Long-term transfer of learning from books and video during toddlerhood

Television viewing and picture book reading are prevalent activities during toddlerhood, and research has shown that toddlers can imitate from both books and videos after short delays. This is the first study to directly compare toddlers' long-term retention rates for target actions learned from a video or book. Toddlers (N=158) at 18- and 24-months of age saw an experimenter demonstrating how to make a novel three-step toy rattle via a prerecorded video or a picture book. The toddlers' imitation of the target actions was tested after a specific delay (e.g., 2, 4 weeks), and their performance was compared with that of age-matched controls who did not see a demonstration. The 18-month-olds retained the target actions for 2 weeks, exhibiting forgetting at 4 weeks, whereas the 24-month-olds retained the information for up to 4 weeks, exhibiting forgetting at 8 weeks. Retention rates for books and videos did not differ at either age. These findings demonstrate very impressive retention from a brief two-dimensional media demonstration, and they contribute to our overall understanding of long-term memory processes during infancy.     

From correlates to causes: can quasi-experimental studies and statistical innovations bring us closer to identifying the causes of antisocial behavior?

Longitudinal, epidemiological studies have identified robust risk factors for youth antisocial behavior, including harsh and coercive discipline, maltreatment, smoking during pregnancy, divorce, teen parenthood, peer deviance, parental psychopathology, and social disadvantage. Nevertheless, because this literature is largely based on observational studies, it remains unclear whether these risk factors have truly causal effects. Identifying causal risk factors for antisocial behavior would be informative for intervention efforts and for studies that test whether individuals are differentially susceptible to risk exposures. In this article, we identify the challenges to causal inference posed by observational studies and describe quasi-experimental methods and statistical innovations that may move researchers beyond discussions of risk factors to allow for stronger causal inference. We then review studies that used these methods, and we evaluate whether robust risk factors identified from observational studies are likely to play a causal role in the emergence and development of youth antisocial behavior. There is evidence of causal effects for most of the risk factors we review. However, these effects are typically smaller than those reported in observational studies, suggesting that familial confounding, social selection, and misidentification might also explain some of the association between risk exposures and antisocial behavior. For some risk factors (e.g., smoking during pregnancy, parent alcohol problems), the evidence is weak that they have environmentally mediated effects on youth antisocial behavior. We discuss the implications of these findings for intervention efforts to reduce antisocial behavior and for basic research on the etiology and course of antisocial behavior.     

Hemifacial preferences for the perception of emotion and attractiveness differ with the gender of the one beheld

Though the left cheek appears more emotive, perceptions of attractiveness vary with gender. For the first time, this study assessed the relationship between perceptions of emotion (happiness) and attractiveness in naturalistic photographic portraits. One hundred ninety-two participants (63 male; 129 female) viewed pairs of left and right cheek poses, and made a forced-choice decision indicating which image appeared (a) more emotive and (b) more attractive (order counterbalanced). Half the images were mirror-reversed to control for perceptual biases. Results indicated a striking gender difference: for males, the left cheek appears both more emotive and more attractive; for females, preferences are subject to stronger perceptual influences, with the right cheek bias for emotion and attractiveness reversing to a left cheek bias when images are mirror-reversed. These findings suggest that if you want to show the world your "best side", men should lead with the left but for women, the right cheek is right.     

Influence of bilingualism on memory generalization during infancy

Very few studies have examined the cognitive advantages of bilingualism during the first two years of development, and a majority of the studies examining bilingualism throughout the lifespan have focused on the relationship between multiple languages and cognitive control. Early experience with multiple language systems may influence domain‐general processes, such as memory, that may increase a bilingual child’s capacity for learning. In the current study, we found that bilingual, but not monolingual, infants were able to generalize across cues at 18 months. This is the first study to show a clear bilingual advantage in memory generalization, with more equal or balanced exposure to each language significantly predicting ability to generalize.

