Wittgenstein,Ethics and Basic Moral Certainty

Alice Crary claims that “the standard view of the bearing of Wittgenstein's philosophy on ethics” is dominated by “inviolability interpretations”, which often underlie conservative readings of Wittgenstein. Crary says that such interpretations are “especially marked in connection with On Certainty”, where Wittgenstein is represented as holding that “our linguistic practices are immune to rational criticism, or inviolable”. Crary's own conception of the bearing of Wittgenstein's philosophy on ethics, which I call the “intrinsically‐ethical reading”, derives from the influential New Wittgenstein school of exegesis, and is also espoused by James Edwards, Cora Diamond, and Stephen Mulhall. To my eyes, intrinsically‐ethical readings present a peculiar picture of ethics, which I endeavour to expose in Part I of the paper. In Part II I present a reading of On Certainty that Crary would call an “inviolability interpretation”, defend it against New Wittgensteinian critiques, and show that this kind of reading has nothing to do with ethical or political conservatism. I go on to show how Wittgenstein's observations on the manner in which we can neither question nor affirm certain states of affairs that are fundamental to our epistemic practices can be fruitfully extended to ethics. Doing so sheds light on the phenomenon that I call “basic moral certainty”, which constitutes the foundation of our ethical practices, and the scaffolding or framework of moral perception, inquiry, and judgement. The nature and significance of basic moral certainty will be illustrated through consideration of the strangeness of philosophers' attempts at explaining the wrongness of killing.     

Carry on winning: The gamblers’ fallacy creates hot hand effects in online gambling

People suffering from the hot-hand fallacy unreasonably expect winning streaks to continue whereas those suffering from the gamblers’ fallacy unreasonably expect losing streaks to reverse. We took 565,915 sports bets made by 776 online gamblers in 2010 and analyzed all winning and losing streaks up to a maximum length of six. People who won were more likely to win again (apparently because they chose safer odds than before) whereas those who lost were more likely to lose again (apparently because they chose riskier odds than before). However, selection of safer odds after winning and riskier ones after losing indicates that online sports gamblers expected their luck to reverse: they suffered from the gamblers’ fallacy. By believing in the gamblers’ fallacy, they created their own hot hands.     

Relationships between two dimensions of employee perfectionism,postwork cognitive processing,and work day functioning

This daily diary study examined relations between two distinct perfectionism dimensions and work-related cognitions experienced by employees during evening leisure time. Drawing from perseverative cognitive processing theory, we hypothesized that perfectionistic concerns would be related to work-related worry and rumination during post-work evenings. In contrast, we hypothesized that a theoretically more adaptive perfectionist dimension (perfectionistic strivings) would be associated with positively valenced self-reflections about work across consecutive evenings. A sample of 148 full-time workers completed an initial survey, which included a trait perfectionism measure, reported their work-related cognitions across four consecutive evenings of a working week, rated their sleep quality immediately upon awakening on each subsequent morning, and their daily levels of emotional exhaustion and work engagement at the end of each work day. Results showed that perfectionistic concerns were indirectly negatively associated with sleep quality and work day functioning via the tendency to worry and ruminate about work. In contrast, perfectionistic strivings were indirectly positively associated with work day engagement via the propensity to experience positive thoughts about work during evening leisure time. The theoretical and practical implications of these findings are discussed.     

Combining advice: the weight of a dissenting opinion in the consensus

We present two studies that evaluate how people combine advice and how they respond to outlying opinions. In a preliminary study, we found that individuals use discounting strategies when they encounter an extreme opinion in a small sample of opinions taken only once (a one‐shot advice‐taking situation). The main study examines the influence of outlying opinions (which may or may not be accurate) within a learning paradigm with feedback. This study shows that it is easy to reinforce a discounting strategy (with feedback) whereas it is more difficult to counteract this default strategy. In the discussion we consider cognitive, statistical, and strategic justifications for discounting opinions, from both theoretical and practical points of view.

