The Gradual Deterioration of Syntax and Semantics in a Patient with Progressive Aphasia

FM is a progressive aphasic patient whose language comprehension we studied over a 4-year period. We developed a variety of implicit and explicit tasks to chart progressive changes in the representation of linguistic knowledge (in particular, syntax and semantics) and the automatic and controlled processes which operate on that knowledge. The representation of FM's semantic knowledge remained essentially intact over the years, but she became increasingly impaired at combining the meanings of words. She also showed progressive impairments in the processes of syntactic combination. Thus, FM's disease resulted in a progressive inability to engage in those combinatorial processes necessary for the normal comprehension of a spoken utterance. This is not a selective deficit in the traditional sense of the term, since aspects of both syntax and semantics are implicated; but it is selective in the sense that other aspects of language comprehension remain intact.     

Symmetry and the devil

F. Mechsner (2004) bases his argument for the primacy of perception on a simplified interpretation of phase transition findings. The authors show that attention to the details of phase transition analysis, as well as consideration of findings from steady-state experiments and the tools of symmetry theory, necessitate a theory of bimanual coordination that includes both perceptual and motor processes.     

Perception, knowledge and freedom in the age of extremes: on the historical epistemology of Ludwik Fleck and Michael Polanyi

This paper deals with Ludwik Fleck??s theory of thought styles and Michael Polanyi??s theory of tacit knowledge. Though both concepts have been very influential for science studies in general, and both have been subject to numerous interpretations, their accounts have, somewhat surprisingly, hardly been comparatively analyzed. Both Fleck and Polanyi relied on the physiology and psychology of the senses in order to show that scientific knowledge follows less the path of logical principles than the path of accepting or rejecting specific conventions, where these may be psychologically or sociologically grounded. It is my aim to show that similarities and differences between Fleck and Polanyi are to be seen in the specific historical and political context in which they worked. Both authors, I shall argue, emphasized the relevance of perception in close connection to their respective understanding of science, freedom, and democracy.     

Memory for Star Trek: the role of prior knowledge in recognition revisited

Prior studies have found robust knowledge effects on recall of text ideas but have seldom found comparable effects on recognition. This inconsistency was examined in light of recent research on the component processes that underlie recognition memory. Using the remember/know paradigm, the authors found that experts made more remember judgments than novices, but only in response to text ideas relevant to their domain of expertise. Using the process-dissociation procedure, the authors found knowledge effects on recollection estimates, but not on familiarity estimates. The authors contend that knowledge effects have been difficult to detect in recognition because knowledge primarily affects recollection, whereas familiarity gives rise to good performance even among novices.     

Insight and strategy in multiple-cue learning

In multiple-cue learning (also known as probabilistic category learning) people acquire information about cue-outcome relations and combine these into predictions or judgments. Previous researchers claimed that people can achieve high levels of performance without explicit knowledge of the task structure or insight into their own judgment policies. It has also been argued that people use a variety of suboptimal strategies to solve such tasks. In three experiments the authors reexamined these conclusions by introducing novel measures of task knowledge and self-insight and using "rolling regression" methods to analyze individual learning. Participants successfully learned a four-cue probabilistic environment and showed accurate knowledge of both the task structure and their own judgment processes. Learning analyses suggested that the apparent use of suboptimal strategies emerges from the incremental tracking of statistical contingencies in the environment.     

Written spelling to dictation: Sound-to-spelling regularity affects both writing latencies and durations

The authors examined the effect of sound-to-spelling regularity on written spelling latencies and writing durations in a dictation task in which participants had to write each target word 3 times in succession. The authors found that irregular words (i.e., those containing low-probability phoneme-to-grapheme mappings) were slower both to initially produce and to execute in writing than were regular words. The regularity effect was found both when participants could and could not see their writing (Experiments 1 and 2) and was larger for low- than for high-frequency words (Experiment 3). These results suggest that central processing of the conflict generated by lexically specific and assembled spelling information for irregular words is not entirely resolved when the more peripheral processes controlling handwriting begin.     

Drivers and outcomes of salespersons’ value opportunity recognition competence in solution selling

Abstract

In B2B markets, firms seek to provide customer solutions instead of merely selling goods or services. As boundary-spanners, salespeople are pivotal for implementing this strategic shift. Yet, extant literature provides limited insights into salesperson’s resources and competencies required for customer solutions, particularly in the early phases of solution selling. This research focuses on salesperson’s value opportunity recognition competence (VOR), which is a central requirement for salespeople to be able to navigate the early phases of solution selling. Analyzing large-scale, multi-level data of 799 salespeople and their respective sales managers in 29 sales organizations, the authors investigate the role of different salesperson resources and work environment characteristics for strengthening their VOR. The authors find that salespeople need both customer and technical knowledge, but customer knowledge is more important. Salespeople also can substitute individual technical knowledge with strong internal relations, but strong customer relations are no substitute for individual knowledge about customers’ business models and processes. Formalization turned out to be a double-edged sword in the context of VOR development, while transformational leadership has positive effects only. The findings bear concrete implications for improving the selection, training, and work environment of solution salespeople.     

