustment and life satisfaction, such that marital adjustment was positively associated with life satisfaction, and in turn, marital adjustment fully mediated this association. Implications are discussed for clinicians and cross-cultural researchers who seek to promote greater life satisfaction by targeting both differentiation and marital adjustment.     

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.

     

The missing link between faces and names: Evidence from Alzheimer's disease patients

Retrieval of proper names is a cause of concern and complaint among elderly adults and it is an early symptom of patients suffering from neurodegenerative diseases such as Alzheimer's disease (AD). While it is well established that AD patients have deficits of proper name retrieval, the nature of such impairment is not yet fully understood. Specifically, it is unknown whether this deficit is due to a degradation of the links between faces and proper names, or due to deficits in intentionally accessing and retrieving proper names from faces. Here, we aim to investigate the integrity of the links between famous faces and proper names in AD while minimizing the impact of the explicit retrieval. We compare the performances of AD patients and elderly controls in a face-name priming task. We assess the integrity of the link between faces and names at two different levels: identity level - the name and face belong to the same person; and semantic level - the name and face belong to the same category (e.g., politicians). Our results reveal that AD patients compared with controls show intact semantic priming but reduced priming for person identity. This suggests that the deficits in intentionally retrieving proper names in AD are the result of a partial disruption of the network at the identity level, i.e., the links between known faces and proper names.     

Changing prejudiced attitudes,promoting egalitarianism,and enhancing diversity through fundamental processes of persuasion

ABSTRACT

We review work from persuasion science relevant to reducing prejudiced attitudes. We begin by introducing the idea that the thoughts people generate – their number and valence – are critical for understanding when responding to persuasive attempts will result in egalitarian attitudes. A focus on thinking highlights the importance of understanding short and long-term attitude change in promoting diversity. How much people think is also consequential for spreading of initial change to more distal attitudes and generalization of change to other judgments. The second section describes a process of thought validation that emphasizes the importance of considering what people think and feel about their own thoughts. This meta-cognitive process is shown to make a difference in producing consequential changes in reducing prejudiced attitudes toward African Americans, immigrants, refugees, individuals with disabilities, and beyond. The conditions under which variables such as minority status and stigmatized sources affect elaboration and validation are also specified. The fourth section explores how these two processes are relevant for understanding explicit and implicit ambivalence and change in the domain of prejudiced attitudes. We highlight the utility of a process-oriented approach for designing future research and promoting more inclusive attitudes and actions.     

Reducing Proactive Interference in Motor Tasks

Abstract

Changing automatized movement patterns often leads to initial performance decrements caused by proactive interference. In this study, we scrutinized whether proactive interference could be reduced by inhibiting the to-be-changed movement pattern by means of a physical movement constraint and verbal inhibition instructions, and whether any of the two interventions may be superior. Skilled typists typed short texts as fast and accurately as possible on a regular QWERTZ keyboard. After baseline measures, a new rule prohibiting the use of the left index finger was introduced. Subsequently, participants took part in either a verbal instruction or an additional motor restriction intervention phase. Results revealed that the original rule change was successful in inducing proactive interference in skilled typists. Most importantly, the two interventions similarly reduced proactive interference both immediately following the rule change and after ten practice sessions. We conclude that reducing proactive interference by means of physical motor restrictions and verbal instructions may be equally effective.
