Mutism in an Adult Following Hypertensive Cerebellar Hemorrhage: Nosological Discussion and Illustrative Case

Mutism after cerebellar injury has been associated with tumors, hemorrhage, and surgery of midline cerebellar structures. Literature review identified 54 cases, primarily in children after surgical splitting of the inferior vermis. We present a 47-year-old who developed transient mutism after cerebellar hemorrhage. This represents the first report of transient mutism in an adult with neither tumor nor brainstem infarction and documents the importance of cerebellar structures for initiation and production of speech in adulthood. This case further differs from those previous because of the long mute period and the subsequent return of continued ataxic and dysarthric speech.     

Contrasting Grammatical and Lexical Determiners

This paper investigates the difference between the production of grammatical determiners and lexical determiners in the production of adjective-noun phrases (NPs) in Danish. Models of sentence processing (Garrett in Psychology of learning and motivation, Academic press, New York, pp 133–177, 1975; Bock in J Mem Lang 26(2):119–137, 1987) suggest that the phonological encoding stage of grammatical items can only be specified once lexical items have been phonologically encoded. In their usage-based linguistic theory of the grammar-lexicon distinction, Boye and Harder (Lang 88(1):1–44, 2012) propose that this later encoding of grammatical elements is motivated by two specific features of grammatical elements. The first feature, dependence, is that grammatical items (morphemes, words, constructions) cannot be produced in isolation, but are always dependent on a lexical host item. This feature entails a more complex processing which might lead to longer reaction times when comparing the production of NPs with a grammatical determiner to a lexical one. Additionally, a more complex processing might lead to a lower accuracy rate for the grammatical condition relative to the lexical one. The second feature, low prominence, is that grammatical items code background information and therefore cannot convey the main point of a linguistic message. Less focus on grammatical elements might lead to a lower accuracy rate for the production of grammatical elements relative to lexical ones. Those predictions were tested in a task comparing the production of Danish grammatical determiners (indefinite articles) with the production of lexical ones (numerals, which are homonymous with the articles except for a stress difference) in similar contexts. Group-based analyses were performed in order to take inter-individual differences into account. The results show that the two features as proposed by Boye and Harder (2012) are only revealed for the fastest speakers group but not the slower ones.     

Selection history: How reward modulates selectivity of visual attention

Visual attention enables us to selectively prioritize or suppress information in the environment. Prominent models concerned with the control of visual attention differentiate between goal-directed, top-down and stimulus-driven, bottom-up control, with the former determined by current selection goals and the latter determined by physical salience. In the current review, we discuss recent studies that demonstrate that attentional selection does not need to be the result of top-down or bottom-up processing but, instead, is often driven by lingering biases due to the “history” of former attention deployments. This review mainly focuses on reward-based history effects; yet other types of history effects such as (intertrial) priming, statistical learning and affective conditioning are also discussed. We argue that evidence from behavioral, eye-movement and neuroimaging studies supports the idea that selection history modulates the topographical landscape of spatial “priority” maps, such that attention is biased toward locations having the highest activation on this map.     

How Abusive Supervision Affects Workplace Deviance: A Moderated-Mediation Examination of Aggressiveness and Work-Related Negative Affect

Purpose

This research examines the linking mechanisms and conditional processes underlying the abusive supervision and workplace deviance relationship. Based primarily on Affective Events Theory, it was hypothesized that work-related negative affect would mediate the relationship between abusive supervision and workplace deviance, and that this indirect effect would be moderated by employee-based and organization-based aggressiveness.

Design/Methodology/Approach

Two independent studies were conducted, including diverse working samples and multi-wave data, to test these relationships through mediation and moderated-mediation bootstrapping procedures.

