Ease of access to list items in short-term memory depends on the order of the recognition probes

We report data from 4 experiments using a recognition design with multiple probes to be matched to specific study positions. Items could be accessed rapidly, independent of set size, when the test order matched the study order (forward condition). When the order of testing was random, backward, or in a prelearned irregular sequence (reordered conditions), the classic Sternberg result was obtained: Response times were slow and increased linearly with set size. A number of explanations for forward-condition facilitation were ruled out, such as the predictability of the study order (Experiment 2), the predictability of the probe order (Experiment 1), the covariation of study and test orders (Experiments 1, 2, and 4), processes of probe encoding and perception that did not rely on STM access (Experiments 1, 2, and 4), specific support of the forward condition by articulatory processes (Experiment 3), or condition-dependent strategic differences (Experiment 4). More detailed analyses demonstrated that fast forward responses could not be accounted for by the effects of input position and output position that modulated random responses, effects that did account for the slower responses of the reordered conditions (Experiments 1, 3, and 4). A final analysis of probe-to-probe transitions as a function of encoding distance revealed a sizeable single-step benefit in the random condition. We concluded that STM representations were serial rather than spatial and that forward probes benefited from their serial adjacency.     

Blushing-Fearful Individuals’ Judgmental Biases and Conditional Cognitions: An Internet Inquiry

The present study examines two mechanisms that might explain why blushing-fearful individuals fear blushing: Judgmental biases for blushing in ordinary social situations that usually do not elicit a blush, and negative conditional cognitions about blushing irrespective of situation. A web-based self-report measure, linked to a German internet forum for people with fear of blushing, was completed by a group of high blushing-fearful participants (n = 155) and a low fear group (n = 61). Supporting the idea that cognitive biases are involved in fear of blushing, blushing-fearful participants showed inflated estimates of both the probability and the costs of blushing in these situations. In addition, blushing-fearful individuals were characterized by relatively negative conditional cognitions about blushing.     

Lipopolysaccharide-induced experimental immune activation does not impair memory functions in humans

Reconsolidation studies have led to the hypothesis that memory, when labile, would be modified in order to incorporate new information. This view has reinstated original propositions suggesting that short-term memory provides the organism with an opportunity to evaluate and rearrange information before storing it, since it is concurrent with the labile state of consolidation. The Chasmagnathus associative memory model is used here to test whether during consolidation it is possible to change some attribute of recently acquired memories. In addition, it is tested whether these changes in behavioral memory features can be explained as modifications on the consolidating memory trace or as a consequence of a new memory trace. We show that short-term memory is, unlike long-term memory, not context specific. During this short period after learning, behavioral memory can be updated in order to incorporate new contextual information. We found that, during this period, the cycloheximide retrograde amnesic effect can be reverted by a single trial in a new context. Finally, by means of memory sensitivity to cycloheximide during consolidation and reconsolidation, we show that the learning of a new context (CS) during this short-term memory period builds up a new memory trace that sustains the behavioral memory update.     

Von den Schwierigkeiten, Analytiker zu werden

The results of a study concerning the social situation of students in psychoanalytic training in DPG institutes are presented. The study based on a questionnaire worked out at the meetings of the spokesmen of DPG candidates as a reaction to the changing external conditions. The Psychotherapist Act, the introduction of a new medical specialization and the planning of demand have put a considerable strain on the training conditions and have led to reduced numbers of applicants also because more and more competing, low cost training courses for psychotherapy have come onto the market. Data are presented concerning age, gender, marital status of students, beginning and termination of training, original profession of students, means of funding, frequency and costs of training analysis and supervision, as well as monthly income and expenses. The findings show for example that students nowadays are considerably older than they used to be (see Pohl 1974 and Pollmann 1985), the number of men in training decreased as well as the number of physicians while the number of women and psychologists increased. The frequency and the expenses for training analysis strongly increased while the income decreased. Many students therefore can no longer fund their training by their current income. In addition the assumption is confirmed that psychoanalytic training takes considerably longer than required by the law. As a consequence it seems necessary to reduce costs and duration of training in order to keep psychoanalytic training competitive and practicable for applicants. Therefore it is proposed by the authors to give credit for theory acquired elsewhere, to start treating patients at earlier stages of training, to allow group supervision on a larger scale and to bring the costs for training analysis and supervision in line with the rates paid by the health insurance companies in order to keep costs manageable. Other means of support, such as scholarships or reasonable loans are discussed. It is proposed to promote and further use the innovative and creative potential of candidates at an early stage to prompt research and development of psychoanalysis. It is imperative to promote psychoanalysis in the public so that it can defend its place in society and make its contribution to public health.     

