Cognitive control in belief‐laden reasoning during conclusion processing: An ERP study

Belief bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event‐related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual‐process theories of belief bias. However, fMRI studies have tended to focus on conclusion processing, while ERPs studies have been concerned with the processing of premises. In the present research, the electrophysiological correlates of cognitive control were studied among 12 subjects using high‐density ERPs. The analysis was focused on the conclusion presentation phase and was limited to normatively sanctioned responses to valid–believable and valid–unbelievable problems. Results showed that when participants gave normatively sanctioned responses to problems where belief and logic conflicted, a more positive ERP deflection was elicited than for normatively sanctioned responses to nonconflict problems. This was observed from ?400 to ?200 ms prior to the correct response being given. The positive component is argued to be analogous to the late positive component (LPC) involved in cognitive control processes. This is consistent with the inhibition of empirically anomalous information when conclusions are unbelievable. These data are important in elucidating the neural correlates of belief bias by providing evidence for electrophysiological correlates of conflict resolution during conclusion processing. Moreover, they are supportive of dual‐process theories of belief bias that propose conflict detection and resolution processes as central to the explanation of belief bias.     

A dispositional account of practical knowledge

Is knowledge-how, or “practical” knowledge, a species of knowledge-that, or “theoretical” knowledge? There is no comfortable position to take in the debate around this question. On the one hand, there are counterexamples against the anti-intellectualist thesis that practical knowledge is best analysed as an ability. They show that having an ability to ? is not necessary for knowing how to ?. On the other hand, the intellectualist analysis of practical knowledge as a subspecies of theoretical knowledge is threatened by its own set of counterexamples, which convincingly establish that practical knowledge lacks many of the typical characteristics of theoretical knowledge. Most strikingly it does not even appear to require a belief. In this paper, I develop an account of practical knowledge that avoids these counterexamples. It also manages to preserve both the status of such knowledge as a cognitive achievement and its apparently close conceptual relation to abilities. I start with the counterexamples against the necessity of abilities for practical knowledge and show that they fail because they underestimate the cognitive demands of attempts. I then make use of the logic of dispositions to bridge the gap that counterexamples against the necessity of abilities for practical knowledge open. It is argued that, instead of the ability to ?, it is a specific disposition to have the ability to ? that constitutes practical knowledge about ?. The resulting theory is an anti-intellectualist position that preserves essential intellectualist motivations and thus should be satisfactory for proponents of both views.     

The minimum contrast requirements for stereopsis.

A number of researchers have compared the contrast requirements for stereopsis with those for detection of the stereoscopic stimulus, but they have generally failed to allow for the fact that stereopsis requires a detectable stimulus in both eyes at the same time. It is argued that the most appropriate detection threshold for this comparison is that for simultaneous monocular detection (SMD) of the stereoscopic half images. Experiments in which this comparison threshold has been used are summarised and the hypothesis generated that, on using stimuli that are localised in both space and spatial frequency (e.g. Gabor patches or differences of Gaussians), a range of disparities can always be found over which contrast thresholds for depth identification are less than or equal to this SMD threshold (the SMD hypothesis). It is argued that the success of this hypothesis in describing data obtained with these stimuli is consistent with the notions of labelled lines for disparity sign and the size--disparity correlation. Last, experiments are reported in which contrast thresholds for stereoscopic depth identification (front/back) were measured with interocular differences in contrast. The data obtained are consistent with the presence of both inhibitory and excitatory interactions between the eyes when unequal monocular contrasts are presented. The implications of these results and the SMD hypothesis for theories of stereopsis and binocular function are discussed.     

Transitive inference in pigeons: Control for differential value transfer

Transitive inference (TI) effects have been demonstrated in several nonhuman species using a nonverbal version of the task in which A is better than B is represented in a simple simultaneous discrimination, A+B?. Following five-term training (e.g., A+B?, B+C?, C+D?, D+E?), the choice of B over D on test trials is taken as evidence of TI. Recently, differential value transfer from the S+ to the S? in a simultaneous discrimination has been proposed as a noncognitive basis for these effects. Two experiments were conducted to control for differential value transfer. The results suggest that differential value transfer is not the only basis for nonhuman TI performance. An alternative account based on spatial mapping is discussed.     

