Effects of perspective and belief on analytic reasoning in a scientific reasoning task

The purpose of these studies was to test the hypothesis that changing perspectives from one's own to another's promotes the engagement of analytic processing and, in turn, reduces the impact of beliefs. In two experiments participants evaluated research vignettes containing belief-consistent and belief-inconsistent conclusions, and indicated whether the data supported a correlation between two variables. Consistent with our hypothesis, the tendency to endorse correlations consistent with prior belief was reduced when participants evaluated the data from the researcher's perspective relative to their own. We also administered the Actively Open Minded Thinking (AOT) scale (Stanovich & West, 2007, 2008), which did not predict belief effects on our task. We did however observe that the AOT was reliably associated with different response strategies: high AOT scorers were more inclined to choose ambiguous response options, such as “no conclusion is warranted”, whereas low scorers evinced a preference for more determinate options (e.g., there is no relationship between the two variables). We interpret our findings in the context of dual process theories of reasoning and from a Bayesian perspective.     

An evaluation of self-esteem and impression management theories of anticipatory belief change

The predictions of self-esteem and impression management theories of anticipatory belief change were examined as a function of whether or not subjects were reminded that their preexperimental attitudes has been assessed, the source of the expected persuasive communication (expert vs. peer), and whether or not explicit instructions were given regarding the experimenter's concern with opinion change. Anticipatory shifts changed as a function of an interaction of all three variables. In the Reminder conditions, subjects changed their attitudes toward a peer's position when the experimenter explicitly referred to opinion change. In the No Reminder conditions, subjects shifted toward an expert when the instructions were explicit and toward a peer when the instructions were implicit. The results were discussed as qualifying previous research in this area and as problematic for both self-esteem and impression management approaches to anticipatory shifts.     

Effects of face configuration change on shape perception: a new illusion

We report two experiments indicating that varying the configuration of face features changes perception of an oval aperture windowing the face: as the eyes and mouth of a frontal-view face photograph are moved vertically toward face boundaries, the oval appears increasingly clongated, taller, and narrower; when eyes and mouth are moved toward the nose, the oval appears increasingly rounder, shorter, and wider. This shape illusion is maximised when faces appear upright within the oval and major face features (eyes, nose, and mouth) appear in their correct relative locations. These results establish that processing of a face configuration can affect perception of a geometric shape that shares visual space with a face. Whether the illusion is face-specific or a special case of a more general geometric illusion is discussed.     

Letters of Recommendation: Controversy and consensus from expert perspectives

Letters of recommendation (LORs) are a widely used selection tool with many issues associated with their use. To address some of these issues, 575 professionals in personnel‐related professions reported their experiences with LORs. We separated items into consensus, polarized, or neither categories. Experts reached consensus that letter inflation is a problem that may never be alleviated and that more weight is placed on letters written by someone the reader knows or from a prestigious institution or organization. Most items were polarized, suggesting substantial controversy in the field regarding LORs. Some items originally polarized reached consensus within profession (academic vs applied). Academic professionals reported using LORs more and placing more weight on their contents than applied professionals. Implications discussed include recommendations for future research and practice, such as the appropriate use of LORs, LOR formats, and training.     

Climate quality and climate consensus as mediators of the relationship between organizational antecedents and outcomes

Research has shown that climate quality (average climate ratings) is related to organizational antecedents and outcomes, but researchers have yet to examine climate consensus (the variance of climate ratings). Similarly, studies have investigated typical behavior (members' average performance), but have neglected behavioral similarity (within-group variance). Data from 1,196 members in 180 organizations were used to test relationships of climate quality and consensus with organizational antecedents and outcomes. Climate quality and consensus both had significant correlations with organizational antecedents and outcomes, but climate consensus did not contribute a significant increment to the prediction of organizational outcomes. Finally, quality mediated many relationships between organizational antecedents and outcomes.     

Processes of change in a school-based mindfulness programme: cognitive reactivity and self-coldness as mediators

The underlying mechanisms of the effectiveness of mindfulness-based interventions for emotional well-being remain poorly understood. Here, we examined the potential mediating effects of cognitive reactivity and self-compassion on symptoms of depression, anxiety and stress using data from an earlier randomised controlled school trial. A moderated time-lagged mediation model based on multilevel modelling was used to analyse the data. The findings showed that post-treatment changes in cognitive reactivity and self-coldness, an aspect of self-compassion, mediated subsequent changes in symptoms of depression, anxiety and stress. These results suggest that cognitive reactivity and self-coldness may be considered as transdiagnostic mechanisms of change of a mindfulness-based intervention programme for youth.     

