Zap! Magnetic tricks on conscious and unconscious vision

Blindsight, the remarkable capability to react to unseen visual stimuli, has thus far only been demonstrated in patients and monkeys with a lesion to primary visual cortex. A recent study by Boyer, Harrison and Ro demonstrates blindsight in normal human observers, using TMS to block visual processing. Combined with other work, this opens new vistas towards understanding mechanisms of conscious and unconscious vision.     

Caregiving decision making by older mothers and adult children: process and expected outcome

Dyadic caregiving decision making was studied in 30 mother-son and 29 mother-daughter pairs (mother's age=65-94 years) who responded to a vignette depicting a caregiving decision situation. The observed decision-making process of mother-child pairs was largely naturalistic, with few alternatives proposed and quick convergence to a decision followed by a postdecision justification; a degree of more rational decision making was seen in some pairs. Among significant findings, adult children, especially sons, dominated the decision process, doing more talking and introducing more alternatives than did their mothers, who played a more subordinate role. Mother-son pairs expected more negative outcomes and greater regrets regarding their decisions than mother-daughter pairs. Closeness of the parent-child relationship influenced the decision-making process, expected outcomes, and regrets.     

Neural correlates of morphological decomposition in a morphologically rich language: an fMRI study

By employing visual lexical decision and functional MRI, we studied the neural correlates of morphological decomposition in a highly inflected language (Finnish) where most inflected noun forms elicit a consistent processing cost during word recognition. This behavioral effect could reflect suffix stripping at the visual word form level and/or subsequent meaning integration at the semantic-syntactic level. The first alternative predicts increased activation for inflected vs. monomorphemic words in the left occipitotemporal cortex while the second alternative predicts left inferior frontal gyrus and/or left posterior temporal activation increases. The results show significant activation effects in the latter areas. This provides support for the second alternative, i.e., that the morphological processing cost stems from the semantic-syntactic level.     

MMPI--2 Code-Type Congruence of Injured Workers

In this study, the authors examined the stability of Minnesota Multiphasic Personality Inventory--2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) code types in a sample of 94 injured workers with a mean test-retest interval of 21.3 months (SD = 14.1). Congruence rates for undefined code types were 34% for high-point codes, 22% for 2-point codes, and 22% for 3-point codes. The data provide tentative evidence suggesting that defined code types are more stable than undefined code types. Cohen's kappa, a statistic that controls for chance agreement, was calculated for each clinical scale for both 2-point and 3-point code types. Only 2 of the 20 kappa coefficients were not significant at the p = .05 level.

Psychiatry Residents' Attitudes on Ethics and Professionalism: Multisite Survey Results

Recent studies show that psychiatry residents express a relatively greater need for ethics curricula than their colleagues in other specialties. Such studies have been limited in their generalizability because they were conducted at one site. This study of 151 psychiatry residents at seven U.S. psychiatry programs aims to address that limitation. Residents were surveyed on issues pertaining to ethics and professionalism education. Participants were found to support such curricula during training and to value its relevance to the practice of psychiatry. Gender differences and the influence of the “hidden curriculum” on such results merit further study.
