Based on the knowledge generation model for visual analytics including uncertainty propagation and human trust building (Sacha et al. 2016), the cognitive theory of multimedia learning (Mayer, 2014), the multimedia principle (Butcher, 2014), and previous studies on the effects of different uncertainty visualization styles, an integrated…

Since the complex and transient information in instructional animations requires more cognitive resources, the segmenting principle has been proposed to reduce cognitive overload by providing smaller chunks with pauses between segments. This study examined the effects of different types of activities during pauses in a segmented animation. Four…

A spatial-arrangement or word-arrangement mnemonic experiment was conducted in which college students studied six lists of 12 words each under conditions of word pattern and/or mnemonic instruction. Both the link mnemonic and distinctive word arrangements enhanced recall during acquisition, but only word-arrangement had a significant effect on…

One hundred undergraduates learned lists of high- or low-imagery nouns in one column (ungrouped) or in three columns (grouped). Grouped-list recall was significantly greater than ungrouped on the third and fourth trials. Spatial grouping seems to provide important cues which are independent of the words learned or imagery level. (Author/CM)

In order to test the hypothesis that bizarre imagery can be an effective mnemonic aid with delayed testing, a context of mixed materials, and an adequate stimulus presentation pace, a study examined 40 undergraduates who were randomly presented with three paired-associate lists (normal, bizarre, and mixed). Within each list the sentences consisted…

The nature of the target designation process--which involves forming interassociated mental structures to allow retrieval of individual items of information--was studied. It was shown that visual imagery instructions improved target identification as well as word recognition but did not appear to affect the representational format. (Author/MH)

Recent findings have shown that bizarre imagery can be an effective mnemonic aid when lengthy retention intervals are employed, and when the surrounding context contains more normal elements. Testing the hypothesis that an interaction exists between context and time of testing with bizarre images, a study paired 40 male and female undergraduates,…

This report describes a study of how maps are learned. Subjects (undergraduate students at the University of California) studied a simple map under various conditions and then answered questions about the map and drew the map from memory. It was found that local relations are learned before large-scale relations, that different types of map…

The purpose of these studies was to provide evidence to support either the dual-coding hypothesis or the single-system hypothesis of human memory. In one experiment, college subjects were shown a mixed series of words and pictures either while simultaneously engaged in shadowing (repeating aloud) a prose passage presented via earphones or while…

Studies support the hypothesis that images aroused by discreet verbal stimuli can be integrated into complex images with the result that: (a) storage capacity requirements are reduced, and (b) recall of one component of the image leads to effective redintegration of the rest. (JB)

The effects of rate repetition, self-generated visualization, and supplied visuals on the memorization of concrete noun-word pairs were investigated using 27 gifted children in grades four to six. The hypothesis that self-generated imagery techniques would be superior to supplied visuals was not supported. (Author/PN)

Experiments were performed to determine the contribution of imagery and semantic factors to the hypermnesia effect (increases in retention over successive recall attempts). Results showed that hypermnesia accompanies meaningful processing regardless of whether verbal or imagery encoding is emphasized. Semantic elaboration increases reminiscence…

Instructional designers need to understand the internal processes of learning, identify learners' cognitive difficulties with those processes, and create strategies to help learners overcome those difficulties. Generative learning theory, one conception of human learning about cognitive functioning and process, emphasizes that meaningful learning…

Kindergarten and first-grade children listened to a narrative passage under one of five experimental conditions. Prelearning imagery instructions did not facilitate subsequent recall of story information. Similarly intermittently provided pictures did not produce recall gains for unpictured story information, but had a positive effect on recall of…
