Perception and its objects

Early modern empiricists thought that the nature of perceptual experience is given by citing the object presented to the mind in that experience. Hallucination and illusion suggest that this requires untenable mind-dependent objects. Current orthodoxy replaces the appeal to direct objects with the claim that perceptual experience is characterized instead by its representational content. This paper argues that the move to content is problematic, and reclaims the early modern empiricist insight as perfectly consistent, even in cases of illusion, with the realist contention that these direct objects of perception are the persisting mind-independent physical objects we all know and love.

Exploring mental-state reasoning as a social-cognitive mechanism for social loafing in children

The authors explored mental-state reasoning ability among 72 preschoolers (ages 3-5 years) as a possible developmental mechanism for the well-known social loafing effect: diminished individual effort in a collaborative task. The authors expected that older children would outperform young children on standard mental-state reasoning tests and that they would display greater social loafing than younger children. In addition, we hypothesized that the ability to infer the mental states of others would be predictive of social loafing, but that the ability to reason about one's own knowledge would not. The authors gave children three standard false-belief tasks and participated in a within-subjects balloon inflation task that they performed both individually and as part of a group. Results indicated that 3-year-olds performed significantly below older preschoolers on mental-state reasoning tasks. Only 4- and 5-year-olds displayed diminished individual effort. Multiple regression analysis indicated that only the ability to reason about others' false beliefs accounted for a significant amount of variance in social loafing; age (in months) and own false-belief reasoning did not. The authors discussed theoretical and pedagogical implications.     

Can Virtuous Actions be Both Habitual and Rational?

Virtuous actions seem to be both habitual and rational. But if we combine an intuitive understanding of habituality with the currently predominant paradigm of rational action, these two features of virtuous actions are hard to reconcile. Intuitively, acting habitually is acting as one has before in similar contexts, and automatically, that is, without thinking about it. Meanwhile, contemporary philosophers tend to assume the truth of what I call the reasons theory of rational action, which states that all rational actions are actions for reasons. Whilst interpretations of this phrase are disputed, I argue that neither of the two leading views – which I call reasons internalism and reasons externalism – makes room for habitual actions to count as actions for reasons; by the reasons theory, they cannot be rational either. I suggest one way of effecting the reconciliation which, whilst it allows us to keep the reasons theory, requires us to conceive of reasons as even more radically external than current externalists believe them to be.     

The L-type calcium channel blocker nifedipine impairs extinction, but not reduced contingency effects, in mice

We recently reported that fear extinction, a form of inhibitory learning, is selectively blocked by systemic administration of L-type voltage-gated calcium channel (LVGCC) antagonists, including nifedipine, in mice. We here replicate this finding and examine three reduced contingency effects after vehicle or nifedipine (40 mg/kg) administration. In the first experiment, contingency reduction was achieved by adding USs to the training protocol (degraded contingency), a phenomenon thought to be independent of behavioral inhibition. In the second experiment, contingency reduction was achieved by varying the percentage of CS-US pairing, a phenomenon thought to be weakly dependent on behavioral inhibition. In the third and fourth experiments, contingency reduction was achieved by adding CSs to the training protocol (partial reinforcement), a phenomenon thought to be completely dependent on behavioral inhibition. We found that none of these reduced contingency effects was impaired by nifedipine. In a final experiment, we found that extinction conducted 1 or 3 h post-acquisition, but not immediately, was LVGCC-dependent. Taken together, the results suggest that reduced contingency effects and extinction depend on different molecular mechanisms and that LVGCC dependence of behavioral inhibition develops with time after associative CS-US learning.     

National Stuttering Association members' opinions about stuttering treatment

As stuttering support groups, such as the National Stuttering Association (NSA), have gained prominence and visibility, it has become increasingly important for speech-language pathologists (SLPs) to learn about the people who participate in such groups. This article presents results of a brief survey completed by 200 members of the NSA to examine the opinions of support group members regarding the field of speech-language pathology and stuttering treatment options. Results indicate that NSA members hold a variety of opinions, both positive and negative, about the resources available to them. Findings highlight a number of ways in which SLPs can work with stuttering support groups, both to learn more about the needs of people who stutter and also to provide needed information about treatment options that are available for people who stutter. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to describe (1) the role of support groups in stuttering treatment; (2) the people who are members of the NSA; and (3) their opinions about various issues related to stuttering and its treatment.     

Longitudinal analysis of midlife generativity, intergenerational roles, and caregiving

Items from the California Adult Q-Sort (CAQ) were used to assess psychosocial generativity (E. H. Erikson, 1950) in a sample of educated women at midlife. CAQ scores measured at age 43 demonstrated convergent validity with an inventory measure of generativity assessed at age 53. According to other longitudinal analyses, women who attained a generative stance at age 43 reported greater investment 10 years later in intergenerational roles (e.g., daughter, mother) but not nonintergenerational ones (e.g., friend, sister). Generative women also reported less subjective burden in caring for aging parents and more knowledge about community elder care programs. Further evidence suggests that participants felt embedded in a reciprocal caregiving network in which they themselves were the recipients of care.     

Using a Naturalistic Sport Context to Train Social Skills in Children

ABSTRACT

Researchers have utilized sports activities to deliver social skills training (SST) programs to children. Using a multiple-baseline across behaviors design, we examined whether a brief SST program delivered during a soccer camp would increase social skills and athletic competencies. Each participant’s self-concept, and his interest in soccer were evaluated. Results suggest that the SST procedure effectively increased targeted social skills. Further, participants reported increased interest in soccer and higher overall self-concept. Our results suggest that similar effects can be achieved in a relatively short, but intense, camp that utilizes SST and sports-skill training components. Limitations and implications are discussed.
