The mediating role of locus of control between social resource stability and psychological well-being

Past research has shown that social resources and locus of control are strongly linked to well-being, but most research has focused on the amount rather than the stability of those resources. The goal of this study was to investigate the mediating role that locus of control had on the relationship between social resource stability and psychological well-being. All three studies measured social resources and well-being through online surveys (Studies 1 and 2 through SONA, and Study 3 through Mechanical Turk). Study 1 (n = 298 college students) demonstrated that social resource stability predicted lower psychological distress, while controlling for social resource amount. Study 2 (n = 300 college students) revealed that social resource stability predicted higher subjective well-being, while controlling for social resource amount, and that locus of control mediated the association. Study 3 (n = 346 working adults) replicated the findings of Studies 1 and 2 using a nonacademic sample and alternative measures of well-being.     

A measurement model of women's behavioral risk taking.

The current study was designed to gain a better understanding of the nature of the relationship between substance use and sexual risk taking within a community sample of women (N = 1,004). Using confirmatory factor analysis, the authors examined the factor structure of sexual risk behaviors and substance use to determine whether they are best conceptualized as domains underlying a single, higher order, risk-taking propensity. A 2 higher order factor model (sexual risk behavior and substance use) provided the best fit to the data, suggesting that these 2 general risk domains are correlated but independent factors. Sensation seeking had large general direct effects on the 2 risk domains and large indirect effects on the 4 first-order factors and the individual indicators. Negative affect had smaller, yet still significant, effects. Impulsivity and anxiety were unrelated to sexual health risk domains.     

Observing responses in rats: Support for the secondary reinforcement hypothesis

Rats' lever presses on a retractable lever earned brief presentations of discriminative stimuli signalling periods in which responding on an alternative lever was either non-reinforced (extinction) or reinforced on a random ratio schedule. The predictions of two theoretical accounts of this behaviour were tested by studying the effects of omitting either the stimulus signalling the reinforced or that signalling the non-reinforced schedule component. Under these conditions rats' behaviour is determined by the conditioned, affective properties of the stimuli rather than by their purely informational properties.     

Persistent alterations in biological profiles in women with abuse histories: influence of premenstrual dysphoric disorder.

OBJECTIVE: To examine dysregulation in biological measures associated with histories of abuse in women and whether women with premenstrual dysphoric disorder (PMDD) differ in their dysregulation. DESIGN: Twenty-five women meeting prospective criteria for PMDD and 42 non-PMDD controls underwent structured interview to determine abuse histories and lifetime Axis I diagnoses, excluding those with current Axis I disorders or using medications. MAJOR OUTCOME MEASURES: Plasma cortisol and norepinephrine (NE), heart rate (HR), blood pressure (BP), and vascular resistance index (VRI) were assessed at rest and in response to mental stress. RESULTS: A greater proportion of PMDD women had prior abuse compared with non-PMDD women. Regardless of PMDD status, all abused women had lower plasma NE and higher HRs and tended to have lower plasma cortisol at rest and during stress. Abused women also reported more severe daily emotional and physical symptoms. Greater VRI and BP at rest and during stress were seen only in PMDD women with abuse. CONCLUSION: There is persistent dysregulation in stress-responsive systems in all abused women that cannot be accounted for by current psychiatric illness or medications, and PMDD women may be differentially more vulnerable to the impact of abuse on measures reflecting alpha-adrenergic receptor function.     

Reaching Up,Down, In,and Around: Couple and Family Coping During the Coronavirus Pandemic

The worldwide coronavirus (COVID-19) has had profound effects on all aspects of life: physical health, the ability to travel locally or to more distant destinations, material and financial resources, and psychosocial wellbeing. Couples, families, and communities and individual persons in those relationships have struggled to cope with emerging depression, anxiety, and trauma, and the rise of relational conflict. In this article, we suggest that the existential nature of the pandemic’s challenges requires more than just the usual psychosocial interventions. We propose a taxonomy of responses to foster coping and resilience—“Reaching Up, Down, In, and Around.” “Reaching Up” includes accessing spiritual, religious, and ethical values. “Reaching Down” includes ideas and practices that foster a revised relationship with the Earth and its resources, and that engage families to participate in activities that aid the Earth’s recovery from decades of human-caused damage. “Reaching In” represents a turn towards experiences available in the mind and in shared minds in relationships that provide pleasure, excitement, joy, and peace, given that external sources of these emotions are of limited availability due to quarantine. “Reaching Around” involves reframing the mandate for “social distancing” as fostering social connection and support while maintaining physical distancing. The challenges for family therapists, whose practices are confined largely to online therapy, and who are struggling with the same fears and constraints as those persons they are attempting to help, are also discussed.     

Binocular cues in the perception of distance of a point source of light

The ability to make egocentric distance estimates of a single point source of light, seen in darkness and without the cues of changing size and luminance, was investigated in sixteen observers. The attenuation required to maintain constant luminance, when the target was viewed from different distances, was shown to follow the inverse square law providing the angle subtended by the light was less than 20 s arc. Distance changes were also simulated by means of a split mirror which produced vergence cues, or by test lenses to provide accommodation cues. Over the range 0.5 to 9.2 m distance estimates were surprisingly accurate, although there was some overestimation of near and underestimation of far distances. Most observers made good judgements when only convergence cues were varied, whereas no observers made consistently good judgements when only accommodation cues were varied. The difficulties are discussed in terms of the accommodation-convergence link. When distance was simulated by changing convergence and accommodation cues, estimates were not as good as when real distance was changed. Since good estimates were made with brief target exposures, these judgements were not based on subsequent convergence or accommodation changes. It is suggested that the metric or reference against which the apparently absolute judgements were made was the efferent demand signal associated with a 'resting' position of convergence in darkness.     

SPEECH CONVERGENCE AND SPEECH EVALUATION IN FACT-FINDING INTERVIEWS

The purpose of this study was to examine speech convergence and speech evaluation in fact-finding interviews conducted in the field. Forty interviewers (ERs), undergraduates enrolled in a class on interviewing processes, conducted 20–30 minute interviews with selected interviewees (EEs), business persons and professionals in fields of interest to the ERs. Speech behaviors examined included response latency, speech rate, and turn duration; these were coded per one minute intervals of each interaction. Time series regression procedures indicated that both ERs and EEs converged speech rate and response latency toward their interlocutors' performances of these behaviors. Although turn duration convergence did not characterize the entire data set, male-male dyads did converge significantly and male (ER)-female (EE) dyads significantly diverged turn duration. Regarding speech evaluation, there was some evidence that greater response latency similarity, greater speech rate and response latency convergence, and faster ER speech and slower EE speech were positively related to the competence and social attractiveness judgments of participants. Limitations and implications are discussed.
