Measuring epistemic authority: studies of politicians and professors

Two studies assessed the perception of epistemic authority (denoting a source of information which has a determinative influence on the acquisition of knowledge) by means of a scale (Epistemic Authority Scale) which was constructed for this purpose. The first study showed that individuals perceive political leaders with similar political orientations as greater epistemic authorities than political leaders with different political orientations. In addition, the study investigated the reasons used by the subjects to explain reliance or lack of reliance on political leaders. In general, the responses showed that leaders' expressed opinions and characteristics were important determinants in epistemic authority selection. The second study found that students of statistics departments have a greater tendency to perceive their professors as epistemic authorities in their disciplinary knowledge than students of psychology departments, while the latter are more likely than the former to perceive their professors as epistemic authorities in general knowledge domains. Analysis of the Reason scores for reliance on the professors in the two departments reveals that expertness received the highest ratings.     

ERPs studies of cognitive processing during sleep

In the last few decades, several works on cognitive processing during sleep have emerged. The study of cognitive processing with event related potentials (ERPs) during sleep is a topic of great interest, since ERPs allow the study of stimulation with passive paradigms (without conscious response or behavioural response), opening multiple research possibilities during different sleep phases. We review ERPs modulated by cognitive processes during sleep: N1, Mismatch Negativity (MMN), P2, P3, N400-like, N300-N550, among others. The review shows that there are different cognitive discriminations during sleep related to the frequency, intensity, duration, saliency, novelty, proportion of appearance, meaning, and even sentential integration of stimuli. The fascinating results of cognitive processing during sleep imply serious challenges for cognitive models. The studies of ERPs, together with techniques of neuroimaging, have demonstrated the existence of cognitive processing during sleep. A fundamental question to be considered is if these cognitive phenomena are similar to processing that occurs during wakefulness. Based on this question we discussed the existence of possible mechanisms associated with sleep, as well as the specific cognitive and neurophysiologic differences of wakefulness and sleep. Much knowledge is still required to even understand the conjunction of dramatic changes in cerebral dynamics and the occurrence of cognitive processes. We propose some insights based on ERPs research for further construction of theoretical models for integrating both cognitive processing and specific brain sleep dynamics.     

The role of motivation, responsibility, and integrative complexity in crisis escalation: comparative studies of war and peace crises

Drawing on D. G. Winter's (1993) comparison of 1914 and the Cuban Missile Crisis, the author identified 8 paired crises (1 escalating to war, 1 peacefully resolved). Documents (diplomatic messages, speeches, official media commentary) from each crisis were scored for power, affiliation, and achievement motivation; text measures of responsibility and activity inhibition; and integrative complexity. Aggregated effect-size results show that war crises had significantly higher levels of power motivation and responsibility, whereas peace crises showed trends toward higher integrative complexity and achievement motivation. Follow-up analyses suggested that these results are robust with respect to both sides in a crisis, type of material scored, and historical time. The power motive results extend previous findings, but the responsibility results suggest that responsibility plays a paradoxical role in war. Future research directions are sketched, and the role of psychological content analysis in monitoring the danger of war is discussed.     

The motivational basis of concessions and compromise: archival and laboratory studies

A content analysis system for measuring positive concessions (offering concessions) and negative concessions (rejecting offered concessions) was introduced and validated through an archival study of government-to-government documents from 4 crises, 2 of which escalated to war and 2 of which were peacefully resolved. In the archival documents, concession making was positively associated with affiliation motivation and negatively associated with power motivation. A 2nd, laboratory experimental study confirmed these relationships and demonstrated priming effects of motive imagery and concession making, in a received diplomatic letter, on participants' responses. Finally, the motive imagery and concessions scores in participants' responses were related in predicted ways to their policy choices.     

