Temporal pattern and spectral complexity as stimulus parameters for eliciting a cardiacorienting reflex inhuman fetuses

The purpose of this study was to determine whether temporal pattern and/or spectral complexity were important stimulus parameters for eliciting a cardiac orienting reflex (OR) in low-risk human fetuses. Each of 28 term fetuses was exposed to four sounds formed from the four different combinations of temporal pattern (pulsed, continuous) and spectral complexity (sine wave, IsJ). The fetal cardiac electrical signal was captured transabdominally at a rate of 1024 Hz, and fetal R-waves were extracted by using adaptive signal-processing techniques. We found that pulsed sounds elicited a significantly greater decrease in heart rate (HR) than did continuous sounds. However, the HR response was relatively unaffected by spectral complexity. For the pure tone and the phoneme used in this study, our results indicate that temporal characteristics were more effective at eliciting a cardiac OR in human fetuses than was spectral complexity.     

Counselor Empathy; Religiosity; and Lesbian,Gay, and Bisexual Perspectives

Values-based conflicts, such as between counselor religiosity and ability to work with lesbian, gay, and bisexual (LGB) clients, can present a challenge for counselors and trainees who seek to provide ethical and competent care. Because empathy can facilitate understanding a client's frame of reference, the authors examined the relationships between counselor religiosity, empathy, and LGB perspectives, as well as the potential mediating effects of empathy on values conflicts. The authors discuss implications for counselor education and practice.

Excitatory and inhibitory learning with absent stimuli

Three experiments showed that 2 associatively activated stimulus representations may engage in excitatory or inhibitory learning, depending on their temporal relationship. Experiment 1a suggested that simultaneously activated stimulus representations show evidence of inhibitory learning in an acquisition test. Experiment 1b showed similar evidence of inhibition in a summation test. Experiment 2 found that activation of 2 stimulus representations in a serial compound resulted in excitatory learning between the antecedent and the subsequent (forward) and inhibitory learning between the subsequent and the antecedent (backward). The results show the dynamic influence of temporal contiguity on mediated learning.     

Adult romantic relationships as contexts of human development: a multimethod comparison of same-sex couples with opposite-sex dating, engaged, and married dyads

This article presents a multimethod, multi-informant comparison of community samples of committed gay male (n=30) and lesbian (n=30) couples with both committed (n=50 young engaged and n=40 older married) and noncommitted (n=109 exclusively dating) heterosexual pairs. Specifically, in this study the quality of same- and opposite-sex relationships was examined at multiple levels of analysis via self-reports and partner reports, laboratory observations, and measures of physiological reactivity during dyadic interactions. Additionally, individuals in same-sex, engaged, and marital relationships were compared with one another on adult attachment security as assessed through the coherence of participants' narratives about their childhood experiences. Results indicated that individuals in committed same-sex relationships were generally not distinguishable from their committed heterosexual counterparts, with one exception--lesbians were especially effective at working together harmoniously in laboratory observations.     

Mindful social inferences: Decentering decreases hostile attributions

While research indicates that mindfulness can benefit individual well-being, less is known about its potential impact in the interpersonal domain. In the current research, we examined whether a central element of mindfulness—decentering—decreases hostile attributions in ambiguous social situations. We hypothesized that decentering from experiences—observing and considering them as mental events that arise and disappear—hampers the development of hostile attributions. A series of three laboratory studies, two of which were high-powered and pre-registered, demonstrated that decentering decreases hostile attribution in response to ambiguous social scenarios as compared to immersion instructions, and as compared to baseline. Additionally, the results suggest that decentering may be particularly beneficial in reducing hostile attribution bias among participants high in trait rumination. The current findings provide initial insights into the effect of decentering on the development of hostile attribution bias, and the association between mindfulness and interpersonal responses more generally.
