People Wait Longer when the Alternative is Risky: The Relation Between Preferences in Risky and Inter‐temporal Choice

In two experiments, we demonstrate that despite indicating indifference when probed about risk or delay in isolation, when forced to explicitly trade‐off between the two, participants prefer delayed over risky rewards. This pattern of findings sets a boundary condition for any common utility‐based comparison process involving both risk and delay. Furthermore, this change from indifference‐in‐isolation to delay‐preference‐in‐a‐trade‐off strengthens as reward amount increases. Exploratory modeling results suggest that the shift in preference can be explained by allowing for different discount rates for delay‐only choices compared with when delay is in competition with risk. This explanation is better than one in which probability weighting is different between risk‐only choices and risks considered in the presence of a delay. Together, the empirical and modeling work lays a path for future investigations of why and when people's evaluation of the properties of risky and delayed choices vary as a function of the alternatives on offer.

Effects of absolute luminance and luminance contrast on visual discrimination in low mesopic environments

Recent research revealed considerable decline in visual perception under low luminance conditions. However, systematic studies on how visual performance is affected by absolute luminance and luminance contrast under low mesopic conditions (<0.5 cd/m²) is lacking. We examined performance in a simple visual discrimination task under low mesopic luminance conditions in three experiments in which we systematically varied base luminance and luminance contrast between stimulus and background. We further manipulated eccentricity of the stimuli because of known rods and cones gradients along the retina. We identified a “deficiency window” for performance as measured by d’ when luminance was < 0.06 cd/m² and luminance contrast as measured by the luminance ratio between stimulus and background was below < 1.7. We further calculated performance-based luminance as well as contrast efficiency functions for reaction times (RTs). These power functions demonstrate the contrast asymptote needed to decrease RTs and how such a decrease can be achieved given various combinations of absolute luminance and luminance contrast manipulations. Increased eccentricity resulted in slower RTs indicative of longer scan distances. Our data provide initial insights to performance-based efficiency functions in low mesopic environments that are currently lacking and to the physical mechanisms being utilized for visual perception in these extreme environments.     

A Defence of Weighted Lotteries in Life Saving Cases

The three most common responses to Taurek’s ‘numbers problem’ are saving the greater number, equal chance lotteries and weighted lotteries. Weighted lotteries have perhaps received the least support, having been criticized by Scanlon What We Owe to Each Other (1998) and Hirose ‘Fairness in Life and Death Cases’ (2007). This article considers these objections in turn, and argues that they do not succeed in refuting the fairness of a weighted lottery, which remains a potential solution to cases of conflict. Moreover, it shows how these responses actually lead to a new argument for weighted lotteries, appealing to fairness and Pareto-optimality.

Warnings given to observers can eliminate order effects

ObjectivesThe aim of the study was to examine the impact of warnings on order effects in attributions of ability.MethodQualified soccer coaches (N = 146) rated the ability of two soccer players (a control and target player) each shown, on video, performing a passing task eight times. For the control player, all participants saw the same footage in the same order. For the target player, participants viewed the same footage with half viewing a declining (successful to unsuccessful) performance pattern and half viewing an ascending pattern. Additionally, coaches either received no warning of the danger of order effects, a warning prior to viewing any footage, a warning prior to viewing the target player or a warning prior to rating the target player.ResultsResults indicated that primacy effects were observed in the no warning condition and the warning prior to rating the target. However, when warnings were given prior to observing the target player no order effects were observed.ConclusionThe results indicate that order effects can be eliminated by warning observers of the phenomenon.     

Affective atmospheres

In this paper I reflect on the concept of affective atmospheres in the context of the distinction between affect and emotion that has emerged in recent work on emotion, space and society. The concept of atmosphere is interesting because it holds a series of opposites -- presence and absence, materiality and ideality, definite and indefinite, singularity and generality -- in a relation of tension. To develop this account of atmosphere I juxtapose Marx's materialist imagination with a phenomenology attentive to singular affective qualities. By invoking a material imagination based on the movement and lightness of air, we learn from the former about the turbulence of atmospheres and their indeterminate quality. From the latter, we learn that atmospheres are singular affective qualities that emanate from but exceed the assembling of bodies. As such, to attend to affective atmospheres is to learn to be affected by the ambiguities of affect/emotion, by that which is determinate and indeterminate, present and absent, singular and vague.     

Framing and Editing Interpersonal Arguments

Since argument frames precede most other arguing processes, argument editing among them, one’s frames may well predict one’s preferred editorial standards. This experiment assesses people’s arguing frames, gives them arguments to edit, and tests whether the frames actually do predict editorial preferences. Modest relationships between argument frames and argument editing appear. Other connections among frames, editing, and additional individual differences variables are more substantial. Particularly notable are the informative influences of psychological reactance. A new theoretical contribution is offered, connecting argument frame research to Erving Goffman’s frame analysis.     

The Price of Pain and the Value of Suffering

ABSTRACT— Estimating the financial value of pain informs issues as diverse as the market price of analgesics, the cost-effectiveness of clinical treatments, compensation for injury, and the response to public hazards. Such valuations are assumed to reflect a stable trade-off between relief of discomfort and money. Here, using an auction-based health-market experiment, we show that the price people pay for relief of pain is strongly determined by the local context of the market, that is, by recent intensities of pain or immediately disposable income (but not overall wealth). The absence of a stable valuation metric suggests that the dynamic behavior of health markets is not predictable from the static behavior of individuals. We conclude that the results follow the dynamics of habit-formation models of economic theory, and thus, this study provides the first scientific basis for this type of preference modeling.     

Discerning the Relations Between Conversation and Cognition

Although hailing from cognate analytical schools, the contributors to Hedwig te Molder and Jonathan Potter’s edited volume Conversation and Cognition hold a remarkable diversity of views on the nature of “mental states” and their import for the purposes of analyzing naturally occurring interaction. I offer a critical analysis of some of the contributors’ discussions of cognition in social interaction in an effort to clarify some obstinate issues with respect to the meanings of words in our cognitive vocabulary (e.g. “thought” and “realization”) and their identification in analyses of conversation.     

Family interventions in psychosis: a scale to measure therapist adherence

The efficacy of family interventions in psychosis is well documented. UK and USA schizophrenia treatment guidelines advocate the practice of family interventions within routine clinical services. However, less attention has been paid to the study of treatment fidelity and the tools used in its assessment. This study reports the inter-rater reliability of a new scale: Family Intervention in Psychosis-Adherence Scale (FIPAS). This measure is designed to assess therapist adherence to the Kuipers et al . (2002) family intervention in psychosis treatment manual. Reliability ratings were based on a sample of thirteen audiotapes drawn from a randomized controlled trial of family intervention. The results indicated that the majority of items of the FIPAS had acceptable levels of inter-rater reliability. The findings are discussed in terms of their implications for the training and monitoring of the effectiveness of practitioners for family interventions in psychosis.