Multicultural experience enhances creativity: the when and how

Many practices aimed at cultivating multicultural competence in educational and organizational settings (e.g., exchange programs, diversity education in college, diversity management at work) assume that multicultural experience fosters creativity. In line with this assumption, the research reported in this article is the first to empirically demonstrate that exposure to multiple cultures in and of itself can enhance creativity. Overall, the authors found that extensiveness of multicultural experiences was positively related to both creative performance (insight learning, remote association, and idea generation) and creativity-supporting cognitive processes (retrieval of unconventional knowledge, recruitment of ideas from unfamiliar cultures for creative idea expansion). Furthermore, their studies showed that the serendipitous creative benefits resulting from multicultural experiences may depend on the extent to which individuals open themselves to foreign cultures, and that creativity is facilitated in contexts that deemphasize the need for firm answers or existential concerns. The authors discuss the implications of their findings for promoting creativity in increasingly global learning and work environments.     

Clinical Application of the Couple Adaptation to Traumatic Stress (CATS) Model: A Pragmatic Framework for Working With Traumatized Couples

ABSTRACT

The authors attempt to apply knowledge of traumatization to clinical practice with couple dyads. Elaborating on the Couple Adaptation to Traumatic Stress (CATS) Model (Nelson Goff & Smith, 2005), the authors have worked to bridge the gap between a general understanding of trauma's impact on the couple relationship and couples' treatment. This article facilitates the application of the CATS Model to clinical work with couples impacted by trauma. Incorporating Herman's (1997) traumatic process with the original CATS Model, the authors created a more specific, clinically useful framework for clinicians. The goal of the current article is to provide clinicians with a pragmatic illustration articulating a clinical framework for understanding and treating posttraumaumitc symptoms and processes within the couple relationship. The main implication is that clinicians will be able to conduct effectively guided systemic therapy with distressed couples necessary to generate progress in the treatment of symptomatology and couple functioning of trauma survivors and their partners.     

Science versus the stars: a double-blind test of the validity of the NEO Five-Factor Inventory and computer-generated astrological natal charts

The authors asked 52 college students (38 women, 14 men, M age = 19.3 years, SD = 1.3 years) to identify their personality summaries by using a computer-generated astrological natal chart when presented with 1 true summary and 1 bogus one. Similarly, the authors asked participants to identify their true personality profile from real and bogus summaries that the authors derived from the NEO Five-Factor Inventory (NEO-FFI; P. T. Costa Jr. & R. R. McCrae, 1985). Participants identified their real NEO-FFI profiles at a greater-than-chance level but were unable to identify their real astrological summaries. The authors observed a P. T. Barnum effect in the accuracy ratings of both psychological and astrological measures but did not find differences between the odd-numbered (i.e., favorable) signs and the even-numbered (i.e., unfavorable) signs.     

Self and other obedience estimates: biases and moderators

The authors conducted 2 studies regarding behavior perceptions of "self" and "typical other" in hypothetical replications of S. Milgram's (1963) obedience experiment. In Study 1, participants' knowledge about Milgram's actual results was manipulated. Regardless of knowledge, results demonstrated several specific social and perceptual biases (e.g., the self-other bias; J. D. Brown, 1986), in addition to several general, fundamental lessons of social psychology (e.g., the perseverance of lay dispositionism). Study 2 was designed to explore the possibility that participants' own academic interests and worldview could influence the biases explicated in Study 1. The authors assessed perceptions of both criminal-justice majors and non-criminal-justice majors regarding their perceptions of behaviors of self and typical other. The criminal-justice students' self-other obedience estimates were significantly higher than those of the non-criminal-justice students. Further, the self-other discrepancy for criminal-justice students was significantly smaller than the difference reported by non-criminal-justice majors, suggesting that the criminal-justice students demonstrated the self-other bias significantly less than non-criminal-justice students in this context. The findings indicate that specific social-perceptual biases may have been moderated by career interest and worldview.     

The interaction of the explicit and the implicit in skill learning: a dual-process approach

This article explicates the interaction between implicit and explicit processes in skill learning, in contrast to the tendency of researchers to study each type in isolation. It highlights various effects of the interaction on learning (including synergy effects). The authors argue for an integrated model of skill learning that takes into account both implicit and explicit processes. Moreover, they argue for a bottom-up approach (first learning implicit knowledge and then explicit knowledge) in the integrated model. A variety of qualitative data can be accounted for by the approach. A computational model, CLARION, is then used to simulate a range of quantitative data. The results demonstrate the plausibility of the model, which provides a new perspective on skill learning.     

