FEMINIST IDENTITY, GENDER TRAITS, AND SYMPTOMS OF DISTURBED EATING AMONG COLLEGE WOMEN

This study explored relationships among feminist identity, gender traits, and symptoms of disturbed eating. Seventy-one college women completed the following: weight-related questions, Feminist Identity Development Scale, Personal Attributes Questionnaire, Figure Rating Scale, and Eating Disorders Inventory. Identification with feminist values negatively correlated with body dissatisfaction, bulimic symptoms, and feelings of ineffectiveness. Identification with stereotypical masculine traits was inversely related to perfectionist tendencies and feelings of ineffectiveness, but was unrelated to body concerns. These results suggest factors promoting body dissatisfaction and disturbed eating may have less impact on college women identifying with feminist values, such as commitment to nonsexist roles and personal empowerment.     

Vibrotactile masking: A comparison of psychophysical procedures

The amounts of ipsilateral and contralateral masking obtained with a modified psychophysical procedure were compared for vibratory stimuli presented to different body loci. Results of a combined forced-choice localization task and a forced-choice detection task were similar to the results obtained in previous investigations which employed method of limits and two-alternative, temporal forced-choice procedures, respectively. Ipsilateral maskers produced similar amounts of masking in both the detection and localization tasks for fingertip and arm test sites. Contralateral maskers resulted in considerably more masking in the localization task than in the detection task for both fingertip and arm test sites. When large longitudinal distances were introduced between the test stimulus and masker, little masking was evident in either the localization or detection task. It was concluded that the differences in the amount of ipsilateral and contralateral masking obtained with different psychophysical procedures reflect different effects of a masker on the detectable attributes of a test stimulus. Implications of these results for the study of multiple tactile perception were discussed.     

Authors who have an impact on candidates' training

The authors consider the influence that a sense of geographical and cultural ties of candidates from different regions has on their theoretical interests. They question the way that this is taken into consideration in psychoanalytic training. The function of theory, both in terms of its transmission and the creation of new knowledge, is explored from this perspective. The results of an Internet survey are presented. The candidate sample for this survey (N = 250) was drawn from Europe, Latin America and North America, and candidates were asked to indicate their degree of interest for each of the 55 authors in a given list. The results showed that there were significant differences in the areas of theoretical interest of the candidates depending on the geographical region. Furthermore, what is also significant is how these differences in areas of theoretical interest were linked to those authors who had developed their work in the same geographical region as the candidates. These differences are shown to be connected to the candidates' sense of regional belonging. Data are also presented about which authors have the greatest impact in a given region, along with the influence values of the authors in relation to each one of the regions. Finally, the candidates' interest in each of the authors is specified in terms of a general mean rank and a regional mean rank, thus showing which authors candidates find most interesting in each of the regions. The study concludes by arguing that the results of the investigation enable us to question how psychoanalytic theory is transmitted, and, more specifically, how it is transmitted within institutions at a regional level. It is also suggested that the means be found to uncover the inconsistencies linked to cultural ties. It is proposed that further research be conducted to look more deeply into how cultural differences play a part in the different theoretical languages in the training of psychoanalysts.     

Individual differences in motor development during early childhood: An MEG study

In a previous study, we reported the first measurements of pre‐movement and sensorimotor cortex activity in preschool age children (ages 3–5 years) using a customized pediatric magnetoencephalographic system. Movement‐related activity in the sensorimotor cortex differed from that typically observed in adults, suggesting that maturation of cortical motor networks was still incomplete by late preschool age. Here we compare these earlier results to a group of school age children (ages 6–8 years) including seven children from the original study measured again two years later, and a group of adults (mean age 31.1 years) performing the same task. Differences in movement‐related brain activity were observed both longitudinally within children in which repeated measurements were made, and cross‐sectionally between preschool age children, school age children, and adults. Movement‐related mu (8–12 Hz) and beta (15–30 Hz) oscillations demonstrated linear increases in amplitude and mean frequency with age. In contrast, movement‐evoked gamma synchronization demonstrated a step‐like transition from low (30–50 Hz) to high (70–90 Hz) narrow‐band oscillations, and this occurred at different ages in different children. Notably, pre‐movement activity (‘readiness fields’) observed in adults was absent in even the oldest children. These are the first direct observations of brain activity accompanying motor responses throughout early childhood, confirming that maturation of this activity is still incomplete by mid‐childhood. In addition, individual children demonstrated markedly different developmental trajectories in movement‐related brain activity, suggesting that individual differences need to be taken into account when studying motor development across age groups.     

