The being a patient effect: negative expectations based on group labeling and corresponding treatment affect patient performance

Patient studies provide insights into mechanisms underlying diseases and thus represent a cornerstone of clinical research. In this study, we report evidence that differences between patients and controls might partly be based on expectations generated by the patients’ knowledge of being invited and treated as a patient: the Being a Patient effect (BP effect). This finding extends previous neuropsychological reports on diagnosis threat. Participants with mild allergies were addressed either as patients or control subjects in a clinical study. We measured the impact of this group labeling and corresponding instructions on pain perception and cognitive performance. Our results provide evidence that the BP effect can indeed affect physiological and cognitive measures in clinical settings. Importantly, these effects can lead to systematic overestimation of genuine disease effects and should be taken into account when disease effects are investigated. Finally, we propose strategies to avoid or minimize this critical confound.     

Psychotherapeuten und Internet

Background

Communication is part and parcel of every interaction. This raises the question of the role of modern media in mental health care. The aim of this explorative study was to investigate the use of modern media in the clinical practice.

Material and methodology

In an Internet survey 234 psychotherapists from Nordrhein-Westfalen (NRW) were surveyed about the extent to which they integrate new media in the practice and their opinion about this integration. For this purpose a questionnaire was developed based on the questionnaire of Wangberg et al. (2007).

Results

Most of the psychotherapists already use e-mails as well as mobile communication to contact their patients. The main reason for choosing this modern way of communication is the possibility to simplify the management of formal issues. Psychotherapists were indifferent about the idea of web-based counseling.

Conclusion

Forms of digital media are used as an addition to conventional ways of therapeutic communication but face-to-face interaction cannot be replaced completely which is also indicated by the fact that professionals still highly value personal contact.     

How Inspecting a Picture Affects Processing of Text in Multimedia Learning

We investigated how a picture fosters learning from text, both with self‐paced presentation and with short presentation before text. In an experiment, participants (N = 114) learned about the structure and functioning of a pulley system in one of six conditions: text only, picture presentation for 150 milliseconds, 600 milliseconds, or 2 seconds, or self‐paced before text, or self‐paced concurrent presentation of text and picture. Presenting the picture for self‐paced study time, both before and concurrently with text, fostered recall and comprehension and sped up text processing compared with presenting text only. Moreover, even inspecting the picture for only 600 milliseconds or 2 seconds improved comprehension and yielded faster reading of subsequent text about the spatial structure of the system compared with text only. These findings suggest that pictures, even if attended for a short time only, may yield a spatial mental scaffold that allows for the integration with verbal information, thereby fostering comprehension.

Assessing implicit motives with an online version of the picture story exercise

An online version of a Picture Story Exercise (PSE) was administered to 180 participants to assess implicit motives for achievement, affiliation, and power. First, data were analyzed with respect to different aspects of participant behavior (dropout, writing time, story length, setting). Second, online data were compared with data collected in the laboratory (n = 93). Results regarding motive density, internal consistency, picture profiles, and position effects were comparable among samples and consistent with previous research (Pang and Schultheiss in J Person Assess 85:280–294, 2005; Schultheiss and Brunstein in J Person Assess 77: 71–86, 2001). In addition, online participants completed self-report measures assessing explicit motives and the Big Five personality factors. Explicit motives showed no substantial overlap with PSE motive scores, replicating previous research. Personality factors revealed gender differences in correlates: men with a high implicit power motive reported less agreeableness and conscientiousness. Results suggest that administering the PSE online yields reliable and valid data.     

The psychometrics of photographic cropping: the influence of colour, meaning, and expertise

Cropping is the central act of photography, the viewfinder of a camera being used to crop a portion of the visual world which is then surrounded with a frame. Six studies are described which show that the act of cropping is carried out reliably and confidently by both expert and non-expert participants. Two studies confirm that some croppers are better croppers than others, their cropped images being preferred aesthetically over the croppings of less-good croppers. Colour had little impact on cropping decisions, whereas thresholded monochrome images ('Mooney images') dramatically altered crop positions. That suggests that cropping can be driven top-down, by the meaning of objects in photographs, but the fact that the Mooneyised images are still cropped consistently, suggests that image structure, perhaps in the form of low-level image properties, may still be important. Experts crop pictures differently from non-experts, and they take longer, viewing a wider range of possible crops, pausing longer to assess crops, and using more formal terminology when reflecting on their cropping decisions. Experts' crops are not, however, preferred more, either by non-expert viewers or by expert viewers. Cropping, it is suggested, is an ideal paradigm for experimental aesthetics, allowing precise experimental control with Fechner's Method of Production, a technique which normally is not easy to use.

Distributing mathematical practice of third and seventh graders: Applicability of the spacing effect in the classroom

We examined the effect of distributed practice on the mathematical performance of third and seventh graders (N = 213) in school. Students first received an introduction to a mathematical topic, derived from their curriculum. Thereafter, they practiced in one of two conditions. In the massed condition, they worked on three practice sets in 1 day. In the distributed condition, they worked on one practice set per day for 3 consecutive days. Bayesian analyses of the performance in two follow‐up tests 1 and 6 weeks after the last practice set revealed a positive effect of distributed practice as compared with massed practice in Grade 7. In Grade 3, a positive effect of distributed practice was supported by the data only in the test 1 week after the last practice set. The results suggest that distributed practice is a powerful learning tool for both elementary and secondary school students in the classroom.     

Emotional deficiency and psychopathy

Aside from an antisocial life-style, the concept of psychopathy is based on character features which can be described in terms of specific patterns of interpersonal, behavioral, and, in particular, affective characteristics. Concluding from studies which have dealt with the affective domain in psychopaths, emotional deficiency may predispose to violence in several ways. (1) Poor conditioning implicates a failure to review the harmful consequences of one's actions leading to a deficit of avoidance behavior. (2) Emotional detachment prevents experiencing feelings, which naturally inhibit the acting out of violent impulses. (3) Emotional deficiency is closely associated with a general underarousal, leading to sensation seeking. Current data suggest that there may be a close association between difficulties in emotional processing and poor prefrontal functioning. From a psychosocial perspective, psychopaths were shown to have been exposed to severe familial and societal difficulties. Whether biological or environmental factors dominate in the etiology of this personality disorder, psychopathy does not per se justify the assumption of decreased legal responsibility.