Forgetting unwanted memories: directed forgetting and thought suppression methods

Experimental psychopathologists have tested hypotheses regarding mechanisms that ought to be operative if victims possess skills for forgetting material related to trauma. In this article, we review research on directed forgetting and thought suppression paradigms, concentrating on laboratory studies involving attempts by individuals reporting trauma histories to forget emotionally negative material. Most studies have shown that trauma survivors, especially those with post-traumatic stress disorder, are characterized by a breakdown in the ability to forget disturbing material. Studies on individuals reporting repressed or recovered memories of trauma have not confirmed predictions regarding heightened forgetting skills for trauma-related words. However, recent research on suppressing disturbing autobiographical memories suggests that people who report spontaneously recalling childhood abuse outside of psychotherapy may, indeed, possess skills for not thinking about disturbing material.     

When,why, and how do People Deviate from Physical Distancing Measures During the COVID-19 Pandemic: A Mixed-Methods Study

Introduction:To limit the spread of COVID-19, many countries, including Belgium, have installed physical distancing measures. Yet, adherence to these newly installed behavioral measures has been described as challenging and effortful. Based on the Health Action Process Approach (HAPA) model, this study performed an in-depth evaluation of when, why, and how people deviated from the physical distancing measures.Methods:An online mixed-method study was conducted among Belgian adults (N = 2055) in the beginning of May 2020. Participants were recruited via an open call through email and social media platforms, using snowball sampling. Conditions wherein people deviated from the physical distancing measures were assessed by means of an open-ended question. HAPA determinants were assessed in a quantitative way.Results:Half of the sample reported to deviate from the measures. Further, deviation from the measures was associated with each determinant outlined by the HAPA. Findings highlight that many people deviated from the measures because of their need for social contact. The majority of the people who deviated from the measures stated that they carefully weighed the risks of their behavior.Conclusions:Need for social contact pushed people to deviate from physical distancing measures in a deliberate manner. Potential areas for future interventions aimed at promoting adherence to physical distancing measures and enhancing psychosocial well-being are discussed.     

Cognitive Mechanisms Underlying Recovered-Memory Experiences of Childhood Sexual Abuse

ABSTRACT— People sometimes report recovering long-forgotten memories of childhood sexual abuse. The memory mechanisms that lead to such reports are not well understood, and the authenticity of recovered memories has often been challenged. We identified two subgroups of people reporting recovered memories of childhood sexual abuse. These subgroups differed dramatically in their cognitive profiles: People who recovered memories of abuse through suggestive therapy exhibited a heightened susceptibility to the construction of false memories, but showed no tendency to underestimate their prior remembering. Conversely, people who recovered memories of abuse spontaneously showed a heightened proneness to forget prior incidences of remembering, but exhibited no increased susceptibility to false memories. This double dissociation points to mechanisms that underlie recovered-memory experiences and indicates that recovered memories may at times be fictitious and may at other times be authentic.     

Prototypical Behaviour Patterns of Social Intelligence: An Intercultural Comparison between Chinese and German Subjects

By using the Act Frequency Approach (Buss & Craik, 1980), Chinese subjects (N = 31) generated a list of acts (specific behaviours) considered to represent social intelligence. These acts were rated by Chinese subjects (N = 39) and German subjects (N = 29) for prototypicality. A comparison of results showed that the construct of social intelligence is culture dependent. For the Chinese, social intelligent behaviours seem to reflect the classical traditions and ideals of Confucianism. Acts that received the highest scores were those that described conforming to and fulfilling expected roles, and acts in which the wellbeing of the entire society was described as being more important that the desires of an individual. This was especially true for older subjects and for women. Items controlling for socially desirable behaviour and social engagement showed clear differences between the two cultures; as expected, the German subjects rated these items lower, whereas the Chinese subjects found both items to be high prototypical of social intelligence.
