Work,Nonwork, and Sleep (WNS): a Review and Conceptual Framework

The current paper expands on traditional views of the work-nonwork interface to incorporate the critical component of sleep. We integrate past theoretical and empirical work from the sleep and organizational science literatures to inform a novel framework that will facilitate research evaluating associations among work, nonwork, and sleep, the three major areas of life. We propose that attitudes, behaviors, and states emerging in work and nonwork domains cannot be fully understood without taking into account upstream and downstream sleep quantity and quality effects. Rather, periods of sleep bookend engagement in work and nonwork roles. Thus, we propose the work, nonwork, and sleep (WNS) conceptual framework and, in doing so, identify specific, underlying resource mechanisms (i.e., human energy and time) operating both intra-individually and inter-individually. We also discuss contextual factors that act as predictors and moderators of these relationships. We suggest that a unifying framework explaining connections and underlying processes among work, nonwork, and sleep is necessary for applied psychology and management disciplines to significantly contribute to future research, intervention development and dissemination, and ultimately policy change. We provide a number of avenues for future investigation, including relevant special populations and methodological approaches. Although a plethora of work-nonwork theoretical frameworks exist, none have incorporated the third major area of life: sleep. We call for the expansion and acknowledgement of sleep, an important source of variance in everyday attitudes, behaviors, and states, and ultimately in long-term organizational, family, and individual health and well-being.     

<Emphasis Type="Italic">Wh</Emphasis>-Questions,Universal Statements and Free Choice Inferences in Child Mandarin

This study investigated 5-year-old Mandarin-speaking children’s comprehension of wh-questions, universal statements and free choice inferences. Previous research has found that Mandarin-speaking children assign a universal interpretation to sentences with a wh-word (e.g., shei ‘who’) followed by the adverbial quantifier dou ‘all’ (Zhou in Appl Psycholinguist 36:411–435, 2013). Children also compute free choice inferences in sentences that contain a modal verb in addition to a wh-word and dou (Zhou, in: Nakayama, Su, Huang (eds.) Studies in Chinese and Japanese language acquisition: in honour of Stephen Crain. John Benjamins Publishing Company, Amsterdam, pp 223–235, 2017). The present study used a Question-Statement Task to assess children’s interpretation of sentences containing shei + dou, both with and without the modal verb beiyunxu ‘was allowed to’, as well as the contrast between sentences with shei + dou, which are statements for adults, versus ones with dou + shei, which are wh-questions for adults. The 5-year-old Mandarin-speaking child participants exhibited adult-like linguistic knowledge of the semantics and pragmatics of wh-words, the adverbial quantifier dou, and the deontic modal verb beiyunxu.     

Differences in Scope Assignments for Child and Adult Speakers of Mandarin

The present study used a Truth Value Judgment Task to investigate whether changes in sentence structure lead to corresponding changes in the assignment of scope relations by Mandarin-speaking children and adults. In one condition, participants were presented with ordinary negative sentences containing disjunction; this condition was designed to verify the existing claim that disjunction is a positive polarity item for adult speakers of Mandarin, but not for child speakers. In a second condition, participants were presented with negative sentences where the disjunction phrase was preposed from object position; this condition was designed to examine the extent to which changes in sentence structure can result in changes in scope assignments to negated disjunctions. The results indicate that the preposed disjunction phrase undergoes reconstruction for children, whereas reconstruction is blocked for adults. This finding also suggests that Mandarin-speaking children and adults exhibit different scope preferences for negated disjunctions, regardless of where the disjunction phrase appears in the surface syntax.     

The Role of Attachment Styles and Interpersonal Problems in Suicide‐Related Behaviors

The relationships among adult attachment styles, interpersonal problems, and categories of suicide‐related behaviors (i.e., self‐harm, suicide attempts, and their co‐occurrence) were examined in a predominantly psychiatric sample (N = 406). Both anxious and avoidant attachment styles were associated with interpersonal problems. In turn, specific interpersonal problems differentially mediated the relations between attachment style and type of suicide‐related behaviors. These findings suggest the importance of distinguishing between these groups of behaviors in terms of etiological pathways, maintenance processes, and treatment interventions.     

Medroxyprogesterone acetate impairs memory and alters the GABAergic system in aged surgically menopausal rats

In women, medroxyprogesterone acetate (MPA) is the most commonly used progestin component of hormone therapy (HT). In vitro, MPA negatively impacts markers of neuronal health and exacerbates experimentally-induced neurotoxicity. There is in vitro evidence that these factors are driven by GABAergic and neurotrophic systems. Whether these effects translate to a negative impact on brain function has not been tested in vivo, clinically or preclinically. Here we evaluate the mnemonic and neurobiological effects of MPA in the surgically menopausal rat. Aged ovariectomized (OVX) rats were given subcutaneous vehicle, natural progesterone, low-dose MPA or high-dose MPA. Multiple cognitive domains were analyzed via the water radial-arm maze (WRAM) and Morris maze (MM). Cognitive brain regions were assayed for changes in the GABAergic system by evaluating GAD protein, the synthesizing enzyme for GABA, and neurotrophins. On the WRAM, both progestin types impaired learning. Further, high-dose MPA impaired delayed memory retention on the WRAM, and exacerbated overnight forgetting on the MM. While neurotrophins were not affected by progesterone or MPA treatment, both progestin types altered GAD levels. MPA significantly and progesterone marginally decreased GAD levels in the hippocampus, and both MPA and progesterone significantly increased GAD levels in the entorhinal cortex. These findings suggest that MPA, the most commonly used progestin in HT, is detrimental to learning and two types of memory, and modulates the GABAergic system in cognitive brain regions, in aged surgically menopausal rats. These findings, combined with in vitro evidence that MPA is detrimental to neuronal health, indicates that MPA has negative effects for brain health and function.     

Non-declarative sequence learning does not show savings in relearning

Researchers have utilized the savings in relearning paradigm in a variety of settings since Ebbinghaus developed the tool over a century ago. In spite of its widespread use, we do not yet understand what type(s) of memory are measurable by savings. Specifically, can savings measure both declarative and non-declarative memories? The lack of conscious recollection of the encoded material in some studies indicates that non-declarative memories may show savings effects, but as all studies to date have used declarative tasks, we cannot be certain. Here, we administer a non-declarative task and then measure savings in relearning the material declaratively. Our results show that while material outside of awareness may show savings effects, non-declarative sequence memory does not. These data highlight the important distinction between memory without awareness and non-declarative memory.     

The integration of individual and family therapy

It is time to put an end to the separation in training programs between individual and family therapy. Competent therapists should be able to think at an intrapsychic and circular level concurrently. Training programs should maintain their current major focus and develop their minor area of expertise sufficiently so that their graduates can practice both individual and family therapy and choose whichever modality is more appropriate to the case at the time. Bridge concepts, essential differences, and some integrative approaches in individual and marriage and family therapy are discussed.
