The Concept of Trying

It is widely held that whenever someone φs, that person tries to do φ. I examine arguments by B. O'Shaughnessy and J. Hornsby, and considerations by P. Grice in support of that thesis. I argue that none of them are convincing. The remainder of the paper defends an analysis of the concept of trying along the lines opposed by Grice et al. By speaking of someone's trying to φ the speaker leaves the room for failure or the possibility of failure. This account of the function of the word 'try' makes it clear what is wrong with the claim that whenever someone φs, that person tries to do φ. For that claim amounts to saying that every action is either a failure or a possible failure – which clearly one can't say of any action that one has already acknowledged to be successful. Furthermore, whether an action is possibly a failure depends on how much one knows about it. Hence the question whether in itself an action does or does not involve trying is as misguided as the question whether it's intrinsically unexpected. It may be correct for some to describe it as 'an attempt to φ', but incorrect for others.     

Effectiveness of an empirically supported treatment for social phobia in the field

This study examined the effectiveness of individual exposure combined with cognitive restructuring for social phobia in a clinical setting as well as the influence of sample restriction criteria on the effect size. Participants were 217 unselected patients with a primary diagnosis of social phobia who were treated by 57 therapists in four outpatient clinics of the Christoph-Dornier-Foundation of Clinical Psychology in Germany. Results 6 weeks after the end of therapy showed highly significant reductions in social phobic fears and avoidance as well as in general anxiety and symptoms of depression. However, patients who dropped out during therapy reported a significantly higher degree of depression. Results did not differ between the four outpatient clinics and are comparable with the average effect-sizes reported by meta-analytic studies of controlled efficacy research, using selected patients. Also, restricting the sample according to the selection criteria often applied in research settings did not result in higher effect sizes for the applied outcome measures. We conclude that individual cognitive behavioural therapy for social phobia can be transported from research settings to the field of mental health.     

Rate-decreasing effects of the atypical neuroleptic risperidone attenuated by conditions of reinforcement in a woman with mental retardation

Effects of two doses of risperidone on the performance of a matching task under tangible reinforcement and nonreinforcement conditions were measured in a woman with mental retardation. In both conditions, time to complete the task increased and response rates decreased under two doses of risperidone. Accuracy was generally unchanged. These changes were much smaller in the tangible reinforcement condition; thus, reinforcement seemed to protect performance from the rate-decreasing effects of risperidone.     

Emerging issues in developmental eye-tracking research: Insights from the workshop in Hannover,October 2013

This paper provides a summary of the main issues that arose in the final “Discussion” session at the Volkswagen Workshop on Developmental Eye-tracking Research in Reading held in Hannover, Germany, October 2013. The Workshop focused on eye movement research investigating reading development, that is, change in reading performance with age. Development was considered both in relation to children as they changed from novice to more efficient readers, as well as change in reading performance in older adult readers, usually associated with a decline in reading efficiency. The final Discussion session provided an opportunity for attendees to comment on, discuss, and debate any issues that arose in the meeting that they felt were important.     

Individual Differences in the Context‐Dependent Recruitment of Cognitive Control: Evidence From Action Versus State Orientation

The ability to flexibly adapt to deviations from optimal performance is an important aspect of self‐control. In the present study, the authors present first evidence that the personality trait action versus state orientation (Kuhl, 2000) modulates the ability of adaptive control adjustments in response to experienced conflicts. Sixty‐two German individuals with extreme scores on the action‐state dimension performed a response interference task, that is, 31 extreme action‐oriented individuals (30 females; M_age = 20.35 years) and 31 extreme state‐oriented individuals (20 females; M_age = 23.23 years), respectively. Action‐oriented individuals displayed a stronger conflict adaptation effect as evidenced by a stronger reduction of interference on trials following conflict. These results were further corroborated by a correlational analysis including a sample of 105 participants: the higher the score on the action‐state dimension, the lower the interference effect following conflict (i.e., stronger conflict adaptation). The results provide evidence that even low‐level, bottom‐up‐driven processes of self‐control such as conflict adaptation are systematically moderated by individual differences in control modes and provide insights into the cognitive mechanisms underlying action versus state orientation.     