Findings

Both studies suggest that work-related negative affect mediates the abusive supervision and workplace deviance relationship. Mixed findings were found for the moderating effect of employee-based and organization-based aggressiveness. In Study 1 higher levels of employee-based aggressive beliefs and attitudes increased the magnitude of the indirect effect; however, in Study 2 when taking into account organization-based aggressive norms only the facet of social discounting bias increased this relationship. In Study 2 higher levels of organization-based aggressive norms also increased the magnitude of the indirect effect for supervisor-directed deviance.

Implications

Theoretical and practical implications of these findings suggest a movement toward an emotion-centered process-based theory of workplace deviance.

Originality/Value

A central question in organizational behavior research revolves around what drives employees to engage in various workplace behaviors. Replicating research that suggests abusive supervision is an important factor in this question, this research helps illuminate the processes underlying this perception-to-behavior link, as well as the boundary conditions of these processes.

     

Challenge and threat emotions as antecedents of recovery experiences: findings from a diary study with blue-collar workers

The aim of this study was (1) to investigate whether threat (e.g., anxiety, fear) and challenge (e.g., confidence, excitement) emotions that employees experience before work while thinking about the upcoming workday predict their recovery experiences (i.e., psychological detachment, relaxation, mastery, and control) after work and (2) to explore the moderating role of job control on the effect of threat and challenge emotions on recovery experiences. For two to four weeks, 57 blue-collar workers at an airport’s hub station completed a diary. Multilevel analyses (N = 1104) reveal that threat emotions in the morning decrease psychological detachment and relaxation after work. Job control buffers this negative effect. Furthermore, challenge emotions in the morning boost mastery after work. Next, when employees have low job control, challenge emotions also boost the recovery experience control. Practical implications and the need for future studies to examine more fine-grained mechanisms for better understanding how threat and challenge emotions experienced before starting work affect recovery experiences after work are discussed.     

Valuing Happiness is Not a Good Way of Pursuing Happiness,but Prioritizing Positivity is: A Replication Study

Numerous studies confirm the merits of positive psychology. However, an emerging literature brings nuances, with one particular question concerning the impact of pursuing happiness: is this always positive? Some data suggest that an excessive level of valuing happiness may partly diminish the happiness felt, but that prioritizing positivity may increase subjective well-being. The aim of the present study was to replicate these findings. Participants (N = 683, 75% female) completed the prioritizing positivity scale (PPS) and the valuing happiness scale (VHS), as well as four well-being scales: the subjective happiness scale (SHS), the satisfaction with life scale (SWLS), the psychological well-being scales (PWB) and the center for epidemiological studies – depression (CES-D). Regression analyses showed that prioritizing positivity was positively associated with subjective happiness, life satisfaction and psychological well-being, but that it was negatively linked to depression. Opposite results partly emerged for valuing happiness. This cross-sectional study confirms that the way people pursue happiness, by prioritizing positivity or valuing it, may promote or partly hinder well-being.     

Infant visual habituation and parental psychological distress

Research is equivocal concerning the relationship between parental psychological distress and infant cognitive functioning. Four potential limitations of the literature are addressed: reliance on mothers' but not fathers' psychological distress, use of categorical measures of psychological distress, use of standardized measures of infant cognitive functioning, and failure to take into account potential gender differences. Ninety‐nine twin pairs and both their mothers and fathers were assessed. Infants cognitive functioning was assessed using an infant‐controlled habituation–recovery–dishabituation task. Maternal and paternal psychological distress was assessed using the Symptom Check List‐90‐Revised. No gender differences were obtained for infant visual information‐processing abilities or parental psychological distress. Maternal and paternal psychological distress was related to female visual encoding abilities only. It was concluded that parental psychological distress might degrade parent–infant interactions. Characteristics of girls when faced with parents exhibiting psychiatric difficulties may exacerbate difficulties of parent–infant interactions, thereby hindering the full development of cognitive abilities involved in the process of habituation. A need exists to examine the relationship between parental psychological distress and infant visual attention separately for girls and boys. ©2001 Michigan Association for Infant Mental Health.
