Risk‐Taking Tendencies in Prisoners and Nonprisoners: Does Gender Matter?

Several investigations have found that prisoners are more likely than nonprisoners to engage in risky behavior, which may contribute to their propensity to commit criminal offenses. However, this research has been limited by an almost exclusive focus on male samples. Given the established link between risk taking and gender, it is thus unclear how findings on the risk‐taking propensities of prisoners also hold in women. The present study uses both a self‐report questionnaire (Domain‐Specific Risk Taking scale, DOSPERT) and a behavioral task (Balloon Analogue Risk Task, BART) to investigate risk‐taking tendencies in a Chinese prisoner group and a nonprisoner control group with balanced gender proportions. Across both genders, prisoners both indicated a higher risk‐taking tendency on the DOSPERT and showed more risk‐taking behavior on the BART than did nonprisoners. Importantly, the differences were considerably more pronounced in women than in men. Relative to nonprisoners, gender differences in risk taking were substantially smaller, or even reversed, in prisoners. Computational modeling of respondents' behavior in the BART revealed that the prisoners had higher reward sensitivity and lower response consistency than the nonprisoners; these differences were again more pronounced among women. Our results suggest that previous studies based primarily on male prisoners may have underestimated differences in risk taking between prisoners and nonprisoners, and that female prisoners may represent an even more extreme subpopulation than male prisoners.

Understanding Frege’s notion of presupposition

Why did Frege offer only proper names as examples of presupposition triggers? Some scholars claim that Frege simply did not care about the full range of presuppositional phenomena. This paper argues, in contrast, that he had good reasons for employing an extremely narrow notion of ‘Voraussetzung’. On Frege’s view, many devices that are now construed as presupposition triggers either express several thoughts at once or merely ‘illuminate’ a thought in a particular way. Fregean presuppositions, in contrast, are essentially tied to names.

     

How Affect Shapes Risky Choice: Distorted Probability Weighting Versus Probability Neglect

People's choices between prospects with relatively affect‐rich outcomes (e.g., medical side effects) can diverge markedly from their choices between prospects with relatively affect‐poor outcomes (e.g., monetary losses). We investigate the cognitive mechanisms underlying this “affect gap” in risky choice. One possibility is that affect‐rich prospects give rise to more distortion in probability weighting. Another is that they lead to the neglect of probabilities. To pit these two possibilities against each other, we fitted cumulative prospect theory (CPT) to the choices of individual participants, separately for choices between options with affect‐rich outcomes (adverse medical side effects) and options with affect‐poor outcomes (monetary losses); additionally, we tested a simple model of probability neglect, the minimax rule. The results indicated a qualitative difference in cognitive mechanisms between the affect‐rich and affect‐poor problems. Specifically, in affect‐poor problems, the large majority of participants were best described by CPT; in affect‐rich problems, the proportion of participants best described by the minimax rule was substantially higher. The affect gap persisted even when affect‐rich outcomes were supplemented by numerical information, thus providing no support for the thesis that choices in affect‐rich and affect‐poor problems diverge because the information provided in the former is nonnumerical. Our findings suggest that the traditional expectation‐based framework for modeling risky decision making may not readily generalize to affect‐rich choices.

Relations between 18-month-olds’ gaze pattern and target action performance: A deferred imitation study with eye tracking

Deferred imitation studies are used to assess infants’ declarative memory performance. These studies have found that deferred imitation performance improves with age, which is usually attributed to advancing memory capabilities. Imitation studies, however, are also used to assess infants’ action understanding. In this second research program it has been observed that infants around the age of one year imitate selectively, i.e., they imitate certain kinds of target actions and omit others. In contrast to this, two-year-olds usually imitate the model's exact actions. 18-month-olds imitate more exactly than one-year-olds, but more selectively than two-year-olds, a fact which makes this age group especially interesting, since the processes underlying selective vs. exact imitation are largely debated. The question, for example, if selective attention to certain kinds of target actions accounts for preferential imitation of these actions in young infants is still open. Additionally, relations between memory capabilities and selective imitation processes, as well as their role in shaping 18-month-olds’ neither completely selective, nor completely exact imitation have not been thoroughly investigated yet. The present study, therefore, assessed 18-month-olds’ gaze toward two types of actions (functional vs. arbitrary target actions) and the model's face during target action demonstration, as well as infants’ deferred imitation performance. Although infants’ fixation times to functional target actions were not longer than to arbitrary target actions, they imitated the functional target actions more frequently than the arbitrary ones. This suggests that selective imitation does not rely on selective gaze toward functional target actions during the demonstration phase. In addition, a post hoc analysis of interindividual differences suggested that infants’ attention to the model's social-communicative cues might play an important role in exact imitation, meaning the imitation of both functional and arbitrary target actions.     

