Faster,slower or real time? Perceptual-cognitive skills training with variable video speeds

ObjectiveWe examined whether a short-term, off-field training intervention using different video speed manipulations (i.e., normal speed, 75%, and 125% of normal speed), enhances the offside decision-making performance of international level assistant referees. Moreover, we explored the optimal sequence of various video speed manipulations during training.DesignAll groups were exposed to a pre- and posttest. During acquisition, the assistant referees assessed 60 offside video simulations during three different training sessions. The order of the video speed conditions varied during the training intervention depending on participant group assignment: increasing speed group (n = 33; 75%–100%–125%); decreasing speed group (n = 33; 125%–100%–75%); and arbitrary speed group (n = 30; 100%–75%–125%).ResultsFirst, the decision-making accuracy was higher during the presentation of real time and faster video conditions when compared to the slower video condition. Second, only the decreasing speed group improved their offside decision-making performance from pre- to posttest.ConclusionsWe conclude that scheduling a decreasing video speed sequence throughout training is more beneficial to enhance learning than increasing or arbitrary speed conditions. Although it is too premature to replace existing training protocols that typically use constant speed videos, the present study offers evidence to suggest that training interventions for elite performers that decreasing the speed of exposure during the learning process may have some benefits over regular speed presentations.     

Implications of Technology for Social and Emotional Communication

Abstract

Communication technologies are transforming school psychology training and professional practices. To determine the effect of various communication technologies, this exploratory study contrasted three different communication modalities, including the receipt of messages via video, audio, and text. School psychology students were randomly assigned to those three conditions and asked to interpret the emotional intensity of a message conveyed in a case study concerning sexual and psychological abuse. Results showed different response patterns under the various conditions. Members of the group reading a text of the case study rated the emotional intensity as more extreme than did the members of the video and audio groups, both of whom had nonverbal affective information available to them. Practical implications for training and practice are discussed.     

Changing adolescent attitudes toward stuttering

Purpose

Live oral or recorded video presentations on stuttering were delivered to high school students in order to determine the extent to which their attitudes toward stuttering could be improved.

Methods

A classroom teacher administered the Public Opinion Survey of Human Attributes-Stuttering (POSHA-S) to two health classes before and after an oral live presentation by a person who stutters. She also gave the POSHA-S to two other similar classes before and after a True Life^®: I Stutter video presentation. The stuttering person in the oral condition was one of three people featured in the video. Also, following the video condition, students filled out the POSHA-S a third time after a short oral presentation by the same person who stutters.

Results

Measured attitudes improved overall on the POSHA-S and on selected items.

Conclusions

High school students hold similar attitudes toward stuttering and stutterers as adults, and these attitudes can be improved, at least temporarily, by a presentation on stuttering but more via a live presentation than a professionally prepared video.Educational objectives: (1) The reader will identify different ways to improve attitudes toward stuttering in high school students. (2) The reader will list advantages and disadvantages of live oral presentations and recorded video presentations as strategies to change attitudes toward stuttering. (3) The reader will identify characteristics of a speaker that can assist in attitude changes of high school students.     

Comparison of prompting procedures to teach internet skills to older adults

The Internet and information and communications technologies (ICTs) have been found to produce meaningful social interactions and greater social support among older adults (White et al., 2002 ). Despite these benefits, the Internet and ICTs are not widely used among the older‐adult population (Cresci, Yarandi, & Morrell, 2010 ). The purpose of the current study was to compare the effectiveness and efficiency of video prompting and text‐based instructions on the acquisition of three tablet‐based tasks: emailing, video calling (FaceTime® application), and searching for a YouTube? video. Both video prompting and text‐based instructions were effective for all three participants, with text‐based instructions being slightly more efficient for one participant and video prompting being more efficient for two participants, suggesting that both prompting procedures can be used to teach older adults Internet and ICT skills.     

Avatar‐Mediated Networking: Increasing Social Presence and Interpersonal Trust in Net‐Based Collaborations

This study analyzes the influence of avatars on social presence, interpersonal trust, perceived communication quality, nonverbal behavior, and visual attention in Net‐based collaborations using a comparative approach. A real‐time communication window including a special avatar interface was integrated into a shared collaborative workspace. Communication modes under investigation were text chat, audio, audio–video, and avatar. Significant differences were found between text chat and all other communication modalities in perceived intimateness, co‐presence, and emotionally‐based trust. Microanalyses of nonverbal activity and visual attention point to similarities between video and avatar modes, both showing higher levels of exposure to the virtual other and visual attention, in particular in the initial phase of interaction as compared to text and audio.     

Mobile Persuasion: Can Screen Size and Presentation Mode Make a Difference to Trust?

