Pigeons’ memory for event duration: Intertrial interval and delay effects

The effects of within-session variations in the intertriai interval (ITI) and delay on pigeons’ memory for event duration were studied in delayed symbolic matching-to-sample tasks. Pigeons were trained to peck one color following a long (8 sec) sample and another color following a short (2 sec) sample. In the first three experiments, the baseline conditions included a 10-sec delay (retention interval) and a 45-sec ITI. During testing, the delay was varied from 0 to 20 sec, and the ITI that preceded the trial was varied from 5 to 90 sec. When the ITI and delay were manipulated separately (Experiments 1 and 2), the pigeons displayed a choose-short tendency when the delay was longer than 10 sec or when the ITI was longer than 45 sec, and a choose-long tendency when either the delay or the ITI was shorter than these baseline values. These effects occurred whether the sample was food access or light. When the ITI and delay were manipulated together, the pigeons showed a large choose-long error tendency when the short delay was tested together with a short ITI, and no systematic error tendency when the short delay was tested together with a longer ITI. A very large choose-short error tendency emerged on trials with a long delay and a long ITI; a reduced choose-short tendency was present when the long delay was presented together with a short ITI. In Experiment 4, the baseline conditions were a 0-sec delay and a 45-sec ITI. In this case variations in the ITI had a smaller and unidirectional effect: the pigeons showed a choose-long error tendency when the ITI was decreased, but no effect of ITI increases. Two hypotheses were proposed and discussed: (1) that pigeons judge sample durations relative to a background time composed of the ITI and delay, and (2) that the delay and ITI effects might arise from a combination of subjective shortening and proactive effects of samples from previous trials.     

Improving Campus Climate to Support Faculty Diversity and Retention: A Pilot Program for New Faculty

We report on a series of pilot programs that we developed and carried out to support the success and satisfaction of new faculty, particularly faculty of color. We hope that others committed to retaining and supporting underrepresented faculty can apply our learning from this pilot project, as a whole or in part.Fred P.

Comprehensive Sexuality Education for Adolescents in Zambia via the Mobile-Optimized Website TuneMe: A Content Analysis

Abstract

Adolescents in sub-Saharan Africa encounter high risks associated with sexuality and reproduction, yet face numerous barriers in obtaining appropriate health services and information. Mobile phones provide a unique opportunity to provide youth with this critical sexual and reproductive health information need. Designed from the United Nations Comprehensive Sexuality Education framework, the mobile-optimized app TuneMe aims to provide adolescents living in eight sub-Saharan African countries—Zambia, Malawi, Zimbabwe, Swaziland, Lesotho, South Africa, Botswana, and Namibia—with sexual and reproductive health information, and to promote uptake and use of sexual and reproductive health services. To assess the scope and appropriateness of TuneMe’s sexuality education content, we conducted a directed content analysis of the 299 articles published on the Zambia-specific TuneMe site between October 2015 and June 2017. Results from this analysis indicate that the greatest information provided by TuneMe was on sexual and reproductive health and HIV, followed by relationships, sexual rights, and citizenship. There was substantially less information that focused specifically on matters of pleasure, violence, diversity, and gender. Content was situated within relatable and culturally-relevant contexts, but gave mixed, and often problematic, depictions of gender norms. This assessment is central to understanding current and future mobile-based sexuality education programming.

Global channels of evidence for learning and assessment in complex game environments

In this paper, we take a designer's look at how the activities and data of learning and assessment can be structured in immersive virtual game environments called Massively Multi‐Player Online Games (MMOG). In doing so, we examine the channels of evidence through which learning and assessment activities are derived in MMOGs, offering examples of how multiple evidence channels in operation through game‐based activities can be utilised to construct rich data trails for assessment.     

Potential for teacher collaboration in post-Soviet Ukraine

The purpose of this conceptual paper is to analyze the potential for collaborative relationships in schools in Ukraine. In this paper, I examine the nature of teacher collaboration in schools within a framework of postmodernism as a constructive social theory. To better grasp the deep meaning of collaborative interactions in schools, I use cultural and micropolitical perspective. Further, I turn to the discussion of the potential for collaboration in Ukrainian schools, utilizing the notion of a collective that prevailed in Soviet society and system of education. Implications for establishing collaborative school cultures in Ukraine conclude the paper.     

Relationships between functional movement screen scores,maturation and physical performance in young soccer players

The purpose of this study was to examine relationships between functional movement screen scores, maturation and physical performance in young soccer players. Thirty males (11–16 years) were assessed for maturation, functional movement screen scores and a range of physical performance tests (squat jump, reactive strength index protocol and reactive agility cut). Older players significantly outperformed younger participants in all tests (P < 0.05; effect sizes = 1.25–3.40). Deep overhead squat, in-line lunge, active straight leg raise and rotary stability test were significantly correlated to all performance tests. In-line lunge performance explained the greatest variance in reactive strength index (adjusted R² = 47%) and reactive agility cut (adjusted R² = 38%) performance, whilst maturation was the strongest predictor of squat jump performance (adjusted R² = 46%). This study demonstrated that variation of physical performance in youth soccer players could be explained by a combination of both functional movement screen scores and maturation.     

The development of a method for identifying penalty kick strategies in association football

Penalty takers in association football adopt either a keeper-independent or a keeper-dependent strategy, with the benefits of the keeper-independent strategy presumed to be greater. Yet, despite its relevance for research and practitioners, thus far no method for identifying penalty kick strategies has been available. To develop a validated and reliable method, Experiment 1 assessed characteristics that observers should use to distinguish the two strategies. We asked participants to rate 12 characteristics of pre-recorded clips of kicks of penalty takers that used either a keeper-independent or keeper-dependent strategy. A logistic regression model identified three variables (attention to the goalkeeper, run-up fluency and kicking technique) that in combination predicted kick strategy in 92% of the penalties. We used the model in Experiment 2 to analyse prevalence and efficacy of both the strategies for penalty kicks in penalty shoot-outs during FIFA World Cups (1986–2010) and UEFA Football Championships (1984–2012). The keeper-independent strategy was used much more frequently (i.e., 78–86%) than the keeper-dependent strategy, but successes did not differ. Penalty takers should use both the strategies to be less predictable. Goalkeepers can use the developed model to improve their chances to succeed by adjusting their behaviour to penalty takers’ preferred penalty kick strategy.
