Using MATLAB with the Psychophysics Toolbox to present the heterochromatic fusion nystagmus stimulus

We present a program for MATLAB that generates and presents theheterochromatic fusion nystagmus stimulus. This stimulus allows assessment of isoluminant states through recordings of reflexive eye movements (optokinetic nystagmus). The reflexive nature of the subject’s response makes this stimulus especially useful with nonverbal subjects, such as children and animals. Unfortunately, the stimulus is complex and difficult to program. By presenting the present program, we hope to help those who wish to use this tool in their research. The code of the function can be downloaded at www. dal.ca/~mcmullen/downloads.html.     

How do I see myself? A systematic review of identities in pro‐environmental behaviour research

Encouraging pro‐environmental behaviour (PEB) is an environmental and societal concern. Encouraging PEB focussing on how consumers see themselves (their identity) has blossomed. However, a theoretical assessment of this research is missing. Three main identity theories seem to best explain the research, specifically, and two‐fold, identity, and social identity theory (SIT), collectively known as the unified identity theory (UIT), and place identity theory (PIT). As these theories overlap more than differ in their understanding of identity, we argue that combining these theories is needed to avoid redundancies in identity theorizing, provide a universal approach to identity in terms of the processes and outcomes, and explain the PEB research most succinctly. Therefore, we understand identity similarly between the theories and offer a universal identity theory approach based on the theoretical definitions and assumptions. Finally, we demonstrate how the theory can be used to explain the research. Next, research was identified by conducting a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines, where 62 studies were relevant. Multiple identities relevant for a given PEB are assumed and evidenced: 99. Identities are assumed to be either individually‐, group‐, and/or place‐focused, drawing on the specific subsets of the universal theory: identity theory, social identity theory, and place identity theory, respectively. Identities are assumed to relate to behaviour, where identity increased PEB with medium effect sizes. Finally, to move the field forward, we provide a theoretical framework of how to test identities in relation to other psychological variables relevant for PEB research.     

Development of species identification in ducklings: II. Experimental prevention of perceptual deficit caused by embryonic auditory deprivation.

Devocalized-isolated ducklings are relatively insensitive to the higher frequencies in their species' maternal call 24 hr after hatching. To assess the efficacy of various sounds in preventing this high-frequency perceptual deficit, devocalized-isolated embryos were exposed to one of three calls and tested with normal versus high-frequency attenuated maternal calls 24 hr after hatching. The embryonic vocalization (contact-contentment call) that most closely matched the region of the devocalized ducklings' greatest insensitivity (1,500-2,500 Hz) proved most efficacious in remedying (preventing) the high-frequency perceptual deficit. Exposure to the embryonic alarm-distress call was somewhat effective, whereas exposure to low-frequency white noise was not effective at all. This finding suggests that the normal development of innate behavior is partially dependent upon prior experience as well as upon intrinsic processes of neural maturation. Although normally occurring embryonic auditory experience does not induce the preference for the maternal call in this species, such experience does contribute to the sharpness of the discriminative basis of the preference 24 hr after hatching.     

The Politics of Biometric Standards: The Case of Israel Biometric Project

In 2017, after years of public debate, Israel ratified a national biometric project consisting of two initiatives: issuing of biometric ID cards and passports to all Israeli citizens and establishment of a centralized database for storing their bodily information. Design and implementation of a preceding four-year pilot study were accompanied by extensive standardization. Discourse and standard analyses of 33 official state documents – from legal records to performance reports – published by Israeli authorities during the pilot study, unravel the politics of biometric standards employed as part of this project. Biometric standards were used to establish hierarchies between individuals and groups by defining particular bodies as ‘biometrically ineligible.’ These individuals are mostly members of underprivileged and marginalized social groups. Biometric standards were also constructed discursively as scientific and objective to legitimize such discriminatory treatment. Israeli authorities used standards strategically, both as infrastructural elements and as a discursive means. As infrastructural elements, biometric standards were employed, inter alia, to achieve predetermined results and confirm the project’s success. As a discursive means, Israeli authorities actively adopted a ‘discourse of standardization’ to construct an objective and fair image to the project. Standardization of people – namely, quantification of lives, bodies and experiences – is inherently discriminatory because it necessarily results in the creation of categories and hierarchies between biometrically in/eligible bodies.     