Guided by the Modality, Agency, Interactivity, and Navigability (MAIN) model of technology effects and the heuristic–systematic model (HSM) of information processing, this study explicates underlying mechanisms by which variations in screen size (large vs. small) and presentation mode (video vs. text) contribute to user perceptions of media content on their smartphones. Results from a between‐subjects experiment (N = 120) indicate that large screen size and video mode promote heuristic processing while small screen size and text mode encourage systematic processing. Heuristic processing leads to greater affective and behavioral trust while systematic processing is associated with cognitive trust. Phantom model analysis reveals the effects of large screen size and video mode on purchase intentions are sequentially mediated by type of information processing and multidimensional trust.     

Diagrams increase the recall of nondepicted text when understanding is also increased

Multimedia presentations typically produce better memory and understanding than do single-medium presentations. Little research, however, has considered the effect of multimedia on memory for nonmultimedia information within a large multimedia presentation (e.g., nondepicted text in a large text with diagrams). To this end, the present two experiments compared memory for target text information that was either depicted in diagrams or not. Participants (n 5 180) studied either a text-only version of a text about lightning or a textwith-diagrams version in which half the target information was depicted in diagrams. Memory was tested with both free recall and cued recall questions. Overall, diagrams did not affect memory for the entire text; diagrams increased memory only for the information they depicted. Diagrams exerted a generalized effect on free recall only when diagrams increased the overall understanding of the text (i.e., when the participants studied the materials twice before the test).     

When auditory presentations should and should not be a component of multimedia instruction

Based on cognitive load theory, two experiments investigated the conditions under which audiovisual‐based instruction may be an effective or an ineffective instructional technique. Results from Experiment 1 indicated that visual with audio presentations were superior to equivalent visual‐only presentations. In this experiment, neither the auditory nor the visual material could be understood in isolation. Both sources of information were interrelated and were essential to render the material intelligible. In contrast, Experiment 2 demonstrated that a non‐essential explanatory text, presented aurally with similar written text contained in a diagram, hindered learning. This result was obtained because when compared to a diagram only format, the aural material was unnecessary and therefore created a redundancy effect. Differences between groups were stronger when information was high in complexity. It was concluded that the effectiveness of multimedia instruction depends very much on how and when auditory information is used. Copyright © 2003 John Wiley & Sons, Ltd.     

Procedural Multimedia Presentations: The Effects of Working Memory and Task Complexity on Instruction Time and Assembly Accuracy

Procedural text conveys information of a series of steps to be performed. This study examined the role of verbal and visuo‐spatial WM in comprehension and execution of assembly instructions, as a function of format (text, images, multimedia) and task complexity (three or five steps). One hundred and eight participants read and executed 27 instructions to assemble a LEGO^TM object, in single and dual task conditions. Study times and errors during assembly were measured. Participants processed faster pictorial and multimedia instructions than text instructions, and made fewer errors in the execution of multimedia instructions. Dual task affected more text or picture‐only, than multimedia presentation. A verbal secondary task caused more errors in text or picture‐only presentations, and spatial secondary task also caused interference in text‐only instructions. Overall, these results support the multimedia advantage, and the role of both verbal and visuo‐spatial WM, when understanding instructions. Copyright © 2016 John Wiley & Sons, Ltd.     

Multi-level mental representations of written,auditory, and audiovisual text in children and adults

We examined whether the comprehension of narrative texts differed between auditory, audiovisual, and written text presentations in a sample of 8- and 10-year-olds and adults. Based on multi-level theories of text comprehension that assume text comprehension to involve at least three levels of mental representation, we applied a sentence recognition task that enabled the separate assessment of the memory of the text surface, text base, and the situation model. Results indicate that 8-year-olds benefit from audiovisual and auditory text presentations in comparison with written text presentations in terms of their memory of situation model information. For 10-year-olds and adults, their text comprehension did not differ between audiovisual, auditory, and written text presentations. Additionally, the mode of text presentation had no effect on the memory of text surface and text base information.     

TEACHER EFFECTIVENESS RESEARCH IN READING INSTRUCTION: EARLY EFFORTS TO PRESENT FOCUS

A quantitative and qualitative investigation was conducted to determine the relative efficacy of textual and instructional manipulations on concept acquisition. One hundred four high‐school chemistry students were assigned randomly to one of four treatments ‐‐ a group that read the course textbook (nonrefutational text), a group that read refutational text (i.e., text which cited and refuted common misconceptions about the topic for study), a group that read nonrefutational text but experienced a prereading activation activity (designed to elicit cognitive dissonance) and a group that read refutational text following the same activation activity. Results of Analyses of Covariance revealed no significant differences between the groups on three measures designed to assess concept comprehension and learning. A purposive sample of eleven students was selected for a qualitative examination of their text‐processing strategies. Analyses of audio‐recorded interviews revealed insights into the process of conceptual change. An instructional model of the construct of prior knowledge is presented.     

