False memory ≠ false memory: DRM errors are unrelated to the misinformation effect

The DRM method has proved to be a popular and powerful, if controversial, way to study 'false memories'. One reason for the controversy is that the extent to which the DRM effect generalises to other kinds of memory error has been neither satisfactorily established nor subject to much empirical attention. In the present paper we contribute data to this ongoing debate. One hundred and twenty participants took part in a standard misinformation effect experiment, in which they watched some CCTV footage, were exposed to misleading post-event information about events depicted in the footage, and then completed free recall and recognition tests. Participants also completed a DRM test as an ostensibly unrelated filler task. Despite obtaining robust misinformation and DRM effects, there were no correlations between a broad range of misinformation and DRM effect measures (mean r  = -.01). This was not due to reliability issues with our measures or a lack of power. Thus DRM 'false memories' and misinformation effect 'false memories' do not appear to be equivalent

Off-farm Income and Investments in Farm Assets: A Double Hurdle Approach

The farm household structure is a complex set of inter-relationships between and among a variety of internal and external factors involving consumption, investment, and income-earning activities. In this paper we use ARMS data to explore the contribution of off-farm income to the viability of the farm business. We focus on the link between off-farm income and farm investment and whether off-farm income drives on-farm investment. The results indicate the importance of farm characteristics such as type, size, and location on the probability of investment but lead us to reject the hypothesis that off farm income is driving farm investment. Further research will be needed to further unweave some of the complex relationships involved in the farm household structure.

The Calysto Scheme Project

Calysto Scheme is written in Scheme in Continuation-Passing Style, and converted through a series of correctness-preserving program transformations into Python. It has support for standard Scheme functionality, including call/cc, as well as syntactic extensions, a nondeterministic operator for automatic backtracking, and many extensions to allow Python interoperation. Because of its Python foundation, it can take advantage of modern Python libraries, including those for machine learning and other pedagogical contexts. Although Calysto Scheme was developed with educational purposes in mind, it has proven to be generally useful due to its simplicity and ease of installation. It has been integrated into the Jupyter Notebook ecosystem and used in the classroom to teach introductory Programming Languages with some interesting and unique twists.Comment: Presented at The 2023 Scheme and Functional Programming Workshop (arXiv:cs/0101200

Differential Response of Female Deer Mice to Short Photoperiod

Author Institution: Department of Biological Sciences, Kent State UniversityIndividual male deer mice (Perotnyscus maniculatus} respond to inhibitory (short) photoperiod with gonadal responses that range from azoospermia to normal spermatogenesis. We undertook the present study to determine if female deer mice exhibit similar variation in reproductive response to inhibitory daylength. Following 8 wk exposure to short days, reproductive tract weights of 25% of all individual females did not differ from those displayed by mice housed on stimulatory (long) photoperiod; reproductive tracts of all remaining short day mice weighed significantly less. Short photoperiod also significantly reduced body weight, albeit only in those mice with regressed reproductive tracts. These results demonstrate that female deer mice respond differentially to the inhibitory effects of short photoperiod. Taken together with previous results, the present findings indicate that populations of deer mice are composed of subsets of males and females that differ in reproductive response to short daylength

The Multiple Roles of Anticipation in Developmental Robotics

Anticipatory systems have been shown to be useful in discrete, symbolic systems. However, non­symbolic anticipatory systems are less well understood. In this paper, we explore the use of anticipation within the framework of connectionist networks to bootstrap from an innate behavior; to drive a reinforcement signal; and to provide feedback on the learnability of a task

Computational Notebooks for AI Education

Computational notebooks are documents that serve dual purposes: they serve as an archive format containing code, text, images and equations; but they can also be run like computer programs. This paper explores the use of these new computational notebooks to teach AI and introduces tools that we have developed — ICalico and Calysto — to facilitate that use. Not only do these new tools broaden the languages and contexts available to students exploring notebook-based AI computing, but they offer a new mode of teaching and learning for the AI classroom
