****************************************************************************

Diagrams 2018 is the tenth conference in the biennial series that
started in 2000, which provides a united forum for all areas concerned
with the study of diagrams.

For 2018, we will have a special track devoted to psychological issues
pertaining to diagrams. Special theme topics include any research on
the psychology of diagrams, such as:

- cognitive aspects of diagrams and diagrammatic thinking, including:
+ reasoning with diagrams,
+ comprehension of diagrams,
+ mental imagery and mental animation,
- diagrams and wayfinding,
- diagrams as pedagogical tools,
- human perception and the design of diagrams,
- reasoning with diagrams from a psychological perspective,
- sociocultural interpretations of diagrams,
- spatial structure of diagrams,
- students' use or misuse of diagrams.

If the main research contribution of your submission is considered to
be on the psychology of diagrams you are strongly encouraged to submit
to this track with its dedicated Program Committee.

****************************************************************************
Submission Categories

Diagrams 2018 will include presentations of refereed Papers, Abstracts,
and Posters, alongside tutorials, workshop sessions, and a graduate
symposium.

We invite submissions for peer review that focus on any aspect of
diagrams research, as follows:

- Long Papers (16 pages)
- Abstracts (3 pages)
- Short Papers (8 pages)
- Posters (4 pages - this is both a maximum and minimum requirement)

All submissions should include diagrams where appropriate. Submission
of Long Papers, Abstracts, Short Papers, and Posters should be made to
either the main conference track, or one of the special session tracks,
on the philosophy of diagrams and the psychology of diagrams.

Long Papers and Short Papers should report on original research
contributions.

Submissions to the Abstracts category should report on significant
research contributions, which may have been published elsewhere (such
submissions must clearly cite prior work) or are intended to be
published elsewhere. The contribution should be of a similar level to
that expected of a Long Paper. Submissions to the Abstracts category
will not be included as an archival contribution in the proceedings.
Accepted Abstract submissions will be offered the same presentation
time in the program as Long papers. High quality Abstract submissions
that nonetheless fall short of the standard required for full
acceptance may be accepted for a short presentation. The Abstracts
submission category is not intended for work-in-progress; the Poster
submission category should be used for work-in-progress.

Posters may report on original, yet early stage, research or on
previously published research that is of interest to the Diagrams
community (such submissions must clearly cite prior work).

****************************************************************************
Proceedings

The Proceedings will be published by Springer in their Lecture Notes
in Computer Science series. The Long papers, Short papers, and Posters
will be indexed by Springer, whilst the Abstracts will not.

****************************************************************************
Formatting Guidelines

All submissions must follow Springer's LNCS formatting guidelines:

Title: Motion capture depends upon the common fate factor among elements.

Journal(書誌情報）: Perception

doi: 10.1177/0301006617720123

論文URL: http://journals.sagepub.com/doi/10.1177/0301006617720123

Abstract:
When observers move the head backwards and forwards while fixating on the center of the concentric circles that consist of oblique lines, they see illusory rotation of those circles. If several dots are superimposed on the proximity to the inner concentric circles, observers see the illusory rotation not only for the circles but also for the superimposed dots. This illusory rotation of the dots is based on motion capture. In this study, in order to understand the basis of the motion capture, we examined how motion signal with different directions (rotation, expansion/contraction, and horizontal translation) in terms of motion on a display, as well as illusory motion signal from the oblique components, affects the motion capture. If the stimulus presented rotation with expansion/contraction, or rotation with horizontal translation for the entire stimulus, then observers tended to perceive motion capture for the superimposed dots. However, if the stimulus presented only rotation of the circles, then observers tended to perceive induced motion for the superimposed dots. These results suggest that the existences of the common fate factor for the entire stimulus determine the means of allocating and integrating the motion signal in each element in the stimulus to generate motion capture.

