Personality and motivation: Sources of inefficiency in cognitive performance

Impulsivity and anxiety are two dimensions of personality which have strong effects upon the efficiency of cognitive performance. The effects of these two variables depend upon characteristics of the task as well as upon four types of tradeoffs between psychological resources. Tasks may be characterized in terms of their relative requirements for sustained information transfer (SIT), short-term memory (STM), and long-term memory (LTM). Resource tradeoffs may be automatic, strategic, directional, or stylistic. Impulsivity effects on performance involve an automatic arousal-induced tradeoff between SIT and STM, strategic tradeoffs of speed for accuracy, and stylistic differences in persistence. Anxiety effects involve strategic, directional, and stylistic tradeoffs.     

Nonlinear analyses in sales research: theoretical bases and analytical considerations for polynomial models

Despite theoretical bases that may support nonlinear relationships, there is a relative paucity of studies testing these effects in organisational and behavioural research. Theories hypothesising linear associations among variables in sales research found to have low predictive validity are prime candidates for re-conceptualisation with theories predicting nonlinear relationships. In the sales domain, while nonlinear-oriented theories have been advanced and many nonlinear associations have been explored, myriad additional variables may possess theoretically-based nonlinear relationships with key sales-related outcomes. Further, nonlinear integration can be useful in improving linear analyses involving moderation. The purpose of this article is to expound upon and promote the utilisation of theoretically-driven nonlinear analyses in sales research. In this pursuit, the article delineates the rationale for nonlinear examinations and provides an extensive review of nonlinear research conducted in the extant sales literature. Based on this review, theoretical bases used to support nonlinear hypotheses are advanced and types of polynomial tests are identified. Additionally, guidelines in conducting and interpreting main effect and moderated polynomial analyses are provided along with future research opportunities for nonlinear analyses in sales research.     

Learning to Optimize Speed,Accuracy, and Energy Expenditure: A Framework for Understanding Speed-Accuracy Relations in Goal-Directed Aiming

Over the last century, investigators have developed a number of models to explain the relation between speed and accuracy in target-directed manual aiming. The models vary in the extent to which they stress the importance of feedforward processes and the online use of sensory information (see D. Elliott, W. F. Helsen, & R. Chua, 2001, for a recent review). A common feature of those models is that the role of practice in optimizing speed, accuracy, and energy expenditure in goal-directed aiming is either ignored or minimized. The authors present a theoretical framework for understanding speed-accuracy tradeoffs that takes into account the strategic, trial-to-trial behavior of the performer. The strategic behavior enables individuals to maximize movement speed while minimizing error and energy expenditure.

Youth mentoring: The American Dream comes to the UK?

This paper examines the ways in which the North American experience has influenced youth mentoring programmes in the UK and focuses on the theoretical assumptions about young people which have underpinned mentoring interventions. A more critical approach to this North American 'legacy' is required if the value of this form of intervention is to be accurately assessed. The paper argues that an over-reliance by mentoring interventions on developmental paradigms has curtailed their capacity to take account of the wider social context in which young people are making their transitions to adulthood. It is suggested that alternative theoretical frameworks which address the complexity and multiplicity of youth transitions hold more promise for understanding and theorising the role of mentoring in the UK setting. A recent Scottish study of informal mentoring processes attempted to open up these theoretical possibilities by using a framework which recognised young people as active participants and agents. This study revealed that a range of models of mentoring may be in place within informal mentoring relationships. The paper argues that findings from this study demonstrated a need for a more critical approach to the 'classic notion' of mentoring as exclusively a one to one relationship between an adult and a young person. Since mentoring is now a highly popular form of intervention with 'socially excluded' young people these questions about the theoretical base for the concept require urgent attention.     

Coping and defence mechanisms: What are we assessing?

The present research study addresses the disparity between theoretical considerations and empirical evidence regarding the relationships between coping strategies and defence mechanisms. Self‐reported measures of coping and defences were administered to a Romanian adult sample (N = 542; 74.53% female, mean age = 31.28). Using structural equation modelling, models that assumed independence between coping and defences were compared with models that assumed the existence of relationships between the two concepts. Findings identified strong relationships between coping and defences, indicating large common variance between the two concepts. Furthermore, results suggested that coping and defences can be classified into two independent types of adaptation processes. Results of this research study suggested that coping and defences are facets of common adaptation processes.

