Zusammenfassung: Die Effektivität des Lernens aus Lösungsbeispielen im Vergleich zum Lernen durch Problemlösen wird derzeit mit der Cognitive Load-Theorie erklärt: Beim Lernen aus Lösungsbeispielen wird das Arbeitsgedächtnis weniger belastet, daher bleibt mehr Raum für Lern- und Verstehensprozesse. Um diese These direkt experimentell zu überprüfen, wurde das dual task-Paradigma eingesetzt. 80 Studierende der Geistes- und Sozialwissenschaften wurden auf die Zellen eines 2 × 2-faktoriellen Designs (Faktor 1: Lernen aus Lösungsbeispielen vs. Lernen durch Problemlösen; Faktor 2: mit vs. ohne Zweitaufgabe) verteilt. Der Lernstoff war Wahrscheinlichkeitsrechnung. Der Lernerfolg wurde mit einem Nachtest erfasst. Das Befundmuster hinsichtlich des Lernerfolgs und der Reaktionszeiten auf eine Zweitaufgabe in den vier experimentellen Gruppen stimmte mit den aus der Cognitive-Load-Theorie abgeleiteten Hypothesen überein.

Abstract. In two pilot experiments, a new approach for the direct assessment of cognitive load during multimedia learning was tested that uses dual-task methodology. Using this approach, we obtained the same pattern of cognitive load as predicted by cognitive load theory when applied to multimedia learning: The audiovisual presentation of text-based and picture-based learning materials induced less cognitive load than the visual-only presentation of the same material. The findings confirm the utility of dual-task methodology as a promising approach for the assessment of cognitive load induced by complex multimedia learning systems.

Guidelines for designing usable interfaces recommend reducing short term memory load. Cognitive load, that is, working memory demands during problem solving, reasoning, or thinking, may affect users' general satisfaction and performance when completing complex tasks. Whereas in design guidelines numerous ways of reducing cognitive load in interactive systems are described, not many attempts have been made to measure cognitive load in Web applications, and few techniques exist. In this study participants' cognitive load was measured while they were engaged in searching for several products in four different online book stores. NASA-TLX and dual-task methodology were used to measure subjective and objective mental workload. The dual-task methodology involved searching for books as the primary task and a visual monitoring task as the secondary task. NASA-TLX scores differed significantly among the shops. Secondary task reaction times showed no significant differences between the four shops. Strong correlations between NASA-TLX, primary task completion time, and general satisfaction suggest that NASA-TLX can be used as a valuable additional measure of efficiency. Furthermore, strong correlations were found between browse/search preference and NASA-TLX as well as between search/browse preference and user satisfaction. Thus we suggest browse/search preference as a promising heuristic assessment method of cognitive load.

Context Deficits in both balance and oculomotor function, including impairments in saccadic eye movements, are observed in approximately 30% of patients postconcussion. Whereas balance and saccadic eye movements are routinely assessed separately, growing evidence suggests that they should be assessed concurrently. Objective To compare balance measures and saccades between adolescents 1 to 3 months postconcussion and healthy uninjured adolescents. Design Case-control study. Setting Concussion clinic and 2 private schools. Patients or Other Participants Twenty-five adolescents (10 boys, 15 girls; median [interquartile range (IQR)] age = 14 years [11.5–16 years]) between 1 and 3 months postconcussion (median [IQR] time since injury = 39.5 days [30–56.75 days]) and 33 uninjured adolescents (18 boys, 15 girls; median [IQR] age = 13 years [11.5–14 years]). Main Outcome Measure(s) The center-of-pressure 95% ellipse area and medial-lateral and anterior-posterior velocity and the number of saccades in the dual-task balance conditions including a high cognitive load (cognitive condition), a low cognitive load and a gaze-shifting component (visual condition) or both a high cognitive load and a gaze-shifting component (combined condition). Results Concussion-group participants swayed over larger center-of-pressure ellipse areas in the visual (P = .02; effect size = 0.73) and combined (P = .005; effect size = 0.86) conditions but not in the cognitive condition (P = .07; effect size = 0.50). No group differences were identified for anterior-posterior (F1,56 = 2.57, P = .12) or medial-lateral (F1,56 = 0.157, P = .69) velocity. Concussion-group participants also did not perform more saccades than the control-group participants (F1,56 = 2.04, P = .16). Conclusions Performing dual-task balance conditions for which the secondary task involved a gaze-shifting component or both a gaze-shifting component and a high cognitive load resulted in greater sway amplitude in adolescents with concussion. However, these larger amounts of postural sway were not associated with increased saccadic eye movements.
