Sleep disruption explains age-related prospective memory deficits: implications for cognitive aging and intervention

The high prevalence of sleep disruption among older adults may have implications for cognitive aging, particularly for higher-order aspects of cognition. One domain where sleep disruption may contribute to age-related deficits is prospective memory—the ability to remember to perform deferred actions at the appropriate time in the future. Community-dwelling older adults (55–93 years, N = 133) undertook assessment of sleep using actigraphy and participated in a laboratory-based prospective memory task. After controlling for education, sleep disruption (longer awakenings) was associated with poorer prospective memory. Additionally, longer awakenings mediated the relationship between older age and poorer prospective memory. Other metrics of sleep disruption, including sleep efficiency and wake after sleep onset, were not related to prospective memory, suggesting that examining the features of individual wake episodes rather than total wake time may help clarify relationships between sleep and cognition. The mediating role of awakening length was partially a function of greater depression and poorer executive function (shifting) but not retrospective memory. This study is among the first to examine the association between objectively measured sleep and prospective memory in older adults. Furthermore, this study is novel in suggesting sleep disruption might contribute to age-related prospective memory deficits; perhaps, with implications for cognitive aging more broadly. Our results suggest that there may be opportunities to prevent prospective memory decline by treating sleep problems.     

Teachers’ reflections of instructional effectiveness: self-assessment through a standards-based appraisal process

This paper explores teachers’ reflections on: (1) self-assessment of their own videotaped lesson using a standards-based appraisal system; (2) comparison to an external reviewer’s evaluation of the same lesson; and (3) effect of the appraisal system on their pedagogical views, professional development, and actual practice improvement. Findings indicate that teachers view the appraisal system as evaluative with little impact on their teaching practice and professional growth. Participating teachers indicated that the self-evaluative reflection process utilized in the study had a greater influence on their professional development than the appraisal system as it is currently structured.     

How do location and control over the music influence listeners’ responses?

This study uses Mehrabian and Russell's ( 1974 ) Pleasure‐Arousal‐Dominance (PAD) model to consider how responses to both the music heard and overall in‐situ listening experience are influenced by the listener's degree of control over music selected for a particular listening episode and the location in which the listening takes place. Following recruitment via campus advertisements and a university research participation program, 216 individuals completed a background questionnaire and music listening task in a 3 (location) × 2 (experimenter‐ or participant‐selected music) design. After the listening task, participants completed a short questionnaire concerning the music they heard and the overall in‐situ listening experience. Results demonstrated that there was a positive relationship between control and liking for the music and episode, whether the former was considered in terms of: (1) whether the music was self‐selected or experimenter‐selected or (2) overt ratings of perceived control. Furthermore, the location and liking for the music were related to people's judgments of their enjoyment of the overall experience. This research indicates that the PAD model is a useful framework for understanding everyday music listening and supports the contention that, in a musical context, dominance may be operationalized as control over the music.     

Do actions speak louder than words? Examining children’s ability to follow instructions

The ability to encode, retain, and implement instructions within working memory is central to many behaviours, including classroom activities which underpin learning. The three experiments presented here explored how action—planned, enacted, and observed—impacted 6- to 10-year-old’s ability to follow instructions. Experiment 1 (N = 81) found enacted recall was superior to verbal recall, but self-enactment at encoding had a negative effect on enacted recall and verbal recall. In contrast, observation of other-enactment (demonstration) at encoding facilitated both types of recall (Experiment 2a: N = 81). Further, reducing task demands through a reduced set of possible actions (Experiment 2b; N = 64) led to a positive effect of self-enactment at encoding for later recall (both verbal and enacted). Expecting to enact at recall may lead to the creation of an imaginal spatial-motoric plan at encoding that boosts later recall. However, children’s ability to use the additional spatial-motoric codes generated via self-enactment at encoding depends on the demands the task places on central executive resources. Demonstration at encoding appears to reduce executive demands and enable use of these additional forms of coding.     

