Youth sports and physical activity: The relationship between perceptions of childhood sport experience and adult exercise behavior

ObjectiveParticipation in organized youth sports has been shown to positively correlate with increased levels of exercise in adulthood. However, there is limited research to suggest why youth sports participation is related to increased physical activity as an adult. One possible explanation is that positive youth sport experiences lead youth to be more positively inclined to engage in physical activity as adults. Research into the positive youth development aspect of organized sports provides the framework for the current investigation.MethodsAdult participants (N = 234, M_age = 35.35) were asked to retrospectively assess their youth sports experiences using the “Four C's” (i.e., competence, confidence, connectedness, character) framework of positive youth development in sport. These assessments were then compared to current physical activity levels and related variables found in the Health Action Process Approach model (HAPA; Schwarzer, 2008).ResultsBivariate correlations revealed statistically significant and moderate correlations among competence, confidence, and connectedness and all of the HAPA variables including physical activity levels. Further, a MANCOVA analysis revealed that when participants were sub-divided into “non-intenders,” “intenders,” and “actors” using a validated staging algorithm, a general linear trend emerged for competence, confidence, and connectedness such that “non-intenders” rated these constructs the lowest and “actors” rated them the highest.ConclusionThese findings provide preliminary evidence that the relationship between participation in organized youth sports and adulthood levels of exercise could be contingent on how positively that experience is perceived.     

A pilot study exploring the use of a telephone-assisted planning intervention to promote parental support for physical activity among children and youth with disabilities

Parent support is an important contributor to physical activity (PA) among children and youth with disabilities (CYD). Although many parents of CYD are motivated to provide parent PA support, CYD remain insufficiently active. The multi-process action control model has been applied to understand parent PA support and highlights behavioral regulation strategies such as action and coping planning as critical for translating intentions into behavior. Parents may struggle to create and carryout planning without support. There is no known research examining telephone support as a tool to promote planning and subsequent parent PA support behavior.MethodParents (43 mothers and 6 fathers) of CYD (child M_age = 12.53 years ± 5.53; 75% male; 38.6% developmental disability) completed a baseline questionnaire and were subsequently randomized to a telephone-assisted planning experimental group twice over four weeks (n = 23) or a control group who had access to planning tools but no telephone assistance (n = 26).ResultsNo significant main or interaction effects emerged for parent PA support behavior. However, a significant time × condition interaction was found for behavioral regulation strategies (i.e., action and coping planning and self-monitoring; F(1,44) = 5.05, p = 0.03) indicating a significant increase in the use of behavioral regulation strategies for parent PA support from baseline, for parents assigned to the telephone-assisted intervention.ConclusionThese findings suggest potential for planning support as a tool to enhance behavioral regulation strategies related to parent PA support among parents of CYD.     

“I deserve a treat”: Exercise motivation as a predictor of post-exercise dietary licensing beliefs and implicit associations toward unhealthy snacks

ObjectiveTo explore whether exercise motivation predicted two of the potential mechanisms that may explain why individuals engage in unhealthy compensatory snack consumption following exercise; specifically (a) post-exercise conscious licensing beliefs, and (b) post-exercise implicit attitudes toward unhealthy snacks.DesignObservational study.MethodOne hundred and nineteen healthy participants completed a 40-min session of moderate intensity stationary cycling, and subsequently completed measures of explicit licensing and implicit associations toward unhealthy snack foods and drinks.ResultsIndividuals driven by more controlled (relative to autonomous) forms of exercise motivation reported greater compensatory licensing beliefs (Est = −0.08, p < 0.001) even after accounting for a number of relevant covariates. No significant relationship emerged between exercise motivation and implicit associations toward unhealthy snacks (Est = 0.12, p = 0.81).ConclusionThe findings demonstrate that exercise motivation may predict conscious licensing beliefs toward unhealthy snack foods and drinks post-exercise. Understanding the modifiable factors – such as exercise motivation – that predict post-exercise dietary beliefs is important for supporting individuals’ weight loss and health goals.     

Eye tracking reveals the cost of switching between self and other perspectives in a visual perspective-taking task

Previous studies have shown that while people can rapidly and accurately compute their own and other people’s visual perspectives, they experience difficulty ignoring the irrelevant perspective when the two perspectives differ. We used the “avatar” perspective-taking task to examine the mechanisms that underlie these egocentric (i.e., interference from their own perspective) and altercentric (i.e., interference from the other person’s perspective) tendencies. Participants were eye-tracked as they verified the number of discs in a visual scene according to either their own or an on-screen avatar’s perspective. Crucially in some trials the two perspectives were inconsistent (i.e., each saw a different number of discs), while in others they were consistent. To examine the effect of perspective switching, performance was compared for trials that were preceded with the same versus a different perspective cue. We found that altercentric interference can be reduced or eliminated when participants stick with their own perspective across consecutive trials. Our eye-tracking analyses revealed distinct fixation patterns for self and other perspective taking, suggesting that consistency effects in this paradigm are driven by implicit mentalizing of what others can see, and not automatic directional cues from the avatar.     

