Reducing Excessive Television Viewing While Increasing Physical Activity

One family participated in a study evaluating the effectiveness of a product aimed at reducing television viewing by providing television viewing time in exchange for bicycle riding. The device, called Control-the-TV, is comprised of a control box which attaches to the electrical cord of a television set, and two sensors which attach to the wheel and corresponding wheel rim of a stationary bicycle. It has a locking device, accessible only by a key, which secures the control box from tampering. The child in this study was required to ride the bicycle for 15 minutes to earn 30 minutes of television viewing time. The parents were instructed to record the total number of hours of TV viewed by the target child during an initial 20 day baseline and a 30 day intervention period. Results suggest that Control-the-TV can be effective in reducing time spent viewing television.     

What Produces Television Attention and Attention Style?

Individual looks at television vary enormously in length, and this has previously indicated differences in ongoing cognitive processes. Furthermore, the relative frequency of looks of different lengths may indicate styles of attention to television. This article compares visual attention of 152 subjects across a variety of genres and examines differences located by situation, person, and media perception variables. Attention style was not consistent for individuals but varied for different types of programming and between‐program breaks. Situational, person, and media belief variables did not predict the proportions of four types of looks. They did, however, predict differences in the proportion of moderately short (orienting) looks across types of content, but not the previously more important very short (monitoring) or moderately long (engaged) looks. The overall importance of type of content in these results suggests that further research should examine within‐program differences in message construction and assess attentional style as patterns or sequences of looks.     

Curious Objects: How Visual Complexity Guides Attention and Engagement

Some things look more complex than others. For example, a crenulate and richly organized leaf may seem more complex than a plain stone. What is the nature of this experience—and why do we have it in the first place? Here, we explore how object complexity serves as an efficiently extracted visual signal that the object merits further exploration. We algorithmically generated a library of geometric shapes and determined their complexity by computing the cumulative surprisal of their internal skeletons—essentially quantifying the “amount of information” within each shape—and then used this approach to ask new questions about the perception of complexity. Experiments 1–3 asked what kind of mental process extracts visual complexity: a slow, deliberate, reflective process (as when we decide that an object is expensive or popular) or a fast, effortless, and automatic process (as when we see that an object is big or blue)? We placed simple and complex objects in visual search arrays and discovered that complex objects were easier to find among simple distractors than simple objects are among complex distractors—a classic search asymmetry indicating that complexity is prioritized in visual processing. Next, we explored the function of complexity: Why do we represent object complexity in the first place? Experiments 4–5 asked subjects to study serially presented objects in a self-paced manner (for a later memory test); subjects dwelled longer on complex objects than simple objects—even when object shape was completely task-irrelevant—suggesting a connection between visual complexity and exploratory engagement. Finally, Experiment 6 connected these implicit measures of complexity to explicit judgments. Collectively, these findings suggest that visual complexity is extracted efficiently and automatically, and even arouses a kind of “perceptual curiosity” about objects that encourages subsequent attentional engagement.     

Memory for Sexual and Nonsexual Television Commercials as a Function of Viewing Context and Viewer Gender

The present study investigated memory for sexual and nonsexual commercials as a function of programme‐commercial congruity and programme‐induced level of involvement. Participants were allocated to one of four conditions: sexual programme with sexual or nonsexual commercials and nonsexual programme with sexual or nonsexual commercials. Recall and involvement levels were tested with a series of memory tests and programme ratings. It was predicted that sexual advertisements would be recalled and recognised better overall, that the sexual programme context would impair memory for commercials, and that level of involvement with the programme would inversely correlate with recall and recognition of the commercials and their content. Recall of sexual advertisements was found to be better than for nonsexual advertisements, and subjective ratings of programme involvement were higher for the sexual programme. Neither the perceived involvement level nor programme type affected memory for the commercials overall, but men were shown to remember sexual advertisements better than nonsexual advertisements—particularly when the sexual advertisements were embedded in a sexual programme. Women were equally good at remembering sexual and nonsexual advertisements. Implications of the current results and suggestions for future research are discussed.

