Movement duration does not affect automatic online control

Pisella et al. (2000) have shown that fast aiming movements are automatically modified on-line in response to a change in target position. Specifically, when a movement is less than 300 ms in duration the reach is completed to a target’s new location even when one never intended to respond to the target jump. In contrast, when movements are slower, the reach is completed according to instructions. At present, it is unclear if it is possible for one’s intentions to guide the initial stages of these slow movements. To determine if the intentional control mechanism can guide the initial stages of a slow aiming movement, participants aimed to targets that could jump at movement onset, with a slow and very slow movement time goal. In particular, participants were to point towards (“pro-point”) or away from (“anti-point”) the target jump, with a movement time goal of 500 or 1200 ms. Results showed that in the anti-point condition, movement trajectories first deviated in the same direction as the target jump, followed by a response in the intended (opposite) direction. This suggests that while movement outcome is controlled by the intentional system, even in these slow aiming movements the automatic system is engaged at movement onset.     

Examining the Relationship Between Female Parents with Low Perceived Control and Adolescent Child Stress

Adolescence is a stressful time for many children. Changes in their environment or changes in social situations are some typical stressors that an adolescent child might encounter. Interactions with parents can also be stressors for a child. Previous research has shown that a risk factor for a parent using harsh parenting techniques is perceived control. Parents who have low perceived control are at a higher risk to engage in physical parenting techniques or child abuse. This study included 198 middle school students and their female parent or guardian pairs (296 total participants), with the adolescent participants ranging in age from 10- to 14-years-old. The adult participants were evaluated for their level of perceived control and the adolescent participants were evaluated for their level of perceived stress. Parents who perceived themselves as having a low amount of control over their child’s behavior (low ACF), were linked with their child having a high level of perceived stress. This effect was found only for the 14-year-old participants. Implications of results and areas of further research are suggested. It is possible that as a child gets older and enters puberty, the parent of the child feels as if they are losing control over their child and, as a result, resort to more forceful parenting techniques to regain control.     

Predictors of timed picture naming in Persian

In this study, we report normative data by native Persian speakers for concept familiarity, age of acquisition (AoA), imageability, image agreement, name agreement, and visual complexity, as well as values for word frequency, word length, and naming latency for 200 of the colored Snodgrass and Vanderwart (Journal of Experimental Psychology: Human Learning and Memory 6:174-215, 1980) pictures created by Rossion and Pourtois (Perception 33:217-236, 2004). Using multiple regression analysis, we found independent effects of name agreement, image agreement, word frequency, and AoA on picture naming by native Persian speakers from Iran. We concluded that the psycholinguistic properties identified in studies of picture naming in many other languages also predict timed picture naming in Persian. Normative data for the ratings and picture-naming latencies for the 200 Persian object nouns are provided as an Excel file in the Supplemental materials.     

Through Thick and Thin with Ned Block: How <Emphasis Type="Italic">Not</Emphasis> to Rebut the Property Dualism Argument

In “Max Black’s Objection to Mind–Body Identity,” Ned Block seeks to offer a definitive treatment of property dualism arguments that exploit modes of presentation. I will argue that Block’s central response to property dualism is confused. The property dualist can happily grant that mental modes of presentation have a hidden physical nature. What matters for the property dualist is not the hidden physical side of the property, but the apparent mental side. Once that ‘thin’ side is granted, the property dualist has won. I conclude that although Block is wrong to think that the property dualist must argue for so-called thin mental properties, Block, and the physicalist, are able to resist property dualism. But any attempt to bolster this resistance and do more than dogmatically assert the crucial identity runs a serious risk of undermining the physicalism it is meant to save.

Tabular asterisks, Paul Meehl, and looking at the data

Three of Meehl’s major concerns are examined in this summary. They are the problem of null-hypothesis testing as a strategy, the central significance of heterogeneity in human behavior, and the over-dependence on rating scales with their inherent lack of precision.     

Retrospective spiritual narratives: exploring recalled childhood and adolescent spiritual experiences

This paper draws on a collection of retrospective narratives of childhood and adolescent spiritual experiences to explore the qualities and characteristics of the spirituality of the young. They recall a range of spiritual experiences that touch on death, mortality, visions, and perceptions and connections beyond the self. Their experiences include varying intensities of emotion and invoke a range of responses in them and others. The paper considers the social, emotional and familial context of these early life experiences and their impact on spiritual experience and the possibility/impossibility and freedom/lack of freedom to express, and integrate spirituality.     

Mathematics—a Critical Filter for STEM-Related Career Choices? A Longitudinal Examination among Australian and U.S. Adolescents

Although women have made progress in entering scientific careers in biology, they remain underrepresented in mathematically intensive fields such as physics. We investigated whether gender differences in mathematics motivation and socialisers’ perceptions impacted choices for diverse STEM careers of varying mathematical intensity. Drawing on expectancy-value theory, we tested structural equation models in which adolescents’ preferred careers related to each of physics, biology, chemistry, and mathematics were predicted by prior mathematical performance, motivations, and mothers’ perceptions. We explored potential differences in gendered processes of influence using multigroup models. Samples were 331 Australian adolescents followed from 9th to 11th grade in 1998 and 277 U.S. adolescents from 9th to 12th grade in 2009–10. In both samples female adolescents preferred biological careers more than males did; male adolescents preferred physics-related careers and also mathematical careers in the Australian sample. Mothers’ perceptions were important to female and male adolescents’ mathematics motivations; gendered motivations were more evident in the Australian sample. Mathematics interest played the strongest role in male adolescents’ preferred careers, whereas actual or perceived mathematical achievements were most important for females, demonstrating the impacts of mathematical motivations on preferences for diverse STEM careers.