Evaluating the Utility of MFT Models in the Treatment of Trauma: Implications for Affect Regulation

The purpose of this paper is to discuss polyvagal theory as a theoretical foundation for helping clinicians more effectively treat clients who have experienced major trauma. More specifically, we emphasize that through the use of both modern and post-modern models, marriage and family therapists may use emotion regulation strategies to assist clients in overcoming the negative repercussions of traumatic events. We suggest that the nature of emotional arousal which accompanies trauma alters the physical process by which the body regulates future affective stimuli in ways that are potentially detrimental to human relationships. We then offer a discussion of how a selection of MFT models contain strategies that promote reconnection to self and others that should be utilized with greater precision, ultimately to target the physiological symptoms of trauma-altered emotion regulation processes. Finally, we discuss the need for more specific, process-oriented research that integrates cross-disciplinary theory to contribute to a more intricate and useful understanding of the treatment of trauma in the relational context.     

On the nature and direction of relationships between constructs and measures

Theory development typically focuses on relationships among theoretical constructs, placing little emphasis on relationships between constructs and measures. In most cases, constructs are treated as causes of their measures. However, this causal flow is sometimes reversed, such that measures are viewed as causes of constructs. Procedures have been developed to identify and estimate models that specify constructs as causes or effects of measures. However, these procedures provide little guidance for determining a priori whether constructs should be specified as causes or effects of their measures. Moreover, these procedures address few of the possible causal structures by which constructs and measures may be related. This article develops principles for specifying the direction and structure of relationships between constructs and measures. These principles are illustrated using examples from psychological, sociological, and organizational research.     

A Plan Recognition Model for Subdialogues in Conversations

Previous plan-based models of dialogue understanding have been unable to account for many types of subdialogues present in naturally occurring conversations. One reason for this is that the models have not clearly differentiated between the varoius ways that an utterance can relate to a plan structure representing a topic. In this paper we present a plan-based theory that allows a wide variety of utterance-plan relationships. We introduce a set of discourse plans, each one corresponding to a particular way that an utterance can relate to a discourse topic, and distinguish such plans from the set of plans that are actually used to model the topics. By incorporating knowledge about discourse into a plan-based framework, we can account for a wide variety of subdialogues while maintaining the computational advantages of the plan-based approach.     

A pluralistic framework for counselling and psychotherapy: Implications for research

Historically, training, research and practice in counselling and psychotherapy have been dominated by unitary theoretical models. Although integrative and eclectic positions have been developed as alternatives, these have not been successful in generating research and have resulted in a further proliferation of competing models. In this paper we introduce a ‘pluralistic’ framework for counselling and psychotherapy and discuss the implications of this framework for research. The basic principle of this pluralistic framework is that psychological difficulties may have multiple causes and that there is unlikely to be one, ‘right’ therapeutic method that will be appropriate in all situations—different people are helped by different processes at different times. This pluralistic framework operates as a meta‐theory within which it is possible to utilise concepts, strategies and specific interventions from a range of therapeutic orientations. The framework is structured around three domains—goals, task and methods—by which therapeutic processes can be conceptualised, critically examined and empirically investigated. These domains, and the relationships between them, are outlined and the collaborative relationship at the heart of the pluralistic framework is discussed. The pluralistic framework provides a means for empirical research directly to inform practice and potential lines of empirical inquiry are outlined, along with findings from a recent study of counselling in schools.     

The elusive tradeoff: Speed vs accuracy in visual discrimination tasks

Theoretical models for choice reaction time and discrimination under time pressure must account for Ss’ ability to trade accuracy for increased speed. The fast guess model views these tradeoffs as different mixtures of “all-or-none” strategies, while incremental models assume they reflect different degrees of thoroughness in processing the stimulus. Three experiments sought tradeoffs for difficult visual discriminations, using explicit payoffs to control and manipulate pressures for speed and accuracy. Although guessing was pervasive, the simple fast guess model could be rejected; Experiments II and III obtained tradeoffs even when fast guesses were purged from Ss’ data. Tradeoff functions fit by several formulations revealed: (1) slower rates of increase in accuracy for more similar stimuli, and (2) substantial “dead times” (80–100 msec slower than detection times) before discrimination responses could exceed chance accuracy. Errors were sometimes faster and sometimes slower than correct responses (depending on S’s speed-accuracy trade); the latter effect may reflect a ceiling on S’s achievable accuracy. A final discussion examines implications of the results for models of discrimination under time pressure; it suggests modifications in present models, focusing on the random walk model, and describes an alternative “deadline” model.     