Predispositional Engagement,Activity Engagement,and Cognition among Older Adults

ABSTRACT

We investigated interrelationships between the predisposition toward approaching experiences in a mindful and creative way, participation in specific activities, and cognition among older adults. Participants were administered a battery measuring cognition (i.e., working memory, processing speed, divergent thinking, inductive reasoning, visuo-spatial processing), activity level, and the predisposition towards mental engagement (Need for Cognition, Mindfulness, and Openness to Experience). Results indicated that predispositional engagement and activity engagement are distinct constructs that independently contribute to different aspects of fluid ability, highlighting the importance of considering both the predisposition toward mental engagement as well as the habitual tendency to participate in activities when exploring principles of cognitive optimization.     

Emotional Reactions While Watching Graphic Medical Procedures: Vocational Differences in the Explicit Regulation of Emotions1

We examined the role of occupation in how people regulate emotional responses. Graduate nursing students were compared to undergraduate psychology students on self‐reported emotional reactions to videos depicting graphic medical procedures. Skin conductance was also recorded. Overall, nursing students reported less disgust and fear, but more sadness while watching the clips, compared to psychology students. The 2 groups did not differ in skin conductance activity when watching a video with no specific instructions. When instructed to suppress or reappraise their emotional reactions to the videos, however, the psychology students showed increases in skin conductance arousal, whereas the nursing students did not. The results are discussed within the context of research on strategies to regulate one's emotions in the workplace.     

Civic Engagement, Interpersonal Trust, and Television Use: An Individual-Level Assessment of Social Capital

The mechanisms underlying the formation and sustenance of social capital on the individual level were explored with a structural model composed of the endogenous variables of civic engagement and interpersonal trust. Using the 1995 DDB Needham life style study, analysis of the model permitted an examination of the strength and direction of the causal relationships driving the "virtuous circle" of participation and trust; the demographic, situational/contextual, orientational, and attitudinal factors that are exogenous to these latent variables; and the linkage between these components of social capital and viewing preferences for specific television genres. The results indicate that (1) the direction of the linkage between civic engagement and interpersonal trust is mainly from participating to trusting; and (2) television viewing plays a conditional role in the production of social capital that is dependent on the use of particular genres.     

Attention to Television: Alpha Power and Its Relationship to Image Motion and Emotional Content

A laboratory experiment investigated the impact of image motion and emotional content in brief television clips on attention. Using an electroencephalogram (EEG) as a measure of attention, cortical activity in 25 participants was measured while they viewed either still or moving emotion-provoking images. Spectral analysis of the EEG was done to gauge changes in alpha-wave (8-13 Hz) power because reductions in alpha power are thought to indicate greater attention. The analysis revealed that subjective reports of emotional arousal were directly related to cortical activation (i.e., reduced alpha power), and this was particularly true at the parietal recording site. The relationship between alpha power and ratings of valence was curvilinear; cortical activation was associated with both positive and negative images relative to neutral images. Alpha power was also reduced during the viewing of moving compared with still images, and this effect occurred independent of stimulus valence. The association of greater cortical activation with moving than with still images is consistent with previous research using autonomic measures and suggests that image motion modulates emotional responding-and sustains attention-primarily through increasing "gain" in the arousal dimension.     

Attention and Memory in Children with Brain Tumors

The Rey Auditory Verbal Learning Test was utilized to examine attention, learning, and memory abilities in 42 children with cerebellar (N?=?18) and third ventricle tumors (N?=?24). Children with cerebellar tumors exhibited significant auditory attentional impairments and displayed adequate encoding and retrieval across subsequent learning and memory trials. In contrast, children with third ventricle tumors exhibited average auditory attentional abilities, but they displayed mild encoding deficits across trials 2–5. Furthermore, the third ventricle group's compromised performance on the delayed recall trial and average performance on the delayed recognition trial is suggestive of underlying retrieval deficits.     

Attention After Pediatric Traumatic Brain Injury: A Multidimensional Assessment

Attentional disturbance is a common complaint after TBI in children and adolescents, however, few studies have assessed post-traumatic attentional functions. The attentional constructs proposed by Mirsky, Anthony, Duncan, Ahearn, and Kellam (1991) provided a multidimensional framework for prospective assessment of late attentional disturbance after mild-moderate (n = 34) and severe (n = 57) traumatic brain injury (TBI). Attention was evaluated from 5 to 8 years after TBI in children ages 0 to 15 years at the time of injury. Children with severe TBI performed more poorly than children with mild-moderate TBI on tests comprising the focus/execute and shift constructs. Younger children scored below older children irrespective of injury severity on the Digit Span subtest and interstimulus interval scores from an adaptive rate continuous performance test reflecting the encode and sustain constructs of Mirsky et al. (1991). Age × Severity interaction effects were found for speeded perceptual-motor tests; scores were reduced following mild-moderate and severe TBI in younger children and following severe TBI in older patients. Results are discussed in terms of the vulnerability of skills in a rapid stage of development to disruption by acquired brain injury.     

