Having an abusive boss not only causes problems at work but can lead to strained relationships at home, according to a Baylor University study published online in journal, Personnel Psychology. The study found that stress and tension caused by an abusive boss have an impact on the employee's partner, which affects the marital relationship and subsequently the employee's entire family. The study also found that more children at home meant greater family satisfaction for the employee, and the longer the partner's relationship, the less impact the abusive boss had on the family.

"These findings have important implications for organizations and their managers. The evidence highlights the need for organizations to send an unequivocal message to those in supervisory positions that these hostile and harmful behaviors will not be tolerated," said Dawn Carlson, Ph.D., study author, professor of management and H. R. Gibson Chair of Organizational Development at the Hankamer School of Business at Baylor University, Waco. A supervisor's abuse may include tantrums, rudeness, public criticism and inconsiderate action. "It may be that as supervisor abuse heightens tension in the relationship, the employee is less motivated or able to engage in positive interactions with the partner and other family members," said Merideth Ferguson, PH.D., study co-author and assistant professor of management and entrepreneurship at Baylor. Organizations should encourage subordinates to seek support through their organization's employee assistance program or other resources (e.g., counseling, stress management) so that the employee can identify tactics or mechanisms for buffering the effect of abuse on the family, according to the study.

The study included 280 full-time employees and their partners. Fifty-seven percent of the employees were male with an average of five years in their current job; 75 percent had children living with them. The average age for the employee and the partner was 36 years. The average length of their relationship was 10 years. Of the respondents, 46 percent supervised other employees in the workplace, 47 percent worked in a public organization, 40 percent worked in a private organization, nine percent worked for a non-profit organization and five percent were self-employed. Of the partner group, 43 percent were male with 78 percent of these individuals employed.

Workers filled out an online survey. When their portion of the survey was complete, their partner completed a separate survey that was linked back to the workers'. The partner entered a coordinating identification number to complete his/her portion of the survey. The combined responses from the initial contact and the partner constituted one complete response in the study database. Questions in the employee survey included; "How often does your supervisor use the following behaviors with you?" with example items being "Tells me my thoughts or feelings are stupid," "Expresses anger at me when he/she is mad for another reason," "Puts me down in front of others," and "Tells me I'm incompetent."

Questions in the partner survey included; "During the past month, how often did you . . ." feel irritated or resentful about things your (husband/wife/partner) did or didn't do" and "feel tense from fighting, arguing or disagreeing with your (husband/wife/partner)." "Employers must take steps to prevent or stop the abuse and also to provide opportunities for subordinates to effectively manage the fallout of abuse and keep it from affecting their families. Abusive supervision is a workplace reality and this research expands our understanding of how this stressor plays out in the employee's life beyond the workplace," Carlson said.

As we get older, our cognitive abilities change, improving when we're younger and declining as we age. Scientists posit a hierarchical structure within which these abilities are organized. There's the "lowest" level -- measured by specific tests, such as story memory or word memory; the second level, which groups various skills involved in a category of cognitive ability, such as memory, perceptual speed, or reasoning; and finally, the "general," or G, factor, a sort of statistical aggregate of all the thinking abilities.

What happens to this structure as we age? That was the question Timothy A. Salthouse, Brown-Forman professor of psychology at the University of Virginia, investigated in a new study appearing in an upcoming issue of Psychological Science, a journal published by the Association for Psychological Science. His findings advance psychologists' understanding of the complexities of the aging brain.

"There are three hypotheses about how this works," says Salthouse. "One is that abilities become more strongly integrated with one another as we age." That theory suggests the general factor influences cognitive aging the most. The second -- based on the idea that connectivity among different brain regions lessens with age -- "is almost the opposite: that the changes in cognitive abilities become more rather than less independent with age." The third was Salthouse's hypothesis: The structure remains constant throughout the aging process.

Using a sample of 1,490 healthy adults ages 18 to 89, Salthouse performed analyses of the scores on 16 tests of five cognitive abilities -- vocabulary, reasoning, spatial relations, memory, and perceptual speed. The primary analyses were on the changes in the test scores across an interval of about two and a half years.

The findings confirmed Salthouse's hunch: "The effects of aging on memory, on reasoning, on spatial relations, and so on are not necessarily constant. But the structure within which these changes are occurring does not seem to change as a function of age." In normal, healthy people, "the direction and magnitude of change may be different" when we're 18 or 88, he says. "But it appears that the qualitative nature of cognitive change remains the same throughout adulthood."

The study could inform other research investigating "what allows some people to age more gracefully than others," says Salthouse. That is, do people who stay mentally sharper maintain their ability structures better than those who become more forgetful or less agile at reasoning? And in the future, applying what we know about the structures of change could enhance "interventions that we think will improve cognitive functioning" at any age or stage of life.