Categories in the pigeon brain: A reverse engineering approach

Pigeons are well known for their visual capabilities as well as their ability to categorize visual stimuli at both the basic and superordinate level. We adopt a reverse engineering approach to study categorization learning: Instead of training pigeons on predefined categories, we simply present stimuli and analyze neural output in search of categorical clustering on a solely neural level. We presented artificial stimuli, pictorial and grating stimuli, to pigeons without the need of any differential behavioral responding while recording from the nidopallium frontolaterale (NFL), a higher visual area in the avian brain. The pictorial stimuli differed in color and shape; the gratings differed in spatial frequency and amplitude. We computed representational dissimilarity matrices to reveal categorical clustering based on both neural data and pecking behavior. Based on neural output of the NFL, pictorial and grating stimuli were differentially represented in the brain. Pecking behavior showed a similar pattern, but to a lesser extent. A further subclustering within pictorial stimuli according to color and shape, and within gratings according to frequency and amplitude, was not present. Our study gives proof‐of‐concept that this reverse engineering approach—namely reading out categorical information from neural data—can be quite helpful in understanding the neural underpinnings of categorization learning.     

Visual selective attention is equally functional for individuals with low and high working memory capacity: Evidence from accuracy and eye movements

Selective attention and working memory capacity (WMC) are related constructs, but debate about the manner in which they are related remains active. One elegant explanation of variance in WMC is that the efficiency of filtering irrelevant information is the crucial determining factor, rather than differences in capacity per se. We examined this hypothesis by relating WMC (as measured by complex span tasks) to accuracy and eye movements during visual change detection tasks with different degrees of attentional filtering and allocation requirements. Our results did not indicate strong filtering differences between high- and low-WMC groups, and where differences were observed, they were counter to those predicted by the strongest attentional filtering hypothesis. Bayes factors indicated evidence favoring positive or null relationships between WMC and correct responses to unemphasized information, as well as between WMC and the time spent looking at unemphasized information. These findings are consistent with the hypothesis that individual differences in storage capacity, not only filtering efficiency, underlie individual differences in working memory.     

Belief,Credence, and Pragmatic Encroachment1

This paper compares two alternative explanations of pragmatic encroachment on knowledge (i.e., the claim that whether an agent knows that p can depend on pragmatic factors). After reviewing the evidence for such pragmatic encroachment, we ask how it is best explained, assuming it obtains. Several authors have recently argued that the best explanation is provided by a particular account of belief, which we call pragmatic credal reductivism. On this view, what it is for an agent to believe a proposition is for her credence in this proposition to be above a certain threshold, a threshold that varies depending on pragmatic factors. We show that while this account of belief can provide an elegant explanation of pragmatic encroachment on knowledge, it is not alone in doing so, for an alternative account of belief, which we call the reasoning disposition account, can do so as well. And the latter account, we argue, is far more plausible than pragmatic credal reductivism, since it accords far better with a number of claims about belief that are very hard to deny.     

The Dual Effects of Organizational Citizenship Behavior: Relationships to Research Productivity and Career Outcomes in Academe

Organizational citizenship behavior (OCB) has been shown to be important for organizational effectiveness, yet less is known about the relationship between OCB and objective outcomes for individuals. We investigate the relationship between OCB and both short-term and longer term outcomes within the context of an outcome-based reward system. We also investigate a type of OCB specific to professional occupations, namely, professional service OCB. Using resource allocation and social exchange theories, we hypothesize that OCB directed internally to the employing organization may have a negative impact on individuals’ productivity and career outcomes while engaging in professional service OCB would be positively related to these outcomes. Results from a survey of 622 faculty members in research universities provide support for these hypotheses. Future research directions are discussed.
