Problems and solutions for a hybrid approach to grounding practical normativity

Source Hybridism about practical reasons is the position that facts that constitute reasons sometimes derive their normative force from external metaphysical grounds, and sometimes from internal. Although historically less popular than either Source Internalism or Source Externalism, hybridism has lately begun to garner more attention. Here, I further the hybridist's cause by defending Source Hybridism from three objections. I argue that we are not warranted in rejecting hybridism for any of the following reasons: that hybridists cannot provide an account of normative weight, that hybridists are committed to implausible results concerning practical deliberation, or that Source Hybridism is objectionably unparsimonious.     

False recognition of instruction-set lures

False remembering has been examined using a variety of procedures, including the Deese-Roediger-McDermott procedure, the false fame procedure and the two-list recognition procedure. We present six experiments in a different empirical framework examining false recognition of words included in the experimental instructions (instruction-set lures). The data show that participants' false alarm rate to instruction-set lures was twice their false alarm rate to standard lures. That result was statistically robust even when (1) the relative strength of targets to instruction-set lures was increased, (2) participants were warned about the instruction-set lures, (3) the instruction-set lures were camouflaged in the study instructions and (4) the instruction-set lures were presented verbally at study but visually at test. False recognition of instruction-set lures was only mitigated when participants were distracted between encountering the instruction-set lures and studying the training list. The results confirm the ease with which recognition succumbs to familiarity and demonstrate the robustness of false recognition.     

Effects of mode distinction,user visibility,and vehicle appearance on mode confusion when interacting with highly automated vehicles

Automated vehicles are expected to communicate with pedestrians at least during the introductory phase, for example, via LED strips, displays, or loudspeakers. While these are added to minimize confusion and increase trust, the human passenger within the vehicle could perform motions that a pedestrian could misinterpret as opposing the vehicle’s communication. To evaluate potential solutions to this problem, we conducted an online video-based within-subjects experiment (N = 59). The solutions under evaluation were mode distinction, vehicle appearance, and the visibility of the passenger via a tintable windshield. Our results show that especially the mode distinction and the conspicuous sensor attached to the automated vehicle showed positive effects. A tintable windshield, however, was negatively assessed. Thus, our work helps to design eHMI concepts to introduce automated vehicles safely by informing about feasible methods to avoid mode confusion.     

John Nash's Delusional Decade: A Case of Paranoid Schizophrenia

Continues the psychoanalytic study of mathematical genius John Nash in Capps (2003) by focusing on the decade, during his thirties, when he was most delusional. Explores the connections between the content of his delusions and his life history and immediate circumstances, with particular attention to the way in which his delusions reflected the bisexual confusion discussed in the previous essay. Uses Freud's analysis of the mechanism of paranoia in his Dr. Schreber study to account for the nature and progression of Nash's delusions.     

Source‐Goal Asymmetries in Motion Representation: Implications for Language Production and Comprehension

Recent research has demonstrated an asymmetry between the origins and endpoints of motion events, with preferential attention given to endpoints rather than beginnings of motion in both language and memory. Two experiments explore this asymmetry further and test its implications for language production and comprehension. Experiment 1 shows that both adults and 4‐year‐old children detect fewer within‐category changes in source than goal objects when tested for memory of motion events; furthermore, these groups produce fewer references to source than goal objects when describing the same motion events. Experiment 2 asks whether the specificity of encoding source/goal relations differs in both spatial memory and the comprehension of novel spatial vocabulary. Results show that endpoint configuration changes are detected more accurately than source configuration changes by both adults and young children. Furthermore, when interpreting novel motion verbs, both age groups expect more fine‐grained lexical distinctions in the domain of endpoint configurations compared to that of source configurations. These studies demonstrate that a cognitive‐attentional bias in spatial representation and memory affects both the detail of linguistic encoding during the use of spatial language and the specificity of hypotheses about spatial referents that learners build during the acquisition of the spatial lexicon.     

Mood, source characteristics, and message processing: A mood-congruent expectancies approach

Based on two lines of research, a model is proposed to explain when individuals in a positive mood as well as individuals in a negative mood invest more or less effort in message processing. First, research has shown that moods affect likelihood estimates. That is, positive (negative) mood leads to a mood-congruent increase regarding the occurrence of positively (negatively) valenced events. Second, research has shown that mood-unrelated expectancies affect message processing. Combining both lines of research, I argue that mood-congruent expectancies also affect message scrutiny, that is, more effortful processing given expectancy disconfirmation rather than expectancy confirmation. This prediction was tested in two experiments involving initial information regarding source honesty and likability, respectively. As predicted, individuals in both positive and negative moods evinced more effortful message processing when initial information disconfirmed rather than confirmed expectancies. Thus, these results are consistent with a quite flexible view of individuals in both positive and negative moods regarding the effort invested in information processing.     

Attack on the Self: Charismatic Leadership and Authoritarian Group Supervision

Charismatic group leadership carries the potential for indoctrination and abuse when countertransference issues remain unexamined. This paper is a personal account of participation by the author in an authoritarian and confrontational supervisory experience with self-serving charismatic leadership. Group casualties are portrayed and discussed. This report applies self-psychological principles to understand the powerful merger of the compliant self and idealized object. Further, the dynamics of group identification with the aggressor are described through the Ferenczian lens of confusion of tongues.     

Source monitoring in Alzheimer's Disease

Source monitoring is the process of making judgments about the origin of memories. There are three categories of source monitoring: reality monitoring (discrimination between self- versus other-generated sources), external monitoring (discrimination between several external sources), and internal monitoring (discrimination between two types of self-generated sources). We investigated whether Alzheimer's Disease (AD) patients, when compared with young and older adults, are impaired at the same level on the three source monitoring categories. We designed three tasks, one for each source monitoring category. In the first task, aimed at reality monitoring, participants had to remember whether objects were previously placed in a bag by themselves or by the experimenter. In the second task, assessing external monitoring, participants had to remember whether the experimenter had previously placed objects in the bag with a black or white gloved hand. In the third task, measuring internal monitoring, participants had to remember whether they had previously placed or imagined themselves placing objects in the bag. Participants showed worse performances in the external and internal monitoring tasks, when compared with reality monitoring. The external monitoring deficit was even more pronounced in AD patients. Regression analyses showed that variation in the external monitoring performances was reliably predicted by inhibition. Our results emphasize the role of inhibitory processes in AD patients' source monitoring decline. The close relation between source and inhibitory decline in AD is interpreted in terms of a common neural base for both concepts.