Toward an integrative approach of cognitive neuroscientific and evolutionary psychological studies of art

This paper examines explanations for human artistic behavior in two reductionist research programs, cognitive neuroscience and evolutionary psychology. Despite their different methodological outlooks, both approaches converge on an explanation of art production and appreciation as byproducts of normal perceptual and motivational cognitive skills that evolved in response to problems originally not related to art, such as the discrimination of salient visual stimuli and speech sounds. The explanatory power of this reductionist framework does not obviate the need for higher-level accounts of art from the humanities, such as aesthetics, art history or anthropology of art.     

Employee commitment and motivation: a conceptual analysis and integrative model

Theorists and researchers interested in employee commitment and motivation have not made optimal use of each other's work. Commitment researchers seldom address the motivational processes through which commitment affects behavior, and motivation researchers have not recognized important distinctions in the forms, foci, and bases of commitment. To encourage greater cross-fertilization, the authors present an integrative framework in which commitment is presented as one of several energizing forces for motivated behavior. E. A. Locke's (1997) model of the work motivation process and J. P. Meyer and L. Herscovitch's (2001) model of workplace commitments serve as the foundation for the development of this new framework. To facilitate the merger, a new concept, goal regulation, is derived from self-determination theory (E. L. Deci & R. M. Ryan, 1985) and regulatory focus theory (E. I. Higgins, 1997). By including goal regulation, it is acknowledged that motivated behavior can be accompanied by different mindsets that have particularly important implications for the explanation and prediction of discretionary work behavior.     

The linguistic and embodied nature of conceptual processing

Recent theories of cognition have argued that embodied experience is important for conceptual processing. Embodiment can be contrasted with linguistic factors such as the typical order in which words appear in language. Here, we report four experiments that investigated the conditions under which embodiment and linguistic factors determine performance. Participants made speeded judgments about whether pairs of words or pictures were semantically related or had an iconic relationship. The embodiment factor was operationalized as the degree to which stimulus pairs were presented in the spatial configurations in which they usually occur (i.e., an iconic configuration, e.g., attic presented above basement). The linguistic factor was operationalized as the frequency of the stimulus pairs in language. The embodiment factor predicted error rates and response time better for pictures, whereas the linguistic factor predicted error rates and response time better for words. These findings were modified by task, with the embodiment factor being strongest in iconicity judgments for pictures and the linguistic factor being strongest in semantic judgments for words. Both factors predicted error rates and response time for both semantic and iconicity judgments. These findings support the view that conceptual processing is both linguistic and embodied, with a bias for the embodiment or the linguistic factor depending on the nature of the task and the stimuli.     

Everyday value conflicts and integrative complexity of thought

This study examined the value pluralism model in everyday value conflicts, and the effect of issue context on complexity of thought. According to the cognitive manager model we hypothesized that respondents would obtain a higher level of integrative complexity on personal issues that on professional and general issues. We also explored the relations of integrative complexity to value priorities, measured by the Schwartz Value Survey, and to emotional empathy. The value pluralism model was not supported by the data collected from 126 university students from social science, business and technology. The cognitive manager model was partially confirmed by data from females but not from males. Concerning value priorities, more complex respondents had higher regard for self-transcendence values, and less complex respondents for self-enhancement values Emotional empathy was also significantly related to complexity score.     

University students' academic performance: An integrative conceptual framework and empirical analysis

Background. The prediction and explanation of academic performance and the investigation of the factors relating to the academic success and persistence of students are topics of utmost importance in higher education. Aims. The main aim of the present study is to develop and test a conceptual framework in a university context, where the effects of achievement goals, self‐efficacy and class size on academic performance are hypothesized to be direct and indirect through study strategies. Sample. Participants were 553 students of different faculties from a university in Spain. Method. Pre‐existing scales were used to develop the questionnaire. Questionnaires were group‐administered in 21 classes during the first 2 weeks of May (i.e. about 1 month before the final examination). At the end of the academic year, students' grades were obtained from professors of each course. Results. Data were analysed through structural equation modelling. The results of the structural model provided support for most of the hypothesized relationships. Achievement goals and self‐efficacy had no direct effects on performance, but results from the model comparison suggested that a mediational model provided a better fit to the data. Conclusions. Our study provides support for the key mediational role of study strategies in the effect of achievement goals and self‐efficacy on academic performance. Self‐efficacy seems to have the strongest indirect effect on performance. Mastery goals play a key role increasing deep processing and effort, and in turn affecting performance. Academic performance tends to diminish with increasing class size.     