Nietzsche,postmodernism and the phenomenon of Arvydas Šliogeris in contemporary Lithuanian philosophy

This article is based on the presupposition that postmodern philosophy has been largely influenced by Nietzsche’s writings. The author raises the question of how Nietzsche and postmodern philosophy are interpreted in the contemporary philosophical discourse in Lithuania. The conclusion drawn is that many philosophy critics in Lithuania are interested in Nietzsche’s philosophy (Mickevi?ius, Sodeika, ?erpytyt?, Sverdiolas, Baranova) and in the problems of postmodern philosophy (Ker?yt?, Rubavi?ius, ?ukauskait?, ?erpytyt?, Sverdiolas, Baranova, Norkus). The article also raises a second crucial question: beyond the critics, are there any truly authentic postmodern thinkers in Lithuania? This article’s main hypotheses is that Arvydas ?liogeris’ philosophy is the best and perhaps the only example of original Lithuanian postmodern thought; it is based on, and interconnected with, the deeply inherited roots of existential thought in Lithuanian philosophical culture. The arguments for these hypotheses are as follows: first, ?liogeris is the first philosopher in Lithuania who has tried to reason in an interdisciplinary manner, e.g. trying to overcome the modernistic distinction between philosophy and the arts (especially literature, poetry, and the visual arts); secondly, ?liogeris’s philosophizing is indispensable to his writings—his texts are examples of an experience of writing as thinking and thinking as writing; thirdly, following Deleuze’s presupposition that the philosopher is a creator, one can see this creative aspect in ?liogeris’s approach. His texts show how it is possible to synthesize insights from philosophy and poetry.

Internet use by the socially fearful: addiction or therapy?

The Internet has often been argued to have adverse psychological consequences, such as depression or anxiety symptoms, among "over-users." The present study offers an alternative understanding, suggesting the Internet may be used as a forum for expanding social networks and consequently enhancing the chance of meaningful relationships, self-confidence, social abilities, and social support. An online sample of 188 people was recruited over the Internet, while paper and pencil tests were administered to an offline sample group of 27 undergraduate university students, who were regular Internet users. Subjects completed the Zung Depression Scale (ZDS), Depression, Anxiety and Stress Scales (DASS), Eysenck Personality Questionnaire?Revised Short Scale (EPQ-R Short), Fear of Negative Evaluation (FNE) scale, Internet Use Questionnaire (IUQ), and an Internet Effects Questionnaire (IEQ). Results suggested that there was no relationship between time spent online and depression, anxiety, or social fearfulness. Those who primarily used the Internet for online chat believed that the Internet is psychologically beneficial to them, but also believed that frequent Internet users are lonely and that the Internet can be addictive. It is argued that "chat" users who are socially fearful may be using the Internet as a form of low-risk social approach and an opportunity to rehearse social behavior and communication skills, which, may help them improve interaction with offline, face-to-face, social environments.     

Wundt,Völkerpsychologie,and experimental social psychology

Wilhelm Wundt distinguished between "experimental psychology" and Volkerpsychologie. It is often claimed that Wundt maintained that social psychological phenomena, the subject matter of V?lkerpsychologie, could not be investigated experimentally but must be explored via comparative-historical methods. In this article it is argued that it is doubtful if many of the passages usually cited as evidence that Wundt held such a view actually such such a view. It is also argued that if Wundt did hold such a view, it was inconsistent with his own general theoretical position and methodological practice. It is suggested that it is anachronistic to attribute such a view to Wundt, because he appears to have had little interest in the experimental analysis of the synchronic social dynamics of psychological processes. Most of Wundt's arguments about the inappropriateness of experimentation were directed against the introspective analysis of diachronic historical processes.     

