Stressful Life Events: A Revision and Update of the Social Readjustment Rating Scale

The widely used and cited Social Readjustment Rating Scale developed by Holmes and Rahe (1967) was comprehensively revised and updated. The new instrument, containing 51 major life events, was administered to a national sample of 5000. Respondents were asked to rate the stressfulness of each life event on a 1–100 scale. Completed surveys were returned by 3122 individuals (62.4%). Responses were analyzed using repeated measures MANOVA and profile analysis. Major results included: (a) statistically and practically significant differences in mean ratings for the 51 life events; (b) five overlapping themes in the top 20 rated life events—death and dying, healthcare, crime and the criminal justice system, financial/economic issues, and family-related issues; and (c) an amazing level of agreement concerning perceived life event stressfulness, regardless of gender, age, or income level.     

Life satisfaction across adulthood: different determinants at different ages?

It is likely that with aging and changing life circumstances, individuals’ values shift in systematic ways, and that these shifts may be accompanied by shifts in the determinants of their subjective judgments of well being. To examine this possibility, the relations among the Satisfaction With Life Scale (SWLS) and a number of personality, affect, demographic, and cognitive variables were examined in a sample of 818 participants between the ages of 18 and 94. The results indicated that although many variables had significant zero-order correlations with the SWLS, only a few variables had unique utility in predicting life satisfaction. Invariance analyses indicated that while the qualitative nature of life satisfaction remains constant across adult age, the influence of fluid intelligence on judgments of life satisfaction declines with age. In contrast, negative affect is negatively associated with life satisfaction consistently across the adult age span.     

Brain activity in adults who stutter: similarities across speaking tasks and correlations with stuttering frequency and speaking rate

Many differences in brain activity have been reported between persons who stutter (PWS) and typically fluent controls during oral reading tasks. An earlier meta-analysis of imaging studies identified stutter-related regions, but recent studies report less agreement with those regions. A PET study on adult dextral PWS (n = 18) and matched fluent controls (CONT, n = 12) is reported that used both oral reading and monologue tasks. After correcting for speech rate differences between the groups the task-activation differences were surprisingly small. For both analyses only some regions previously considered stutter-related were more activated in the PWS group than in the CONT group, and these were also activated during eyes-closed rest (ECR). In the PWS group, stuttering frequency was correlated with cortico-striatal-thalamic circuit activity in both speaking tasks. The neuroimaging findings for the PWS group, relative to the CONT group, appear consistent with neuroanatomic abnormalities being increasingly reported among PWS.     

The effects of differential vowel prolongations on perceptions of speech naturalness

Prolongation of speech sounds is currently used to modify stuttering and enhance fluency. Prolonged speech (PS) (e.g., prolonged vowels, prolongation throughout utterances) is, however, often perceived as unnatural by listeners. This study examined at which durations and in which contexts 52 college students (primary language was American English) perceived PS to be unnatural. Stimuli were limited to controlled variation in prolongation of the vowel in the middle single-syllable word of a carrier phrase (i.e., say word again). The prolongation was effected by digital waveform manipulation within the Kay Elemetrics Computerized Speech Laboratory (CSL). The listeners judged if they strongly agreed, agreed, or disagreed that the phrases sounded natural. Results indicated that the extent of vowel duration (and possibly context) does influence listener's perception of speech naturalness, findings which can be applied to facilitate fluency therapy.

Educational objectives: (1) The reader will learn about and be able to summarize the digital waveform manipulation procedure in the study. (2) The reader will learn about and be able to describe the effects of differential vowel prolongation on listener's perception of speech naturalness. (3) The reader will learn about and evaluate how differential vowel prolongation can be used to enhance fluency.     

Psychometric properties of a revised Spanish 20-item Toronto Alexithymia Scale adaptation in multiple sclerosis patients

There have been a small number of investigations of alexithymia in multiple sclerosis (MS) using the 20-item Toronto Alexithymia Scale (TAS-20). However, the TAS-20 factor structure has not yet been evaluated in a MS patient sample, and earlier Spanish translations of this instrument require some improvement. We aimed to evaluate the factorial validity and reliability of an improved Spanish translation of the TAS-20 (the TAS-20-S). The TAS-20-S was completed by 221 MS patients. Confirmatory factor analysis was used to compare the fit of six different factor models. Internal consistency and retest reliability coefficients were also computed. The correlated three-factor model and the higher-order factor model made up of Difficulty Identifying Feelings, Difficulty Describing Feelings, and Externally Oriented Thinking achieved the best fit. Alpha coefficients ranged between .87 and .67; mean inter-item correlations ranged between .48 and .20; and retest correlations after 6 months ranged between .61 and .52. A high degree of alexithymia was present in 18.1% of the sample. Reliability and the traditional three-factor structure were demonstrated for the TAS-20-S, which can now be recommended for assessing an aspect of emotional processing in MS patients.     