Psychological mechanisms of medically unexplained symptoms: an integrative conceptual model

Theories of medically unexplained illness based on the concepts of dissociation, conversion, and somatization are summarized. Evidence cited in support of these theories is described and the conceptual strengths and shortcomings of each approach are considered. It is argued that each of these approaches adds to the understanding of unexplained illness but that none is able to provide a comprehensive explanation of the phenomenon. An integrative conceptual model of unexplained illness based on cognitive psychological principles is then presented. This model attempts to combine existing theoretical approaches within a single explanatory framework, extending previous theory by explaining how compelling symptoms can exist in the absence of organic pathology. The clinical and empirical implications of the model are then considered.     

Theoretical analysis of the cognitive processing of lexical and pictorial stimuli: reading, naming, and visual and conceptual comparisons

This article reviews the research literature on the differences between word reading and picture naming. A theory for the visual and cognitive processing of pictures and words is then introduced. The theory accounts for slower naming of pictures than reading of words. Reading aloud involves a fast, grapheme-to-phoneme transformation process, whereas picture naming involves two additional processes: (a) determining the meaning of the pictorial stimulus and (b) finding a name for the pictorial stimulus. We conducted a reading-naming experiment, and the time to achieve (a) and (b) was determined to be approximately 160 ms. On the basis of data from a second experiment, we demonstrated that there is no significant difference in time to visually compare two pictures or two words when size of the stimuli is equated. There is no difference in time to make the two types of cross-modality conceptual comparisons (picture first, then word, or word first, then picture). The symmetry of the visual and conceptual comparison results supports the hypothesis that the coding of the mind is neither intrinsically linguistic nor imagistic, but rather it is abstract. There is a potent stimulus size effect, equal for both pictorial and lexical stimuli. Small stimuli take longer to be visually processed than do larger stimuli. For optimal processing, stimuli should not only be equated for size, but should subtend a visual angle of at least 3 degrees. The article ends with the presentation of a mathematical theory that jointly accounts for the data from word-reading, picture-naming visual comparison, and conceptual-comparison experiments.     

The cognitive basis of trait anger and reactive aggression: an integrative analysis.

Cognitive processing approaches to personality have gained momentum in recent years, and the present review uses such a cognitive approach to understand individual differences in anger and reactive aggression. Because several relevant cognitive models have been proposed in separate literatures, a purpose of this review is to integrate such material and evaluate the consistency of relations obtained to date. The analysis reveals that processes related to automatic hostile interpretations, ruminative attention, and effortful control appear to be important contributors to individual differences in angry reactivity. Memory accessibility processes, by contrast, failed to exhibit a consistent relationship with trait anger. This review concludes with the proposal of an integrative cognitive model of trait anger and the discussion of several broader issues, including the developmental origins of cognitive processing patterns and plausible links to temperament-based perspectives.     

Syntactic complexity and elaborative processing

Memory for sentences as a function of the syntactic complexity of the sentences was examined. Sentence complexity was varied through a manipulation that involved presenting sentences in either self-embedded forms or more standard forms. Subjects performed an incidental semantic orienting task on a set of sentences varying in complexity and were subsequently tested for their recognition memory of the sentences. In Experiment 1, subjects were tested for their memory of both surface characteristics and meaning of the sentences. There were no differences caused by sentence complexity for memory for meaning. Memory for surface structure, however, was a function of sentence complexity such that there was better memory for the more complex sentences. Experiment 2 replicated the finding that the more complex sentences produced better recognition memory for surface structure. The results are interpreted within a framework that suggests that increased syntactic complexity produces more elaboration, which in turn produces better memory.
