Action representation deficits in adolescents with developmental dyslexia

Developmental dyslexia (DD), a severe and frequent disorder of reading acquisition, is characterized by a diversity of cognitive and motor deficits whose interactions still remain under debate. Although deficits in the automatization of sensorimotor control have been highlighted, internal action representation allowing prediction has never before been investigated. In this study, we considered action representation of 18 adolescents with pure DD and 18 age-matched typical readers. Participants actually and mentally performed a visually guided pointing task involving strong spatiotemporal constraints (speed/accuracy trade-off paradigm). While actual and mental movement times of typical readers were isochronous and both conformed to Fitts’ law, the movement times of dyslexics differed between conditions, and only the actual movement times conformed to Fitts’ law. Furthermore, the quality of motor imagery correlated with word reading abilities. This suggests that the process of action representation is impaired in pure DD and supports the sensorimotor perspective of DD. Theoretical implications are discussed.     

Validity of the multiple-stimulus without replacement preference assessment for edible items

Studies have shown that the multiple-stimulus without replacement (MSWO) preference assessment is an effective assessment format for identifying preferred items. However, it is possible that factors other than reinforcer quality might influence selections by some individuals when the MSWO array consists of edible items. The validity of the MSWO results was evaluated by comparing items identified as most and least preferred by the MSWO assessment in a concurrent-schedule (CS) format. Varying edible items were used in each study. The MSWO format accurately identified the higher quality edible item for most participants across studies (76%); however, the MSWO format did not predict the highest quality edible item in the CS assessment for 20% to 30% of participants in each study.

“Feeling my Sister’s Pain”: Perceived Victim Suffering Moderates the Impact of Sexualized Music Videos on Fijian Women’s Responses to Men’s Intimate Partner Violence against Women

To better understand how sexualized music videos affect women’s responses to intimate partner violence (IPV), we examined the role of individual variability in perceived victim pain and perceived victim culpability in moderating and mediating (respectively) the priming effects of sexual music videos on women. Female Fijian college students (n?=?243) were randomly assigned to one of three viewing conditions: stereotyped sexual music videos, non-stereotyped/non-sexual music videos, or neutral videos. All participants then read a portrayal of a male-toward-female IPV episode and their perceptions of the female victim and male perpetrator were assessed. Only women who minimized the victim’s pain were adversely affected by exposure to the stereotyped sexual videos. Specifically, for women who perceived low victim pain, those in the stereotyped video condition perceived the victim as more culpable and reported greater perpetrator-directed favorable responding than those in the other two conditions. For these women who perceived low victim pain, perceptions of victim culpability mediated the impact of video type on perpetrator-favorable responding. The findings help us better understand susceptibility to the negative impact of stereotypical sexual videos and highlight areas, such as emphasizing the suffering of victims and reducing myths about victim culpability, which may be worthy of particular emphasis in interventions.

     

The role of epistemic and social characteristics in children’s selective trust: Three meta‐analyses

Over the last 15 years, researchers have been increasingly interested in understanding the nature and development of children’s selective trust. Three meta‐analyses were conducted on a total of 51 unique studies (88 experiments) to provide a quantitative overview of 3‐ to 6‐year‐old children’s selective trust in an informant based on the informant’s epistemic or social characteristics, and to examine the relation between age and children’s selective trust decisions. The first and second meta‐analyses found that children displayed medium‐to‐large pooled effects in favor of trusting the informant who was knowledgeable or the informant with positive social characteristics. Moderator analyses revealed that 4‐year‐olds were more likely to endorse knowledgeable informants than 3‐year‐olds. The third meta‐analysis examined cases where two informants simultaneously differed in their epistemic and social characteristics. The results revealed that 3‐year‐old children did not selectively endorse informants who were more knowledgeable but had negative social characteristics over informants who were less knowledgeable but had positive social characteristics. However, 4‐ to 6‐year‐olds consistently prioritized epistemic cues over social characteristics when deciding who to trust. Together, these meta‐analyses suggest that epistemic and social characteristics are both valuable to children when they evaluate the reliability of informants. Moreover, with age, children place greater value on epistemic characteristics when deciding whether to endorse an informant’s testimony. Implications for the development of epistemic trust and the design of studies of children’s selective trust are discussed.     

Active power and causal flow in aristotle's theory of vision

Aristotle's theory of vision has been characterized as naive, incommensurate with his theory of audition, and of historical interest only. This view is based on an analysis which fails to acknowledge the role of the concepts acting upon and active power in the theory. The meaning of these terms and the role Aristotle assigned them in vision and in sensation generally is demonstrated. It is argued that with the inclusion of these concepts (1) the theory of vision is sufficiently sophisticated and modern to be more than comparable with more recent perceptual theorizing, and (2) the overall integrity of Aristotle's sensory philosophy is preserved. It is further argued that given the cohesiveness and comprehensiveness of Aristotle's psychological works, more attention should be given them by modern psychologists.     

Processing speed in the 1st year of life: a longitudinal study of preterm and full-term infants

Processing speed was assessed at 5, 7, and 12 months in full-term and preterm infants (birth-weight < 1,750 g). Speed was gauged directly in a new task by presenting infants with a series of paired faces, one that remained the same across trials and one that changed; trials continued until infants showed a consistent novelty preference. At all ages, preterms required about 20% more trials and 30% more time than full-terms to reach criterion. Among preterms, slower processing was associated with greater medical risk (e.g., respiratory distress syndrome). Developmental trajectories for speed (and attention) were similar for both groups. Thus, the deficits in processing speed previously found for preterms in childhood are already present in the 1st year of life.     

Attachment,mastery, and interdependence: a model of parenting processes

A democratic nation needs an interdependent citizenry who are not only competent but who also can live together cooperatively with an eye toward what will benefit the whole as well as the self. In this article, the concept of interdependence is adopted as the central goal of parenting. The Parenting Processes Model is then presented, specifying how caregivers help children develop this interdependence. This work draws upon and integrates the work of a number of theoreticians, researchers, and clinicians, with the central focus on the work of John Bowlby, Alfred Adler, and Lev Vygotsky.
