Data archiving in animal experimentation: Merits,challenges, and a case study

Electronic data archives may supplement the traditional peer-reviewed journal article. The merits of data archiving include public service, a more complete research project, overcoming barriers to limited-access research resources, and increasing the impact of a scientific project. A case study of chimpanzee timing performance in space is derived from the NASA Life Sciences Data Archive (http://lsda.jsc. nasa.gov). An analysis of the archived data suggests that the scalar property (a form of Weber’s law) applies to timed performance of a chimpanzee in orbit of the earth. Challenges associated with data archives are discussed. Although significant challenges are associated with archiving electronic data, these difficulties are outweighed by its merits.     

Data archiving for animal cognition research: report of an NIMH workshop

In July 2001, the National Institute of Mental Health sponsored a workshop titled "Data Archiving for Animal Cognition Research." Participants included scientists as well as experts in archiving, publishing, policy, and law. As is described in this report, the workshop resulted in a set of conclusions and recommendations concerning (A) the impact of data archiving on research, (B) how to incorporate data archiving into research practice, (C) contents of data archives, (D) technical and archival standards, and (E) organizational, financing, and policy issues. The animal cognition research community is encouraged to begin now to establish archives, deposit data and related materials, and make use of archived materials in new scientific projects.     

The archive and psychoanalysis: Memories and histories toward futures

Abstract

The archive and psychoanalysis are reconnected in a new framework. The archaeological metaphor of psychoanalysis, the traditional view of archives as storehouses of historical items, and the notion of memory as storage are revised according to the conceptions of fluid and dynamic archival and memory systems. A combination of psychoanalytic models and cognitive memory research is proposed to form developmental archival theory that will take into account the changing contexts of memory, meaning-making, negotiation of interpretation, and knowledge regulation. The three phases of registration (archivalization, archivization, and archiving) are seen in the dynamics of unconsciousness–consciousness, and in relation to the archivists’ and researchers’ transferences to their records as self-objects, transitional objects or evocative objects. Becoming conscious of archives is a continuous journeying through the multiple registrations and narrativizations of archives in the interaction between non-declarative and declarative memory. The archive and psychoanalysis touch upon processes that are suggested to concern metamemory and metareflection (the interplay between meta-emotion and metacognition). The futures of archives and psychoanalysis call for context-sensitive remembering and being attentive to the co-constructive translations of personal and social memory. Opening archives and psychoanalysis toward the unprecedented, without closing histories and memories, is the interminable task of encountering the “missing moment.”     

Research in the high-stakes era

The federal No Child Left Behind Act (NCLB; 2001), mandating standardized testing in public schools, provides researchers with unprecedented opportunities for scientific comparison. At the same time, the climate of high-stakes testing encouraged by the law merits empirical scrutiny from psychologists across an array of specialties. If researchers wish to advance policy through psychological science, they must take care to construct research designs that are meaningful to policymakers and professionals in other disciplines. The present study used data from 1,450 Virginia schools to provide a model of scientifically grounded research that is also informed by current legal and political contexts. Results indicate that student poverty and geography are associated with differential access to highly qualified teachers, and that differential access to qualified teachers is uniquely associated with performance on high-stakes achievement tests. Psychologists, with their unique training, are encouraged to take a more active role in using NCLB data.     

Animal research in the Journal of Applied Behavior Analysis

This review summarizes the 6 studies with nonhuman animal subjects that have appeared in the Journal of Applied Behavior Analysis and offers suggestions for future research in this area. Two of the reviewed articles described translational research in which pigeons were used to illustrate and examine behavioral phenomena of applied significance (say-do correspondence and fluency), 3 described interventions that changed animals' behavior (self-injury by a baboon, feces throwing and spitting by a chimpanzee, and unsafe trailer entry by horses) in ways that benefited the animals and the people in charge of them, and 1 described the use of trained rats that performed a service to humans (land-mine detection). We suggest that each of these general research areas merits further attention and that the Journal of Applied Behavior Analysis is an appropriate outlet for some of these publications.     

"Constructive" enumeration by chimpanzees (Pan troglodytes) on a computerized task

Two chimpanzees used a joystick to collect dots, one at a time, on a computer monitor (see video-clip in the electronic supplementary material), and then ended a trial when the number of dots collected was equal to the Arabic numeral presented for the trial. Both chimpanzees performed substantially and reliably above chance in collecting a quantity of dots equal to the target numeral, one chimpanzee for the numerals 1–7, and the second chimpanzee for the numerals 1–6. Errors that were made were seldom discrepant from the target by more than one dot quantity, and the perceptual process subitization was ruled out as an explanation for the performance. Additionally, analyses of trial duration data indicated that the chimpanzees were responding based on the numerosity of the constructed set rather than on the basis of temporal cues. The chimpanzees' decreasing performance with successively larger target numerals, however, appeared to be based on a continuous representation of magnitude rather than a discrete representation of number. Therefore, chimpanzee counting in this type of experimental task may be a process that represents magnitudes with scalar variability in that the memory for magnitudes associated with each numeral is imperfect and the variability of responses increases as a function of the numeral's value.

