Exploring Perceptions of Group Processes in Ice Hockey Officiating

Understanding factors that influence sport officials' performance is vital to ensuring fair sport competition. Through semistructured interviews (N = 17), we explored officials' perceptions of group processes that occurred among ice hockey officiating teams. Participant responses revealed numerous ways that group processes were present within officials' interactions, and two unique characteristics involved the transient nature of officiating groups (frequently performing with different officials) and intrateam competition pertaining to postseason assignments. In the discussion, we expand on the unique nature of officiating groups, synthesize activities in which officials seek to enhance groupness, and provide insights for future interventions and researchers.     

Student outcomes after 1 year of front line staff implementation of the PEAK curriculum

Systems‐level interventions built by behavior analysts often rely on others to implement, and this may be especially true in public education settings where behavior analysts are scarce. This study evaluated the effectiveness of the Promoting the Emergence of Advanced Knowledge Direct Training (PEAK‐DT) curriculum when implemented by school teachers and direct care staff. Thirty‐nine children with autism took part in the study (19 PEAK, 15 control), where the experimental group received applied behavior analytic instruction through the PEAK‐DT curriculum, and the quasi‐randomized control group received training as usual. The PEAK‐DT assessment was first administered to the participants at the onset of the study and again following 1 year. Participants who received PEAK training gained more skills on the PEAK‐DT assessment compared to the control group (PEAK: M = 16.0, SD = 17.8; control: M = 6.1, SD = 14.4, F(1,33) = 10.66, p < .05), suggesting that systems level implementation of behavior analytic procedures can be effective in teaching language skills as prescribed in a packaged curriculum designed by behavior analysts.     

Electrophysiological correlates of encoding processes in a full-report visual working memory paradigm

Why are some visual stimuli remembered, whereas others are forgotten? A limitation of recognition paradigms is that they measure aggregate behavioral performance and/or neural responses to all stimuli presented in a visual working memory (VWM) array. To address this limitation, we paired an electroencephalography (EEG) frequency-tagging technique with two full-report VWM paradigms. This permitted the tracking of individual stimuli as well as the aggregate response. We recorded high-density EEG (256 channel) while participants viewed four shape stimuli, each flickering at a different frequency. At retrieval, participants either recalled the location of all stimuli in any order (simultaneous full report) or were cued to report the item in a particular location over multiple screen displays (sequential full report). The individual frequency tag amplitudes evoked for correctly recalled items were significantly larger than the amplitudes of subsequently forgotten stimuli, regardless of retrieval task. An induced-power analysis examined the aggregate neural correlates of VWM encoding as a function of items correctly recalled. We found increased induced power across a large number of electrodes in the theta, alpha, and beta frequency bands when more items were successfully recalled. This effect was more robust for sequential full report, suggesting that retrieval demands can influence encoding processes. These data are consistent with a model in which encoding-related resources are directed to a subset of items, rather than a model in which resources are allocated evenly across the array. These data extend previous work using recognition paradigms and stress the importance of encoding in determining later VWM retrieval success.     

Recognition memory performance as a function of reported subjective awareness

Three experiments introduced a recognition memory paradigm designed to investigate reported subjective awareness during retrieval. At study, in Experiments 1A and 2, words were either generated or read (generation), while modality of presentation (auditory versus visual) was manipulated in Experiment 1B. Word pairs (old/new or new/new) were presented during test trials, and participants indicated if they contained an old word by responding "remember", "know" or "new" in Experiments 1A and 1B, and by responding "strong no", "weak no", "weak yes", or "strong yes" in Experiment 2. Participants were then required to decide which of the 2 words was old. We demonstrated that the proportion measures used in the Remember Know paradigm substantially underestimated the influence of generation on familiarity resulting in an artificial dissociation between indices of knowing (familiarity) and remembering (recollection). We also found a qualitatively different pattern of forced-choice recognition performance as a function of claimed awareness.     

The Current State of Intervention Research for Posttraumatic Stress Disorder Within the Primary Care Setting

Posttraumatic Stress Disorder (PTSD) is common among primary care patients and is associated with significant functional impairment, physical health concerns, and mental health comorbidities. Significant barriers to receiving adequate treatment often exist for primary care patients with PTSD. Mental health professionals operating as part of the primary care team have the potential to provide effective brief intervention services. While good PTSD screening and assessment measures are available for the primary care setting, there are currently no empirically supported primary care-based brief interventions for PTSD. This article reviews early research on the development and testing of primary care-based PTSD treatments and also reviews other brief PTSD interventions (i.e., telehealth and early intervention) that could be adapted to the primary care setting. Cognitive and behavioral therapies currently have the strongest evidence base for establishing an empirically supported brief intervention for PTSD in primary care. Recommendations are made for future research and clinical practice.     

Follow your heart: Emotion adaptively influences perception

The current review introduces a new program of research that suggests the perception of spatial layout is influenced by emotions. Though perceptual systems are often described as closed and insulated, this review presents research suggesting that a variety of induced emotions (e.g., fear, disgust, sadness) can produce changes in vision and audition. Thus, the perceptual system may be highly interconnected, allowing emotional information to influence perceptions that, in turn, influence cognition. The body of work presented here also suggests that emotion-based changes in perception help us solve particular adaptive problems because emotion does not change all perceptions of the world. Taking the adaptive significance of emotion into account allows us to make predictions about when and how emotion influences perception.     

Development of an ethanol model using social insects: III. Preferences for ethanol solutions

Experiments are designed to assess whether free-flying honey bees have an aversion to an ethanol solution when given a choice between targets containing an ethanol solution in sucrose or sucrose only. Animals given a choice between a 1% ethanol solution and sucrose only show no aversion to the ethanol solution either in acquisition or extinction. Honey bees given a choice between a 5% ethanol solution and sucrose only show no differences in the initial choice of targets but some ees do switch over to the sucrose-only target. Performance during extinction indicates that bees landed on the previously reinforced sucrose-only target more than the target previously containing the 5% ethanol solution. An experiment in which bees were given a single 5%, ethanol target showed that of 20 bees, 11 returned for the entire 12 trials of the experiment. All bees returned at least 6 times to the 5% ethanol target. Additional experiments were run on harnessed foragers in a palatability study of alcoholic beverages consumed by humans. The results of the palatability experiment indicate that in general, bees prefer more sweet drinks with less alcohol.     

Infants learn phonotactic regularities from brief auditory experience

Two experiments investigated whether novel phonotactic regularities, not present in English, could be acquired by 16.5-month-old infants from brief auditory experience. Subjects listened to consonant-vowel-consonant syllables in which particular consonants were artificially restricted to either initial or final position (e.g. /baep/ not /paeb/). In a later head-turn preference test, infants listened longer to new syllables that violated the experimental phonotactic constraints than to new syllables that honored them. Thus, infants rapidly learned phonotactic regularities from brief auditory experience and extended them to unstudied syllables, documenting the sensitivity of the infant's language processing system to abstractions over linguistic experience.     

Measuring transactive memory systems in the field: scale development and validation

This study describes the development and validity testing of a field measure of transactive memory systems. Transactive memory systems are especially important for teams designed to leverage members' expertise, but field research has lagged because there are no adequate measures of the construct. The author developed and tested a 15-item scale in a laboratory sample of 124 teams, a field sample of 64 Master of Business Administration consulting teams, and a field sample of 27 teams from technology companies. Results from the present study demonstrate that the scale is internally consistent, related to alternative measures and hypothesized causes and effects, and unrelated to theoretically distinct constructs, providing evidence of convergent, criterion-related, and discriminant validity. Suggestions for improving the scale, future validity testing, and possible boundary conditions are discussed.
