Schizophrenic tendencies and memory deficits in normals

The report tests the hypothesis that normals who exhibit schizophrenic tendencies are likely to show verbal-memory deficits of the types observed in schizophrenics. Thirty-four middle-aged men were tested using the MMPI 2–7–8 schizophrenic-tendency scales, the Sorting Consistency Task and the Physical Anhedonia Scale. The dependent variables were four memory tests selected on the basis of their known discriminating power and their relevance. The results showed the Schizophrenia (8) and Psychasthenia (7) scales of MMPI, and the Sorting Consistency Task effectively detected memory deficits in normals. When partialling out intelligence, as a measure of general current cognitive functioning, it appeared that one of the deficits reflecting encoding difficulty disappeared. This suggests that normal ‘high-risk’ subjects for schizophrenia show a ‘generalized deficit’, which affects memory in addition to a ‘differential deficit’ in retention. Though tentative, the results can be taken as an indication that ‘high-risk’ subjects indeed show memory deficits and that detecting these deficits requires relatively sensitive tools.     

Characteristics of Completed Suicides: Implications of Differences Among Methods

Approximately 30% of suicides in New York City are the result of jumping from a height. After describing jumping suicides and jumping sites, we used polychotomous logistic regression to compare the characteristics of suicides by jumping to those of individuals committing suicide by hanging, ingestion, or shooting. Method used was significantly associated with sociodemographics, occupation, and mental health status, even after adjustment for individual access to the means of committing suicide. Our finding of an independent association between personal characteristics and method used provides strong evidence for the hypothesis that controlling access to an agent of suicide can influence overall suicide rates, at least in the short term. Study results support the introduction of preventive programs to control access to commonly employed agents of suicide.

Context and alcohol consumption behaviors affect inhibitory control

Contrasting the traditional focus on alcohol‐related visual images, this study examined the impact of both alcohol‐related auditory cues and visual stimuli on inhibitory control (IC). Fifty‐eight participants completed a Go/No‐Go Task, with alcohol‐related and neutral visual stimuli presented with or without short or continuous auditory bar cues. Participants performed worse when presented with alcohol‐related images and auditory cues. Problematic alcohol consumption and higher effortful control (EC) were associated with better IC performance for alcohol images. It is postulated that those with higher EC may be better able to ignore alcohol‐related stimuli, while those with problematic alcohol consumption are unconsciously less attuned to these. This runs contrary to current dogma and highlights the importance of examining both auditory and visual stimuli when investigating IC.     

Balint groups in undergraduate medical education: a systematic review

Objective: Though Balint groups feature increasingly in UK medical school curricula, there is no evidence-based consensus on what undergraduates might gain from participation, and how this might happen. To address this, we systematically reviewed primary research studies involving medical student Balint groups and their relationship with patient-centredness, using narrative synthesis. Data sources: Four major databases were searched from origin until 9 September 2016. The Journal of the Balint Society was hand-searched from 1971 until 9 September 2016. Study selection: English language studies reporting quantitative and/or qualitative methods examining Balint groups in medical students vs. other/no comparator. Results: Eight studies were included. Quantitative findings report statistically significant improvements to student’s empathy and intellectual interest following group participation vs. control (p = 0.03, p = 0.046, respectively). Discussion content was similar across high-income countries. There was considerable heterogeneity when students rated the efficacy of groups. All evidence had high or unclear risk of bias, or was of medium/low quality. Conclusion: Balint groups might help medical students to become more patient-centred, by increasing students’ empathic abilities and supporting their personal and professional growth. Groups are more subjectively effective when optional rather than compulsory. Discussion content is comparable to groups in continuing medical education.     

Perceptual grouping in visual word recognition

Four experiments are presented in which printed texts are read for their meaning. Some of the texts were mutilated by altering the size of selected letters. In Experiments 1, 2, and 3, the number of words mutilated per passage and the number of letters changed per word were both manipulated. In all three experiments, reading was slowed as a function of the number of words changed per passage, while the number of letters changed per word had a much smaller effect. The interaction between the number of words and number of letters changed was not significant in any of the experiments. It is difficult to explain these results merely in terms of changes in the discriminability of letters. In Experiment 2 all uppercase text was used, which argues against an explanation in terms of supraletter features such as word envelope. We propose an explanation in terms of visual attention and the perceptual grouping required prior to feature recognition. The last experiment supports this explanation through the counterintuitive finding that adding letters of intermediate size can improve legibility by allowing grouping processes to associate large and small letters as belonging to the same word object.
