“Metaphysische Ergebnisse”: Phenomenology and Metaphysics in Edmund Husserl’s <Emphasis Type="Italic">Cartesianische Meditationen</Emphasis> (§60). Attempt at Commentary

The main goal of the present paper is to offer a preliminary study of the relations between phenomenology and metaphysics in Husserl. After a brief presentation of what Husserl means by the term “metaphysics”, the rest of our research will consist of a detailed commentary on §60 of the Cartesian Meditations (Metaphysische Ergebnisse unserer Auslegung der Fremderfahrung). Our aim is to explain in what sense, according to Husserl, the “outcomes” of the phenomenological constitution of monadological intersubjectivity entail the solution to a traditional metaphysical problem, i.e., that of the existence of just one real world. The present investigation does not pretend to be more than an introduction. Besides shedding some light on a specific text, it will pave the way for a future inquiry into the relations between phenomenology and metaphysics in Husserl.     

Divided attention enhances the recognition of emotional stimuli: evidence from the attentional boost effect

The present study examined predictions of the early-phase-elevated-attention hypothesis of the attentional boost effect (ABE), which suggests that transient increases in attention at encoding, as instantiated in the ABE paradigm, should enhance the recognition of neutral and positive items (whose encoding is mostly based on controlled processes), while having small or null effects on the recognition of negative items (whose encoding is primarily based on automatic processes). Participants were presented a sequence of negative, neutral and positive stimuli (pictures in Experiment 1, words in Experiment 2) associated to target (red) squares, distractor (green) squares or no squares (baseline condition). They were told to attend to the pictures/words and simultaneously press the spacebar of the computer when a red square appeared. In a later recognition task, stimuli associated to target squares were recognised better than stimuli associated to distractor squares, replicating the standard ABE. More importantly, we also found that: (a) the memory enhancement following target detection occurred with all types of stimuli (neutral, negative and positive) and (b) the advantage of negative stimuli over neutral stimuli was intact in the DA condition. These findings suggest that the encoding of negative stimuli depends on both controlled (attention-dependent) and automatic (attention-independent) processes.     

Familicide: The killing of spouse and children

A familicide is a multiple-victim homicide incident in which the killer's spouse and one or more children are slain. National archives of Canadian and British homicides, containing 109 familicide incidents, permit some elucidation of the characteristic and epidemiology of this crime. Familicides were almost exclusively perpetrated by men, unlike other spouse-killings and other filicides. Half the familicidal men killed themselves as well, a much higher rate of suicide than among other uxoricidal or filicidal men. De facto unions were overrepresented, compared to their prevalence in the populations-at-large, but to a much lesser extent in familicides than in other uxoricides. Stepchildren were overrepresented as familicide victims, compared to their numbers in the populations-at-large, but to a much lesser extent than in other filicides; unlike killers of their genetic offspring, men who killed their stepchildren were rarely suicidal. An initial binary categorization of familicides as accusatory versus despondent is tentatively proposed. © 1995 Wiley-Liss, Inc.     

The attribute priming effect in patients with Alzheimer's disease

Experiments with semantic priming (SP) paradigms have documented early hypopriming in patients with AD when concepts are used as primes and attribute concept features as targets, suggesting that concept attributes are vulnerable to damage very early in the disease course. The aims of this study were to confirm early priming reduction in the attribute condition in patients with AD and to determine which of several semantic indexes (such as the level of distinctiveness, correlation or feature dominance of concept features) best predicts the priming effect size in AD. We administered an SP attribute condition paradigm to 20 mildly demented patients with AD and to 10 NCs. We used concept–attribute pairs for which normative data of semantic indexes relative to both concept primes (i.e., number, type, mean level of dominance, distinctiveness and correlation of features constituting the concepts) and target features (i.e., level of feature dominance, correlation and distinctiveness) were available. Results showed that compared to NCs, the AD group obtained very reduced priming facilitation. Furthermore, the item regression analyses showed that the priming decrement in the AD group was predicted by the feature dominance of the target in the related pairs; that is, the lower the target feature dominance, the lower the priming effect elicited. These results confirmed hypopriming in the attribute condition from the very early phase of AD and support the view that attributes which are more salient for the identification of a given concept are also those most resistant to semantic memory degradation in AD pathology.     

Trait gambling cognitions predict near-miss experiences and persistence in laboratory slot machine gambling

'Near-miss' outcomes (i.e., unsuccessful outcomes close to the jackpot) have been shown to promote gambling persistence. Although there have been recent advances in understanding the neurobiological responses to gambling near-misses, the psychological mechanisms involved in these events remain unclear. The goal of this study was to explore whether trait-related gambling cognitions (e.g., beliefs that certain skills or rituals may help to win in games of chance) influence behavioural and subjective responses during laboratory gambling. Eighty-four individuals, who gambled at least monthly, performed a simplified slot machine task that delivered win, near-miss, and full-miss outcomes across 30 mandatory trials followed by a persistence phase in extinction. Participants completed the Gambling-Related Cognitions Scale (GRCS; Raylu & Oei, 2004), as well as measures of disordered gambling (South Oaks Gambling Screen [SOGS]; Lesieur & Blume, 1987) and social desirability bias (DS-36; Tournois, Mesnil, & Kop, 2000). Skill-oriented gambling cognitions (illusion of control, fostered by internal factors such as reappraisal of losses, or perceived outcome sequences), but not ritual-oriented gambling cognitions (illusion of control fostered by external factors such as luck or superstitions), predicted higher subjective ratings of desire to play after near-miss outcomes. In contrast, perceived lack of self-control predicted persistence on the slot machine task. These data indicate that the motivational impact of near-miss outcomes is related to specific gambling cognitions pertaining to skill acquisition, supporting the idea that gambling near-misses foster the illusion of control.     

Doing the Right Thing: A Qualitative Investigation of Retractions Due to Unintentional Error

Retractions solicited by authors following the discovery of an unintentional error—what we henceforth call a “self-retraction”—are a new phenomenon of growing importance, about which very little is known. Here we present results of a small qualitative study aimed at gaining preliminary insights about circumstances, motivations and beliefs that accompanied the experience of a self-retraction. We identified retraction notes that unambiguously reported an honest error and that had been published between the years 2010 and 2015. We limited our sample to retractions with at least one co-author based in the Netherlands, Belgium, United Kingdom, Germany or a Scandinavian country, and we invited these authors to a semi-structured interview. Fourteen authors accepted our invitation. Contrary to our initial assumptions, most of our interviewees had not originally intended to retract their paper. They had contacted the journal to request a correction and the decision to retract had been made by journal editors. All interviewees reported that having to retract their own publication made them concerned for their scientific reputation and career, often causing considerable stress and anxiety. Interviewees also encountered difficulties in communicating with the journal and recalled other procedural issues that had unnecessarily slowed down the process of self-retraction. Intriguingly, however, all interviewees reported how, contrary to their own expectations, the self-retraction had brought no damage to their reputation and in some cases had actually improved it. We also examined the ethical motivations that interviewees ascribed, retrospectively, to their actions and found that such motivations included a combination of moral and prudential (i.e. pragmatic) considerations. These preliminary results suggest that scientists would welcome innovations to facilitate the process of self-retraction.
