Moral objectivism across the lifespan

We report the results of two studies that examine folk metaethical judgments about the objectivity of morality. We found that participants attributed almost as much objectivity to ethical statements as they did to statements of physical fact and significantly more objectivity to ethical statements than to statements about preferences or tastes. In both studies, younger participants attributed less objectivity to ethical statements than older participants. Females were observed to attribute slightly less objectivity to ethical statements than males, and we found important interactions between attributions of objectivity and other factors, such as how strong participants’ moral opinions were and how much disagreement about the issue they perceived to exist within society. We believe our results have significant implications for debates about the nature of folk morality and about the nature of morality in general.     

Objective Explanations of Individual Well-being

Empirical research on questions pertaining to individual well-being is informed by the researchers' philosophical conception of the nature of well-being and, consequently, the adequacy of such research is partly determined by the plausibility of this conception. Philosophical theories of human well-being divide into subjective and objective. Subjective theories make our well-being dependent on our attitudes of favour and disfavour. Objective theories deny this dependency. This article discusses objective theories of individual well-being from the point of view of their explanatory power and argues that these theories are unable to provide an acceptable account of the prudential goodness of what they consider to be good for human beings. The article concludes by discussing some implications of its main argument to empirical research on questions pertaining to individual well-being.

幽默平面广告的适用性研究

为了探讨哪一类别商品的平面广告更适合于采用幽默的诉求方式,研究随机选取160大学生为被试,以16则改编平面广告为实验材料,以广告类型（幽默,非幽默）、商品类别为自变量,以广告评价、广告顺序为协变量,以商品的印象程度、喜爱程度、购买意向为因变量,进行平衡设计实验。结果表明,幽默广告具有较好广告效果,可以提高受众对大宗工具、小奖赏和小工具型商品的记忆;幽默平面广告更适用于低风险、功能性商品,不适用于高风险、享乐性商品。     

Representationalism and the conceivability of inverted spectra

Most philosophers who have endorsed the idea that there is such a thing as phenomenal content—content that supervenes on phenomenal character—have also endorsed what I call Standard Russellianism. According to Standard Russellianism, phenomenal content is Russellian in nature, and the properties represented by perceptual experiences are mind-independent physical properties. In agreement with Sydney Shoemaker [Shoemaker, S. (1994). Philosophy and Phenomenological Research, 54 249–314], I argue that Standard Russellianism is incompatible with the possibility of spectrum inversion without illusion. One defense of Standard Russellianism is to hold that spectrum inversion without illusion is conceivable but not in fact possible. I argue that this response fails. As a consequence, either phenomenal content is not Russellian, or experiences do not represent mind-independent physical properties.     

The psychology of meta-ethics: exploring objectivism

How do lay individuals think about the objectivity of their ethical beliefs? Do they regard them as factual and objective, or as more subjective and opinion-based, and what might predict such differences? In three experiments, we set out a methodology for assessing the perceived objectivity of ethical beliefs, and use it to document several novel findings. Experiment 1 showed that individuals tend to regard ethical statements as clearly more objective than social conventions and tastes, and almost as objective as scientific facts. Yet, there was considerable variation in objectivism, both across different ethical statements, and across individuals. The extent to which individuals treat ethical beliefs as objective was predicted by the way they grounded their ethical systems. Groundings which emphasize the religious, pragmatic, and self-identity underpinnings of ethical belief each independently predicted greater ethical objectivity. Experiment 2 replicated and extended these findings with a refined measure of ethical objectivism. Experiment 3 demonstrated the robustness of the religious grounding of ethics, and differentiates it from mere religious belief and from political orientation. The results shed light on the nature of ethical belief, and have implications for the resolution of ethical disputes.     

Right hemisphere specialization for color detection

Three experiments were carried out to investigate hemispheric asymmetry in color processing among normal participants. In Experiment 1, it was shown that the reaction times (RTs) of the dominant and non-dominant hands assessed using a visual target presented at the central visual field, were not significantly different. In Experiment 2, RTs of ipsilateral hands to lateralized chromatic stimuli revealed that the processing time was 17 ms shorter in the right hemisphere (RH) than that in the left hemisphere among the right-handed participants, whereas no significant difference was found among the left-handed participants. On the other hand, RTs to lateralized achromatic stimuli showed no such asymmetry among both the right- and left-handed participants (Experiment 3). These findings strongly suggest RH superiority for detection of color among right-handed individuals.     

The role of a mentoring group for family therapy trainees and therapists of color

This article discusses the development, process, and impact of a mentoring group for family therapists of color. A within-group process for trainees of color in a predominantly White institution can provide a valuable resource for support, validation, empowerment, and collective action. The article examines how such mentoring promotes the effectiveness of therapists of color, as well as the practices and goals of social justice and diversity within training institutions and the field in general. Reflections and recommendations for implementing such a group are offered, as well as a personal narrative of a group member's experience of finding her voice in the group.     

Thresholds for color discrimination in English and Korean speakers

Categorical perception (CP) is said to occur when a continuum of equally spaced physical changes is perceived as unequally spaced as a function of category membership (Harnad, S. (Ed.) (1987). Psychophysical and cognitive aspects of categorical perception: A critical overview. Cambridge: Cambridge University Press). A common suggestion is that CP for color arises because perception is qualitatively distorted when we learn to categorize a dimension. Contrary to this view, we here report that English speakers show no evidence of lowered discrimination thresholds at the boundaries between blue and green categories even though CP is found at these boundaries in a supra-threshold task. Furthermore, there is no evidence of different discrimination thresholds between individuals from two language groups (English and Korean) who use different color terminology in the blue-green region and have different supra-threshold boundaries. Our participants’ just noticeable difference (JND) thresholds suggest that they retain a smooth continuum of perceptual space that is not warped by stretching at category boundaries or by within-category compression. At least for the domain of color, categorical perception appears to be a categorical, but not a perceptual phenomenon.     

More is more: The relationship between vocabulary size and word extension

This study experimentally tested the relationship between children’s lexicon size and their ability to learn new words within the domain of color. We manipulated the size of 25 20-month-olds’ color lexicons by training them with two, four, or six different color words over the course of eight training sessions. We subsequently tested children’s ability to extend new color words to new instances. We found that training with a broader number of color words led to increased extension of new words. The results suggest that children’s learning history predicts their ability to learn new words within domains.     

Neurophysiological evidence for categorical perception of color

The aim of this investigation was to examine the time course and the relative contributions of perceptual and post-perceptual processes to categorical perception (CP) of color. A visual oddball task was used with standard and deviant stimuli from same (within-category) or different (between-category) categories, with chromatic separations for within- and between-category stimuli equated in Munsell Hue. CP was found on a behavioral version of the task, with faster RTs and greater accuracy for between- compared to within-category stimuli. On a neurophysiological version of the task, event-related potentials (ERPs) showed earlier latencies for P1 and N1 components at posterior locations to between- relative to within-category deviants, providing novel evidence for early perceptual processes on color CP. Enhanced P2 and P3 waves were also found for between- compared to within-category stimuli, indicating a role for later post-perceptual processes.
