CONTINUOUS RECORDING AND INTEROBSERVER AGREEMENT ALGORITHMS REPORTED IN THE JOURNAL OF APPLIED BEHAVIOR ANALYSIS (1995–2005)

We reviewed all research articles in 10 recent volumes of the Journal of Applied Behavior Analysis (JABA): Vol. 28(3), 1995, through Vol. 38(2), 2005. Continuous recording was used in the majority (55%) of the 168 articles reporting data on free‐operant human behaviors. Three methods for reporting interobserver agreement (exact agreement, block‐by‐block agreement, and time‐window analysis) were employed in more than 10 of the articles that reported continuous recording. Having identified these currently popular agreement computation algorithms, we explain them to assist researchers, software writers, and other consumers of JABA articles.     

Homework Use in Cognitive Therapy for Psychosis: A Case Formulation Approach

Based upon empirically supported cognitive-behavioral treatment approaches, this paper aims to outline the use of homework to enhance the therapeutic relationship, patient motivation, and skills for managing delusions, hallucinations, and negative symptoms. The nature and timing of homework is outlined for the different phases of treatment. Frequent barriers that emerge during the setting and reviewing of homework are described, followed by strategies to enhance motivation and homework compliance. The paper concludes with a demonstration of how homework is optimized within a case formulation approach for persistent symptoms of psychosis.     

The Model Human Processor and the older adult: parameter estimation and validation within a mobile phone task

The authors estimate weighted mean values for nine information processing parameters for older adults using the Card, Moran, and Newell (1983) Model Human Processor model. The authors validate a subset of these parameters by modeling two mobile phone tasks using two different phones and comparing model predictions to a sample of younger (N = 20; M-sub(age) = 20) and older (N = 20; M-sub(age) = 69) adults. Older adult models fit keystroke-level performance at the aggregate grain of analysis extremely well (R = 0.99) and produced equivalent fits to previously validated younger adult models. Critical path analyses highlighted points of poor design as a function of cognitive workload, hardware/software design, and user characteristics. The findings demonstrate that estimated older adult information processing parameters are valid for modeling purposes, can help designers understand age-related performance using existing interfaces, and may support the development of age-sensitive technologies.     

Rethinking neuroethics in the light of the extended mind thesis

The extended mind thesis is the claim that mental states extend beyond the skulls of the agents whose states they are. This seemingly obscure and bizarre claim has far-reaching implications for neuroethics, I argue. In the first half of this article, I sketch the extended mind thesis and defend it against criticisms. In the second half, I turn to its neuroethical implications. I argue that the extended mind thesis entails the falsity of the claim that interventions into the brain are especially problematic just because they are internal interventions, but that many objections to such interventions rely, at least in part, on this claim. Further, I argue that the thesis alters the focus of neuroethics, away from the question of whether we ought to allow interventions into the mind, and toward the question of which interventions we ought to allow and under what conditions. The extended mind thesis dramatically expands the scope of neuroethics: because interventions into the environment of agents can count as interventions into their minds, decisions concerning such interventions become questions for neuroethics.     

A multilevel model analysis of expertise in chess across the life span

The authors examined longitudinal change in chess skill using a multilevel model analysis of a large database of active, elite chess players (N = 5,011). Parameters estimated from quadratic growth curves indicated that the age of peak performance occurs later in life than originally proposed and that this peak is independent of initial skill level. The findings are also consistent with the hypothesis that aging is slightly kinder to the initially more able, who show milder decline past their peak. Higher tournament activity levels predicted higher ratings overall and interacted with age in the initially more able sample, suggesting that activity had smaller effects on rating for older adults. The authors discuss implications of these findings for lifetime changes in skilled performance.     

The Moderating Influence of Personality and Culture on Social Loafing in Typical versus Maximum Performance Situations

The current paper combines research from personality, cultural, social, and work‐ and organizational psychology. More precisely, it addresses the motivating effects of situations that either foster or inhibit social loafing under typical vs maximum performance conditions. It further tests how these effects are moderated by the three individual difference variables of conscientiousness, agreeableness, and openness to experience, and the two cultural dimension variables of collectivism and power distance. Results reveal positive main effects for inherently motivating situations, maximum performance conditions, conscientiousness, agreeableness and collectivism, as well as a significant interaction between the degree to which the situation invites social loafing and the typical vs maximum performance condition. These findings thus confirm a possible overlap between the theories of social loafing and of typical vs maximum performance. Finally, power distance showed a number of surprising interactions that may, in part, account for cultural differences found in the social loafing literature. Implications for theory building, empirical research and practice are discussed.     