日本語によるコメント（オプション，200-300字で）：
運動捕捉とは，静止した刺激が，運動する刺激と同じ方向に動いているように見えるという錯視現象である．運動捕捉が生じると，運動刺激とは逆に動いて見える誘導運動とは反対の方向の動きが見えることになる． 今回の論文では，Pinna錯視を用いた実験により，刺激全体にかかわる共通の運動的特性，つまりは「共通運命」があれば運動捕捉が生じるのに対し，そうした共通の運動的特性がなければ誘導運動が生じるのかが決められることが示された．これらの結果は，視覚系が，刺激間の共通運命特性に従って視野内の要素への運動情報の割り当て様式を決めることを示唆している．

Title: Neural mechanisms underlying the reward-related enhancement of motivation when remembering episodic memories with high difficulty

Journal(書誌情報）: Human Brain Mapping, 38(7), 3428-3443, 2017

doi: 10.1002/hbm.23599

論文URL: http://onlinelibrary.wiley.com/doi/10.1002/hbm.23599/full

Abstract:
The motivation to receive rewards enhances episodic memories, and the motivation is modulated by task difficulty. In episodic retrieval, however, functional neuroimaging evidence regarding the motivation that mediates interactions between reward and task difficulty is scarce. The present fMRI study investigated this issue. During encoding performed without fMRI, participants encoded Japanese words using either deep or shallow strategies, which led to variation in difficulty level during subsequent retrieval. During retrieval with fMRI, participants recognized the target words in either high or low monetary reward conditions. In the behavioral results, a reward-related enhancement of memory was found only when the memory retrieval was difficult, and the rewarding effect on subjective motivation was greater in the retrieval of memories with high difficulty than those with low difficulty. The fMRI data showed that reward-related increases in the activation of the substantia nigra/ventral tegmental area (SN/VTA), medial temporal lobe (MTL), dorsomedial prefrontal cortex (dmPFC), and dorsolateral prefrontal cortex (dlPFC) were greater during the retrieval of memories with high difficulty than those with low difficulty. Furthermore, reward-related enhancement of functional connectivity between the SN/VTA and MTL and between the SN/VTA and dmPFC during the retrieval of memories with high difficulty was significantly correlated with reward-related increases of retrieval accuracy and subjective motivation. The reward-related enhancement of episodic retrieval and retrieval-related motivation could be most effective when the level of retrieval difficulty is optimized. Such reward-related enhancement of memory and motivation could be modulated by a network including the reward-related SN/VTA, motivation-related dmPFC, and memory-related MTL.

Title: Remembering my friends: Medial prefrontal and hippocampal contributions to the self-reference effect on face memories in a social context

Journal(書誌情報）: Human Brain Mapping, 38(8), 4256-4269, 2017

doi: 10.1002/hbm.23662

論文URL: http://onlinelibrary.wiley.com/doi/10.1002/hbm.23662/full

Abstract:
Memories associated with the self are remembered more accurately than those associated with others. The memory enhancement related to the self is known as the self-reference effect (SRE). However, little is known regarding the neural mechanisms underlying the SRE in a social context modulated by social relationships. In the present fMRI study, we investigated encoding-related activation of face memories encoded with the self-referential process in a social context that was manipulated by imagining a person-to-person relationship. Healthy young adults participated in the present study. During encoding, participants encoded unfamiliar target faces by imagining a future friendship with themselves (Self), their friends (Friend), or strangers (Other). During retrieval, participants were presented with target and distracter faces one by one, and they judged whether each face had been previously learned. In the behavioral results, target faces encoded in the Self condition were remembered more accurately than those encoded in the Other condition. fMRI results demonstrated that encoding-related activation in the medial prefrontal cortex (mPFC) was significantly greater in the Self condition than in the Friend or Other conditions. In addition, the generalized psycho-physiological interaction (gPPI) analysis showed that functional connectivity between activation in the hippocampus and the cortical midline structures (CMSs), including the mPFC and precuneus, was significant in the Self but not in the Other condition. These findings suggest that the SRE in a social context could be involved in the interaction between the CMS regions, which are related to the self-referential process, and the hippocampus related to the memory process.
