Why do parents use screen media with toddlers? The role of child temperament and parenting stress in early screen use

Considering child characteristics may be an important piece to understanding parental decision-making for children’s screen use. The current cross-sectional study examined the mediating role of maternal parenting stress in the relation of child temperament to young children’s screen use. Recognizing the multidimensional aspects of temperament, three mediated pathways for three temperament domains (i.e., negative affectivity, surgency, and effortful control) were tested. Mothers of toddlers, 18–36 months (N = 296), completed an online survey, reporting on child temperament, total parenting stress, and child screen use. The results showed that mother-child dynamics were related to toddlers’ screen use. Toddlers’ negative affectivity and effortful control were each associated with toddlers’ screen use through maternal parenting stress. Higher negative affectivity was associated with higher maternal parenting stress, which in turn, was related to greater screen use in toddlers. Toddlers’ lower effortful control was related to higher maternal parenting stress, which in turn, was associated with greater screen use. Toddlers’ surgency was not related to either maternal parenting stress or toddlers’ screen use. The findings from this study contribute to an understanding of media-related parenting in toddlerhood and may help with the development of strategies for supporting healthy media habits in families with young children.     

Androgyny on the TV screen? An analysis of sex-role portrayal

Characters in a random sample of dramatic television programs representative of family time and later viewing time in 1975 and equivalent time periods in 1976 were rated on sex-role portrayal, using traits from the Bem Sex-Role Inventory (BSRI). The family time concept, which eliminated violence and sex from programs shown between 7:00 and 9:00 p.m. during 1975, had a significant effect on sex-role portrayal. Male characters were portrayed in a more realistic, though still highly masculine, way than their counterparts in other time periods. Female characters were portrayed as somewhat more feminine during family time than during other viewing hours. A significant interaction effect among viewing time, type of program, and sex of character suggested that content considered acceptable for younger viewers emphasized the stereotypical female role.This research was reported in part at the meeting of the Western Psychological Association, Seattle, April 1977. The author expresses appreciation to all those individuals who assisted with the project by serving as judges and as critics, and to the anonymous reviewer who made many helpful suggestions.     

Do we perceive a flattened world on the monitor screen?

The current model of three-dimensional perception hypothesizes that the brain integrates the depth cues in a statistically optimal fashion through a weighted linear combination with weights proportional to the reliabilities obtained for each cue in isolation (Landy, Maloney, Johnston, & Young, 1995). Even though many investigations support such theoretical framework, some recent empirical findings are at odds with this view (e.g., Domini, Caudek, & Tassinari, 2006). Failures of linear cue integration have been attributed to cue-conflict and to unmodelled cues to flatness present in computer-generated displays. We describe two cue-combination experiments designed to test the integration of stereo and motion cues, in the presence of consistent or conflicting blur and accommodation information (i.e., when flatness cues are either absent, with physical stimuli, or present, with computer-generated displays). In both conditions, we replicated the results of Domini et al. (2006): The amount of perceived depth increased as more cues were available, also producing an over-estimation of depth in some conditions. These results can be explained by the Intrinsic Constraint model, but not by linear cue combination.     

The early ontogeny of infants’ imitation of on screen humans and robots

Traditionally, infants have learned how to interact with objects in their environment through direct observations of adults and peers. In recent decades these models have been available over different media, and this has introduced non-human agents to infants’ learning environments. Humanoid robots are increasingly portrayed as social agents in on screen, but the degree to which infants are capable of observational learning from screen-based robots is unknown. The current study thus investigated how well 1- to 3-year-olds (N = 230) could imitate on-screen robots relative to on-screen and live humans. Participants exhibited an imitation deficit for robots that varied with age. Furthermore, the well-known video deficit did not replicate as expected, and was weak and transient relative to past research. Together, the findings documented here suggest that infants are learning from media in ways that differ from past generations, but that this new learning is nuanced when novel technologies are involved.     

Preparation of forefinger’s sequence on keyboard orients ocular fixations on computer screen

This study examined the links between attention, hand movements and eye movements when performed in different spatial areas. Participants performed a visual search task on a computer screen while preparing to press two keyboard keys sequentially with their index. Results showed that the planning of the manual sequence influenced the latency of the first saccade and the placement of the first fixation. In particular, even if the first fixation placement was influenced by the combination of both components of the prepared manual sequence in some trials, it was affected principally by the first component of the prepared manual sequence. Moreover, the probability that the first fixation placement did reflect a combination of both components of the manual sequence was correlated with the speed of the second component. This finding suggests that the preparation of the second component of the sequence influence simultaneous oculomotor behavior when motor control of the manual sequence relied on proactive motor planning. These results are discussed taking into account the current debate on the eye/hand coordination research.     

What is the prevalence of adult ADHD? Results of a population screen of 966 adults

To provide a better estimate of the prevalence of ADHD in adulthood, the authors complete a telephone survey of 966 randomly selected adults. They compute two diagnoses from the survey data. Participants meeting Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for both childhood and adulthood are defined as narrow ADHD. Broad ADHD adds to that definition those meeting subthreshold criteria. Cronbach's alpha is .90 for the 18 DSM-IV symptoms in childhood and .88 when rated for current symptoms in adulthood. No one item unduly influences the reliability of the total score. The authors find similar results in separate analyses of hyperactive-impulsive and inattentive symptoms. They estimate prevalences of 2.9% for Narrow ADHD and 16.4% for Broad ADHD. Having ADHD is associated with lower levels of education and employment status. These findings suggest that adult ADHD is a common disorder associated with impaired functioning.     