Assimilation and contrast in organizational justice: The role of primed mindsets in the psychology of the fair process effect

This paper focuses on the psychology of the fair process effect (the frequently replicated finding that perceived procedural fairness positively affects people's reactions). It is argued that when people have received an outcome they usually assimilate their ratings of outcome fairness and affect toward their experiences of procedural fairness. As a result, ratings show fair process effects. It is also possible, however, that when people have received their outcome they compare this outcome to the procedure they experienced: Is the outcome better or worse than the procedure? A result of this comparison process may be that contrast effects are found such that higher levels of procedural fairness lead to more negative ratings of outcome fairness and affect. Research findings suggest that when comparison goals have been primed, contrast effects indeed can be found. The implications for the psychology of the fair process effect and organizational behavior are discussed.     

Pattern specificity in the effect of prior Δƒ on auditory stream segregation

During repeating sequences of low (A) and high (B) tones, perception of two separate streams ("streaming") increases with greater frequency separation (Δ?) between the A and B tones; in contrast, a prior context with large Δ? results in less streaming during a subsequent test pattern. The purpose of the present study was to investigate what aspects of the context pattern are necessary for this context effect to occur. Simply changing the B-tone frequency without an alternating A tone present was not sufficient to cause the effect of prior Δ?, but rather a melodic change between A and B tones was necessary. We further investigated the extent to which the context and test patterns needed to have similar rhythms (xxx-xxx-) and melodies (up-down-flat-up-down), and found that a maximal prior-Δ? effect occurred when the rhythmic patterns of the context and test were similar, regardless of the melodic structure. Thus, the effect of prior Δ? on streaming depended on the presence of (1) at least one melodic change in the context, and (2) similar rhythmic patterns in the context and test.     

Effects of Temporal Lobe Lesions on Retrograde Memory: A Critical Review

Scientific interest in retrograde memory has grown considerably over the last two decades. Studies have demonstrated that several brain regions, including the temporal lobes, participate in the formation, maintenance and storage of past memories. Different patterns and extents of retrograde memory deficits have been recorded in patients with temporal lobe lesions. It has been argued that the pattern of retrograde memory deficits is determined not only by the side and specific location of lesion within this region, but also by methodology, medical variables (such as etiology or seizure history), and coexisting cognitive deficits. In this paper we will review published case and group studies of patients with temporal lobe lesions to evaluate the impact of these factors on retrograde memory.

Problematizing culture: Discourses on integration in Norway

How does one, in a society which traditionally has been perceived as homogenous and egalitarian, debate issues of immigration and increasing cultural diversity? This article analyses the notion of integration as it has been used and constructed in Norwegian politics from the 1970s until today. It is argued that culture has emerged as an increasingly problematic dimension in integration policy and public debate. While cultural diversity must be accommodated and celebrated, certain cultural practices, especially in relation to women, have also appeared as increasingly threatening to what is considered as fundamental values in Norwegian society.     

Communicative intentions and language: evidence from right-hemisphere damage and autism.

In this review article, it is argued that the wide range of communicative deficits that have been noted in both individuals with damage to the right cerebral hemisphere (RHD) and high-functioning individuals with autism may stem from difficulties appreciating the importance of their interlocutor's communicative intentions (CIs). It is also argued that the abnormal semantic development noted in infants with RHD and autism may be related to difficulties in appreciating CIs as well. Finally, it is suggested that the CIs hypothesis may provide an avenue for integrating a number of theoretical suggestions that have been made regarding the right hemisphere's contributions to communicative competence.     

Coding of nonsense vs the detection of patterns

Two theories are contrasted: coding information into arbitrary characters vs extracting patterns from a flux of stimulation. It is argued that coding is the process people use to memorize nonsense and, for that reason, is a poor model for the applied psychology of learning. The contrasting idea, that Ss perceive patterns and extract information. can be used to improve education by leading teachers to organize their material. It is also argued that most demonstrations of coding can be interpreted as examples of pattern perception.     

