The effects of self-disclosure and non self-disclosure of stuttering on listeners' perceptions of a person who stutters

The aim of this study was to examine listener perceptions of an adult male person who stutters (PWS) who did or did not disclose his stuttering. Ninety adults who do not stutter individually viewed one of three videotaped monologues produced by a male speaker with severe stuttering. In one monologue, 30 listeners heard the speaker disclose stuttering at the beginning and in another monologue, 30 listeners heard the speaker disclose stuttering at the end. A third group of 30 listeners viewed a monologue where no disclosure of stuttering occurred. After listeners viewed a monologue, they were asked to rate a set of six Likert scale statements and answer three open-ended questions. The results showed that only one of six Likert statements was significantly different across the three conditions. The only statement that was different was that the speaker was perceived to be significantly more friendly when disclosing stuttering at the end of the monologue than when not disclosing stuttering. There were no significant differences between the percentage of positive and negative comments made by listeners across the three conditions. Listeners' comments to each open-ended question showed they were comfortable listening to stuttering with or without disclosure and slightly more than half of the listeners believed their perceptions of the speaker did not change when he disclosed stuttering. The results also showed that the speaker who disclosed stuttering at the beginning of the monologue received significantly more positive listener comments than when he disclosed stuttering at the end of the monologue. Results are discussed relative to comparisons with the study, the clinical relevance of acknowledging stuttering as a component of treatment, and future research on the self-disclosure of stuttering. Educational objectives: The reader will be able to: (1) describe how different groups of listeners perceive and respond to two conditions of self-disclosure of stuttering and one condition involving non self-disclosure of stuttering; (2) summarize the range of listener responses to and benefits of self-disclosure of stuttering; and (3) describe the value of self-disclosure of stuttering for the listener and the speaker.     

How do room and apparatus cues control navigation in the Morris water task? Evidence for distinct contributions to a movement vector

The present study compared the relative influence of location and direction on navigation in the Morris water task. Rats were trained with a fixed hidden or cued platform, and probe trials were conducted with the pool repositioned such that the absolute spatial location of the platform was centered in the opposite quadrant of the pool. Rather than swimming to the platform location, rats swam in the direction that was reinforced during training, resulting in navigation to the relative location of the platform in the pool and search at the appropriate distance from the pool wall. Pool relocation tests revealed disruptions in cued navigation if the cued platform remained at the absolute location, whereas no disruption was observed if the platform remained at the relative location (same direction). The results indicate that direction holds greater influence than does location and further demonstrate that this observation is not altered by the amount of training or time on the platform. The authors propose that navigation in the water task involves a movement vector in which the distal cues and apparatus provide direction and distance information, respectively.     

Item-specific adaptation and the conflict-monitoring hypothesis: a computational model

M. M. Botvinick, T. S. Braver, D. M. Barch, C. S. Carter, and J. D. Cohen (2001) implemented their conflict-monitoring hypothesis of cognitive control in a series of computational models. The authors of the current article first demonstrate that M. M. Botvinick et al.'s (2001) conflict-monitoring Stroop model fails to simulate L. L. Jacoby, D. S. Lindsay, and S. Hessels's (2003) report of an item-specific proportion-congruent (ISPC) effect in the Stroop task. The authors then implement a variant of M. M. Botvinick et al.'s model based on the assumption that control must be able to operate at the item level. This model successfully simulates the ISPC effect. In addition, the model provides an alternative to M. M. Botvinick et al.'s explanation of the list-level proportion-congruent effect in terms of an ISPC effect. Implications of the present modeling effort are discussed.     

A reverse Stroop effect without translation or reading difficulty

It is well known that irrelevant color words affect the time needed to identify the color they are displayed in (the Stroop effect). One major view is that a reverse Stroop effect (RSE)—in which the irrelevant color affects the time needed to identify the word—does not occur unless a translation is needed between domain-specific memory codes. In the present article, we report an experiment in which the reverse Stroop effect was investigated by having subjects identify a colored word at fixation by pointing to a location on the screen containing that word. Although the response was untranslated, an RSE was observed. An account is provided in which the strength of association between a stimulus and a specific response plays a central role.     