Correlation between menstrual cycle and cognitive performance in a chimpanzee (Pan troglodytes)

Extensive research on human subjects has tried to investigate whether there is a correlation between cognitive performance and the menstrual cycle. Less is known about the relationship between the menstrual cycle and task performance in other cognitive animals. We test whether the secretion of a sex hormone [luteinizing hormone(LH)] influences the performance of cognitive tasks by a female chimpanzee (Pan troglodytes) who is part of a long-term cognition research program. We focus on two cognitive tasks: an "easy task," which consists of simple numerical ordering, and a "difficult task," which combines numerical ordering with memorizing the numerals' spatial location. Data on the performance of these cognitive tasks, urine samples, and sexual swelling over six menstrual cycles showed that the chimpanzee's performance accuracy decreased and that the intertrial interval was longer during the LH-surge of the menstrual cycle, but only for the performance of the difficult task. These performance attributes seem to reflect a decrease in attention or motivation during ovulation. In summary, the cognitive performance of a chimpanzee was disturbed by hormonal changes despite her long-term experience in the tasks.     

Word acquisition reflects lateralization of hand skill

Right hand preference distinguishes Homo sapiens from our closest primate relative, the chimpanzee. Are differences in degrees of handedness associated with differences in the rate of language development? To answer this question, verbal performance is examined in relation to hand skill in a UK national birth cohort dataset. Using 3-D data plots, we show that increasing dominant-hand skill is associated with increasing verbal ability, and stronger lateralization is associated with earlier acquisition of words. Thus, right-handed bias is relevant to the lateralization of language; variation along this dimension may represent species-specific genetic or ‘epigenetic’ diversity.     

Intramuscular electrical stimulation of facial muscles in humans and chimpanzees: Duchenne revisited and extended

The pioneering work of Duchenne (1862/1990) was replicated in humans using intramuscular electrical stimulation and extended to another species (Pan troglodytes: chimpanzees) to facilitate comparative facial expression research. Intramuscular electrical stimulation, in contrast to the original surface stimulation, offers the opportunity to activate individual muscles as opposed to groups of muscles. In humans, stimulation resulted in appearance changes in line with Facial Action Coding System (FACS) action units (AUs), and chimpanzee facial musculature displayed functional similarity to human facial musculature. The present results provide objective identification of the muscle substrate of human and chimpanzee facial expressions- data that will be useful in providing a common language to compare the units of human and chimpanzee facial expression.     

The Ai project: historical and ecological contexts

This paper aims to review a long-term research project exploring the chimpanzee mind within historical and ecological contexts. The Ai project began in 1978 and was directly inspired by preceding ape-language studies conducted in Western countries. However, in contrast with the latter, it has focused on the perceptual and cognitive capabilities of chimpanzees rather than communicative skills between humans and chimpanzees. In the original setting, a single chimpanzee faced a computer-controlled apparatus and performed various kinds of matching-to-sample discrimination tasks. Questions regarding the chimpanzee mind can be traced back to Wolfgang Koehlers work in the early part of the 20th century. Yet, Japan has its unique natural and cultural background: it is home to an indigenous primate species, the Japanese snow monkey. This fact has contributed to the emergence of two previous projects in the wild led by the late Kinji Imanishi and his students. First, the Koshima monkey project began in 1948 and became famous for its discovery of the cultural propagation of sweet-potato washing behavior. Second, pioneering work in Africa, starting in 1958, aimed to study great apes in their natural habitat. Thanks to the influence of these intellectual ancestors, the present author also undertook the field study of chimpanzees in the wild, focusing on tool manufacture and use. This work has demonstrated the importance of social and ecological perspectives even for the study of the mind. Combining experimental approaches with a field setting, the Ai project continues to explore cognition and behavior in chimpanzees, while its focus has shifted from the study of a single subject toward that of the community as a whole.     

Acquisition of auditory–visual intermodal matching-to-sample by a chimpanzee (Pan troglodytes): comparison with visual–visual intramodal matching

A chimpanzee acquired an auditory–visual intermodal matching-to-sample (AVMTS) task, in which, following the presentation of a sample sound, the subject had to select from two alternatives a photograph that corresponded to the sample. The acquired AVMTS performance might shed light on chimpanzee intermodal cognition, which is one of the least understood aspects in chimpanzee cognition. The first aim of this paper was to describe the training process of the task. The second aim was to describe through a series of experiments the features of the chimpanzee AVMTS performance in comparison with results obtained in a visual intramodal matching task, in which a visual stimulus alone served as the sample. The results show that the acquisition of AVMTS was facilitated by the alternation of auditory presentation and audio-visual presentation (i.e., the sample sound together with a visual presentation of the object producing the particular sample sound). Once AVMTS performance was established for the limited number of stimulus sets, the subject showed rapid transfer of the performance to novel sets. However, the subject showed a steep decay of matching performance as a function of the delay interval between the sample and the choice alternative presentations when the sound alone, but not the visual stimulus alone, served as the sample. This might suggest a cognitive limitation for the chimpanzee in auditory-related tasks. Accepted after revision: 11 September 2001 Electronic Publication     

Communication and performance in software development projects

A study of 21 software development (SD) project groups using data from 170 participants holding different positions (engineers, user representatives, project managers) and a quasi-longitudinal design shows that user participation inhibits, and standardization of methods and tools facilitates, effective SD project performance. Over and above these effects, hierarchical regression analysis reveals taskrelated internal communication to predict performance positively. Moderated regression analysis reveals that high communication facilitates project performance more strongly in late stages of the project life-cycle and when standardization of methods and tools is low. Implications for facilitating SD projects' functioning, for future research and theory building, are discussed.     