Predicting Selection and Activity in Television Genre Viewing

"Active" television viewing has meant (among other things) selective exposure to types of content, attention to that content, and several different kinds of other activities during viewing itself. This study argues that such meanings are differently predicted by three types of predictors (individuals' gratifications sought from different television genres, their expertise with these genres, and their need for cognition), and also vary by genre. Two different instrumental reasons for viewing (mood and content preference) both predicted selective viewing and thinking while viewing, but only content preference predicted attentive viewing. Casual reasons for viewing were related to less viewing and more channel surfing behavior. Need for cognition was unrelated to variation in genre viewing, but it was related in differing but sensible ways to attention to different genres.

These results support the utility of genre in differentiating processes in television viewing and further argue for making a number of distinctions in research: between genres, between gratifications, between gratifications and other predictors, and between selective viewing and during-viewing activities.     

Impairments of Attention Following Childhood Traumatic Brain Injury

Attentional deficits are commonly reported following traumatic brain injury (TBI) in adults, although the occurrence of such problems is less well documented in young children. This study aimed to investigate residual attentional abilities associated with TBI during childhood, by examining a number of aspects of attention including sustained, focussed, and divided attention, attentional shift, and response inhibition. Eighteen children with a history of TBI, aged between 8 and 14 years and 18 non-injured matched controls participated in the study. Results show that attentional skills may be differentially impaired after TBI, with children who have sustained moderate-to-severe TBI exhibiting significant deficits on the following attentional domains: sustain, focus, and response inhibition. These findings support the view that attentional impairments following pediatric TBI, while not global, may be more generalized than those reported for adult samples, perhaps reflecting the relative immaturity of attentional skills at the time of injury.     

Brain Activity and Cognitive Transition during Childhood: A Longitudinal Event-Related Brain Potential Study

This study examined the relation between brain activation and cognitive development using event-related brain potentials (ERPs) and a longitudinal design. Five-year-old girls performed a visual recognition (‘oddball’) task and an experimental analogue of the Piagetian conservation of liquid quantity task at three experimental sessions, with one year between consecutive sessions. The data revealed age-related changes in neurocognitive mechanisms common to both tasks. In comparing children before and after a Piagetian transition on a traditional clinical conservation test the data revealed a major shift in performance and ERPs to the experimental analogue of the liquid quantity task. These findings are consistent with a previously performed cross-sectional study and provide strong support for the hypothesis that cognitive transition is related to new neurocognitive mechanisms emerging during childhood. Possible implications of these findings for child neuropsychology are discussed.     

The Differential Impact of Religion on Political Activity and Community Engagement

Many religions have an ethos of community betterment that can spur their members to contribute to society in meaningful ways. Yet much of the literature on religion and politics tends to focus on how places of worship increase explicitly partisan activities like voting or donating to a political campaign. Does religion affect community engagement in the same ways that it does political participation? A unique research design executed in Little Rock, Arkansas, USA brings together religious data on individual beliefs and behaviors, clergy messaging, and congregation culture to examine religion’s effects on both political activity and community engagement. The results demonstrate that religion influences both types of behaviors, but not always in the same ways. For instance, it appears as though many congregations tend to develop cultures that encourage either community engagement or political activity, rather than both, with Black Protestant churches as an exception. Additionally, individuals that hold providential religious beliefs tend to have higher levels of community engagement but lower levels of political activity. These findings indicate that religion influences different types of participation differently.

     

Relating Kindergarten Attention to Subsequent Developmental Pathways of Classroom Engagement in Elementary School

We examine the relationship between children's kindergarten attention skills and developmental patterns of classroom engagement throughout elementary school in disadvantaged urban neighbourhoods. Kindergarten measures include teacher ratings of classroom behavior, direct assessments of number knowledge and receptive vocabulary, and parent-reported family characteristics. From grades 1 through 6, teachers also rated children's classroom engagement. Semi-parametric mixture modeling generated three distinct trajectories of classroom engagement (n?=?1369, 50% boys). Higher levels of kindergarten attention were proportionately associated with greater chances of belonging to better classroom engagement trajectories compared to the lowest classroom engagement trajectory. In fact, improvements in kindergarten attention reliably increased the likelihood of belonging to more productive classroom engagement trajectories throughout elementary school, above and beyond confounding child and family factors. Measuring the development of classroom productivity is pertinent because such dispositions represent precursors to mental health, task-orientation, and persistence in high school and workplace behavior in adulthood.     

