Relation of birth weight, maternal intelligence and mother–child interactions to cognitive and play competence of Jamaican two-year old children

The present study assessed whether birth weight, maternal child rearing behaviors, and maternal intelligence combine in an additive or in a non-linear interactive fashion to influence cognitive performance in a sample of 24-month old full-term appropriate and low birth weight Jamaican children. Child cognitive performance was measured using the Griffiths Scale and a laboratory based assessment of the amount of time the child utilized different levels of play behavior. Mothers were videotaped while playing with their children under different instructional conditions and videotapes were coded for 8 maternal interaction patterns. Maternal verbal intelligence was assessed using the PPVT. Results supported the operation of both additive co-action as well as non-linear interactive processes. Birth weight, maternal behaviors toward her child and maternal intelligence predicted child cognitive performance. In addition, low birth weight infants were either less sensitive to facilitative aspects of maternal behaviors and/or more sensitive to maternal inhibitory behaviors than were appropriate birth weight infants. Further, child rearing behaviors of more intelligent mothers were a stronger influence on their child's cognitive performance than those of less intelligent mothers, even when there were no differences in the level of behaviors of more or less intelligent mothers.     

Delay of gratification and delay maintenance by rhesus macaques (Macaca mulatta)

The authors tested the self-control of rhesus macaques by assessing if they could refrain from reaching into a food container to maximize the accumulation of sequentially delivered food items (a delay-maintenance task). Three different versions of the task varied the quantity and quality of available food items. In the first 2 versions, food items accumulated across the length of the trial until a monkey consumed the items. In the 3rd task, a single less-preferred food item preceded a single more-preferred food item. Some monkeys delayed gratification even with relatively long delays between deliveries of items. However, the data suggested that self-control, in the majority of tested individuals, was not significantly different across different task versions and that self-control by macaques was not as prevalent in these tasks as it is in chimpanzees and human children.     

The peak shift in stimulus generalization: equivalent effects of errors and noncontingent shock

Terrace suggested that the peak shift in stimulus generalization occurs because the training stimulus not correlated with reinforcement has become aversive. This hypothesis is plausible in the light of instances where the peak shift is obtained compared with those where it fails to appear. The present experiment attempted to test implications of this hypothesis. Two groups of pigeons learned the same two-stimulus discrimination between colors by different training methods in a free-operant situation. When the discrimination was trained with many errors, a large peak shift was obtained in a subsequent generalization test of wavelength; after discrimination training with few errors, a negligible shift was observed. Half of each group then received noncontingent aversive shock during presentations of the stimulus not correlated with reinforcement in continued discrimination training. After this treatment, the errorless-shock subgroup showed a large peak shift and the error-shock subgroup tended to show a larger shift than before. Nonshocked control groups showed little change in the peak shift. It was concluded that pairing aversive shock with a stimulus not correlated with reinforcement is sufficient to produce or enhance a peak shift. In their effect on the peak shift, aversive shock and large amounts of nonreinforced responding appear to be equivalent.     

Implementation intentions, perfectionism, and goal progress: perhaps the road to hell is paved with good intentions

Two studies explored whether perfectionism moderates the impact of implementation intentions on goal progress. Study 1 used an implementation intention manipulation to examine the effects of these plans in interaction with perfectionism on the progress of New Year's resolutions. Study 2 added a repeated implementation intention condition and monitored affect and monthly goal progress. The results of both studies revealed a significant backfire effect of the implementation intentions on goal progress for participants high on a particular dimension of perfectionism (socially prescribed perfectionism). These perfectionists reported doing significantly worse at reaching their personal goals when they were asked to formulate implementation intentions than when they completed a control exercise. There also was evidence that implementation planning aroused negative affect for socially prescribed perfectionists. These results are the first to suggest that implementation planning may be contra-indicated for individuals with self-critical tendencies.     

Differentiating Adolescent Self-Injury from Adolescent Depression: Possible Implications for Borderline Personality Development

Self-inflicted injury (SII) in adolescence marks heightened risk for suicide attempts, completed suicide, and adult psychopathology. Although several studies have revealed elevated rates of depression among adolescents who self injure, no one has compared adolescent self injury with adolescent depression on biological, self-, and informant-report markers of vulnerability and risk. Such a comparison may have important implications for treatment, prevention, and developmental models of self injury and borderline personality disorder. We used a multi-method, multi-informant approach to examine how adolescent SII differs from adolescent depression. Self-injuring, depressed, and typical adolescent females (n = 25 per group) and their mothers completed measures of psychopathology and emotion regulation, among others. In addition, we assessed electrodermal responding (EDR), a peripheral biomarker of trait impulsivity. Participants in the SII group (a) scored higher than depressed adolescents on measures of both externalizing psychopathology and emotion dysregulation, and (b) exhibited attenuated EDR, similar to patterns observed among impulsive, externalizing males. Self-injuring adolescents also scored higher on measures of borderline pathology. These findings reveal a coherent pattern of differences between self-injuring and depressed adolescent girls, consistent with theories that SII differs from depression in etiology and developmental course.     

