To go or not to go? Pupillometry elucidates inhibitory mechanisms in motor imagery

Motor imagery (MI) involves consciously performing an action in our minds without engaging in overt physical movement. Although inhibition is crucial to MI, few studies have explored the nature of inhibitory mechanisms underlying this construct. Therefore, little progress has been made in elucidating how or when inhibition is implemented during MI. The present study addressed this unresolved issue by measuring participants’ pupil dilation (an index of attentional effort) as they performed an inhibitory-control (Go/NoGo) procedure in a modified task-switching paradigm. The results showed that inhibitory mechanisms in MI may be implemented via various routes. When MI was the only movement mode used, minimal attentional effort was invested during the Go/NoGo responses, suggesting an early implemented, proactive inhibitory strategy. Conversely, when imagery was preceded by physical movement responses, inhibition required greater attentional effort and it appears as though more active and attention-demanding inhibitory processes must be employed.     

The paradox of decrease and dependent parts

This paper is concerned with the paradox of decrease. Its aim is to defend the answer to this puzzle that was propounded by its originator, namely, the Stoic philosopher Chrysippus. The main trouble with this answer to the paradox is that it has the seemingly problematic implication that a material thing could perish due merely to extrinsic change. (For, intuitively, it is not possible for a mere extrinsic change to cause a material thing to cease to be.) It follows that in order to defend Chrysippus’ answer to the paradox, one has to explain how it could be that Theon is destroyed by the amputation without changing intrinsically. In this paper, I shall answer this challenge by appealing to the broadly Aristotelian idea that at least some of the proper parts of a material substance are ontologically dependent on that substance. I will also appeal to this idea in order to offer a new solution to the structurally similar paradox of increase. In this way, we will end up with a unified solution to two structurally similar paradoxes.     

Reassuring sex: Can sexual desire and intimacy reduce relationship‐specific attachment insecurities?

Past research has shown that attachment orientations shape sexual processes within relationships. Yet, little has been done to explore the opposite direction. In the present research, we examined whether sexual desire and emotional intimacy reduce attachment insecurities over time in emerging relationships. In an 8‐month longitudinal study, we followed 62 newly dating couples across three measurement waves. At Time 1, romantic partners discussed sexual aspects of their relationship and judges coded their displays of sexual desire and intimacy. Participants also completed measures of relationship‐specific attachment anxiety and avoidance in each wave. The results indicated that men's displays of desire predicted a decline in their own and their partner's relationship‐specific insecurities. Conversely, women's displays of desire inhibited the decline in their partner's relationship‐specific insecurities, whereas women's displays of intimacy predicted a decline in their partner's relationship‐specific insecurities. These findings suggest that different sex‐related processes underlie attachment formation in men and women.     

The spirituality of People of Color living with AIDS in long-term care

This article describes research results regarding the role of religion/spirituality among the chronically ill that highlights the benefits of religious beliefs and practices on patient health and well being. The author reports results from a questionnaire administered to People of Color living with AIDS who reside in a nursing home. The results suggest a strong spirituality as evidenced in a desire to communicate with God through frequent prayer and the reading of the patient's Holy Book. It includes high levels of hope, feelings of being loved, and attendance at religious services and classes held in the nursing home.     

Yoga-integrated psychotherapy for emotion dysregulation: A pilot study

Aims & Objectives

Yoga has been evidenced as beneficial for physical and mental health. This study sought to pilot the acceptability and feasibility of a yoga-integrated psychotherapy (YiP) intervention, aimed at alleviating difficulties in emotion regulation. A further aim was to explore the perceived effectiveness of YiP in alleviating depression, anxiety and improving well-being.

Methods

Seven participants who scored significantly on the Difficulties in Emotion Dysregulation Scale (DERS) took part in a psychological assessment session followed by six weekly one hr therapy sessions. Participants completed self-report measures in each session to quantify the effects of each YiP session on emotion regulation, well-being, depression and anxiety. Following seven sessions, five participants completed qualitative follow-up interviews to explore subjective experiences of YiP and any perceived impacts.

Findings

An ANOVA that contained data from seven participants who completed all six sessions revealed that DERS scores were significantly lower, and well-being scores were significantly higher, at both mid and end-points than at baseline. Thematic analysis of qualitative interviews identified five themes: “YiP assists the client's psychological and emotional processing,” “YiP improves insight and focus,” “YiP is culturally sensitive,” “the body facilitates regulation and resilience” and “YiP is acceptable & impactful.”

Conclusion

The study presents promising findings for the integration of yoga into psychotherapeutic practice and indicates that YiP may have beneficial effects on emotion regulation and psychological well-being. Future research should use randomised controlled methodologies to examine the ability of YiP to alleviate a wide range of affective symptoms using a larger sample of participants.     

AIDS and condom-related knowledge,beliefs, and behaviors in Mexican migrant laborers

A survey of 87 Mexican migrants (55 males and 32 females) who have lived and worked in the US since 1982 assessed AIDS and condom-related knowledge, beliefs, and sexual practices. Although respondents were highly knowledgeable about major modes of HIV transmission, one-third to one-half believed that HIV could be contracted from mosquito bites, public bathrooms, kissing, and the HIV test. Only 15% knew someone with AIDS. Ever-use of condoms was reported by 70.9% of men and 41.9% of women. Of the 68 subjects who had been sexually active in the year preceding the survey, 20 reported two or more partners. Among sexually active respondents, 16.2% always used condoms with their primary partner, while 43.0% used condoms consistently with occasional partners. 48.9% of men and 57.1% of women never used condoms with their primary partner; with casual partners, these rates were 30.8% and 44.4%, respectively. Worry about contracting AIDS, self-rated on a scale from 1 (very often) to 4 (never), averaged 2.84, with higher worry scores among those 18-31 years of age and with multiple partners. Respondents did not anticipate negative consequences of condom use (e.g., reduced sexual pleasure), but females expressed concern that carrying condoms would cause them to be viewed as promiscuous.
