For my own research, I am considering where to submit papers about the perception of sign language and other gestures. I previously submitted a paper to the journal Gesture, but other journals might be good as well or even better. Let us consider a few candidates: Gesture, SLS, TAP, JEP:HPP, LCP, SLL, JML, and more

Gesture is a multidisciplinary journal about all sorts of gestures, including sign language. There are often long papers, sometimes about experimental work, and sometimes theoretical. It is supported by the ISGS. Main editors are Adam Kendon and Cornelia Muller.

Gesture publishes articles reporting original research, as well as survey and review articles, on all aspects of gesture. The journal aims to stimulate and facilitate scholarly communication between the different disciplines within which work on gesture is conducted. For this reason papers written in the spirit of cooperation between disciplines are especially encouraged. 

Sign Language Studies seems a general forum for a large variety of sign language studies, with a special place for research regarding Deaf culture and communities (see also the Gallaudet University home of editor David F. Armstrong). It seems like the editorial board of SLS has some overlap with the board of Gesture. They both list for example Adam Kendon, David McNeill and Sherman Wilcox. :

Sign Language Studies publishes a wide range of original scholarly articles and essays relevant to signed languages and signing communities. The journal provides a forum for the dissemination of important ideas and opinions concerning these languages and the communities who use them. Topics of interest include linguistics, anthropology, semiotics, Deaf culture, and Deaf history and literature. While the journal is especially interested in work concerning Deaf communities, signed languages used by hearing people are also of interest. 

The ACM Transactions on Applied Perception (ACM TAP) provides a platform for those who try to bridge the gap between human perception and computer vision work (Editors. Erik Reinhard, Heinrich H. Bülthoff)

TAP: A current trend in the field of computer science is the assimilation of results from other disciplines. In particular, there is a move towards the application of breakthroughs from the field of experimental psychology. The purpose of ACM Transactions on Applied Perception is to further the development of inter-disciplinary research that crosses the boundaries between perception and computer science disciplines such as graphics, vision, acoustics and haptics. The scope of this journal includes applications and algorithms in any of these fields that incorporate elements of perception. 

Language and Cognitive Processes has a history of publishing work on both sign language and gesture. The editorial board includes people with expertise in gestures (e.g. Levelt) and sign language (e.g. Grosjean).

Language and Cognitive Processes provides an international forum for the publication of theoretical and experimental research into the mental processes and representations involved in language use. The psychological study of language has attracted increasing research interest over the past three decades, and Language and Cognitive Processes provides a common focus for this enterprise. The journal is also interested in fostering the relationship between cognitive theoretical accounts of language and its neural bases, and for this reason will consider research on the cognitive neuroscience of language which is rooted in cognitive theory. 

The Journal of Experimental Psychology: Human Perception and Performance has previously published studies on sign language, and it might be a good option:

The Journal of Experimental Psychology: Human Perception and Performance publishes studies on perception, control of action, perceptual aspects of language processing, and related cognitive processes. All sensory modalities and motor systems are within its purview (more detailed

I briefly considered Sign Language & Linguistics, but they seem to recruit sign language research for general linguistic topics (which the title already suggested, I must confess). That is not necessarily a bad thing, it is just not my cup of tea.

Sign Language & Linguistics aims to increase our understanding of language by providing an academic forum for researchers to discuss sign languages in the larger context of natural language, crosslinguistically and crossmodally. SLL presents studies that apply existing theoretical insights to sign language in order to further our understanding of SL; it investigates and expands our knowledge of grammar based on the study of SL and it specifically addresses the effect of modality (signed vs. spoken) on the structure of grammar. 

The Journal of Memory and Language has published papers on gestures (and speech), I am not sure of sign language research (ed. K. Bock):

Articles in the Journal of Memory and Language contribute to the formulation of scientific issues and theories in the areas of memory, language comprehension and production, and cognitive processes. Special emphasis is given to research articles that provide new theoretical insights based on a carefully laid empirical foundation. 

The American Annals of the Deaf covers a range of topics (mostly life sciences but some technology applications) concerning being Deaf and sign language. (ed. D. Moores, board).

[it] is a professional journal dedicated to quality in education and related services for deaf or hard of hearing children and adults. First published in 1847, the Annals is the oldest and most widely read English-language journal dealing with deafness and the education of deaf persons. The Annals is the official organ of the Council of American Instructors of the Deaf (CAID) and of the Conference of Educational Administrators of Schools and Programs for the Deaf (CEASD) and is directed and administered by a Joint Annals Administrative Committee made up of members of the executive committees of both of these organizations. 

The Journal of Deaf Studies and Deaf Education consists mainly of research on Deaf people. There is nothing on technology but perceptual studies are not excluded (Ed. M. Marschark, board)

[it] is a peer-reviewed scholarly journal integrating and coordinating basic and applied research relating to individuals who are deaf, including cultural, developmental, linguistic, and educational topics. 

Slightly farther away on the horizon, but possible for specific subjects (all have a history of publishing work on gesture or sign language):

Which other journals should I consider? (Honestly, if you have suggestions, please leave a comment). Update 13 feb ’07: Impact factors may be important as well, though it seems a bit hard to find them. Update 11 sep ’07: The TU Delft, where I work, keeps a the following administration on publications:

De TU Delft hanteert een peerlijst, waarop wetenschappelijke tijdschriften staan genoemd, die niet in de CWTS-lijst voorkomen. Publicaties in zo’n tijdschrift van de peerlijst worden met 4 outputpunten beloond door de BTA-commissie (mits minimaal vier pagina’s). Publicaties in een tijdschrift dat noch in de CWTS-lijst, noch in de peerlijst staat worden met slechts 1 punt beloond, of ze nu wetenschappelijk zijn of niet. 

I checked the CWTS-lijst and the Peerlijst for the journals listed above: Gesture, SLS, TAP, LCP, JEP:HPP, SLL, JML, AAOTD, JDSDL The CWTS-list contains the following journals of interest: Language and Cognitive Processes Journal of Experimental Psychology-Human Perception and Performance Journal of Memory and Language Journal of Deaf Studies and Deaf Education American Annals of The Deaf Human Movement Science Mind & Language, Language & Communication, Journal of Child Language, Perception, Cognitive Science, Applied Cognitive Psychology, Cognitive Linguistics, European Journal of Cognitive Psychology, Trends In Cognitive Sciences, Research On Language and Social Interaction Computer Speech and Language Journal of Visual Languages and Computing Language Learning & Technology Quarterly Journal of Experimental Psychology Section A-Human Experimental Psychology The ‘peerlijst’ contains only one items of potential interest: Visible language. Perhaps I can suggest that those journals which are not on the CWTS-list can be put on the peerlijst. These are (in order of relevance for my own research): Gesture, Sign Language Studies, ACM Transactions on Applied Perception, Sign Language Linguistics, Semiotica, Sign Systems Studies, Perception and Motor Skills, International Review of Applied Linguistics in Language Teaching, International Journal of Research and Practice in Interpreting.