Partial awareness distinguishes between measuring conscious perception and conscious content: Reply to Dienes and Seth

In their comment on Sandberg, Timmermans, Overgaard, and Cleeremans (2010), Dienes and Seth argue that increased sensitivity of the Perceptual Awareness Scale (PAS) is a consequence of the scale being less exclusive rather than more exhaustive. According to Dienes and Seth, this is because PAS may measure some conscious content, though not necessarily relevant conscious content, “If one saw a square but was only aware of seeing a flash of something, then one has not consciously seen a square.” In this reply, we claim that there is a difference between conscious visual experience, which may be partial, and the resulting conscious content, which is conceptual. Whereas PAS measures the first, confidence judgments and post-decision wagering measure the second.     

The time course of anticipatory constraint integration

Several studies have demonstrated that as listeners hear sentences describing events in a scene, their eye movements anticipate upcoming linguistic items predicted by the unfolding relationship between scene and sentence. While this may reflect active prediction based on structural or contextual expectations, the influence of local thematic priming between words has not been fully examined. In Experiment 1, we presented verbs (e.g., arrest) in active (Subject–Verb–Object) sentences with displays containing verb-related patients (e.g., crook) and agents (e.g., policeman). We examined patient and agent fixations following the verb, after the agent role had been filled by another entity, but prior to bottom-up specification of the object. Participants were nearly as likely to fixate agents “anticipatorily” as patients, even though the agent role was already filled. However, the patient advantage suggested simultaneous influences of both local priming and active prediction. In Experiment 2, using passive sentences (Object–Verb–Subject), we found stronger, but still graded influences of role prediction when more time elapsed between verb and target, and more syntactic cues were available. We interpret anticipatory fixations as emerging from constraint-based processes that involve both non-predictive thematic priming and active prediction.     

Testing orofacial abilities of children who stutter: the Movement, Articulation, Mandibular and Sensory awareness (MAMS) assessment procedure

Objective

The purpose of this article is to introduce a new assessment designed to measure the orofacial abilities of children who stutter (CWS), the Movement, Articulation, Mandibular and Sensory Awareness (MAMS) Orofacial Assessment. The new instrument was developed and validated to measure orofacial abilities in a comprehensive manner.

Design

A group of 43 CWS (mean age 13.10 years, S.D. 2.10 years) and a control group of 32 fluent children (mean age 13.4 years, S.D. 2.6 years) were tested with the new tool. It was hypothesized, that (a) the MAMS is a reliable and valid instrument to measure orofacial abilities in CWS, (b) fluent children have better orofacial abilities than CWS and (c) that the therapy outcome of CWS depend on their orofacial abilities.

Results

The MAMS Orofacial Assessment proved to be a valid and reliable instrument to assess orofacial abilities. Compared with their fluent peers, CWS had significantly worse orofacial abilities. CWS with better orofacial abilities had a better prognosis for therapy outcome.

Conclusions

The new instrument is a reliable and valid tool to measure orofacial abilities and MAMS distinguishes CWS and controls. Orofacial abilities are one set of factors that influence therapy outcome for CWS.Educational objectives: The reader will get an overview over of the literature on orofacial abilities in people who stutter and will learn about and be able to (1) describe different characteristics of orofacial abilities, (2) use the MAMS Orofacial Assessment in the diagnostic process for CWS and for research purposes, and (3) interpret the results of the MAMS to use them for therapy planning.     

The Stammering Information Programme: a Delphi study

Purpose

To find out what information children, parents and education staff feel would be important to know to support a child who stutters in the educational environment, in order to develop appropriate resources.

Method

A Delphi study was carried out to seek the opinions of experts about the information to include. A structured six stage process was completed in order to gain consensus within four expert panels: children who stutter (CWS) aged 7-11 (n = 25); young people who stutter aged 12-18 (n = 27); parents of children and young people who stutter aged 2-18 (n = 67); and members of the education workforce (n = 35).

Results

In response to the questions, 538 statements were generated across the four expert panels, categorised and reduced to 276. Of the 154 rating questionnaires sent out, 99 were returned (64.2% response rate). The top 32 statements, which were those most highly rated and with the greatest consensus, were retained to inform the resources.

Conclusions

This study demonstrates the value of including service users when devising materials aimed for the benefit of CWS. The methodology employed ensured that ideas, perceptions and needs were representative of a range of people who experience stuttering from different perspectives. The results indicated that each expert panel had different priorities of what should be included. The resulting resources may therefore be considered to have high content validity and would be predicted to meet the needs of those who require them.Educational Objectives: The reader will be able to (1) define the Delphi Approach (2) discuss the development of a user led resource for raising awareness about stuttering.     

On the (numerical) ranking associated with any finite binary relation

We generalize the concept of a ‘ranking associated with a linear order’ from linear orders to arbitrary finite binary relations. Using the concept of differential of an object in a binary relation as theoretical primitive, we axiomatically introduce several measurement scales, some of which include the generalized ranking as a special case. We provide a computational formula for this generalized ranking, discuss its many elegant properties and offer some illustrating examples.