When rock bottom rocks your world: Crisis of belief as a catalyst for change

An experience of severe difficulty can turn the world upside-down, causing individuals to question important beliefs with which they identify. This phenomenon, which we label as Crisis of Belief (COB), amalgamates the disparate conceptualizations of crisis that exist across several subdisciplines of psychology. Unlike existing ideas of crisis, COB distinguishes itself from stress or trauma alone, and is a clearly specified construct that lends itself to practical operationalization and study. Thus, COB addresses a key gap in literature and offers unique value for understanding how hardship that affects closely held beliefs can catalyze change. We conclude by describing the potential utility of COB as a predictor of both positive (e.g., life satisfaction) and negative (e.g., depression) outcomes and the pressing need for a validated measure.     

Temporal perception in closed-skill sports: An experimental study on expert swimmers and runners

The cognitive benefits of closed-skill sports practice have so far been scantily investigated. Here, we thus focused on the potential impact of swimming and running - two sports that highly rely on a precise control of timing - on time processing. To investigate the impact of these closed-skill sports on time perception and estimation, three groups of participants (for a total of eighty-four young adults) took part in the present study: expert swimmers, expert runners, and non-athletes. The ability to process temporal information in the milliseconds and seconds range was assessed through a time reproduction and a finger-tapping tasks, while a motor imagery paradigm was adopted to assess temporal estimation of sport performance in a wider interval range. We also employed the Vividness of Movement Imagery Questionnaire to assess the individual's ability of motor imagery. Results showed that closed-skill sports, specifically time-related disciplines, enhance motor imagery and time perception abilities. Swimmers were more accurate and consistent in perceiving time when compared to runners, probably thanks to the sensory muffled environment that leads these athletes to be more focused on the perception of their internal rhythm.     

The anticipated belief differences theory of prejudice: Analysis and evaluation

The main supporting evidence for Rokeach's theory of prejudice (the Anticipated Belief Differences Theory of Prejudice) comes from the strong belief effects obtained in a simple Race/Belief manipulation. Analysis shows that the theory is unfalsifiable with this paradigm and is therefore neither tested nor confirmed by the many studies purporting to do so. The Belief-undefined/Belief-partially-defined manipulation of Stein, Hardyck and Smith (1965) does test the theory. However, these authors' conclusion that favourable evidence was obtained is incorrect owing to the use of an inappropriate statistic. Although race effects can be incorporated within a theory of belief prejudice it is equally possible to incorporate belief effects within any theory of prejudice which is contingent on an initial categorization into in-group and out-group. An empirical distinction between Rokeach's theory and other theories of prejudice can be made using a Belief-undefined/Belief-partially-defined manipulation. Finally the theoretical adequacy of Rokeach's theory is discussed in terms of more general characteristics of prejudice.     

Stability and change of attachment representations during emerging adulthood: An examination of mediators and moderators of change

Using Bartholomew’s model of attachment (K. Bartholomew, 1990; K. Bartholomew & L. Horowitz, 1991), we explored stability and change of attachment in a group of young adults graduating from university and examined reasons for change of attachment. Consistent with previous research, we found that attachment dimensions were moderately stable; however, several variables predicted change. We explored the effect of changing relationship status and parental divorce on attachment and found that individuals who remained single reported lower stability of avoidance over time. Next, we tested whether distress reported before the transition would mediate stability of attachment. The results provided some support for J. Bowlby’s (1969/1982) proposal that distress would be associated with stability and change of attachment. We found that participants who reported low distress at Time 1 (T1) were more likely to report changes in attachment anxiety than participants who reported high distress at T1.     

Radical views on cognition and the dynamics of scientific change

Radical views on cognition are generally defined by a cluster of features including non-representationalism and vehicle-externalism. In this paper, I concentrate on the way radical views on cognition define themselves as revolutionary theories in cognitive science. These theories often use the Kuhnian concepts of “paradigm” and “paradigm shift” for describing their ambitions and the current situation in cognitive science. I examine whether the use of Kuhn’s theory of science is appropriate here. There might be good reasons to think that cognitive science is in a situation of foundational crisis, but that does not entail that the classical paradigm (computationalism) is currently displaced to the benefit of a new paradigm. Larry Laudan’s theory of research traditions is more enlightening than Kuhn’s theory for describing the scope and ambitions of radical views on cognition, and their relations with an anti-intellectualist tradition in philosophy.

