Endogenous modulation of compatibility effects: an Investigation into the temporal dynamics

Compatibility effects (CEs) arise when multiple stimuli fall within the visual field, providing an indication of stimulus processing. Previous research demonstrated that exogenous factors (e.g., luminance) influence the magnitude of CEs and their time course. The current research investigated the influence of endogenous factors. We used a flanker paradigm with a variable temporal delay (SOA) between a flanker and a subsequent central stimulus appearing. To manipulate endogenous factors, we required responses to the flanker on either half or all of the trials. The results indicate that increasing the task relevance of the flanker strengthened the initial positive CE (measured at short SOAs), consistent with past findings related to exogenous factors. However, at longer SOAs, the CE did not reverse into a negative CE, which stands against findings related to exogenous factors. These results indicate that CEs are subject to endogenous modulation, but the temporal dynamics do not mimic exogenous modulation.     

The effects of health frame and target relevance in appearance social comparisons

Social comparison powerfully influences on appearance self‐evaluations, but previous research has not examined the combined impact of target frame and relevance on appearance comparison outcomes. The present study examined the effect of target relevance and health frame in body‐ideal images on self‐evaluations in a mixed‐gender university‐based sample from the United States (N = 176; 58% female). Participants were randomly assigned to one of four conditions in which they viewed a body‐ideal image of a same‐sex target that varied in target relevance (peer or model) and health frame (extreme behaviors described as being healthy or unhealthy). We did not find evidence that comparisons with models or peers are different in their effects. And, consistent with hypotheses, the health frame of a comparison target’s eating and exercise behaviors influenced how participants perceived themselves and their health. Participants were more likely to take health advice from the target described as healthy, and felt better about their own health when comparing to healthy targets. We also found gender differences such that men were more satisfied with their physical health but women were more satisfied with their appearance. Overall, this research supports the importance of addressing peer comparisons and health literacy in body image interventions, which has long‐term implications for the prevention of eating and exercise pathology.     

Probabilistic Cause and the Thirsty Traveler

In this paper I start by briefly presenting an analysis of token cause and of token causal relevance that I developed elsewhere, and then apply it to the famous thirsty traveler riddle. One general outcome of the analysis of causal relevance employed here is that in preemption cases (early or late) the preempted cause is not a cause since it is causally irrelevant to the effect. I consider several variations of the thirsty traveler riddle. In the first variation the first enemy emptied the canteen and the second enemy threw it away. On this variation, the act of neither enemy comes out, on the analysis employed here, as causally relevant to, and thus not as a cause of, the fact that the traveler died, but the conjunction of the two acts is a cause of it. This version is a case of mutual preemption. I argue that it has the same structure as the voting paradox, which thus has an analogous solution. In the standard version, in which the first enemy added poison to the water in the traveler's canteen, the act of the second enemy (who threw the canteen away) comes out, on the analysis used here, as causally relevant to and as a cause of the fact that the traveler died, but the act of the first enemy comes out as neither. I also make a comparison with Lewis' accounts, and discuss alternative treatments of the puzzle such as those of Hart and Honore and of Gavison, Margalit, and Ullmann-Margalit.     

Initial perceptions in negotiations: evaluation and response to ‘logrolling’ offers

In negotiations, where several issues are under consideration and parties have different priorities among these issues, integrative agreements can be reached through ‘logrolling’: concessions on low priority issues in exchange for gains on higher priority issues. The present research focuses on the potential role of initial offers in the development of integrative agreements. We show first, that in a simulated competitive market the specific composition of initial offers influences the final agreements, beyond the effect predicted by their overall value. In order to obtain some insight into the judgmental processes that might play a role, we explore the way in which inexperienced negotiators presented with a hypothetical negotiation context evaluate and respond to logrolling versus distributive initial offers. Three hypotheses were tested: logrolling offers convey an implicit message of cooperation, logrolling offers promote understanding of the mutual interest structure of the task, and, finally, logrolling offers establish within‐issue anchors. Results do not support the first two hypotheses: logrolling offers were not necessarily judged more attractive than distributive ones, and they did not seem to affect the deeply rooted fixed‐pie assumption. However, initial offers did establish within‐issue anchors: counter‐offers were affected by the specific composition of the initial offers beyond the effect of their overall value. This anchoring process resulted in logrolling offers yielding a higher profit for their initiator, as well as higher combined profits for both parties. Copyright © 2002 John Wiley & Sons, Ltd.     

Trustworthiness in explanation: The obligation to explain well

‘Scientific integrity’ certainly requires that data and references be beyond reproach. However, issues within the theory of scientific explanation suggest that there may be more to it than just this. While it is true that some contemporary, pragmatic analyses of explanation suffer from the ‘problem of relevance’ (an inability to ensure that explanations which are paradigmatic technically are relevant to the question being posed), it does not seem to be true that the addition of formal, metaphysical constraints is necessary to solve this problem. I argue that, when viewed as requests for help with an epistemic problem, explanation-seeking questions reveal the existence of a set of moral criteria centered in trust which, when satisfied, prevent trivial or irrelevant explanations from being offered, thereby broadening the concept of ‘scientific integrity’.     

Moral supervenience

Abstract

It is widely held, even among nonnaturalists, that the moral supervenes on the natural. This is to say that for any two metaphysically possible worlds w and w′, and for any entities x in w and y in w′, any isomorphism between x and y that preserves the natural properties preserves the moral properties. In this paper, I put forward a conceivability argument against moral supervenience, assuming non-naturalism. First, I argue that though utilitarianism may be true, and the trolley driver is permitted to kill the one to save the five, there is a conceivable scenario that is just like our world in all natural respects, yet at which deontology is true, and the trolly driver is not permitted to kill the one to save the five. I then argue that in the special case of morality, it is possible to infer from the conceivability of such a scenario to its possibility. It follows that supervenience is false.     

Multiple processes associated with self-esteem as a function of attribute types

Previous studies (e.g., [Pelham, B. W. (1995). Self-investment and self-esteem: evidence for a Jamesian model of self-worth. Journal of Personality and Social Psychology, 69, 1141–1150]) showed that self-esteem is positively associated with (1) perceived alignment of self-views with internal standards (Differential Importance: DI) and (2) perceived alignment of self-views with external-social standards (Normative Importance: NI). The present research shows that these processes of self-esteem differ as a function of the types of self-attributes that constitute self-esteem. Specifically, for attributes of high cultural relevance (i.e., indigenous attributes), self-esteem is positively related to DI but not NI; for attributes of lower cultural relevance, self-esteem is positively related to NI but not DI. Self-esteem is positively related to DI for both agentic and communal indigenous attributes, whereas it is also positively related to NI for communal indigenous attributes.     

社会信息加工中的相关性维度

在以往的社会信息加工研究中,多数情况只对刺激作积极、消极的效价区分,这往往导致实验结论中出现困惑和矛盾之处。Peeters提出了另一个区分刺激的维度:相关性(他相关、主相关)。Wentura等人把这一区分引入实验设计后,不但合理解释了以往研究中的问题和疑点,而且获得了新的发现。因此,相关性区分的引入对于此类研究有着重要意义,并对印象形成、刻板印象和群体等其他实验社会心理研究都有一定启发。