The importance of visual angle in word recognition: A “shrinking screen” modification for visual displays

The visual angle subtended by alphabetic stimuli seems to be given little regard in a large proportion of reading research. Existing empirical evidence suggests that this disregard may be unwise. We describe a modification to video monitors and oscilloscopes that allows the screen size of stimuli to be varied and permits words to be displayed at appropriate visual angles with accuracy and comparative ease. Other advantages of these modifications are also discussed.     

Usability evaluation with screen reader users: a video presentation of the PCTA’s experimental setting and rules

In the study entitled “Web usability evaluation with screen reader users: Implementation of the Partial Concurrent Thinking Aloud technique” (Federici et al. 2010), we have proposed a modified protocol of usability evaluation technique for blind users, which integrates the features of the concurrent and the retrospective techniques. This new technique, called partial concurrent thinking aloud (PCTA), while respecting the properties of classic verbal protocols, overcomes the structural interference and the limits of concurrent and retrospective protocols when used with screen reader users. In order to facilitate understanding and acquisition of the PCTA’s technique for practitioners and researchers, we have video recorded three different verbal protocols by visualizing five experimental sections. In the first two videos, we have compared a concurrent with a retrospective’s verbal protocol of a sighted user, showing the difference of the verbalizations provided by the user in these two conditions. The third video shows the structural interference of the screen reader, during a blind user concurrent thinking aloud. In the last two videos, we show the difference of a blind user behaviour when PCTA or retrospective protocol is adopted. The videos clearly visualize the advantage of the PCTA use in respect of the two other protocols. In conclusion, the visualization of the PCTA technique confirms that this new verbal protocol promotes and guarantees a more user-driven usability assessment with disabled people, by better involving screen reader users, overcoming the structural interference and the limits of the concurrent and retrospective protocols.     

Using a touch screen paradigm to assess the development of mental rotation between 3½ and 5½ years of age

Mental rotation is an important spatial skill. However, there is controversy concerning its early development and susceptibility to intervention. In the present study, we assessed individual differences in the mental rotation abilities of children between 3½ and 5½ years of age, using a touch screen paradigm to simplify task demands. A figure or its mirror image was presented in 8 different orientations, and children indicated in which of two holes the figure would fit by touching one of the holes on the screen. Task instructions were varied in three conditions, giving the children the opportunity to gather manual or observational experience with rotations of different stimuli, or giving no additional experience. Children’s error rates and response times increased linearly with increasing angular disparity between the figure and the hole by the age of 5 years, but 4-year-olds were found to respond at chance for all angular disparities, despite the use of a touch screen paradigm. Both manual and observational experience increased the response accuracy of 5-year-olds, especially for children already performing well. However, there was no effect on 4-year-olds. Results point to an emerging readiness to use mental rotation and profit from observational and manual experience at age 5.     

Languages on the screen: Is film comprehension related to the viewers’ fluency level and to the language in the subtitles?

This research aimed at studying the role of subtitling in film comprehension. It focused on the languages in which the subtitles are written and on the participants' fluency levels in the languages presented in the film. In a preliminary part of the study, the most salient visual and dialogue elements of a short sequence of an English film were extracted by the means of a free recall task after showing two versions of the film (first a silent, then a dubbed-into-French version) to native French speakers. This visual and dialogue information was used in the setting of a questionnaire concerning the understanding of the film presented in the main part of the study, in which other French native speakers with beginner, intermediate, or advanced fluency levels in English were shown one of three versions of the film used in the preliminary part. Respectively, these versions had no subtitles or they included either English or French subtitles. The results indicate a global interaction between all three factors in this study: For the beginners, visual processing dropped from the version without subtitles to that with English subtitles, and even more so if French subtitles were provided, whereas the effect of film version on dialogue comprehension was the reverse. The advanced participants achieved higher comprehension for both types of information with the version without subtitles, and dialogue information processing was always better than visual information processing. The intermediate group similarly processed dialogues in a better way than visual information, but was not affected by film version. These results imply that, depending on the viewers' fluency levels, the language of subtitles can have different effects on movie information processing.     

A longitudinal examination of daily amounts of screen time and technoference in infants aged 2–11 months and associations with maternal sociodemographic factors

This study aimed to examine longitudinal developmental patterns in the daily amounts of screen time and technoference in infants aged 2, 4, 7, and 11 months and to examine associations with maternal sociodemographic factors across all age groups.The results showed that the amount of screen time varied between 6 and 17 min a day, while interruptions in mother-infant interactions due to maternal use of digital technology occurred between 5 and 6 times a day. There was a significant increase in infant screen time from 2 to 4 months, from 4–7 months, and from 7–11 months, and in technoference from 2 to 4 months and from 4–7 months. Maternal age and household income were not associated with infant screen time, but maternal educational level was negatively associated with infant screen time throughout the first year. No associations were found between technoference and maternal age, maternal educational level, or household income.Future research focusing on infant screen time and technoference should aim at including samples that reflect the general population, include measures of screen time and technoference that do not rely on parental report, and include measures of the effects of early infant screen time and technoference on later development.