Facilitating the emergence of convergent intraverbals in children with autism

Convergent intraverbals represent a specific type of intraverbal in which multiple components of one speaker's verbal behavior control a specific verbal response from another speaker (e.g., Speaker 1: What wooly, horned animal lives in the high country? Speaker 2: Bighorn sheep). To foster the development of advanced language, Sundberg and Sundberg (2011) proposed prerequisite skills that may engender the emergence of novel, convergent intraverbals. We used a multiple‐probe design with both nonconcurrent (across participants) and concurrent (across stimulus sets) components to evaluate the effects of training these prerequisite skills on the emergence of convergent intraverbals with four children with autism. Participants showed the emergence of convergent intraverbals at mastery levels after they displayed mastery performance on all of the prerequisite skills identified by Sundberg and Sundberg, lending support to their characterization as prerequisites. We discuss these findings in terms of operant mechanisms that may facilitate the development of generative language.     

Depictions of acne and psoriasis influence interpersonal aversion

The presence of a dermatological condition may deter contact with the affected person because it falsely signals the threat of infection. The current study investigated interpersonal aversion towards individuals with the appearance of acne and psoriasis. Participants (N = 196) either viewed a female face with the appearance of acne, psoriasis, or no visible dermatological condition. Participants rated the attractiveness of the person, and indicated their willingness for social and indirect contact with them. The person depicted with acne was rated significantly less attractive than the person with psoriasis or no dermatological condition. Participants reported significantly less willingness for indirect contact with the person depicted with acne or psoriasis compared to the person with no visible dermatological condition. In contrast, participants expressed more willingness for social contact with a person with acne than with the person with psoriasis or no dermatological condition. Group differences were significant when controlling for attractiveness ratings. Unwarranted fear of infection might underpin avoidance and discriminatory behaviour towards those with skin conditions. Further research is required to understand factors that influence avoidance of contact.     

Incomplete figure perception and invisible masking

The Gollin test (measuring recognition thresholds for fragmented line drawings of everyday objects and animals) has traditionally been regarded as a test of incomplete figure perception or 'closure', though there is a debate about how such closure is achieved. Here, figural incompleteness is considered to be the result of masking, such that absence of contour elements of a fragmented figure is the result of the influence of an 'invisible' mask. It is as though the figure is partly obscured by a mask having parameters identical to those of the background. This mask is 'invisible' only consciously, but for the early stages of visual processing it is real and has properties of multiplicative noise. Incomplete Gollin figures were modeled as the figure covered by the mask with randomly distributed transparent and opaque patches. We adjusted the statistical characteristics of the contour image and empty noise patches and processed those using spatial and spatial-frequency measures. Across 73 figures, despite inter-subject variability, mean recognition threshold was always approximately 15% of total contour in naive observers. Recognition worsened with increasing spectral similarity between the figure and the 'invisible' mask. Near threshold, the spectrum of the fragmented image was equally similar to that of the 'invisible' mask and complete image. The correlation between spectral parameters of figures at threshold and complete figures was greatest for figures that were most easily recognised. Across test sessions, thresholds reduced when either figure or mask parameters were familiar. We argue that recognition thresholds for Gollin stimuli in part reflect the extraction of signal from noise.     

‘When my mummy and daddy aren't looking at me when I do my maths she helps me’; Children can be taught to create imaginary companions: An exploratory study

Spontaneous imaginary companion (SIC) creation in childhood is a typical imaginative play behaviour associated with advanced sociocognitive skills; however, the direction of causality has not been established. To investigate this experimentally, researchers must determine whether children can create, on request, qualitatively equivalent imaginary companions (ICs) to those created spontaneously. We examined whether children could create ICs, and how these compared to SICs. Nine elementary school children were encouraged to create ICs in a 3-month intervention. Accounts of elicited ICs were compared with an age-matched sample of interviewees with SICs. Seven children maintained ICs for 6 months post intervention. Template analysis of IC interviews found four themes: Realistic Play, Multifaceted IC Mind, Utility of the IC, and Elicited IC Across Time. Analysis suggests elicited and SICs were similar in nature and utility, although intervention ICs tended to have animal rather than human appearances. Findings support the argument that children can be encouraged to create ICs similar to SICs.
