Spatial and feature-based memory representation in free-flying homing pigeons

The memory-based recognition of a goal is a capacity well demonstrated in birds, and understanding this ability often involves determining the relative importance of spatial and feature information in representing the properties of a goal. However, surprisingly little avian research has examined goal recognition in a field setting. Here, we demonstrate that homing pigeons can be successfully trained outdoors to fly to and land on a goal platform located in an array of other platforms at a distance on the order of 100 m. They can do so under conditions when the properties of the goal are stable in time as well as when the properties of the goal periodically change; the latter condition indicating that homing pigeons can rapidly adapt their memory representations to take into account changing environmental conditions. When probed for preferential use of either spatial (location) or feature-based (color) information, the pigeons demonstrated an indifferent capacity to use both independent of task demands. The homing pigeon memory systems that support goal recognition appear to be opportunistic with respect to the information exploited, using spatial and feature information equally to guide their behavior. Therefore, and despite strong natural and artificial selection for navigational ability, spatial information is no more important than feature cues in representing a goal location for homing pigeons flying outdoors.     

The Good Behavior Game in preschool classrooms: An evaluation of feedback

The Good Behavior Game (GBG) is a popular group contingency implemented to decrease disruptive behavior in classrooms. However, despite numerous replications of the GBG, there are few direct comparisons evaluating the effectiveness of specific components of the GBG. In the present study, we directly compared the type of feedback delivered during the GBG on the effectiveness of the GBG to reduce disruptive behavior in two preschool classrooms. Results showed that delivering vocal feedback (e.g., “raise your hand”) alone or in combination with visual feedback (i.e., hatch marks) was superior to no feedback or visual feedback alone during the GBG. These results suggest that different variations of the GBG are not equally effective and that a collection of effective procedural variations from which teachers can choose would be beneficial.     

Spousal understanding and marital satisfaction in pain patients and their spouses

The current study tested the hypotheses that knee osteoarthritis (OA) patients and spouses who report more spousal understanding of patient's pain would report greater marital satisfaction. A total of 124 couples completed interviews at three time points across 18 months. Results from dyadic analyses showed that patients who felt more understood by their spouse report, and have spouses who report, higher marital satisfaction concurrently. In addition, patients who felt more understood by their spouse reported higher marital satisfaction over time. Spouses' reports of understanding also had a significant influence on the patients' and their own marital satisfaction concurrently. Results highlight the importance of spouses understanding knee OA patients' pain for both dyad members' marital satisfaction.     

Bridging the Gap Between Hospital and Community-Based Mental Health Services

Depression and anxiety affect a person’s ability to move from hospital to community and engage in valued occupations. The purpose of this study was to understand the effectiveness of an occupational therapist-led transitional service for people with mood and anxiety disorders. Using a mixed-method design consisting of retrospective pre-post analysis of outcome measures and qualitative analysis of interviews with key stakeholders, statistically and clinically significant improvements were seen in depression and anxiety symptoms as well as occupational engagement after completion of the service. This study highlights the unique contributions of occupational therapist-led programing in mental health recovery.     

It’s my safe space: The life-saving role of the internet in the lives of transgender and gender diverse youth

Abstract

Background: Public awareness of Transgender and Gender Diverse (TGD) identities has grown significantly; however, acceptance and support remain elusive for many TGD youth. Resultant experiences of marginalization and stigmatization contribute to elevated rates of psychological distress and suicidality among TGD youth. Emergent evidence suggests that the internet may offer TGD youth safety, support, and community previously unavailable.

Aim: The primary aim of this qualitative inquiry is to engage in an in-depth exploration of the online experiences and processes which help protect against psychological distress and promote well-being among TGD youth.

Methods: Data were culled from a mixed-methods, online study of sexual and gender minority youth from across the United States and Canada which followed Institutional Review Board approved protocols. Participants for this study represent a sample (n?=?260) of TGD participants aged 14–22 (x? = 17.30). Data were analyzed using Charmaz’ grounded theory strategies.

Results: Data revealed that the internet offers TGD youth affirming spaces that, for the most part, do not exist in their offline lives. Online, TGD youth were able to engage meaningfully with others as their authentic selves, often for the first time. These experiences fostered well-being, healing, and growth through five processes: 1. Finding an escape from stigma and violence, 2. Experiencing belonging, 3. Building confidence, 4. Feeling hope, and 5. Giving back.

Discussion: The unique and innovative ways in which participants use online spaces to foster resilience offer important insights to inform affirmative practices with TGD young people.     

“White Skin”: Lyotard’s Sketch of a Postcolonial Libidinal Economy

ABSTRACT

In 1975 Jean-François Lyotard published a short text entitled Pacific Wall. A mash-up of philosophy, fiction, biography, and art criticism, it is highly gnomic if read in isolation. Studied alongside other works from this period, however, it may be understood as sketching a postcolonial libidinal economy. The book’s central concept, “white (or blank) skin” avoids any simple identification and instead expresses a series of permutations of desire in relation to race and sex: it is equally the skin of white heterosexual women and of black homosexual men; equally the otherness at the borders of capital’s expansion and the supposed identity at the heart of Empire. Lyotard suggests that political issues endemic to the postcolonial situation may be understood in terms of feelings such as lust, jealousy, fear, and the desire for revenge, and that these circulate and mutate along with the flows and transformations of capital.     

An Examination of Historical Loss Thinking Frequency and Rumination on Suicide Ideation in American Indian Young Adults

No research has empirically investigated whether frequency of historical loss thinking is a potential risk factor for suicide ideation in American Indians. Results of this study demonstrated that the frequency of historical loss thinking was positively associated with brooding and reflection at a small magnitude, but was not directly related to suicide ideation. Bootstrapping analyses indicated small indirect effects of historical loss thinking frequency on suicide ideation through brooding and reflection individually, but only through brooding when analyzed in a parallel mediation model. These findings suggest that American Indians who more frequently engage in historical loss thinking may be susceptible to suicide ideation via an increase in ruminative tendencies, specifically brooding.
