Semantic false memories in the form of derived relational intrusions following training

Contemporary behavior analytic research is making headway in characterizing memory phenomena that typically have been characterized by cognitive models, and the current study extends this development by producing "false memories" in the form of functional equivalence responding. A match-to-sample training procedure was administered in order to encourage participants to treat groups of unrelated English words as being interchangeable. Following training, participants were presented with a list of words from within one of the groups for a free recall test and a recognition test. Results showed that participants were more likely to falsely recall and recognize words that had been assigned to the same group as the list words during prior training, relative to words not assigned to the same group and relative to words that co-occurred with list words. These results indicate that semantic relatedness can be experimentally manipulated in order to produce specific false memories.     

Proximal antecedents and correlates of adopted error approach: a self-regulatory perspective

The current study aims to further investigate earlier established advantages of an error mastery approach over an error aversion approach. The two main purposes of the study relate to (1) self-regulatory traits (i.e., goal orientation and action-state orientation) that may predict which error approach (mastery or aversion) is adopted, and (2) proximal, psychological processes (i.e., self-focused attention and failure attribution) that relate to adopted error approach. In the current study participants' goal orientation and action-state orientation were assessed, after which they worked on an error-prone task. Results show that learning goal orientation related to error mastery, while state orientation related to error aversion. Under a mastery approach, error occurrence did not result in cognitive resources "wasted" on self-consciousness. Rather, attention went to internal-unstable, thus controllable, improvement oriented causes of error. Participants that had adopted an aversion approach, in contrast, experienced heightened self-consciousness and attributed failure to internal-stable or external causes. These results imply that when working on an error-prone task, people should be stimulated to take on a mastery rather than an aversion approach towards errors.     

The Validity and Structure of Culture‐Level Personality Scores: Data From Ratings of Young Adolescents

ABSTRACT We examined properties of culture‐level personality traits in ratings of targets (N=5,109) ages 12 to 17 in 24 cultures. Aggregate scores were generalizable across gender, age, and relationship groups and showed convergence with culture‐level scores from previous studies of self‐reports and observer ratings of adults, but they were unrelated to national character stereotypes. Trait profiles also showed cross‐study agreement within most cultures, 8 of which had not previously been studied. Multidimensional scaling showed that Western and non‐Western cultures clustered along a dimension related to Extraversion. A culture‐level factor analysis replicated earlier findings of a broad Extraversion factor but generally resembled the factor structure found in individuals. Continued analysis of aggregate personality scores is warranted.     

Longer-term consequences of anger expression in negotiation: Retaliation or spillover?

Negotiators often concede to angry partners. But what happens when they meet again? According to the spillover hypothesis, negotiators demand less from previously angry partners because they perceive them as tough. According to the retaliation hypothesis, negotiators demand more from previously angry partners because of negative impressions and a desire to get even. Experiment 1 showed that participants demanded less in later negotiations when their partner in a previous negotiation had expressed anger (rather than no emotion) and the later negotiation was with the same (rather than a different) partner. Consistent with the spillover hypothesis, this effect was mediated by inferences regarding the partner’s toughness. Experiment 2 showed that apologies reduce the negative effects of anger on impressions and desire for future interaction. Behavioral reactions were moderated by social value orientation: extending the established might/morality effect, prosocial participants responded cooperatively to an apology, whereas proselfs responded competitively.     

Why Propositions Might be Sets of Truth-supporting Circumstances

Soames (Philos Top 15:44–87, 1987, J Philos Logic 37:267–276, 2008) has argued that propositions cannot be sets of truth-supporting circumstances. This argument is criticized for assuming that various singular terms are directly referential when in fact there are good grounds to doubt this.     

Effect of a kickboxing match on salivary cortisol and immunoglobulin A

The hypothesis that salivary cortisol would increase and salivary immunoglobulin A (IgA) decrease after a kickboxing match was tested among 20 male athletes. Saliva samples collected before and after the match were analyzed. Salivary cortisol and salivary IgA concentrations (absolute concentration, salivary IgAabs) and the secretion rate of IgA (salivary IgArate) were measured by enzyme-linked immunosorbent assay. A Wilcoxon test for paired samples showed significant increases in salivary cortisol from pre- to postmatch. No significant changes were observed in salivary IgAabs or secretory IgArate and saliva flow rate. This study indicates that a kickboxing match might increase salivary concentration and thereafter it could be considered a significant source of exercise-related stress. On the other hand, the effect of a kickboxing match on mucosal immunity seems not to be relevant.     

Gradual growth versus shape invariance in perceptual decision making

A dominant theme in modeling human perceptual judgments is that sensory neural activity is summed or integrated until a critical bound is reached. Such models predict that, in general, the shape of response time distributions change across conditions, although in practice, this shape change may be subtle. An alternative view is that response time distributions are shape invariant across conditions or groups. Shape invariance is predicted by some race models in which the first of several parallel fibers to communicate the signal determines the response. We competitively assess a specific gradual growth model, the one-bound diffusion model, against a natural shape-invariant competitor: shape invariance in an inverse Gaussian distribution. Assessment of subtle shape change versus shape invariance of response time distributions is aided by a Bayesian approach that allows the pooling of information across multiple participants. We find, conditional on reasonable distributional assumptions, subtle shape changes in response time that are highly concordant with a simple diffusion gradual growth model and discordant with shape invariance.     

Maximum-corrected and chance-corrected measures of effect size for the Mantel-Haenszel test

Two measures of effect size are described for the Mantel-Haenszel test. Both measures belong to the r-family of effect size measures. One measure is based on a maximum-corrected model, and the second measure is based on a chance-corrected model.     

Dealing with Diversity: On the Uses of Common Sense in Descartes and Montaigne

This essay attempts to retrieve the notion of ‘common sense’ within the writings of Descartes and Montaigne. I suggest that both writers represent distinct traditions in which the notion is employed. Descartes represents a modernist tradition in which common sense is understood to be a cognitive faculty, while Montaigne represents a humanist tradition in which common sense is understood as a political virtue. I also suggest that both writers work with the notion as a way of responding to diversity in the world. The paper concludes with a discussion of how the notion of common sense employed by Descartes and Montaigne emerges out of the scholastic tradition and the assertion that both writers are responding to the educational consequences of scholasticism. I also discuss how the reconstruction of Descartes in this paper can provide some ground for raising new questions about the Cartesian project and educational philosophy. Finally, I gesture toward the idea that the humanist tradition with its understanding of common sense as political virtue can provide benefit for contemporary responses to diversity.     

Prejudice in the police: On the processes underlying the effects of selection and group socialisation

The principal aim of this study is to determine why police officers are generally found to be more prejudiced towards disadvantaged groups than are the standard population. Two independent processes were expected to account for this effect: Selection and group socialisation. Using a cross‐sectional design (N = 170), firstly, we compared, newly recruited police officers with a control population (selection effect), and secondly, police officers with 1 year of training with the newly recruited ones (group socialisation effect). Results reveal a significant effect of both selection and group socialisation, the two being underlined by distinct processes; right‐wing authoritarianism (RWA) in the case of the former and internalisation of a prejudice norm in the case of the latter. Finally, the results show that group identification moderates the change in internalisation of the prejudice norm. Copyright © 2009 John Wiley & Sons, Ltd.
