The Motivational and Instantaneous Behavior Effects of Contexts: Steps Toward a Theory of Goal‐Directed Behavior1

Contextual conditions affect behavior in 2 ways: (a) They confront people with opportunities and obstacles that affect their motivation to take action; or (b) they instantaneously shape performance, regardless of a person's motivation and even without subjective acknowledgment of the conditions. Traditionally in psychology, the immediate behavioral consequences of a context are disregarded. Based on our theory of goal‐directed behavior, we are able to disentangle the instant and the motivational behavioral consequences of contexts. In an example study, 40% of the variation in performance among 660 Swiss and Spanish pupils was explained by motivational differences. Instantaneous constraints and facilitations imposed on people's acts, in turn, revealed a set of Switzerland‐ and Spain‐specific limitations and affordances (hit rate = 97.5%).     

Structural and Community Change Outcomes of the Connect‐to‐Protect Coalitions: Trials and Triumphs Securing Adolescent Access to HIV Prevention,Testing, and Medical Care

Connect to Protect (C2P), a 10‐year community mobilization effort, pursued the dual aims of creating communities competent to address youth's HIV‐related risks and removing structural barriers to youth health. We used Community Coalition Action Theory (CCAT) to examine the perceived contributions and accomplishments of 14 C2P coalitions. We interviewed 318 key informants, including youth and community leaders, to identify the features of coalitions’ context and operation that facilitated and undermined their ability to achieve structural change and build communities’ capability to manage their local adolescent HIV epidemic effectively. We coded the interviews using an a priori coding scheme informed by CCAT and scholarship on AIDS‐competent communities. We found community mobilization efforts like C2P can contribute to addressing the structural factors that promote HIV‐risk among youth and to community development. We describe how coalition leadership, collaborative synergy, capacity building, and local community context influence coalitions’ ability to successfully implement HIV‐related structural change, demonstrating empirical support for many of CCAT's propositions. We discuss implications for how community mobilization efforts might succeed in laying the foundation for an AIDS‐competent community.     

Retrieval attempts enhance learning regardless of time spent trying to retrieve

Attempting to retrieve information from memory is an engaging cognitive activity. We predicted that people would learn more when they had spent more time attempting to retrieve. In experiments 1a and 1b, participants were shown trivia questions for 0, 5, 10, or 30 seconds and then the answer was revealed. They took a final test immediately or after 48 hours. Retrieval enhanced learning, but the length of the retrieval attempt had no effect (i.e., final test performance was equivalent in the 5-, 10-, and 30-second conditions and worse in the 0-second condition). During the initial retrieval attempt, more time did increase recall, suggesting that participants continued to engage in productive retrieval activities when given more time. Showing the answer for longer (7 versus 2 seconds) increased learning in Experiments 2a and 2b. Experiment 3 examined the effect of retrieval success and Experiment 4 replicated the results using different materials. These results have direct implications for current theories of retrieval.     

Profiles of Children’s Thinking About Violence in Families Exposed to Intimate Partner Violence

Intimate partner violence remains a pervasive and common social problem. Evidence indicates that children witness many instances of intimate partner violence. However, the structure of children’s thinking about family violence is still not well understood. This research employed latent profile analysis to identify underlying latent profiles of children’s thinking about violence using the Attitudes and Beliefs About Violence Scale. The analysis identified two latent profiles mostly differentiated by children’s beliefs about whether or not victims of violence deserve to have violence inflicted upon them. Several covariates differentiated members of the two profiles. Suggestions for intervention and practice are included.     

The BUFFET Program: Development of a Cognitive Behavioral Treatment for Selective Eating in Youth with Autism Spectrum Disorder

Selective eating (often referred to as “picky” eating) is common in individuals with autism spectrum disorder (ASD) across the lifespan. Behavioral interventions are widely used to treat selective eating; however, most of these programs are time intensive, have not been evaluated for use in outpatient settings, and do not typically include youth beyond early childhood. Despite the functional impact and risk for negative outcomes associated with selective eating, there are no empirically supported treatments available for older children, adolescents, or adults, either with or without ASD. To address this treatment gap, we developed BUFFET: the Building Up Food Flexibility and Exposure Treatment program. BUFFET is a 14-week, multi-family group cognitive behavioral treatment for selective eating in children (8–12 years) with ASD. In this paper, we will (1) discuss the theoretical conceptualization of BUFFET, (2) describe the treatment content and structure, (3) present feasibility data from the initial pilot trial, and (4) consider next steps in treatment development.     

HCV knowledge among a sample of HCV positive Aboriginal Australians residing in New South Wales

Australian Aboriginal and Torres Strait Islanders are overrepresented in both the prevalence and incidence of the hepatitis C (HCV). HCV knowledge has been associated with a range of positive health behaviours. HCV knowledge has previously been investigated as a single construct; however examining different knowledge domains (i.e. transmission, risk of complications, testing and treatment) separately may be beneficial. This study investigated whether having greater HCV knowledge in different domains is associated with self-reported positive health behaviours. 203 Aboriginal people living with HCV completed a survey assessing HCV knowledge, testing and care, lifestyle changes since diagnosis and treatment intent. Respondents’ knowledge was relatively high. Greater knowledge of risk of health complications was associated with undertaking more positive lifestyle changes since diagnosis. Respondents testing and treatment knowledge was significantly associated with incarceration, lifestyle changes since diagnosis and future treatment intentions. This study illustrates the importance of ensuring that knowledge is high across different HCV domains to optimise a range of positive health behaviours of Aboriginal people living with HCV. Future health promotion campaigns targeted at Aboriginal people living with HCV could benefit from broadening their focus from prevention to other domains such as testing and treatment.     

Using leap motion to investigate the emergence of structure in speech and language

In evolutionary linguistics, experiments using artificial signal spaces are being used to investigate the emergenceof speech structure. These signal spaces need to be continuous, non-discretized spaces from which discrete unitsand patterns can emerge. They need to be dissimilar from—but comparable with—the vocal tract, in order tominimize interference from pre-existing linguistic knowledge, while informing us about language. This is a hardbalance to strike. This article outlines a new approach that uses the Leap Motion, an infrared controller that canconvert manual movement in 3d space into sound. The signal space using this approach is more flexible than signalspaces in previous attempts. Further, output data using this approach is simpler to arrange and analyze. Theexperimental interface was built using free, and mostly open- source libraries in Python. We provide our sourcecode for other researchers as open source.     

The role of higher level adaptive coding mechanisms in the development of face recognition

Developmental improvements in face identity recognition ability are widely documented, but the source of children’s immaturity in face recognition remains unclear. Differences in the way in which children and adults visually represent faces might underlie immaturities in face recognition. Recent evidence of a face identity aftereffect (FIAE), in which adaptation (exposure) to a particular identity causes a previously neutral face to take on the computationally opposite identity, suggests that adults code faces in an opponent fashion relative to an average face. One previous study showed comparable FIAEs in 8-year-olds and adults but did not demonstrate that adaptation was selective for high-level representations in both groups. Using a developmentally appropriate FIAE task, we investigated whether children show adult-like adaptation for facial identity when adapting and test images differ in size. Both age groups showed an equivalent FIAE, suggesting that qualitative changes in the use of higher level adaptive coding mechanisms do not drive the developmental improvements in face recognition ability, at least from 8 years of age.
