Sequence-sensitive exemplar and decision-bound accounts of speeded-classification performance in a modified Garner-tasks paradigm

Among the most fundamental results in the area of perceptual classification are the “correlated facilitation” and “filtering interference” effects observed in Garner’s (1974) speeded categorization tasks: In the case of integral-dimension stimuli, relative to a control task, single-dimension classification is faster when there is correlated variation along a second dimension, but slower when there is orthogonal variation that cannot be filtered out (e.g., by attention). These fundamental effects may result from participants’ use of a trial-by-trial bypass strategy in the control and correlated tasks: The observer changes the previous category response whenever the stimulus changes, and maintains responses if the stimulus repeats. Here we conduct modified versions of the Garner tasks that eliminate the availability of a pure bypass strategy. The fundamental facilitation and interference effects remain, but are still largely explainable in terms of pronounced sequential effects in all tasks. We develop sequence-sensitive versions of exemplar-retrieval and decision-bound models aimed at capturing the detailed, trial-by-trial response-time distribution data. The models combine assumptions involving: (i) strengthened perceptual/memory representations of stimuli that repeat across consecutive trials, and (ii) a bias to change category responses on trials in which the stimulus changes. These models can predict our observed effects and provide a more complete account of the underlying bases of performance in our modified Garner tasks.     

Comparative Religious Ethics Among the Ruins

This is a response to the recent essay by Elizabeth M. Bucar and Aaron Stalnaker on “Comparative Religious Ethics as a Field of Study.” I clarify my earlier positions on method and virtue in comparative religious ethics and try to respond to some of the issues that Bucar and Stalnaker raise in regard to my arguments specifically and the field more generally. I argue that while we need not measure the practical impact of scholarly work in comparative religious ethics purely in terms of political or social action, I nevertheless worry that defining the goals of comparative inquiry in terms of the production of bewilderment, intellectual vertigo, or skeptical questions can lead to impressionistic or therapeutic methodological norms. In a similar vein, I refine my earlier position on externalism that acknowledges the impossibility of a purely externalist approach but also notes the desirability of coming to understand others “in their own terms” prior to engaging in the process of transmutation. I also question Bucar and Stalnaker's pessimism about the potential of producing “rigorously convincing ethical theory from the lived experience of regular folk,” suggesting that perhaps we are working with different conceptions of the sociology of knowledge. Finally, I consider whether we are currently in the midst of an epistemological crisis and conclude with some reflections on the rationality of the craft of comparative religious ethics.     

The corona crisis unmasks prevailing social ideologies

This essay contrasts two visions of selfhood: the buffered, autonomous self, and the flexible, resonant self. The autonomous self, while robustly assertive and active, seeks to insulate itself from threats, thereby robbing it of vital connections to other selves and to nature. The resonant self, in contrast, risks more by standing in fluid relationships of resonance and dissonance with its social and natural environments. While the two stand in tension, a baptismal theology entails both elements of a sheltered self and a resonant self that remains flexible and responsive to the ups and downs of human experience. Conversely, even a secular-minded person will have access to important zones of resonance.     

Implementation of a brief early intervention in times of socio-economic crisis: effects on parental stress

The paper investigates the effect of brief early intervention on parental stress in the midst of a socio-economic crisis, such as the one that struck Greece in the past decade. During this period, a psychoanalytically oriented prevention programme with parents and their infants/young children, named ‘Early Intervention Programme’, was designed and implemented in the Department of Child Psychiatry at ‘Aghia Sophia’ Children’s Hospital in Athens, Greece. The families that attended the programme were asked to participate in a research study regarding its effectiveness; data were collected from 102 mothers and 73 fathers. This paper presents the statistical findings regarding parental stress, mainly because it is a factor that has systematically been shown to negatively influence several aspects of a child’s development, but also because our hypothesis was that parental stress would be influenced by the negative external conditions. The results showed that both mothers’ and fathers’ stress levels were high before their participation to the programme (with fathers’ Total Stress scores falling within the clinical range), while they decreased to a statistically significant level after the completion of the programme. These findings are discussed in conjunction with some illustrative clinical material. Based on these, it is argued that the implementation of a psychoanalytically oriented brief early intervention programme with parents and infants/young children can alleviate parental stress, and thus support the parental capacity to efficiently deal with the high demands of early development, even in periods of economic crisis where the tensions for young parents are significant and the available mental health resources are scarce.     

Can the Media Help Women Be Better at Math? Stereotype Threat,Selective Exposure,Media Effects,and Women's Math Performance

This study examines women's media selections when under the gender–math stereotype threat and the subsequent media effects on their math performance through the lens of the Selective Exposure Self‐ and Affect‐Management (SESAM) model, mood management theory, and social comparison theory. Female college students were randomly assigned to the stereotype threat condition or the control condition; then, they selectively browsed magazine pages showing female role models in stereotypical domains (beauty or family) and counterstereotypical domains (career or science) before taking the math test. The results show that women spent more time on career magazines when under threat, and this selective exposure's effect on their math performance was moderated by their assimilation to the role models.     

Ad hominem rhetoric in scientific psychology

Ad hominem discourse is largely prohibited in scientific journals. Historically, this prohibition restricted the dissemination of ad hominem discussion, but during the last decade, blogs and social media platforms became popular among researchers. With the use of social media now entrenched among researchers, there are important questions about the role of ad hominems. Ad hominems and other forms of strong criticism became particularly evident in online discussions associated with the recent replication crisis in psychology. Here, these discussions, and a few incidences of ad hominems in journal articles, are situated in the broader history of science. It is argued that explicit codes of conduct should be considered to curb certain kinds of ad hominem comments in certain fora, but that some ad hominem discussions have an important role to play in a healthier science.     

Telling the Truth About Power

SUMMARY

In this culture, those in power do not usually talk about it and the rest of us tend not to recognize it either. A similar situation exists in therapy, where the therapist herself may not be aware of her own power-over tactics. This article suggests methods that may help therapists to acknowledge their power and also to change from power-over actions to mutually empowering relationships. From this line of thinking, there follows an exploration of altering the concept of boundaries in therapy into mutually constructed agreements between patient and therapist. This article was presented at the Summer Training Institute of the Jean Baker Miller Training Institute, June, 2003.