MINIMIZING TRADEOFFS WHEN REDESIGNING WORK: EVIDENCE FROM A LONGITUDINAL QUASI-EXPERIMENT

Although cross-sectional job design research highlights a tradeoff between motivational and mechanistic work design, the redesign literature is more equivocal. We develop a work redesign process that suggests the tradeoffs can be minimized if both motivational and mechanistic approaches are explicitly considered when work is designed and the ultimate outcomes of the design effort (e.g., satisfaction, efficiency, or both) are taken into account when work is redesigned. In a longitudinal quasi-experiment, we examined how jobs can be differentially changed in terms of their motivational and mechanistic properties. Results showed at least partial support for all expected relationships. This suggests that the tradeoffs previously considered inherent in job design may not always occur, particularly if conceptual and methodological consideration is given to their minimization.     

The relevance of attachment theory to a contemporary Jungian view of the internal world: internal working models, implicit memory and internal objects

In this paper I examine the various meanings of the term 'internal object' and the differences between various theoretical models for the formation of internal objects. I suggest that the idea in attachment theory of 'internal working models' emphasizes the internal world as one consisting of unconscious internalized patterns of emotional relationships. The term 'internal object' lacks this clarity and the different meanings it carries within differing theoretical frameworks are a source of confusion. I describe the role implicit memory plays in the formation of 'internal working model's and suggest that these offer us an alternative explanation for unconscious fantasy and for object relationships to that of instinctual drives. This model is then brought to bear on contemporary Jungian concepts of the internal world, with a suggestion that, seen in this light, Jung's formulation of the concept of the complex has many features in common with the 'internal working model' of attachment theory.     

Abducted by Bayesians?

This paper discusses the role of theoretical notions in making predictions and evaluating statistical models. The core idea of the paper is that such theoretical notions can be spelt out in terms of priors over statistical models, and that such priors can themselves be assigned probabilities. The discussion substantiates the claim that the use of theoretical notions may offer specific empirical advantages. Moreover, I argue that this use of theoretical notions explicates a particular kind of abductive inference. The paper thus contributes to the discussion over Bayesian models of abductive inference.     

Gender differences in standards for romantic relationships

Why is it that women often report more problems in their romantic relationships than do men? One explanation apparent in the literature is that women may view different standards as important for relationships than do their male counterparts and, as a consequence, women may be less likely to have their standards met. A second explanation is that while women and men may not differ in terms of the importance they associate with various standards, the experiences they have in their romantic relationships may lead women Lo believe their standards are not fulfilled as often as do men. The current study offers a preliminary test of these two rival explanations and found greater support for the latter. Analyses of two composite measures and more detailed factor-based measures generally indicated that the standards held by women and men involved in heterosexual romantic relationships were rated similar in importance. Women, however, tended to note that their standards were met less fully than did men. Further, compared to men, women reported a greater discrepancy between the importance they associated with various standards and the extent to which the standards were fulfilled in the context of their relationship. The ability of two different theoretical models to predict and explain these findings is discussed, as re the implications of the results for future research.     

Telemedicine in Primary Health: The Virtual Doctor Project Zambia

Physician-researchers are bound by professional obligations stemming from both the role of the physician and the role of the researcher. Currently, the dominant models for understanding the relationship between physician-researchers' clinical duties and research duties fit into three categories: the similarity position, the difference position and the middle ground. The law may be said to offer a fourth "model" that is independent from these three categories. These models frame the expectations placed upon physician-researchers by colleagues, regulators, patients and research participants. This paper examines the extent to which the data from semi-structured interviews with 30 physician-researchers at three major pediatric hospitals in Canada reflect these traditional models. It seeks to determine the extent to which existing models align with the described lived experience of the pediatric physician-researchers interviewed. Ultimately, we find that although some physician-researchers make references to something like the weak version of the similarity position, the pediatric-researchers interviewed in this study did not describe their dual roles in a way that tightly mirrors any of the existing theoretical frameworks. We thus conclude that either physician-researchers are in need of better training regarding the nature of the accountability relationships that flow from their dual roles or that models setting out these roles and relationships must be altered to better reflect what we can reasonably expect of physician-researchers in a real-world environment.
