The effect of invalid task parameters on short-term motor memory

Two experiments tested the influence of information from an invalid movement parameter on short-term motor memory for a valid task parameter. Experiment 1 showed that invalid task distance information affected location retention. Experiment 2 showed that invalid task location information affected task distance retention. These findings strengthen the evidence that the codes important for short-term motor retention are affected by a variety of factors within the movement context.     

Word norms for blind and sighted subjects: Familiarity,concreteness, meaningfulness,imageability, imagery modality,and word associations

Normative values for word characteristics were obtained from a sample of 12 college-educated, totally congenitally blind subjects on the basis of their ratings of 161 nouns on scales of familiarity, concreteness, meaningfulness, and imageability. The dominant modality of imagery for each image-evoking word and the strongest word associate for each item also were recorded. The same data were collected for a group of sighted subjects, both to provide a comparison group for the blind subjects and to test the comparability of sighted subjects’ ratings with existing norms. Ratings for sighted subjects correlated strongly with those norms, although the coefficients were slightly higher for ratings of concreteness and imageability than for ratings of familiarity and meaningfulness. Ratings of blind subjects correlated only slightly lower with existing norms for imagery and concreteness, but considerably lower for familiarity and meaningfulness.     

Savoring interventions for mothers of young children: Mechanisms linking relational savoring and personal savoring to reflective functioning

Parenting interventions can improve parenting outcomes, with widespread implications for children's developmental trajectories. Relational savoring (RS) is a brief attachment-based intervention with high potential for dissemination. Here we examine data from a recent intervention trial in order to isolate the mechanisms by which savoring predicts reflective functioning (RF) at treatment follow-up through an examination of the content of savoring sessions (specificity, positivity, connectedness, safe haven/secure base, self-focus, child-focus). Mothers (N = 147, M_age = 30.84 years, SD_age = 5.13; Race: 67.3% White/Caucasian, 12.9% other or declined to state; 10.9% biracial/multiracial, 5.4% Asian, 1.4% Native American/Alaska Native, 2.0% Black/African American; Ethnicity: 41.5% Latina) of toddlers (M_age = 20.96 months, SD_age = 2.50; 53.5% female) were randomized to four sessions of RS or personal savoring (PS). Both RS and PS predicted higher RF, but through different means. RS was indirectly associated with higher RF through greater connectedness and specificity of savoring content, while PS was indirectly associated with higher RF through greater self-focus in savoring content. We discuss the implications of these findings for treatment development and for our understanding of the emotional experience of mothers of toddlers.     

Proprioception and Stimulus-Response Compatibility

Sixteen subjects pressed a left or right key in response to lateralized visual stimuli, in uncrossed (left index finger on left key, right finger on right key) and crossed conditions (left finger on right key and vice versa), with varying finger separations. Visual, tactile, or 'efference copy' cues about relative finger positions were unavailable. Subjects had to press the key on the same side as (compatible group) or opposite side to the stimulus (incompatible group). Separate proprioceptive judgements of the relative finger positions were obtained. Findings of an overall reaction time (RT) advantage for compatible instructions and for uncrossed hands were replicated. With decreasing finger separation the RT advantage for compatible instructions decreased, and the probability of responding with either hand increased. The compatibility effect disappeared completely at the 6-cm crossed position, not at the position that was hardest to judge proprioceptively. This suggests that two forms of neural activation are summed: automatic activation of the anatomically same-side limb, and an integrated, rule-based activation. The results further demonstrate that independent proprioceptive cues from each limb, unassociated with skin contact between the limbs, can mediate the determination of relative position for response selection in stimulus-response compatibility tasks.     

Influences Between Online‐Exclusive,Conjoint and Offline‐Exclusive Friendship Networks: The Moderating Role of Shyness

Prior research has indicated that shy adolescents are more motivated to form friendships online than to form friendships offline. Little is known about whether having friendships found exclusively online may impact self‐esteem and forming offline friendships for these adolescents. This study therefore aimed to provide insight into the moderating role of shyness in the longitudinal interplay between friendships in online and offline contexts in early adolescence. Adolescents and their friends (193 girls, 196 boys; M_age = 13.29) were followed with three consecutive measurements with intervals of eight months. Results showed that particularly for shy adolescents, having friends exclusively online predicted increases in self‐esteem. Self‐esteem, in turn, was found to predict forming more friendships found both offline and online and forming more friendships found exclusively offline. Thus, findings supported the social compensation perspective that shy adolescents may benefit from having friends exclusively online, as these friendships may increase self‐esteem, thereby facilitating the formation of friendships found partially and completely offline.

The Development of Gender Identity,Gender Roles,and Gender Relations in Gifted Students

This article describes the interaction of giftedness with gender identity, gender role, and gender relations. The authors explored ways in which many gifted educational practices are gendered, a model for the development of talent in the context of gender and gender relations, and ways of reducing gender inequities in the realization of potential for both male and female students. Issues that are unique to gifted individuals are aligned with suggestions for counseling interventions.     

Directions of Effects between Adolescent Psychopathic Traits and Parental Behavior

The present study examined the directions of effects between adolescent psychopathic traits and parental behaviors. The data are from a community-based cohort-sequential study. Data were collected annually over 4 years. Participants were 875 adolescents, aged 13-15 at Time 1, and we analyzed their reports of negative and positive parental behavior, delinquency, and psychopathic traits. In results from cross-lagged models, adolescent psychopathic traits predicted changes over time in all of the parental behaviors at nearly all of the time intervals, whereas the prediction from parental behaviors to psychopathic traits was inconsistent across parenting measures and time intervals. These findings suggest that parental behavior is more a reaction than a predictor of psychopathic traits in adolescence.     

Multiple motives for participating in adventure sports

ObjectivesThe purpose of the present study was to explore possible multiple motives for participation in different adventure sports.DesignQualitative design, specifically an inductive-deductive approach informed by reversal theory, was used to analyze participation motivation data.MethodData was collected using the Scanlan Collaborative Interview Method (SCIM; Scanlan, Russell, Wilson, & Scanlan, 2003). Participants were very experienced adventure sport participants involved in riversurfing, mountain biking, kayaking, mountain climbing and hang gliding.ResultsThe results indicated that the participants' motivation was multifaceted. While some participants shared common motives, these were often described in different orders of importance by different participants. The range of motives for adventure sport participation found included: goal achievement, risk taking, social motivation, escape from boredom, pushing personal boundaries and overcoming fear, as well as connecting with the natural environment, and pleasurable kinaesthetic bodily sensations from moving in water or air.ConclusionsThe authors argue for a continuation of a recent trend to provide a more comprehensive picture of the complexities of human motivation for participation in adventure sports which go beyond excitement- or thrill-seeking behaviour.     

Initiating and Sustaining Emotional Abuse in the Coach–Athlete Relationship: An Ecological Transactional Model of Vulnerability

The purpose of this study was to explore the process by which emotional abuse occurs and is often sustained in sport. Methods were established in congruence with the iterative nature of grounded theory. In total, 18 retired elite athletes participated in the study. In-depth semistructured interviews were conducted with each participant, and data were coded using open, axial, and selective coding techniques. Data were interpreted to suggest that the perpetration of emotional abuse in the coach–athlete relationship is closely tied to ambitions and philosophies of athlete development. Based on the findings, an ecological transactional model of vulnerability to emotional abuse in the coach–athlete relationship is proposed. Recommendations are made for future prevention and intervention initiatives.