Contrasting stochastic and support theory accounts of subadditivity

Numerous studies have found that likelihood judgment typically exhibits subadditivity in which judged probabilities of events are less than the sum of judged probabilities of constituent events. Whereas traditional accounts of subadditivity attribute this phenomenon to deterministic sources, this paper demonstrates both formally and empirically that subadditivity is systematically influenced by the stochastic variability of judged probabilities. First, making rather weak assumptions, we prove that regressive error (or variability) in mapping covert probability judgments to overt responses is sufficient to produce subadditive judgments. Experiments follow in which participants provided repeated probability estimates. The results support our model assumption that stochastic variability is regressive in probability estimation tasks and show the contribution of such variability to subadditivity. The theorems and the experiments focus on within-respondent variability, but most studies use between-respondent designs. Numerical simulations extend the work to contrast within- and between-respondent measures of subadditivity. Methodological implications of all the results are discussed, emphasizing the importance of taking stochastic variability into account when estimating the role of other factors (such as the availability bias) in producing subadditive judgments.     

Suffering and Spirituality in the Poetry of Emily Dickinson

After a brief review of recent accounts of spirituality in its relation to medicine and psychotherapy, Emily Dickinson’s poetry is considered as a springboard to a more specific account of spirituality. While not conventionally religious, she is arguably among the most spiritual of poets inasmuch as her themes of God, love, beauty, and especially death and suffering all depend upon the jarring juxtaposition of embodied human experience and transcendent human significance. Her poems suggest a complex view of the ambiguous relation of suffering to human action and meaning. Psychotherapy is a spiritual process not because it necessarily involves supernatural beings or destinies, but because it represents the struggle between human will and aspiration on the one hand and acceptance of biological and other realities on the other.     

The role of the ‘other’ in national identity: exploring the context‐dependence of the national ingroup stereotype

Analysts from a range of disciplines (especially sociology and social anthropology) highlight the role of the ‘other’ in the construction and definition of national identity. Recently some social psychologists have come to emphasize the inherently relational nature of identity. Drawing upon these recent investigations, the present paper reports a field study investigating the context‐dependent nature of group identity. Using a modified version of the Katz–Braly task, British subjects (n=240) stereotyped two national groups: Americans and British. They did so in two conditions. In the ‘one‐group’ conditions, subjects rated either of the two groups. In the ‘two‐group’ conditions, they rated one whilst also considering the other. Following Oakes, Haslam and Turner (1994) we predicted that whereas subjects' stereotypes of the national outgroup (the Americans) would be unaffected by this manipulation, their stereotype of the national ingroup (the British) would be affected. This prediction was confirmed. We also predicted that the national ingroup stereotype obtained in the ‘two‐group’ condition would be one which was defined in contrast to the American ‘other’ which constituted the comparative context. Using a measure which takes into account the applicability of ingroup‐defining terms to both the ingroup and the outgroup (the diagnosticity measure of stereotyping proposed by McCauley and Stitt, 1978) we show that the ingroup identity definition produced in this condition did indeed differentiate the British from the Americans. The significance of these data for those concerned with the application of social psychological theory to real‐life social problems is discussed. Copyright © 1999 John Wiley & Sons, Ltd.     

A note on the sociological eye and the discovery of a new Durkheim text

The text consisting of recently discovered student notes taken during Émile Durkheim's 1883–1884 lycée lectures on philosophy bears few signs of the social realist perspective with which Durkheim's later work has been identified. Though some scholars have argued that Durkheim's thought was sociological almost from the start, the lectures suggest that Durkheim's sociological eye did not develop until well after the completion of his schooling at the École Normale Supérieure in 1882. This finding is consistent with accounts of Durkheim's intellectual development that stress the importance of his exposure to German scholarship, as well as his consideration of the work of Comte and Rousseau, in the years following 1885. However, these accounts have generally failed to distinguish between the development of Durkheim's philosophy of social realism and the unfolding of the practical worldview that constituted his sociological perspective. This failure is not unique to Durkheimian scholarship, as there exists no general theory of the sociological eye on which historians of ideas can draw. This short essay makes the case that Durkheim's lycée lectures should be used to help develop such a theory. © 1996 John Wiley & Sons, Inc.
