Cerebral lateralization in individuals diagnosed as autistic in early childhood

Early infantile autism was found to be associated with an atypical pattern of cerebral lateralization. Based on EEG measures of hemispheric activation during cognitive processing, it was found that 7 of the 10 autistic individuals tested showed a pattern of hemispheric specialization rarely seen in the normal population; namely, a “reversal” in lateralization reflective of a lack of left-hemisphere specialization for linguistic functions. Furthermore, the autistic individuals' pattern of cognitive strengths and weakness is suggestive of a selective impairment of the left cerebral hemisphere.     

“This one’s on me!”: Differential well-being effects of self-centered and recipient-centered motives for spending money on others

Motivation and Emotion - Past research reliably shows that spending money on others (termed prosocial spending) makes people happier than spending money on oneself. The present research tested...

Selective Mutism and Its Relations to Social Anxiety Disorder and Autism Spectrum Disorder

In current classification systems, selective mutism (SM) is included in the broad anxiety disorders category. Indeed, there is abundant evidence showing that anxiety, and social anxiety in particular, is a prominent feature of SM. In this article, we point out that autism spectrum problems in addition to anxiety problems are sometimes also implicated in SM. To build our case, we summarize evidence showing that SM, social anxiety disorder (SAD), and autism spectrum disorder (ASD) are allied clinical conditions and share communalities in the realm of social difficulties. Following this, we address the role of a prototypical class of ASD symptoms, restricted and repetitive behaviors and interests (RRBIs), which are hypothesized to play a special role in the preservation and exacerbation of social difficulties. We then substantiate our point that SM is sometimes more than an anxiety disorder by addressing its special link with ASD in more detail. Finally, we close by noting that the possible involvement of ASD in SM has a number of consequences for clinical practice with regard to its classification, assessment, and treatment of children with SM and highlight a number of directions for future research.

     

Employee Happiness: Why We Should Care

Albert Schweitzer once stated that “success is not the key to happiness, happiness is the key to success.” Despite this widespread belief, employee happiness is often perceived by organizations as an insubstantial topic, irrelevant to bottom-line outcomes. Equally as problematic, past investigations have primarily utilized other positive emotion variables as a proxy for happiness, thus convoluting the relationships between happiness and work outcomes. As such, taking a scientist-practitioner approach, the present study sought to address the need to: (a) directly measure employees’ happiness, (b) link employee happiness to outcomes of organizational interest, and (c) assess the impact that organizational psychosocial factors have in decreasing employee happiness levels. Therefore, by measuring employee happiness, job demands, and organizational outcomes through a two-wave full panel design, the present study provided evidence for employee happiness’s ability to significantly mediate the relationship between job demands and organizational outcomes. Explicitly, a high level of job demands decreased employee happiness, which subsequently decreased employees’ organizational commitment, task performance, and contextual performance, while increasing turnover intentions and counterproductive work behaviors. These results carry significant theoretical and practical implications. Future QOL (Quality of Life) and organizational research would benefit from building on the present findings and establishing a nomological net of employee happiness. Additionally, practitioners have the opportunity to utilize this evidence to demonstrate the impact that employee happiness has on organizationally-relevant outcomes and the role that organizations can have in fostering employee happiness.

     

Temperamental Factors in the Execution of Interrupted Editing Tasks

The question investigated in this study is how the temperament traits of strength of excitation (SE), strength of inhibition (SI), and mobility (MO) affect behaviour during the execution of computer tasks and tasks interrupting them. Several hypotheses, partly derived from the regulative theory of temperament, were tested in an experiment in which the natural environment and the types of task commonly performed by secretaries were simulated. The sample consisted of 39 female secretaries (21–64 years old). It was found that individuals high on SE and MO needed less time to resume tasks after an interruption than individuals low on these temperament traits. Interruptions similar to the main task resulted in longer resumption times for low-SE individuals. MO was negatively related to the time needed to perform the main task. A model describing the relationship between the frequency of switches between tasks and the speed of task performance in low-MO and high-MO individuals is presented.     

EVidence for dorsolateral and orbital prefrontal cortical involvement in the expression of aggressive behavior

Numerous studies have implicated the role of the prefrontal cortex in the expression of aggressive behavior. However, the nature of this relationship remains poorly understood. As such, the purpose of this article is to review both the animal and human literature pertaining to prefrontal cortical functioning and aggression in an attempt to help clarify this relationship. Particular attention is paid to differentiating the functions of the dorsolateral and the orbital regions of the prefrontal cortex in the expression of aggression. Evidence was garnered from four different types of studies: 1) those examining aggressive behavior in animals following ablations to the prefrontal cortex; 2) those examining aggressive behavior in humans following surgical and accidental lesions to the prefrontal cortex; 3) those examining prefrontal cortical functioning in individuals with psychiatric disorders characterized by aggression; and 4) those relating prefrontal cortical functioning to human aggressive behavior in laboratory situations. The general conclusion of this article is that the dorsolateral region of the prefrontal cortex is more likely to be involved in the expression of physical aggression whereas the orbital region is more likely to be involved in the expression of what is termed herein “disinhibited-nonaggressive” behavior. © 1995 Wiley-Liss, Inc.