Assessing Legal Strains and Risk of Suicide Using Archived Court Data

Relatively little is known about legal entanglements and suicide risk. This matched case–control study estimated the risk of suicide associated with legal strains using online court archives, a novel source of exposure data. Court records linked to suicide deaths (N = 315), controls (N = 630), and unintentional injury and poisoning deaths (N = 630) for an urban county from 2000 to 2005 revealed that nearly a third of suicide victims had recent court involvement, twice the proportion among controls. Misdemeanors, car accidents, and foreclosures were each associated with a threefold risk of suicide. Implications for suicide prevention and research are discussed.     

Classifying chimpanzee facial expressions using muscle action

The Chimpanzee Facial Action Coding System (ChimpFACS) is an objective, standardized observational tool for measuring facial movement in chimpanzees based on the well-known human Facial Action Coding System (FACS; P. Ekman & W. V. Friesen, 1978). This tool enables direct structural comparisons of facial expressions between humans and chimpanzees in terms of their common underlying musculature. Here the authors provide data on the first application of the ChimpFACS to validate existing categories of chimpanzee facial expressions using discriminant functions analyses. The ChimpFACS validated most existing expression categories (6 of 9) and, where the predicted group memberships were poor, the authors discuss potential problems with ChimpFACS and/or existing categorizations. The authors also report the prototypical movement configurations associated with these 6 expression categories. For all expressions, unique combinations of muscle movements were identified, and these are illustrated as peak intensity prototypical expression configurations. Finally, the authors suggest a potential homology between these prototypical chimpanzee expressions and human expressions based on structural similarities. These results contribute to our understanding of the evolution of emotional communication by suggesting several structural homologies between the facial expressions of chimpanzees and humans and facilitating future research.     

Withstanding the test of time: The 1978 semantic word norms

This article accompanies the archiving by the Pychonomic Society of the Toglia and Battig (1978) semantic word norms. Herein are outlined the various phases of the project, as well as the challenges that were faced in staying the course during the labor-intensive development of the norms. An examination of the number of citations of this set of norms over the years demonstrates a stable employment of these norms by investigators in many fields. Indeed, a concluding section details the wide range of research topics that have been studied with the use of this extensive set of word ratings. The complete Toglia and Battig article and norms may be downloaded as supplemental materials for this article from brm.psychonomic-journals.org/content/supplemental.     

Employee attitudes,organizational performance,and qualitative factors underlying success

The first phase of this study investigated the relationship between aspects of organizational climate as assessed by a full consensus employee survey and a variety of organizational performance measures. Strong relationships were found for customer satisfaction, absenteeism, second level grievances, safety, and profits in the expected directions. Subsequent comparisons of the groups above or below one standard deviation from the mean score on an employee survey were completed to determine the extent of the differences suggested by the correlations. In the second phase of this study, a qualitative research project was conducted to determine those aspects of the organizational climate that were associated with the high scoring groups but not with either the average or low scoring groups. Strong evidence was found indicating that the presence of a caring, involved leader was the critical ingredient in the organization's success. The implications of these findings for organizational performance improvement efforts are discussed.     

Treatment Outcome Studies With Children: Principles of Proper Practice

This article addresses ethical issues in conducting randomized clinical trials (RCTs) with youth. Ethical considerations that occur prior to treatment (matters of research design, the risk–benefit ratio, issues concerning assent/consent, the influence of payment for participation), during treatment (issues of privacy, protocol adherence, premature termination), and following treatment (needs for posttreatment referrals and/or follow-up contacts, archiving of treatment data) are reviewed. Recommendations, based on empirical evidence and clinical experience, are offered for conducting ethical treatment research with youth and future directions for carrying out research on the ethics of conducting RCTs with youth are offered.     

Psychological Realism, Morality, and Chimpanzees

The parsimonious consideration of research into food sharing among chimpanzees suggests that the type of social regulation found among our closest genetic relatives can best be understood as a form of morality. Morality is here defined from a naturalistic perspective as a system in which self-aware individuals interact through socially prescribed, psychologically realistic rules of conduct which provide these individuals with an awareness of how one ought to behave. The empirical markers of morality within chimpanzee communities and the traditional moral traits to which they correspond are (1) self-awareness/agency; (2) calculated reciprocity/obligation; (3) moralistic aggression/blame; and (4) consolation/empathy.
