WORKPLACE SOCIAL SUPPORT AND WORK-FAMILY CONFLICT: A META-ANALYSIS CLARIFYING THE INFLUENCE OF GENERAL AND WORK-FAMILY-SPECIFIC SUPERVISOR AND ORGANIZATIONAL SUPPORT

This article uses meta-analysis to develop a model integrating research on relationships between employee perceptions of general and work-family-specific supervisor and organizational support and work-family conflict. Drawing on 115 samples from 85 studies comprising 72,507 employees, we compared the relative influence of 4 types of workplace social support to work-family conflict: perceived organizational support (POS); supervisor support; perceived organizational work-family support, also known as family-supportive organizational perceptions (FSOP); and supervisor work-family support. Results show work-family-specific constructs of supervisor support and organization support are more strongly related to work-family conflict than general supervisor support and organization support, respectively. We then test a mediation model assessing the effects of all measures at once and show positive perceptions of general and work-family-specific supervisor indirectly relate to work-family conflict via organizational work-family support. These results demonstrate that work-family-specific support plays a central role in individuals' work-family conflict experiences.     

Subtyping stuttering I: a review

A reliable and practical subtype system of stuttering should enhance all related scientific work concerned with this disorder. Although a fair number of classification systems have been offered, to date, none has received wide recognition or has been routinely applied in research or clinical spheres. Whereas progress has been made in understanding and treating the disorder, for the most part stuttering continues to be viewed and addressed as a unitary problem. The objectives of the current article are to (a) highlight the motivation for identifying sub-types of stuttering, (b) outline the issues involved in researching subtypes, and (c) address the question of whether or not subtyping is plausible for this disorder. Toward these ends, a broad-based review of past concepts regarding subtypes of stuttering and stutterers is presented according to seven categories that reflect the various authors' conceptual or experimental approaches. Selected studies for each category are also presented to illustrate the research problems and challenges. It is concluded that islands of progress can be identified in subtype research, particularly in studies of children. It is recommended that future studies include multiple factors or domains in the data collection process, especially with young children during the formative years of the disorder, when substantial overlap in the development of several speech/language domains occurs. EDUCATIONAL OBJECTIVES: (a) Readers will be able to describe the theory and research concerning the numerous attempts to subtype stuttering, particularly during the past 50 years; (b) Readers will be able to explain the general issues that need to be resolved in order to identify subtypes as well as current and future research strategies aimed at achieving these goals.     

Computational Interpretations of the Gricean Maxims in the Generation of Referring Expressions

We examine the problem of generating definite noun phrases that are appropriate referring expressions; that is, noun phrases that (a) successfully identify the intended referent to the hearer whilst (b) not conveying to him or her any false conversational implicatures (Grice, 1975). We review several possible computational interpretations of the conversational implicature maxims, with different computational costs, and argue that the simplest may be the best, because it seems to be closest to what human speakers do. We describe our recommended algorithm in detail, along with a specification of the resources a host system must provide in order to make use of the algorithm, and an implementation used in the natural language generation component of the IDAS system.     

Positivity ratio of flourishing individuals: Examining the moderation effects of methodological variations and chronological age

We tested the relationship between flourishing and positivity ratio while accounting for different measures of affect and rating scale formats. We further examined age-related differences in positivity ratio. Studies 1 and 2 showed that positivity ratio is affected by the measure used, but not by the rating scale format. Study 3 further showed that positivity ratio is higher among older adults. The above pattern of methodological variations was replicated in Study 4 with daily ratings of emotions and in Study 5 where emotions were rated on an extended scale. Study 5 also replicated the aforementioned age effect. Together these studies suggest that positivity ratio is moderated by methodological variants and individual differences, such as chronological age. Future studies should account for these possible moderation effects when exploring the positivity ratio and its relationship to flourishing.     

The Effect of Training with Music on Happiness Recognition in Social Anxiety Disorder

The process of emotion recognition is thought to be negatively biased in social anxiety disorder (SAD). Ways to change this bias are needed. Forty one individuals afflicted with moderate SAD and 39 healthy controls were recruited to participate in this study. All subjects performed a vocal improvisation recognition task and half of them underwent training in happiness recognition in musical improvisations. The four groups (trained SAD, untrained SAD, trained controls and untrained controls) were then compared in terms of the extent of precise identification of one of five basic emotions (happiness, fear, anger, sadness and surprise) in spoken language. Subjects with SAD demonstrated less accurate identification of happiness in spoken language as compared to the healthy controls. However, subjects with SAD trained to recognize happiness demonstrated an improved ability to identify happiness in spoken language (in a female’s voice), similarly to that of the healthy controls. Our findings demonstrate that a brief training in happiness recognition improves the ability of individuals with SAD to recognize happiness in spoken language. Additional studies are needed to support and refine our intervention and to examine its impact on individuals with SAD over longer periods of time.     

Reevaluating the potency of the memory conformity effect

Witnesses sometimes report event details that are acquired solely from another witness. We reevaluated the potency of this memory conformity effect. After viewing a crime video, some participants learned about nonwitnessed details via discussion (dyad group), reading another participant’s report (read group), or watching another version of the video (both-video group). In Experiment 1, these participants often reported nonwitnessed details, but on a source-judgment test most details were attributed primarily to the actual source rather than to the video. In addition, the dyad group was not more likely than the read or both-video groups to report nonwitnessed details. Participants in Experiment 2 were explicitly discouraged from providing details that were remembered from the secondary source only. These postwarning instructions substantially reduced the memory conformity effect, and a dyad group was not more likely than a read group to report nonwitnessed details. Encouraging source monitoring at test can reduce the negative consequences of co-witness collaboration.     

Disfluent speech associated with brain damage

The frequency and type of disfluencies in the spontaneous speech of 15 people with Broca's aphasia and right hemiplegia was studied. Two aged-matched control groups (15 nonaphasic stroke patients with left hemiplegia and 15 normals) were also studied. The frequency of disfluencies in the speech of aphasics was three times greater than that in the speech of either control group. However, most of the disfluencies uttered by aphasics were of the types commonly found in speech of normals.