Are you looking my way? Ostracism widens the cone of gaze

Ostracized individuals demonstrate an increased need for belonging. To satisfy this need, they search for signals of inclusion, one of which may be another person’s gaze directed at oneself. We tested if ostracized, compared to included, individuals judge a greater degree of averted gaze as still being direct. This range of gaze angles still viewed as direct has been dubbed “the cone of (direct) gaze”. In the current research, ostracized and included participants viewed friendly-looking face stimuli with direct or slightly averted gaze (0°, 2°, 4°, 6°, and 8° to the left and to the right) and judged whether stimulus persons were looking at them or not. Ostracized individuals demonstrated a wider gaze cone than included individuals.     

Anticipation measures of sequence learning: manual versus oculomotor versions of the serial reaction time task

The serial reaction time (SRT) task has generated a very large amount of research. Nevertheless the debate continues as to the exact cognitive processes underlying implicit sequence learning. Thus, the first goal of this study is to elucidate the underlying cognitive processes enabling sequence acquisition. We therefore compared reaction time (RT) in sequence learning in a standard manual activated (MA) to that in an ocular activated (OA) version of the task, within a single experimental setting. The second goal is to use eye movement measures to compare anticipation, as an additional indication of sequence learning, between the two versions of the SRT. Performance of the group given the MA version of the task (n = 29) was compared with that of the group given the OA version (n = 30). The results showed that although overall, RT was faster for the OA group, the rate of sequence learning was similar to that of the MA group performing the standard version of the SRT. Because the stimulus-response association is automatic and exists prior to training in the OA task, the decreased reaction time in this version of the task reflects a purer measure of the sequence learning that occurs in the SRT task. The results of this study show that eye tracking anticipation can be measured directly and can serve as a direct measure of sequence learning. Finally, using the OA version of the SRT to study sequence learning presents a significant methodological contribution by making sequence learning studies possible among populations that struggle to perform manual responses.     

How young adults with autism spectrum disorder watch and interpret pragmatically complex scenes

The aim of the current study was to investigate subtle characteristics of social perception and interpretation in high-functioning individuals with autism spectrum disorders (ASDs), and to study the relation between watching and interpreting. As a novelty, we used an approach that combined moment-by-moment eye tracking and verbal assessment. Sixteen young adults with ASD and 16 neurotypical control participants watched a video depicting a complex communication situation while their eye movements were tracked. The participants also completed a verbal task with questions related to the pragmatic content of the video. We compared verbal task scores and eye movements between groups, and assessed correlations between task performance and eye movements. Individuals with ASD had more difficulty than the controls in interpreting the video, and during two short moments there were significant group differences in eye movements. Additionally, we found significant correlations between verbal task scores and moment-level eye movement in the ASD group, but not among the controls. We concluded that participants with ASD had slight difficulties in understanding the pragmatic content of the video stimulus and attending to social cues, and that the connection between pragmatic understanding and eye movements was more pronounced for participants with ASD than for neurotypical participants.     

Human gestures trigger different attentional shifts in chimpanzees (Pan troglodytes) and humans (Homo sapiens)

Brain lateralization has been the matter of extensive research over the last centuries, but it remains an unsolved issue. While hand preferences have been extensively studied, very few studies have investigated laterality of eye use in non-human primates. We examined eye preference in 14 Campbell’s monkeys (Cercopithecus c. campbelli). We assessed eye preference to look at a seed placed inside a tube using monocular vision. Eye use was recorded for 100 independent and non-rewarded trials per individual. All of the 14 monkeys showed very strong preferences in the choice of the eye used to look inside the tube (mean preference: 97.6%). Eight subjects preferred the right eye and six subjects preferred the left eye. The results are discussed in light of previous data on eye preference in primates, and compared to data on hand preference from these subjects. Our findings would support the hypothesis for an early emergence of lateralization for perceptual processes compared to manual motor functions.     

The Effects of Social Identity and Perceived Autonomy Support on Health Behaviour Within the Theory of Planned Behaviour

The present study employed constructs from self-determination theory, social-identity theory, and the theory of planned behaviour to examine the combined effects that social identity and perceived autonomy support exerted on attitudes, intentions and health behaviour. A prospective design was employed measuring constructs from the theory of planned behaviour, group norms, group identification, and perceived autonomy support at baseline and physical activity behaviour 5 weeks later. Self-report questionnaires were administered to 231 pupils (male = 113, female = 118, M = 14.21 years, SD = .90). Hierarchical regression analysis demonstrated that group norms predicted participation in physical activities and attitudes, but only for participants who identified strongly with their group. Perceived autonomy support predicted attitudes, intentions and behaviour. The effects of perceived autonomy support and social-identity constructs were independent. It was concluded that both social identity and perceived autonomy support should be included in the theory of planned behaviour.     

Learning to attend: a connectionist model of situated language comprehension

Evidence from numerous studies using the visual world paradigm has revealed both that spoken language can rapidly guide attention in a related visual scene and that scene information can immediately influence comprehension processes. These findings motivated the coordinated interplay account ( Knoeferle & Crocker, 2006 ) of situated comprehension, which claims that utterance-mediated attention crucially underlies this closely coordinated interaction of language and scene processing. We present a recurrent sigma-pi neural network that models the rapid use of scene information, exploiting an utterance-mediated attentional mechanism that directly instantiates the CIA. The model is shown to achieve high levels of performance (both with and without scene contexts), while also exhibiting hallmark behaviors of situated comprehension, such as incremental processing, anticipation of appropriate role fillers, as well as the immediate use, and priority, of depicted event information through the coordinated use of utterance-mediated attention to the scene.