Statewide Implementation of Cognitive Behavioral Therapy for Psychosis Through a Learning Collaborative Model

Cognitive Behavioral Therapy for Psychosis (CBTp) is an evidence-based psychotherapeutic intervention (EBPI) for adults with schizophrenia spectrum disorders that remains under-implemented in the United States (U.S.). There has been little empirical attention on implementation and dissemination strategies for this EBPI. The Learning Collaborative (LC) model is a method of implementing evidence-based practices across agencies and geographic regions that may facilitate CBTp implementation and dissemination in the US.We applied the LC model in an attempt to enhance the accessibility of CBTp in community mental health settings statewide. Providers (N = 56) from 12 agencies voluntarily participated in an in-person, CBTp workshop followed by 6 months of biweekly phone-based consultation sessions (Phase 1). Twenty-one providers opted to participate in an additional 6-month CBTp LC immediately following completion of the initial CBTp LC (Phase 2). Adoption, penetration, provider-perceived skill development, fidelity, as well as provider-perceived implementation barriers were re-assessed during and 6 months after completion of Phase 2.One year after the completion of the Phase 2 LC, 21% of the original trainee group across 3 of the 12 participating agencies continued to offer CBTp to clients. CBTp trainees were treating between one and two clients each. Self-assessed CBTp skills improved modestly over the Phase 2 consultation period. On average, both clinicians and supervisors reached an acceptable fidelity score on the sessions reviewed. Participating providers identified multiple barriers to CBTp implementation, including features of the training and consultation, the agency, the intervention itself, and psychosocial and clinical challenges associated with the client population.Few CBTp implementation studies have applied a framework to CBTp implementation. The authors adapted the LC model in an attempt to promote adoption of CBTp in community mental health clinics across a large, populous state with poor access to mental health services. Identified challenges and recommendations should be considered in future implementation efforts.     

The Politics of Religious Heritage: Framing Claims to Religion as Culture in Spain

This article contributes to sociological theorizations of religion as heritage through analyzing the politics of religious heritage in Spain since its transition to democracy during the late 1970s. Our analysis is organized around three historical sequences of critical importance for understanding the political and legal significance of discourses that frame religion as cultural heritage in Spain: (1) negotiations that took place during Spain's democratic transition between 1977 and 1980; (2) discussions that surfaced in the context of the state's decision to recognize Islam, Protestantism, and Judaism in 1992; and (3) more recent debates regarding the incorporation of religious minorities in the context of increasing religious diversity, especially concerning places of worship. We show how framing “religion” using the language of cultural heritage has provided religious actors with a means of defending the connection between religion and national identity—and of protecting the privileges of majoritarian religious institutions without violating core tenets of secularism or pluralism. This scenario has created space for certain religious minorities to claim a place within Spain's evolving socioreligious landscape by invoking alternative heritages from Spain's multicultural past.     

Perfectionistic self-presentation in children and adolescents: development and validation of the Perfectionistic Self-Presentation Scale--Junior Form

Research on adults indicates that perfectionistic self-presentation, the interpersonal expression of one's perfection, is associated with a variety of psychopathological outcomes independent of trait perfectionism and Big Five traits. The current article reports on the development and evidence for the validity of the subtest score interpretations of an 18-item self-report measure of perfectionistic self-presentation for children and adolescents. Analyses conducted on data from two clinical samples and one nonclinical sample of children and adolescents found that the Perfectionistic Self-Presentation Scale--Junior Form (PSPS-Jr) reflected a multidimensional model of perfectionistic self-presentation with three subscales: Perfectionistic Self Promotion, Nondisplay of Imperfection, and Nondisclosure of Imperfection. The subscale scores were found to demonstrate internal consistency, and there was good evidence supporting the validity of the interpretation of subscale scores based on this new measure. The subscales were associated with maladaptive outcomes, but were not influenced unduly by biases that included social desirability and differential item functioning by gender. Overall, the PSPS-Jr appears to be a useful measure of the expression of perfection among youths and an important tool in attempting to understand the nature and the consequences of perfectionistic self-presentation in children and adolescents.