Transformation of the discriminative and eliciting functions of generalized relational stimuli

In three experiments, match-to-sample procedures were used with undergraduates to establish arbitrary relational functions for three abstract visual stimuli. In the presence of samples A, B, and C, participants were trained to select the smallest, middle, and largest member, respectively, of a series of three-comparison arrays. In Experiment 1, the B (choose middle) stimulus was then used to train a steady rate of keyboard pressing before the A (choose smallest) and the C (choose largest) stimuli were presented. Participants pressed slower to A and faster to C than to B. Then B was paired with mild shock in a Pavlovian procedure with skin conductance change as the dependent variable. When presented with A and C, 6 of 8 experimental participants showed smaller skin conductance changes to A and larger skin conductance changes to C than to B. In Experiment 2, A was then used as a sample in a match-to-sample procedure to establish an arbitrary size ranking among four same-sized colored circle comparisons. One of the middle circles was then used to establish a steady rate of pressing before the other circles were presented. Five of 6 participants responded slower to the "smaller" circle and faster to the "larger" circle than they did to the "middle" circle. In Experiment 3, A, B, and C were then presented on a series of test trials requiring participants to pick the comparison that was less than, greater than, or equal to the sample. Novel stimuli were included on some trials. Results indicated that the relational training procedures produced derived relations among the stimuli used in training and that these allowed correct inferences of relative size ranking among novel stimuli.     

Spousal caregiver confidence and recovery from ambulatory activity limitations in stroke survivors.

OBJECTIVE: This study examined whether spousal confidence in care-recipient recovery can predict recovery from activity limitations following stroke and how spousal confidence relates to stroke survivor self-efficacy for recovery. DESIGN: A prospective design was used. Measures were gathered from stroke survivor/spouse dyads at two time points, both postdischarge from the hospital following stroke (N=109). MAIN OUTCOME MEASURES: The dependent variable was recovery from ambulatory activity limitations over 6 weeks, as measured by the Functional Limitations Profile. A single spousal confidence item was tailored to an ambulatory behavior that the stroke survivors could not perform at Time 1. RESULTS: Spousal confidence was correlated with ambulation recovery (r=-0.23, p<.05) and stroke survivor self-efficacy for recovery (r=.25, p<.05). Higher spousal confidence was associated with a better recovery and greater stroke survivor self-efficacy for recovery, but not with initial health status or practical support received. CONCLUSION: The relationship between caregiver confidence, care-recipient self-efficacy for recovery, and recovery outcomes needs further elucidation.     

Scott Soames on Gilbert Ryle

In his exceptionally well‐received history of analytic philosophy,¹ Scott Soames presents accounts of the work of Wittgenstein and Ryle that rest on his acceptance of metaphysical preconceptions that these philosophers implicitly question in their writings. Their shared expressive third‐person treatments of the mind, for example, serve to emphasise the inadequacy of Soames's distinction between private mental states and physical states/behaviour, which he regularly employs in assessing their views. His treatment of Gilbert Ryle in particular, reflects the radically different conceptions held by Ryle and Soames of the nature of philosophical investigation. Soames charges Ryle with a failure to recognise the distinction between the necessary and the analytic. He also harbours a clear understanding that philosophical problems arise naturally and directly from “our ordinary ways of thinking,”² where these ways of thinking, the reader discovers, involve metaphysical preconceptions. This is at odds with Ryle's claim that certain category mistakes, playing the role, roughly, of Wittgenstein's misleading pictures, underlie some of the main problems of philosophy. The purpose of this paper is to assess how well Ryle, occasionally aided by Wittgenstein, can be seen to parry Soames's direct onslaught on his work in parts of Dilemmas and in The Concept of Mind.     

Akrasia and the Problem of the Unity of Reason

Joseph Raz and Sergio Tenenbaum argue that the Guise of the Good thesis explains both the possibility of practical reason and its unity with theoretical reason, something Humean psychological theories may be unable to do. This paper will argue, however, that Raz and Tenenbaum face a dilemma: either the version of the Guise of the Good they offer is too strong to allow for weakness of will, or it will lose its theoretical advantage in preserving the unity of reason. 1     

Precipitating Circumstances of Suicide among Active Duty U.S. Army Personnel Versus U.S. Civilians, 2005–2010

To help understand suicide among soldiers, we compared suicide events between active duty U.S. Army versus civilian decedents to identify differences and inform military prevention efforts. We linked 141 Army suicide records from 2005 to 2010 to National Violent Death Reporting System (NVDRS) data. We described the decedents’ military background and compared their precipitators of death captured in NVDRS to those of demographically matched civilian suicide decedents. Both groups commonly had mental health and intimate partner precipitating circumstances, but soldier decedents less commonly disclosed suicide intent.
