From recognition to decisions: Extending and testing recognition-based models for multialternative inference

The recognition heuristic is a noncompensatory strategy for inferring which of two alternatives, one recognized and the other not, scores higher on a criterion. According to it, such inferences are based solely on recognition. We generalize this heuristic to tasks with multiple alternatives, proposing a model of how people identify the consideration sets from which they make their final decisions. In doing so, we address concerns about the heuristic’s adequacy as a model of behavior: Past experiments have led several authors to conclude that there is no evidence for a noncompensatory use of recognition but clear evidence that recognition is integrated with other information. Surprisingly, however, in no study was this competing hypothesis—the compensatory integration of recognition—formally specified as a computational model. In four studies, we specify five competing models, conducting eight model comparisons. In these model comparisons, the recognition heuristic emerges as the best predictor of people’s inferences.     

A signal-detection analysis of fast-and-frugal trees

Models of decision making are distinguished by those that aim for an optimal solution in a world that is precisely specified by a set of assumptions (a so-called "small world") and those that aim for a simple but satisfactory solution in an uncertain world where the assumptions of optimization models may not be met (a so-called "large world"). Few connections have been drawn between these 2 families of models. In this study, the authors show how psychological concepts originating in the classic signal-detection theory (SDT), a small-world approach to decision making, can be used to understand the workings of a class of simple models known as fast-and-frugal trees (FFTs). Results indicate that (a) the setting of the subjective decision criterion in SDT corresponds directly to the choice of exit structure in an FFT; (b) the sensitivity of an FFT (measured in d') is reflected by the order of cues searched and the properties of cues in an FFT, including the mean and variance of cues' individual d's, the intercue correlation, and the number of cues; and (c) compared with the ideal and the optimal sequential sampling models in SDT and a majority model with an information search component, FFTs are extremely frugal (i.e., do not search for much cue information), highly robust, and well adapted to the payoff structure of a task. These findings demonstrate the potential of theory integration in understanding the common underlying psychological structures of apparently disparate theories of cognition.     

Intuitive and deliberate judgments are based on common principles

A popular distinction in cognitive and social psychology has been between intuitive and deliberate judgments. This juxtaposition has aligned in dual-process theories of reasoning associative, unconscious, effortless, heuristic, and suboptimal processes (assumed to foster intuitive judgments) versus rule-based, conscious, effortful, analytic, and rational processes (assumed to characterize deliberate judgments). In contrast, we provide convergent arguments and evidence for a unified theoretical approach to both intuitive and deliberative judgments. Both are rule-based, and in fact, the very same rules can underlie both intuitive and deliberate judgments. The important open question is that of rule selection, and we propose a 2-step process in which the task itself and the individual's memory constrain the set of applicable rules, whereas the individual's processing potential and the (perceived) ecological rationality of the rule for the task guide the final selection from that set. Deliberate judgments are not generally more accurate than intuitive judgments; in both cases, accuracy depends on the match between rule and environment: the rules' ecological rationality. Heuristics that are less effortful and in which parts of the information are ignored can be more accurate than cognitive strategies that have more information and computation. The proposed framework adumbrates a unified approach that specifies the critical dimensions on which judgmental situations may vary and the environmental conditions under which rules can be expected to be successful.     

Ambulante Psychotherapie in Deutschland aus Sicht der Patienten

This study analyzed the provision of outpatient psychotherapy services in Germany in standard practice settings. A total of 1,212 subjects who received or were still receiving outpatient psychotherapy during the past 6 years provided information about their experiences via a telephone survey. Outpatient psychotherapy was sought for many different conditions and was rated as highly effective. The improvement rates for all complaints were higher than 50%, except for obesity (37%) and sexual dysfunctions (44%). Patient ratings of worsening were less than 8% throughout. Treatment had very positive results not only for target symptoms but also for other aspects of patients?? lives. Almost 90% of those questioned stated that they were satisfied with their therapist. High agreement ratings were reported specifically with respect to positive therapeutic relationship, stable working alliance, experience of autonomy during therapy and therapists?? competency and ethical conduct. Patients gave their psychotherapists excellent evaluations and were highly satisfied with the changes achieved through treatment.     