Self-Controlled Practice to Achieve Neuro-Cognitive Engagement: Underlying Brain Processes to Enhance Cognitive-Motor Learning and Performance

Abstract

While self-controlled practice has been shown to be an effective practice methodology, the neuro-cognitive correlates of its effectiveness are unclear. We investigated whether learners participating in self-controlled practice exhibit increased neuro-cognitive engagement compared to externally controlled practice. Two groups (self-controlled and yoked) of 16 participants practiced and performed a golf putting task over 3 days. Working memory engagement, central executive activity, and cortical activation were assessed via electroencephalography as indicators of neuro-cognitive engagement. The self-controlled group exhibited more consistent working memory engagement, and greater central executive activity, compared to the yoked group during practice. Relationships were also observed between neuro-cognitive engagement during self-controlled practice and performance improvement, indicating that self-controlled practice uniquely benefitted from increased neuro-cognitive engagement.     

Medical Dramas and Viewer Perception of Health: Testing Cultivation Effects

By using a national representative sample (N = 11,555), the current study tested cultivation theory and aimed at understanding the relationship between medical drama watching and viewer perception and beliefs related to health. Findings suggest that heavy viewers of medical dramas tend to underestimate the gravity of chronic illnesses such as cancer and cardiovascular disease and undermine the importance of tackling these issues. Heavier viewers of medical dramas, compared to lighter viewers, also tend to take a more fatalistic perspective about cancer. Theoretical implications for cultivation theory and practical implications for health policy makers and drama producers are discussed.     

Attention Is Required to Coordinate Reaching and Postural Stability during Upper Limb Movements Generated While Standing

Abstract

In the present study we investigated how attention contributes to the interaction between reach planning and execution, and postural control. Reaching movements were generated while standing and were performed either in isolation or in conjunction with a secondary reaction time (RT) task. In addition, to better understand how online movement control is affected by this interaction, the reaching movements could be unexpectedly perturbed medial-laterally. Postural kinetic, arm kinematic and RT, and secondary RT measures were used to characterize the responses. Results indicate task performance worsened when both the reaching and secondary tasks were completed simultaneously. Our results imply the generation of reaching movements while standing requires attentional resources to properly coordinate the interaction between the reaching task and postural control.     

Repeated Measurement of the Components of Attention With Young Children Using the Attention Network Test: Stability,Isolability, Robustness,and Reliability

The current study examined the robustness, stability, reliability, and isolability of the attention network scores (alerting, orienting, and executive control) when young children experienced repeated administrations of the child version of the Attention Network Test (ANT; Rueda et al., 2004 Rueda , M. R. , Fan , J. , McCandliss , B. D. , Halparin , J. D. , Gruber , D. B. , Lercari , L. P. , … Posner , M. I. ( 2004 ). Development of attentional networks in childhood . Neuropsychologia , 42 , 1029 – 1040 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Ten test sessions of the ANT were administered to 12 young children. Participants were asked to indicate the direction of a target fish, flanked by distractors, presented either above or below the fixation cross following different types of visual cues. Network scores, reflecting alerting, orienting, and executive control, were calculated using orthogonal subtractions of performance in selected conditions. Only the alerting network scores remained highly significant across the 10 sessions. The executive network scores showed some practice effects. The reliability of the network scores remained poor regardless of the amount of data. Based on the results, use of the ANT is cautioned against in young children when repeated testing is required.     

Associations Between Infant Brain Activity and Recall Memory

Long‐term explicit memory is thought to involve a complex neural circuit including the medial temporal lobe, the medial diencephalon, the prefrontal cortex, and association cortices. When this memory system and associated neural circuitry develops is of great interest to developmental psychologists and developmental cognitive neuroscience researchers. In the present report, we provide evidence of a relation between behavioral and neurophysiological measures of long‐term explicit memory in 9‐month‐old infants. These measures provide converging evidence of the development of long‐term explicit memory at least by the end of the first year of life.
