Perception of parental socialization strategies in adoptive and non-adoptive families

Although parental socialization styles have been investigated in recent years, little research has been carried out on the issue of parental styles in adoptive families. The aim of this research is to analyse parental styles both from the point of view of the parents and of adopted and non-adopted adolescents, taking as covariables the adolescents' sex and age. The sample was made up of 55 adopted adolescents (20 boys and 35 girls with an age range of 11-17 years) and their 55 adoptive parents, and 402 non-adopted adolescents (200 boys and 202 girls with an age range of 11-17 years), and their 258 parents. Two scales evaluated parental styles: the Affect Scale and the Rules and Demands Scale. The results showed that, both from the point of view of the parents and of the adolescents, adoptive families are more affective, communicative and inductive, and less critical and indulgent than non-adoptive families. No differences were found between adopted and non-adopted adolescents on the Parents' Rigidity Scale.     

Bilingual aphasia and language control: A follow-up fMRI and intrinsic connectivity study

In a world that is becoming more multilingual, bilingual aphasia is a clinical problem with a major clinical impact. However, at present we lack causal explanations of the many features of recovery patterns and there is no consensus about the language in which the patient should receive speech therapy. Further advance requires an understanding of the dynamics of recovery. In a novel longitudinal, single-case study, we combine fMRI and dynamic causal modeling to examine the effects of specific language treatment for picture naming on the representation and control of language areas during the course of recovery. Improved performance in the treated language was associated with increased activation in language areas. Consistent with theoretical expectations, causal modeling indicated increased connectedness of the control and language networks for the treated language. This functional approach holds great promise for investigating recovery patterns and the effects of specific language treatment in bilingual aphasic patients.     

Is the truth in the details? Extended narratives help distinguishing false “memories” from false “reports”

The present study examined the effects of fantasy proneness on false "reports" and false "memories", of existent and non-existent footage of a public event. We predicted that highly fantasy prone individuals would be more likely to stand by their initial claim of having seen a film of the event than low fantasy prone participants when prompted for more details about their experiences. Eighty creative arts students and 80 other students were asked whether they had seen CCTV footage preceding the attack on Swedish foreign minister Anna Lindh up to, and including, non-existent footage of the actual moment of the attack. If affirmative, they were probed for extended narratives of what they claimed to have seen. Overall, 64% of participants provided a false "report" by answering yes to the initial question. Of these, 30% provided no explicit details of the attack, and a further 15% retracted their initial answer in their narratives. This left 19% of the sample who appeared to have false "memories" because they provided explicit details of the actual moment of the attack. Women scored higher than men and art students scored higher than other students on fantasy proneness, but there was no effect on levels of false reporting or false "memory". Memories were rated more vivid and clear for existent compared to non-existent aspects of the event. In sum, these data suggest a more complex relationship between memory distortions and fantasy proneness than previously observed.     

Word fluency performance and strategies in children with cochlear implants: age‐dependent effects?

Löfkvist, U., Almkvist, O., Lyxell, B. & Tallberg, I.‐M. (2012). Word fluency performance and strategies in children with cochlear implants: age‐dependent effects? Scandinavian Journal of Psychology 53, 467–474. Word fluency was examined in 73 Swedish children aged 6–9 years divided into two age groups, 6–7 and 8–9 years; 34 deaf children with cochlear implants (CI) (15 girls/19 boys) and 39 age‐matched children with normal hearing (NH) (20 girls/19 boys). One purpose was to compare the ability to retrieve words in two different word fluency tasks; one phonemically based (FAS letter fluency) and one semantically based (animal fluency). A second purpose was to examine retrieval strategies in the two tasks by conducting an analysis of clustering and switching of word sequences. In general we found that age was an important factor for word fluency ability, in both the CI and the NH groups. It was also demonstrated that children with CI aged 8–9 years retrieved significantly fewer words and used less efficient strategies in the retrieval process, especially on the phonemically based task compared to children with NH of the same ages, whereas children 6–7 years performed similarly in both groups regarding number of retrieved words and use of strategies. The results are discussed with respect to factors such as age differences in performance for children with CI, especially for the phonemically based task.     

Validation of eating disorder examination questionnaire (EDE-Q)--Spanish version--for screening eating disorders

This research examines the internal consistency, convergent validity, and sensitivity, specificity, and positive and negative predictive value of the Spanish version of the Eating Disorder Examination-Self-Report Questionnaire (S-EDE-Q), as a screening questionnaire for eating disorders (ED) in a community sample. Participants were 1543 male and female Spanish-speaking students (age range: 12-21 years), who volunteered to complete the S-EDE-Q and the EAT-40. The Spanish version of the Eating Disorders Examination (S-EDE) interview, 12th edition, was administered to 602 of the students. Acceptable internal consistency for the four subscales of the S-EDE-Q was obtained (alpha > or = .74). Corrected point-biserial correlation performed with the 22 items included in the S-EDE-Q subscales showed acceptable values for all the items. The EAT-40 Dieting subscale correlated highly and positively with the four S-EDE-Q subscales (r > or = .70). Acceptable results in sensitivity, specificity, and positive and negative predictive value when compared with the EDE were found. Correlation between S-EDE and S-EDE-Q diagnoses was positive and significant. Overall, results support the psychometric adequacy of the S-EDE-Q as a screening questionnaire for ED in community samples.     