Emotional support and counselling for people with visual impairment: Quantitative findings from a mixed methods pilot study

Aims: This paper reports on mainly quantitative findings from a mixed methods evaluation of a new model of emotional support and counselling for people with moderate visual impairment. Method: The CORE Outcome Measure was completed with service users at baseline and post‐intervention to assess the impact of the new service on psychological wellbeing and social functioning. Their perceived needs and expectations of the service were also explored. Results: Of the 35 individuals providing data at each assessment time, mean item scores on the CORE fell significantly (p<.001), taking the sample from within a clinical population before therapy, to a mean score below this following therapy. A more positive outlook accompanied this improvement in functioning. Discussion: Findings from the study augment the growing evidence that emotional support and counselling services can play an important role alongside and within related vision services. Implications for practice: The study indicates that therapeutic input for the visually impaired client group may need to target both wellbeing (feelings about oneself and the future) and problems (depression, anxiety, physical health, and trauma). Conclusions: Our findings suggest that a dual model of emotional support and counselling offers considerable benefit for people with visual impairment.     

Individual differences in the Behavioral Inhibition System are associated with orbitofrontal cortex and precuneus gray matter volume

The Behavioral Inhibition System (BIS) is described in Gray's Reinforcement Sensitivity Theory as a hypothetical construct that mediates anxiety in animals and humans. The neuroanatomical correlates of this system are not fully clear, although they are known to involve the amygdala, the septohippocampal system, and the prefrontal cortex. Previous neuroimaging research has related individual differences in BIS with regional volume and functional variations in the prefrontal cortex, amygdala, and hippocampal formation. The aim of the present work was to study BIS-related individual differences and their relationship with brain regional volume. BIS sensitivity was assessed through the BIS/BAS questionnaire in a sample of male participants (N = 114), and the scores were correlated with brain regional volume in a voxel-based morphometry analysis. The results show a negative correlation between the BIS and the volume of the right and medial orbitofrontal cortices and the precuneus. Our results and previous findings suggest that individual differences in anxiety-related personality traits and their related psychopathology may be associated with reduced brain volume in certain structures relating to emotional control (i.e., the orbitofrontal cortex) and self-consciousness (i.e., the precuneus), as shown by our results.     

Thinking About Your Thoughts: Investigating Different Cognitive Change Strategies

A mainstay technique of cognitive therapy is the cognitive error (CE) method, which aims to mitigate psychological distress by identifying logical errors in thinking and replacing them with alternative, adaptive cognitions. Monson and Fredman (2012) have developed a different cognitive change strategy, named the U.N.S.T.U.C.K., which is predicated on the notion of increasing cognitive flexibility to improve distress. This therapy analogue study (N?=?32) examined the emotional change produced by each strategy and initially tested each strategy??s underlying theory. Both strategies resulted in emotional change, and there was a marginally significant advantage of the U.N.S.T.U.C.K. in producing this change. The U.N.S.T.U.C.K. also resulted in a greater decline in belief in original thought over time. Finally, the interaction between level of belief in new thought and cognitive strategy was a marginally significant predictor of emotional change; there was a stronger relationship between belief in new thought and emotional change for those in the U.N.S.T.U.C.K. group. Limitations and future research directions are offered.     

Handedness differences in information framing

Previous research has shown that strength of handedness predicts differences in sensory illusions, Stroop interference, episodic memory, and beliefs about body image. Recent evidence also suggests handedness differences in the susceptibility to common decision biases such as anchoring and sunk cost. The present paper extends this line of work to attribute framing effects. Sixty-three undergraduates were asked to advise a friend concerning the use of a safe allergy medication during pregnancy. A third of the participants received negatively-framed information concerning the fetal risk of the drug (1–3% chance of having a malformed child); another third received positively-framed information (97–99% chance of having a normal child); and the final third received no counseling information and served as the control. Results indicated that, as predicted, inconsistent (mixed)-handers were more responsive than consistent (strong)-handers to information changes and readily update their beliefs. Although not significant, the data also suggested that only inconsistent handers were affected by information framing. Theoretical implications as well as ongoing work in holistic versus analytic processing, contextual sensitivity, and brain asymmetry will be discussed.