Domestic Violence

Summary

In this paper, the authors outline their experience in incorporating a curriculum on domestic violence into an urban family practice residency program. Based on the concept that in order to successfully develop such a curriculum, it is necessary to address the “culture of the organization,” joint educational strategies that in-elude resident education as well as faculty development were considered. A research question was designed to inquire as to the difference in the level of knowledge about domestic violence in family practice faculty as compared to residents prior to the introduction of educational strategies. The authors describe curriculum goals and objectives and outline specific teaching methods as well as the evaluation instrument utilized in the study to measure actual difference in knowledge between faculty and residents about domestic violence with a focus specifically on spousal abuse. Their conclusions point to the need for an educational strategy that includes emphasis on the faculty-resident interface which utilizes both traditional and non-traditional integrated formats in order to successfully train residents in the identification and treatment of domestic violence.     

Bioethics and Christian Theology

The authors of this essay suggest that the field of bioethics and Christian theology have a great deal to offer to each other. The authors first argue that representatives from both fields must first make sure that they fully and correctly represent their respective position. In other words, scientists, ethicists, and theologians alike must make sure that they present their fields and not use their knowledge merely for personal gain at the stake of misguiding people. Once this is established, the authors then proceed to show the intimate relationship between Christianity and medicine that has existed throughout the ages. It is a call for a continuation of such a relationship that the authors suggest between bioethics and theology. Through an integration of bioethics and Christian theology, both scientists/physicians and theologians are able to gain greater insight into the human person—a focus in both fields.     

Performance implications of leader briefings and team-interaction training for team adaptation to novel environments

The authors examined how leader briefings and team-interaction training influence team members' knowledge structures concerning processes related to effective performance in both routine and novel environments. Two-hundred thirty-seven undergraduates from a large mid-Atlantic university formed 79 three-member tank platoon teams and participated in a low-fidelity tank simulation. Team-interaction training, leader briefings, and novelty of performance environment were manipulated. Findings indicated that both leader briefings and team-interaction training affected the development of mental models, which in turn positively influenced team communication processes and team performance. Mental models and communication processes predicted performance more strongly in novel than in routine environments. Implications for the role of team-interaction training, leader briefings, and mental models as mechanisms for team adaptation are discussed.     

Behavioral confirmation in social interaction: From social perception to social reality

A perceiver's actions, although based upon initially erroneous beliefs about a target individual may channel social interaction in ways that cause the behavior of the target to confirm the perceiver's beliefs. To chart this process of behavioral confirmation, we observed successive interactions between one target and two perceivers. In the first interaction, targets who interacted with perceivers who anticipated hostile partners displayed greater behavioral hostility than targets whose perceivers expected nonhostile partners. Only when targets regarded their actions as reflections of personal dispositions did these behavioral differences in hostility persevere into their subsequent interactions with naive perceivers who had no prior knowledge about them. Theoretical implications of the behavioral confirmation construct for social perception processes are discussed.     

Linguistic and nonlinguistic priming in aphasia

Studies of real-time processing in aphasia suggest that linguistic symptoms may be due to deficits in activation dynamics rather than loss of linguistic knowledge. To investigate the domain specificity of such processing deficits, we compared performance by Italian-speaking fluent aphasics, nonfluent aphasics, and normal controls in a linguistic priming task (grammatical gender) with their performance in a color-priming task that requires no verbal mediation. Normal or larger than normal color-priming effects were demonstrated in both aphasic groups. Gender priming did not reach significance in either group, even though the patients displayed above-chance sensitivity to gender class and gender agreement in their accuracy scores. The demonstration of spared gender knowledge despite impaired gender priming underscores the utility of on-line techniques in the study of aphasia. The demonstration of spared color priming suggests that priming deficits in aphasia are either (1) specific to speech and language or (2) specific only to those sensorimotor and attentional processes that language shares with other nonlinguistic systems.     

Teamwork in multiteam systems

The authors examined how networks of teams integrate their efforts to succeed collectively. They proposed that integration processes used to align efforts among multiple teams are important predictors of multiteam performance. The authors used a multiteam system (MTS) simulation to assess how both cross-team and within-team processes relate to MTS performance over multiple performance episodes that differed in terms of required interdependence levels. They found that cross-team processes predicted MTS performance beyond that accounted for by within-team processes. Further, cross-team processes were more important for MTS effectiveness when there were high cross-team interdependence demands as compared with situations in which teams could work more independently. Results are discussed in terms of extending theory and applications from teams to multiteam systems.     

The construction of autobiographical memories in the self-memory system

The authors describe a model of autobiographical memory in which memories are transitory mental constructions within a self-memory system (SMS). The SMS contains an autobiographical knowledge base and current goals of the working self. Within the SMS, control processes modulate access to the knowledge base by successively shaping cues used to activate autobiographical memory knowledge structures and, in this way, form specific memories. The relation of the knowledge base to active goals is reciprocal, and the knowledge base "grounds" the goals of the working self. It is shown how this model can be used to draw together a wide range of diverse data from cognitive, social, developmental, personality, clinical, and neuropsychological autobiographical memory research.