Chicago Urban Resiliency Building (CURB): An Internet-Based Depression-Prevention Intervention for Urban African-American and Latino Adolescents

Early preventive interventions for depressive disorders in racial/ethnic minorities may help to reduce lifetime depression outcome disparities by improving developmental trajectories and social outcomes. We describe the development process, intervention and evaluation plan for a culturally adapted, low-cost, primary care/Internet-based depression-prevention intervention (CURB, Chicago Urban Resiliency Building). CURB is culturally adapted for socio-economically disadvantaged African-American and Latino adolescents according to the PEN-3 model of health promotion programs (Airhihenbuwa in Health and culture: beyond the Western paradigm, Sage Publishers, Thousand Oaks, 1995). Based on the idea that health behavior is rooted in culture, the PEN-3 model contains three interdependent dimensions that influence health beliefs and behaviors. Within each dimension are factors (using the acronym PEN) that must be considered about the target culture. Application of the PEN-3 model occurred in 3 phases. In each phase, a dimension of the model was explored and subsequent changes were made to the intervention so as to be more culturally suitable. In the CURB clinical trial, adolescents ages 13–17 will be recruited from wait-lists for mental health services at community health care provider organizations and screened for risk of future depressive disorder in the primary care sites. Adolescents screening positive for persistent depressed mood will be randomly assigned to either the CURB intervention group or the wait-list control group. The study aims are to determine if participants in the CURB intervention group will have lower levels of depressive symptoms and/or a lower cumulative incidence of depressive episodes.     

Aging, body image, and body shape

Participants were 25 older men (M age = 72 years, SD = 10 years) and 27 older women (M age = 71 years, SD = 8 years) who examined multiple line-drawing figures of babies, children, young adults, middle-aged adults, and older adults. Participants picked a number on a Likert-type scale ranging from 1 (very thin) to 9 (very obese) in response to questions including "Which is the most attractive?" and "Which figure would you most like to look like?" They also completed questionnaires about their body image and body shape. In response to the age-specific line drawings (e.g., those depicting older men and older women), older women endorsed thinner figures (e.g., picked smaller numbers) than did men. Likewise, older women reported thinking more about their body shape and appearance than did men and perceived their body image as "a little too big" in comparison with the older men who perceived their body image as "just the right size." However, a breakdown of normal and overweight women in this sample revealed that for some overweight elderly women, obesity could become a satisfactory way of life. Much as with college-aged women, the endorsement of a thinner body image by many of the older adult female participants appeared to persist into late adulthood and suggests that research into body image issues with older adults is relevant and necessary.     

Antecedent Priming at Trace Positions in Children’s Sentence Processing

The present study examines whether children reactivate a moved constituent at its gap position and how children’s more limited working memory span affects the way they process filler-gap dependencies. 46 5–7 year-old children and 54 adult controls participated in a cross-modal picture priming experiment and underwent a standardized working memory test. The results revealed a statistically significant interaction between the participants’ working memory span and antecedent reactivation: High-span children (n = 19) and high-span adults (n = 22) showed evidence of antecedent priming at the gap site, while for low-span children and adults, there was no such effect. The antecedent priming effect in the high-span participants indicates that in both children and adults, dislocated arguments access their antecedents at gap positions. The absence of an antecedent reactivation effect in the low-span participants could mean that these participants required more time to integrate the dislocated constituent and reactivated the filler later during the sentence.     

Relation of positive memory recall count and accessibility with post-trauma mental health

ABSTRACT

Positive memory encoding and retrieval deficits have an empirical relation with several post-trauma outcomes. Drawing from the Contractor et al. model, we examined relations between positive memory characteristics and post-trauma mental health indicators. A trauma-exposed community sample of 203 participants (M_age?=?35.40 years; 61.10% female) was recruited via Amazon's Mechanical Turk. Participants completed measures of posttraumatic stress disorder (PTSD; PTSD Checklist for DSM-5), depression (Patient Health Questionnaire-9), posttraumatic cognitions (Posttraumatic Cognitions Inventory), affect (Positive and Negative Affect Schedule), count/number of recalled specific positive memories (Autobiographical Memory Test) and accessibility of a specific positive memory (i.e., subjective ease of recalling details of a memory; Memory Experiences Questionnaire-Short Form). Linear regression results indicated that PTSD intrusion severity, PTSD negative alterations in cognitions and mood (NACM) severity, PTSD alterations in arousal and reactivity (AAR) severity, self-blame, and positive affect significantly and negatively predicted the count of specific positive memories. Further, PTSD NACM severity, PTSD AAR severity, negative cognitions about the self, and negative affect significantly and negatively predicted accessibility of a specific positive memory. Thus, count/accessibility of specific positive memories was associated with several post-trauma mental health indicators; this highlights the relevance and potential impact of integrating positive memories into trauma treatment.