From Incubation to Insight: Working Memory and the Role of the Cerebellum

An experiment involving 90 students in the 1st, 3rd, and 5th grades investigated how visual examples and grade (our surrogate for age) affected variability in a drawing task. The task involved using circles as the main element in a set of drawings. There were two examples: One was simple and single (a smiley face inside a circle); the other, complex and dual (a fishbowl extending outside a circle and a bicycle using two circles). There were significant effects of both example and grade on variability. Between-grades, 3rd and 5th graders were more variable than 1st graders with the complex (but not the simple) set of examples. Within-grades, 3rd and 5th graders were more variable with the complex (compared to the simple) set of examples. First graders' variability levels did not change with examples. The discussion focuses on how examples have and should be used to increase variability in drawings of both younger and older children.     

Neural connectivity patterns underlying symbolic number processing indicate mathematical achievement in children

In early childhood, humans learn culturally specific symbols for number that allow them entry into the world of complex numerical thinking. Yet little is known about how the brain supports the development of the uniquely human symbolic number system. Here, we use functional magnetic resonance imaging along with an effective connectivity analysis to investigate the neural substrates for symbolic number processing in young children. We hypothesized that, as children solidify the mapping between symbols and underlying magnitudes, important developmental changes occur in the neural communication between the right parietal region, important for the representation of non‐symbolic numerical magnitudes, and other brain regions known to be critical for processing numerical symbols. To test this hypothesis, we scanned children between 4 and 6 years of age while they performed a magnitude comparison task with Arabic numerals (numerical, symbolic), dot arrays (numerical, non‐symbolic), and lines (non‐numerical). We then identified the right parietal seed region that showed greater blood‐oxygen‐level‐dependent signal in the numerical versus the non‐numerical conditions. A psychophysiological interaction method was used to find patterns of effective connectivity arising from this parietal seed region specific to symbolic compared to non‐symbolic number processing. Two brain regions, the left supramarginal gyrus and the right precentral gyrus, showed significant effective connectivity from the right parietal cortex. Moreover, the degree of this effective connectivity to the left supramarginal gyrus was correlated with age, and the degree of the connectivity to the right precentral gyrus predicted performance on a standardized symbolic math test. These findings suggest that effective connectivity underlying symbolic number processing may be critical as children master the associations between numerical symbols and magnitudes, and that these connectivity patterns may serve as an important indicator of mathematical achievement.     

Use of kind information for object individuation in young domestic chicks

In this paper, we studied the ability of newborn chicks to use kind information (sortal objects) provided by social and food attractors to determine the number of distinct objects present in an event (object individuation). Newly hatched chicks were reared with five imprinting objects and were fed mealworms. Chicks’ spontaneous tendency to approach the larger group of items was exploited. At test, on day 2 post-hatching, chicks observed two events in which objects, differing in kind, were each hidden behind one of two identical screens. Approaching either screen was considered a preferential choice. In Experiment 1, chicks presented with two social versus two food attractors did not exhibit any preference. In contrast, in Experiment 2, when chicks saw two different attractors (one social and one food) hidden behind a screen and one attractor hidden twice (i.e. moved back and forth two times) behind the other screen, they spontaneously approached the two different attractors rather than the single one seen twice. An explanation based on the preference for the more varied set was ruled out in Experiment 3: chicks did not preferentially choose between two different versus two identical objects when both groups were simultaneously presented. Results suggest for the first time that a non-human species uses kind information for individuating objects in a cross-basic-level contrast (i.e. food and social items) with minimal experience. As social and food stimuli differ in property as well as in kind information, the alternative explanation accounting for use of property information alone is also discussed.     

The moderating role of pessimism in the association between retrospective relational peer victimization,interpersonal risk factors,and suicide ideation

Peer victimization (PV) is a serious concern for youth and is associated with subsequent suicide ideation in young adulthood. The interpersonal theory of suicide may provide a framework for understanding suicide ideation in this population. Specifically, thwarted belongingness (TB) and perceived burdensomeness (PB) have been significantly associated with suicide ideation among young adults with a history of peer victimization. Additionally, the personality trait of pessimism is associated with elevated suicide ideation. Thus, this study tested the association between self-reported frequency of retrospective relational (i.e., verbal and indirect) PV in primary and secondary school, thwarted interpersonal needs (TB and PB), and current suicide ideation, as well as how these relations may vary based on current pessimism. Participants were 330 undergraduate students. Nonparametric bootstrap moderated mediation procedures were used to test hypotheses. Results indicated significant indirect effects of frequency of retrospective relational PV and suicide ideation through PB and TB. Contrary to predictions, results did not indicate significant moderated mediation; however, the association between PB and suicide ideation was stronger at lower pessimism levels. We also provide supplemental analysis with optimism as the moderator. These findings suggest that clinicians may consider targeting TB, PB, as well as pessimism and optimism among those with a history of relational PV when assessing and intervening on current suicide ideation. Implications, limitations, and future directions are further discussed.