Optimized Split-Half Reliability for the Bender Visual Motor Gestalt Test: Further Evidence for the Use of the Maximization Procedure

Bender-Gestalt protocols from a clinical sample (N = 100) were scored according to the Pascal-Suttell method and γ?11? derived for all possible split-half combinations (n = 35). The distribution of these 35 reliability coefficients proved to be negatively skewed, justifying the use of the maximum split-half reliability rather than the usual odd-even or alpha coefficients. The maximized γ?11?, using only eight designs, was .72, which was higher than has heretofore been reported. Implications of low ns and negative skews for correlational distributions are discussed, and the maximization procedure is recommended even for psychometric tests when the number of items is low.     

Cybernetics and mind‐body problems 1

It is asked to what extent answers to such questions as ‘Can machines think?’, ‘Could robots have feelings?’ might be expected to yield insight into traditional mind‐body questions. It has sometimes been assumed that answering the first set of questions would be the same as answering the second. Against this approach other philosophers have argued that answering the first set of questions would not help us to answer the second. It is argued that both of these assessments are mistaken. It is then claimed, although not argued in detail, that the following three approaches to the first set of questions are mistaken: (1) machines (and robots) obviously cannot think, feel, create, etc., since they do only what they are programmed to do; (2) on the basis of ah analysis of the meaning of the words ‘machine’ ('robot’, ‘think’, ‘feel’, etc.) we can see that in principle it would be impossible for machines (or robots) to think, feel, create, etc.; (3) machines (and robots) obviously can (or could) think, feel, etc., since they do certain things which, if we were to do them, would require thought, feeling, etc. It is argued that, once it is seen why approach (2) is mistaken, it becomes desirable to decline ‘in principle’ approaches to the first set of questions and to favor ‘piecemeal investigations’ where attention is centered upon what is actually taking place in machine technology, the development of new programming techniques, etc. Some suggestions are made concerning the relevance of current computer simulation studies to traditional mind‐body questions. A new set of questions is proposed as a substitute for the first set of questions. It is hoped that attempts to answer these may provide us with new and detailed portraits of the mind‐body relationship.     

Emotional range and value orientation: toward a cognitive view of emotionality

This study focused on emotional range--a personality variable introduced to the study of emotion. It is argued that individual differences in emotional responsiveness need to be described and analyzed not only in terms of emotional intensity but also in terms of emotional range. What are some of the factors that influence an individual's range of emotional experiences? Do cognitive factors play a significant role? Questions such as these were central to the present investigation. In accordance with recent cognitive formulations of emotion, we hypothesized that individual differences on the emotional range variable would be associated with differences in value orientations. Lending support to this proposition, the results revealed a pattern of emotional range--value associations that challenge the prevailing view of emotionality as intimately linked with primitivism and impulsivity. At the same time, the findings strongly suggest that emotionality cannot be understood as divorced from a person's mental life. Implications of the findings for the development of a cognitively oriented approach to the study of individual differences in emotional dispositions are discussed.     

Loss of negative priming following sleep deprivation

It has been argued that one night of sleep loss in young healthy adults produces changes similar to that associated with normal, healthy ageing—in particular, that young sleep-deprived adults perform similarly to 60-year-old sleep-satiated adults on some tasks of frontal lobe function. This proposition was examined using a protocol viewed by many to be a direct probe of nonvolitional attention mechanisms associated with frontal lobe function. A negative priming (NP) procedure was used to compare performance between non-sleep-deprived (NSD) and sleep-deprived (SD, 34 hr) young, healthy adults. This protocol allowed for exploration of two theories of the NP effect based on inhibitory or memorial processes. Under conditions believed to facilitate inhibitory processes a normal NP effect was found for NSD(16 ms) and SD (9 ms) participants. Under conditions believed to rely on memorial processes there was no NPeffect following SD, compared with a normal NP effect for NSD participants (11 ms). Distractor interference was also greater following SD. These findings do not suggest a similar pattern of change following sleep loss in healthy young adults to that of normal, healthy, non-sleep-deprived aged groups.