     

Metaphor as Argument: Rhetorical and Epistemic Advantages of Extended Metaphors

This paper examines from a cognitive perspective the rhetorical and epistemic advantages that can be gained from the use of (extended) metaphors in political discourse. We defend the assumption that extended metaphors can be argumentatively exploited, and provide two arguments in support of the claim. First, considering that each instantiation of the metaphorical mapping in the text may function as a confirmation of the overall relevance of the main core mapping, we argue that extended metaphors carry self-validating claims that increase the chances of their content being accepted. Second, we show how the recognition of an extended metaphor’s sophistication and relevance (on behalf of the addressee) can benefit the speaker’s perceived competence (ethos). We then assess whether these two arguments measure against the dual epistemic monitoring postulated in the notion of epistemic vigilance (i.e., assessment of the source of a message and assessment of the message) and conclude that extended metaphors may fulfil the requirements of epistemic vigilance and lead to the stabilisation of a belief. We illustrate our account with an analysis of the extended metaphor of the USA as an empire found in a political pamphlet written by the Swiss politician Oskar Freysinger.     

Biased information processing in the escalation paradigm: information search and information evaluation as potential mediators of escalating commitment

Escalation of commitment denotes decision makers' increased reinvestment of resources in a losing course of action. Despite the relevance of this topic, little is known about how information is processed in escalation situations, that is, whether decision makers who receive negative outcome feedback on their initial decision search for and/or process information biasedly and whether these biases contribute to escalating commitment. Contrary to a widely cited study by E. J. Conlon and J. M. Parks (1987), in 3 experiments, the authors found that biases do not occur on the level of information search. Neither in a direct replication and extension of the original study with largely increased test power (Experiment 1) nor under methodologically improved conditions (Experiments 2 and 3) did decision makers responsible for failure differ from nonresponsible decision makers with regards to information search, and no selective search for information supporting the initial decision or voting for further reinvestment was observed. However, Experiments 3 and 4 show that the evaluation of the previously sought information is biased among participants who were responsible for initiating the course of action. Mediation analyses show that this evaluation bias in favor of reinvestment partially mediated the responsibility effect on escalation of commitment.     

The dynamics of motivated perception: Effects of control and status on the perception of ambivalent stimuli

Previous studies on attentional biases often show contradictory results. This suggests that important moderating variables have been neglected so far. We suggest that (1) control over potential consequences and (2) satisfaction with the current status are important factors that need to be considered. We explored the influence of these variables using a colour classification task, where colours are associated with financial gains and losses. Data were analysed with hierarchical logistic regression models and with stochastic diffusion models. The latter approach has the special advantage that it allows separating perceptual and judgemental biases. Results show an overall positive judgemental bias. In the absence of control, this positivity bias increases with the amount of money that has been gained, whereas the opposite pattern is present when dangers can be controlled. In the second experiment, no general feedback was given, which led to an increasing negativity bias. Results are discussed within an action theoretic framework.     

Categorical perception: effects of the extent and rate of spectral change

ABSTRACT

Two experiments evaluated a potential explanation of categorical perception (CP) for place of articulation – namely, that listeners derive limited information from rapid spectral changes. Experiment 1 examined vowel context effects for /b/–/d/ continua that included consonant–vowel tokens with F2 onset frequencies that varied systematically from the F2 frequencies of their corresponding steady-states. Phoneme categorisation sharply shifted with F2 direction at locations along the continuum where discrimination performance peaked, indicating CP. Experiment 2 compared findings for a replicated condition against conditions with vowels reduced to match consonant duration or consonants extended to match vowels. CP was similarly obtained for replicated and vowel-reduced conditions. However, listeners frequently perceived diphthongs centrally on the consonant-extended continuum. Some listeners demonstrated CP, although aggregate performance appeared more continuous. These experiments indicate a model based upon the perceived direction of frequency transitions.     

Effects of dialect on merger perception: ERP and behavioral correlates

Native speakers of a language are often unable to consciously perceive, and have altered neural responses to, phonemic contrasts not present in their language. This study examined whether speakers of dialects of the same language with different phoneme inventories also show measurably different neural responses to contrasts not present in their dialect. Speakers with (n=11) and without (n=11) an American English I/E (pin/pen) vowel merger in speech production were asked to discriminate perceptually between minimal pairs of words that contrasted in the critical vowel merger and minimal pairs of control words while their event-related potential (ERPs) were recorded. Compared with unmerged dialect speakers, merged dialect speakers were less able to make behavioral discriminations and exhibited a reduced late positive ERP component (LPC) effect to incongruent merger vowel stimuli. These results indicate that between dialects of a single language, the behavioral response differences may reflect neural differences related to conscious phonological decision processes.
