Memory deficits before and after temporal lobectomy: Effect of laterality and age of onset

Laterality and age of onset effects on semantic and figural memory were evaluated in 30 right-handed, left speech dominant (amobarbital test) patients with epilepsy before and after temporal lobectomy. There were no effects of focus on WAIS-R IQ scores. Early onset (less than or equal to 5 years) was associated with lower IQ and memory (WMS). Left Temporal (LT) patients showed worse semantic than figural memory preoperatively. Unexpectedly, early onset LT had marked postoperative decline of figural memory, whereas late onset LT patients showed the previously reported worsening of semantic memory. Right Temporal (RT) lobectomy patients, in contrast, improved in both semantic and figural memory regardless of age of onset. A "crowding effect" was suggested by the decline in figural memory following surgery in the early onset LT patients who remained stable or improved in semantic memory. Results indicate the need to incorporate age of onset of seizures into laterality models of memory function following unilateral temporal-hippocampal resection.     

Ethical considerations for neuropsychologists as functional magnetic imagers

This discussion highlights ethical and practical issues potential neuropsychologist-imagers should consider in conducting functional magnetic resonance imaging (fMRI). While fMRI is not currently approved for clinical use, research is ongoing which has implications for clinical practice, from refining brain-behavior relationships, to assisting with diagnosis and treatment decisions. To protect the welfare of cognitively impaired populations requires special care with respect to MR risks and informed consent. Competent functional imaging requires an understanding of the strengths, limitations, and appropriate domain of applications of the measure.     

Approaches to Cognitive Remediation of Neuropsychological Deficits in Schizophrenia: A Review and Meta-Analysis

A review and critique of the literature pertaining to the use of cognitive remediation techniques in patients with schizophrenia is presented. The review is organized into three sections, according to the neuropsychological deficit targeted for remediation: 1) executive-function, 2) attention, and 3) memory. With regards to executive-function, despite an initial report suggesting that Wisconsin Card Sorting Test performance cannot be remediated, subsequent studies suggest that performance can be improved on a variety of dependent measures including perseverative errors, categories achieved, and conceptual level responses. These observations were confirmed by a meta-analytic investigation that revealed large mean effects sizes (d ₊ = 0.96) for these studies. Effect sizes were homogenous across discrepant remediation strategies and dependent measures. With regards to attention, serial scanning can be improved with instruction and reinforcement, whereas there is mixed evidence suggesting that practice-based attention drills can improve performance on measures of sustained attention in schizophrenia. With regards to memory, relatively simple semantic and affective elaborate encoding strategies elevates verbal list-learning memory in patients with schizophrenia to levels consistent with controls. A similar encoding procedure, combined with vigilance training, produces substantial improvement in social cue recognition. Avenues for future research are discussed.     

Smiling in a Job Interview: When Less Is More

Two studies examined the effect of applicants’ smiling on hireability. In a pre-test study, participants were asked to rate the expected behavior for four types of applicants. Newspaper reporter applicants were expected to be more serious than applicants for other jobs. In Study 1, participants were randomly assigned to be an applicant or interviewer for a newspaper reporting job. Smiling was negatively related to hiring, and smiling mediated the relation between applicants’ motivation to make a good impression and hiring. Hiring was maximized when applicants smiled less in the middle of the interview relative to the start and end. In Study 2, participants watched Study 1 clips and were randomly assigned to believe the applicants were applying to one of four jobs. Participants rated more suitability when applicants smiled less, especially for jobs associated with a serious demeanor. This research shows that job type is an important moderator of the impact of smiling on hiring.     

Breast Cancer Risk Perceptions among Relatives of Women with Uninformative Negative <Emphasis Type="Italic">BRCA1/2</Emphasis> Test Results: The Moderating Effect of the Amount of Shared Information

The most common result of BRCA1/2 mutation testing when performed in a family without a previously identified mutation is an uninformative negative test result. Women in these families may have an increased risk for breast cancer because of mutations in non-BRCA breast cancer predisposition genes, including moderate- or low-risk genes, or shared environmental factors. Genetic counselors often encourage counselees to share information with family members, however it is unclear how much information counselees share and the impact that shared information may have on accuracy of risk perception in family members. We evaluated 85 sisters and daughters of women who received uninformative negative BRCA1/2 results. We measured accuracy of risk perception using a latent variable model where accuracy was represented as the correlation between perceived risk (indicators = verbal and quantitative measures) and calculated risk (indicators = Claus and BRCAPRO). Participants who reported more information was shared with them by their sister or mother about her genetic counseling session had greater accuracy of risk perception (0.707, p?=?0.000) than those who reported little information was shared (0.326, p?=?0.003). However, counselees shared very little information; nearly 20 % of family members reported their sister or mother shared nothing with them about her genetic counseling. Family members were generally not aware of the existence of a genetic counseling summary letter. Our findings underscore the need for effective strategies that facilitate counselees to share information about their genetic counseling sessions. Such communication may help their relatives better understand their cancer risks and enhance risk appropriate cancer prevention.     

The unconscious side of Facebook: Do online social network profiles leak cues to users’ implicit motive dispositions?

In this study we investigated the links between motive dispositions and online social network (OSN) profile content. We assessed the achievement, affiliation and power motives via self- and peer-report. In addition, we used a projective test and two novel, affect based measures (involving affect ratings and EMG recordings) to assess implicit motives in the three content domains. Two observers independently coded motive-specific OSN content. Results showed that self-reports were linked to OSN content for the power domain. Peer-reports and measures of implicit motives were positively linked to OSN content across motive domains. In most cases, measures of implicit motives were still linked to OSN content after adjusting for self- and peer-reports. These results indicate that OSN profiles may leak cues to users’ implicit motives, which neither users themselves nor their peers are aware of. Implications for motive theory, motive assessment, and targeted online advertising will be discussed.     

Wenn Psychotherapie schadet …

Background

The examination of the negative and harmful effects of psychotherapy has recently moved into the focus of psychotherapy research. The investigation described in the following article specifically analyzes for the first time the contents of complaints by psychotherapy patients and presents a practical category system for classification of the negative effects of psychotherapeutic treatment.

Samples and method

A total of 67 cases of complaints submitted to the Ethics Association (reg. co). Ethics in Psychotherapy during the time period from 18.02.2008 to 27.12.2010 were analyzed with respect to the content in the sense of an inductive categorization and quantitative evaluation.

Results

From the available patient complaints a reliable category system could be elucidated. The violation of therapeutic base variables and violations of sexual limitations were the most common cause of complaints against male therapists whereas for female therapists accusations of violation of medical confidentiality and documentation duty were significantly higher.

Conclusions

The results of this study allow formulation of research recommendations for extended investigation of the negative effects of psychotherapy and reveal options for the development of a targeted risk management.