Knowing without knowing: implicit cognition and the minds of infants and animals / Saber sin saber: la cognición implícita y las mentes de niños pequeños y animales

The main aim of this paper is to highlight the need to address the conceptual problem of ‘implicit knowledge’ or ‘implicit cognition’ — a notion especially important in the study of the nonverbal minds of animals and infants. We review some uses of the term ‘implicit’ in psychology and allied disciplines, and conclude that conceptual clarification of this notion is not only lacking, but largely avoided and reduced to a methodological problem. We propose that this elusive notion is central in the study not only of animal and infant minds, but also the human adult mind. Some promising approaches in developmental and evolutionary psychology towards innovative conceptualization of implicit knowledge remain conceptually underdeveloped and in need of reconsideration and re-elaboration. We conclude by suggesting that the challenge of implicit cognition and nonverbal minds will only be solved through a concerted interdisciplinary approach between psychology and other disciplines.     

Use of social networking sites and associations with skin tone dissatisfaction,sun exposure,and sun protection in a sample of Australian adolescents

Objective: Previous research has indicated that greater exposure to traditional media (i.e. television, film, and print) predicted skin cancer risk factors in adolescents; however, the relationship between social media usage and these outcomes remains unexplored. We examined whether social networking site (SNS) usage, and the particular manner of this use, was associated with skin tone dissatisfaction, sun exposure and sun protection among Australian adolescents. We also explored sex differences in SNS usage related to tanning.

Method: A total of 1856 South Australian secondary school students completed the Australian School Students Alcohol and Drug 2014 survey. SNS usage related to tanning comprised posting pictures, posting text, viewing pictures, viewing text and liking or sharing posts.

Results: Adolescents spent 214.56 minutes, on average, per day using SNSs. Behaviours related to tanning that involved pictures (i.e. viewing pictures, posting pictures, and liking or sharing content) were significantly associated with more skin tone dissatisfaction, more sun exposure and less sun protection. Females performed all SNS-linked behaviours more frequently than did males, with the exception of posting text.

Conclusion: Australian adolescents spend a considerable amount of time using SNSs, and their behaviours related to tanning on these SNSs are significantly associated with skin cancer risk factors.     

Clients’ perceptions of personal psychotherapy or counselling for therapists

The purpose of this study was to examine clients’ opinions of therapists’ personal use of psychotherapy or counselling. Participants in this study, a nationwide sample of clients recruited through Amazon’s MTurk system, were asked to complete an online survey assessing their attitudes towards treatment use by therapists as well as their general attitudes towards psychological help-seeking and perceptions of stigma (social and self) with psychological treatments. In this study, we found that clients generally had positive views about therapists’ personal use of psychotherapy or counselling. Although overall positive attitudes were found, the results from repeated measures ANOVAs indicated that attitudes depended somewhat on whether the therapist had sought out treatment as part of a training requirement for self-enrichment, or for the treatment of a psychological problem. In addition, participating clients were less supportive of therapists disclosing a treatment use history with their clients. Regression analyses also indicated that attitudes towards treatment use by therapists were significantly predicted by general help-seeking attitudes and perceptions of stigma (social and self), but attitudes towards disclosure were not. The findings from this study have important implications regarding therapist treatment use and disclosure in practice.     

The Dynamics of a Genetic Counseling Peer Supervision Group

Supervision is a practice that is utilized by a variety of practitioners to hone their counseling skills. Genetic counselors have embraced the supervision process, and some seek out supervision in a group setting with peers. Researchers have described the structure and content of genetic counseling peer supervision groups, and provided evidence for the benefits of seeking peer supervision. This study aimed to describe the interpersonal aspects of one genetic counseling peer supervision group, including personality traits and group dynamics, and how those factors influenced our experiences within the group. We also describe how the process of evaluating these factors impacted us individually and collectively. There was consensus that the group was a safe and trusting one, which was united by similar goals and mutual respect. Members reported gaining insights about how their own personality functioned within the group milieu, and also how the group setting impacted them. Based on our experiences, we recommend that other peer supervision groups consider similar self-evaluations on a periodic basis, both to enhance group functioning and to allow for increased self-awareness and professional growth.