Placebo-mediated, Naloxone-sensitive suggestibility of short-term memory performance

Physiological studies of placebo-mediated suggestion have been recently performed beyond their traditional clinical context of pain and analgesia. Various neurotransmitter systems and immunological modulators have been used in successful placebo suggestions, including Dopamine, Cholecystokinin and, most extensively, opioids. We adhered to an established conceptual framework of placebo research and used the μ-opioid-antagonist Naloxone to test the applicability of this framework within a cognitive domain (e.g. memory) in healthy volunteers. Healthy men (n=62, age 29, SD=9) were required to perform a task-battery, including standardized and custom-designed memory tasks, to test short-term recall and delayed recognition. Tasks were performed twice, before and after intravenous injection of either NaCl (0.9%) or Naloxone (both 0.15 mg/kg), in a double-blind setting. While one group was given neutral information (S-), the other was told that it might receive a drug with suspected memory-boosting properties (S+). Objective and subjective indexes of memory performance and salivary cortisol (as a stress marker) were recorded during both runs and differences between groups were assessed. Short-term memory recall, but not delayed recognition, was objectively increased after placebo-mediated suggestion in the NaCl-group. Naloxone specifically blocked the suggestion effect without interfering with memory performance. These results were not affected when changes in salivary cortisol levels were considered. No reaction time changes, recorded to uncover unspecific attentional impairment, were seen. Placebo-mediated suggestion produced a training-independent, objective and Naloxone-sensitive increase in memory performance. These results indicate an opioid-mediated placebo effect within a circumscribed cognitive domain in healthy volunteers.     

Autismus oder „Psychopathy“?

According to the concept of Hare autism spectrum disorders and psychopathy are associated with a strong deficit in empathy. However, empathy deficits in patients suffering from autism spectrum disorders and empathy deficits in individuals with psychopathic personality traits appear to be different. Some authors described the comorbid occurrence of psychopathic personality traits/psychopathy in individuals with autism spectrum disorders. The following article aims to approach this differential diagnostic problem by a brief review of the literature on a casuistic basis. This article reports the case of a highly remarkable 17-year-old adolescent. The case will be discussed according to the construct of psychopathy with reference to the concept of Hare.     

Einstellungen zu Psychotherapie

In a representative survey 2,129 subjects were questioned about their attitudes towards outpatient psychotherapy. This study was carried out on behalf of the Apotheken Umschau (Pharmacy Review) by the “GfK Nürnberg” (Society for Consumer Research Nuremberg) from January 2012 to February 2012. In the survey also people who had once received or were currently undergoing outpatient psychotherapy took part and these respondents were surveyed about their reasons for seeking treatment and their experiences with outpatient psychotherapy. When available results were compared with the findings from a survey carried out in 2003. The majority of respondents appraised psychotherapy as being essential and helpful in treating mental disorders and as being useful in personal crises. Women were more open-minded about psychotherapy than men; nevertheless 34 % considered that it would be embarrassing if neighbours or friends were aware that they were undergoing psychotherapy. Of the respondents 28 % categorically excluded psychotherapy for themselves, 216 declared that they had undergone psychotherapy and of the latter 83 % judged the psychotherapy to be successful.     

Social norms and the likelihood of raping: Perceived rape myth acceptance of others affects men's rape proclivity

Research showing that rape myth acceptance (RMA) causally affects rape proclivity (RP) was extended by examining the impact of RMA-related norms on RP. Male students (total N = 264) received feedback about the alleged responses of other students to RMA items either before (Experiment 1) or after (Experiment 2) they reported their own RMA, and then their RP was assessed using acquaintance-rape scenarios. The level of RMA feedback was varied. Results showed that higher norms led to higher RP. In Experiment 1, this effect was mediated via self-reported RMA. Experiment 2 yielded main effects of both RMA feedback and self-reported RMA and an interaction effect showing that RMA feedback was particularly influential at higher levels of own RMA. Theoretical and practical implications of these findings are discussed.