The Seller's Sense: Buying–Selling Perspective Affects the Sensitivity to Expected Value Differences

Previous work comparing pricing decisions by buyers and sellers has primarily focused on the endowment effect, the phenomenon that selling prices exceed buying prices. Here, we examine whether pricing decisions by buyers and sellers also vary in sensitivity to differences between objects' expected values (EVs). Both a loss‐aversion account (which posits that losses are weighted more heavily than gains) and a loss‐attention account (which posits increased attention to a task when it involves possible losses) predict that pricing decisions by sellers should exhibit higher sensitivity. The latter, however, additionally predicts that this pattern should only emerge under certain conditions. In studies 1 and 2, we reanalyzed two published datasets in which participants priced monetary lotteries as sellers or buyers. It emerged that sellers showed greater EV sensitivity (defined as the rank correlation between the set price for each lottery and its EV) except in a condition with an extended deliberation time of 15 seconds. In study 3, the buyer–seller difference in EV sensitivity was replicated even when the pricing task was presented repeatedly, while in study 4, it was eliminated when buying and selling trials were randomly mixed. The reduction of the “seller's sense” in long deliberation and mixed trials settings supports an attentional resource‐based account of the differences between sellers and buyers in their EV sensitivity.

A Psycho-Educational Intervention for People with a Family History of Depression: Pilot Results

We developed and pilot-tested the first online psycho-educational intervention that specifically targets people with a family history of depression (‘LINKS’). LINKS provides genetic risk information and evidence-rated information on preventive strategies for depression and incorporates a risk assessment tool and several videos using professional actors. LINKS was pilot-tested in the general practitioner (GP) setting. The patient sample included people with a family history of at least one first-degree relative (FDR) with major depressive disorder (MDD) or bipolar disorder (BD). Patients attending participating GP practices were invited to enroll in the study by letter from their GP. Patients who self-identified as having at least one first-degree relative (FDR) with MDD or BD were eligible. Patients completed questionnaires, pre-post viewing LINKS, with measures assessing satisfaction, relevance, emotional impact and perceived improvement of understanding. Six GP practices participated, and 24 patients completed both questionnaires. Of these, all reported that they were satisfied or very satisfied with LINKS, and 74 % reported that LINKS met their expectations, and 21 % that it exceeded their expectations. LINKS was judged highly acceptable by this sample of GP attendees, and results indicate that an assessment of its effectiveness in a larger controlled trial is warranted.     

Aligning affordances of graphics with learning task requirements

Dynamic subject matter can be portrayed to learners in the form of either static or dynamic depictions. Two plausible bases for choosing a depiction format are alignment with the subject matter's dynamics, or the specific affordances a depiction provides for performing a particular learning output task. Experimental participants viewed an ordered set of eight images depicting key stages of a kangaroo hop presented in a dynamic, successive or simultaneous format. Control participants viewed no presentation. The output task required participants to rearrange a random sequence of the eight kangaroo images into the correct order of a kangaroo hop. Those who viewed the successive presentation were most successful in placing the images in their correct order while those in the dynamic condition were least successful. The results contradict the prevailing instructional design orthodoxy that the dynamic properties of a depiction should be aligned with the dynamic nature of the referent content.

Individual differences in metacontrast masking: A call for caution when interpreting group data

In this issue of Consciousness and Cognition, Bachmann (2010) comments on our study (Albrecht, Klapötke, & Mattler, 2010), which revealed two groups of observers with qualitative individual differences in metacontrast masking that are enhanced by perceptual learning. We are pleased that our study receives this attention and even more about Bachmann’s extremely positive comments. In this invited reply we argue that observers seem to be similar only at the beginning of the experiment but they have no choice as to which group to join. Findings strongly recommend to look at the data of individual subjects.     

Assessment of the Content and Process of Genetic Counseling: A Critical Review of Empirical Studies

This article reviews studies that assessed the process and content of genetic counseling communication. A systematic search of the literature was undertaken of studies that audio- or videotaped genetic counseling sessions conducted by genetics health care providers and subjected them to communication analyses. A total of 18 studies (published in 34 articles) were identified that met the eligibility criteria. Studies show that providers speak more than clients, that a large proportion of communication is biomedical rather than psychosocial and that the teaching model of genetic counseling is widely implemented. Higher levels of counselor facilitation of understanding and empathic responses, lower levels of verbal dominance (ratio of counselor to client talk) and the provision of a summary letter of the consultation are associated with more positive client outcomes. Findings from these studies should be used as an evidence base for teaching and continuing education of genetic counseling providers.
