Infant pointing serves an interrogative function

In recent years there has been a resurgence of interest in the motivations behind, and the function of, infant pointing behaviour. Many studies have converged on the view that early pointing reflects a motivation to share attention and interest with others. Under one view, it is the sharing of attention itself that is the ultimate function of pointing, and is an early manifestation of a uniquely human social cognition that is geared towards cooperation and collaboration. In the current study, we tested an alternative hypothesis in which the goal of pointing is not attention sharing itself, but the information-laden response that infants tend to receive as a result of sharing attention. If infants indeed point in order to obtain information, their pointing should be modulated by the perceived ability of the other to provide this information. In Experiment 1, 16-month-olds who interacted with a demonstrably knowledgeable experimenter pointed significantly more to novel objects than infants who interacted with an ignorant experimenter. In Experiment 2, we confirmed that this finding was due to the perceived competence of the experimenter rather than to the different ways in which the experimenter responded to infants' points. Our results suggest that one function of pointing in infancy is to obtain information from others, and that infants selectively elicit desired information from those whom they perceive could competently provide it.     

Nine-months-old infants do not need to know what the agent prefers in order to reason about its goals: on the role of preference and persistence in infants' goal-attribution

Human infants readily interpret others' actions as goal-directed and their understanding of previous goals shapes their expectations about an agent's future goal-directed behavior in a changed situation. According to a recent proposal (Luo & Baillargeon, 2005), infants' goal-attributions are not sufficient to support such expectations if the situational change involves broadening the set of choice-options available to the agent, and the agent's preferences among this broadened set are not known. The present study falsifies this claim by showing that 9-month-olds expect the agent to continue acting towards the previous goal even if additional choice-options become available for which there is no preference-related evidence. We conclude that infants do not need to know about the agent's preferences in order to form expectations about its goal-directed actions. Implications for the role of action persistency and action selectivity are discussed.     

Attitudes about psychotherapy: A qualitative study of introductory psychology students who have never been in psychotherapy and the influence of attachment style

Design: Interviews about attitudes about psychotherapy with 12 undergraduate students who had never been in psychotherapy were analysed using consensual qualitative research. Results: Participants believed that the client role is to disclose, be receptive, and be motivated; that the therapist role is to listen, support, and give advice; and that the therapeutic relationship should be close and personal. Participants had ideas about the benefits (a healing therapeutic relationship, personal and interpersonal changes) and the barriers (self‐stigma and public stigma, difficulty revealing, need to solve problems on own, cost) associated with seeking therapy, and they disliked the idea of being diagnosed. In contrast with participants who were securely attached, those who were insecurely attached more often wanted a professional therapeutic relationship, wanted the therapist to ask questions, mentioned fewer benefits to therapy, and thought that they would have difficulty disclosing to a therapist. Discussion: Implications for changing attitudes about psychotherapy and improving training programs for practitioners are discussed.     

Selectively friending: Racial stereotypicality and social rejection

Three studies show that people whose physical features are seen as more (versus less) racially stereotypical are more vulnerable to social rejection and exclusion from those outside their group. In Study 1, which used an online social networking site, Blacks perceived as more physically stereotypical were found to have fewer non-Black friends, compared to less-stereotypical Blacks. In Study 2, which used an experimental paradigm, requests for friendship made to non-Blacks by more-stereotypical Blacks were more likely to be rejected than those made by less-stereotypical Blacks. Finally, in a college dormitory, people judged to have more (vs. less) racially stereotypical physical features were found to interact less often with outgroup members. This work substantiates a growing body of research demonstrating that people who are perceived as more physically stereotypical of their racial group are particularly vulnerable to discriminatory treatment by outgroup members across a variety of life domains.     

Practical Implementation Science: Developing and Piloting the Quality Implementation Tool

According to the Interactive Systems Framework for Dissemination and Implementation, implementation is a major mechanism and concern in bridging research and practice. The growing number of implementation frameworks need to be synthesized and translated so that the science and practice of quality implementation can be furthered. In this article, we: (1) use the synthesis of frameworks developed by Meyers et al. (Am J Commun Psychol, 2012) and translate the results into a practical implementation science tool to use for improving quality of implementation (i.e., the Quality Implementation Tool; QIT), and (2) present some of the benefits and limitations of the tool by describing how the QIT was implemented in two different pilot projects. We discuss how the QIT can be used to guide collaborative planning, monitoring, and evaluation of how an innovation is implemented.     

Developmental pattern of digit span in Spanish population

This study examined in a Spanish population the developmental pattern of digit span, as an index of one of the components of Baddeley's working memory--the phonological loop. A verbal digit span was administered to 570 participants ranging from 5 to 17 years old. The results indicated that the digit memory span increases until age 17 as opposed to Anglo-Saxon data--where it is established that this span reaches a peak by age 15. Additionally, these results were compared to the performance in the same task of healthy elderly, Alzheimer disease patients, and Frontotemporal dementia patients, examined in a previous study. The analysis shows that the phonological loop is affected by age and not so much by dementias.     

Exploring programmatic moderators of the effectiveness of marriage and relationship education programs: a meta-analytic study

This study uses meta-analytic methods to explore programmatic moderators or common factors of the effectiveness of marriage and relationship education (MRE) programs. We coded 148 evaluation reports for potential programmatic factors that were associated with stronger intervention effects, although the range of factors we could code was limited by the lack of details in the reports. Overall, we found a positive effect for program dosage: moderate-dosage programs (9-20 contact hours) were associated with stronger effects compared to low-dosage programs (1-8 contact hours). A programmatic emphasis on communication skills was associated with stronger effects on couple communication outcomes, but this difference did not reach statistical significance for the relationship quality/satisfaction outcome. There was no evidence that institutionalized MRE programs (formal manuals, ongoing presence, formal instructor training, multiple evaluations) were associated with stronger effects. Similarly, there was little evidence of differences in program setting (university/laboratory vs. religious). We discuss possible explanations for these findings and implications for program design and evaluation.     

Minimizing sleep deprivation effects in healthy adults by differential outcomes

Sleep deprivation reduces vigilance or arousal levels, affecting the efficiency of certain cognitive functions such as learning and memory. Here we assessed whether the differential outcomes procedure (DOP), a learning procedure that has proved useful to ameliorate episodic memory deficits, can also improve memory performance in sleep-deprived participants. Photographs were presented as sample faces. A probe face was then presented for recognition after either short or long delays. In the differential outcomes condition a unique reinforcer followed correct responses. In the non-differential outcomes condition reinforcers were provided in a random manner. The results indicated that the DOP prevented the recognition memory to decrement during the long delay in the control group, replicating previous findings. The sleep-deprived group showed DOP benefits mainly with the short delay, when working memory could be affected by low arousal. These findings confirm that the DOP can overcome impaired recognition memory due to sleep deprivation conditions.