Distinct neural pathways are important for different aspects of language processing, researchers have discovered, studying patients with language impairments caused by neurodegenerative diseases

While it has long been recognized that certain areas in the brain's left hemisphere enable us to understand and produce language, scientists are still figuring out exactly how those areas divvy up the highly complex processes necessary to comprehend and produce language. Advances in brain imaging made within the last 10 years have revealed that highly complex cognitive tasks such as language processing rely not only on particular regions of the cerebral cortex, but also on the white matter fiber pathways that connect them. "With this new technology, scientists started to realize that in the language network, there are a lot more connecting pathways than we originally thought," said Stephen Wilson, who recently joined the University of Arizona's department of speech, language and hearing sciences as an assistant professor. "They are likely to have different functions because the brain is not just a homogeneous conglomerate of cells, but there hasn't been a lot of evidence as to what kind of information is carried on the different pathways."

Working in collaboration with his colleagues at the UA, the department of neurology at the University of California, San Francisco and the Scientific Institute and University Hospital San Raffaele in Milan, Italy, Wilson discovered that not only are the connecting pathways important for language processing, but they specialize in different tasks. Two brain areas called Broca's region and Wernicke's region serve as the main computing hubs underlying language processing, with dense bundles of nerve fibers linking the two, much like fiber optic cables connecting computer servers. But while it was known that Broca's and Wernicke's region are connected by upper and a lower white matter pathways, most research had focused on the nerve cells clustered inside the two language-processing regions themselves.

Working with patients suffering from language impairments because of a variety of neurodegenerative diseases, Wilsons' team used brain imaging and language tests to disentangle the roles played by the two pathways. Their findings are published in a recent issue of the scientific journal Neuron. "If you have damage to the lower pathway, you have damage to the lexicon and semantics," Wilson said. "You forget the name of things, you forget the meaning of words. But surprisingly, you're extremely good at constructing sentences. With damage to the upper pathway, the opposite is true; patients name things quite well, they know the words, they can understand them, they can remember them, but when it comes to figuring out the meaning of a complex sentence, they are going to fail."

The study marks the first time it has been shown that upper and lower tracts play distinct functional roles in language processing, the authors write. Only the upper pathway plays a critical role in syntactic processing.

Wilson collected the data while he was a postdoctoral fellow working with patients with neurodegenerative diseases of varying severity, recruited through the Memory and Aging Center at UCSF. The study included 15 men and 12 women around the age of 66. Unlike many other studies investigating acquired language disorders, which are called aphasias and usually caused by damage to the brain, Wilson's team had a unique opportunity to study patients with very specific and variable degrees of brain damage. "Most aphasias are caused by strokes, and most of the strokes that affect language regions probably would affect both pathways," Wilson said. "In contrast, the patients with progressive aphasias who we worked with had very rare and very specific neurodegenerative diseases that selectively target different brain regions, allowing us to tease apart the contributions of the two pathways."

To find out which of the two nerve fiber bundles does what in language processing, the team combined magnetic resonance brain imaging technology to visualize damaged areas and language assessment tasks testing the participants' ability to comprehend and produce sentences. "We would give the study participants a brief scenario and ask them to complete it with what comes naturally," Wilson said. "For example, if I said to you, 'A man was walking along the railway tracks. He didn't hear the train coming. What happened to the man?' Usually, you would say, 'He was hit by the train,' or something along those lines. But a patient with damage to the upper pathway might say something like 'train, man, hit.' We found that the lower pathway has a completely different function, which is in the meaning of single words."

To test for comprehension of the meaning of a sentence, the researchers presented the patient with a sentence like, "The girl who is pushing the boy is green," and then ask which of the two pictures depicted that scenario accurately. "One picture would show a green girl pushing a boy, and the other would show a girl pushing a green boy," Wilson said. "The colors will be the same, the agents will be the same, and the action is the same. The only difference is, which actor does the color apply to? Those who have only lower pathway damage do really well on this, which shows that damage to that pathway doesn't interfere with your ability to use the little function words or the functional endings on words to figure out the relationships between the words in a sentence."

Wilson said that most previous studies linking neurodegeneration of specific regions with cognitive deficits have focused on damage to gray matter, rather than the white matter that connects regions to one another. "Our study shows that the deficits in the ability to process sentences are above and beyond anything that could be explained by gray matter loss alone," Wilson added. "It is the first study to show that damage to one major pathway more than then other major pathway is associated with a specific deficit in one aspect of language."

Investigation claims dozens of social-psychology papers contain faked data.