Children's Memory for News: A Comparison of Three Presentation Media

A study was conducted to compare children's learning of news information from television versus from audio-only or printed text presentations of the same narrative content. Although previous research among adults has yielded contradictory findings, research with children has found that they consistently remember news better from television than from print. The experiment extended this work by comparing children's recall of news information from different presentation media and investigating whether the effectiveness of the different media is dependent on expectation of a memory test and the children's reading proficiency. A sample of 166 male and female 10- and 11-year-olds was presented with a sequence of news stories taken from a children's news program either in their original televised form, in soundtrack only, or in a print version. Half of the children were led to expect a memory test, and half were not. The results of the cued recall test indicated that children learned more from television news than from the print and audio versions, regardless of their reading proficiency. The advantage of television was found only for information that had been accompanied by semantically redundant pictures in the televised version, providing support for the dual-coding hypothesis     

Effects of Age on the Temporal Organization of Working Memory in Deaf Signers

ABSTRACT

Deaf native signers have a general working memory (WM) capacity similar to that of hearing non-signers but are less sensitive to the temporal order of stored items at retrieval. General WM capacity declines with age, but little is known of how cognitive aging affects WM function in deaf signers. We investigated WM function in elderly deaf signers (EDS) and an age-matched comparison group of hearing non-signers (EHN) using a paradigm designed to highlight differences in temporal and spatial processing of item and order information. EDS performed worse than EHN on both item and order recognition using a temporal style of presentation. Reanalysis together with earlier data showed that with the temporal style of presentation, order recognition performance for EDS was also lower than for young adult deaf signers. Older participants responded more slowly than younger participants. These findings suggest that apart from age-related slowing irrespective of sensory and language status, there is an age-related difference specific to deaf signers in the ability to retain order information in WM when temporal processing demands are high. This may be due to neural reorganisation arising from sign language use. Concurrent spatial information with the Mixed style of presentation resulted in enhanced order processing for all groups, suggesting that concurrent temporal and spatial cues may enhance learning for both deaf and hearing groups. These findings support and extend the WM model for Ease of Language Understanding.     

Are schemas sufficient to interpret the personalization effect? Only if long-term working memory backs up

IntroductionIn the field of education, results have shown that text personalization allows for a processing of textual information. Several researchers have explained this advantage using the concept of “schema” but have not taken into account the linguistic nature of the texts.ObjectiveIn this study, we tested the importance of texts in the personalization effect. To do so, four groups of participants were contrasted with regard to the type of material (lists vs. texts) and personalization (personalized vs. non-personalized).MethodPersonalization consisted of introducing, or not, biographical elements allowing the reader to have, or not, a very familiar material to read. Therefore, two personalized groups that read some verbal material (lists or texts) mentioning some familiar locations were compared to two non-personalized groups that read verbal material (lists or texts) featuring unfamiliar locations. For the four groups, each location was associated with two objects. After the presentation phase, participants had to recognize the objects.ResultsAs expected, the personalized group recognized the objects more rapidly than the other group. A second finding showed that when the locations were not inserted in the texts (i.e., in lists), the personalization effect disappeared.ConclusionResults suggest that an explanation just in terms of “schemas” is insufficient. We think that the long-term working memory theory (Ericsson & Kintsch, 1995) allows us to complete this explanation thanks to the concept of episodic text memory.

Text On Screen: Can Emotionally Incongruent Combinations of Media Frames and Messages Elicit Coactivation in the Motivational Systems

ABSTRACT

Social media is becoming one of the most common deployment methods for antidrug and risk message campaigns. This is largely due to the low cost and high distribution that social media affords. This article argues that the social media approach to antidrug messaging also results in greater attention to the message over time. This article reports results from a study that examined how the combination of a short gain-or-loss framed text message interacts with a subsequent pleasant or unpleasant antidrug video message to influence motivational activation and information processing. Based on previous work investigating how different emotional trajectories in public service announcements (PSAs) elicit different patterns of motivational activation and cognitive processing, it was predicted, and found, that emotionally incongruent combinations of the text frame and video content resulted in the coactivation of the motivational systems. Placing a gain frame before a video message affects the overall processing of the subsequent message such that even an unpleasant message is rated more positively and results in a pattern of resource availability more like what we see for pleasant messages. Motivational activation and the subsequent effects on cognitive and emotional reactions are discussed within the context of multi-modal anti-drug campaigns.
