Connectionist psycholinguistics: capturing the empirical data

Connectionist psycholinguistics is an emerging approach to modeling empirical data on human language processing using connectionist computational architectures. For almost 20 years, connectionist models have increasingly been used to model empirical data across many areas of language processing. We critically review four key areas: speech processing, sentence processing, language production, and reading aloud, and evaluate progress against three criteria: data contact, task veridicality, and input representativeness. Recent connectionist modeling efforts have made considerable headway toward meeting these criteria, although it is by no means clear whether connectionist (or symbolic) psycholinguistics will eventually provide an integrated model of full-scale human language processing.     

The role of consciousness in attentional control differences in trait anxiety

Trait anxiety has long been associated with impaired selective attention to task-irrelevant threat stimuli, both when threat is presented consciously and outside of awareness. However recent research has suggested broader deficits in selective attention, with poorer ability to ignore supraliminal non-emotional information in anxiety. Here, we investigated whether anxiety could equally be associated with poorer selective attention for non-emotional stimuli in a subliminal context. Participants performed a simple arrow discrimination task, where prior incompatible or compatible response primes were presented before targets either unmasked (supraliminal) or masked (subliminal). While distractor interference was evident in both conditions, trait anxiety was associated with increased task-irrelevant processing only in the supraliminal condition; group effects were eliminated when primes were masked. Our findings are in line with traditional accounts suggesting that differences in selective attention and cognitive control solely modulate conscious distractor processing.     

Making room: Developing reflective capacity through group analytic psychotherapy – in the analyst and in the group. Part one

Abstract

This paper is in two parts. This, the first part, traces the inter-related development of trainee group analyst and training group during the first nine months of the group's life. The influence that personal group analytic psychotherapy, supervision and theoretical learning have on the trainee are also considered in relation to the development of the group and its members, many of whom suffer from narcissistic and borderline disorders. The metaphor of ‘making room’ is used to explore the efforts of analyst and group to contain the chaotic, confused and unbounded projective identifications of its members. In this way, amidst the crowded turbulence of the group, a space begins to open up in which, slowly and painfully, the capacity for reflection may emerge.     

The Difference Between Being and Seeing: The Relative Contribution of Self-Perception and Priming to Behavioral Changes via Digital Self-Representation

Studies in the Proteus Effect (N. Yee & J. Bailenson, 2007 Yee, N. and Bailenson, J. 2007. The proteus effect: The effect of transformed self-representation on behavior. Human Communication Research, 33: 271–290. [Crossref], [Web of Science ®] , [Google Scholar]) have shown that the appearance of avatars (i.e., digital representations of ourselves) can lead to behavioral changes in users. For example, participants in attractive avatars became friendlier to confederate strangers than participants in unattractive avatars. While the Proteus Effect is premised on self-perception theory (D. Bem, 1972 Bem, D. 1972. “Self-perception theory.”. In Advances in experimental social psychology Edited by: Berkowitz, L. Vol. 6, New York: Academic Press. [Crossref] , [Google Scholar])—the notion that we infer our own attitudes by observing ourselves as if from a third party—it is also possible that the previous findings were caused by priming (i.e., behavioral assimilation; J. Bargh, M. Chen, & L. Burrows, 1996 Bargh, J., Chen, M. and Burrows, L. 1996. The automaticity of social behaviour: Direct effects of trait concept and stereotype activation on action. Journal of Personality and Social Psychology, 71: 230–244. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). In our study, we used immersive virtual environment technology to experimentally tease apart embodiment from perception of the same visual stimulus. Our results showed that embodiment produced significantly larger behavioral changes than mere observation of the same visual stimuli. These findings support the claim that our avatars provide a unique lever to behavioral change; however, more work is needed to pin down the exact mechanism behind the effect.     

Connecting DSM-5 Personality Traits and Pathological Beliefs: Toward a Unifying Model

Dissatisfaction with the DSM-IV model of personality disorders has led to the development of alternative conceptualizations, including pathological trait models and models linked to particular theoretical approaches, such as Beck and Freeman’s (1990) cognitive framework. An important issue involves the potential to interweave such models into a single, parsimonious system that combines their distinct advantages. In this study, pathological trait and dysfunctional belief data from 616 individuals in a non-clinical sample were evaluated for commensurability using structural equation modeling. These models can be integrated via five higher-order factors, and that specific dimensions of dysfunctional beliefs can be differentiated based on features of the DSM-5 trait model. Overall, these results suggest that traits provide scaffolding for individual differences in pathological personality, within which dysfunctional beliefs offer specific vectors for clinical intervention in a cognitive framework. Implications of the empirical commensurability of trait and cognitive models are discussed.     

Trends in optimization models of sales force management

In the last half-century, significant advances have been made in directing sales force behavior with the use of optimization and decision models. The present paper both presents the current state-of-the art in sales force decision modeling, and also discusses key issues and trends in contemporary modeling of relevance to sales force researchers. The paper begins by exploring critical concepts regarding the estimation of the sales response function, and then discusses critical problems of endogeneity, heterogeneity, and temporal variation that are faced by modelers in this task. Modern approaches to dealing with these issues are presented. We then discuss areas of importance concerning finding model solutions, including closed form versus simulation, and optimization versus heuristic solutions. The paper next moves to areas of practical importance where models can help, including call planning, sales force size, territory allocation, and compensation design. Finally, we discuss trends that will likely impact on sales force modeling in coming years, including the use of big data and data mining, the possible breakdown of rationality, the rise of the Internet and social media, and the potential of agent-based modeling.     

Driving toward a goal and the goal‐gradient hypothesis: the impact of goal proximity on compliance rate,donation size,and fatigue

Driving toward a goal (DTAG) is a compliance technique derived from observed persuasion practice (e.g., telethons) wherein the persuader utilizes a goal pitch (e.g., “Help us raise $500”) and progress toward a goal (e.g., a tote board) to encourage compliance. It was postulated that DTAG would be more effective than legitimizing a paltry contribution (LPC) at increasing compliance rate, size, and stability. In Study 1, a fundraising field experiment (N = 840 donations) found that LPC garnered significantly more donations and DTAG garnered significantly larger donations. In Study 2, a lab experiment (N = 992 participants) found that LPC garnered more donations at Time 1, DTAG garnered more donations over time (eventually matching LPC), and LPC yielded smaller donations over time.