Oceans of stimuli: an individual-based model to assess the role of olfactory cues and local enhancement in seabirds’ foraging behaviour

Animal Cognition - Oceans are extremely dynamic environments, which poses challenges for top-predators such as seabirds to find food resources. Yet, seabirds evolved sensorial abilities (olfactory...     

The relationship between maladaptive personality functioning and problematic technology use in adolescence: A cluster analysis approach

In the last two decades, scientific research has explored the problematic use of internet, videogames and mobile phones. However, there is still little consistent knowledge regarding the co-occurrence of problematic technology use and the role of maladaptive personality characteristics in adolescence. The present study aimed to investigate adolescents' styles of technology use with a cluster analysis approach focusing on personality functioning. The sample comprised 408 Italian adolescents (46.3% males) aged 11 to 18 years (M _age = 13.80; SD = 2.08). Data were collected using the Internet Addiction Test, the Videogame Dependency Scale, the Test of Mobile-Phone Dependence Brief Form and the Personality Inventory for DSM5 Brief Form. Results provided a four-cluster solution based on the co-occurrence of problematic technology use. The four clusters were labeled as follows: cluster 1: “Above average internet and mobile-phone use”; cluster 2: “Below average technology use”; cluster 3: “Above average videogame use”; and cluster 4: “Problematic technology use.” Analyses on demographic variables (e.g., gender and age) demonstrated significant differences between the four groups. Adolescents with high levels of problematic technology use reported greater overall personality dysfunction than the other three groups. This finding supported our hypothesis on maladaptive personality functioning in adolescents at risk for addiction. Finally, the Antagonism domain played a specific role in differentiating the severity of adolescents' involvement in technology use. Further studies are needed to confirm our findings and to plan preventive interventions as well as therapeutic treatments.     

Behavioral reactions of newborns to speech-like sounds and their implications for developmental studies

Newborns exposed to a randomized sound battery containing speech-like sounds demonstrated a variety of behavioral reactions reflecting individual differences in personality and organization. Subjects who actively searched the environment for stimuli and showed prolonged vigilance episodes scored in the 90th percentile on the Denver Developmental Test when evaluated at later ages. Subjects who were remarked as inhibiting crying during their exposure to the experimental schedule later were described by their parents as “good” babies, while subjects who vocalized their displeasure during exposure were described far less favorably. These findings may have implications for developmental studies of mother-infant interactions.     

Contingent electric shock (SIBIS) and a conditioned punisher eliminate severe head banging in a preschool child

We report a case in which a Self‐Injurious Behavior Inhibiting System (SIBIS) device and a conditioned punisher were utilized to decrease and maintain suppression of severe head hitting/banging in a preschool child. After an experimental evaluation conducted at the hospital, SIBIS was implemented at home. The originality of this particular SIBIS case study is that programmed and systematic effort at establishing conditioned punishment was included in the intervention. Results indicate that a zero‐level response was rapidly reached, and that the conditioned punisher (i.e. verbal prompt + movement towards the place where SIBIS was kept) was sufficient to maintain treatment effects. Continuous assessment after treatment and formal observation session at 7 months follow‐up revealed that SIBIS could be removed from the natural environment of the child while maintaining a therapeutic effect. These results were interpreted as the effects of the explicit pairing between the delivery of electric stimulations and previously neutral stimuli, which were initially ineffective to elicit any response, or to suppress SIB. Close and extended monitoring during and after treatment failed to reveal the presence of negative side effects associated with SIBIS, whereas a number of positive effects were observed.
